Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1927-01-27
Abstract: 289,532. Automatic Telephone Manufacturing Co., Ltd., Passmore, W. O., and Beale, C. E. Jan. 37, 1927. Automatic exchange systems.-A two-directional finder-switch adapted to hunt freely in both directions has operating potential supplied to its self-interrupting magnets over a wiper of a distributor. The finder-switch comprises two relays only, which are energized in two different circuits at different stages in the operation. Outgoing call. When the calling subscriber takes up his receiver, his line relay 4 operates, connects earth at 5 to busy the line in the connector banks, earths the contact 14 corresponding thereto in the bank of the wiper 21 of the linefinder, and connects earth at 8 through the distributor wiper 22 to the self-interrupting vertical magnet 30 and the lower winding of relay 32. Relay 32 opens the release magnet circuit at 35, and the rotary magnet circuit at 37; the line is also switched through at 33, 34, but this is ineffectual since the finder is not on the contacts of the calling line. The line-finder wipers are stepped up until the contact 14 is reached, when changeover relay 26 energizes over its upper winding. breaks the circuits of the vertical magnet and relay 32 at 29, locks itself to the starting earth at 8 and opens another point 31 in the release magnet circuit. When relay 32 releases, the wipers are stepped by the rotary magnet 38 until the wiper 20 reaches contact 17, when relays 10, 32 energize in series, cutting the rotary magnet circuit at 37, and the line relay circuit at 12, 13, and inserting a resistance 9 in the circuit of relay 10 to mark the line engaged to other finders. The calling line is switched through at 33, 34 and earth is fed back over conductor 41 from the first selector to hold relay 26 over its lower winding, and to energize the selfinterrupting magnet 25 of the distributor so that it steps on to select an idle line-finder. The magnet windings are of high resistance to allow of self-interruption. Release. When the subscribers hang up, earth is removed from conductor 41, de-energizing relay 26 and rendering the finder selectable to the distributor. Relay 26 cuts the circuit of relays 10, 32 at 27, and the release magnet 40 operates over off-normal contacts 39. Incoming call. The connector earths conductor 3 to energize relay 10 which cuts off line relay 4 to prevent a finder starting up when the subscriber answers. Failure to find. The tenth level of the finder is permanently earthed and the wipers are rotated therein to the eleventh contact to give an alarm or to initiate release. Two sets of wipers. To deal with a group of 200 lines, each finder would require an additional set of wipers and a wiper-selecting relay, the two sets of wipers hunting simultaneously.

Abstract: 1,021,784. Fouling protection. STANDARD TELEPHONES & CABLES Ltd. Jan. 24, 1964 [Jan. 31, 1963], No. 3149/64. Heading B7N. In a fouling protection release arrangement for relay sets controlling a single track element or a group of interdependent track elements in a geographic route setting system wherein release signal transmitting and receiving links are associated with each track leading to the element or elements, means are provided when the element or elements form part of a route for applying release signals to the transmitter lines associated with the tracks from which protection was sought when the route is released and when the element or elements provided the fouling protection for adjacent elements forming part of a route for releasing the elements in response to a release signal from the adjacent elements when protection is no longer required. Assume a route from track a to d, on release of the route, a points locking relay WL and a route search relay RSC revert to their normal positions and a release signal is applied via contacts of these relays to transmitting links 4b and 4c to release the fouling protection sought, on set up of the route, from tracks b and c. Assume protection has been sought from the direction c, in this case the cross-over has been set to reverse to provide the protection and in the absence of a release signal on receive line 14c relay FR2 is released and at its contact FR21 operates a locking circuit for the fouling protection by de-energizing relay WLF. When the route requiring protection is released, a fouling protection release signal appears on line 14c which picks up relay FR2 and hence relay WLF to release the locking of the crossing.

Abstract: 652,864. Conveyers, rollerway. WILMOT. H., and SMITH, C. ST. V. Feb. 5, 1947, Nos. 3401, 3402, 3403, 3404 and 3405. [Class 78 (i)] [Also in Group II] In apparatus for metallizing the surfaces of a girder or other bar, the bar 1 is continuously rotated about its axis and moved longitudinally though cleaning, metallizing and passivating compartments 2, 3, 4 by means of conveyer units in compartments 5 at the sides of the compartments 2, 3, 4, each conveyer unit comprising spaced feed rollers 17 which rotate about their own axes and are carried by a structure 18 which rotates bodily whilst the ends of the bar are supported on trollies 21 running on rails 19 and carrying bearing plates 22 which are apertured at 23 to receive the bar. Partitions between the compartments are fitted with air blast means to prevent the contents of the compartments 2, 3, 4 passing into the compartments 5. The structure 18 is rotated by means of an electric motor 231 through a gear-box 232, shaft 233, chain 24 and sprockets 234, 25, whilst the rollers 17 are driven from the structure 18 by gearing 26, 27, 28, 29, 31, 32, 36, 37, 38, 39. Rotation of the rollers 17 may be prevented by depressing a control lever 88 to raise a projection 92 from a ratchet wheel 89. The control levers 88 of all the compartments may be operated simultaneously by means of a common shaft 95. The lower roller 17 is biassed towards the upper roller by springs 47, suitable splined connections and sliding seals being provided, and a gap between the rollers is maintained by means of an abutment head 72 engaging a stop plate 73 and set by a handoperated gear-wheel 78. In a modification (Figs. 12-15, not shown), both rollers 17 are biassed towards each other, and the means for limiting the gap between them comprises movable wedges operable from outside the compartment. Each bearing plate 22 is engaged by three rollers 146 in a triangular aperture 141 in a carrier plate 142 provided on each side with a retaining plate 144 with a circular aperture 145 slightly smaller than the bearing plate 22. The plate 142 is mounted between a pair of angle-section members 148 bridged by a plate 150 through which pass rods 151 pivoted at 152 to the plate 142 and provided with adjustable springs 154. The plate 142 may therefore move vertically and, to a limited extent, horizontally. For very heavy bars the trollies may be replaced by additional conveyer units.
