Abstract: 1,265,401. Control circuits for discharge lamps. ADDRESSOGRAPH-MULTIGRAPH CORP. 25 Feb., 1969 [5 March, 1968], No. 10089/69. Heading H2H.  A discharge lamp is connected in series with  an A.C. source and a controlled conduction device. A trigger circuit operates to place the device in a conductive state for a predetermined interval, and also energizes a starter electrode on the lamp. In the embodiment shown, a circuit for flashing a high-intensity radiation source such as a xenon lamp 12 provided with a trigger electrode 18 includes an A.C. input transformer. 20 and a thyristor 24 connected in series with the lamp. In the inoperative condition shown, capacitors 28 and 48 are fully charged and a further capacitor 38 is uncharged. To operate the lamp, a switch 36 is moved to position 36B so that during the next negative half-cycle current will flow into the capacitor 38 thus biasing the cathode and gate electrode of thyristor 24 into a conductive condition. A holding current through the thyristor is now provided by the discharge of capacitor 28, maintaining the thyristor conductive into the succeeding positive half-cycle. At the same time, the capacitor 48 also discharges through the primary winding 56A of a pulse transformer 56, which applies a high voltage pulse to the trigger electrode 18 enabling current from the input transformer 20 to energize the lamp for the duration of the positive half-cycle. The circuit will then return to its inoperative condition even if the switch 36 is held in position 36B. Return of the switch to position 36A discharges the capacitor 38 in readiness for subsequent operation.

Abstract: 1289046 Lubricating OLIN CORP 19 Feb 1970 [7 March 1969] 8058/70 Heading F2A [Also in Division F1] Liquid lubricant in a pumping chamber 22 is forced into a pressure system connected to a port 8 when a surge of pressure occurs in the system sufficient to move a piston 10 against the action of a spring 66. The piston 10 is hollow and contains a valve member 16 urged by a spring 84 to close an aperture 64 in communication with the chamber 22. When the piston is moved into the chamber 22 the valve member 16 lifts and allows liquid to flow around the valve into a chamber 12 and thence to the system connected to the port 8. At the end of the pressure surge the spring 66 returns the piston and a spring loaded poppet valve 18 opens to re-fill the chamber 22 from a reservoir connected to a port 4. The system may be for engine starting, Fig. 6 (not shown), in which pressurized gas from a reservoir, or produced from the combustion of a solid propellent, drives a rotary starter motor. Thus the motor receives a slug of lubricant each time the starter is operated.

Abstract: 1290142 Annealing glass H J TRESS 8 Oct 1969 [8 Oct 1968] 47630/68 Heading C1M A process of annealing a vitreous material comprises heating the material under superatmospheric pressure to a temperature above its glass transformation temperature at atmospheric pressure but below its glass transformation temperature at said superatmospheric pressure; and then reducing the pressure on the material substantially isothermally to a second pressure at or below the glass transformation pressure at the temperature of the material, and maintaining the material under these conditions until it is annealed. The transformation pressure is defined as the pressure at which there is equilibrium between the " solid " glass and liquid. After annealing the material may be cooled by again increasing the pressure to raise the transition temperature above the temperature of the material, allowing the material to cool, and releasing the pressure during cooling or after cooling is complete.

Abstract: 1290516 Fluid-pressure servomotor systems NORDISK VENTILATOR CO A S 19 Nov 1969 [22 Nov 1968 8 May 1969] 56723/69 Heading G3P [Also in Division F1] An hydraulic actuating system for angularly adjusting the impeller blades 5, Fig. 1 of a single or multi-stage fan, comprises relatively movable working cylinder 12, Figs. 1 and 6, and piston 26. In the Fig. 6 embodiment the piston 26 is fixed to the fan drive-shaft and the cylinder 12 is axially movable and is connected to blade adjusting member 7. The piston may instead be fixed to fanwheel cover 13. Alternatively the cylinder may be fixed thereto or to the fan driver shaft, the piston then being axially movable and connected to the member 7. Pressurized actuating liquid is supplied from a tank 18 by a pump through conduits 17, 33, 35 and 36 into one end of the cylinder 12, from where it passes through a restricted passage 38 in the piston 26 to a lower pressure end of the cylinder 12 and thereafter returns to the tank via conduit 39, metering opening formed by overlapping grooves 40, 41, and conduits 42, 21. In Fig.6 the cylinder is shown in its equilibrium position in which the axial forces produced by the different pressures and areas at the ends of the cylinder are balanced. Axial movement of the cylinder 12 is effected by axially moving a spool 30 within cylinder 29 by means of a rod 15, to increase or decrease the metering opening. The resulting change in the pressure differential across the piston 26 causes the cylinder 12 and attached cylinder 29 to move in the appropriate direction to a new equilibrium position. An optional passage 60 and associated groove 61 communicate the conduit 35 with the lower pressure end of the cylinder 12 when the spool 30 is moved leftwards of the equilibrium position, to thereby assist in transferring liquid from the high to the low-pressure end of the cylinder 12 and thus increase the speed at which the cylinder 12 moves leftwards to its new equilibrium position. The groove 61 may be so placed relative to groove 34 that the spool has to move a small distance from the equilibrium position before the conduit 35 is communicated via groove 61 with the lowpressure end of cylinder 12, or it may be arranged to slightly overlap the groove 34 in the equilibrium position thereby allowing increased throttling at passage 38 and consequent faster rightward movement of the cylinder 12. Leakage accumulating in chamber 70 and in groove 48 is collected via conduits 42, 49.

G16 which are activated in sequence by pulses U1 . . . U16 from a pulse distributer U to pass the data to respective registers R1 . . . R16 supplying outputs to the respective display cathode-ray tubes via channels K1 . . . K16. Each set of data includes an "end of information" signal and detection of this by a recognition . circuit E (which monitors all output data) produces an output signal which on the occurrence of the next pulse for that channel, say U1, operates via gate KS1 to change over the state of a flip-flop SFFI which blocks a coincidence circuit KA1 and thereby terminates the production of a stote read-out signa] A by OR gate OA. An address register ADR which is stepped on via the output of an OR gate OZ fed by a coincidence circuit KZ1 supplied with pulse U1 and the "1" output of a flip-flop BFFI continues to address via output AD the store positions although these are not interrogated due to the absence of the A signal. Such positions may therefore store data for other purposes distinct from the display. The display produced in this manner is rerepeated every 30 ms. by the occurrence of a "picture beginning" clock pulse ba which resets the flip-flop(s) SFFI and via gate GA causes a pre-set address in the store SP to be transferred via gate GW to the address register ADR where it forms the initial address at which the repetition commences. Each register R1 . . . R16 comprises four equal sections a, b, c and d, each of which receives one binary hexad (in parallel form) when pulse U1 is present and section a, which operates as a shift register, supplies its contents to the output channel K in serial form and then receives, in sequence, the contents of sections b, c and d in parallel which are likewise supplied to the K channel in serial form. If any channel or channels is/are not utilized for display the absence of a connected display unit causes a respective flip-flop BFFI to change its state and blocks the corresponding coincidence circuits KA1, KZ1 to prevent the production of the A and AD signals.

Abstract: 1312228 Laminates TEXTILKOMBINAT COTTBUS VEB 30 June 1971 30653/71 Heading B5N Laminar materials are made by a process in which reactive species, especially free radicals, are produced locally, e.g. in strip form on a sheet material, the treated sheet material is contacted with a shrinkage medium, e.g. a vinyl compound, hot air, hot water or saturated steam and after local shrinkage has taken place the shrunk planar body is bonded on one or both sides with another sheet material, e.g. a foil, a woven or non- woven fabric or a fleece. The reactive species may suitably be produced by radiation on a textile such as a flat warp knitted fabric. In an embodiment a polyamide flat warp silk knitted fabric 1 is locally irradiated under scan 2 of an electronic accelerator 3 with an electron beam 4. Localized strip shaped radiation is achieved by means of aluminium rods 5 which act as stencils. After irradiation the fabric is contacted with acrylic acid 6 for a sufficient period to achieve graft polymerization on the irradiated strips. Due to the shrinkage arising from the graft polymerization, the fabric is given a wavy form. After rinsing the fabric is dried in a drier 10, subsequently sprayed with an adhesive 12 on one or both sides and then a fabric is adhered to one or both sides thereof.
