Abstract: 1,251,442. Electro-photographic development. FUJI SHASHIN FILM K. K. Feb. 20, 1969 [Feb. 20, 1968], No.9315/69. Heading G2H. Electrostatic latent images on insulating and photo-conductive surfaces are developed with a liquid developer comprising a toner having a maximum particle diameter below 1Á in an insulating, non-polar carrier liquid containing a dissolved resin, and then before the surface dries, washing with a volatile liquid in which the resin is less soluble than in the carrier liquid so that the resin is deposited on the image-bearing surface. The washing liquid may contain toner in a concentration up to 10% of that in the developer but contains no other non-volatile ingredient. Preferably the resin is a long-oil alkyd, epoxy ester, xylene- HCHO terpene, styrene-modified alkyd, or copoly (butyl methacrylate/styrene) resin or a rosin-modified phenol-HCHO resin cooked in boiled linseed oil. The washing liquid may be an iso-paraffinic hydrocarbon or a chlorofluorinated hydrocarbon. Specified carrier liquids comprises kerosene, cyclohexane, decalin, isooctane, tetralin, vegetable oil and/or toluol. The development/washing process enables washing to be effected using high speed currents and excess washing liquid to be removed by squeeze rollers and is particularly useful for forming multi-colour images by repeated charging, exposure and development of a photo-conductive surface.

Abstract: 1,264,397. Starting systems for gas discharge apparatus. AUCO N.V. 14 Nov., 1969 [20 Nov., 1968], No. 55921/69. Heading H2H. A system for igniting a gas discharge tube is provided with means whereby after a predetermined time should the tube not have ignited, the starting operation is terminated thereby protecting the discharge tube. In a known circuit for starting a discharge lamp 1 shown in Fig. 1 the starting device 5 is replaced by a starting circuit as illustrated in Fig. 2. Upon switching on, the capacitor 12, being of smaller capacitance than that of capacitor 14, charges rapidly to provide gating pulses for a thyristor 10 which fires in the appropriate half cycles to cause heating of the electrodes 2, 3 to ignite the lamp 1. Should the lamp fail to ignite the capacitor 14 gradually charges in a stepwise manner until the diode 17 becomes non-conductive so that no gating pulses are provided for the thyristor 10 and the starting process terminates. During the starting process and whilst the capacitor 14 is charging the firing instant of the thyristor 10 occurs later and later in the halfcyles of conduction. In other embodiments the thyristor is replaced by a triac, a full-wave rectifier bridge is connected between the resistor 9 and the thyristor and lastly a full-wave bridge may be associated with the capacitors 12, 14.

Abstract: 1330247 Tool changing apparatus WERKZEUGMASCHINENKOMBINAT " 7 OKTOBER" BERLIN VEB 26 Jan 1971 3189/71 Heading B3B In machining workpieces of a series stored in individual compartments of a storage level of a multi-level central store, the storage level is step-rotated to remove successive workpieces and return them, after machining, in such a manner that the first two compartments from which workpieces are withdrawn remain empty while the level rotates unidirectionally to have succeeding compartments emptied and refilled, the two empty compartments being filled again by the final two workpieces to be machined. As shown, the production layout comprises a number of machines M1, M2, ... Mn, each with an associated conveyer arrangement F1, F2, ... Fn, and pulse counters I1, I2, ... In. The output lines from the machines and counters are connected to a distributer circuit 5 to which a central control system is connected. Connected to the circuit 5 are actual value counters Z1, Z2, ... Zm, associated comparators V1, V2, ... Vm, desired value transmitters S1, S2, ... Sm, and storage level drives A1, A2, ... Am. In operation, each storage level of the central workpiece store accommodates a series of workpieces. For performing a certain machining operation successively on the workpieces of a certain series, a particular machine, say M2, is data-linked via its conveyer arrangement and circuit 5, with the storage level, say level 3, accommodating that series. Accordingly, the storage level is rotated to place the first workpiece compartment thereof so that the first workpiece can be withdrawn by the conveyer arrangement F2. The latter initiates a count and feeds the workpiece to machine M2. Upon receipt of the count the storage level is rotated so that a second workpiece can be withdrawn. When the conveyer arrangement has removed a third workpiece, it returns the first machined workpiece to the storage level, entering it into the compartment previously occupied by the third workpiece. The level then rotates so that the second and third workpieces enter the compartments initially occupied by the first and second workpieces respectively. In each instance, the comparison of the preset desired value of workpieces in the series with the actual value count determines the ensuing event. When machining of the entire series is complete the association between that machine M2 and that series and its storage level is broken.
