Abstract: 507,117. BÒtteries; moulding. GRABEC, J., and LEDOFSKY, A. VON. May 9, 1938, No. 13825. [Class 53] [Also in Group V] The horizontal and vertical members c of a grid-like separator are of rounded or triangular section to provide line contact with the adjacent electrode. One side of the separator may be provided with ribs e and the separator may be of U- shape to enclose the electrode. The separator may be made of rubber or other mouldable substance and may be produced by passing a sheet of the substance between rollers shaped to produce a grid of the above form. The ribs e may be made by forming them separately in the form of a strip and feeding the strip between the rollers simultaneously with the separator sheet, one of the rollers having a groove corresponding to the cross-section of the strip.

Abstract: 1482084 Electrostatic spraying apparatus NATIONAL RESEARCH DEVELOPMENT CORP 18 Oct 1974 [1 Nov 1973] 50839/73 Heading B2F [Also in Division B8] Apparatus for electrostatically depositing powder, comprises a powder hopper 10 for feeding powder into the housing of a fan 12, wherein the powder is charged by triboelectrification at the surfaces of the fan rotor and the housing on rotation of the fan, and an outlet conduit 40 leading to a powder output nozzle 14. The nozzle may be metallic and connected to conduit 40 by an insulating section 42 of nylon, epoxy resin or polytetrafluoroethylene, for example. In an alternative embodiment, the nozzle is electrically insulating and contains tubes (72) Fig. 3, (not shown), skewed relative to the nozzle axis. In a further embodiment the nozzle is made from a composite material having a resistivity in the range 10<SP>7</SP> to 10<SP>9</SP> ohm-metres. The surfaces of the rotor and a lining 38 of the housing may comprise aluminium having an oxide film or they may be made of polyurethane. The hopper is shaken by a vibrator 28, the powder emerging in a fluidised state after passing through a sieve 18 across a chamber 16 around the base of the hopper before entering the fan, said chamber having a variable air intake thereto so that the density of the powder cloud emerging from the nozzle is adjustable. An alternative hopper is disclosed which maintains the powder in a dry state. The vibrator may be replaced by a powder pump comprising a helical screw in a cylindrical chamber. An alternative pump has a parallel-finned rotor, rotated about a horizontal axis, the volume of powder loaded between adjacent fins being variable according to the position of wedges which slide between the fins.

Abstract: 1449718 Drying materials RICHTER GEDEON VESYESZETI GYAR RT and MAGYAR TUDOMANYOS AKAD MUSZAKI KEM KUTATO INTEZETE 25 Nov 1974 [22 Dec 1973] 50913/74 Heading F4G The invention provides a process for continuously drying materials by milling fluidization wherein the material is in a wet solid state or is in the form of a paste or a suspension. The process comprises introducing the material into a fluidized layer of an inert charge or carrier 3 so as to distribute the particles of the material over the surface of the charge or carrier and collecting the dried or substantially dried particles of the material which are removed by the fluidizing gas or vapour from the fluidized layer. As shown the material is fed into the fluidized layer 3 by a screw 15 and the layer 3 is agitated by a stirrer 12. The layer may also or alternatively be vibrated. Drying and fluidizing gas is injected by a blower 4 after being steam heated in a heater 5. Gas is also available for injecting tangentially into the system downstream of the fluidized layer as at 7 and also into an after drying chamber 9. The gas stream then passes through a cyclone 18 and a secondary wet dust separator 19 whence it may be passed back to the blower.

Title: Gas discharge display apparatus
IPC: G09G3/10
Filed: 1973-11-05
Abstract: 1400356 Matrix displays NCR CORP 5 Nov 1973 [6 Nov 1972] 51221/73 Heading G5C A gas discharge display apparatus includes a gas discharge cell 10 which has electrodes 11 and A-G separated by electrically insulating material from an ionizable gas. A control circuit 20 is coupled to the electrodes and applies voltage pulses of uniform amplitude and alternating polarity across electrode 11 and selected electrodes A-G, whereby a wall charge is formed on the insulating material. The control circuit supplies voltage pulses of controllable duration so that the cell may be repeatedly discharged or not, according to the duration of the pulses. The electrodes A-G each form a cell with the common electrode 11 and are arranged in a seven-bar array. Electrodes A-G and 11 are insulated from the filling gas, which may be a mixture of neon, nitrogen and argon. A potential between the common electrode and a selected electrode A-G causes a discharge between the electrodes which builds up a charge (the "wall charge") on the insulation which opposes the applied potential, thus lowering the potential required to sustain a discharge, and to sustain a discharge the polarity of the potential must be repeatedly reversed. Further, the duration of the pulses may be so controlled that the discharge is maintained or not. An oscillator clock provides a train of À5 Ásec. pulses which is fed undelayed to a one-shot multivibrator 22, and with delays of T, 25T and 26T to one-shot multivibrators 26, 27, 28 respectively, where T = À5 Ásec. The outputs of the one-shot multivibrators are W, S, R, Z. A bank of OR gates 30 are connected to corresponding voltage routing circuits 60, which are connected to the corresponding electrodes A-G. OR gates 40, 41, 42 connected as shown to one-shot multivibrators 26, 22, 27, 28 are connected through voltage routing circuits 61, 62, 63 to the common electrode 11 of cell 10, and to "keep-alive" electrodes 13 in the same cell. During a "write" mode pulses W are fed through closed switches 51 to selected OR gates 30. All gates 30 receive S pulses. As the N pulses are delayed 1 Ásec. and the pulses are all À5 Ásec. long, the output of the selected OR gates is pulses 1 Ásec. long, which (unlike the À5 Ásec. pulses) are long enough to switch part of the display on, when applied to electrodes A-G via circuits 60. The wall charge formed is enough to switch the display when the pulse voltage falls to zero. Pulses R, Z are applied to OR gate 40, which produces an output RZ of 1 Ásec. pulses, interlaced with the SW pulses: these pulses are fed keep-alive electrodes 13. In a "sustain" mode, all switches 51 are open so that only the .5 Ásec. S pulses are fed to OR gates. The À5 Ásec. pulses, though not long enough to initiate a discharge, can maintain one in being. In an "erase" mode, switch 52 is opened and only À5 Ásec. S and Z pulses are available, and as they cannot sustain a discharge all discharges are extinguished.

Abstract: 1356526 Sequential switching systems R ALKAN & CIE 10 Nov 1972 [10 Nov 1971] 52029/72 Heading H2H Apparatus for supplying a number of loads C1-C4 in sequence wherein the currents flowing in the loads are controlled by thyristors TH respectively has the gate electrodes of all the thyristors, except thyristor TH1, controlled by means of AND gates ET1-ET3 respectively, each AND gate having two input signals the first of which is connected to the cathode of the preceding thyristor in the series and the second of which, in the case of the odd numbered thyristors, is connected to the output Q of a bistable trigger circuit B and, in the case of the even numbered thyristors, to the output Q of the circuit B, the switching of the circuit B being controlled by a pulse generator G.I. The gate electrode of the first thyristor TH1 is connected to the output Q of the bi-stable trigger circuit B such that after closure of a switch 4, the first control pulse at the output Q of the bi-stable circuit B causes the thyristor TH1 to conduct to supply the load C1 and to enter a signal on the first input 1 of the AND gate ET1. When the circuit B changes to produce a control pulse at the output Q a signal is entered on the second input 2 of the AND gate ET1 whereupon the AND gate produces an output 3 to fire thyristor TH2 to supply the load C2. The next control pulse at the output Q will cause the third thyristor TH3 to fire and so on. The apparatus may comprise any number of loads which may be pyrotechnic devices on aircraft and the frequency of the pulse generator determines the switching speed of the bi-stable circuit. A pushbutton 18 is provided for "single shot" operation. Resistors R are provided to ensure the sequential operation should any load C be faulty and a resistor may be placed in series with each load to limit the current flowing therein. The pulse generator GI may be a relaxation oscillator comprising a uni-junction transistor and the bistable trigger circuit may comprise a pair of transistors in a conventional form.
