Hoyt Archery is an American manufacturer of recurve and compound bows located in Salt Lake City, Utah. [1] Most notable for their competition recurve bows, which are featured prominently in the Olympics; every gold medalist in individual archery at the 2012 Summer Olympics shot a Hoyt recurve. [ 2 ]
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
External access point for fire sprinkler and dry standpipe at a building in San Francisco, US Antique wet standpipe preserved at Edison and Ford Winter Estates. A standpipe or riser is a type of rigid water piping which is built into multi-story buildings in a vertical position, or into bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water ...
This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...
Riser clamp for a standpipe through-penetration firestop inside a fire hose cabinet under construction. A riser clamp is a type of hardware used by mechanical building trades for pipe support in vertical runs of piping (risers) at each floor level. The devices are placed around the pipe, and integral fasteners are then tightened to clamp them ...
The International Electrotechnical Commission (IEC; French: Commission électrotechnique internationale) is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies.
Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside the ducts. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to ...
Diagram of recoil mechanism, British 60-pounder gun Mk.I, 1916 The idea of using a water brake to counteract the recoil of naval cannons was first suggested to the British Admiralty by Carl Wilhelm Siemens in early 1870s, but it took about a decade for other people (primarily Josiah Vavasseur) to commercialize the idea.
