Title: Semiconductor switching devices
IPC: H01L29/744
Filed: 1962-09-27
Abstract: 983,266. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 27, 1962 [Oct. 6, 1961], No. 36658/62. Heading H1K. In a four-region, three-electrode device having first and second electrodes on one face of the wafer in contact with the first and second regions respectively and a third electrode on the opposite face of the wafer, the first PN junction is in the form of a strip with a large length to width ratio, and the second electrode has its effective perimeter close to, but uniformly spaced from, the perimeter of the first PN junction. As shown, a controlled rectifier, which can be switched on and off by means of its gate electrode, is made from an N-type silicon wafer by diffusing aluminium into its surface to form P-type layers 22, 24 surrounding an N-type layer 23. A gold-antimony N-type emitter ring 25, and gold-boron P-type gate electrodes 31, 32 and collector 21, are placed in position on the wafer and fused to the surface in a vacuum. Groove 26 is then etched through the P-type layer to divide it into two portions 22, 24. This construction provides a relatively large perimeter for the emitter junction and this enables the gate current to reduce the emitter current and hence the current gain so that the device switches off. An alternative configuration for the emitter and gate electrodes may be used to increase their co-operating perimeters, Fig. 8 (not shown). Specification 906,524 is referred to.

Patent GB-621080-A (GB)
Title: Cellulose ethers
IPC: C08B11/20
Filed: 1946-12-13
Abstract: Cellulose ethers in particulate form are subjected to extraction with an organic liquid capable of swelling the ether, but incapable of dissolving more than a small proportion thereof, and a colour-stabilizer comprising citric acid or an organic sulphite is then incorporated therein.  Preferably, the ether is an ethyl cellulose of 44-49.5 per cent ethoxy content.  The organic liquid may be methyl, ethyl, propyl or isopropyl alcohol and should contain 25-75 per cent of water, the extraction being carried out in two or more stages depending on the initial colour notability of the ehter, its particle size and density. Preferably, the temperature at which the extraction is carried out is 25-75 DEG  C., the more concentrated alcohols being used at lower temperatures.  The preferred extracting agent is 40-60 per cent ethyl alcohol.  Suitable colour stabilizers are citric acid, octyl, decyl or other higher alkyl sulphite, or a trialkyl citrate sulphite such as triethyl citrate sulphite, and they may be used alone or mixed.  The stabilizer is used in amount 0.01-5 per cent (0.05-3 per cent preferred) by weight of the ethyl cellulose. Plasticizers such as dibutyl phthalate, dibutyl stearate, tricresyl phosphate, triphenyl phosphate and n-butoxy ethyl stearate up to 50 per cent by weight of the ethyl cellulose and lubricant plasticizers up to 30 per cent may be employed.  In an example, 100 parts by weight of flake ethyl cellulose (45 per cent ethoxyl) are extracted four times with 1000 parts of 50 per cent aqueous ethyl alcohol (prepared by mixing 1 volume benzene with 200 volumes of 95 per cent alcohol and diluting with water) at 60 DEG  C.  After drying, 0.1 part of citric acid in aqueous solution is dispersed on to the ethyl cellulose which is again dried.  15 parts dibutyl phthalate are incorporated therein and the product used for moulding at 200 DEG  C.  The yellowness coefficient (as defined in the Specification) is 0.24 compared with 0.73 for the same ethyl cellulose unextracted and without citric acid.  The Specification as open to inspection under Sect. 91 describes a process for improving the colour and colour stability of cellulose ethers by extracting the ether in particulate form with an organic liquid capable of swelling the ether, but which only dissolves a small amount thereof, such liquid being an aqueous lower aliphatic mono-alcohol.  If desired, the extraction may be followed by the incorporation of a colour stabilizer such as citric acid, a derivative thereof or an organic sulphite.  Additional examples are also given.  This subject-matter does not appear in the Specification as accepted.

IPC: F16K11/065
Filed: 1964-09-14
Abstract: 1,094,565. Valves. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Sept. 13, 1965 [Sept. 14. 1964], No. 37498/64. Heading F2V. A valve unit for use in a fluid logic system consists of a laminated body of moulded plastics 10-14, which is symmetrical about the central lamina 12, the latter embodying an input which is directed to either of two outputs in laminae 11, 13 depending upon the position of a moving closure member. Laminae 10, 14 have actuating fluid inlets. The closure member is a one-piece plastics moulding made up of a pair of opposed straightsided cups 16 jointed by a pin 17. The central lamina 12 incorporates a bore (19, Fig. 2, not shown) through which a cup 16 is passed before it is moved sideways until the pin 17 reaches the end of a slot (20); the other laminae are then assembled and held in place by a clamp or an adhesive. The central lamina acts as a stop for the cups 16 and produces an air-cushion effect to reduce wear and bounce; the closure member is self-locking because the controlled fluid acts over the entire rear surface of one cup and only over that part of the other cup which is exposed through the slot. In a modification, the cups are frusto-conical, the adjacent ends of which coact with a circular opening in flexible gaskets, one on either side of the central lamina 12; the gaskets may be stretched over the closure member during assembly. Alternatively or in addition the movable closure member may be of flexible self-lubricating plastics material and the gaskets rigid and integral with the central lamina.
