Patent GB-178099-A (GB)
Abstract: 178,099. Siemens &. Halske Akt.-Ges. April 7, 1921, [Convention date]. Automatic exchange systems.-When non- numerical hunting switches are inserted between first and second group selectors, the time taken in selecting an idle second selector, for example. when both switches have to hunt to the last set of terminals, may be greater than the time interval between two sets of impulses. In order to lessen the time thus taken in seizing an idle second selector, only the first half of the terminals accessible to the first group selectors are connected over intermediate non-numerical switches, the terminals subsequently accessible being connected directly to second group selectors. The Figure shows a system in which the first group selectors IGW1 - - IGW4 are arranged in two groups A, B. The first half of the terminals in the second level of each group are connected over the trunks VLII2a, VLII2b to corresponding groups of non-numerical switches ZW1, ZW2 and ZW3, ZW, leading to second selectors IIGW23, &c., whilst the remaining terminals of both groups are connected directly to the same second selectors IIGW21, &c. The trunks connected over the switches 2W1, &c. are all marked busy as long as any of the directlyconnected trunks are available, the busy potential being removed by a relay GII energized over off-normal contacts K21, K22, &c. of the directlyconnected second selectors as soon as the latterare all engaged. In the third level of the selectors IGW1 &c., the trunk VLIII2 leading to the hunting switches ZW11 &c.. are multipled to all the selectors IGW1 &c. in both groups A and B, but the lines VLIII 1a &c. leading directly to the second selectors are separately multipled in the groups A, B respectively.

Abstract: 887,568. Semi-conductor rectifiers. GENERAL ELECTRIC CO. Ltd. June 8, 1959 [June 6, 1958], No. 18140/58. Class 37. Semi-conductor devices, e.g. power rectifiers, of the kind having electrodes formed by blocks of high thermal and electrical conductivity and cooled by cooling fluid, are mounted in communication with apertures in a support comprising a duct for cooling fluid, and removable inserts direct the cooling fluid from the duct to the base electrodes and back into the duct. As shown, one electrode of a rectifier 6 is constituted by a hollow cylindrical block of copper closed at the end bearing the semi-conductor, e.g. germanium, body, and is clamped by means of a captive nut 7 on to a tube 4 of brass or copper which is brazed or screwed to a hollow copper bus-bar 1, the bore of the tube 4 communicating with the duct 2 in the bus-bar 1 by means of an aperture in the latter. A tubular insert 9 extending from the duct 2 into tube 4 is fixed in the latter by a screw-threaded sleeve 17 bearing down on a perforated circumferential fin 14 on the insert 9. The end of the insert 9 within the duct 2 is closed, and a side opening 13 faces upstream of the flow of cooling fluid in the duct so that the fluid passes up the bore 10 of the insert 9 to cool the base electrode and back to the duct 2 via an annular passage 11 between tube 4 and insert 9. In this way, a plurality of rectifiers mounted on bus-bar 1 are cooled in series. In a modification, the hollow bus-bar 1 is replaced by a solid bus-bar brazed to a pipe ; alternatively, the bus-bar, pipe, and tube 4 are cast together as an integral unit. Reference has been directed by the Comptroller to Specification 859,849.

Abstract: 516,081. High-frequency current transformers. SIEMENS & HALSKE AKT.-GES. June 20, 1938, No. 18312. Convention date, June 19, 1937. [Class 38 (ii)] Also in Group XXXVI] Current of short wave-length is measured through a number of current transformers connected in cascade and each having a single conductor primary, the transformer ratios of the individual transformers increasing in the direction of the measuring instrument. As shown, the first transformer has ratio 1 to 5, the primary being a tubular conductor 1. The secondary 3 forms in turn a straight-through primary with secondary 4 having a ratio 1 to 20. In order to prevent the setting up of standing waves, the developed length of each secondary winding is made smaller than half an operating wavelength. The secondary 4 supplies a thermo-converter 5 and instrument 6.

Abstract: 430,610. Pneumatic relays. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. June 22, 1934, No. 18527. Convention date, July 3, 1933. [Class 8 (ii)] [See also Group XXIX] A servomotor for operating the control surfaces of aircraft and of the kind in which the operating fluid is supplied by a pump, has the byepassing relief valve associated with the pump variably loaded by a spring, the adjusting device of which is interconnected with the member operated by the servomotor so that the pressure of the operating fluid is automatically adjusted to the working requirements. In the application shown a double piston servomotor 35, 36 is linked to a rudder 39 by a link 34 and arm 38 and is controlled by a twin piston auxiliary valve connected through a floating lever 32 with the control mechanism; actuating air is withdrawn from a reservoir 43 by a pump 41 driven by a motor 42 and delivered to the auxiliary valve through a pipe 40, exhaust being returned to the reservoir through a pipe 44. The pump byepassing valve 50 comprises a lift valve member 51 loaded by a spring 56 arranged between an abutment 57 and a plunger 54 slidably mounted in the casing 55. The lower end of the plunger carries a roller 58 co-operating with a cam 58 connected by gearing 61-63 with the rudder shaft and so shaped that after the rudder has turned through a small angle the cam operates to increase the loading on the relief valve. The loading of the relief valve may be adjusted by the movements of the control instrument acting through a relay.

Abstract: 1,191,207. Load handling machines. MASSEY-FERGUSON SERVICES N.V. 19 April, 1968 [21 April, 1967], No. 18614/68. Heading B8H. [Also in Division E1] In a material-handling machine, e.g. a shovel loader, actuation of a ram 6 to move a materialhandling implement relative to a support thereof is regulated by a control system associated with a manually operable, three-way valve 46 by which fluid is supplied to and exhausted from the ram. The control system is such that, after a manually initiated movement of the valve to cause the ram to start to move the implement relative to the support, the system automatically takes over the further control of the valve to cause the valve to be held in the initiated setting until completion of the started movement of the implement and then to lock the valve in a neutral position so that no fluid can pass to or from the ram until the control system is over-ridden by further manual operation of the valve. The control system involves stop-carrying linkage 43, 44 connected together with a hand lever 5 to the valve spool 45 of the valve 46. The stop 43 co-operates with a spring-biased detent 40 operable to engage or clear the stop 43 by a slave actuator operable by pressurized fluid from a pump 24, 26 connected between the two relatively movable parts of the ram 6 as to be made operative by movement of said ram parts.
