Patent GB-206844-A (GB)
Title: New or improved means for the protection of dynamo-electric machines
IPC: H02H7/08
Filed: 1923-11-08
Abstract: 206,844. Siemens & Halske Akt.-Ges. Nov. 8, 1922, [Convention date]. Cut-out arrangements for motors driving roller mills in which heavy overloads, due, for example, to underheating of the material, are likely to arise and are productive of flash-overs in the motor, particularly if its speed is low, comprise cut-outs controlled by wattmeter type relays supplied with and operating in accordance with the product of, the current carried by the motor and a current proportional to the speed of the motor. As shown in the Figure, the driving motor 1 is supplied from the source 2 through the circuit-breaker 28 the trip 27 of which is actuated from the local battery 24 when the timelag relay 29, also energized from the battery 24, closes on the closure of the contacts 12, 13. These contacts are closed by the moving element of the watt-meter-type relay I, which has a current coil 5 energized from a shunt in the supply circuit and by a voltage coil 6 energized from a small generator 7 driven by the motor 1 and supplying a voltage proportional to the speed of the motor. When the product referred to reaches within say 20 per cent of the dangerous limit, the movable element of the relay I leaves the contact 10 and allows it to separate from the fixed contact 11. This opens the circuit of the electromagnet 18 and, in consequence, a signal lamp 23 is lit. If the dangerous conditions are not removed, the moving element closes the contacts 12, 13 and, after a delay imposed by the relay 29, the circuit-breaker is tripped. In order to provide for reverse running and reversal of energy in the motor a second watt-meter relay II is provided connected in parallel with the wattmeter I. The change-over switch for the motor may serve to operate a change-over switch for the current or potential coil of the wattmeter relay I and, in this case, the second wattmeter II may be dispensed with.

Title: Improvements in or relating to the surface treatment of semi-conductor elements
IPC: C23G5/00
Filed: 1959-08-18
Abstract: 861,624. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. Aug. 18, 1959 [Sept. 23, 1958], No. 28188/59. Drawings to Specification. Class 37. A process for the surface treatment of a semi-conductor element having a plurality of electrodes and at least one PN junction, comprises exposing the element to a current of vapour whilst maintaining the element at a temperature below the condensation point, so that some of the vapour condenses on its surface and continuously removing the condensate during the period of exposure to the current of vapour. The vapour may be steam-produced from highly-distilled water or may be produced from pure alcohol and if the process follows an etching process, the vapour may contain an additive suitable for neutralizing the etching residues. The condensate may be removed by the high speed of flow of the vapour, or by an additional current of compressed gas, or by subjecting the element to a rapid rotational movement The temperature of the element may be maintained below the condensation point by mounting it in good heat transfer relationship on a metal block, which may be rotated, of high thermal capacity and which may be cooled.

Title: Improvements in and relating to devices for displacing a persistent current
IPC: H01F6/00
Filed: 1963-07-19
Abstract: 992,607. Data storage. PHILIPS ELECTRONICS & ASSOCIATED INDUSTRIES Ltd. July 19, 1963 [July 24, 1962], No. 28702/63. Heading G4C. [Also in Divisions H1 and H3] A persistent current circulating about a normally conductive section of a thin layer of superconducting material below its critical temperature, is moved by shining a spot of light on it and then displacing the light spot. A data store using this principle consists of a tin layer 1000  thick on a quartz substrate with circular thin portions or apertures G 1 -G 5  each associated with a read-out wire N 1 -N 5  above or below the layer, two magnets M 1  and M 2  with their N and S poles respectively uppermost, and means, such as cathode ray tube and lens system, for moving the light spot over the layer and for extinguishing it. In operation a circulating current is generated by shining the light spot on the edge of the layer at B, moving it to one of the positions G 1 -G 5  and turning it off. Current continues to flow about the hole and is read out by shining light on it, thus causing the normally conductive section to expand thereby generating a pulse in the associated wire. Information is erased by generating a current circulating in the opposite sense by shining the light on the edge overlying the other magnet and bringing it to the hole by moving the light spot so as to cancel out the first current.

Title: Improved process of obtaining hydrogenation gas for hydrogenating coal and hydrocarbons from the waste gases of the hydrogenation
IPC: C10G1/06
Filed: 1925-11-16
Abstract: 244,730. Bergius, F. Dec. 18, 1924, [Convention date]. Hydrogen.-In the hydrogenation of coal and hydrocarbons under high pressure, the waste gases containing methane and some hydrogen are converted into gases rich in hydrogen for re-use in the hydrogenation process by subjecting them to a double treatment with steam at different temperatures. The first treatment with steam is effected at a high temperature and leads to the conversion of the methane into hydrogen and carbon monoxide, whilst the second treatment transforms the resulting carbon monoxide catalytically in known manner into hydrogen and carbon dioxide, which latter is then removed in the usual way. In the plant shown in the Figure, the gases from a hydrogenation chamber 1 first pass through a condenser 2, liquid separator 3, and devices 4, 5 for removing benzine and sulphuretted hydrogen respectively; after mixing with steam admitted by the pipe 7, the gases are conducted to a regeneratively-superheated apparatus 6 in which the first high-temperature reaction is effected; thence the gases pass, after admixture with further steam or even water from the pipe 9, to the low-temperature apparatus 8 containing such a catalyst as iron oxide; the issuing gases are then cooled in the cooler 10, compressed by the pump 11, freed from carbon dioxide in the scrubber 12, further compressed by the pump 13, and finally introduced into the hydrogenation chamber 1. The Specification, as open to inspection under Sect. 91 (3) (a) states that the process may be applied to the preparation of gases rich in hydrogen from gases containing methane and some hydrogen, such as those from coke works. This subject-matter does not appear in the Specification as accepted.
