Title: Improvements in or relating to thin magnetic film storage devices
Inventor: JUTZI WILHELM
IPC: H01F10/06
Filed: 1964-09-02
Abstract: 1,076,569. Magnetic information storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 2, 1964 [Sept. 27, 1963], No. 35903/64. Heading H3B. [Also in Division H1] Non-destructive read-out of a thin magnetic film store is achieved by providing a keeper member of magnetic material adjacent each storage cell, effective to return the cell to its original magnetization direction after it has been switched to the hard direction for a time less than the relaxation time constant of the field due to the keeper member. The member comprises soft magnetic material which may be of ferrite or a vapour deposited film and may be isotropic or anisotropic. The relaxation time constant is preferably between 5 and 10 nano-seconds. The member may be in the form of a sheet covering a plane matrix (Fig. 5, not shown) or may form the substrate upon which the film elements are deposited. In the latter case the sheet is provided with a copper coating to act as return conductor for the bit lines (Fig. 7, not shown). Eddy currents induced in the conductive layer tend to assist restoration of the film to its initial state after switching. In other embodiments a separate member is provided for each film and has a similar size and shape to the film. In Fig. 9, store cell 15 and read cell 14 are driven to opposite remanent states by a bit pulse in line B and a word pulse in line W. During read-out eddy currents tend to inhibit switching of store cell 15 so that on removing the read-out pulse cell 14 is restored by the fields due to cell 15 and to the eddy currents in line B. In a modification the sense line and bit line are separate (Fig. 10, not shown), while in a further modification inner and outer bit/sense lines are provided interconnected at one end by an impedance, and connected at the same end to the conductive substrate by a second impedance, while the other end of the outer conductor is connected directly to the substrate. Cells 14 and 15 may exhibit a different coercive force.

Title: Improvements in or relating to conveyors for bricks
Inventor: JONES DAVID
IPC: B28B15/00
Filed: 1955-12-22
Abstract: 799,831. Endless-belt conveyers. SEVENOAKS BRICK WORKS, Ltd. Nov. 5, 1956 [Dec. 22, 1955], No. 36787/55. Glass 78 (1). [Also in Group XL (b)] Brick shapes from a cutting off machine 11, Fig. 1, are carried by an endless belt conveyer 10 to a similar conveyer 12 which transfers them to a conveyer 13. Pneumatically-actuated pushers 16 transfer the bricks one at a time from the conveyer 13 on to a series of conveyers 14 which delivers them to presses 15. Each pusher device comprises a plate 17, Fig. 3, carried by a piston-rod 18 working in a cylinder 19 which can turn about a horizontal axis 20. A stop plate 21 projecting from the plate 17 prevents forward movement of a shape by the conveyer while the plate is moving it transversely thereto. Rollers 22 carried by the pusher run on tracks 24 above the conveyer and towards the end of the outward stroke engage and raise pivoted ramps 26 which, when the rollers have passed, return to the position shown. On the return stroke since the rollers run on the ramps 26 and track 25, the plate 17 is raised clear of the shapes on the conveyer. Selective operation of the pushers is effected by means of a compressed air switch, by electrical or mechanical means, or by photoelectric cells 27 operated upon passage of a selected number of shapes to actuate an electric circuit effecting the operation of the thruster mechanism. The upper run of the belt 13 may be supported by a rigid plate 34. Rollers 33 dipping into oil baths 32 supply a film of oil to the bottoms of the shapes as they pass over them. A gate 35, Figs. 4 and 5, at the end of each conveyer 14 is operated in timed relation with each press 15 to allow shapes to pass one at a time. Each gate 35 is pivoted at 36 and is normally held closed by spring means. A spring-loaded lever 40 is arranged in the path of a reciprocating member 39 forming a part of the press mechanism and co-operates with a member 42 which extends horizontally from the gate. The member 42 has a notch in its underside, which, when it is at rest, is engaged by a stop 43. When the lever 40 commences to turn, it lifts the end of the member 42 to disengage it from the stop. When no shapes are on the conveyer, a feeler 44 drops and the consequent rotation of the shaft 46 causes the arm 47 fast thereon to turn downwards. This movement rocks the lever 49 and the member 42 is raised out of the path of the lever 40. The member 42 on rising engages a stop 53 which prevents any longitudinal movement.

[Also in Divisions G3 and H2] A battery-fed windscreen wiper motor, having armature 16 and field winding 18, is controlled by a relay comprising coil 14 which opens and closes contacts 15 as the current through the coil increases and decreases, an adjustable resistor 13 determining the operating-voltage of the relay. A compensating coil 17 for the relay is load-responsive to modify the setting of the regulator 14, 15 so that the speed of the motor remains substantially constant. Diode 19 is conductive while the contacts 15 are open. In another arrangement, the contacts control the base current of a transistor in series with the motor. In a further embodiment, the circuit elements 13, 14, 16 and 17 are connected in series with an additional resistor, the relay being designed so that, when the load is above a predetermined value, the contacts move between a closed position, in which the additional resistor is short-circuited, and an open position. If the load on the motor is below the predetermined value, the movable contact oscillates between the open position and a third position in which the elements 13, 14 are short-circuited.
