Patent EP-0035900-A1 (EP)
Inventor: SWARTZ HAROLD LEE
IPC: G05D3/20
Filed: 1981-03-09
Abstract: A synchro resolver angular position sensor provides the sine and cosine of angular position by applying a square wave excitation from an amplifier 27 to the rotor winding 19 of a resolver 18. The corresponding square wave outputs of the sine and cosine windings of the resolver stator 20 are sampled in time synchronism with the excitation at a predetermined time phase of the square wave excitation cycle. The sampled sine and cosine amplitudes are converted into digital format via an analog-to-digital converter 33, 34, for application to a digital processor. The upper corners of the positively-going leading edges and the lower corners of the negatively-going leading edges of the square wave excitation waveform are rounded to minimise ringing of the sine and cosine square wave outputs from the resolver 18.

Abstract: A flyweight governor comprising first and second sets of flyweights disposed pivotably on a flyweight support, the flyweights of the first set are arrested by stops after having traversed an idle speed angle of traverse ( alpha LL), on which stops the flyweights of said second set rest only after having traversed the total angle of traverse ( alpha max). The flyweight masses of the first set of flyweights acting only in the idle speed control have, in their position of rest, an outer contour which is, in comparison to said second set of flyweights, displaced further outwardly with an inclination angle ( beta LL) to the rotational axis (A) corresponding to the idle speed angle of traverse ( alpha LL). The flyweight governor can be used in particular for the idle speed-maximum speed rpm governors of Diesel engines for vehicles and causes a large reduction of the centrifugal forces ordinarily appearing at maximum rpm, while at the same time allowing an increase in the performance capacity in the idle speed control range.
