The assembly 20 comprises a holder 23 of a fluoropolymer material having a planar face 25 and a peripheral rim 25 and containing two lithium plates 30, 31 sandwiching therebetween a collector 33 of zirconium or nickel mesh. A lead 22 comprising a zirconium or nickel conductor 35 surrounded by insulation 36 penetrates the casing 10, holder 23 and lithium plate 30 and is connected to the collector 33. It is important to prevent contact between the iodine in material 50 and the collector 33 and to this end the plates 30, 31 are bonded to each other around their peripheries by the application of pressure to seal therebetween the collector; also, the peripheries of the plates are bonded by the pressure to the rim 27. To improve contact between the plates 30, 31 grooves 40 are provided. The holder 23 is secured and sealed to the casing 10 by a layer of fast-setting cyanoacrylate cement 43 and this cement may also be applied between the rim 27 and the peripheries of the plates 30,31. The cathode material 50 comprises a charge transfer complex of an organic material and iodine, the preferred organic material being 2-vinyl pyridine polymer which is an electron donor. The material 50 is a viscous flowable substance. Cathode collector 44 is of zirconium or nickel foil and is connected to a lead 46 of similar material. A plastics sheet 45 is between the collector 44 and casing 10. To ensure bonding between the insulation 36 and conductor 35 the latter is perforated (Figs. 4, 5, not shown). In another embodiment, Fig. 8, the anode comprises a pair of lithium discs 70, 72 pressure bonded together and against a current collector 74, the discs being retained in an annular holder 60 of a fluoropolymer together with two masses 80, 82 of iodine-containing cathode material. Cathode current-collectors 83, 84 contact the material 80, 82 and have leads 85, 86. The cell is sealed by a pair of plastics housing members 87, 88 surrounded by a fluoropolymer liner 89 and this assembly is enclosed in an outer hermetically sealed metal casing 90. Another embodiment. Another embodiment similar to Fig. 8 has iodine pellets providing an additional iodine supply. In another embodiment (Fig. 10, not shown) there is a single central cathode and two anodes situated to either side of the cathode. In a modification the cathode has an iodine pellet to supply additional iodine.

Filed: 1970-12-09
Abstract: 1371045 Cathode-ray tube circuits SANDERS ASSOCIATES Inc 7 Dec 1971 [9 Dec 1970] 58526/70 Heading H4T  In a cathode-ray tube display arrangement in which X and Y beam deflection signals are derived from D-to-A converters 13, 14 supplied with coded signals from respective 8-bit registers 8, 9 the five most significant bits in the output of each of the latter are supplied to respective decoder 17, 18 from which signals controlling focus, linearity and astigmatism as a function of beam position are derived. The coded signals in registers 8, 9, change in a natural binary sequence so that the inputs to decoders 17, 18 are changed on the occurrence of every eighth change in the code in registers 8, 9. Each of the latter can be set to 256 different code combination specifying 65, 536 discrete beam positions and for every 256 changes of code, 32 changes of code are applied to decoders 17, 18. The outputs from the latter appear on individual ones of 32 output lines 30, 31 and are applied to linearity connection circuits 32, 33, which supply outputs modifying the deflection (step) waveforms in amplifiers 22, 23 and to astigmatism connection circuits 34, 35 which supply outputs controlling the mean voltages between the X and Y deflection plates 20, 21. The embodiment described employs a flat screen display tube 1 of the type in which the normal (undeflected) path of the beam is parallel to the display screen, (Figs. 3 and 4, neither shown) and it is stated that, with this type of tube focus connection is necessary only in respect of deflection in the X direction. Thus, only the output of decoder 17 is supplied to the focus correction generator 42 comprising 32 weighted resistors (Fig. 2, not shown) or a chain of series connected resistors addressed consecutively. The type of tube employed exhibits trapezium distortion and this is corrected by circuit 24 which couples some of the output of the deflection amplifier 23 into converter 13 to modulate the analogue output of the latter and because the circuit is DC coupled an "off-set" potential is applied between amplifiers 22 and 23 by means of conductor 25 to change what otherwise would be a parallelogram scan into a rectangular scan. The operation of the circuit is controlled by the output of a digital computer (not shown) applied to registers 8, 9 in synchronism with a video signal applied to terminal 7 or by a clock pulse generator synchronized with the X and Y synch pulses of a video. Alternatively, the beam deflection may be controlled to trace out characters, symbols etc. or a combination of the latter and a television raster type display may be employed. Instead of a television type line raster scan a spiral scan in which the beam position is identified by its polar co-ordinates may be used.

Filed: 1968-12-16
Abstract: 1,182,240. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 16 Dec., 1968 [17 Jan., 1968], No. 59645/68. Heading G4A. In a data processing system, operand words are processed a byte at a time to obtain result bytes which are stored, the number of errorfree result bytes being counted, detection of an error inhibiting advance of the counter and causing retry of the processing starting at the next byte after that indicated by the count. Variable field length operands are read from main storage a word at a time, processed serially by byte, and written over one of the operands in main storage a word at a time (except that if the operand does not begin or end on a word boundary only part of the first or last word respectively will relate to the oper- and in reading or will modify the stored operand in writing). When result bytes are stored, a so-called VFL retry counter is incremented by the number of bytes stored. Detection of error prevents incrementing and causes retry of the current instruction without repeating derivation of all error-free result bytes, by loading an instruction address register, programme status word register and general purpose status stats from respective backup registers, adding the count to the operand "first byte " addresses derived from the instruction and decrementing the " number of bytes " field of the instruction by the value of the count, then proceeding to execute the instruction again. More than a predetermined number of such retries of an instruction causes branch to an error analysis routine.
