Title: Improvements in or relating to Conveyors
Inventor: PARKER WALLACE JAMES
IPC: B65G7/00
Filed: 1968-01-19
Abstract: 1,183,023. Conveyers. HIRAM WALKER & SONS (SCOTLAND) Ltd. 8 Jan., 1969 [19 Jan., 1968], No. 2961/68. Headings B8A and B8J. Figs. 1, 2 show conveying apparatus for barrels which is laid on the floor 1 of a warehouse. The apparatus comprises end-to-end interconnected conveyer sections A, B, C, each consisting of a pair of spaced parallel boxsection tubular rails 2, 3 forming a rolling track and a pair of flat, closed, inflatable inelastic tubes 4, 5 (e.g. firefighting hoses) on the flat top faces of the respective rails 2, 3 having their closed end) ,secured thereto. A pressure-fluid supply means D provides compressed air which is connected to the tubes 4, 5 and to the rails 2, 3 respectively forming feed and exhaust trunks. Transverse feed conduit means 6 and transverse exhaust conduit means 7 interconnect the pairs of tube ends. Casing 10, 11, 16, 17 enclose valves and ducts so arranged that each pair of tubes 4, 5 is fed with compressed air at adjacent ends and connected to exhaust at the other pair of ends. A barrel deposited on the upstream end of the apparatus sealingly nips the tubes 4, 5 against the rails 2, 3 (the rails tilting inwardly to match the convexity of the barrel, Fig. 3 (not shown)). The pressure difference at opposite sides of the nip applies a rolling torque to the barrel which then travels downstream. By providing air inlet and air outlet ducting at each end of the conveyer sections the barrel may be conveyed in the reverse direction simply by operating control valve 41 to reverse the direction of circulation of the air. A series of barrels may be progressed simultaneously and there may be curved conveyer sections. In another embodiment (not shown) the runs of the tubes 4, 5 are nipped by the rollers of a load in the form of a roller carriage on which is mounted a pallet to receive material to be conveyed. In the embodiment shown in Figs. 8, 10, conveying apparatus for discrete material 53, e.g. sand or grain, includes a channel 48 of arcuate cross-section, a wide, flat inflatable inelastic tube 49, an air pump or compressor 50 and a vertically reciprocable pressure block 51 urged by a spring 54 into nipping engagement with the tube 49. A hopper 52 continuously feeds the material on to the tube 49, the block 51 co-operating with the pump 50 to produce a flow of air pulses through the tube 49. A wave motion is thus produced in the top wall 49A of the tube 49 effecting conveyance of the material along the tube in a series of hops.

IPC: H02P9/10
Filed: 1929-01-31
Abstract: 331,495. Siemens - Schuckertwerke Akt.-Ges. Dec. 21, 1928, [Convention date]. Transmission conductor arrangements; systems depending on two or more machines; regulation, automatic. - In alternating-current trunk lines with intermediate current-supplying or consuming stations and with compensation for the self-induction and capacity wattless-powers of the line, for example, by external wattless-power producers, the ohmic potential-drops of the effective currents in the line are fully or over or under compensated by supplementary wattless-currents introduced at each of the current-supplying or consuming stations in dependence on the effective current used or supplied at the station. For full compensation, the ratio of the wattless to the effective current of a section of the line or of a station is equal to the ratio of the ohmic resistance R to the inductance #L of the line or, when the two lines running in opposite directions from a station are dissimilar, the ratio of the currents of the station is equal to (<R1>/#L1 J1 - <R2>/#L2J2 ), where R<1>, R<2> are the resistances, #L<1>, #L<2> the inductances and J1, J2 the effective currents of the two lines. Generating stations have the machines underenergized to supply capacitive wattless-currents and consuming stations supply inductive wattlesscurrents. The wattless-currents may be automatically regulated by wattless-current machines or by controlling the existing potential regulators of a station or by varying condensers or choking coils or by potential-controlling transformers between the line and the bus-bars of a station. As applied to the regulator described in Specification 328,984, the Ferraris relay with an element 2 giving a torque according to the wattless-power of the station and with elements 1, 3, 4 for the compensation of the capacitive and inductive wattless-powers of the trunk line L, is provided with an additional element 5 for the compensation of the ohmic potential-drop, the relay controlling the wattless-current producer so as to keep the five torques balanced. The torques on the ele- R ments 2, 5 are EJs sin# and - EJs cos# where wL E, Js and cos# are the voltage, current and power-factor of the station. The elements 2, 5 may be combined into a single element. Specifications 23291/99 and 250,938 also are referred to.

Abstract: 1501001 Electroluminescent matrix memories; matrix displays SHARP KK 27 Jan 1975 [25 Jan 1974 13 May 1974 9 Aug 1974] 3520/75 Headings G4C and G5C A drive system is provided for an electroluminescent matrix memory panel which exhibits the hysteresis phenomenon within the light emission versus applied A.C. pulse peak voltage curve, the panel comprising a thin-film electroluminescent layer (not shown) having on one major surface thereof a set of horizontal electrodes H, Fig. 6(B), and on the other major surface thereof a set of vertical electrodes V, each cross-point of the electrodes forming a respective light-emitting unit in a matrix array. The method of operation of the panel includes the steps of appluing, prior to writing, erasing or reading of information, trains of opposite polarity maintenance pulses VHj, VVi, Figs. 7(a), 7(b), respectively, to the horizontal and vertical electrodes, the pulses being of an amplitude Vs sufficient to maintain light emission and being located in respective first and second phases #A, #B of the applied waveform. For writing information at point (HI, Vk) during the time period tw, write pulses PHW, PVW of magnitudes Vs-Vw and Vs respectively, Figs. 7(c), 7(d), are applied to electrodes Hl, Vk during the third phase #c of the applied waveform, pulse Pvw being obtained by phase-shifting the vertical maintenance pulse PVR into the third phase #c. Here the voltage Vw is sufficient to write information into the panel, the resulting write pulse Pw being as shown in Fig. 7(h). For erasing during the time period tE, erase pulses PHE, PVE of magnitudes V S -V E  and Vs respectively are applied to electrodes Hl, Vk during the third phase #c. Here V E  is small enough to cause loss of maintenance of the stored information (erase) and PVE is obtained by phase shifting the vertical maintenance pulse PVR to the third phase #c. The resulting erase pulse PE is as shown in Fig. 7(h). Read-out of information is obtained by detecting the polarization current in a light-emitting unit following the application of a read pulse P of magnitude Vs to the electrode Vk as in Fig. 7(d), the read pulse P being obtained by phase shifting the vertical maintenance pulse PVR to the fourth phase #D, and electrode Hl receiving the normal horizontal maintenance pulse PHR as in Fig. 7(c). Detection of the polarization current indicates that the light-emitting unit at (Hl, Vk) is emitting light and hence that binary 1 is stored. A circuit arrangement for driving the panel in the above manner is given in Figs. 11-15 (not shown).
