Cut-away drawing of steam engine speed governor. The valve starts fully open at zero speed, but as the balls rotate and rise, the central valve stem is forced downward and closes the valve.
A shunt charge controller or shunt regulator diverts excess electricity to an auxiliary or "shunt" load, such as an electric water heater, when batteries are full. [ 7 ] Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level.
Older distributor designs used a cam on the distributor shaft that operates the contact breaker (also called points). Opening the points causes a high induction voltage in the ignition coil. [ 1 ] This design was superseded by an electronically controlled ignition coil with a sensor (usually Hall effect or optical) to control the timing of the ...

A demand controlled regulator provides a flow of breathing gas at the ambient pressure (which varies by depth in the water). Pressure reducing regulators are also use to supply breathing gas to surface-supplied divers, [5] and people who use self-contained breathing apparatus (SCBA) for rescue and hazmat work on
The model selected weighed 13.5 lb (6.1 kg). [22] It had a 3 in (76 mm) diameter impeller and was capable of spinning at up to 70,000 rpm. [25] The turbocharged Corvair engine did not use a wastegate to limit boost pressure. Instead, boost was controlled by an exhaust system designed to create back-pressure sufficient to limit the maximum boost.
Maps and electoral vote counts for the 2012 presidential election. Our latest estimate has Obama at 290 electoral votes and Romney at 191.
The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. The 7803SR from Datel is a full switching power supply module (designed as a drop-in replacement for 78xx chips), and not a linear regulator like the ...
