Screen Curtain is a Mac OS X application that takes up as little screen space as possible. Its interface is simple and unobtrusive, with a small icon in the menu bar that contains all the necessary options and commands. It can be controlled directly from the Dock or even set to open on boot up.
Color shells
Color shells are after-the-fact devices that collect excess color from the curtain web. Using a special recovery system, the recovered colors are recirculated to the first and second curtain heads. Figures one and two show how color shells are used in curtain application. Figures three and four show how color shells are recovered.
Guide plates are used to align the edge portions of color curtains. These plates are generally thin and have a low coefficient of friction. This allows the application of a stable two-layer coating with little color loss.
Guide plates
Guide plates for curtain application are rigid plates that engage with the curtain rod and guide the curtain as it slides on the rod. The plates typically include a receptacle for receiving the end of the rod, and have a yieldable part that engages the surface of the curtain opposite to the plate’s contact with the rod.
Stability of edge portions
Stability of edge portions in curtain application is one of the main factors that determine the stability of the entire curtain. These edge portions may be straight or have a curved shape. They can also have other profiles, including top and side profiles, and can be of any regular or irregular shape.
Insect air curtains
Air curtain effectiveness in the control of bees was evaluated using a controlled experiment. In this study, researchers exposed the air curtain to bees during a controlled feeding session. They found that the efficiency of the insect barrier decreased with decreasing airflow velocity, which resulted in a higher number of bees in the building.
Insect air curtains are a good choice for cafes, restaurants, and other commercial environments, since they provide an effective barrier against flying insects. These curtains have an air jet at each end, which creates a separation zone protected by two air barriers. The patented air jets have been proven to be effective against bees, which are very strong fliers.
Light curtains
Light curtains are opto-electronic devices used to protect personnel near moving machinery. The use of moving machinery poses a high risk to personnel, and light curtains offer an alternative to traditional mechanical barriers. Light curtains can be placed anywhere personnel may be exposed to dangerous equipment. The devices are also cost-effective. These advantages make them an excellent choice for industries.
The GL family of light curtains offers several different features. The high-powered GL-R Series has built-in alignment indicators, while the GL-S Series is compact for installation in narrow spaces. Several wiring systems are available, including optical synchronization, one-line synchronization, and wired synchronization. Light curtains require regular maintenance. A misaligned or contaminated light curtain can reduce its detection range and reduce the received light intensity.
Magnetic door switch
A magnetic door switch for curtain application is a device that is installed between the door and curtain tracks. It is designed to open and close the curtain based on a pressure sensor. It is typically installed by an electrician. You may need to install the switch manually or use a control panel. If the switch is for a heated air curtain, you’ll need a separate heat switch control panel mounted nearby.
These devices work with either battery or solar power. Unlike a traditional door switch, magnetic door switches work by using a set of magnets on the door. When the door is opened, the switch will turn on the air curtain, and will turn it off when it closes. Magnetic door switches have a wide range of uses.
