Patent GB-1316449-A (GB)
Title: Data stores
IPC: G11C11/4094
Filed: 1970-11-13
Abstract: 1316449 Data storage INTERNATIONAL BUSINESS MACHINES CORP 13 Nov 1970 [18 Dec 1969] 54019/70 Heading G4C [Also in Division H3] A stored-charge matrix data store regenerates stored data by reading, storing and regenerating it without it leaving the passive area of the store. A bit cell, e.g. 10a, is addressed by applying a pulse R in all the decode units 18, 20 to charge the nodes A, B, then applying a pulse SAR except in the units 18, 20 relating to the row column containing the required cell. When present, the pulse SAR discharges the nodes A, B. The charged nodes A, B enable (i.e. render conducting) the associated IGFETs 26, 28, 30. A bit can then be written by applying pulses # 2 , # 3  together with the complement of the bit to be written at B/L thus reading out the valve currently stored on the inter-electrode capacitance C of IGFET 12 via IGFET 16 and charging the bit-line capacitance Co with the complement of the bit to be written. A pulse 91 then writes this complement on to C via IGFET 14, after which a pulse R recharges Co via IGFET 38. This read-write sequence is then repeated but using the bit to be written (rather than its complement) at B/L, so tha tfinally the required bit is stored at C. The other bit cells in the same column (word) are regenerated during writing. Alternatively, a bit can be read from the addressed cell by applying pulses # 2 , # 3  together, # 2  enabling IGFET 16 so that if C is charged (storing 1) IGFET 12 also conducting will discharge the bit-line capacitance Co (previously charged via IGFET 38 by the R pulse) producing a pulse at the sense amplifier 42 via IGFET 40 enabled by # 3 . A column (word) can be regenerated by applying the clock pulses used in writing a bit in the column, no pulses being applied at B/L, the effect being that if C is charged indicating 1, Co will be discharged to indicate 0 via IGFETs 16, 12, this 0 being then written into C via IGFET 14, then Co is recharged by R via IGFET 38, and then since C is discharged, Co will not discharge via 16, 12 so C will be charged via 14, thus overall, Co is used to replace the 1 on C by 0 then replace this 0 by 1. If C initially had 0, it is similarly replaced by 1 which is replaced by 0. The IGFETs 32, 34 may each be replaced by a plurality of IGFETs in parallel for the decoding function. Monolithic circuitry may be used.

Title: Control system for wire-tying apparatus
IPC: F15B21/08
Filed: 1965-12-24
Abstract: 1,124,366. Twisting wires together. UNITED STATES STEEL CORP. 24 Dec., 1965 [10 Feb., 1965], No. 54811/65. Heading B3E. [Also in Divisions B8 and F1] An apparatus 2 for joining the ends of a wire W after it has been wound around a parcel P is operated by a fluid control system which controls a wire gripper 10, a wire twister pinion 8 and a pair of feed rollers 4. The wire W is fed by the rollers 4 through the twister pinion 8, past the grippers 10, around a continuous guide track 12 and through the pinion again into the gripper. The rollers 4 are then reversed to retract the wire W, strip it off the guide 12, and tension it around the package P. The twister pinion 8 is rotated anti-clockwise, to twist the wires together, by a cam-plate 18 connected through a roller and slot 16 to a sector gear 14. The control system consists of a combination of hydraulic and electric circuits (see Division F1). The hydraulic fluid from the reservoir 34 is pumped along lines 52, 58, 64 to a cylinder 28. The cylinder 28 has its piston-rod 26 connected to a pivoted jaw 24 of the gripper. The flow of hydraulic fluid causes the piston-rod 26 to retract and the jaw 24 to pivot against a fixed jaw 25 and grip the wire. The hydraulic fluid also flows to an hydraulic motor 6. When the hydraulic pressure reaches a pre-set level, a pressure opened valve 68 allows fluid to flow through it to a cylinder 22. An orifice 70 permits a slight flow of fluid to the motor 6 in order that the wire W is kept taut during the twisting operation. The cam-plate 18 continues to move until a pin 92 on it trips an arm 94 of a double-contact switch 88. The hydraulic fluid is now pumped to the cylinders 22, 28 to open the grippers 24, 25 and return the camplate 18 to its original position to close a switch 90. The closing of the switch 90 allows fluid to flow through the motor in the reverse direction and rotate the rollers 4 to feed more wire to the tying apparatus. The last part of the feed is at a slower rate.

Abstract: 1,185,468. Switching control of discharge lamps. ADMEL INTERNATIONAL Ltd. 7 Dec., 1967 [13 Dec., 1966], No. 55716/66. Heading H2H. A selector switching arrangement comprises a plurality of relays having first and second sets of contacts, and switch means for selectively connecting any one of the relay solenoids to a supply wherein the sets of contacts of the associated relay are closed. The relays are connected so that the second sets of contacts of any relay when closed shunts the solenoid of every other relay, and subsequently when the solenoid of another relay is connected to the source the shunt across its solenoid will be broken only after the first set of contacts of the previously energized relay have opened. A current limiting element is serially connected to each solenoid to avoid shunting the source. The arrangement may be used to connect an electrical device, e.g. a mercury vapour lamp 12 to a source via an element, e.g. a tapped winding 2, for supplying stepped values of electrical power. A keep-a-light circuit comprising a capacitor 20 and resistor 22 prevents extinction of the lamp on change over of contacts. The switches are mechanically interconnected so that only one is operative at any one time and in the operative position, a bridging piece connects the centre and right hand contacts. Operation of a switch 3KW energizes through ballast lamp 18 a solenoid C<SP>1</SP> closing the first contacts C/1 and second contacts C/2, C/3 the latter shunting the solenoids A<SP>1</SP>, B<SP>1</SP>. Subsequent operation of another switch 4KW passes current through a ballast lamp 16 and closed contacts C/2. Contacts C/1-C/3 open allowing the solenoid B<SP>1</SP> to be energized hence contacts B/1-B/3 close shunting the solenoids A<SP>1</SP> ,  C<SP>1</SP>. Contacts A/1-C/1 may be replaced by vacuum or mercury switches.
