Title: Improvements in or relating to information storage devices
IPC: G11C11/42
Filed: 1957-03-04
Abstract: 856,930. Coating by vapour deposition. SOC D'ELECTRONIQUE ET D'AUTOMATISME S.A. March 4, 1957, No. 7080/57. Class 82(2) [Also in Groups XXXVI and XL(a)] An information storage element comprises an electroluminescent and visible-light luminescent layer 1 and a photoresistive layer 2 between a pair of translucent electrodes 3 and 4. The material of the luminescent layer 1 can be a complex of oxides and/or sulphides, e.g. zinc oxide actuated by samarium oxide. The material of the photo-resistive layer 2 can be silicon, germanium or tin oxide or antimony oxide. The electrodes 3 and 4 can be film deposits of aluminium. In making the storage element a film of aluminium is formed by an evaporation process in vacuum on a plate of high melting point glass and a plate bearing a coating of antimony is placed opposite the film. The coating of antimony can be formed by evaporation into the plate in a vacuum of, e.g. 10-4 mms., from crucibles arranged at the four apices of a virtual surface parallel to the plate. An oxygen atmosphere is established under a constant low pressure and a D.C. voltage applied across the antimony-supporting plate and the aluminium film to form a layer of antimony oxide on the aluminium film. The antimony-coated plate is replaced by a plate coated as above described with an alloy of zinc and 1% samarium and the discharge process repeated to form on the layer ofantimony oxide a layer of zinc oxide activated by samarium oxide. A further aluminium film is evaporated on to this layer. A raster generator is made by depositing on a supporting plate, of a high melting' point dielectric material, such as glass, ceramics or enamelled metal. a network of conductors by a serigraphy process (through a silk screen) by painting with a mixture of pulverulent silver and enamel of low melting point in an essential, oil, and heating the plate in a H.F. induction oven. The conductors are then thickened by a rhodium deposition and optically polished. A layer of luminescent material comprising zinc oxide and 1% of copper oxide is formed over the network by the process previously described. A further conductor network is deposited on the luminescent layer by evaporating thereon a continuous film of aluminium and photo-etching the film.

Title: Improvements in or relating to variable speed transmission gear
Filed: 1941-06-13
Abstract: 550,046. Variable-speed gearing. GUY, S. S., and BULLOCK, W.E. June 13, 1941, Nos. 7461 and 7463. [Class 80 (ii)] In motor vehicle transmission gearing having a clutch 4 between the engine 2 and the speed gearing 3, a servo-motor 5 acting through a rod 10 and lever 9 continually tends to disengage the clutch 4 but is prevented from so doing by a fluid pressure servo-motor 6 supplied with pressure fluid through a pipe 8. A lever 11 is interconnected with the speed change lever 12 so that when the latter is moved to change gear the lever 11 actuates a valve 7 which disconnects the servomotor 6 from the pressure pipe 8 and connects it to an exhaust pipe 8a whereupon the servomotor 5 acts to disengage the clutch 4. A tail clutch in a casing 13 may be connected to the lever 9 by links 14, 15, 16 so that it is disengaged simultaneously with the clutch 4. The servomotor 5 is actuated from the engine intake manifold or from other source of negative pressure.

Inventor: MCKEOWN CHARLES GEORGE
IPC: C21D9/663
Filed: 1954-03-16
Abstract: 760,614. Circulating furnace atmospheres. CONTROLLED HEAT & AIR, Ltd. March 14, 1955 [March 16, 1954], No. 7561/54. Class 51 (2). A coil annealing furnace, particularly of the type disclosed in Specification 723,821, has a centrifugal fan e with blades curved or inclined relative to a radius to the axis of rotation of the fan to give a greater impelling action in the forward direction than in the reverse. During the initial heating and final cooling of the coils c the fan is rotated in reverse, but is rotated forwardly during the soaking period. The fan is mounted within a housing e<SP>1</SP> open at the periphery and having star or radial diffusion plates for the equal delivery of the atmosphere gas to the circumference of the lining. The change in direction of rotation of the fan is achieved automatically by means of a time or thermostatically actuated switch in the circuit to an electric motor driving the fan, this switch having means associated therewith to provide a time lag permitting the fan to come to rest before starting it in the opposite direction.
Patent GB-609336-A (GB)
Title: Improvements in or relating to record controlled statistical machines
Filed: 1946-03-11
Abstract: 609,336. Statistical apparatus. BROUGHAM, L. E., and PERRIN, J. March 11, 1946, No. 7573. [Class 106 (i)]. Apparatus for transmitting data read from a record to the parts of a machine to be controlled thereby, comprises a plurality of intermediate elements between the sensing means and the data transmitting elements, means for connecting any one of the intermediate elements to co-operate with any one of the index point positions on the record, and means operative under the control of testing means to actuate data transmitting elements corresponding to the intermediate elements which are in responsive condition. The upper ends of connection wires 11, Fig. 1, from the sensing pin box pass through a conducting plate 12 and, when operated, are pushed between two-bladed contacts 13, Fig. 8. One blade of each contact is connected to a common conductor 15, while the others terminate in plugs 17 at a plugboard 16, the sockets of which are connected to contacts 14, Fig. 1. Immediately after the card has been sensed, a carriage 20 is moved to the left by cam means and a contact blade 21 moves across the contacts 14, Fig. 8, until a circuit is completed to an electromagnet 23, one of which is associated with each column. The energized magnet 23, Fig. 1, pulls down its armature 47 together with a spring-urged plunger 50, Fig. 3, which is attached to one of a series of horizontal bars 44 mounted for parallel motion. The depression of a bar 44 at the moment when the contact strip 21 reaches a live contact 14, rocks a bar 39 causing a selecting finger 35 to engage and lift a corresponding intermediate pin 27. Pivoted to each pin 27 is a latch 31 having a shoulder 28 supporting a spring-urged pin 26 so that the lower end of the latch is pressed against a bar 29, one of which is provided for each row of pins 27. The pin 27 is thus lifted until the lower end of the latch 31 is freed from the bar 29 and snaps over its upper edge. Also moving with the carriage 20 are two cam bars 32 having wedgeshaped ends 33, Fig. 1, arranged to co-operate with similar recesses in the bars 29. As the carriage moves, the cam bars 32 force the bars 29 upwards, and where operation of the selecting finger 35 has latched a pin 27, this is forced upwards also to set the corresponding stop 36 in the stop basket. The common conductor 15, Fig. 8, is normally connected with a contact 14a, Fig. 1, which energizes the associated magnet 23 when the selecting finger 35 is under the first pin 27a, and the upward movement of this pin operates a member 36a in the stop basket which releases the typecarrying sector for that column as described in Specification 454,857. Arranged in one of the supply lines to the conducting plates 12, a second contact blade 66, Figs. 1 and 8, moves in synchronism with the first, over shorter contacts, to prevent sparking at the contacts 14. The contact blades 21 and 66 are arranged to be lifted clear during the return movement of the carriage 20. Also, a condenser 70 and spark quenchers 72 are connected in the circuit.
