Filed: 1922-04-19
Abstract: 179,157. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Erickson, J.). April 29,1921, [Convention date]. Selectors. - A selector of the ratchet-driven type, designed to allow the various necessary adjustments to be readily effected, comprises an adjustable pole-piece on the armature of the driving magnet, an eccentric cam for adjusting the resting position of the armature, means for adjusting the wiper shaft relatively to the frame carrying the bank contacts so that their axes may be made coincident, and a readily-removable helical spring controlling the driving pawl. Fig. 1 shows a switch in which one or other of the wiper arms 3 makes contact with the series of bank contacts 2, and in which the permanent connection to the wipers is effected bv means of brushes connected with special terminals 29 and wiping over the arms 3. The wipers and the ratchet wheel 28 are rotatably mounted in a frame 20, which also carries the driving magnet 5. A soft-iron screw 14 of large diameter, screwing into the armature 6 and held in position by a spring washer 12 which is prevented from' turning by lugs engaging in holes in the armature, serve to adjust the length of the forward stroke of the armature. The cam-shaped member 26 adjustable by means of the screw 25 adjusts the resting position of the armature. The frame 20 carrying the wiper shaft is angularly adjustable relatively to the bank frame 21 by means of a hollow set-screw 23 which screws into the frame 20, and through which passes the holding screw 22; whilst longitudinal adjustment is effected by means of a slotted hole through which the screw 24 passes and by making the hole through the set-screw 22 sufficiently large. The spring 9 controlling the driving pawl 8 is provided with a loop which fits in a groove in the extended pivot 10 and is made wide enough to permit the easy removal of the spring. A slotted spring 36 engaging with recesses at each end of the rod 35 on which the armature 6 is pivoted prevents axial movement of the rod in its support. A pointer (not shown) on the frame 20 indicates on a dial 27 mounted on the wiper shaft, the particular set of contacts upon which the wipers are resting.

Title: Improvements in or relating to apparatus for driving elongated medium
Inventor: GOODLIFF ALAN GUIVER
IPC: G11B15/54
Filed: 1960-04-01
Abstract: 979, 171. Feeding record tapes. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 4, 1961 [April 1, 1960], No. 11499/60. Heading G5R. [Also in Division H2] In feeding a magnetic tape, a motor driving the take-up spool, and possibly the supply spool also, is started only when a capstan, disengaged from the tape, reaches full speed. Due to an associated flywheel this takes a considerable time, but then the take up spool rapidly accelerates the tape until, at the correct speed, a pinch roller brings the tape into engagement with the capstan. The capstan is driven by a three speed hysteresis synchronous split-phase capacitor-run induction motor 1, and the voltage across the capacitor 2 is used as a measure of the motor speed. This voltage is fed to a transistor circuit, which operates a relay 16 controlling the feed and/or take-up spool motors. The speed of the tape is determined in a manner described in Specification 978,045. For speed changing both the capstan and the tape are braked to rest and the capstan disengaged.

Title: Improvements in automatic telephone-exchange systems
Inventor: JOHNSON BENJAMIN BERTIE
IPC: H04Q3/00
Filed: 1949-05-02
Abstract: 686,751. Automatic exchange systems. TELEPHONE MANUFACTURING CO., Ltd. April 28, 1950 [May 2, 1949], No. 11723/49. Class 40 (iv). A system using bar and finger magnets is characterized in that each subscriber's line has means for directly energizing the associated finger magnet and for preventing energization of any other finger magnet. The apparatus employs " bar relay switches " having several banks of contacts, only one of which is operated by the armature. When subscriber No. 1 initiates a call, L pulls up to energize start relay STA in series with the ten finger magnets of the ten preselectors serving the line, these magnets being symbolized by FM and being of known type. Each finger magnet interposes its finger between the related bank of contacts, i.e. the leftmost column in Fig. 1(b), and the armature in the associated preselector. STA cuts out the start relays STB-STD for subscribers 6-20 and energises ST and STX to connect the test wires of the ten trunks 1-10 to relays SSA-SSJ. Assuming trunk 1 is free, T and SSA operate, disabling relays SSB-SSJ and energizing bar magnet BM1, which locks up and closes the previously selected bank of contacts in the first preselector. At the same time K operates to earth on wire P(a), releasing L, STA and other common relays and completing connection of the calling line to the trunk over conductors - a, +a. If the first trunk is busy, SSB or a later relay in the chain operates to employ a different preselector and its associated trunk. Subscriber 6 uses the same bank of contacts in a preselector as subscriber 1 but energizes STB instead of STA, whereupon SW also operates to connect conductors - b, +b, P(b) instead of -a, +a, P(a) to the trunk. Subscribers 11-20 use STC or STD and bar magnet BM11.
