Title: Hand or foot operated accelerator system - has clutch and brake dependent magnetic valve to return to slow running position
Inventor: GOES FRIEDRICH DR ING
IPC: G05G1/46
Filed: 1975-05-30
Abstract: The engine performance regulator can be adjusted by either a normal accelertor pedal or a hand lever capable of pushing or pulling a slide between the full load position and the slow running position. The slide is spring loaded and contains a sliding block (11) provided with a recess (12) into which a pivoted ratchet (15) engages when an electro magnet (14) is excited. In normal working conditions, the engine performance is regulated by the foot pedal control. Should the hand lever control be prefered, the electro magnet is energised and the desired performance selected by the hand lever whereupon the ratchet (15) locks the position. The foot operated accelerator pedal is able to over ride the hand selected position for acceleration purposes, whereby the speed afterwards returns to that selected by hand. In the event of braking or declutching, the electro magnetic switch is deenergised and the performance returns the slow running position.

Title: Numerical position controller for industrial machines - has digital data transmission with high frequency control loop and servo
Inventor: WINGET JAMES LYLE
IPC: G05D3/12
Filed: 1976-03-12
Abstract: The machine tool control circuit has a 1.2 kHz constant output oscillator driving a 720 pole resolver with Sine and Cosine function outputs. A phase detector produces a phase-modulated output which is a linear function of the angular displacement of the resolver armature. This controls a high frequency oscillator running at a nominal 1.2 MHz which varies with the incoming phase-difference signal. A counter produces a BCD conversion of the oscillator frequency and a comparator compares this with the input control data set by the operator and an add or subtract circuit. A second phase detector is also connected to the control loop and this signal operates a servo-motor connected to the operating mechanism of the machine to produce the required movement.
