Title: Improvements in and relating to warp knitting machines and knitted fabrics produced thereon
IPC: D04B23/00
Filed: 1965-12-04
Abstract: 1,136,383. Knitting. J. C. DOUGHTY. 2 March, 1967 [4 Dec., 1965], No. 51526/65. Headings D1C and D1K. A warp machine is combined with one or more weft knitting units so that adjoining integral warp and weft fabrics may be knitted with interknitted junctures. The weft knitting units comprise one or more sets of needle blocks, disposed at different levels, adjoining each warp needle bed. The set(s) may be at either or both ends of the warp bed(s) and knit integral borders by taking and knitting a yarn laid-in across the warp bed and extended across the weft unit, or by knitting a separate yarn, and making a juncture by interknitting warp fabric yarns. Alternatively the set(s) may be co-extensive with the warp beds so that by feeding a separate yarn to the unit and inter-relating the operation of the warp and weft needles the fabrics may be interknitted, or a weft appendage, joined to the warp at one or both edges only; knitted. The unit may be arranged to knit a weft fabric between and integral with warp portions. The machine may be circular. In the particular embodiment described each of two needle beds comprises a series of curved hollow tubes through which the warp thread pass. The beds oscillate in a direction from back to front of the machine, and may be shogged relative to one another. Fabric is knitted by wrapping the yarn emerging from the 'needles' of one bed about the needles of the other.
Patent GB-516535-A (GB)
Abstract: 516,535. Calculating-apparatus. WEBB, C. F. June 25, 1938, No. 18903. [Class 106 (i)] In a machine of the key-controlled multiplebank type, a transfer from one totalizer wheel to the adjacent wheel of higher order is effected through the intermediary of a pin or pins engagable in a slotted wheel, the arrangement being such that the slotted wheel is brought to rest by a pin immediately before the latter disengages the slotted wheel whereby the wheel of higher order is brought to rest in its correct position at the end of the transfer operation. The transfer mechanism for each denomination comprises four twenty-toothed wheels 15, 27,. 29, 34, Figs. 2 and 3, rotatably-mounted in pairs on shafts 14, 26. A ten-toothed pinion 12, Fig. 2, fixed to a numeral wheel 10 by an arm 50 is rotated clockwise by the rack 13. The wheel 15 gears with the pinion 12 and with the wheel 27 which ds connected by a spiral spring 28 to the wheel 29, Fig. 3, in gear with wheel 34. A cam 16 fixed to the wheel 15 is engaged by arms 21, 23 of two bell-crank levers. the other arms 22, 24 of which co-operate with a stop-plate 35 fixed to the wheel 34. As the pinion 12 completes its first revolution the arm 23 of one bell-crank falls into a recess 18 in the cam whereupon the arm 24 releases stop-plate 35 and allows a halfrevolution of wheel 34 by the tensioned spiral spring. During this movement one of two pins 37, Fig. 4, on the opposite face of the wheel 34 engages and steps forward a slotted wheel 38 associated with the numeral wheel of the next higher denomination, the latter being positively brought to rest before the pin leaves the slot. To prevent a transfer to a numeral wheel while the latter is being independently rotated, a spring-pressed lever 45, Fig. 5, engaged at its upper end 47 by the driving bar 48, moves into the path of pins 37 when the latter descends thereby preventing any movement of wheel 34 until the bar 48 is returned. To render any transfer inoperative in the case of subtraction, a button 53 associated with each numeral wheel is arranged to move a slide 56 having a cam surface 57 which, forced between plate 58 and the slotted wheel 38, moves the latter laterally against a spring out of range of the pins 37. Zeroizing. The pinions 12 are normally prevented from anti-clockwise rotation by the spiral springs 28 by means of detents 39, Figs. 2 and 4. In order to zeroize, a common yoke 42 operated by an exterior handle is rocked to release all the detents, the parts returning to zero position where they are held by the engagement of either arm 21 or arm 23 with the stop 18 on the cam. Specifications 514,289, 514,290 and 516,557 are referred to.

Abstract: 1,176,780. Stand-by supply systems. STANDARD TELEPHONES & CABLES Ltd. 7 Nov., 1968, No. 52774/68. Heading H2H. Supply system includes a control circuit which causes a main supply to charge a battery under normal conditions, and connects the battery to an inverter to replace the main supply on failure of the latter. The supply is regulated by a constant voltage transformer. In the circuit shown in Fig. 1, a load 7 is normally fed by mains supply 6 which is connected to the saturated resonant tank circuit of transformer T1. If the mains should fail, the transformer is energized from a battery 1 through a parallel inverter 2. In normal operation, the mains voltage is sufficient to close contacts RLA-1 and RLA-2 so as to supply current to the transformer and also provide a signal to the control circuit 8. The control also receives a signal from the battery, and the charging current fed to the battery using the inverter 2 is adjusted according to the existing state of charge by altering the phase difference of the mains and inverter output. The control circuit 8, Fig. 2 (not shown), includes a unijunction transistor oscillator which determines the output frequency, a bi-stable pulse circuit for providing thyristor gating pulses, a synchronizing circuit, a phaseshifting circuit, and a reference circuit. Modifications, Figs. 3-5 (not shown), include the replacement of switch RLA-1 by a thyristor device, and an alternative control circuit which includes a thermistor for indirectly sensing the battery voltage.

Title: Data stores
IPC: G06F5/06
Filed: 1971-11-15
Abstract: 1362034 Data store SIEMENS AG 15 Nov 1971 [22 Jan 1971] 52917/71 Heading G4C A data store comprises a matrix array of cells in rows and columns, each row of cells being a shift register, the store being arranged such that data is written into individual storage cells in accordance with conventional X-Y co-ordinate addressing techniques and data is read from the store only by serial read out from consecutive shift registers. As described the store I comprises an array of storage cells, the rows 2-6 being shift registers. One of the shift registers forms an auxiliary register which replaces a register being read out. Matrix addressing is achieved with the aid of conventional X and Y address decoders 7 and 9. The registers 2-6 are read out in sequence by shift pulses supplied to terminal 13, the appropriate register being connected to output 11 by multiplexer 10 under the control of device 12. When a register, say register 2, has been read out register 3 is connected to the output and read out begins. During the read out of register 2 the row (X) address decoder 8 outputs are, by means of switching device 9 which is controlled by device 12, modified such that the, now empty, register 2 replaces register 3 thus enabling new data intended for register 3 to be read into the store during the read out of register 3. When read out from register 3 is complete read out from register 4 begins and register 3 replaces register 4. During the read out from the first register 2, register 6 serves as the replacement register. Thus when register 5 has been read out a storage cycle is complete. Read out may continue by a serial read out from register 6 which has replaced register 2 (see above). Alternatively read out may recommence with the last storage location previously read out and continue in reverse. In this latter case however the last storage location read out would normally be located in the left most cell of the register which served as the replacement during the final register read out in the previous cycle, i.e. register 4. To overcome this each time a register which has just been read out is assigned as a replacement for a register which is about to be read out the column address inputs from decoder 7 to that register are reversed. Read out then recommences with register 4 in the normal way. In a modification only four registers are provided. To enable data to be written into a register being read out the column address decoder outputs are modified to take account of the position shifting during read out. It is stated that each storage cell may be formed by MOS elements.
