Filed: 1970-11-10
Abstract: 1324400 Manipulators PROGRAMMED & REMOTE SYSTEMS CORP 10 Nov 1970 [14 Nov 1969] 53341/70 Heading B8H A master-slave manipulator comprises a master and an extendable slave arm, 25, 13 respectively and an adjustable counterweight assembly mounted on the master arm side to counteract the change in moment on extending the slave arm 13. The master arm 25 is pivotally connected at 26 to a frame 27 on which a counterweight support (36), Fig. 2 (not shown) is pivotally mounted, the slave arm counterweight 45 being movably mounted on said support. To extend the slave arm 13 without extending the master arm 25, a motor 52 operates screws 54A connected to a pulley support unit 25 which cause the unit 55 to rise thereby extending the inner segment of the slave arm 13 by movement of cables 56, 57. This increase in the slave arm length is counteracted by the raising of the counterweight 45 by means of a screw (48) which is driven by the motor 52 through a flexible shaft 50. When the motor arm 25 is moved, Fig. 4 (not shown), a link 32 causes a lever 34 to move about its pivot and a power actuator 37, by means of its extendable rod 42, will cause the support (36) to swing about its pivot, thus moving the slave arm 13 a corresponding amount by means of links 15 extending through the tube 11.

Abstract: 550,649. Bearings. STANDARD TELEPHONES & CABLES, Ltd., and HANDLEY, J. July 7, 1941, No. 8565. [Class 12 (i)] [Also in Group XXXVI] A moving coil instrument has a pivot pin arranged to bear in a conical recess in a leaf-spring and is surrounded by a member normally out of contact therewith but preventing excessive movement of the pin on shock. The instrument is housed in a casing of moulded material formed in two parts 11, 13. Supported by bolts from the rear portion 13 is a frame 15 of die-cast aluminium, which carries the mechanism. The moving coil 20 is rectangular and swings in the airgap between an inner magnet 17 and an outer ring 19. Projecting from the middle of each end of.the coil is a non-magnetic housing 25 carrying a hardened steel pivot pin 26 having a conical point. These points are received in conical recesses formed in leaf springs 27 each fixed to the frame 15 by a single screw 28 at one end only, the metal being cut away arcuately around the fixing bolt to decrease its stiffness. The free end of each spring is apertured to fit over the head of a shouldered screw so that by rotation of the screw the pressure of the spring endwise on the pivot pin can be adjusted. Surrounding each pivot housing 25 with some clearance is a clearance shock bearing 31 which seats in a V-shaped recess in the frame 15 and is held by a spring clamp 32. The pivots so protected may be more sharply pointed than usual, to reduce friction. The housings 25 are surrounded by flat spiral hairsprings 33 which have their inner ends anchored to the coil. The pointer 34 is fixed to the coil' and swings over a scale 35. Zero adjustment is effected by arms 36 fixed on the shock bearings 31 and rotatable with them with frictional resistance furnished by the clamp 32, the outer ends of the hairsprings 33 being anchored to the arms 36. Coarse adjustment is effected by the rear spring and fine adjustment by the front spring, which can be adjusted by means of an eccentric pin carried by a slot-headed rotatable member 37.

Title: Public telephone systems
IPC: H04M17/02
Filed: 1968-11-20
Abstract: 1,220,730. Coinbox substations. TAMURA ELECTRIC WORKS Ltd. 20 Nov., 1968 [6 Dec., 1967], No. 55069/68. Heading H4K. A prepayment telephone substation includes a two-winding polarized relay and an A.C. signal detector which are effective to control an encashing device irrespective of whether coin collecting signals in the form of line polarity reversal or A.C. pulses are transmitted from the exchange. Three embodiments are described in the first of which polarity reversal is used as an encashment signal on local calls whereas A.C. pulses are used on trunk calls, in the second of which A.C. pulses are used for both types of call, polarity reversals not normally being encountered, and in the third of which A.C. pulses are again used for both types of call but polarity reversals can occur on local calls, such reversals being negated by using a full-wave rectifier between the subset and line. Particular description.-On lifting of the handset hook switch contacts HS1 and HS2 close, followed by latching contact CCL when the first coin is deposited. Dial impulses are transmitted by impulsing contact Di while dial off-normal contacts Ds short-circuit the speech circuit. For a local call, the reply of the called party causes a polarity reversal whereby the potential on L1 changes from positive to negative and thereby brings up mechanically latching relay M. The latter opens the dialling circuit at m2 and connects the speech circuit to line at contact m1. The latter contact also shortcircuits relay M whereby a current surge passes "upwardly" through winding PB of a coin collecting relay P thus operating this relay and thereby encashing the deposited coin. For a trunk call or a timed local call, a pulse of A.C. is received in circuit 1 to denote called party answer or a metering period. In either case relay A comes up followed by relay M, if this is not already operative. The current surge following the closure of contact m1 passes "downwardly" through winding PA, thus operating coin collecting relay P and thereby encashing the deposited coin. With such encashment contact CC1, corresponding to a coin in the lowermost coin storage position, is opened but contact p remains closed until A relapses at the end of the A.C. pulse. Thereafter the coin in the penultimate position which initially maintains contact CC2 closed drops to the lowermost position and recloses CC1. If no more coins are deposited CC2 remains open whereby on arrival of the next A.C. pulse the operation of A causes a pay tone generator TG to inject a warning tone into the subscriber's receiver. If a further coin is still not deposited on the arrival of the next A.C. pulse the operation of A opens the loop (contacts CC1 and CC2 both open) and the connection is forcibly released. Relay M and contacts CCL are unlatched when the handset is hung-up at the end of the call. Capacitors C3, C5 serve to suppress noise caused by operation of the coin collecting circuitry.
