Sustaining pulses to the conductors of each group may be of different duration or height. Alternatively, Fig. 5 (not shown), the memory function of the panel is not used and various pulse trains are applied to the conductors of each group to produce various numbers of discharges in the 4 cells. The apparatus may be used to display a TV picture, Fig. 6 (not shown), by energizing each row of picture elements, sequentially. The video signal is periodically sampled and converted to a 4-bit digital signal for each picture element and these are stored in a shift register. When this is full its contents are applied to a buffer which provides write pulses on selected lines 1, 4, 2, 8 ... (Fig. 7) and to AND gates G xa11 , G xa12  .... Timing pulses T A , T B , T S  are sequentially applied to the AND gates G x  and also to AND gates (G y ) Fig. 8 (not shown);  pulses T s  are equal to T A  + T B . The gate outputs, either via OR gates GR or directly, control mixing currents which apply the different sustaining signals to the electrodes of the display panel. A portion of each line may be written enabling the size of the buffer to be reduced. Sustain voltage sources Figs. 10, 11 (not shown) each comprise a diode matrix and 4 transistors.

Patent GB-736479-A (GB)
Abstract: 736,479. Capacitors. WESTERN ELECTRIC CO., Inc. Oct. 23, 1953 [Oct. 25, 1952], No. 29331/53. Addition to 694,995. Class 37. In a method of producing capacitor strips comprising vaporizing a conductive film on one side of a supporting strip and applying thereto a coating of dielectric material or vice versa, as described in parent Specification 694,995, the supporting strip is mechanically stripped from the capacitor strip. Mechanical stripping is facilitated by constructions as shown in Figs. 4, 5 and 8 (not shown) wherein the supporting strip comprises a paper base with an adherent layer of a dielectric material, having a different solvent system from the dielectric layers proper, coated on the side on which the capacitor strip proper is to be formed, so that a plane of easy cleavage exists between this layer and the capacitor strip. A pair of suitable dielectrics is polystyrene, which has a benzene solvent system, and cellulose acetate which has a methyl acetate ; methylene chloride-ethylene dichloride-ethanol ; or cyclo-hexanone-acetone system. The supporting strip may alternatively be of metal foil or of a plastic having a solvent system different to the dielectric material to allow of easy stripping without the need for adjacent coated layers with different solvent systems. Suitable lacquers for use as dielectric are cellulose acetate or nitrate, high acetyl cellulose acetate, polystyrene, and cellulose acetate butyrate. A roll of capacitor strip and support strip is mounted on a supply drum 143 fitted with an internally expanding brake, and the free end carried round drum 144 which can move vertically on ball bearings 151 under control of spring 154 and which is driven at its rim by wheel 146 on which it bears. Before starting operations the end of the capacitor strip is manually separated from the support strip and wound round and cemented to the periphery of drum 144, while the free end of the support strip is carried over and cemented to the paper take-up drum 145 which is driven by a belt, the slip of which is adjustable by a tensioning idler pulley moved by lever 169. Wheel 146 is positively driven from the belt driving motor. The peripheral speeds of 146 and drum 145 are different and so arranged that the tension in the paper is at all times greater than that in the capacitor strip. Stripping speed is controlled by motor speed and by the brake on the supply drum which is adjustable by wing-nut 148. In the arrangement of Fig. 13, only the paper take-up drum is driven, the cleavage of the support strip from the capacitor strip being assisted by a knife-like jet of air directed by a shaped nozzle at the point of parting, though this is unnecessary where different dielectric layers are used.
Patent GB-765836-A (GB)
Abstract: 765,836. Piezo-electric crystals. COSMOCORD, Ltd., and STURM, R. H. Oct. 8,1952 [Oct. 17, 1951], No. 24242/51. Class 40 (8). In making a piezo-electric assembly, a surface of desired finish is produced by working on one side of the piezo-electric member, this surface is then secured to a foil or other flexible sheet and a second surface is then produced by working on the piezo-electric member. This process renders fracture of the member less likely than if the two desired surfaces were produced in one stage. When the first surface has been formed, silver particles in suspension in a synthetic resin solution are brushed on, and, after drying, a silver electrode is left on the surface. The piezo-electric plate is then coated with a moistureproof coating as described in Specification 765,835, and then stuck to a thin foil which may be of the same material as the coating. The second surface is then worked. Specification 765,834 also is referred to.

Title: Sputter-welded superconducting cable joint
IPC: H01L39/02
Filed: 1978-07-12
Abstract: End portions 31 and 32 of superconducting cable to be joined are arranged side by side, so that the end surfaces of their copper or bronze matrix 310 present a continuous surface, 34 and 35, which is etched so that the superconducting strands 311 to 314 emerge. A superconducting weld is obtained by sputtering a layer of superconducting material 40 e.g. niobium/ titanium on the continuous surface 34, 35. The surface is first cleaned by direct bombardment with an ion beam and then moved within the same vacuum chamber so that material evaporated from a target by the ion beam bombardment will be deposited on it. Further layers, which may not all be superconducting, may be deposited by utilising a rotatable multiple target support. <IMAGE>

Title: Continuously variable attack and decay delay for an electronic musical instrument
IPC: G10H1/053
Filed: 1978-09-01
Abstract: A digital instrument incorporating the effects of attack and decay by appropriately scaling the digitally synthesized waveform information at the leading and trailing portions of the waveform envelope is arranged to produce two attack and decay periods only the second of which produce an audible effect, thus resulting in a delay from the time of key actuation until the production of an audible output. The system is particularly suitable for use in an instrument in which the key signals are multiplexed as described for instance in U.S. Specifications 3515792, 3610799. A pulse generated by a key actuation causes an attack and decay counter (28) to be reset, thus beginning the attack mode and setting a flip-flop whose operation causes the scale factor to produce a zero amplitude waveform resulting in no audible sound production. At some predetermined count, a counter output decoder (32) generates a second pulse resetting the counter (28) and the gating flip-flop thereby allowing the scale factors to produce an audible attack. Upon deactuation of the key, the first set of scale factors are forced to maintain full scale factor value and the second decay period is processed unaltered through the system producing the audible decay. The first attack and decay periods provided by a variable frequency generator (22) whereby to provide continuously variable delay periods. <IMAGE>
