Title: Improvements in and relating to setting devices for the accelerator pedals of motor vehicles
IPC: B60K26/02
Filed: 1964-06-04
Abstract: 1,001,217. Accelerator setting devices. H. GUSSENBAUER, K. GUSSENBAUER, and E. ULLMANN. June 4, 1964, No. 23136/64. Heading B7H. In a device for retaining the accelerator pedal of a motor vehicle in a predetermined position, a rotatable drum 2a is retained in the desired setting by a coiled spring 7 engaging frictionally therewith and is connected to a shaft 5 in the accelerator linkage by means providing for additional opening of the throttle without losing the initial setting when accelerating, and for automatic abolition of the restraint imposed on the linkage when the clutch or brake is actuated, again retaining the initial setting. The drum 2a is freely mounted on the shaft 5 and is encircled tightly by the spring 7 which is fixed at one end 7a and free at the other 7b. A pin 28 carried by a plate 30 slidable on the shaft 5 is urged by a spring 31 through a bore 29 in a second drum 2b secured to the shaft and into a bore 27 in the drum 2a. For the initial setting of the drum 2a, a slider 3 or lever connected by a flexible cable 20 or linkage to an actuator knob (not shown) is advanced by a spring 18 to raise the free end 7b of the spring 7 by means of a ramp 13 and disengage the spring from the drum 2a, the drum then being rotated against the pressure of a return spring 38 by depressing the accelerator pedal and retained in the desired position by operating the actuator knob to retract the slider 3. When accelerating, the slider 3 is further retracted by means of the actuator knob so that a nose 14b thereon engages the plate 30 to withdraw the pin 28 from the bore 27 and into a recess 37 permitting the shaft 5 to rotate through an additional 90 degrees in the throttle opening sense. A slider 33 or lever actuated by flexible cables 20a, 20b to the clutch and brake pedals is displaced when either pedal is depressed to engage the plate 30 and withdraw the pin 28 clear of the hole 27 and the recess 37, thereby allowing unrestricted movement of the shaft 5.

Abstract: 450,061. Valve circuits. AKTIEBOLAGET STERN & STERN, 12, Gavlegatan, Stockholm. Aug. 21, 1935, No. 23507. Convention date, Aug. 23, 1934. [Class 40 (v)] The disadvantage of the voltage drop across the smoothing choke of a mains supply system for thermionic valves, is overcome by taking the anode supply for the output valve R or other stages from a point A between the choke L1 and the rectifier 4 or mains. The increase in hum is compensated by feeding into the grid circuit of valve R a ripple component of such phase and magnitude as to oppose the hum component in the anode circuit, this component being derived from an auxiliary winding L2 coupled to the choke L1. The latter may be constituted by the field winding of a loud speaker,

Abstract: 724,637. Switching systems; transformer systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 26, 1953 [Aug. 29, 1952], No. 23568/53. Class 38 (4). In a variable voltage supply system for an aerodrome lighting, or other, load 10 as described in Specification 721,112, the manuallyoperated switches 20-22 controlling the tapchanging relays 14-16 are now in the form of push-buttons and the relays have further auxiliary contacts 28-30 which maintain the relay energized after release of the associated push button. Further, the ratio of the impedance of the coil of an operated relay to its impedance in the inoperative condition of the relay is now made such that the voltage reduction across the coil of an operated relay consequent upon the connection in parallel therewith of the coil of an unoperated relay is sufficient to cause release of the operated relay, so that the condenser 24 becomes effective to boost the coil current of the unoperated relay to a pull-in value and so effect a tap change. A tuning condenser 31 automatically switched across any operated relay assists in obtaining the necessary impedance ratio. The push buttons may be located remote from the relays, say at 33, necessitating long connecting leads 32, in which case compensation for voltage loss in the leads may be obtained by arranging that the overall reactance of the series-connected elements 23, 24 is capacitative and resonates with the inductive reactance of any relay in its unoperated condition.
