Abstract: 388,742. Wire - stitching machines. DARNELL, C. H., Hemingford, Brampton Road, VERNON, K. L. and VERNON, R. C., c/o Vernon & Co., both in St. Albans, Hertfordshire. Aug. 21, 1931, No. 23527. [Class 89 (iii).] In a machine for wire-stitching sets of pages, automatic means are provided for feeding the pages to the stitching position, said means enabling a manually fed machine to be readilv converted into one in which the pages are fed mechanically. The construction involved comprises continuously moving bands engaging the pages away from the fold and leaving the latter free for the stitching operation. Feed tables are used, one for flat stitching and another for saddle stitching, and one of these may be moved out of operative position to enable the other to be used. The feed tables may extend in both directions from the stitching point so as to carry the pages to and from it. A stop is provided to hold the pages in position and is in operative connection with the stitch-forming mechanism, said stop being removed automatically when stitching occurs. A further stop is provided to hold the pages at or near the feeding-in position. Figs. 1 and 4 show a machine comprising inter alia a stitching head 11 and a table 17, with three endless bands 22 on each slope passing around terminal rollers 18 .. 21. Two of the rollers, viz. 20, 21, may have recesses for the bands, and the others may be cylindrical in form. The rollers 20, 21 are driven by bevel gears 24 .. 27 and chain-and-sprocket gearing 28, 29 from a shaft 44 which itself receives motion from the driving pulley 34 of the stitching apparatus through belt gearing 32, 31. The table 17 is mounted on a bracket 14 vertically adjusted by a hand-wheel 15 and clamped by screws 16, which on unscrewing allows of another feed table, e.g. a flat table, to be substituted. A spring-pressed clutch mechanism 35 and bevel gearing 42, 43 are interposed. A pedal 41 disengages the clutch members, and a jockey pulley 46 takes up the slack of the chain 29, and besides allowing the table to be raised or lowered in accordance with the thickness of the work, also allows the replacement of the table. A pedal 50, for operating the stitching mechanism, is automatically operated through links 51, 52 adjustable telescopically. The links are operatively connected to a follower for cams 57, 58, which thereby allow of two stitches in each revolution of the shaft 30. When the pages are first placed on the table, they contact with a stop 70, which is automatically removed from the path of the pages, by means of a cam 75 and linkage, the cam being maintained normally in position by a spring 73. In order to obtain two stitches, a stop 80 is depressed on to the table by means of a cam 86 and linkage 83, 81. At the stitching point, clamping means 90 are provided and operated by a cam 97 and linkage. Specification 350,093 is referred to.

Abstract: 896,369. Automatic - exchange systems. ERICSSON TELEPHONES Ltd. June 23, 1960 [July 8, 1959], No. 23539/59. Class 40 (4). [Also in Group XL (b)] In an arrangement for transmitting pulsecoded information, such as dial impulses, a differentiating circuit 6 (Fig. 2, not shown), produces sharp pulses of opposite signs at the beginning and end of each impulse to be transmitted; these sharp pulses, or sharp pulses of like sign produced from them by full-wave rectification, are transmitted to a receiver comprising a bi-stable circuit 7 (Fig. 3, not shown), which is thereby triggered to generate an output impulse corresponding to the original impulse, this output impulse being applied via a terminal 8 to the base of a transistor T3 which brings about the operation of a relay A in response to each such impulse. A full-wave rectifier X protects the transistor T3 in case of potential reversal. Transformers 12 are connected through terminals 9 and 10 to the speech circuit.

Title: Party line identification system
IPC: H04M15/36
Filed: 1955-08-19
Abstract: 777,099. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (International Telephone & Telegraph Corporation). Aug. 19, 1955, No. 24004/55. Class 40 (4). In an automatic exchange system, each substation on a party line is provided with an oscillator which generates a frequency identifying the substation to the exchange. The oscillator receives power from the exchange over the switch-hook contacts, and has its output connected across the dial contacts so that the identification signal is only transmitted to the exchange during dialling, and at a time when the telephone receiver is short circuited by the dial off-normal contacts. As shown, the pointcontact or junction transistor oscillates by virtue of the tuned transformer coupling 37 between collector and base when battery is applied from the line wires over the switch-hook contact 25 and dial off-normal contacts 30. The oscillator output is fed from winding 43 of the coupling transformer over the same path to line, but is short circuited by the dial contacts 29 except during the impulses themselves. At the exchange, the oscillation operates one of a plurality of tuned detectors connected across the line to bring up one of a corresponding set of relays indicating the identity of the calling subscriber.
