Filed: 1934-11-27
Abstract: 438,092. Preventing unauthorized use. RAIMANN, A., 6, Wenhartgasse, Vienna. Nov. 27, 1934, No. 34077. Convention date, Nov. 27, 1933. [Class 7 (ii)] [See also Groups XXXVII and XXIX] A valve controlling the fuel supply to the engine of a motor vehicle is controlled by an electromagnet, the energizing circuit of which is controlled by a switch with a combination lock. The electromagnetically-operated valve comprises an electromagnet w with a hollow core b connected to a core flange c by a non- magnetic sleeve i and adapted to attract an armature d which itself attracts a ball g so as to allow the fuel to pass round the ball and through the hollow armature d and core e. A spring f returns the parts when the magnet w is de-energized. The switch comprises a rotary shaft r carrying a sector s which is prevented from rotating by two balls p engaging recesses t in the sector s. To unlock the switch, four discs u must be rotated by handles w through predetermined positions, after the manner of a combination lock, until recesses v in the discs u are in a position to receive the balls p. The switch has three positions. In position I the ignition is earthed, by a button 3 on the sector s engaging a contact spring 2, and a circuit 8 to the horn and head-lights is open because a contact connected to the circuit 8 is out of engagement with a spring contact 6. The handle H connected to the shaft r also lies over a screw 17 which secures a cover to the switch casing, so that the cover cannot be removed when the switch is in this position. In position II which can only be obtained after the combination has been moved into unlocking position, the button 3 disengages the spring 2 so that the ignition becomes operative and the spring contact 6 is pressed by a button into engagement with the contact associated with the circuit 8, thus closing the horn and head-light circuit. In position III the button presses the spring contact 6 also into engagement with a contact 10 connected to a conductor m leading to the electromagnet w controlling the fuel supply to the engine. This is the position for normal driving.

Title: Improved electric remote control system
IPC: G08C19/38
Filed: 1947-12-29
Abstract: 647,834. Electric control systems. GRETENER, E. Dec. 29, 1947, No. 34327. Convention date, March 25, 1946. [Class 40 (i)] The transmission error in a follow-up system is compensated by measuring the error in a duplicate transmission system or its mechanical or electro-mechanical equivalent, and injecting the error so obtained in the reverse sense into the main system. As shown, the input rotation is applied at 16, Fig. 1, through gearing to two transmitters 10, 22 which through transmission lines 21, 33 drive the respective receivers 11, 30. The main receiver 11 drives the load 12 which is simulated by a dummy load 32 driven by the receiver 30 so that each system is subject to the same phase or transmission error. The phase error in the duplicate system is measured by a differential gear'14, having sun wheels driven by the transmitter and receiver respectively, and is applied through gearing 18 to adjust the brushes 15 of the primary transmitter 10 in the corrective sense. For mechanically simulating the load, Fig. 2, the input rotation is applied to a shaft 65 which through a spring 60 and damping motor 61 drives a shaft 64 connected to a simulated load 63. The spring 60 simulates the rigidity of the transmitter motor, and the damping motor 61, which has a moment of inertia equal to that of the receiver rotor and may be a separately excited short-circuited generator, simulates the effect of the receiver angular velocity on the error angle. The shafts 64, 65 drive the input shafts 68, 69 of a differential 67. The differential output shaft 66 which drives a further damping motor 62 simulating the damping between the receiver rotor, and the magnetic field it follows moves in accordance with the error angle and this movement is fed into the system by connecting shaft 66 to the brush assembly 15, Fig. 1. Alternatively, the error may be injected into the system at the receiver, Fig. 3 (not shown), by shifting the brush assembly thereof, the receiver in this case being of similar construction to the transmitter 10 of Fig. 1. The Specification as open to inspection under Sect. 91 describes an arrangement, Fig. 2 (Cancelled), in which two duplicate transmission systems 35, 36 each corresponding to 13 in Fig. 1, are driven in parallel from the input shaft 16 whereas their error angle outputs are connected in cascade through differentials 37, 41 to adjust the brush assembly 15 of the main transmitter 10. Fig. 3 (Cancelled) shows a resistance transmitter construction in which the input shaft 49 carries a coil 52 fed with D.C. over slip-rings 53, 54. Tappings on the coil are connected to a commutator 57 rigid therewith and potentials are taken by the three " phase " brush assembly 15 over slip-rings 59 to the receiver. This subject-matter does not appear in the Specification as accepted.

Abstract: 1347056 Fluid-pressure servomotor systems CONSTANTIN RAUCH 26 July 1971 [5 Aug 1970] 34899/71 Heading G3P Two hydraulic pumps 1, 2 driven by a common means are each provided with an output regulator responsive to the fluid pressures in both delivery lines 3, 4. The pump 1 has a servomotor 5 controlled by a pilot valve 11 responsive to the pressure between a fixed restrictor 15 supplied from the delivery line 3 and a variable restrictor 17; a further variable restrictor 24 responsive to the pressure in the delivery line 4 is arranged in parallel with the restrictor 17. A similar arrangement controls a servomotor 6 for the pump 2 in accordance with the pressures in the lines 3, 4. If an increase in pressure occurs, for example, in the delivery line 4 the restrictor 24 increases the pressure applied to the pilot valve 11 to reduce the output of the pump 1. Relief valves 21, 22 may each be replaced by a pressure responsive valve serving as a further control valve for its associated servomotor which is connected through a mechanical linkage to a further variable restrictor in parallel with the restrictor 23 or 24. The arrangement is such that when maximum delivery pressure is reached in line 4, for example, the further variable restrictor is opened to increase the output in the line 3 from the pump 1. In both embodiments each servomotor is connected to its pilot valve by a feed-back spring having a characteristic which keeps the product of pressure and rate of flow constant.
