Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04Q1/36
Filed: 1936-01-06
Abstract: 468,632. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and LOWRY, L. P. Jan. 6, 1936, No. 453. [Class 40 (iv)] An outgoing repeater, instead of maintaining the busy guard on release to provide for the restoration of the distant switches, upon seizure imposes an arbitrary delay period before looping the junction. The delay period is such that it allows for the successive release of the selectors at two succeeding exchanges, and a connection through a considerable number of exchanges would include such a repeater in each third exchange. The repeater described is of the kind disclosed in Specification 445,099 which includes a register switch RM and a follow-up sending switch SSM. Line and release relays A, B connect up J, S, W, CB and the last relay locks. Incoming impulses are registered in an additive manner on the switch RM. dialling relay C being operative during each train. On the first operation of C, relays S, W fall back slowly in turn and connect up HA, which locks, loops the junction and disconnects CB. The latter falls back slowly and connects up IG which operates when impulse springs MS are open, inserts impulse springs LS in the forward loop and connects up impulse springs MS to step the switch SSM. Relays BB, MD energize. Corresponding terminals of wipers rm4 and ssm3 are connected to condensers, one of which is charged on the relapse of C after each incoming impulse train to mark a stopping point for the switch SSM. When the latter reaches a marked terminal, S, W pull up and disconnect IG, to conclude the outgoing impulse train, whereupon S, W relapse slowly and connect up IG again to send the next train. While IG is back, relay I energizes over the loop and holds BB. Any existing condenser charges are dissipated over wiper rm3, which is wired one step ahead of rm4. At the end of the sending operation, the switches RM, SSM are in alignment, and relays S, W remain energized and complete the talking circuit. Relay D responds on reply, and disconnects MD, whereupon DD pulls up and J falls back to effect metering. Busy flash from a succeeding stage is repeated back by I, BB and BR. Upon release by the calling party, line relay A opens the forward loop and disconnects B in the usual manner. Should release occur before J falls back, the switch RM takes one step and releases S, W, whereupon CA (which is short-circuited when the switches RM, SSM are in alignment) pulls up slowly and reguards the repeater. Relay IG closes the stepping circuit to bring the switch SSM into alignment, whereupon CA falls back. Seizure of the repeater before the restoration of the relays or of the switch SSM (i.e. before CA pulls up) does not affect such operation.

Abstract: 545,583. Permanent magnet structures. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 13, 1941, No. 476. Convention date, Jan. 12, 1940. [Class 35] Permanent magnet structures of the lifting or holding type comprise an active magnet part 32 with a permanent magnet element 30 of high coercive force, and pole-pieces 32 of high permeability and saturation between which a segment or segments 34 of the same material as the pole-pieces is fixed, with intervening non-magnetic spacers. This active part co-operates with an armature part 36 consisting of at least two spaced segments which engage the other segments in echelon so that the flux from poJe to pole and through the segmented armature crosses over from one part to the other four times (in the simple rudimentary form) and, by using more segments in each part, may be caused to cross over many times thereby greatly increasing the retaining power. The active magnet circuit is shown with a leakage gap 39, but this may be closed by a cubical permanent magnet which replaces the magnet 30. Or a U-shaped permanent magnet with attached solid pole-pieces which approach one another closely enough to provide a leakage gap and are bridged by the spaced segments co-operating, in echelon spacing, with the armature segments may be used. The permanent magnet may be prepared as described in Specification 423,897, [Group II], and the segments soldered to the poles and to the spaces by the process described in Specification 496,103, [Group II].

Abstract: 156,609. Jackson, J. L., (Assignee of Dearing, J. W.). Feb. 8, 1915, [Convention date]. Lift valves ; actuating-mechanism ; locking.-A valve device particularly applicable for use between the gas main and the meter in a building is actuated from a. remote point by a pull cable acting on a lever, and is secured in the open or closed position by a weighted lever. The actuating lever 25 is mounted on a transverse shaft 13 made in two interfitting sections and provided with bearings in the main casing and in a detachable yoke 16. Inside the casing an arm 14 on the shaft 13 engages the spindle 4 of a sliding gate valve. The yoke 16 has a split sleeve 17 adapted to be clamped by a bolt 19 about a boss on the casing with one or other of the notches on the sleeve in engagement with a projection on the casing. The actuating cable 29 is secured to one end of the lever 25 by a split ferrule 28 and bolts 30, while the other end of the lever is bifurcated and bent downwards to receive a cross-pin 27. This pin normally engages a slot 36 in a weighted lever 35, which slot is either curved about a centre below the axis of the shaft 13 or curved about that axis and formed with a depression at its upper end. When the cable is pulled the weighted lever is first slightly raised to release the pin from the slot, and then as the valve nears its seat the weight falls, causing the other end of the lever to give a hammer blow to the lever 25 and firmly seat the valve. Finally, the nose 37 on the lever 35 passes over the pin 27 to lock the valve in the closed position.
