The first model, the P.50-I, was a four-engine shoulder-wing monoplane with a single large tailfin and rudder.It was powered by four 544-kilowatt (730-horsepower) Isotta-Fraschini Asso XI.RC V12 engines mounted in tandem pairs on the wings, with each engine driving one three-bladed propeller; two of the propellers were mounted in a pusher and two in a tractor configuration.
Drawing of a centrifugal "fly-ball" governor. The balls swing out as speed increases, which closes the valve, until a balance is achieved between demand and the proportional gain of the linkage and valve.
A back-pressure regulator, back-pressure valve, pressure sustaining valve or pressure sustaining regulator is a control valve that maintains the set pressure at its inlet side by opening to allow flow when the inlet pressure exceeds the set value.
It was used in the astronomical regulator clocks made by his German firm Clemens Riefler from 1890 to 1965, [3] which were perhaps the most accurate all-mechanical pendulum clocks made. An escapement is the mechanism in a mechanical clock that gives the pendulum precise impulses to keep it swinging, and allows the gear train to advance a set ...

In August 2003, Project Gutenberg created a CD containing approximately 600 of the "best" e-books from the collection. The CD is available for download as an ISO image. When users are unable to download the CD, they can request to have a copy sent to them, free of charge. In December 2003, a DVD was created containing nearly 10,000 items. At ...
One of the main results in the theory is that the solution is provided by the linear–quadratic regulator (LQR), a feedback controller whose equations are given below. LQR controllers possess inherent robustness with guaranteed gain and phase margin , [ 1 ] and they also are part of the solution to the LQG (linear–quadratic–Gaussian) problem .
It is well known that in waters colder than 10 °C (50 °F) use of a regulator to inflate a lift bag, or to purge a regulator underwater for just a few seconds, will start many regulators free-flowing and they will not stop until the air supply to the regulator is stopped. Some cold water scuba divers install shuttle (slide operation) type shut ...
