Abstract: 1,013,241. Semi-permanent stores. STANDARD TELEPHONES & CABLES Ltd. April 17, 1964 [April 19, 1963], No. 15476/63. Heading G4A. [Also in Division H4] A semi-permanent associative static data store responds to input search data and produces corresponding output data by optoelectronic means. The embodiment described is suitable for use as a translator in an automatic telephone exchange. The store described is a matrix array, each row, Fig. 3, comprising n storage locations at each of which is located a pair of photo-conductive cells 3A1, 3B1 connected in parallel, all the pairs of cells of the row being series connected to a set of electroluminescent elements 3C1, one for each storage position, and which are connected in parallel. Associated with each row is a mask, Fig. 2, carrying " address " data and corresponding " output " data (in effect, the same information in two different codes) in the form of a hole such as 2A1 at a first position associated with the first cell 3A1 of a storage pair location to represent a binary " 0 " and a hole such as 2BC2 at a second position associated with the second photo-cell 3B1 to represent a binary " 1." All holes at the " 1 " position are enlarged to permit transmission of light from the electroluminescent element in the corresponding storage location. In operation, the required address data is set up by illuminating appropriate ones of pairs 1A1, 1B1 of electroluminescent elements in the " address " part of a register, Fig. 1, the remaining locations in the register, Fig. 3, having both electroluminescent elements illuminated in each location. The arrangement is such that only in the matrix row which stores the required " address," will at least one of each pair of photo-cells 3A1, 3B1, be illuminated, thereby closing a series path to the parallel-connected electroluminescent elements 3C1 &c. of that row, which elements therefore transmit light via the mask in that row, the data stored in the mask being received by photo-cells in the register, Fig. 1, in accordance with the required output data. The light sources may alternatively be light-emitting PN junctions, and the light-sensitive elements may alternatively be photo-transistors.

Abstract: 900,205. Electric vaporizers. FLETCHER, R. J. Oct. 15, 1958 [July 15, 1957], No. 15514/57. Class 39 (3). [Also in Group II] Metals, e.g. aluminium, are evaporated in a vacuum by contact with a graphite or carbon filament 1 secured in electrodes 2 cooled by a circulation in pipe 3. In Fig. 5 a tubular graphite or carbon filament 10 has a watercooled shield 12 and a side opening 11 for introduction of the metal wire 13 and for escape of the metal vapour. The hollow retains any slag, the melted wire rising up the inside of the tube to the opening 11 where it evaporates. The wire metal 13 may be substituted by block metal introduced at the ends. The filament 10 may contain a refractory metal, e.g. tungsten, tantalum or zirconium in the form of a bundle of wires or sheet or powder. The bottom of the filament 10 may be pierced by small holes. Al-bronze at a high temperature may be fed to a molten pool of aluminium in the filament to ensure instant evaporation. To evaporate zinc a graphite filament is first wetted with molten copper with or without prior treatment with aluminium. The zinc is fed into the copper pool with which it alloys and then evaporates. A carbon or refractory scraper may scrape the filament. The filament may be oscillated or rotated, supported in an aluminium trough where a hopper 18 supplies the metal under the surface of the molten pool. In Fig. 10 a web of paper or other sheet material is metallized under vacuum. The heating filament 22 is mounted in electrodes 23 supported by insulating blocks 24 in a water-cooled shield 25. The metal wire 26 to be evaporated is fed to the filament. Angularly adjustable water-cooled shields 27 concentrate the heat of the filament and determine the area of open space through which the evaporated metal may pass. The paper &c. web comes from a supply roller 29 and is coated and received on a roller 30. In Fig. 15, graphite connectors 39 holding the filament 38 are seated in ceramic insulators 40 and held by clamps 41 which may be cooled.

Abstract: 199,399. Fonck, R. P., and Wibault, M. H. M. J. June 19, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Steering and balancing.-The ailerons of an aeroplane &c. are so connected up to the controls that the outer aileron only is depressed and the inner one is immobilized during a turn. Means also may be provided for permitting opposite . movements of the ailerons, or for depressing both ailerons simultaneously. Fig. 2 shows a camplate b pivoted at a<1> and moved by a lever a. Two levers e<1>, e<2> pivoted at e are connected to the ailerons and have rollers d<1>, d<2> which normally rest in the ends of a circular slot c having its centre at a'. When the plate b is displaced, the roller d<1> or d<2> moves in an eccentric slot c<1> or c<2>, thereby depressing the corresponding aileron, the other roller remaining in the circular slot c. The cam-plate b may be combined with another cam permitting ordinary movements of the ailerons. Fig. 4 shows mechanism for effecting alternatively the unilateral or simultaneous depression of the ailerons. Two overlapping cam-plates b<1>, b<2> each similar to one half of the plate b, Fig. 2, are pivoted about a tube a' which has trunnions to take the sleeves a <2> on the forked end of the lever a. Two sleeves g also are mounted on these trunnions, the sleeves having toothed quadrants g<3> gearing with similar quadrants i<1> on the plates b<1>, b<2>. Lugs g<1> are formed on the sleeves g and shorter lugs a<4> on the sleeves a<2>, both lugs being slotted at a<5> to take transverse bolts h which can be moved by the pilot backwards and forwards parallel to the axis of the tube a<3>. When the bolts h are to the left of the slots a<5> the sleeves a<2>, g are locked together so that a forward movement of the lever a will move both cam-plates b<1>, b<2> and depress both ailerons. The inner ends of the bolts h are guided during this motion by slots f<2> in plates f fixed to the tube a<3>. When the bolts h are to the right of the slots a<5> their inner ends engage slots f<1> in the plates f thereby locking the lugs g<1> to the plate f. Simultaneously a latch, not shown, locks the two plates b<1>, b<2> together. Lateral movement of the lever a then effects unilateral movement, of the ailerons.

[Also in Division G3] A hydro-pneumatic system for applying a band brake 15 of an epicyclic gear-box consists of a spring-loaded, pedal-operated lever 2 actuating a plunger 5 which displaces hydraulic medium in a cylinder 4 to move a plunger 6 which causes a mechanical-pneumatic transducer 7 to produce a pressure in a conduit 9 to cause actuation of a piston in a cylinder 10 connected to a lever 12 which operates the brake, movement of the lever causing a piston and cylinder device 14, 13 to withdraw liquid from the space between the plungers 5, 6. The pressure in the conduit 9 reacts through the transducer on the plunger 6 so that the force exerted on the brake is proportional to that applied to the pedal. A release catch 20 is operated by the pedal. In a modification a fixed end wall to the cylinder 4 takes the place of the plunger 6 and the transducer is operated by the piston 14.
