Title: Improvements in electrical pulse arrangements
Inventor: BRAY FREDERICK HARRY
IPC: G11C7/02
Filed: 1961-04-07
Abstract: 985,431. Automatic exchange systems; circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. April 6, 1962 [April 7, 1961], No. 12624/61. Headings H3B and H4K. Metering pulses are stored in magnetic cores each individual to a subscriber, the individual core switching conductors LINE 000 to LINE 999 from the subscribers' private wires being connected over rectifiers to a common electronic switch ES closed for short periods only in recurring cycles so as to prevent spurious switching pulses from being registered. The switch ES has for example an open time of 105 m.s. and a closed time of 10 Ás., the closed period being just sufficient to ensure switching of a core by a metering pulse. With these switching times, a metering pulse period of about 200 m.s. and an effective length of a spurious pulse of about 30 Ás., the probability of faulty core switching is reduced to the order of approximately 1 in 4000. Rows of cores are read out in turn from a scanning access selector AS at a rate higher than the possible arrival rate of metering pulses, and outputs are obtained in column conductors CT. Specification 902,401 is referred to.

[Also in Group XL (c)] A semi-conductor device comprises a block of semi-conductor with a wedge-shaped straight edge and having a low resistance contact, and two further electrodes each consisting of a metallic ribbon having a knifeedge at one end disposed at right angles to and in contact with the block edge. In Fig. 1, two ribbon-shaped phosphor bronze electrodes 15 and 16 have knifeedges which engage the edge of cube-shaped semi-conductor block 10 which is fixed to a brass support 12 which forms a base electrode. An insulating block 25 carries the support 12 and metal supports 22 and 23 which carry the electrodes 15 and 16. The distance between electrodes 15 and 16 may be small for use as a transistor in amplifying or oscillating circuits. The electrodes 15 and 16 may be separated by a thin layer of film of insulating material to maintain the desired spacing. The arrangement enables higher contact pressures to be used to reduce noise and improves heat dissipation.

Sheet feeding, clamping, and guiding arrangements; paper-shelves.-Means for collat.ing two sheets, for example a ledger sheet and a statement sheet, comprises front and rear papershelves provided with side guides for the sheets; the front shelf may be provided with a. clamp for holding one sheet during manipulation of the other, and a finger-lever for lifting slightly one of the sheets preparatory to being manipulated by the operator. A long rear shelf 6, similar to that described in Specification 148,379, is provided with two laterally-adjustable side guides 15, 16 preferably formed on resilient plates 9 engaging a rod 8 mounted in a bead on the shelf. The side guides can be secured by means of screws 20 passing through the back of the shelf. The front shelf consists of two laterally-adjustable plates 11, 12, the plate 12 having a flange 14, and the plate 11 having a ledge 19, an extension 18, and a flange 17. A paper-finger 43, Fig. 2, rests on the extension 18. Overlapping ledger and statement sheets and carbon sheet are placed on the rear shelf, the feed-rollers 26 are released, and the sheets are passed on to front shelf, the outer sheet resting on the plate 12 and the extension 18 and being gauged by the flanges 16, 17, and the inner sheet resting on the plates 11, 12 and being gauged at one side by the flanges 14, 15, and at the other by the ledge 19. The outer or ledger sheet is then adjusted to receive the first line of writing and is clamped to the extension by means of a clamp 29, described below, after which the inner or statement sheet is adjusted, the feed-rollers are returned, and a line is typed. If the lines on the statement and ledger sheets have not the same spacing, the statement sheet is adjusted by hand before the line-spacing devices are operated, the ledger sheet being retained by hand or the clamp 29. When the statement sheet has wider line-spaces than the ledger sheet, the statement sheet is automatically fed out when the last line has been printed thereon, and a new statement sheet is then introduced, preferably by means of condensed-billing apparatus such as that described in Specification 16915/05. The clamp 29 is secured to a lever 30 on a spindle 32 provided with a finger-piece 28, a spring 31 retaining the clamp in either effective or released position. To facilitate grasping of the statement sheet, it can be raised slightly by means of a finger-lever 48, Fig. 3, pivoted on the plate 12 and formed with an arm 51 adapted on pushing the finger-piece, to pass through a slot 52 in the plate. The lever is provided with a returning-spring.

In each pair, Fig. 2, adjacent twisted sections are of opposite hand. Pairs are arranged in the cable, Fig. 1, so that the straight sections A are in line, enabling the cable to be readily terminated at any section A without having to untwist the pairs, also termination by insulation displacement connectors is facilitated. Pairs are retained in a cavity formed between two plastics sheets which may be bonded together along the length of the cable at the nip areas between pairs and at the cable edges. Bonding at the nip may be omitted in areas A to facilitate removal of pairs for termination. Insulation of pairs may be bonded to the plastics sheets. A cavity may contain more than one pair (Fig. 8, not shown). A groove (327) may be provided (Fig. 9, not shown) in the plastics sheet to facilitate stripping. In an apparatus for manufacturing the cable (Fig. 5, not shown) the plastics films are heated by suitable means (50) and pass together with the pairs between a grooved roller (34) and a resilient roller (36), the grooves defining the pair separation and the corresponding ridges urging the plastics films together for bonding. For intermittent bonding the ridges (54) of the roller (34a) (Fig. 6, not shown) are locally relieved (52) so that no contact is made between the sheets in these regions.
