IPC: H01M4/73
Filed: 1956-02-07
Abstract: 803,488. Making battery plates; extruding. CROMPTON PARKINSON, Ltd. March 6, 1957 [Feb. 7, 1956], No. 3834/56. Classes 83 (2) and 83 (4). In a method of forming a plate for a lead-acid secondary cell or battery, a supporting grid is prepared by punching holes in an extruded sheet of lead or lead alloy foil. Lead or lead alloy is extruded by a press 1 having a ram 2, to form a tube 4 which is split continuously by a blade 5 and flattened by rollers 6. The flat sheet or foil so produced which may be ribbed or plain is perforated by punches 8, the holes so formed acting as a key for a paste subsequently applied at 9. Finally the pasted sheet or foil is cut into individual plates 12 by a blade 11. Alternatively flat lead sheet or foil, either ribbed or plain may be directly extruded from a press prior to the punching operation. Further, two flat sheets so extruded may be dealt with simultaneously. When cylindrical battery elements are required two continuous pasted strips with separators between are rolled up to form the element.

Title: Cathode ray tube circuits
IPC: H04N3/20
Filed: 1941-03-21
Abstract: 546,507. Cathode-ray oscillographs. PHILCO RADIO & TELEVISION CORPORATION. March 21, 1941, No. 3898. Convention date, March 21, 1940. [Class 37] [Also in Group XL] Cathode-ray tubes energized by rectifiers are provided with a condenser which is charged when the circuit is in operation and is so arranged that, when the rectifier is switched off, voltage is applied from the condenser to an electrode of the cathode-ray tube to stop or reduce the electron beam to prevent damage to the screen. As shown in Fig. 1, when the main switch 13 is closed, switch 27 is also closed, working bias is applied to the cathode of the cathode-ray tube through the potentiometer 28, 15, and the condenser 24 is charged to a high potential determined by the ratio of the resistance 25 to the resistance 26 plus the part of the resistance 15 in series with it to earth. When the switch 13 is turned off, the switch 27 is also turned off and the voltage from the condenser 24 is then imparted to the cathode of the cathode-ray tube with the result that the electron beam ceases. The other parts of the circuit of Fig. 1 are substantially as usual for a television receiver. In a modification, Fig. 2, also showing a television receiver, the switch 13 is coupled to a switch 41. The cathode potential is determined by cathode potentiometer 42, 40 of valve 2. When the switch 41 is closed, the resistance 40 which is high is shunted by the resistance 35 which is low, the latter resistance bay shunted by a condenser 37 to by-pass A.C. components. When the switches are turned off, the voltage on the condenser 39 is applied to the cathode of cathoderay tube, which is then separated from earth by the high resistance 40.

Title: Improvements in or relating to expansible link straps
IPC: A44C5/08
Filed: 1951-02-19
Abstract: 699,917. Making chain bracelets. KIEFER, E., [trading as KIEFER, E, [Firm of]]. Feb. 19, 1951 [Oct. 4, 1948], No. 3936/51. Class 83 (ii). [Also in Group VII] An expansible bracelet or metal link strap, e.g. of the kind used for the attachment of a wristwatch, consists of a series of interengaged units each comprising a rectangular plate 2, Fig. 37, with trough-shaped pockets 3 along its longitudinal edges to receive projections 7 at one end of a flat slidable connecting sleeve and similar projections 8 at the correspondingly opposite end of the next adjacent sleeve, as shown in Fig. 36. Within each sleeve member there is located a slidable cross-piece 16 with projecting ends 17 which engage within the longitudinal pockets 3 of the unit within which it is mounted, and a tapered lug 18, either integral with or secured to the cross-piece 16, forms a mount and support for a spring 15 arranged so that it is compressed when the bracelet is expanded. In making the bracelet a flat sheet-metal blank 2, Fig. 1, with end portions 1 of greater breadth is first pressed into a double crank shape, Fig. 4, and the ends 1 are next pressed or swaged to form troughshaped pockets 3, Fig. 6, having closed ends. In order to turn the openings of the pockets towards each other the middle part of the plate 2 is bent or buckled upwardly, Fig. 8, and then straightened as in Fig. 10. Since it is necessary that the edges of the pockets should be exactly parallel in order to guide the flattened sleeve members, they may be milled longitudinally to ensure parallelism. The flat sleeve members may be made from a single punched piece or stamping 6, Fig. 23, with lateral tabs 12, 13 which are shaped into end trunnions after folding the end portions of the blank inwardly along transverse medial lines between the tabs of the respective pairs 12, and 13, a completed sleeve with end trunnions 7, 8 being shown in Fig. 37.

Title: Improvements in or relating to toys
IPC: A63H3/31
Filed: 1964-01-30
Abstract: 1,017,315. Mechanical toys. M. GLASS [trading as MANN GLASS & ASSOCIATES]. Jan. 30, 1964 [Feb. 4, 1963], No. 4021/64. Heading A6S. A toy figure, e.g. a bird, is supported on converging, rotatable, legs 25 (Fig. 5, not shown) having substantially circular feet 45, which legs are driven by an electric motor via a gear train. The toy waddles along a substantially straight path until "attacked" i.e. by having its tail pulled, whereupon it turns on its "attacker" and simultaneously produces raucous noises. Pulling on the tail causes a bar 147 (Figs. 6 and 8, not shown) to move forwardly against action of a leaf spring, which bar effects raising comb 17 (Fig. 1, not shown), and opening the lower jaw. Movement of the bar also effects anti-clockwise movement of a spring urged rocker 145 (Fig. 7), disengagement of clutch 68, and reversal of current flow to the motor. Upon reversal of the current the motion of the cogs in the gear train is reversed and compound gear 95 which is swingable about the shaft of compound gear 91 swings in an anticlockwise direction (Fig. 7) and engages an idler cog 115. The rotation of the leg adjacent cog 115 remains the same whilst the motion of the other leg is reversed thus the legs move in the same direction and the toy turns around. During turning of the toy a lug 167 of the rocker 145 follows the outer surface of the clutch 171, but upon engagement with the groove 169 the switch is returned to its first position and the toy again describes forward motion. During waddling movement a piston member 249 forces air through a resonating chamber 233 to produce a whistling sound, the pitch of which is varied by a second piston 261 which alters the effective length of the chamber 233. Upon reversal of the motor, the compound gear 95 swings anticlockwise and engages an abutment of a pivoted spring actuated arm 247, plug 245 is therefore removed from a bypass opening 243 of the chamber 233 and at the same time spring 277 contacts a cog wheel 101 thus to produce by vibration raucous sounds in a hollow resonating box 267. After resumption of waddling movement the raucous noise is stopped by depressing the comb 17 which action causes the vertical plate 287 which has legs astride the arm 247 to move that arm clockwise to disengage the spring 277 from the cog 101. Waddling is produced by two cog wheels 97, 99 which have staggered teeth, so that during drive of one leg the other leg will not be driven. Lever 173 when actuated anticlockwise operates the switch 53 to prevent current flow to the motor 49. In an alternative embodiment (Figs. 13, 14 not shown) the drive motor is controlled by a switch which is actuated by a comb. Reversal of the switch simply causes the toy to move in the opposite direction.

Parachutes.-In parachutes of the kind described in Specification 21312/14, means are provided for restricting the opening of the parachute until it has fallen clear of the aircraft from which it is launched. In the form shown in Figs. 1 and 2, the restricting-means comprises cords 10 connected to the rigging 3 and to a container 2, so that the spreading of the parachute is restricted by the cords 10, as shown in Fig. 2, until they become taut and break under the stress of the load. In modifications, the restriction is under the control of the pilot; for example, tongues 14, Figs. 3 and 4, attached to the periphery of the parachute 13 are lightly secured together by stripping pieces 15 connected to a cord 17 leading to the pilot; or a series of tapes may connect the periphery of the parachute to a central releasing- device under the control of the pilot. In order to prevent the sensation of a dead drop, frills 52, Fig. 14, may be attached to the rigging and a small parachute 54 may be added. Further, an auxiliary parachute 55 may be provided as described in Specification 105,944. Specifications 24594/14 and 8649/15 also are referred to.

Filed: 1941-03-28
Abstract: 546,764. Silver-antimony alloy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 28, 1941, No. 4212. Convention date, March 28, 1940. [Class 82 (i)] [Also in Group XL] A photo electric cathode which is irresponsive to red and infra-red rays is obtained by forming a film of a silver-antimony alloy on a glass support and then depositing a caesium layer on the alloy. The alloy contains from 17 per cent. to 13 per cent. antimony and the layers are thin enough to transmit 30 per cent. to 53 per cent. incident light or the alloy layer may be opaque and form a mosaic. The cµsium is applied without prior oxidation of the alloy but a small amount of oxygen may be applied to the layer for a very short time, to improve the action of the cathode in its colour response. As applied to an image intensifier the photo cathode is formed on a glass wall W of the tube by (1) vaporizing alloy pellets 7 by means of a filament 6 and (2) vaporizing cµsium pellets 9 from the side tube 8. Lens elements 2, 3, 4 and an anode 5 direct the electron image on the fluorescent screen S ; a gap 14 in the element 4 allows the caesium to flow freely from the side tube. Specification 488,920, [Group XL], is referred to.
