Filed: 1972-03-03
Abstract: 1360752 RF power transistors COMMUNICATIONS TRANSISTOR CORP 3 March 1972 [8 March 1971] 10037/72 Heading H1K Instability of an RF power transistor is avoided by limiting the gain of the transistor to below 13 dB. This is achieved by the insertion of one or more resistors into the base electrode structure and is effective when the transistor is used in either the common emitter mode or the common base mode. The added base resistance also provides protection against excess transistor current caused by a large reflected signal in the collector circuit and which might arise from a broken, touched, or otherwise mismatched aerial connected in the collector circuit. The figure shows a base resistor 21 of nickel-chromium, tantalum, or boron nitride in an electrode structure 8 of aluminium, gold, platinum, or platinum-Silicon. A common resistor 18 is also provided for the plurality of emitter regions 5. In a variant with two or more base main spines from which fingers extend to make individual contact each spine may be provided with a resistor. In another variant the single resistor 21 of the figure is replaced by individual resistors at the base of each finger.

Title: Process of and apparatus for purifying liquids which have been used for washing textile materials
IPC: D06B23/00
Filed: 1932-04-07
Abstract: <PICT:0399826/IV/1> <PICT:0399826/IV/2> In purifying for re-use water which has been used for washing wool or other textiles the water is subjected to a vacuum in order to promote the separation of suspended impurities.  The treatment by vacuum may be preceded by treatment with sodium carbonate or lime or by treatment with acid, sometimes followed by treatment with barium aluminate.  When acid is used alkali is finally added to neutralize.  Such chemical treatment is stated to fix detergent or emulsifying constituents on the suspended impurities. Adsorption of emulsifying constituents by the impurities also takes place if the liquid is allowed to stand for some time or is subjected to mechanical shocks, as by centrifuging.  Suint liquor may, prior to treatment, be raised to a temperature of 100 DEG  C. Hot liquid from a vessel 3, Fig. 2, and acid from a vessel 5 are mixed by baffles 4 as they enter a vessel 6, from which the mixture is drawn through a pipe 7 to a perforated pipe 12, which distributes it in a vessel 8 in which a vacuum is maintained by means of a pump 10.  Light impurities rise and are returned through a pipe 17 to the vessel 6, where they collect as a magma on the surface.  The purified liquid is discharged through a pipe 14.  Steam ejectors 15, 16 assist discharge through the pipes 14, 17 respectively.  A float valve 19 is provided to break the vacuum when the liquid level rises unduly.  The supply of acid from the vessel 5 may be automatically controlled by a device for electrically indicating the hydrogen ion concentration. In the arrangement shown in Fig. 1 the pipe 7 draws cold suint liquor from the lower portion of a washing bowl 22.  Heavy impurities settle in the vessel 8 and are passed to a collector 25.  The purified liquid is returned to the bowl by a pump 24.ALSO:In purifying for re-use water which has been used for washing wool, the water is subjected to a vacuum to promote the separation of suspended impurities.

Abstract: 308,835. Ubslacker, E. March 28, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Driving-gear. - In a swash-plate driving-gear the plate 1 is journaled in a divided abutment 4, which is pivoted on an arm 7. This arm is supported by a foot-step bearing 8, and is secured to the driving shaft 6 to rotate therewith. The swash-plate is connected to the pistons, and is prevented by means of a link from rotating. The explosions in the cylinders tend to move the plate and abutment about the pivot 5, this movement being opposed by the spring 10 and the thrust of the rear axle, when the engine is used on a vehicle. The rear axle thrust is transmitted through the rods 14 to a member 15 on which the spring also bears. This member is connected to a pin 11 in the centre of the abutment by a rod 12. With varying amounts of charge admitted to the cylinders the swash-plate adjusts itself to a varying stroke and compression space. In a modification, a servo-motor is used to adjust the position of the swash-plate.

Title: Improvements in or relating to processes for rendering porous bodies impermeable to liquids
IPC: H01M4/00
Filed: 1925-04-20
Abstract: 235,153. Soc. Anon. le Carbone. June 3, 1924, [Convention date]. Diaphragms; carbon electrodes.-Porous bodies, particularly electrodes of electric cells or electrolyzers are rendered impermeable to liquids by applying an extremely fine powder, such as charcoal powder, and simultaneously or subsequently projecting upon it a violent current of air or gas. The coating so produced is permeable to gases, impermeable to liquids, a good electrical conductor and resistant to chemical action. Fine charcoal powder is made into a paste with resin oil, hot water, or emulsion of water with an equal volume of petroleum or ether or petrol. The resin oil paste is spread on the porous body, which is then baked to carbonize the oil; the body finally being exposed to a strong current of air, which is absorbed. To obtain a superficial coating, the body is dipped for a few seconds in the powder in hot water, or to reach the core it is dipped into the fine powder in the mixture of petrol and water. In each case the body is dried and subjected for a minute to a violent air current. Or the fine powder may be sprayed under pressure on the surface of the electrode, which it may enter on applying a vacuum in the latter.
