Abstract: 1437108 Arc control in vacuum switches GENERAL ELECTRIC CO 16 Nov 1973 [19 Jan 1973] 53393/73 Heading H1N A high current vacuum interruptor of the kind comprising hermetically sealed envelope 11 evacuated to a pressure not exceeding 10<SP>-4</SP> torr and containing two interleaved sets of parallel rod electrodes 16, 18 forming a ring the alternate members of which are of opposite polarity, is provided with a tubular metal shield 23, at least a major portion of which surrounds the electrode ring and is electrically isolated from it, this shield further comprising metal partitions 40 projecting radially into the spaces between adjacent electrodes 16 and 18 to divide each space into two series-related arcing gaps which share the recovery voltage between adjacent electrodes. In the preferred embodiment the electrodes 16 and 18 are connected at their outer ends to the metal top and base plates 15 and 17 of the envelope 11, the insulating side-wall of which is divided into two portions 13 and 14. A flange 20 sealed between the wall portions supports the tubular shield 23 and also auxiliary shields 71, 72. The current carrying contacts comprise a fixed contact 30 rigidly connected to the top plate 15 and a movable contact 32 sealed through the bottom plate 17 via a bellows 38 located in a housing extension 39. The stroke of this contact is preferably such as to provide a gap of greater length than that of the sum of the arcing gaps between adjacent electrodes 16 and 18, and in the embodiment is approximately 2 inches. Further auxiliary shields 70 and 73 are fitted. The tubular shield 23 comprises a cylindrical body portion 19 with metal end caps 50 and 52. The shape and location of this shield is such as to obtain substantially equal capacitance between the shield and each of the electrode assemblies when the interrupter is open. The gap between contacts 30, 32 and partitions 40 is at least equal to that between electrodes and partitions. In an alternative embodiment (Fig. 3, not shown) the shield partitions are curved concentrically around the adjacent electrodes and welded at their outer edges, so that the partitions themselves form the body portion of the shield. This arrangement provides a more uniform field around the electrodes. USA Specification 3,679,474 is referred to.

Abstract: 1293585 Automatic train control BRITISH RAILWAYS BOARD 28 Oct 1970 [3 Nov 1969] 53895/69 Heading B7N In a railway signalling system a train in each track section receives from a track side loop 1, 2 &c. a first signal indicating the signal aspect at the end of that section and a second signal providing geographical information, e.g. gradients and speed restrictions, for the section in advance, this latter information being stored and made available as the train moves over a beacon 9 indicating the entry to the next section. The signals, frequency modulated on a carrier are picked up by pick-up loop 21 and demodulated in receiver 22. The geographic signal is applied, possibly via a voting circuit 39, to a buffer store in which after a check for validity using parity bits &c. in check unit 26, the signal is stored. The aspect signal is applied to logic unit 25. When the train passes the end of the section, detector 53 actuated by beacon 9 provides a signal whereby the geographic signal is transferred to a main store 28 from which it supplies the information to an arithmetic unit 32. The unit also receives from logic unit 25 signal aspect information and information on the trains position on the track derived from cross-overs in the track side loops and tachometer 37 and details of train make up, e.g. train type, length &c., and from this derives a maximum permissable speed for the train which is displayed in unit 36. The voting circuit includes a pair of delay circuits connected in series and each having a delay equal to the geographic signal repetition time period whereby three successive signals can be compared in a comparator before application to the buffer store.

Abstract: 1467969 IC engines with cylinders parallel to main shaft H H KRISTIANSEN 30 Dec 1974 [14 Jan 1974] 56025/74 Heading F1B An I.C. engine comprises a hollow cylindrical stator 10 having a chamber 11 in which a rotor 15 is mounted on a shaft supported by bearings in end caps 12, a plurality of bores being formed in the rotor with their axes parallel to the shaft axis and a piston 19 provided in each bore, a cam ring 24 at one end of the rotor, means connecting the pistons to the cam ring so that they reciprocate as the rotor turns and a cylinder head at the other end of the rotor in which a combustion chamber 44 is formed which communicates with each cylinder in turn. In the engine shown in Fig. 3, two rotors 15 are mounted on the shaft and two cams 24 are arranged back-to-back. Each cam is secured in the stator by bolts 25 which pass through slots in the stator wall to allow the cams to be rotated a small amount, relative to the cylinder head to vary the timing. The rotation is effected by toothed gearing 28, 30. The compression ratio can be changed by fitting shims 50 between the cams. The piston is connected to the cam by a link 35 fitted with pins 39 each of which carries large and small diameter rollers 38, 42 which engage opposite walls of the cam groove. The cam profile can be unsymmetrical, Fig. 6, so that the expansion and exhaust strokes are longer than the intake and compression strokes. The combustion chamber is fitted with a sparking plug or compression-ignition may be used. An air/fuel  mixture may be provided by a carburetter or fuel may be injected into the combustion chamber. Stratification of the charge is achieved by compressing the charge in the cylinder and in combustion chamber 44 in its lean state. Since chamber 44 is purged by combustion gases it contains less oxygen than the cylinder and the mixture is effectively richer. A small amount of fuel may be injected into chamber 44 and a lean mixture induced into the cylinder. In a modification, Fig. 10, the engine components are re-arranged, there being a common cylinder head 54 having a combustion chamber 56, an air or air/fuel intake and an exhaust port 56, each of which serves both sets of cylinders 59. The pistons 64 are rigidly connected to rods 62 which have a bifurcated end 71 which embraces the T-shaped periphery of a cam 68. A large diameter roller 72 runs on the outer surface 74 of the flanges 70 and two smaller rollers 75 run on the inner surfaces of the flanges. Timing and compression ratio may be varied as in the embodiment of Fig. 3.

Abstract: 1,210,586. Magnetic card apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 3 Jan., 1969 [15 Jan., 1968], No. 57758/68. Heading G4M. The apparatus is similar to that disclosed in Specification 1,210,587 but is mainly concerned with the recording and playback of a reference character at the beginning of each track. Initially the card is driven at high speed in the reverse direction (23) until photo-cell 19 is covered, track return latch 67 is set followed by D1 which resets 67 and initiates forward drive (24). If a reference character has been previously recorded on the track selected, it is gated at 75 with D1 and 19 outputs and counter 77 gives an output when all bits of the reference character have been read, to reset D1 and set D2 or D6 depending on whether record or playback mode has been selected. In the record mode the card is driven in reverse and the reference character bits are applied to time out circuit 87 which causes an output from 89 when the reference character is correctly positioned between the read and write heads, D2 being reset and D3 set. If the reference character was found to be in error or missing completely, D4 may be set to initiate recording of a reference character, the card being driven in reverse at high speed until photo-cell 19 and gate 107 reset D4 and set D5, the latter initiating forward movement of the card and gating the reference character from a register 108. Bit counter 77 indicates when all the bits have been recorded to reset D5 and set D3 via gate 115. With a correctly recorded reference character, operation to record data characters is as described in Specification 1,210,587. If the playback mode has been selected, operation is as described above for the D1 cycle and D6 is reset when a data character has been read. If a change to record mode is required before the data characters are read, D2 is set by gate 117 to reposition the reference character between the read and record heads. Similarly if a change from record to playback mode is required before the first data character is recorded, gate 119 sets D1 and resets D3, D1 being reset and D6 set when the reference character has passed the read head. If a reference character is not sensed during the playback mode, the operator can proceed to read subsequent data characters or can choose to record a reference character by changing to the record mode (gate 103 sets 67 followed by D1
