Title: A process for producing chlorine and sulphate from alkali chlorides
IPC: C01B7/03
Filed: 1925-12-22
Abstract: 249,474. Zellstofffabrik Waldhof, and Schmidt, E. March 21. 1925, [Convention date]. Chlorine. - Chlorine and alkali sulphate are produced from alkali chloride by the action thereon of sulphur trioxide mixed with air, the temperature being such that melting of the chloride does not take place and the gas evolved does not contain sulphur dioxide. Suitable gases are those produced from oleum, the temperature of the reaction with the alkali chloride being between 300‹ F. and 600‹ C. A lower temperature may be employed if contact materials are present. Gases from contact sulphuric acid furnaces, containing 7 per cent of sulphur trioxide, may be conveyed through several chambers containing briquettes of common salt. The reaction is started by a supply of heat, the heat of reaction afterwards being sufficient to maintain the temperature. The salt chambers are so arranged that the freshest chambers come into reaction with the weakest trioxide gas. Alternatively, a revolving tubular kiln may be employed. Specifications 1908/71 and 15152/99 are referred to.

IPC: G05D1/08
Filed: 1949-12-17
Abstract: 681,382. Automatic control of helicopters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 18, 1950. [Dec. 17, 1949] No. 32427/49. Class 4. Gyroscopic apparatus for stabilising a rotary wing aircraft in pitch or roll comprises two rate gyroscopes having different natural frequencies about their pivotal axes when undamped and for different relative damping and having each a single gimbal which is spring retrained about its pivotal axis so that its deflection is proportional to the rate of change of altitude of the aircraft about that or a parallel pitch or roll axis and which are damped in proportion to their speed of deflection, and means whereby a particular combination of the deflections of the gyroscopes is transmitted to the normal pitch or roll controls, the arrangements being such that substantially that particular control displacement proportional both to the amount of change of attitude and rate of change of attitude is provided, the inherent error of the one gyroscope which would involve the acceptance of a compromise if a single gyroscope were used being compensated by the other gyroscope and vice versa. The figure shows the arrangement for pitch control of the machine, the two gyroscope rotors 20, 21 being mounted in brackets 14, 15 to have a single degree of freedom only about fore-and-aft axes 16, 17 respectively. Deflection of the rotors about the axes 16, 17 is restrained by pairs of springs 22, 23 and 24, 25 in order that such deflection may be proportional to rate of aircraft displacement, while their deflection is also damped in proportion to the speed of deflection by dashpots 26, 27. The springs 22 ... 25 are such or so adjusted that in the absence of the dashpots 26, 27 the natural frequencies of oscillation of the rotors about the axes 16, 17 are different, and the dashpots 26, 27 are such or so adjusted that the relative dampings (the ratio of the actual damping to initial damping) also are different. Arms 28, 29 extending from the frames 18, 19 are connected by links 30, 31 to a lever 32, which in turn is connected to a thrust rod 12 operating a servo motor 11 for actuating the aircraft pitch controls. The desired damping of the pitch oscillation of the aircraft is obtained by appropriate adjustment of the relative lengths of the arms of the lever 32, and of the springs 22 ... 25 and dashpots 26, 27. A similar arrangement is employed for damping roll oscillations, the pivotal axes of the gyroscopes being disposed transversely of the aircraft.

Filed: 1960-09-22
Abstract: 964,325. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Sept. 22, 1960 [Sept. 29, 1959], No. 32604/60. Heading H1K. A device exhibiting a negative resistance region in its forward characteristic comprises a semi-conductor body of one conductivity type with two spaced regions of the opposite conductivity type forming PN junctions therewith, one of which has the characteristics of a tunnel diode and the other of which rectifies in the opposite sense to a conventional PN junction. A typical device is made from a 0.001 ohm cm. N-type silicon wafer. After etching in a mix of concentrated nitric and hydrofluoric acids and rinsing successively in de-ionized water and methyl alcohol the wafer is placed on a tantalum strip heater with the ends of wires 14, 15 pressed lightly against it, heated for 4 seconds in helium at above the eutectic temperatures of the wires and silicon, and then cooled rapidly in a blast of compressed air. Wire 14 of aluminium is 5 mils in diameter and is spaced 20 mils from the end of a 3.5 diameter wire 15 of aluminium-boron alloy (containing 0.75% by weight boron). Due to the high solubility of boron in solid silicon the recrystallized zone 13 is more heavily acceptor doped than zone 12 and, because of the rapid cooling, forms with the bulk of the body a PN junction exhibiting tunnel effect. The other junction rectifies in the opposite sense to conventional PN junctions. The device has a V-I characteristic basically similar to that of a tunnel diode but has a much higher reverse impedance. An additional control electrode may be provided to the wafer 11 if desired. Specification 923,339 is referred to.

Filed: 1952-12-30
Abstract: 745,740. Extruding. KREIDLER, A. Dec. 30, 1952 [Dec. 31, 1951], No. 32924/52. Class 83 (4). [Also in Group V] An elongated body having portions of different cross-section and in which the rear part at least is hollow, is made by extruding a billet successively through dies of different cross-sections, the hollow portion being formed by a mandrel. A solid billet 9 is first pierced by a mandrel 8 and simultaneously a portion of the billet is extruded through a die 4. The latter is then replaced by a die with a larger orifice and the remainder of the billet is extruded as a tube between this orifice and the mandrel by a ram 7. In another embodiment, Fig. 9, a hollow cylindrical billet 15 is extruded between a mandrel 23 and a pair of dies 17, 18 with different sized orifices. The dies are held in position by removable stops such as 21 slidable in guideways 27. Each stop carries a cam 28 co-operating with a spring-loaded slide 32 which, during the initial part of the extrusion process, holds the stop 21 in engagement with the die 18. At a predetermined point in the process, arms 37 on the press ram 22 engage the slides 32 and thus release the stops 21 whereby the die 18 is then carried loosely by the smaller portion 14 of the extruded body whilst the remainder of the billet is extruded through the die 17 only. In a modification the slides 32 are actuated by solenoids controlled by a switch engaged by the portion 14 of the extruded body. The slides may alternatively be released by hydraulic or pneumatic means.
