Title: Improvements in apparatus for registering the time of opening or closing of receptacles for tickets and the like
IPC: G07C1/32
Filed: 1922-04-10
Abstract: 199,531. Birtwhistle, H. April 10, 1922. Time checking apparatus, check and token.-Apparatus for registering the time of opening or closing of receptacles for tickets &c. comprises a casing 1, between which and a metal strip 4 is held a bag 3. Part of the opening at the top of the bag is closed by a loose plate 13, adjacent to which is a transverse partition 14. The casing has hinged to it a lid 2 having attached to its underside a stop-watch 7, and when the lid is closed an aperture 6 therein registers with the opening 34 at the top of the bag. This aperture is normally masked by a slide 17 which is held back against springs 21 bv the screen 24 and nut 22 so that tickets may be dropped into the bag. The stop-watch is started when the lid is closed and when the slide 17 is released by turning the screw 24 it masks the openings 6, 34 and seals the apparatus by reason of spring-pressed pins 27, now engaging in recesses 32 in the lid. At the same time a pin 18 fixed on slide 17 and passing through a slot in the plate 14 acts upon the stoplever 12 of the watch. The screw 24 may be operated mechanically from the alarum mechanism of an alarum clock and the pin 18 may start the watch 7 instead of stopping it.

Abstract: 549,718. Electric cables; electroplating. STANDARD TELEPHONES & CABLES, Ltd. Aug. 11, 1941, No. 10176. Convention date, Sept. 13, 1940. [Classes 36 and 41] An electric cable is formed by extruding a lead sheath over a cable core, immediately brass plating said sheath, and extruding and vulcanizing a covering of vulcanizable material thereover. The lead sheath is applied to the conductor core 24 by an extrusion press 6, and is then cooled as by spraying with water &c. in a tank 17. The cable then passes through one or more electroplating tanks 12 to which the solution is continuously supplied by pumps 13 from an overflow tank 14. The tanks 12 contain brass electrodes 10 forming anodes, and the cable forms a cathode to which electrical contact is made by grooved rollers 16. The plating solution may comprise 6.5 to 7.5 ounces of copper cyanide, .9 to 1.1 ounces of zinc cyanide, and 3 to 5 ounces of free sodium cyanide per gallon, with sufficient sodium hydroxide to give a pH value between 10.6 and 11.3, giving a brass plate of about 75 per cent copper and 25 per cent zinc ; if the temperature of the cable is above 100‹ F., more zinc cyanide is used. The cable may then be passed through a water rinsing and drying apparatus before winding on a reel 15. A rubber coating may then be applied as by the extrusion and vulcanizing apparatus described in U.S.A Specification 1,689,206.

Abstract: 527,243. Iron manufacture. KELLOGG CO., M. W. April 4, 1939; No. 10557. Convention date, April 18, 1938. [Class 72] [Also in Group III] In a continuous process for the generation of hydrogen water is reacted in the liquid phase with a finely divided metal, especially iron, at temperatures between 450‹F. and 700‹F, and at a pressure above the corresponding vapour pressure of water, the gaseous product being continuously removed and water continuously added, fresh metal being supplied to the reaction zone and spent oxide removed therefrom. The iron employed may be in the form of porous pellets containing a metal low in the electromotive series. Thallium salts may be added to the water to facilitate the reaction. In the apparatus shown the iron pellets are supplied from a hopper 1 through a valved outlet to charging vessels 6, 7 which communicate through valved passages with reaction vessels 24-27 into which preheated water is introduced through pipes 47-50. The hydrogen generated passes off through pipe 38 whence there is a connection 24 to allow establishment of pressure in the vessels 6, 7. The hydrogen is passed through a heat exchanger 39 and condenser 40 from which the condensed water is returned by way of a pump 43 and heating coil 46 to the reaction vessels. The spent oxide is withdrawn through vessels 51, 52 and a hopper 68 all provided with valved inlet and outlet passages, and is removed from the hopper 68 by a conveyer 69 to a reduction furnace whence it is subjected to the action of a reducing gas such as a mixture of hydrogen and carbon monoxide. In the arrangement shown natural gas and air are preheated and supplied through pipes 77, 78 to a space below a brick chequer work 79 in the furnace above which are mounted vibrating screens 81 on to which the spent oxide is discharged and where it is reduced by the products of the partial combustion of the natural gas. The regenerated iron is discharged through a duct 82 and is returned by conveyers to the hopper 1.

Title: Improvements in telephone substation circuits of the anti-side-tone type
IPC: H04M1/58
Filed: 1944-06-02
Abstract: 591,495. Anti-side-tone circuits. WESTERN ELECTRIC CO., Inc. June 2, 1944, No. 10687. Convention date, Oct. 24, 1942. [Class 40 (iv)] In a substation circuit of the anti-side-tone type, the impedance of the balancing means is changed in accordance with the direct current flowing in the line, so that the balance is automatically adjusted for lines of differing lengths. The variation in impedance may be by a non-linear resistance variable by applied voltage or by heating. In the arrangement shown in Fig. 3, the non-linear resistance 60, comprising two parallel opposed copper oxide elements, is connected across the balancing arm X, C1 and the value of X is chosen to balance a line of maximum anticipated length. If a shorter line is connected to terminals L1, L2, the direct current flowing is greater and this causes the resistance of V to decrease to a point where the combination of X and V again balances the line. Fig. 4 shows an arrangement in which the direct current from the line L1, L2 is passed through a heating coil H, the variation in whose temperature affects the sensitive resistances E1, E2. Various other arrangements are described giving the selective insertion or cutting out of inductive or capacitive branches instead of a simple resistance. Suggested varistors are copper oxide and silicon carbide and suggested thermistors are silver sulphide, uranium oxide and mixtures of metallic oxides.

Title: A process for the production of pure alkali fluorides
Filed: 1930-04-04
Abstract: Solutions of potassium and other alkali metal fluorides containing thionates, obtained for instance from potassium sulphide by the action thereon of a simple or complex hydrofluoric acid, are purified by treatment with acids or acid salts under conditions which prevent dissociation or which do not allow it to become active in aqueous solution.  The added acid is not then bound by liberated alkali and the thionates are decomposed.  In carrying out the process the fluorides, after an addition of hydrofluoric acid or acid fluoride equivalent to the thionates present, may be heated to temperatures of about 300 DEG  C.  After cooling the fluoride may be extracted with water to free it from precipitated sulphur.  Alternatively sufficient hydrofluoric acid may be added to form the acid salt and provide some excess, whereby the thionates are decomposed directly.  From the purified bifluoride after separation of precipitated sulphur hydrofluoric acid and pure alkali fluoride may be obtained by heating say to 400 DEG  C.
