Title: Arrangement for automatically changing-over defective equipment to a spare equipment
IPC: H03F1/54
Filed: 1946-02-22
Abstract: 608,417. Two-way transmission. STANDARD TELEPHONES & CABLES, Ltd. Feb. 22, 1946, No. 5613. Convention date, May 10, 1944. [Class 40 (iv)] Means for replacing defective equipment by spare equipment is so disposed that stray capacities introduced by it are either at zero signal potential or are symmetrically disposed with respect to the conductors between the line and the equipment. This avoids cross-talk when one spare equipment is associated with two or more normal circuits. In one form of the invention, an amplifier Ar, Fig. 1, may replace either amplifier A1, A2. Under normal conditions relay contacts a1 are open and b1 are closed so that transmission takes place through windings P1, S1 and amplifier A1. If this amplifier becomes defective, contacts a1 close and b1 open so that windings P1 are short-circuited and transmission takes place over P<SP>1</SP>1 and Sr. Similar operations occur if amplifier A2 becomes defective. In a modification, Fig. 3, the third transformer is not used and when, for example, amplifier A1 is faulty, relay contacts a1 close and b1 open, so short-circuiting the amplifier and connecting winding Sl to the spare amplifier Ar. Under normal conditions in each case the capacities of the transformer windings are balanced with respect to earth, by additional condensers if necessary, and thus in effect windings P<SP>1</SP>1 and P<SP>1</SP>2 in Fig. 1 and contacts a1, b1, a2, b2 in Fig. 3 are at earth potential and no cross-talk can occur between lines L1 and L2. In the condition wherein the spare amplifier is effective, the capacities introduced between the two windings of P<SP>1</SP>1 are symmetrically disposed in relation to the corresponding windings of P<SP>1</SP>2, in Fig. 1, while in Fig. 3 the capacities of the two left-hand open contacts a2 are similarly symmetrically disposed. Under these conditions the balanced state of the system prevents any cross-talk arising from the capacity point of view. In addition, the Specification describes examples of circuits in which resistances or condensers are used in place of the transformers of the foregoing embodiments, Figs. 7, 8 (not shown). It also describes examples of the manner in which a standing potential difference may be introduced across the relay contacts in order to avoid contact noise.

Title: Improvements in method of making sliding-clasp fasteners from thermoplastic material
IPC: B29C45/14
Filed: 1937-02-26
Abstract: 489,788. Moulding sliding-clasp fasteners by injection. MORIN, L. H., and MARINSKY, D. Feb. 26, 1937, No. 5863. [Class 87 (ii)] [Also in Group XXV] In moulding sliding-clasp fastener elements 12 from thermoplastic material such as cellulose acetate, the material is forced from a heated cylinder 20 through a nozzle 22 into the cavity between relatively movable dies 33, 33a and about a vertically-movable core 36 which retains and feeds forward the cast article when the dies are moved apart. The material is fed in strip or other solid hard form as by rollers 27, 28 and forced into the cylinder 20 by a plunger 19 which also applies pressure to force the material through the nozzle into the mould. The roller 27 is driven by pawl and ratchet 29, 30 operated by an adjustable pin 32 on a lever. Portions 26b of the strip material are cut off by the plunger 19 and forced into the cylinder 20 where they are gradually rendered fluid at the nozzle 22. The cylinder and nozzle are provided with electric heating coils 23, 25 controlled by a pyrometer. The dies 33, 33a have watercooling chambers. The fasteners may be moulded on a stringer 10. When the dies are brought together, they clamp the stringer 10, engage the core 36 and leave an inlet 35. The cylinder and plunger are mounted in brackets on a slide plate 16 which is moved forward until the nozzle engages the inlet 35. After casting, the plate 16 is moved back and surplus material is removed from the article and from the nozzle by knives 40, 41, the knife 41 closing the nozzle until it is again engaged with the dies. The dies are separated, leaving the article on the core 36 which feeds it and the stringer to a position level with the lower part of the dies. thereby determining the spacing of the elements on the stringer. Groups . of elements may be spaced by independently feeding the stringer.
