Title: Improvements relating to electrical impulse indicating or recording systems
Inventor: DEACON LIONEL OAKLEY
IPC: G08C19/16
Filed: 1949-08-24
Abstract: 686,386. Electric indicating systems. CHAMBERLAIN & HOOKHAM, Ltd., and DEACON, L. O. Nov. 15, 1950 [Aug. 24, 1949], No. 22002/49. Class 40 (i). An impulse averaging and retransmitting system, adapted to the remote measurement of power at generating stations by trains of electrical impulses, comprises an epicyclic mechanism of which one sun member is stepped intermittently in response to the incoming pulses and the other sun member in response to the impulses retransmitted by a motor driven interrupter, so that movements of the planet pinion in response to difference between the sun wheel displacements vary the speed of the interrupter motor so that the impulse 'rate of the retransmitted train is proportionate to the average impulse rate of the received train. In Fig. 1, the input pulses energize an electromagnet a to step a ratchet b geared to a sun pinion e of an epicyclic whose other sun pinion f is geared to a ratchet i stepped by an electromagnet j energized by the output pulses produced in the transmitting circuit n by an interrupter m driven by a variable speed electric motor k. The planet pinion g is carried by a radial arm o on a spindle p freely passing through the epicyclic, to operate a rheostatic phase shifter, or other regulator r controlling the speed of the motor k to maintain the output impulse rate proportional to the average input impulse rate. In a modification (Fig. 2) the spindle d carrying the planet pinion rotates insulated moving contacts 3, 5 between pairs of fixed contacts 4, 6, to control the operation and direction of rotation of a servomotor x regulating a rheostat r controlling the A.C. supply to the winding 8 of the transmitting contact drive motor k, so that as before the output impulse rate is maintained proportional to the average input impulse rate. A further winding 10 energized by the servomotor current through contacts 5, 6, may be used to vary speed of the transmitting motor k, and thus the proportion between output and average input pulse rate, following a load change. In a further modification Fig. 3 (not shown), the planet wheel spindle of the first epicyclic rotates a sun wheel of a second epicyclic, whose other sun wheel is rotated by the servomotor controlling the rheostat in response to the movements of the planet wheel of the second epicyclic.

Title: Engine starter control
IPC: F02N99/00
Filed: 1947-08-08
Abstract: 641,483. Turning-gear. BENDIX AVIATION CORPORATION. Aug. 8, 1947, No. 22133. Convention date, Sept. 4, 1944. [Class 7(v)] [Also in Groups XXXV and XXXVII] In apparatus for controlling the starting motor circuit of an internal-combustion engine having a carburetter 10 provided with a shaft 16 and a throttle 14 the apparatus comprises a switch member 48a slidably movable to open or close the circuit, means, such as a spring 62, yieldingly urging the switch member to its circuit closed position, means, such as throttle lever 24, operable to move the switch member to its circuit open position when the throttle is substantially closed and suction-responsive means such as spring-loaded-piston 70, movable into the path of the switch member in its circuit open position when the engine suction is above a pre-determined value. The switch. (see .also Group XXXVII), is mounted on a boss -28 of .,the carburetter 10 and the switch-member 48a, which protrudes through the gasketclosed end of the switch casing, is capable of conjoint operation with the throttle lever 24. To start the engine, the lever 24 is depressed and the member 48a is permitted to move downwardly, under the actuation of spring 62, since it is in line with a deep annular groove in, the piston 70, to complete the starter circuit. When the engine fires the throttle lever 24 is normally released and moves upwardly taking with it the switch member 48a, thus breaking the starter circuit. When the engine is self-operative, with the carburetter set at idling, the suction behind the throttle is led through channels 86, 88 and 90 to the piston 70, which latter is transversely disposed in an opening in the member 48a, and urges the piston to its rightful limit. The switch member is now prevented from energizing the starter since a shallow groove in piston 70 is engaged by member 48a and irrespective of any further throttle movement the starter circuit cannot be completed until the engine once again stops. If the value of the suction should drop, due to sudden acceleration for example, the switch could not be actuated because the member 48a would move downwardly a short distance under the influence of its spring and frictionally engage some other part of the piston 70.

Abstract: 1425245 Conveying fabric R REICH 9 May 1973 [27 May 1972] 22134/73 Heading B8A Material 2 is transferred from chains 2 of a storage arrangement (F) (Fig. 8, not shown) to chains 4 of an embroidery machine (E) by the action of a transfer wheel 7 (Figs. 2 and 3). The chains 2 and 3 engage the edges of the material by pins 23 carried on bars 22 mounted between spaced parallel chains 3. At the point C (Fig. 2) of transfer between the chains 3 and the wheel 7 pins 9 (Figs. 6 and 7) on heads 11 mounted in housings 8 carried by the wheel 7, are projected outwardly when arriving at the point C. This is brought about by the action of followers 15 on plungers 13 of the heads 11 which engage a fixed cam track 17. The disengagement of the material from the pins 23 is brought about by the action of guide members 25 (illustrated more clearly in Fig. 1, not shown). In a similar way, the pins 9 are retracted at a diametrically opposite point D, so that the material 2 is transferred to the chains 4 by the action of further guide members 25 (Fig. 1, not shown).

Abstract: 806,064. Photo-electric control. OLYMPIA WERKE A.G. Aug. 5, 1955 [Sept. 11, 1954], No. 22605/55. Class 40 (3). [Also in Group XVI] In a pre-feed device for an accounting machine a braking device operates to hold the account card in aligned position with the account as it is inserted when a mark thereon, such as a horizontal stroke, is sensed by a photo-electric cell. The circuits, shown separately are joined at the points a-d. As the account card is inserted its unprinted part reflects the light of a lamp 30 on to a photoelectric cell 29 which becomes conductive and, under the influence of the rectified voltage from a secondary winding 111, causes a voltage drop in a resistor 112 which varies the voltage on a grid of a valve 113 to black it. When a line on the card reduces the intensity of the light reflected on to the cell 29, the voltage on the grid of the valve 113 is varied unblocking it so that current from a secondary winding 115, rectified and smoothed, flows through it and through paper-holding magnets 32a, 32b and a releasing magnet 104, so that the card is held in an aligned position.
