Title: Improvements in or relating to electric motor controllers
IPC: B66C13/24
Filed: 1943-07-01
Abstract: 567,508. Control of D.C. motors. IGRANIC ELECTRIC CO., Ltd. July 1, 1943, No. 10685. Convention date, July 16, 1942. [Class 38 (iii)] Control apparatus for a hoist motor MI, particularly one supplied by a Diesel-driven generator, comprises (1) a master controller MS having means selectively to establish power connections for hoisting, or power and dynamic braking connections for lowering, and to afford speed control ; and (2) regulating means to render substantially uniform under heavy and light loads a high lowering speed selectable by the master controller and to interrupt the power connections at certain lowering speeds when the motor is being overhauled by the load and tending to return current to the generator. The regulating means comprises a reverse-current relay ICR which carries the armature current of the motor when the controller MS is in the lowering positions and which drops out to de-energize the operating.coil of a line switch 1KO when the armature current reverses due to overhauling. When the relay is closed and the controller moved to its final lowering position 5, an electromagnetic switch IA, which is closed in all the other positions of the controller, is energized and opens a short-circuit on a section R1 of field resistance to provide a high lowering speed for an empty hook or light load. The system shown embodies the features described in Specification 557,582, and, with switches H, M closed, provides for the series connection of the armature A, field F, brake winding B and resistors R2-R6 in the hoisting positions of the controller, the resistors being cut out sequentially by switches 2A-6A, preferably subject to time control, as the controller is moved through positions 1-5. Switch 2DB is closed only when the controller is in the off position, thus establishing a dynamic braking loop which excludes resistances Rl-R4 and brake coil B, switches 5A, 6A then being under the control of a relay VR for graduation of the braking effect as the motor comes to rest. Current may be diverted from the armature by closure of switch 1KO in the first and second hoisting positions to provide for slow speed hoisting. Movement of the controller to the lowering positions closes switches 1KO and IDB and opens H, thus connecting the armature and field in parallel, the field circuit including the resistors R4-Rl which are sequentially inserted with progressive movement of the controller, R1 being subject to the over-riding control of relay ICR.

Title: Improvements in or relating to shift registers
IPC: G11C19/08
Filed: 1968-03-06
Abstract: 1,206,241. Shift registers. SIEMENS A.G. 6 March, 1968 [6 March, 1967], No. 10780/68. Heading G4C. [Also in Division H3] A shift register comprises two rows of anisotropic magnetic thin film stages 1, 3, 5 and 2, 4 . . . , Fig. 1, with each film coupled to the next stage in the adjacent row by an output conductor 11, a Hall voltage being produced in the output conductor by passing a read current pulse through the film. The magnetic thin film stages of a row are connected in series with a respective read conductor 10, and read pulses IOI,IOII, Fig. 3, are applied alternately to the two read conductors. Each read pulse rotates the magnetizations of the films through which it passes towards the hard direction of magnetization, and so generates a Hall voltage in each associated output conductor which sets the next stage films in the adjacent row to corresponding magnetic states. Setting of the next stage films in the row adjacent to that energized by a read pulse is aided by pulsing a bias line 12, the field produced augmenting a standing magnetic bias which acts in the hard direction of magnetization. Due to the standing magnetic bias, the remanent magnetization of the films is inclined by approximately 45 degrees to the hard direction, Fig. 2, the direction of inclination depending on the digit stored.

Title: Improvements in and relating to article feeding devices
IPC: H01J9/24
Filed: 1954-04-13
Abstract: 747,148. Endless conveyers. BRITISH THOMSON-HOUSTON CO., Ltd. April 13, 1954 [April 16, 1953], No. 10866/54. Class 78 (1). In a feeding device comprising two parallel endless belts 3 arranged to carry articles, e.g. electric lamp bulbs 1, with two diametrically opposite points thereof riding on the belts to a receiving station, a support 33 is provided at the delivery end to receive in a rest position an article leaving the belts, the support being so shaped and arranged that the article in the rest position is at a slightly lower level than when riding on the belts. As shown, the belts 3 run on the horizontal flanges of angle girders 11 which have lateral guides 21 secured to them, the angle girders together with further angle girders 12 supporting the lower runs being secured at one end to frames 15 mounted on a common base 16 and at the other end on the frame of a processing machine to which the bulbs are to be delivered. The support 33 at the delivery end is U-shaped and is secured to a cross-member 14 which also carries a lower stop member 36 having forwardly converging arms 38 embracing the stem of a bulb being deposited in rest position on the support 33, the belts 3 which frictionally engage the bulb on support 33 urging the bulb stem against arms 38. The bulb is thus held in a predetermined attitude for transfer by a reciprocating carrier (Fig. 1, not shown) to the processing machine. To prevent following bulbs from disturbing the bulb on support 33 and to keep them spaced sufficiently to prevent excessive tilting a pair of lifting- plates 39 is carried on links 40, 47 of unequal length from the framework so that upon movement of the links plates 39 move upwardly and rearwardly from a slightly downwardly and forwardly inclined position just below the belts 3 to a raised horizontal position above belts 3. Extensions 49 of links 47 are interconnected by a bar 50 acted on by the piston-rod 51 of an air cylinder 52 to raise plates 39 whenever air is supplied to the cylinder through a valve 54 electrically controlled by a feeler switch 56 adapted to be closed by a bulb on the support 33. In operation, the arrival of a bulb on support 33 causes plates 39 to be moved upwardly and rearwardly so that the following bulbs are lifted off belts 3 from the rear and so are spaced. Upon removal of the bulb on support 33 switch 56 opens, cutting off the air supply and exhausting cylinder 52 so that springs 53 may cause plates 39 to move to their lower position, redepositing the following bulbs on belts 3 from the front so further spacing them. Specification 746,668. [Group XVI], is referred to.

Title: Vehicle door latches
IPC: E05B65/32
Filed: 1962-03-23
Abstract: 938,450. Latches. GENERAL MOTORS CORPORATION. March 23, 1962 [April 7, 1961], No. 11155/62. Class 44. A vehicle door latch comprises a pivoted bolt having two toggle links 68, 70 hinged together at a knee joint 72 and movable to an unlatched position, in which the knee joint is bent, against the tension of a spring 74, a swingable operator lever 96 which, via a transmission link 110 trips the bolt 68, 70 to said unlatched position upon the operation of a push-knob 28 on the outside of the door, and a locking trip-lever 120 having a coupling link 122 mounted thereon which couples the transmission link 110 to the operator lever 96 when the trip lever 120 is in unlocking position and uncouples said transmission link 110 when the trip lever 120 is in locking position. In the " unlocked " position the trip lever 120 occupies a clockwise position, as viewed in Figs. 3 and 12. In this position a coupling link 122 pivoted on trip lever 120 at 124 is held in an upper position so that a projection 126 on link 122, extending through gap 114 in transmission link 110 and through the gap 104 in operator lever 96, couples them positively together so that when the operator lever is moved clockwise, as viewed in Figs. 3 and 12, by the knob 28, the projection 112 on transmission link 110 strikes the projection 84 on the toggle link 68, and withdraws the lower toggle link 70 from the latch block 76, Fig. 1. In the " locked " position of trip lever 120, i.e. counterclockwise position, the projection 126 of link 122 projects into the lower part 106 of operator lever 96 and therefore does not lock link 110 to it. Movement of operator lever 96 thus does not trip the toggle link 68. Should, however, the door be closed when in " locked " condition, the toggle links still move as a solid member, and through the medium of a projection 86, and a member 128 coupled through a spring 130 to trip lever 120, move said trip lever to the " unlocked " position. Downward movement of a knob 52, Fig. 1, will similarly restore the trip lever 120 to the " unlocked " position.
