Patent GB-362640-A (GB)
Abstract: 362,640. Coin-freed apparatus. HYMAN REGISTER CORPORATION, 405, Walbridge Building, Buffalo, New York, and HYMAN, D. N., 837, Pingree Avenue, Detroit, Michigan, both in U.S.A. Nov. 17, 1930, No. 34593. [Class 27.] Registering.-In means having a coin slot and register, a member pivotally supported adjacent the slot is swung on insertion of a coin, and register-operating means carried by the member is moved laterally to the plane of swing of the member into position to operate the register. The fare box and register comprises a box 1 provided with a door 2 and window 4 through which may be seen a series of vertical coin receiving perforated tubes 5 open at the upper end to receive coins inserted through slots 6. A receptacle 7 fitted with a slide 8 is provided for each tube. A single slide 12 operated by a rod 13 serves for discharging the coins from the tubes into the receptacles. Each slot 6 is provided with a coin-registering mechanism 14 visible through an opening in the top of the casing and worked by a crank 15. When a coin is inserted in the slot, the edge engages a roller 21 on a frame 17 pivoted on a shaft 18 around which is a spring tending to keep the frame in the position shown in Fig. 5. A guard plate 31 lies across the slot when the frame is turned into the position shown in Fig. 6. Mounted on the frame is a rod 27 having a limited turning movement about its axis and bent so as to form a hammer arm 28 carrying a head 29 adapted to strike a bell 16. The lateral bend 30 is engaged by the coin and the shaft 27 turned against its spring 34 from a position normally out of alignment with the bell into the plane of the latter. When the axis of the coin passes a horizontal line through the roller 21 it is released by the fingers and the spring acts to return the frame 17 the part 30 being guided over the face of the coin to swing the stop 31 and roller 21 out from beneath the coin. The end of the rod 27 away from the slot is bent to form an operating arm 32 the end 33 of which when the frame 17 is swung towards the bell, strikes the pin 38 on the arm 15 of the counter to turn it and register one unit. The sounding of the bell occurs simultaneously. If the coin is not fully inserted, but withdrawn, the spring 34 will bring the members 29, 33 out of alignment with the bell and register and the frame 17 is returned. An abutment plate 35 adjacent the bell is engaged on one face or other by the portion 33 or arm 32 according to whether the device is approaching the top of the box in operative or inoperative condition and guides the mechanism after the coin has fallen. On insertion of a further coin, the mechanism is moved clear of the guide 35 before the coin engages the part 30 whereupon the spring 34 returns the parts to the inoperative positions. A fixed arm 41 is provided with stops to limit the movement of the crank 15 in both directions. A slotted link 36 in which the crank pin 38 engages is pivoted to the frame 17 and serves to draw down the crank for operation on the return of the frame. This link may be dispensed with and a spring fitted to the crank.

Title: Anode films for dry cells
IPC: H01M50/489
Filed: 1955-12-19
Abstract: A film of methyl cellulose is made by forming a layer or film of an aqueous solution of a water-soluble methyl cellulose and coagulating the layer or film by contacting it with an aqueous solution of a chloride or sulphate of ammonium or of a metal more electropositive than zinc, or of zinc sulphate, or of mixtures of such sulphates or chlorides.  The methyl cellulose layer is preferably formed from an aqueous solution containing 8-14 per cent, desirably 10 per cent, of an ether having a viscosity (measured as a 2 per cent solution at 20 DEG  C.) of at least 1000 centipoises, preferably 4000 centipoises. The coagulant solution may contain 10-40 per cent, preferably at least 15 per cent, of the coagulant, and the coagulation may be performed by immersing the ether layer in the coagulating solution, by extruding a solution of the ether into the coagulant solution, or by causing a layer of a solution of the ether to flow on a support and then contacting this layer with the coagulant, the coagulation process being suitably performed at 0-45 DEG  C.  Plasticizers and softeners may be added to the coagulating solution if desired.  The films so prepared contain a substantial amount of residual coagulating agent and are useful as anode films in dry cells (see Group XXXVI).  A mercury compound, e.g. mercuric chloride, may be added to the methyl cellulose, before or after coagulation, to facilitate amalgamation of the anode.  Specification 603,927 is referred to.
