Abstract: 872,745. Regulating-switches. GENERAL ELECTRIC CO. Ltd. June 24, 1959 [June 24, 1958], No. 20167/58. Drawings to Specification. Class 38 (5). A tap-changing switch has two sets of Geneva mechanism actuated by arms carried on a rotating shaft, one for the divertor and one for the tap changer. Each arm is carried for lost-motion relative to a sprocket on which the drive is applied. A tension spring is secured to the shaft to form an over-centre snap arrangement and the lost-motion arrangements are such that it freely carries the arms on their working arc but the driving shaft will complete the movement if the spring fails. A drum on a separate shaft is also driven by a chain and sprocket and acts as a hold-on contact for the driving motor. This drum has similar lost-motion engagements to the arms so that the motor is de-energized at the correct point in the cycle.

Title: Improvements in and relating to monogrammic apparatus for publicity purposes
IPC: G09F9/37
Filed: 1928-07-12
Abstract: 295,989. Duchard, H. M. Aug. 22, 1927, [Convention date]. Monogrammic signs.-In apparatus for displaying a continuous sequence of advertisements, the letters forming the advertisements are built up by the white faces of pivoted shutters 7 carried by continuously moving chains 2, 3, the other faces of the shutters being blue in colour so that the inoperative shutters form blue background for the other shutters. A motor 9 drives through worm gear 10, 11 one pair of the sprocket wheels on which the chains 2, 3 are mounted. The shutters are kept in position by guide 12, which is provided with a gap whereat the shutters are automatically and selectively turned to form the requisite letters. For this purpose each shutter carries two magnetic masses 13, 14 co-operating each with its own electromagnet 15a, 15b whereby the shutter may be turned to expose either its white or its blue face. The electromagnets for turning the shutters are selectively enenergized by a device comprising a known type of perforated strip which travels on an electricallyconnected rotating drum 20, Fig. 7, and controls contacts 22. Each contact 22 is connected to an electromagnet 25, Fig. 5, having an armature 26 secured to a pivoted mercury circuit-breaker 27 fitted with three terminals 29, 30, 31 connected in pairs to the electromagnets 15<a>, 15<b>, one or other of which is energized according to whether the contact 22 contacts with the drum 20 or remains in contact with the strip. Synchronous movements of the perforated strip and of the chains 2, 3 are obtained by using an electromagnetic drive for the strip. Inclined members 34 carried by the chain 2 actuate a circuit-breaker so that electromagnets 35, 36 are alternately energized, armatures 37, 38 being thereby reciprocated. These armatures are secured to a disc 38<a> having fingers 39, 40 engaging pins 41 on a disc 42, which drives the drum 20. Alternatively, a mechanical drive may be used for the drum 20. A single electromagnet may be substituted for each pair 15<a>, 15<b>. A drum may be used instead of the two chains 2, 3. When chains are used, the surface formed by the shutters 7 may be undulating instead of plane.

Title: Improvements in Electrical Phase Converting Systems.
IPC: H02K47/30
Filed: 1918-12-13
Abstract: 121,486. British Westinghouse Elec tric & Manufacturing Co., (Assignees of Fortcscue, C. Le G.). Dec. 13, 1917, [Convention date]. Systems for alternating-current motors only.-In a system where a polyphase load is supplied from a single-phase transformer, a rotary dynamo-electric phase converter is employed and its phase windings are not interconnected, but sections of them are connected between the single-phase transformer and the polyphase load. The connexions are shown for the supply of power to the motor 17 of a locomotive, the speed of which is regulated by means of an adjustable rheostat 26 in the rotor circuit. The stator windings 23 of the motor are connected to the terminals 28, 29, 30 of a switch by means of which they can be connected to the ends 3, 4, 5 of the phase windings of the converter 10. The inner ends of these windings are connected to the ends of the secondary 19 of the single-phase transformer 16 and to the middle point of the secondary as shown. The converter rotor 11 has a short-circuited winding 12, and a direct current exciting-winding 13 for synchronous operation. The connexion of the transformer winding 19 in the manner shown has the effect of reversing the phase sequence of the major components of the output electromotive forces of the phase converter. The major and minor components thus have the same phase sequence and give balanced electromotive forces which supply the motor 17. A similar action occurs during regeneration. After the motor has been disconnected, the transformer winding 20 may be connected to the terminals 3, 4 of the converter 10. This keeps the converter in operation with a minimum current. To prevent any unbalancing effect from occurring due to the degree of excitation of the rotor 11, wattless currents are allowed to circulate by the inductive coupling of the circuits of the converter and the motor in proper phase sequence by transformers 40, 45, 49. The transformer 49 may be omitted and the neutral point 43 connected to the point 0 adjacent the winding 19 or to the neutral point of the motor stator winding. Instead of using auxiliary transformers, an auxiliary delta-connected converter winding 70 with taps 71, 72, 73 may be connected to the phase converter windings as shown in Fig. 6. In another modification, a two-phase motor 83, Fig. 7, is supplied through a phase converter 75, the secondary 19 of the single-phase transformer being inserted between the inner terminals of the converter windings 77, 78. In another modification, a six-phase motor is employed.
