Patent GB-939043-A (GB)
Title: Data storage device
IPC: G11C11/22
Filed: 1961-07-10
Abstract: 939,043. Digital data storage apparatus. BURROUGHS CORPORATION. July 10, 1961 [July 20, 1960], No. 24923/61. Class 106 (1). An electrostatic digital data store comprises dielectric material 11 (Fig. 1), with conductive elements 17, 19 on it and an electrode 21 spaced from it so that when a threshold voltage between 19 and 21 is exceeded a spark discharge leaves a charge on element 17 to register a binary 1. Reading can be by one of two methods: (a) the " write " voltage pulse is repeated; the threshold is not this time exceeded due to the deposited charge on 17 and no current pulse is detected at 43 (when a binary 1 is recorded), (b) a voltage pulse in the reverse direction from the write pulse, and of lesser amplitude, is applied; the threshold is only exceeded (for a " reverse direction " spark) when the charge left by a recorded binary 1 is present to increase the effective gap voltage. Erasure is (a) by a half-strength reverse pulse; in case (b) erasure is effected by reading. Fig. 2 shows a matrix store 11 of nine elements using method (a). Selection is by a signal on one of input lines 1-9 to operate a row and a column driver which each produce a 500 volt pulse, one positive and the other negative. The threshold voltage of the storage elements is 750 volts so that a spark discharge occurs only at the selected element. The drivers are operated in the same way to read a selected element, while in a similar arrangement (Fig. 3, not shown), using method (b) a pair of drivers for each row and column is provided and a read or a write signal synchronous with the selection signal enables gates associated with the appropriate drivers. In a modification (Fig. 5, not shown), the single electrode 21 has a second electrode spaced a small distance from it, the 19-21 voltage being slightly below the spark threshold, and a spark discharge between the electrodes being initiated by pulse applied to the second electrode so that a charge can then build up at 17 after the initiating pulse is over. Specification 893,844 is referred to.

Title: Improvements in or relating to steroid compounds
IPC: C07J75/00
Filed: 1957-08-07
Abstract: The invention comprises 22b(25L)-spirost-1,4-diene-3-one and the preparation thereof by reacting a solution of neuroscogenin (1,3b -dihydroxy-22b(25L)-spirost-5-ene) in an inert solvent at an elevated temperature with a ketone or quinone in the presence of an aluminium alkoxide or phenoxide as catalyst such as aluminium t-butylate, isopropylate or phenate.  The process may be modified in that a solution of a mono-ester of neuroscogenin, in which the hydroxyl group in the 1-position is blocked with the ester group, e.g. an acyloxy group such as an acetoxy group, is reacted as above, and the product is reacted at an elevated temperature with an alcoholic solution of an alkali metal hydroxide.  The elevated temperature may be at or in the neighbourhood of the boiling temperature of the reaction mixture. The ketone or quinone may be acetone, cyclohexanone or p-benzoquinone.  Suitable reaction solvents are aromatic hydrocarbons such as benzene, toluene and xylene.  In the examples 22b(25L)-spirost-1,4-diene-3-one and the 2,4-dinitrophenylhydrazone thereof are prepared.  1 - Acyloxy - 3b  - hydroxy - 22b(25L) - spirost-5-ene is prepared by treating 1,3b -dihydroxy-22b(25L)-spirost-5-ene with the required acid anhydride or chloride to form the corresponding 1,3b -diacyloxy compound and hydrolysing this compound under controlled conditions.  In an example the 1,3b -diacetate and 1-mono-acetate of neoruscogenin (1,3b  - dihydroxy - 22b(25L) spirost-5-ene) are prepared.

Abstract: 815,699. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Aug. 12, 1957, No. 25388/57. Class 37. A semi-conductor junction device comprises a plurality of contiguous hollow cylindrical layers of different conductivity types arranged coaxially within each other. In one example the interior of a hollow cylinder of N-type germanium is closed off by means of plugs and the whole then dipped into molten indium and cooled to provide an external P-type layer. After removal of the plugs and the end sections of the cylinder by grinding or etching, a PN diode is provided as shown in Fig. 5 consisting of N-type region 1, P-type region 41 and a surrounding layer of metallic impurity 42. If the indium is allowed to reach the internal surface, during the period of suspension in the melt, a PNP device may be provided, which after removal of the end portions and part of the layers may be as shown in Fig. 9, consisting of the original N-type layer 1, P-type layers 81 and 82 and metallic impurity layers 83 and 84 to which electrodes may be attached. Further arrangements are described in which the material used initially is of intrinsic conductivity and in which, as a second stage, additional layers of selected conductivity type are produced in a similar manner to provide PNIP and like devices. In place of dipping the semiconductor body into a melt of impurity, sleeves or coatings of impurity may be provided on the body which is then heated to provide alloy-type PN junctions. The electrodes used to contact the regions of different conductivity types may consist of metallic rings or plugs. Fig. 19 shows a transistor assembly in which metallic plug 171 contacts metallic layer M adjacent a P-type layer to form the collector, ring 161C contacts outer metallic layer M, adjacent the outer P-type layer, to form the emitter, and rings 161A and 161B form dual base electrodes in contact with the central N-type base zone N.
