Title: Improvements relating to Unipolar Semiconductor Devices
Inventor: DRANGEID KARSTEN E
IPC: H01L29/00
Filed: 1968-08-15
Abstract: 1,172,783. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 15 Aug., 1968 [22 Aug., 1967], No. 39070/68. Heading H1K. A field-effect device is made by depositing layers successively of insulation, metal, and insulation on a substrate, forming a slot through the layers to the substrate and depositing semiconductor in the slot to form a conducting channel controllable by application of voltage to the metal (gate) layer. Typically, the substrate is of N-type silicon or gallium arsenide and forms one electrode of the device though a metal layer beneath the other layers may alternatively serve this purpose. Silica is a suitable material for the insulating layers and molybdenum or tungsten, which form a Schottky contact with silicon used as the semiconductor may be used for the intervening gate layer. The layers are formed by cathode sputtering or evaporation and the slot, which may separate the gate into two independent parts, by photo-etching. Contact to the upper end of the channel is made by cathode sputtering a gold-antimony compound or aluminium and etching to shape. In an alternative MOS device, the slot is lined with insulation prior to depositing the channel material. In either case additional gates may be provided by depositing further layers of metal and insulation and the frequency of response improved by extending the source and drain electrodes to form input and output transmission lines. A number of devices with a common source or drain may be formed on the same substrate.

Title: Improvements in or relating to agents for the treatment of textiles
IPC: D06M13/252
Filed: 1930-12-31
Abstract: Raw, spun, or woven textile materials are softened or delustered by treating them with alkali xanthogenates derived from alcohols or alcohol mixtures corresponding to soap-forming aliphatic or naphthenic acids having more than six carbon atoms in their molecules.  The xanthogenates are obtained by treating the alkali alcoholates (or mixtures of alcohols and caustic alkali) with carbon disulphide.  They may be employed together with fat solvents, impregnating agents, and other materials used in the treatment of textiles, and may be subsequently decomposed on the fibre, with reformation of the alcohols, by treatment with dilute solutions of acids or acid salts.  In examples (1) cloth or linen is impregnated with a solution of cetyl xanthogenate and passed through a dilute acetic acid bath, and (2) the softness or pliability of dyed artificial silk is increased by treating in a bath containing disodium phosphate and an alkyl xanthogenate obtained from the alcohols corresponding to the cocoa nut oil fatty acids; the effect can be increased by subsequent treatment in a bath containing acetic or tartaric acid.  Specification 369,978 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the addition of the alkyl xanthogenates to viscose solutions, the higher fatty alcohol being set free in the fibre by the action of the spinning bath, so that a delustred smooth artificial silk is produced.  The preparation of xanthogenates from octadecyl alcohol, cetyl alcohol, and oleic alcohol is also described.  This subject-matter does not appear in the Specification as accepted.

Patent GB-408064-A (GB)
Abstract: 408,064. Gravity-separation apparatus ; electric motor control systems. UNITED WATER SOFTENERS, Ltd., and PEMBERTON, R. T., Aldwych House, Aldwych, London. Dec. 9, 1932, No. 34991. [Class 46.] In order to remove the sludge from the bottom of the settling tank of water-softening apparatus more effectively, the sludge discharge valve is operated by a motor with automatic control means, causing the motor to open and close the valve a number of times during each sludge discharge period. The valve may be opened and closed a number of times in quick succes - sion and then left open for a longer period before it is finally closed. With the apparatus shown the valve 1, Fig. 1, of the settling-tank 2 is reciprocated by worm and screw gearing, the worm 5 being driven directly by a reversible electric motor 4, the wiring diagram for which is shown in Fig. 3.. The circuits include switches 8, 9, which are opened by a member on the valve spindle as the latter reaches its limiting closed and open positions respectively, a switch 15 closed by a slow moving disc of a clock during the sludge discharge period following each comparatively lengthy settling period, and switches 16, 31 closed alternately for short periods during the sludge-discharge period by a rapidly moving disc of the clock. At the commencement of the sludge-discharge operation, the switches 9, 15, 16 being closed a, current passes through an electromagnet 17 and closes contacts 30 to complete the motor circuit. The electromagnet at the same time moves a change-over switch 27 to ensure a closed circuit for the motor when the switch 16 is almost immediately opened by the clock. The motor circuit is closed until the valve completes its opening travel, when the switch 9 is opened. Following a period of rest, the clock closes the switch 31 and a circuit is completed through an electromagnet 32 which closes contacts 36 and thus completes the motor circuit for travel in the opposite direction to close the valve. The switch 15 may be operated manually instead of by a clock, or the clock may be started by a meter which measures the water passing through the settling tank.
