Title: Deferred action electric battery
IPC: H01M6/38
Filed: 1959-07-28
Abstract: 861,805. Batteries. ELECTRIC STORAGE BATTERY CO. July 28, 1959 [Sept. 12, 1958], No. 25827/59. Class 53. A reservoir for storing the electrolyte of a deferred-action battery comprises concave and convex walls 16, 18 and a diaphragm 17 between them, all three members being joined together round their peripheries 19. The wall 16 is connected by a bushing 22 to a manifold 12 leading through openings 13 to the battery cells. The space between the wall 16 and diaphragm 17, which holds the electrolyte is sealed from the manifold by a frangible disc 23 which can be ruptured by a knife 24 when the battery is to be filled. The knife is attached to a rod 25 fixed to the diaphragm and which carries a piston 26 in a fixed bushing 27 which also encloses an electrically-operated squib 29. The apparatus can be operated in either of two ways according as the battery is under vacuum or atmospheric pressure. In the first case the squib when fired exerts sufficient pressure to depress the knife and cause it to disrupt the disc 23. Atmospheric. pressure acting through openings 33 in the wall 18 then forces the diaphragm 17 downwards, thus ejecting the electrolyte into the manifold 12. In the second method the squib ejects sufficient gas under pressure to press the diaphragm into its lowest position. The openings 33 are not provided in this case. A baffle 14 equalizes the flow of electrolyte into the various battery cells.

Abstract: 656,753. Jointing by rolling; binding and covering. SUPERIOR STEEL CORPORATION. Oct. 8, 1948, No. 26272. Convention date, Nov. 12, 1947. [Classes 83 (ii) and 83 (iv)] Making compound sheets.-In a machine for peening together the parts of bimetallic billets and the like, the work is supported and guided by adjustably spaced sets of opposed rollers. In peening facing-pieces 3, Fig. 8, of stainless steel, copper, gilding metal, cupronickel and the like to flanged backing members 2 of carbon steel or the like the work is guided to the peening rolls 4, Fig. 1, over stepped rolls 16 carried by a pair of supports 19 which may be adjusted for width across transverse slides 18 by oppositely threaded screws 20 and are locked in position by bolts 23. The rolls 16 support the lower facing piece 3 on the smaller stepped portions 24 and guide it be. tween the edges of the intermediate portions 25 while the backing member 2 is supported by the portions 25 and guided by the edges of the larger portions 26. The backing members 2 pass to the rolls 16 between side guides 30 adjustably pivoted about axes 31 and locked by bolts 34 to conform with the width of the rolls. The work is further advanced by resiliently supported conical pinch rolls 36, Fig. 9, on vertical intergeared shafts 37, supported by pivoted bearings 38 which accommodate the outward movement of the rolls 36 as the work enters between them, while the teeth of the gears 41 are shaped to permit relative angular movement. As the work advances it is brought to rest by a hydraulically-operated stop 28 which serves to position the pieces endwise. In operation, a facing piece 3 is placed by hand on the rolls 16 against the stop 28 while a backing member 2 is fed by a pair of walking beams 9 from a roller bed 7 to a second roller bed 11 in line with the peening machine along which it is pushed to the side guides 30 and pinching rolls 36 by a hydraulic ram 12. An upper facing piece 3 is then placed by hand on the member 2, the stop 28 is withdrawn and the work fed to the peening rollers 4 by a ram 48 having a vertically projecting pusher arm 43 which engages the work. The arm 43 is pivoted at its base and yieldingly retained in the vertical position by a spring 44 which permits the arm to be forced downwards as the work passes over it when fed to the rollers 16. The peening rolls 4 may be may be rotated positively or by the passage of the work through the rolls.

Abstract: 264,906. Creed & Co., Ltd., Creed, F. G., and Salmon, R. D. Oct. 22, 1925. Type-printing telegraphs.-Relates to a continuously-running transmitter controlled by a strip perforated according to a multiple unit code and of the kind in which the position of a single switch member, movable between contacts, is controlled successively by the signal units by the motor operation of cams acting in cyclic order upon members of which the movements 'are transmitted or not to the switch member according to the position of corresponding peckers cooperating with the strip perforations. The cams act directly on levers which move the switch member and to which the peckers are pivoted. The drawings illustrate a transmitter operated by a strip perforated according to a five-unit code with start and stop signals such as would be produced by the apparatus described in Specification 264,907. The switch member comprises a spring blade 4, Fig. 1, moving between contacts 2 and 3, and carried by a rocking member 6 controlled by a spring 7. The free end of the member 6 extends across the ends of six levers 8 each controlled by a spring 9 to hold a roller 8<a> carried by the lever against a corresponding cam a - - f, Fig. 7, on a shaft 18 driven through gears 15, 19 from the main driving spindle. The five peckers 10 are each pivoted to one of the levers 8, the sixth lever, associated with the cam f, carrying no pecker and serving to send to line an impulse for starting the start-stop shaft at the receiving station. The free ends of the peckers are held by light springs 28 against guiding grooves on the spindle 27 of the tape feed wheel which is driven through gearing from the shaft 18. The cams a - - comprise six precisely similar discs, Fig. 9, each provided with an edge flat 11 and three circularly-arranged holes 11<a>. The discs are assembled with spacing washers 13, Fig. 7, in six different angular positions on a sleeve 12, mounted on the shaft 18, and are connected by a pin 14 passing through a hole 11<a> in each disc, three positions being obtained by using three different holes in discs arranged with one face foremost, and the other three positions by using three different holes in the remaining discs which are reversely arranged. The pin 14 is fixed in the gear wheel 15 rigid with the sleeve 12 and in a washer 16 secured to the sleeve as by a pin 17. The cam unit is secured to the shaft 18 by the engagement of an extension 17<a> of the pin 17' in an open-ended slot 22<a> in the shaft and by a screw 23 engaging a threaded hole 22, in the shaft. The pecker mechanism and the mounting of the electrical connections may be as described in Specification 191,772.

Filed: 1961-07-21
Abstract: A method for securing connector end-pieces to a sintered rod of one or more carbides, borides or nitrides of Ti, Zr, V, Ta, Nb or Hf comprises wetting a portion of the sintered rod with liquid aluminium, the wetted portion then being placed in contact with a molten metal or alloy having a melting point of at least 950  DEG C., said metal being at least partially miscible with Al in the liquid state (e.g. Ag, Cu, Fe, Ni or their alloys).  The Al coating may be applied by immersing the rod as a cathode in a cryolite/alumina electrolytic cell. The Al coated end-pieces may be lowered into a crucible of the molten metal which is allowed to cool to form an ingot, which may be machined to size, on the end of the rod.  The rod is used as the cathode in the electrolysis of cryolite/alumina to produce aluminium.
