An F connector is a fitting that connects a coaxial cable to an electronic device or a wall jack.
Traditional coaxial cables were once the standard means of connecting a television to an antenna or cable TV access point. But they are less common now that high-definition and ultra-high-definition televisions make prevalent use of HDMI, fiber optical, and ethernet cables for many of their connections. Still, coaxial cables have their purposes, and your video system may still use them.
A coaxial cable used to bring electronic signals to a television or other electronic device terminates in an F connector. There are several ways these F connectors can be attached to coaxial cable. Professional installers use a coaxial cable stripper, which strips all three layers of the cable at once. Then, they slip on the F connector and secure it with a coaxial cable tool, which presses the connector onto the cable and crimps it at the same time.
Choosing the proper BNC connector to suit the cable for your project usually comes with a price. The price typically needs to be an appropriate assessment of the intending cable. A major issue plaguing most corporate organizations and teams is choosing the right cable. BNC cables remain one of the most used cable types across different industries. This article presents all you need to know about the BNC cable. You will learn about Siamese cables, connectors, benefits, and applications of other types of cables.
There are many definitions of the BNC acronym. Other names include Barrel Nut connector, Bayonet Navy connector, Bayonet Nipple connector, and British Naval Connector. Nevertheless, they are popularly known as the “Bayonet Neill-Concelman.”
Bayonet Neill-Concelman (BNC) is used as a socket and plug for video signals, audio signals, power, and networking systems. These devices are known to offer the best connection to devices. They have a powerful bond with any device of choice.
An IEC connector refers to a type of electronic cable that meet the International Electrotechnical Commission (IEC) standards. The specification for IEC connectors is IEC-60320. The connectors mount with cables are commonly referred to as female connectors or sockets, whereas the connectors mount with panels are known as male connectors or plugs.
IEC-60320 is a standard for male and female connectors used in cables and electric devices such as computers, workstations, laptops, printers and so on. Note that the IEC-60320 standard applies to different range and types of electrical devices. There is a range of standardized connectors that differ in regards to current capacities, temperature ratings and number of conductors. The main purpose of these cables is to attach an electronic appliance to its power source.
The RCA connector was invented in the 1940s and was first used to connect an amplifier to a phonograph. They are sometimes referred to as phono connectors due to this original purpose, even though they can be used to carry both audio and video from many different devices. By the 1950s, the RCA connector had largely replaced the tip ring sleeve (TRS) connector in most high fidelity audio systems, and they remained popular even after the introduction of digital audio and video. Most audio-visual equipment comes equipped with RCA connectors, and some speakers do as well.The Type N connector is a threaded, weatherproof, medium sized connector for durable applications that can easily handle frequencies up to 11 Ghz. This type of connector follows MIL-STD-348 and widely used in lower frequency microwave systems where ruggedness and low cost are needed.
DIN Connectors were originally brought into line in the 1970s. It is an electrical connector, and its architecture has multiple pins that are under a protective circular sheath. Normally, a full-sized DIN Connector contains three to 14 pins with a diameter of 13.2 millimetres.
The term Din connector doesn’t refer to a specific cable. Instead, it requires all the connectors that meet the Din standard.
The circular connector is another name for Din Connector in computer electronics. It’s also used for a digital interface such as musical instrument digital interfaces MIDI.
There are mainly two types of DIN connector. We will discuss them briefly one by one.

[font=-apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Open Sans", "Helvetica Neue", sans-serif]Metal powder is the base materials for the production of metallic component through the conventional powder metallurgy route or the emerging field of additive manufacturing. In any of these process routes, the properties of the finished product depends on the character of the base powder from which it is produced which is equally dependent on the process of production of the base powder. Therefore, there are different methods for producing metal powders with each method offering different particle morphology and purity. These methods include crushing (for brittle material), machining, mechanical pulverization, slotting, electrolysis, atomization of liquid metal using water, nitrogen, argon, or a combination of these, and reduction of metal oxides in hydrogen or using carbon. These metal oxides could be materials such as iron ore or iron oxide generated from pickling plants, in steel strip mills. Other methods include reduction of metal oxide with higher carbon containing, metal powder, chemical decomposition of metal carbonyls, and electrolytic processing of cathodic deposition from molten metal salts; and in some instances, recycling (Sharma, 2011). Each of these methods provides different particle morphology and characteristics. An illustration of typical powder shapes produced from some of these processes is shown in Figures 1 and 2.[/font]
[font=-apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Open Sans", "Helvetica Neue", sans-serif]Nickel powder can be made by a number of different processes, including atomisation from melts or precipitation from solutions. However, these techniques tend to give relatively large particles and can be difficult to control economically at fine particle sizes. The nickel carbonyl gas process on the other hand tends to produce much finer particles, and with sufficient production know-how plus the latest computerised process controls, the particles produced can be precisely controlled to very accurate shapes and tolerances.Copper powder is produced by many processes including chemical precipitation, electrolytic deposition, oxide reduction, water atomization, gas atomization, and jet milling. Accordingly, Cu powders are commercially available in a wide range of particle shapes and sizes. Electrolytic and chemical powders exhibit poor packing and poor rheology in molding, so they have been largely unsuccessful for MIM (Wada, Kankawa, & Kaneko, 1997). Characteristics of examples of the other types are summarized in Table 20.2. Representative scanning electron micrographs are given in Fig. 20.4. These powders all have similar particle sizes but different morphologies. Typical purities reported by the manufacturers are about 99.85 wt%; however, oxygen contents can range up to 0.76 wt%. Powders are usually shipped containing desiccant and proper powder storage is essential to avoid oxidation between purchase and use.[/font]
It is important to try this experiment before doing it as a demonstration, as different samples of aluminium powder can react differently. The induction period for some samples can be quite long. However, this is an impressive and spectacular demonstration, proving that water can be a catalyst. It also shows that aluminium is a very reactive metal, and that its usual unreactive nature is due to the surface oxide layer.
The chemical properties of iodine are very similar to those of bromine and chlorine. However, its reactions are far less vigorous. It can also act as an oxidant for a number of elements such as phosphorus, aluminium, zinc and iron, although increased temperatures are generally required. Oxidation of finely dispersed aluminium with iodine can be initiated using drops of water. The reaction is strongly exothermic, and the excess iodine vaporises, forming a deep violet vapour.
Titanium powder metallurgy can produce high performance and low cost titanium parts. Compared with those by conventional processes, high performance P/M titanium parts have many advantages: excellent mechanical properties, near-net-shape and low cost, being easy to fabricate complex shape parts, full dense material, no inner defect, fine and uniform microstructure, no texture, no segregation, low internal stress, excellent stability of dimension and being easy to fabricate titanium based composite parts.
Here are some questions that beauty technicians have been asking themselves since the appearance and marketing of cosmetic grade boron nitride powder.
Superfine powder is not just a functional material, but also established a solid foundation for the compounding and development of new functional material. The excellent performance of superfine powder exsites in its surface effect and volume effect. the smaller the size of powder, the larger the ratio between Area and volume. Because the BET (surface area) of superfine particle is large, and easy to agglomerate, so we need to do surface treatment/modify to the powder and make it easy dispersing and maximize its performance.Processing and application technology of superfine copper powder has been a major bottleneck for development of the industry. Silty soft copper, grinding processing difficulties, easily oxidized in moist air. Water atomization high cost, low yield, non-uniform particles, and unstable quality. In addition, many newly developed production technology, part of the complex process, the electrical equipment that require high investment, low production yield, high cost, But first let's talk about the cosmetic quality of boron nitride.

What are LEDs and how do they work? |

LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink.
Lifetime of LED Lighting Products
The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time. Unlike incandescent bulbs, LED “lifetime” is established on a prediction of when the light output decreases by 30 percent.
LEDs are incorporated into bulbs and fixtures for general lighting applications. Small in size, LEDs provide unique design opportunities. Some LED bulb solutions may physically resemble familiar light bulbs and better match the appearance of traditional light bulbs. Some outdoor LED light fixtures may have LEDs built in as a permanent light source. There are also hybrid approaches where a non-traditional “bulb” or replaceable light source format is used and specially designed for a unique fixture. LEDs offer a tremendous opportunity for innovation in lighting form factors and fit a wider breadth of applications than traditional lighting technologies.
LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions. That means LEDs are able to use light and energy more efficiently in a multitude of applications. However, it also means that sophisticated engineering is needed to produce an LED bulb that shines light in every direction.
The potential effects of LED street light on health and the environment have been a hot topic of discussion over the last year. As this conversation has evolved, so too have many misperceptions and mischaracterizations of the facts on LEDs. We’ve assembled an array of helpful resources on the topic to help shed some light and are clarify some of the most common myths on LED streetlights.
LED streetlights are no more harmful to humans and animals
Homeowners and businesses have enough to deal with in these harsh economic times than needing to worry about changing floodlights. That’s why LED Flood Light offer the client not only an exceptional dispersion of light but also a bounty of advantages, which are only available when you use LED Floodlights.
In the world of lighting, LED high bay light is a fixture that you would find in a warehouse, a factory, a gymnasium, or any large open area with relatively high ceilings. Many existing high bay lighting and low bay lighting applications utilize high intensity discharge (HID) lamps such as metal halide or high pressure sodium lamps.
Despite their widespread use, HID lamps utilize antiquated technology that costs building managers both directly and i
This approach confined the market for solar LED light to areas closer to the equator with highest average levels of solar irradiation and temperatures that did not affect the performance and lifetime of the DC fluorescent bulbs. It also left the markets in the higher latitudes, typically with higher per capita wealth levels and greater lighting needs rather under-served.

Alle Trainingsprogramme sollten die elektrische Muskelstimulation (EMS) integrieren, um die Muskeln kr?ftig zu kontrahieren. Die besten K?pfe der Leistungssportler sind sich einig, dass EMS ein wertvolles Werkzeug ist, insbesondere auf h?chstem Leistungsniveau. Allerdings verstehen Profis in allen Sportarten – insbesondere auf h?heren Ebenen – die Anwendungen und Vorteile von EMS-Systemen nicht vollst?ndig. Viele Trainer und Trainer haben sich EMS Training Ger?te angeschafft, die Technologie aber noch nicht in ihren Alltag integriert. Mit nur wenig Wissen k?nnen Sie Ihren Sportlern helfen, gro?e Verbesserungen zu erzielen.
Coaches maximieren den EMS-Nutzen, wenn sie die Einheiten in ein gut geplantes konventionelles Training integrieren. Viele Forschungsstudien sagen, dass die alleinige Anwendung von EMS bestenfalls den gleichen Nutzen bietet wie freiwilliges Training; dass EMS nicht besser ist als normale Trainingsmethoden. Da das EMS Training Zu Hause keine Eingaben des zentralen Nervensystems erfordert, ermüdet es das Gehirn eines bereits überforderten Sportlers nicht. Die Kombination aus konventionellem Training und EMS bietet gegenüber jeder Methode allein einen erheblichen Vorteil, da die kumulative Wirkung beider Methoden ein gesteigertes Trainingsszenario mit weniger Energiekosten für den Athleten bietet. Dies ist eine Win-Win-Situation, insbesondere wenn der Stress des Lebens und des Trainings das Nervensystem eines Sportlers überstimuliert.

Cryolipolysis machine — which literally translates into cold (cryo) fat (lipo) destruction (lysis) — was invented, in part, by observing what can happen when kids eat popsicles. No kidding here. The cofounders of this process were intrigued by something called “cold-induced fat necrosis” that was reported to occur after young children ate popsicles that were inadvertently left resting on the cheek for several minutes. Skin samples taken from pediatric patients like these showed inflammation in the fat, but normal overlying skin. Thus, it appeared that fat may be more sensitive to cold injury that other tissue types.
HOW DOES IT WORK?
Coolplas Fat Freeze Machine uses rounded paddles in one of four sizes to suction your skin and fat “like a vacuum,” says Roostaeian. While you sit in a reclined chair for up to two hours, cooling panels set to work crystallizing your fat cells. “It’s a mild discomfort that people seem to tolerate pretty well," he says. "[You experience] suction and cooling sensations that eventually go numb.” In fact, the procedural setting is so relaxed that patients can bring laptops to do work, enjoy a movie, or simply nap while the machine goes to work.
maintain the results of cryolipolysis with a healthy, active lifestyle.
New design Cryolipolysis is safe for all skin types, with no reported pigmentary changes, and is safe for repeated application. Ferraro et al. suggest that patients who require only small or moderate amounts of adipose tissue and cellulite removal would benefit most from cryolipolysis treatment. Contraindications include cold-induced conditions such as cryoglobunaemia, cold urticaria, and paroxysmal cold haemoglobinuria. Cryolipolysis should not be performed in treatment areas with severe varicose veins, dermatitis, or other cutaneous lesions.
HIFU Decide Guide: Which Device is for you?
High-Intensity Focused Ultrasound also known as HIFU machine is a non-surgical, non-invasive treatment procedure that tightens and lifts the skin using ultrasound energy. It is taken to be a safe and effective procedure for tightening the facial skin.
HIFU treatment procedure has loads of advantages over the traditional means of facial improvement: painless, zero incisions, scarring, and recovery time. In addition, it is far less expensive too.
Granted, HIFU is a popular means of looking better. Little wonder that there are tons of clinics and spas that offer services they claim can make you look better. However, that's not enough reason for you to jump on the bandwagon of folks searching for ways to look better
Why Choosing The Right HIFU Device is Important?
Be sure to get a professional assessment before you start your HIFU treatment. This is because a professional and objective assessment from a specialist will help you discover the best form of treatment using the right multifunctional HIFU that is suitable for you.
Ultrasound technology is completely safe and has been used in medicine for decades. It works by contracting and shortening muscle fibers, thus causing the lifting and tightening effect that makes the skin look better.
Lifting, tightening, and fats melting are natural processes that result in a slimmer face, reduced jowl line & facial tightening. Confused about how to go about the HIFU facelift treatment in Singapore?

What is the quality judging standard of switch plug and socket? Switch socket is used to deal with electricity, so it has a great relationship with the safety of power consumption environment. If you buy a poor quality switch socket, it is easy to cause electric shock and fire. Look at the quality of American standard switches and sockets. First look at the appearance, the appearance should be smooth, and the material should be uniform. Look at which material is used and whether advanced plastics are used. Good quality switch sockets usually use PC because the material has some flame retardancy, insulation and impact resistance, and it is not easy to change color.
The quality of the switch plug and socket does not mean that the service life is long, so in addition to the quality, it also depends on the frequency of its use. The frequency of the use of switch sockets is standard, the national standard is 40000 times, some brands just conform to the national standards, some brands exceed the national standards, like the bull's switch sockets can be used 80000 times, is two times the national standard. That is to say, the service life of the same quality switch socket is different.
Electrical strength: when the metal panel American 1 gang 2 way switch is disconnected, an electrical attachment with a nominal voltage of more than 130V should be applied with a sinusoidal frequency of 50HZ2000V for 1 minutes and no scintillation breakdown may occur. Electrical accessories with rated voltage above 130V specified in the socket shall be applied sine wave frequency North 50HZ2000V voltage for 1 minutes. No flashover breakdown will occur.
Light is an important element in human’s daily activities as it provides brightness in the dark. There are varieties of light source that are being adopted in today daily life such as fire, halogen lamp, fluorescent lamp and light emitting diode (LED) lamp. LED has been chosen as one of the most common lighting systems due to the advantage in energy saving, better luminous and it can be used for a longer period of time. Sensors is also focused in current lighting technology. Sensors will act as a residential 1 gang 1 way 16a light switch for Homes and only be functioned as it detects the gesture related to its specification such as motion or darkness. The usage of sensor in lighting system will further improve the efficiency of the system and provides an alternatives for energy saving.
The safety features of BS 1363 adaptor or wall socket is further enhanced with the usage of safety shutters. The safety shutters is used as such that when a plug is withdrawn from it, the white American power electrical double wall socket contacts or the socket holes which carry current supply will be automatically closed. The shutters should be operated by mating the earth pin to the earth hole. The shutter for a particular socket aperture should not be able to closed the shutter for another socket aperture independently (ISO, 2007).In the experiment, plugs and American style single 3 pin socket of rated current 10A are used under conditions of reduction and contact areas and contact vibrations. External heating temperature of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C and 700°C are used to determine the characteristic law of samples. Apparently the plastics insulations of shells are melted and deformed while the metal parts are carbonized but there is no sign of melting and deformation. From the analysis results, it can be concluded that under fault over a small contact area, the plug’s terminal could reach a temperature of 300–400°C and the contact area between plug and socket can reach a temperature of 200–300°C. The major problem in sparking is after melting and carbonizing of insulation material of wall socket, secondary fault including combustion and short circuit may happen directly (Techakittiroj, 2008).

Optimized maintenance is a key competitive advantage for an aggregate producer. Dealing with multiple service providers and brands can become a significant risk as response times, quality and inventories vary across suppliers. For crushers, it’s the spare parts that ensure operational uptime; they enable the metso jaw crusher spares and the process to keep on going. Would it be beneficial to have one premium partner to provide parts and services for all your crushers? We say it is something to consider, but only with the right partner – here’s why.
Sustainability should be considered in all steps of the way, from start to finish. We use certified beech from Europe as the base for our wooden components. Safety is improved by providing part features such as additional lifting lugs and also for example by providing a specialized lifting tool for Metso Outotec-made mantles for third party sandvik jaw crusher spares. Most importantly, your operations become sustainably efficient with one partner that can be trusted to be there now and also in the future.
Although crusher parts may look the same from the outside, they may be very different in terms of quality, fit or materials.Superior Industries Inc., a U.S. based manufacturer and global supplier of bulk material processing and handling systems, says it has entered into a strategic partnership with Europe's largest manufacturer of aftermarket crusher parts. For 40-plus years, CMS Cepcor has manufactured premium cone crusher spares spares for more than three dozen active and classic brands throughout Europe. The parts manufacturer recently expanded its global footprint when it launched CMS Cepcor Americas.
When the wearing of the jaw crusher spares plates is severe, it is a known fact that crusher performance is not ideal, because the empty spaces between the teeth are reduced, encagement happens frequently, the crushing angle is changed or, in other words, production is affected.
This means that, a cost-benefit analysis for changing the worn symons jaw crusher spares plate should be seriously considered, because at a certain point, the difference in production justifies the investment in a new part. We have also observed users crushing even with cracked and perforated jaw plates, without carrying out the correct control and cost x production analysis.

A Look at Two Different Print Technologies: Dye Sublimation and UV |
Posted by: sssff4 - 08-26-2021, 09:30 AM - Forum: My Forum

There are a variety of methods used to decorate plastic products, with one of the most popular processes being dye sublimation. While most people associate dye sublimation paper with textiles and apparel, this is not solely the case, as this process also can be used to decorate a broad array of plastic or rigid substrates.
What is dye sublimation? Sublimation is defined as “a phase transition of a substance from a solid state to a gas while bypassing the intermediate liquid phase.” In the case of dye sublimation printing onto rigid substrates, the disperse dye inks are printed onto a coated medium, which is most often a “transfer paper,” but also can be a “transfer film.” Once printed, these water-insoluble dyes then dry and turn solid as the water solution evaporates. Heat (typically 400°F), pressure and time turn these solid dyes into gas which, upon release from the transfer paper or film, then penetrates the plastic or polyester coating. In addition to dyeing the plastic or rigid substrate, the sticky sublimation paper transforms the dull colors that were originally printed on the transfer paper into incredibly vibrant hues.
The end-product and volume will determine the type of heat press that should be purchased. If decorating mainly flat objects, then a flatbed press is ideal. Flatbed presses can be small (16×20″) presses or large-format presses that can accommodate 4×8′ panels.
If sublimating on 3D objects, then a 3D oven press will be needed. Once again, the oven presses can range from smaller “desktop” units to machines the size of a walk-in room. Instead of printing onto transfer paper, the images will be printed onto transfer film, which is able to conform around the edges of the object being decorated. A fixture is needed to hold both the object and printed film in place. A vacuum hose is attached so the printed film thermoforms around the object and, when the oven heats up to 400°F, the Inkjet Sublimation Paper process takes place.
With dye sublimation, the applications are seemingly endless. The important thing for users to remember is that dye-sublimation takes place at the heat press, not at the printer. However, a high-quality printer with premium RIP software is necessary to produce quality prints with accurate colors and ink drop placement. Dye sublimation ink droplets are extremely small. A colleague best described it by saying, “the largest dye-sublimation ink droplet is smaller than the smallest eco-solvent ink droplet.” What that basically means is that these ink droplets are small, and they need proper control when they jet from the piezo print head. Without proper control, it is not possible to achieve fine lines and details or smooth gradients.
Dye heat sublimation paper requires polyester or plastic for the inks to penetrate into the substrate and dye. The blanks must be able to withstand 400°F heat, pressure and time (which can range from 60 seconds to minutes, depending on size and type of object).
How does UV printing differ from other printing methods?
Ultraviolet (UV) printing is different from tacky sublimation paper or conventional printing methods – including both traditional pigment, solvent inkjet and commercial offset – in many ways. While it is still ink on “paper,” the ink cures through a completely different process and the “paper” ends up being no longer just paper. Instead of having solvents in the ink that evaporate into the air and absorb into the paper, UV inks dry through photoinitiators in the ink and are solidified by UV lamps. When the inks are exposed to ultraviolet energy, they turn from a liquid or paste into a solid. Thus, UV-curable inks are “cured” once they are exposed to the wavelengths of UV energy.

Aluminum building materials is widely used in building because of its intrinsic properties of lightness and corrosion resistance.
Aluminum is used in external facades, roofs and walls, in windows and doors, in staircases, railings, shelves, and other several applications.
Aluminium in building construction
Thanks to its features, there are many benefits that aluminum offers to the construction industry:
This paper contains complete overview of use of Aluminum corbel in building construction. How it is beneficial in modern age building construction. This paper also contains the properties, advantages. Some question arises that whether aluminium is sustainable, fabricated for fast track, requires maintenance, are explained in detail in this paper.While Aluminum railing has a relatively high co-efficient of linear expansion, at 24 X 10-6/’C – in its pure form, the material’s low modulus of elasticity (65,500N/mm2 for 6063 alloy) enables temperature induced stresses to be accommodated. Indeed, these are generally far lower than in a comparable steel structure (M of E = 210,000N/mm2). This is graphically illustrated by Aluminium’s load-deflection curve, which is continuous, without a yield point.
2.4 Guaranteed performance through quality control
Although basic material costs will always be important to specifiers, they should be balanced against the cost of fabrication and subsequent service performance. This is an area where Aluminium, being ideally suited to highly automate manufacturing procedures to exact tolerances, offers many benefits. Aluminium door extrusions, for instance, are subjected to a rigorous quality regime, from hardness testing of the raw extrusion to conical bends, sawing, scratching, gouging, hammering and weight drops to guarantee coating performance. It is this combination of quality control, excellent cost in use and systems technology that has helped develop new markets for Aluminium roof companies in the health, education, leisure and transport sectors where changes in the funding of building procurement, such as PFI and fund-holding schools has changed the emphasis from lowest capital cost to lowest cost in use. Specifiers are increasingly looking for effective systems solutions by involving system suppliers early in the design process to ensure the most elegantly engineered solution at the lowest cost.

The Best Window Curtains, According to Interior Designers |

You may not appreciate the importance of window dressings — which, in addition to looks, provide privacy and block light — until you move into a place with naked windows. Luckily, adding curtains is one of the easier — and less expensive — projects you can undertake to transform a room. To help you dress your windows with the least amount of headache, we turned to 10 interior designers for their favorite curtains, lots of which are surprisingly quite budget friendly. (If you’re shopping for curtains, you’re likely looking at rods, and this list has a bunch of expert-recommended options to choose from.)
Before we get to the blackout curtain— which include a range of ready-made styles in different opacities, colors, and patterns, as well as a couple of custom options — some quick guidelines for how to size the drapery you choose for your space. When it comes to measuring your windows, Megan Hersch, the owner of Studio MG Interiors and online interior-design service RoomLift, says you should measure 12 to 24 inches beyond the window on either side to determine how wide each curtain panel should be, so that you have some gather. In determining the length of your curtain, Hersch says it depends on how formal you want them to look — and how much cleaning you want to do. “I typically measure the drapery so that it just ‘kisses’ the floor,” she says. “This way, nothing is dragging and trapping dirt, but you are sure they don’t look too short.” For a more formal look, she suggests adding an extra 1.5 inches so the drape just “breaks” on the floor. The most dramatic look is to have the panels “puddle” on the floor, which means adding anywhere from 8 to 12 inches to the length of the curtain (the type of fabric, whether stiff like taffeta or soft like velvet, will also determine how naturally it gathers on the floor).
A sheer curtain is a great choice if you want a little bit of everything from your window treatments — privacy, light, and looks — without having to commit too heavily to any one of those needs. As Megan Huffman, a designer with the online interior-design service Modsy, puts it, sheer curtains “provide the ability to allow natural light into a space and help brighten up dark rooms while still allowing privacy,” adding that, “there’s nothing I love more than a crisp, white, sheer curtain.” She recommends this pair from West Elm, which features a subtle crosshatch pattern that adds a bit of texture. If you like the look of sheer curtains during the day but also want to keep light pollution from coming through at night, Huffman says these can easily be hung on a double curtain rod with a pair of thicker, more opaque blackout curtains.
For faux linen blackout curtain, these are Mulhearn’s go-tos. She likes that they’re affordable, come in a variety of neutral colors, and are available in various lengths, from 63 inches to 108 inches. They also have a grommet top, which means you don’t need to get additional curtain rings to hang them from a rod.
Take note of the word parted. Beyond the myriad practical aspects, window treatments, from simple to elaborate, offer us moments of communion, as human hands—whether your own or those of Lady Dudley’s housekeeper—adjust them at will. There are aural pleasures too, from the clicking of curtain rings to the swish of fabric to the creak of shutters to the whir of roller blinds. Literally, the beauty of geometric blackout curtain is an open-and-shut case.
