Title: Winding wire or other elongate flexible members
IPC: B65H67/052
Filed: 1974-12-18
Abstract: 1471876 Continuously winding wire BICC Ltd 18 Dec 1974 [21 Sept 1973] 44433/73 Heading D1J The wire being wound up on a driven reel 3, sited at a first fixed position, first passes round a driven reel 4 sited at a second fixed position, reel 4 being driven by torque motor set to supply a torque that is just sufficient to overcome windage and friction losses; a torque motor for reel 3 being set to supply sufficient torque to maintain a desired tension in the wire during wind-up. The wire is transversed by a spatulate guide 12 that is normally horizontally disposed between two upright reels 3,4. When the reel 3 is full, the spatulate 12, at the bottom of -its transverse stroke, is rocked about a horizontal axis 15 to cause the wire 9 to be snagged by gripper fingers 5 rotating with the reel 4, the wire being then cut between the reels 3,4 by a cutter on the turntable of the reel 4. The torque of the motor for reel 4 is then increased and the torque of the motor for reel 3 decreased to that necessary to overcome windage and friction only. A loop of the wire between the reel 4 and a traverse pulley 11 is then drawn out and looped around the reel 3, care being taken to cause the wire extending between the two reels to pass between the two parallel plates that - together constitute the spatulate 12. The winding of the reel 4 then continues with the reel 3 acting as a guide around which the wire passes. When the spatulate is required to rock about its axis 15, to move the wire at the bottom of a traverse stroke into the region of a snagger on either of the two turntables, this may be acheived by solenoid means.

Title: Reliability of random access memory systems
IPC: G06F12/08
Filed: 1973-01-28
Abstract: 1461245 Memory system HAWKER SIDDELEY DYNAMICS Ltd 21 Feb 1974 [28 Jan 1973] 44762/72 Heading G4A A memory system includes a memory unit interfaced with a first level bus 10, the unit comprising a plurality of sub-units interfaced with a second level bus 16 within the unit, each sub-unit comprising a plurality of blocks 14 interfaced with a third level bus 28 within the sub-unit. The memory may be formed by large scale integrated circuits, each block 14 consisting of two sub-blocks each of two 32 word read/write or read only memory chips. Each chip contains a number of access control registers including a status register, process and block registers. The status register may contain memory protection data limiting access to the chip to read or write only or data preventing the chip responding to accesses to enable the chip to function as a replacement when a different chip becomes faulty. The process and block register contents are compared with the high ordered part of a virtual address, agreement causing the remaining low ordered part of the address to be decoded to select a stored word. The control register contents may be modified, e.g. to reflect data relocation in a virtual memory or to replace a faulty chip, by the operating system software of a data processor in a so called "real access". A "real address" is supplied, over the same or different buses than a virtual address, to the appropriate block by the bus interfaces, and is compared in the selected block with a hard wired address to select the appropriate control register whose contents are modified as appropriate. The interfaces have means for isolating the various levels in the memory, i.e. a whole unit, a sub-unit, or a block, from the appropriate bus in response to faults. Two or more buses may be provided at each level to produce a multi-access port memory.

Filed: 1967-10-02
Abstract: 1,207,538. Making graphite alloys; coating graphite powder with metal. INTERNATIONAL NICKEL Ltd. Oct.2, 1967 [Oct.7, 1966; May 25, 1967], No.44789/67. Headings C7D and C7F. A process for the production of graphitic alloys comprises the steps of dispersing metal coated graphite particles in a metallic melt in which graphite is normally metallurgically incompatible, using a gaseous dispersing agent, and then cooling the melt to solidify it. The matrix metal may be Al, Mg, Zn or Cu or alloys based on these metals or on Pb or Sn. The particles may be entrained in an inert gas (e.g. Nz, Ar or He) which is preferably introduced into the bottom third or fifth of the melt, a pressure of 2-5 p.s.i. being suitable If oxidizing or chlorinating gases are used the recovery of graphite is reduced. Alternatively loose powder may be encapsulated with an agent which forms a gas at the melt temperature so that the capsule is destroyed and the particles dispersed. The graphite particles may be coated with Ni, Cu, Co, Fe, Al, Zn or alloys of these and the coating may be applied by conventional methods such as vapour deposition or chemical methods (e.g. decomposition of nickel carbonyl).

Abstract: 1412101 Recording &c. on magnetic record card DATAPLEX Ltd 2 Oct 1972 [1 Oct 1971] 45834/71 Heading G5R In an arrangement for recording data on and reproducing data from a magnetic record card, a magnetic head assembly 16 including read and write gaps 152, 154 is pivotally mounted 160 on hinge blocks 158 disposed at the free ends of a pair of flat springs 156 which are mounted on a carriage 88 movable by leadscrew 80 along guide 86 to position the head assembly over a required track on the card. Two such arrangement 10, 12 are shown, independently enclosed in a single casing 14. Referring to the lower arrangement 12, a card 30 entered via mouth 40 is pushed along guide channel 26 until the card presence is detected by both the photo-electric sensors 74, 72. This detection energizes motor 54 and pinch roller solenoids 70 so that the card is gripped and driven towards end stop 42 of the second guide channel 28. When the trailing edge of the card clears sensor 74 the motor and pinch roller solenoids are de-energized after a delay which ensures the card reaches the end stop. At this time a pair of dogs 114 which anchor the leadscrew 80 are removed from their corresponding recesses in a cam portion 110 of the leadscrew shaft so that the leadsorew is driven via a slipping clutch arrangement 92, 94, 96 to move the head assembly from a zero position to an addressed track on the tape. The required position is detected by counting complete rotations of the leadscrew (one rotation equals pitch between tracks on the card) using light source and sensor 138, 140 which co-operate with a disc 136 having a cut out sector which rotates with the shaft, and when the address count is obtained the dogs 114 again anchor the leadscrew shaft. At this time the motor is reversely driven to move the card away from stop 42 and when the leading edge of the card is detected by sensor 72 recording on or reproduction from the track occurs. When sensor 74 detects the card the direction of rotation of the motor is changed to drive the card back to the stop to await further operation. A card is ejected by switching on the motor 54 and pinch roller solenoids to drive the card towards themouth, the drive being switched off when sensor 74 detects the card and sensor 72 does not.

Title: Machine for making support material
IPC: B68G7/054
Filed: 1973-02-19
Abstract: 1427315 Coiling knots SLUMBERLAND (DEVELOPMENTS) Ltd 19 Feb 1973 45985/75 Divided out of 1427313 Heading B3E [Also in Divisions D1-D2] Specification 847,432 discloses a lattice of longitudinal twisted paper cords and transverse metal wires which pierce the inside cords and are bent around the two marginal cords by over 180 degrees but less than 360 degrees. The present Specification describes an apparatus which produces a modified lattice in that the bent over portion of the wire is subsequently bent through at least part of a turn round the main portion of the wire. At least one, preferably both of the marginal cords 33 comprises a wire core wrapped in paper or other flexible sheet material. Whilst the motion of the lattice is halted to loop one more about a marginal cord an already looped wire lies under knotting head 38, Fig. 6. The head carries a pinion 49 meshing with rack 48. As head 38 is lowered by rotation of cam 39 on shaft 41 the main portion of transverse wire 53 is enclosed by groove 50 in pinion 49 and the terminal end and the marginal cord are enclosed by slot 52 in head 38. Cam 42 moves arm 44 about pivot 45 to cause rack 48 to rotate pinion 49 through 360 degrees to knot the terminal portion of the wire about its main portion. The traverse wire is advanced by pairs of drive wheels, the upper wheel having a circumferential groove and being spring-biased into contact with the positively driven lower wheel whose circumference has axially aligned ribs or teeth. The drive shaft for the lower wheels is driven intermittently from the main cam-shaft through a geneva mechanism and changewheel gearing (Fig. 5, not shown) thus enabling the spacing of the wires to be varied. Preferably a continuous length of material comprising lattices connected by the longitudinal cords is produced by periodically omitting one or more transverse wires. Cylinder 79, Fig. 6, is operated to displace compound cam 73 along the axis of shaft 20 so that cam follower 80 contacts a cylindrical portion 74 of the cam rather than the cammed portion 75. Specification 1,427,313 describes a similar lattice in which the transverse wires are wound once or twice around the marginal cords, thereby using up the free ends of each wire.
