A door closer is a mechanical device that regulates the speed and action of a door’s swing. [1] Manual closers store the force used to open the door in some type of spring and reuse it to close the door. Automatic types use electricity to regulate door swing behavior. Door closers can be linked to a building's fire and security alarm systems. [2]

Cleco (Cleko) fasteners on an aircraft wing. A cleco, also spelled generically cleko, is a temporary fastener developed by the Cleveland Pneumatic Tool Company. [1] Widely used in the manufacture and repair of aluminum-skinned aircraft, it is used to temporarily fasten sheets of material together, or to hold parts such as stiffeners, frames etc together, before they are permanently joined.
Pneumatic telescoping cylinder 5-stage, double-acting, demonstrating full extension and retraction. A double acting cylinder is extended and retracted using hydraulic or pneumatic pressure in both directions. Double acting telescopic cylinders are thus much more complex in design than the single acting type.
A negative clamp is the opposite of this—this clamp outputs a purely negative waveform from an input signal. A bias voltage between the diode and ground offsets the output voltage by that amount. For example, an input signal of peak value 5 V (V INpeak = 5 V) is applied to a positive clamp with a bias of 3 V (V BIAS = 3 V), the peak output ...
Using the same type of system as a hydraulic launch, a pneumatic launch uses compressed air to launch the vehicle. The technology was developed by S&S as the Thrust Air 2000 model. The first coaster of this type was the Hypersonic XLC, opened at Kings Dominion in Doswell, Virginia, USA in 2001. This coaster closed in 2007.
The system was developed in 1934 [1] [2] by George H. Gascoigne and his colleagues in Reading, England for making cows' milking stalls. [2] It was advertised to industrial chemists in 1944, [ 3 ] marketed in the UK in the 1950s as a cattle control system, [ 4 ] and used for storage systems in factories in the 1960s. [ 5 ]
