Title: A method of making electrodes
IPC: H01M4/34
Filed: 1961-06-30
Abstract: A method of making electrodes for batteries comprises depositing a first layer of monovalent or divalent silver oxide electrode material upon a porous inert form (e.g. a filter paper which may be continuous) from a slurry of the silver oxide in an inert liquid (e.g. water) and withdrawing (e.g. by suction) the inert liquid during deposition, placing one side of a metal (e.g. nickel) grid on the first layer, depositing a second layer of silver oxide material on the other side of the metal grid from a slurry of silver oxide in an inert liquid and withdrawing the inert liquid during deposition, and drying the deposited layer, the amount of electrode material present in the slurry used in depositing the second layer being 2 1/2 -4 times the amount of electrode material present in the slurry used in depositing the first layer.  The layers are compressed and the porous inert form removed from the structure.  The pressed structure is heated to convert the oxide to silver and the structure may be converted into its active form by anodically forming the oxide in situ in the structure.

Title: Improvements in or relating to charge producing devices for internal combustion engines
IPC: F02M21/00
Filed: 1920-08-20
Abstract: 154,560. Good Inventions Co., (Assignees of Good, J.). Nov. 24, 1919, [Convention date]. Vaporizers, external.-The charge is produced by drawing the flame or the combustion products from a variably-controlled suction-actuated burner over a controlled air inlet to produce a hot mixture of air and combustion products, which mixture is then drawn over a fuel inlet. As shown in Fig. 1, the intake pipe comprises sections 14, 19, 20, preferably of increasing size, and is provided with a suction-actuated burner 3, a suction-actuated air valve 15, and a fuel nozzle 16. The burner 3 comprises a fuel nozzle 6, a sparking-plug 12, and a perforated shell 5 through which air, admitted by a suction-actuated valve 13, 'enters to support combustion. The fuel nozzle 6 has a needle-valve controlled fuel outlet, which may be supplied with fuel from the receptacle 11 supplying the nozzle 16, surrounded by a nozzle-shaped casing to which air is admitted. The flame from the burner extends into the section 14 of the intake pipe and mixes with, and heats, the air drawn in through the valve 13 before it mixes with the fuel drawn in through the nozzle 16. The valve 15 may be adjusted so as to supply the whole of the necessary air, but preferably additional air is supplied by a suction-actuated valve 18 adjacent the throttle 2. Hand-operated or throttle-controlled means may be provided to hold the valve 15 closed at starting. In a modification, the beat valves 13, 15, 18 are replaced by slide valves collectively actuated by any suitable means, for example by a bellows or diaphragm operated by suction from a point adjacent the throttle. In a further modification in which the valve 18 is omitted, the valve 15 only is replaced by a slide valve. In the form shown in Fig. 6, the burner casing 35 is perforated to admit air directly from the atmosphere, the perforations being protected by a hood or casing 36, and the fuel pipe 40 is supplied from a well 38 extending below the level of the fuel reservoir 11 and connected to it through a restricted passage regulated by a screw 39. Air enters the top of the well through a regulated opening 42 and the pipe 40 is provided with a hole 41. The fuel accumulated in the well 38 furnishes a rich mixture at starting, after which the fuel level falls to about the level of the hole 41,through which air is then sucked to mix with the fuel ascending the pipe. The sections 14, 19 of the intake pipe may be arranged as a coil. The burner may be cut out after starting, or may be used to supply unignited mixture.

Title: Improvements relating to amplifying devices for use in wireless telegraphy and telephony
IPC: H03D11/02
Filed: 1919-10-06
Abstract: 156,330. Bolitho, J. B. Oct. 6, 1919. Thermionic amplifiers and detectors.-In a " trigger " relay, oscillations initiated by incoming signals are periodically quenched by a second valve which intermittently neutralizes the reaction between the grid and anode circuits of the triggered " valve. In the arrangement shown, the potential of the grid 2 of the " trigger " valve is brought to the required value by means of the battery 10 and potentiometer 11, and impulses induced in the grid reaction coil 9. from the coil 33 in the signal circuit, raise the potential of the grid 2 sufficiently to cause the valve 1, 2, 3 to oscillate. A condenser 34 mav be shunted across the coil 9 to tune the circuit 34, 9 to incoming signals. A second valve 12, 13, 14 is employed to neutralize periodically the reaction between the grid and anode circuits of the valve 1, 2, 3 by means of a coil 22 having a reversed reaction and included in the plate circuit of the valve 12, 13, 14. The filaments 3, 14 are connected in parallel, whilst the grids 2, 13 are joined with or without arrangements for applying a different potential to the grid 13 as compared with the grid 2. An oscillating potential is applied to the plate 12 by coupling the plate circuit to an oscillating valve circuit 23. When the potential of the plate 12 -becomes sufficiently positive, a current flows through the coil 22, the reaction of which balances out the reaction of the coil 4. The oscillations initiated in the valve 1, 2, 3 by incoming signals are thus intermittently damped out at a frequency equal to the frequency of the oscillations produced by the source 23, which should be low compared with that of the incoming signal. An indicating or recording device 7 is included in the plate circuit of the first valve. Any source of oscillations cr impulses may be used in place of the oscillating valve 23.

Abstract: 1527676 De-excitation of dynamo-electric machines URANIT URAN ISOTOPENTRENNUNGS GmbH 15 June 1976 [5 July 1975] 24649/76 Heading H2A Apparatus including a hysteresis motor 1 fed from a three phase supply through a rectifier 3 and inverter 4, there being a capacitor 6 connected to the D.C. circuit between the rectifier and inverter, which capacitor discharges through the inverter when the rectifier output is interrupted, also includes a circuit for automatically increasing the output frequency of the inverter while the capacitor discharges whereby the hysteresis motor is de-excited. This avoids the possibly harmful effects of self-excitation when the apparatus is switched off. Under normal operating conditions the switching frequency of inverter 4 is determined by a voltage-frequency converter 17. When the voltage at the input to rectifier 3 drops, e.g. on de-energization, a voltage monitor 9 causes a relay 11 to connect an auxiliary voltage source 13 to the converter 17 which then increases the switching frequency of the inverter, e.g. by about 10%.
