Title: Improvements in or relating to intrinsic safety igniting devices for electronic flash-units
IPC: H05B41/32
Filed: 1959-05-01
Abstract: 863,298. Photographic cameras combined with flash-lamps. CHARBONNAGES DE FRANCE. May 1, 1959 [June 20, 1958], No. 15009/59. Class 98(1) [Also in Group XXXV] An electronic photographic flash unit of the type wherein a capacitor 11 is charged from a transistor power unit 1-9 through a rectifier system 13-15, the ignition system comprises a transformer 20, the primary winding 20p of which is supplied with a series of pulses from the power unit amplified by a power transistor 19, which is switched by a second transistor 26 controlled by a synchronizing switch 24 which may be in the camera. A capacitor 25 when fully charged through transistor 19 prevents any appreciable flow of energy into the primary winding of transformer 20. When the switch 24 is closed, the transistor 26 shunts the capacitor 25 causing a succession of amplified pulses to be passed to an ignition electrode 21 on the flash tube 12. The switch 24 may be replaced by a germanium photo diode when simultaneous ignition of several tubes is required. A neon lamp 18 may be connected across the capacitor 18 to indicate when the capacitor 18 is sufficiently charged, a resistor and capacitor 17 preferably being connected in series and shunt respectively. The circuit is stated to be intrinsically safe.

Title: Improvements in or relating to the manufacture of electrical capacitors
IPC: H01G4/32
Filed: 1962-04-18
Abstract: 1,000,247. Capacitors. EASTMAN KODAK CO. April 18, 1962 [April 27, 1961], No. 15086/62. Heading H1M. In a method of making a capacitor, films 11 made of non-heatset planar molecularly orientated linear poly-(1,4-cyclo-hexanedimethylene isophthalate - terephthalate) are wound with interleaving metal foils 13, e.g. aluminium, the capacitor being subsequently heated to set and shrink the films without disturbing their planar molecular orientation. Terminals 15 are inserted when the capacitor is being wound and extra turns of the films 11 are added to form a cover. During heat-treatment the capacitor contracts to the form shown in Fig. 4, the films being fused together to form seals where they extend beyond the edges 22 of the foils. The dielectric constant of the films may be increased by applying a unidirectional p.d. across the electrodes formed by the foils while the capacitor undergoes heat-treatment, the p.d. being the rated voltage of the capacitor. The period of heat-treatment is 0.5 to 15 minutes at a temperature above the " heat-distortion " temperature and below the " no-strength " temperature of the material from which the films are made, e.g. 140‹ to 235‹ C.

Filed: 1974-04-10
Abstract: 1471769 Regulating speed of articles in an endless conveyer system METAL BOX Ltd 3 April 1975 [10 April 1974] 15802/74 Heading B8 Articles 9 passing from conveyer belts 26 to a pusher conveyer 11, have their speeds adjusted while on the belts 26 so that they arrive in synchronism with the pushers 18 of the conveyer 11. As shown, there are two auxiliary conveyers 29 and 32 supplementing the belts 26. The conveyer 29 runs at a faster speed than that of the belts 26 and conveyers 11 and 32. The conveyer 32 carries rollers 37 arranged at a spacing which is slightly greater than the length of each article 9. Thus in operation, when each article 9 is received on the belts 26, 26, it is squeezed between the belt 45 of the conveyer 29, and a roller 37 of the conveyer 32 (unless it happens to fit immediately in the space between two adjacent rollers 37). Due to the faster speed of the belt 45 and the free running of the roller 37, the article is accelerated into the space, between the roller 37 which was engaged and the next roller 37 downstream. Prior to being fed on to the belts 26, 26, the article is conveyed by a decelerating conveyer 20, and an accelerating conveyer 22. A conveyer 15 extends from a packaging machine (not shown), and the conveyer 11 feeds to a closing and sealing machine (not shown). In modifications, the conveyer 22 may be omitted, or may be replaced by decelerating surfaces; the conveyor 22 may be omitted; a backing rail 44 for the rollers 37 may be omitted; the belts 26 may be replaced by a dead plate; the conveyers 32 and 29 may be disposed respectively, beneath and above the articles 9; the conveyer 29 may be replaced by a dead plate, or by a conveyer which moves more slowly than, instead of faster than, the belts 26; the pitch of the rollers 37 may be smaller than the pitch of the dogs 18; the belt 32 may be driven at a slower speed than that of the conveyer 11; some or all of the sprockets 19, 21, 30, 31, 33 or 34, may be laterally movable against limiting stops, under the bias of resilient means; and the rollers 37 may be replaced by projecting ears having an antifriction surface.

Abstract: 119,868. Angus, A. R. Oct. 10, 1917, [Convention date]. Electrical systems, non - automatic; track apparatus actuating signals on trains and for stopping trains; signalling to and communicating between trains and cabins and stations.-Signals or train stopping apparatus tending constantly to come into operation, but restrained from so doing by electro-magnets adapted to be energized by electricity of one or other direction or frequency received from apparatus on the track, provided that the apparatus on the train is set in one of its different positions in accordance with the direction of travel of the train so as to bring into use apparatus adapted to be energized by current of the direction or frequency supplied to the track apparatus. Fig. 1 shows apparatus on the track for supplying currents of reverse polarity or no current to the track rails in insulated sections from a common battery 12 under control of a manually operated three-position switch 6. The armatures of the polarized relays 26, 14, &c. serve to connect the insulated rails 2, 3, 4 to the line wire 13, 15, 17, so that opposite track rails of each section are connected to opposite poles of the battery according to the position of the switch 6. Instead of this arrangement different sources of alternating current of different frequency may be substituted for the battery 6. The trains are equipped with apparatus controlled by a polarized relay 230, Fig. 3, or by two alternating current relays responsive only to one frequency; in either case the controlling relay is energized by connexions through slip rings 233, 227 connected to certain wheels 200 so as to be in shunt to the train axles 201. The contacts of the relav 230 are in series with contacts 215, 220, 225 of a switch, which is moved by connexions to the reversing gear 350 of the locomotive, and with the magnet 212 and battery 210.
