Abstract: 163,306. Buchmann, S. May 12, 1920, [Convention date]. Couplings, automatic; draw-gear; couplings, operating from engine or train. -In an automatic coupling comprising two reception and two counter members on each end of the vehicle, one of the reception members locks the corresponding counter member on the opposing n.ember by means of a spring-operated catch and the other is rotatably engaged with its corresponding counter member so that it forms part of the uncoupling mechanism, the uncoupling of the vehicle being effected through gearing either from the platform or side of either vehicle. The reception members 8, 32 and the counter members 23', 5, are mounted on a bar 3 which is pivoted on the draw-bar 1. The members 8, 5 are centralized by springs in boxes 8<1>, 7 respectively and the members 23<1>, 32 have springs under the bolt heads of the flanged connections 24, 35 for flexibility. A cross-shaft 26 on each vehicle is operated either by a handwheel 27 or one from the vehicle platform connected to the spindle 22; both cross-shafts 26 are operated simultaneously when the members 23<1>, 32 are in engagement. A pinion 16 on the extension of the member 23<1> engages with a rack 14, which is connected to a lever 10 pivoted to the funnel-shaped member 8 at 9, which lever operates a spring-controlled catch 11 which is pushed outwardly on engagement with the opposing member 5 and drops back into the recess 6 to lock the coupling. On meeting, the counter members 5, 23<1> enter into the receiving members 8, 32 respectively, the member 5 being locked by the spring bolt 11. Near the end of the equalizing-bar 3 are rollers 52 which bear against the headstock when the vehicles are on a curved track. The bar 3 is connected by rods 45 and spring buffers 43 to a pivoted bracket 39, Fig. 2. The draw-bar 1 is connected to the underframing through springs 50, 51. Means are provided for adjusting the height of the coupling.

Title: Transforming an alternating electric supply to a supply having a larger number of phases
IPC: H01F30/14
Filed: 1921-05-12
Abstract: 185,801. Stigant, S. A., and Johnson & Phillips, Ltd. May 12, 1921. Phase, changing; polyphase transformers. - A three-phase system is converted into a system in which the number of phases is a multiple of three by means of a transformer with star-connected primary windings, the secondary phases being obtained in part from windings energized from two different primary phases and connected in series, and in part from windings energized from a single primary phase. The arrangement of the secondary windings for obtaining nine phases is shown diagrammatically in Fig. 2. The phases 1, 4, 7 are obtained from windings a, b, c, each of which is energized from a single primary phase, while the remaining phases 2, 3, &c. are obtained from pairs of windings a<1>, c<2>; b<1>, c', &c. energized from two different primary phases. In a modification, eighteen secondary phases are obtained, six of them from single windings and the remaining twelve from pairs of windings. Fig. 12 shows the arrangement for obtaining 24 phases. A further multiplication may be obtained by connecting adjacent terminals of the secondary windings by conducting coils provided with tappings. An example of this arrangement is shown in Fig. 13, in which the three primary phases are first converted into twelve secondary phases 1, 4, 7, - - 34 with a common junction o<1>, and the terminals of these secondary phases are connected by coils r with tappings 2, 3, 5, 6 &c., giving finally thirty-six secondary phases from the three primary phases. The coils r may be placed at any position between the common junction o<1> and the extremities of the sectors o<1>1, o<1>4 &c. to give a desired secondary voltage.

In a fuel injection device a distributer disc 11 rotated by an engine-driven shaft 12 directs fuel alternately to either end of a bore 24 containing an axially-slidable shuttle 27 which is moved by fuel pressure through a variable stroke to cause fuel at its respective opposite end to be directed to a fuel injector nozzle. A fuel pump 30, which alternatively may be a separate pump, supplies pressurized fuel to grooves 15, 16, portions (15a), Fig. 2 (not shown) of which, communicate in turn with inwardly extending portions 20a, 20b of grooves 19, 20 thereby directing fuel through passages 22, 23 to the ends of cylinder 24. The shuttle 27 forces fuel through the appropriate groove 19 or 20 to hole (18) which is aligned in turn with an appropriate outlet (21). In a modification grooves 15, 16 are replaced by a pressurized fuel gallery either between shaft 12 and disc 11 or between disc 11 and body 10. In a further modification the disc 11 is in two halves with 'O' rings arranged under compression between the halves to take up wear.

Abstract: 1,020,152. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. April 6, 1964 [April 6, 1963], No. 14005/64. Heading H1K. After providing semi-conductor elements with soldered-on electrodes and before mounting them on individual supports for use, a plurality of the elements are treated together on a common support to which they are temporarily secured by a solder of lower melting point than the solder already present in them. Each element may consist of a body of silicon, germanium or an intermetallic compound containing one or more PN junctions and the electrode solder is preferably pure lead. The solder by which they are attached to the common support is preferably a lead-gold alloy, and after treatment on the support this is melted by direct, e.g. electric current, heating or by indirect heating of the support. The adhering low melting point solder is then used to secure the separate elements to their individual mountings. The treatments carried out on the common support may include etching, testing and lacquer coating. The method is particularly applicable to the preparation of rectifier elements to be assembled into ring-type rectifiers of the form described in Specification 1,020,151.
