Abstract: 585,137. Automatic exchange equipment. STANDARD TELEPHONES & CABLES, Ltd. Feb. 9, 1945, No. 3287. Convention date, March 10, 1944. [Class 40 (iv)] A bank strip for use in a selector comprises an insulating frame 10, Fig. 1, of moulded plastic in the shape of a hollow rectangle, in the sides of which are embedded terminal pins 11. The projecting ends of these, on one or both sides, may be employed as selector, contacts. Multipling wires 18 run transversely across the pins, and are separated from them by an insulating plate 20, Fig. 2, having appropriately placed holes so that the wires may be welded to the pins. At their ends, the wires are located in grooves in the ends of the frame 10 and are held to the plate 20 by an application or insulating lacquer. Those parts or the pins 11 which are embedded in the sides of the frame may be knurled or bent to ensure positive location in the moulding. When a number of the strips is to be mounted in a rack, as for use in a selector, groups of strips are placed face to face and clamped between transverse frames 30, 31, Fig. 5, being located in a vertical plane by projections 33, Fig. 1, engaging corresponding grooves in the frames. In this case, the multipling wires are made continuous throughout a vertical run of strips, the lengths between adjacent bank strips being covered by insulating sleeving. The edges of the moulded frames may be chamfered so as to provide V-shaped grooves 53, Fig. 2, between adjacent strips when they are mounted in a rack. A connecting wire 49 between pins in the same strip can then be run in the appropriate groove and attached to the pins by collars 50 on the terminal pins.
Patent GB-643997-A (GB)
Title: Improvements in or relating to electrical measuring and indicating equipment
Inventor: GARFIELD WILLIAM LITTERY
IPC: G01R23/02
Filed: 1947-02-05
Abstract: 643,997. Frequency measuring. STANDARD TELEPHONES & CABLES, Ltd. Feb. 5, 1947, No. 3441. [Class 37] The invention introduces mains frequency monitoring equipment which in one form, Fig. 1, signals abnormal frequency and in another, Fig. 2, abnormal rate of change of frequency. In Fig. 1, oscillations on the grid of triode AMP are at a frequency which is the difference between a multiple of the mains frequency and a fixed frequency. The anode circuit of AMP includes oppositely poled rectifiers RC1, RC2 and resistances R1, R2. As the difference frequency increases with decrease of mains frequency to abnormality, the potential at the mid-point of RC1, R1 applied to grid of thyratron TH through contacts e1 of relay E attains critical value and TH strikes. Slow-acting relay D in the thyratron circuit then operates via contacts d1, e2 and potentiometer resistance PI; contacts d3 close a circuit via f3 of relay F and alarm bell AL rings. Contacts d2 on closing energize F via f1, d2, f2; e3 on closing do not energize F as it is short-circuited through e3, d2, f2. Contacts e5 operate to close circuit of " frequency low " lamp FLL. As contacts d1 open, D is open-circuited and after short time d3 opens to cut out AL; contacts d2 open, but E holds via e4, e3 and F operates. When the mains frequency has been increased to a predetermined value, anode current of AMP gives critical potential from mid-point of RC2/R2 through reversed e1 to grid of TH and the latter again strikes. D operates through d1, e2 and potentiometer resistance P2, but AL does not ring as f3 is open. Closure of d2 short-circuits E via e4, d2, f2 and E releases; F holds via f1, d2, f2 until D releases with opening of d1; the frequency normal lamp FNL lights up and the circuit is again in the condition shown. The critical frequency at which TH discharges for the second time is determined by the setting of P2 and is chosen so that FLL remains " on " until a safe condition is reached. The setting of P1 determines the " low value " at which TH first strikes. Fig. 2 includes a balanced amplifier V1-V4 which responds to PD across R; a D.C. voltage proportional to the rate of change of frequency derived as disclosed in Specifications 617,269 and 626,700 is applied at AB. Increase of rate of change in downward direction causes diode D to conduct through a1 of relay A. The P.D. then across R operates A through V1-V4 and contacts a1 change over to light a warning lamp (not shown). The condition at which the lamp is extinguished can be made different from the condition at which the lamp is lighted by potentiometer resistance P2.

Abstract: 560,621. Lighting cigarettes, cigars &c. TIBBS, D. J. March 2, 1943, No. 3455. [Class 75 (iii)] [Also in Group VI] The weight of the user's hand or wrist on a spring-supported rest 5 while holding a cigarette or cigar in contact with an S-shaped heating element 4 causes a metal ring 10 to contact with a metal ring 11 on the casing 1 and thereby completes the circuit through the primary winding of a transformer 7 supplying current to the element 4. A bimetallic strip 13 or other thermal safety switch breaks the primary circuit to the transformer if the rest is depressed too long. An ash receptacle 15 screws on to a conical funnel plate 16 secured below the hole 2 in the casing in which the element 4 is mounted, space being left for the passage of an air current. The casing 1, hand-rest 5, plate 16 and ash receptacle 15 are preferably moulded from synthetic resin and a cover plate 24 beneath the transformer of synthetic resin bonded paper board. The forward end of the casing 1 may be formed as an ash-tray 22. Instead of the heating element 4 a spark gap may be provided for lighting the cigarette or a torch element.

An armature 19, Fig. 3, carrying one contact 14b of an automatic circuit-breaker and normally attracted to a permanent magnet 17 is surrounded by a coiled conductor 16 in series with the contacts so that under overload the armature 19 is heated by the coil 16 reducing the attraction by magnet 17 and allowing the contacts to be opened by springs 11. The magnet 17 is attached to a second magnet 45 which is magnetically coupled to a further magnet 49 movable by a handle 50 so that the contacts can be manually operated between open and closed positions. The magnets 17, 45 and armature 19 are slidable on a pin 44 mounted in a sealed evacuated envelope 37. In an alternative embodiment (Fig. 2, not shown) the magnet 17 is directly attached to a push-button (6<SP>1</SP>) and is held in the closed position by a fixed magnet (34). In a third embodiment (Fig. 1) the armature 19 is maintained in the closed position by the weight of attached magnet 17 but, under overload, the magnet separates from the armature and spring 11 draws the armature upwards to separate the contacts. The armature is located in the closed position by a ball catch 8-10. Under overload, the coil 16 heats the armature to reduce the magnetic attraction, thus releasing the contacts after a time delay but under shortcircuit conditions the magnetic effect of the coil reduces the attraction instantaneously providing a current limiting action.
