Title: Improvements in electromagnetic relays
IPC: H01H51/32
Filed: 1925-05-07
Abstract: 253,328. Western Electric Co., Ltd., (Western Electric Co., Inc.). May 7, 1925. Contact-making relays. - Voice-frequency relays comprise, a short-circuited coil loosely supported in a magnetic field and so arranged that an induced current flows in the coil causing it to vibrate and make loose contact between contact members in the controlled circuit. As shown in Fig. 1, the short-circuited coil 12 is carried by a bar 7 which is loosely supported on eyes 5, 6 which form contact members in the circuit of the energizing coil 17 of a second relay. The coil 12 is disposed in the air gap of an electromagnet 2 with a winding 18 energized by direct current. Immediately beneath the coil 12 is rigidly supported a coil 15 which is supplied with alternating current from a generator 16, the vibrations of the coil 12 thereby produced causing intermittent contact between the bridging- bar 7 and its supporting eyes 5, 6 and so reducing the holding force of the coil 17 to a value at which it is insufficient to retain its armature in the closed position. In the modified form of the relay shown in Fig. 3, the electromagnet 2 is replaced by a horse-shoe permanent magnet 40 with a keeper 20 around which are disposed the loosely-supported short-circuited coil 24 and two serially connected windings 21, 22 adapted to be energized from the alternating-current generator 23. Specification 224,940 is referred to.

Title: Improvements relating to the control of internal combustion-electric power plant
Inventor: RAMSDEN HERBERT KAYE
IPC: B60L50/10
Filed: 1951-05-23
Abstract: 703,649. Automatic speed control systems for engine-electric power plant. METROPOLITANVICKERS ELECTRICAL CO., Ltd. March 27, 1952 [May 23, 1951], No. 12074/51. Class 38 (4) Control apparatus for maintaining constant engine speed in internal combustion engine-electric power plant, such as used for vehicle propulsion; comprises a single regulator AR controlled by fluid servo-mechanism SM, X, Y, EG in accordance with engine speed and operating both to control the resistance in the generator field circuit and to insert. or remove, steps of motor field weakening, the arrangement being such that when the motor is accelerating and when the generator field resistance has been reduced to its minimum value the introduction of a step of motor field weakening is accompanied. by a simultaneous and predetermined increase in generator field resistance to avoid temporary overload of the engine and consequent hunting of the control system. The generator field resistance is again reduced to its minimum value prior to the introduction of a further step of motor field weakening The sequence of operations reverses when decelerating. The regulator may comprise a contact arm R movable by the, servomotor SM over a series of stud contacts and which, over the last half of its travel also cooperates with arcuate contacts FC1-FC3 for sequentially energizing contacts F1-F3 for connecting diverter resistances across the motor field winding. Over the first half of its travel, the arm R progressively removes from the generator field GF sections of resistance connected between adjacent studs. Studs p-s are so interconnected with the studs of the second half of the regulator that when arm R engages contact FC1 the sections of generator field resistance between studs p, s are re-introduced. Continued anticlockwise movement of the arm progressively cuts out these sections until the arm reaches contact FC2, when the sequence repeats. The engine governor EG controls the servomotor SM by supplying fluid to pipe X or Y according as to whether engine speed is below or above a predetermined value. A relay CLR responsive to excessive generator current prevents further loading of the generator when the current reaches a predetermined value. A return choke GC is provided in the servo system to allow quick return of the arm R to the position of maximum generator field resistance when a master controller MC is moved off the "automatic control " notch 4, whilst a timing choke TC determines the speed at which the arm can move when "automatic control " is operative.

Title: Improvements in or relating to milling machines and tools or jigs therefor
IPC: B23Q1/68
Filed: 1920-05-01
Abstract: 162,538. Guillaume, Ltd., and Mitis, S. J. S. May 1, 1920. Milling-machines. - A horizontalspindle milling-machine for cutting grooves in or flats on small rods such as those used in the production of sewing-machine needles for leather work is provided with a work-holding jig which automatically raises the blanks into contact with the cutters and withdraws them after the operation. The jig comprises a vertical standard h fitted to receive a slide i and having a base secured to the traversing table b which is vertically adjustable by means of a dovetail guide d. A yoke member e, the ends of which carry adjustable stops f<1>, g<1> is bolted to the dovetail guide. The head i' of the slide i carries a turntable n rotatable on a vertical pin r and supporting two bed-plates o, o<1> having longitudinal grooves o<2> in which the blanks are retained by means of spring tongues t and pressure bars v. The arrangement is such that when one set of blanks is positioned beneath the cutters the other set is easily accessible for removing the finished articles and inserting fresh blanks. The two working positions of the turntable are determined by a spring-pressed pin y engaging a groove n<1>. During the movement of the machine table in the direction of the arrow a sliding bar k, Fig. 8, contacts with the stop f<1> whereupon further movement causes the slide i to be raised through a bevelled projection i<1>, thus bringing the blanks on the bed-plate o up to the cutters and causing the bar k to engage the end of a lever l. After a predetermined cutting stroke in the opposite direction the lever l is disengaged by the stop g' and the bar k is shifted by a spring m and the work carrier falls by gravity to its lower position to disengage the cutters from the work. Simaltaneously with the tripping of the lever the traversing gear is thrown out and the machine brought to rest.

Abstract: 568,211. Supply systems for resistance welding. BRISTOL AEROPLANE CO., Ltd.. and ROBERTS, T. M. July 28, 1943, No. 12299. [Class 38 (iv)] To ensure uniform flux waves in the transformer core during successive welds in a spotwelding machine of the kind in which the welding current is supplied by the secondary winding of a transformer having a primary winding fed with pulses of direct current, means are provided whereby, between successive welds, the residual flux is reduced to a constant predetermined value, or is reversed. In the system shown, the direct current pulses are obtained by a bank of condensers 15 which is alternately charged from the supply 14, through pairs of switches 21, 22, and discharged through the primary winding 13 of a transformer 11 through a pair of switches 20. The switches 20, 21 are interlocked so that when one pair is closed the other is open. The secondary winding 12 is connected to welding electrodes 10. Reversal or dissipation of residual flux after discharge of the condensers is effected by switches 28, 30, arranged to open and close in synchronism with the switch 21 and which, when closed, reversely connect the primary winding to the supply through a resistance 27. A switch 23, interlocked with the supply switches 22, short-circuits the primary of the transformer when the latter switches are open.

Abstract: 582,592. Automatic control systems. DEHN, F. B. (Adel Precision Products Corporation). June 29, 1944, No. 12397. [Class 38 (iv)] [Also in Groups XXIX and XXXVIII] Fluid pressure.-In a system for compensat - ing for pressure and volume changes consequent upon temperature changes in a hydraulic installation, variations in pressure control heating means to effect curvature of a diaphragm dividing an accumulator shell into two chambers, one a reservoir chamber connected with the hydraulic system and the other a closed compensating chamber. In Fig. 1, hydraulic accumulators A, forming part of an aircraft hydraulic system which includes a reservoir B, a motor-operated pump C, a control valve D and a hydraulic cylinder E, are each divided by a diaphragm 2 into a reservoir chamber 3 and a compensating chamber 4, the former containing the hydraulic fluid and communicating with a main line G between the control valve and the hydraulic cylinder, and the latter, which is closed, containing a gas or liquid subject to temperature changes by an electric heater 6 supplied from a battery 9 and controlled by a rheostat, 7 which is, in turn, automatically adjusted by a fluid-pressure motor H coupled to the main line G. The arrangement is such that a fluid pressure change, resulting from a temperature change in the hydraulic system which would give rise to a volume change, operates motor H against an adjustable spring 13 to move rheostat 7 and thus alter the temperature, and hence the pressure, in compensating chamber 4 so that diaphragm 2 moves in such a direction as to compensate for the fluid pressure and volume changes. In a modification, Fig. 2 (not shown), the accumulator diaphragm is bimetallic so that its deflection is due both to its own expansion and to the increased pressure of the fluid in the compensating chamber. Use of fluid-operated bellows instead of motor H is referred to.
