Title: An improved electric generator or gas battery
IPC: H01M8/14
Filed: 1926-03-04
Abstract: 271,581. Kendall, J. A., and Gore, R. E. March 4, 1926. Gas batteries. - A gas battery comprises a number of gas cells arranged in a chamber, the cells being supplied with hydrogen or water gas in sufficient quantity to enable the chamber to be kept at a red heat by the combustion of the gas. Fig. 4 shows a single gas cell consisting of two concentric tubes a, c made of porous metal such as porous silver, copper, nickel, cobalt or iron, to which conducting leads f, g are secured. The space between the tubes is filled with a refractory substance b such as magnesia, oxide of cerium or a mixture, of magnesia and oxide of iron, nickel or cerium; barium carbonate may also be added.. This filling is saturated with a fused saline material such as the carbonate or borate of an alkali metal. The lower portions d, e of the tubes a, c may be made of non-porous metal. A nickel rod or tube i may be placed within the tube a to cause the gas passing through the tube to come into close contact with its inner surface. When the outer tube c is made of silver it may be surrounded by silver wire netting. The porous metal tubes may be made by moulding a mixture of the powdered metal and its oxide or a reducible salt and heating it in a current of hydrogen. Metal wire or gauze may be embedded in the mixture. Porous copper tubes may be made by mixing copper powder, obtained by reducing cuprous chloride by zinc, with water and cuprous chloride or other reducible salt of copper such as the oxalate. The paste is moulded into the form of a tube and heated to redness in a current of hydrogen. Porous nickel tubes may be produced in a similar way. A small quantity of cobalt is preferably added to the nickel. When the tubes are made of cobalt a small quantity of silver is preferably added. Silver tubes may be made by applying a thin coating of porous silver to the surface of the earthen tube b. This may be done by covering the tube b with a paste of oxide of silver and heating to redness. Fig. 6 shows a complete battery consisting of a number of cells c in a chamber p to which hydrogen or water gas can be supplied through a tube q. The cells are set in a floor k which is made of refractory earth such as magnesia, containing borate of lime which has been strongly heated. The gas admitted through the tube q is ignited at the top of the cells and when the interior of the chamber gets red hot a current is obtained at the terminals t of the battery. The draught in the chamber can be varied bv a sliding chimney w having perforations w<1> and by sliding dampers. Air holes v<1> are also provided between the cover v and walls of the chamber.

Patent GB-971113-A (GB)
Title: Improvements relating to impact fuzes for projectiles
IPC: F42C15/188
Filed: 1961-02-20
Abstract: 971,113. Ammunition fuzes. INVENTA A.G. FUR FORSCHUNG UND PATENTVERWERTUNG. Feb. 20, 1961 [Feb. 18, 1960], No. 6179/61. Heading F3A. A projectile percussion fuze comprises a rotatable cylinder 3 which depending on its angular position renders the fuze safe prior to arming, armed or permanently safe. The cylinder 3 is normally locked by a device comprising a bolt 13, spring 15 and a ball 16 which engages in a groove 24 in the cylinder. On launching, the bolt 13 sets back to allow ball 16 to roll out of groove 24, thereby freeing cylinder 3. However, at the same time a tube 17 around a striker 19 also sets backs and enters a bore 11 locking the cylinder and pushing a sleeve 10 to the bottom of the bore where it protrudes into an annular groove 12 in the cylinder 3. When the acceleration of the projectile ceases the tube 17 is moved forwardly by a spring 18 out of bore 11 so that cylinder 3 is then free to rotate clockwise under the action of a spring 4. Rotation continues until sleeve 10 encounters a stop 8 which projects from the body of the fuze into the groove 12, Fig. 3. In this position a primer 5, which via a bore 7 communicates with a relay 6, lies along the longitudinal axis 23 of the fuze, i.e. in the path of the striker 19. According to the invention, should the cylinder 3 be released before launching takes place, rotation thereof occurs until a stop 9 projecting from the cylinder into groove 12 encounters stop 8, Fig. 4. Accidental release of cylinder 3 before launching occurs without displacement of sleeve 10 due to inertial movement of tube 17. In this condition the fuze remains permanently inactive. The invention may be applied to electrical impact operation and a braking system is described to retard the rotation of cylinder 3.

Title: Improvements in or relating to heating gases and vapours
Inventor: MACCORMAC MICHAEL
IPC: F28D17/04
Filed: 1956-03-02
Abstract: 818,894. Apparatus for producing combustible gases. GAS COUNCIL, and POWER-GAS CORPORATION Ltd. Feb. 22, 1957 [March 2, 1956], No. 6667/56. Classes 55 (1) and 55 (2). A cyclic process for heating gases or vapours to a high temperature employs two separate beds of heat storage material. The gases or vapours may be carbon dioxide or steam for use in endothermic reactions involving carbonaceous material, carbon, or hydrocarbons or may be water gas or steam which is passed through retorts in which coal is carbonized. In the first phase of the cycle, air is forced by blower 27 through conduit 28, valve 32, and connection 32a into a regenerator 1 where it may be heated to 600‹ C. The preheated air passes through valve 9 and conduit 10 to meet gaseous or liquid fuel entering through connection 39a, and the products of combustion pass through regenerator 5, valve 15, conduit 13 and waste heat boiler 42, to the stack. The waste heat boiler may be by-passed by conduit 45. After a purge period in which gas or vapour entering at 34a removes the products of combustion from regenerator 5 through regenerator 1 and valve 14 to the stack, the second phase is commenced by passing gas or vapour upwardly through regenerator 5 and conduit 11 to the reactor 47. Products of reaction pass through cooler 48 and valve 20 to use. At the same time, valve 9 being closed, blower 27 passes air through conduit 29 and valve 31 to combust gaseous or liquid fuel entering regenerator 1 at 38a. The products of combustion pass through regenerator 1, valve 14, and conduit 13 to the stack. The reaction with the highly heated gas or vapour may take place in the empty space 7, above the heat storage material 6 in regenerator 5, by injecting the reactant through connection 41a. The products of reaction are then passed through conduits 11, 17 to wash box 50 and onwards through valve 26 and conduit 25. If the reaction in space 7 is between steam and oil to produce oil gas, the same oil being used to heat the regenerators, the connection 41a may be omitted. Valve 9 may be water-cooled or it may be replaced by a refractory damper. In this case a butterfly valve in the stack connection of regenerator 1 is so controlled automatically that the differential pressure across the refractory damper is substantially zero. Specification 740,482 is referred to.

Abstract: 873,634. Controlling aircraft. BELL AEROSPACE CORPORATION. March 3, 1958, No. 6692/58. Class 4. Aircraft control means comprises a movable aerofoil hinged to the aircraft structure by a hinge including relatively rotatable parts having an interior connected to a source of gas under pressure and having ports arranged so that on movement ot the aerofoil from neutral position, the ports are opened differentially to discharge gas into the atmosphere to provide a jet reaction force. The figures show an aircraft tailplane 12 with elevators 14 each attached by a clevis 24 to an outer cylinder 22 rotatably mounted on an inner cylinder 20 attached at 26 to a fixed branch duct 28 of a main duct 30 in the aircraft, connected to a compressor driven by the aircraft engine. Ports 32, 34 in the inner cylinder, and 36, 38 in the outer cylinder co-operate so that when theelevators are in neutral position, the two discharge streams from the ports of each pair of cylinders produce equal and opposite pitching moments, but on movement of the elevators to give an aerodynamic pitching moment, the ports are opened differentially to produce a jet reaction moment in the same sense. The cylinders 20, 22 form the only hinge for the elevators. The jet reaction pitching moment is most useful near stalling speed or in low density atmosphere, and a valve 45 may be operated to eliminate the jet reaction moments at the pilot's discretion. Similar devices may be embodied in aileron and rudder controls. Specification 873,635 is referred to.
