Patent GB-719409-A (GB)
Title: Automatic electrical circuit-breakers
IPC: H01H73/30
Filed: 1952-03-10
Abstract: 719,409. Automatic circuit-breakers. ALLARD, G. E. March 10, 1952 [March 27, 1951; June 2, 1951], No. 6201/52. Class 38(5) An automatic circuit-breaker has a movable contact actuated by or carried on an arm biased to the " open " position, the arm normally being held by an abutment in the closed position and being capable of pivotal movement about a fulcrum and of a further movement due to movement of the fulcrum in a slide when the abutment is withdrawn by a fault-responsive device, e.g. a bimetal element. In one form, Fig. 2, depression of a button 12 pivots the arm 3 counter-clockwise about the abutment 9 so that a pivot pin 4 on the arm is engaged and held by a hook 10 to hold contacts 1, 2 closed against the bias of a spring 6. When a bimetal element 17 deflects to the right on fault, abutment 9 is withdrawn from under arm 3 which is then pivoted clockwise about pin 4 to separate the contacts until the hook 10 is disengaged from the pin 4 by a pin 19 on the arm 3 which thus moves bodily upwards, with pin 4 moving in the slide 5. The abutment 9 may be manually withdrawn by a further button. The bimetal may be adjusted by a screw 24, and the arm 3 has a weight 18 to prevent shock operation thereof. In a modification, (Fig. 6, not shown), the arm 3 also carries an arcing contact, and a hairpin-shaped spring 6 is used. In either arrangement, the bimetal 17 may itself form the abutment. In a further arrangement, (Figs. 7, 14, 15, not shown), the arm 3 has an insulating portion bearing on a separate contact-carrying member. In Fig. 8, the spring 6 is arranged between the pin 4 (which is at one end) and the abutment 9, the contact 2 being attached to arm 3 by a member 33. When released, arm 3 pivots about pin 4 into position 3<SP>1</SP> where it engages a stop 35 and then, when pin 4 is released, to position 3<SP>11</SP>, the stop 35 now acting as the pivot. In a modification of this, (Fig. 9, not shown), the member 33 acts on, instead of carrying, the movable contact, and in Fig. 10 (not shown), the arm 3 is rigidly linked to a contact-carrying arm. In Fig. 11, the hook 10 is replaced by a member 53 co-operating with a lever 48 pivoted at 51 on a rod 49 fast with pin 4, the button 12 being linked to lever 48 at 52. When the arm 3 is released, a portion 47 of member 53 is depressed to release the lever 48 and pin 4. In a further modification of Fig. 2, the button 12 is connected to the arm 3 over a spring instead of rigidly, (Fig. 12, not shown). In Fig. 13, the contact 2 and pin 4 are at opposite ends of arm 3, with the abutment 9 in the centre. On release, the arm moves to position 3<SP>1</SP> about pin 4 and then to position 3<SP>11</SP> about the stop 35.

Abstract: 650,272. Hydraulic shock absorbers. NEWTON, N. B. March 1, 1948, No. 6375. [Class 108(iii)] A hydraulic shock absorber of the kind comprising a piston movable within a cylinder proper, enclosed within an outer cylinder, the volume of which is connected to one end of the cylinder proper and forms a closed reservoir and air space to act as a pressure and/or compensation volume for piston rod displacement within the cylinder proper, is characterized by a filling tube having its inner end located in the reservoir at the predetermined correct liquid level therein and its outer end accessible at one end of the shock absorber and adapted to receive the nozzle of a filling gun or pipe. In the arrangement shown, in which a liquid reservoir space is formed between an outer cylinder b and an inner liquid-filled cylinder a, a filler tube i, extends from the lower end of cylinder b and terminates at the normal liquid level j in the reservoir, the level j shown corresponding to a non-vertical mounting position of the shock absorber. A socket i<SP>1</SP> at the lower end of the tube i is adapted to receive the end of a filling gun. A piston c, slidable within the cylinder a, is connected by a rod d to a mounting eye e carrying a housing f for a heavy coil spring g the upper end of which abuts a flange b<SP>3</SP> of a ring b<SP>2</SP> securing a closure cap b<SP>1</SP> of the outer cylinder b.

Abstract: 809,348. Brake operating mechanism. YALE & TOWNE MANUFACTURING CO. Feb. 26, 1957 No. 6399/57. Class 103 (1). In brake control mechanism for an industrial truck, in which a pedal 26 is provided for actuating hydraulic master cylinder for applying the service brake and a pedal 42 is provided for actuating an emergency brake, a detent means holds the emergency brake in the applied position once it has been applied and movement of the pedal to apply the service brake releases the emergency brake from the detent means. In the brake-released position shown in Figs. 1 and 2, both pedals 26 and 42 are in their inoperative positions, the emergency brake shoe 11 being held out of engagement with the brake drum 12 fixed on drive shaft 13 rotating with the wheels of the truck. Actuation of emergency brake pedal 42 moves cam 43 into contact with adjustable head 18 to apply the emergency brake which is held in engagement by the upward movement of the ratchet 46 pivoted to cam 43 such that ratchet teeth 49 engage with pawl 37 fixed to a portion of the service brake pedal.

Abstract: 734,802. Producing combustible gases. GAS COUNCIL. Aug. 9, 1954 [March 9, 1953], No. 6498/53. Classes 55.(1) and 55 (2). In a process of producing combustible gases methanol is vaporized in a boiler 1 and the vapour is converted by thermal decomposition into carbon monoxide and hydrogen by passing it via pipe 4 through a bed of solid carbonaceous fuel in a conventional water gas generator 7 at a temperature of at least 700‹ C., the supply of methanol vapour being intermittently interrupted to allow reheating of the fuel bed by blasting with air. Steam may be added to the methanol vapour and the combustible gases produced may be enriched by the thermal decomposition of a hydrocarbon oil in the presence of the gases. The methanol employed in the process may have been obtained by catalytic synthesis from a mixture of carbon monoxide and hydrogen produced by the gasification of solid carbonaceous fuel.

[Also in Divisions G2-G3] The armature 3 of a synchronous motor B is supplied with constant amplitude pulses of variable mark/space ratio from a frequency converter A comprising an A.C./D.C. converter 1 and a thyristor inverter 2 controlled by converters 5, 6 which respectively determine the frequency and width of the output pulses from the inverter. The converter 5 is in turn controlled by the output of a comparator 7 fed with signals representative of the actual pulse frequency and a reference frequency corresponding to the desired motor speed. The converter 6 is controlled by a comparator 8 fed with signals representative of the measured load angle of the motor and a reference load angle, such that random variations of load torque are damped out. Periodic variations in load torque are compensated by a cyclic programmer or function generator 11 which produces a signal whose period is determined by the actual motor speed and whose shape, amplitude and phase are predetermined in accordance with the operating conditions of the motor to provide optimum control. The output from programmer 11 is fed to a circuit 10 which combines this signal with three other signals respectively representative of:- (1) A reference excitation current for the field winding 4 of the motor. (2) The output of a transducer 12 fed from a comparator 13 providing an error signal in accordance with the variation from a set value of the A.C. voltage supplying the converter 1.
