Patent GB-537980-A (GB)
Abstract: 537,980. Glycollic acid derivatives. DU PONT DE NEMOURS, & CO., E. 1. Jan. 11, 1940, No. 662. Convention date, Jan. 11, 1939. [Class 2 (iii)] Glycollic acid derivatives in which the hydrogen of the hydroxyl group is replaced by an aliphatic radical are made by subjecting a methylene glycol ether to the action of carbon monoxide, if necessary at a raised temperature and pressure, and preferably in presence of an acid catalyst. As parent materials, the dimethyl, methyl ethyl, diethyl, dipropyl, di-isopropyl, dibutyl, di-isobutyl, diamyl, dioctyl, diallyl, and dibutene ethers are specified. As catalysts, inorganic and organic acids and acid salts, and non-metal halides, e.g. boron chloride and fluoride, are specified. When boron fluoride is used, it may first be combined with the methylene glycol ether and the resulting complex reacted with carbon monoxide. Complexes of boron trifluoride with water or organic compounds, e.g. dimethyl ether, methanol, methylmethoxy acetate and glycollide, may also be used as catalysts. The methylene glycol ether and catalyst may be passed through a reaction zone in co-current or counter-current to a stream of carbon monoxide. The preparation of methylmethoxy, ethylethoxy, and isobutylisobutoxy acetates is described in examples. The products may be hydrolysed to the free acids simultaneously with or subsequently to the reaction.  The Specification as open to inspection under Sect. 91 comprises also the treatment of aryl, aralkyl, acyl, heterocyclic or alicyclic ethers of methylene glycol, and specifies the dibenzyl, diphenyl ethyl, and bis(ethoxymethyl) ethers and formaldehyde dibutene acetal. Cyclic glycol formals, decamethylene glycol formal, cyclohexyl formal, symmetrical and unsymmetrical acyl ethers of methylene glycol, e.g. the methylacetyl, diacetyl, and ethylpropionylethers, are also specified. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,208,459. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. 26 Nov., 1968 [1 Dec., 1967], No. 54779/67. Heading H2K. An arrangement for monitoring an input signal, e.g. to a motor 1, which signal is required to have a specified first or second phasing relative to a reference signal, e.g. from a supply source 2, comprises first and second circuit means responsive to input signals of the first and second phasing, respectively, to produce an output signal, and means to inhibit production of the output signal at any instant if the input signal has the phasing which is specified at that instant. In the arrangement shown, the direction of rotation of the motor 1 is determined by a servo system 3 which provides an input to the motor of a phase sequence specified by a control signal from a signal source 4. The circuit means comprise transformers 11, 16 each having a winding 12, 17 energized by the reference signal e.g. the voltage between phases R, Y, and a winding 13, 18 energized by the voltage across motor terminals 7, 8, the windings 12, 13 being additive for a specified first phasing and the windings 17, 18 being subtractive for the same phasing. Similarly, the windings 12, 13 are subtractive for the second phasing and the windings 17, 18 are additive for that phasing. The transformers also have opposing output windings 14, 19 and saturating windings 15, 20, the last windings being connected to respective thermionic valve or transistor amplifier circuits 23, 26 and 24, 27 controlled by signals from the signal source 4. In normal operation, the windings 12, 13 or 17, 18 of one transformer tend to induce an output signal in the output winding 14 or 19, but the transistor amplifier associated with that transformer is rendered conductive by the signal from the source 4 and causes the winding 15 or 17 to saturate the core of that transformer so that there is no output signal. Should the phasing of the supply to the motor be incorrect, i.e. not that specified by the signal source 4, then the transformer whose primary windings 12, 13 or 17, 18 are additive is not the transformer with the energized saturating winding 15, 20, so that an output is produced by one of the windings 14 or 19 to effect the interruption of the supply to the motor or the operation of an alarm.

Abstract: 1,187,319. Electric control system for brakes. GENERAL SIGNAL CORP. 20 Nov., 1968 [24 Nov., 1967], No. 55107/68. Heading F2F. In an over-speed controlled automatic brake system, for e.g. a locomotive, the over-speed control may be operated by wheel-slip during starting. To overcome this the OVERSPEED DETECTOR is by-passed during starting by a short-period timer. As shown an R.C. timing circuit R1C1 is charged over a " throttle off " contact 16 and a train-motion-relay contact T.M.R. (to prevent operation of the by-pass circuit by throttle closure when the train is running). The timing circuit feeds transistors T1 . . . T4 to energize a cycling relay TC until the charge on C1 leaks away. Relay TC cycles by disconnecting transistor T1 from C1 over its back contact 19. While TC cycles relay TCP is held up by the charging and discharging of capacitors C2, C3 over contacts 20, 21 of TC. With TCP up contact 26 maintains the electropneumatic brake valve EPV closed even if the overspeed relay OS opens.

[Also in Division H1] A light-emitting PN diode is made of an alloy of indium phosphide with the phosphide of gallium or aluminium the composition being such that the material has a direct band gap energy in the visible spectrum. A typical alloy, In. 5 Ga. 5 P, is grown on a seed from a solution of indium and gallium phosphides in indium in which the weight ratio of indium to gallium is 200:1. Growth is carried out either in a Czochralski puller or in a boat which is tilted to bring the seed into contact with the solution at an appropriate temperature. Deposition occurs as the solution temperature is lowered by 5‹ C. an hour. A wafer of the resulting alloy is subjected to diffusion of zinc at 1000‹ C. in an evacuated silica tube to form the PN junction, and then ultrasonically divided into discs. Each disc is alloyed N face down to a gold or tin-coated molybdenum annulus and a gold or zinc-coated molybdenum stub alloyed centrally to its P face. After mesa-etching the disc, the housing shown in Fig. 1 is completed around it. Where a laser is required the junction wafer is cleaved along 110 planes to give a precisely parallel side faces or is optically polished to achieve the same result.
