Centrifugal governors are used in many modern repeating watches to limit the speed of the striking train, so the repeater does not run too quickly. Another kind of centrifugal governor consists of a pair of masses on a spindle inside a cylinder, the masses or the cylinder being coated with pads, somewhat like a centrifugal clutch or a drum brake.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
Bridgeville, California (population 25) was the first town to be sold on eBay in 2002, and has been up for sale three times since. [1] In January 2003, Thatch Cay, the last privately held and undeveloped U.S. Virgin Island, was listed for auction by Idealight International. The minimum bid was US$3 million and the sale closed January 16, 2003. [2]
Electronic regulators as used in modern railway sets where the voltage is raised or lowered to control the speed of the engine Mechanical systems such as valves as used in fluid control systems. Purely mechanical pre-automotive systems included such designs as the Watt centrifugal governor whereas modern systems may have electronic fluid speed ...
Centrifugal switches were also used in early electric fans, particularly those made in the 1900s and early 1910s. [citation needed] In aircraft, a centrifugal switch is used to control the starting and ignition circuits, the governed speed indication circuit and the overspeed protection circuit of the auxiliary power unit. This switch is ...
Many early turbojet engines used centrifugal compressors as they were robust and simple to design. Pages in category "Centrifugal-flow turbojet engines" The following 49 pages are in this category, out of 49 total.
The ferroresonant transformer, ferroresonant regulator or constant-voltage transformer is a type of saturating transformer used as a voltage regulator. These transformers use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output voltage with a varying input current or varying load.
The General Electric/Allison J33 is an American centrifugal-flow jet engine, a development of the General Electric J31, enlarged to produce significantly greater thrust, starting at 4,000 lbf (18 kN) and ending at 4,600 lbf (20 kN) with an additional low-altitude boost to 5,400 lbf (24 kN) with water-alcohol injection.
