Title: Improvements in or relating to automatic telephone switching systems
IPC: H04Q3/00
Filed: 1961-08-18
Abstract: 990,547. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Aug. 18, 1961 [Aug. 30, 1960], No. 29881/61. Heading H4K. In a cross-bar exchange each calling substation has a plurality of keys, one for each station to be called, and depression of a key causes the cross-bar switch to connect the calling station to the station associated with that key. In the embodiment described, a 10 x 10 cross-bar switch arranged for double group working effects connections between ten key set stations and sixteen called lines (of which ten may be those of the key set stations) It is assumed that the user of key set 1 (Fig. 2), wishes to call line 2 (Fig. 3). He removes his handset and depresses key 22, thus grounding lead PI1 to bring up relay PI1, indicative of the calling station, followed by relay PIG. Ground is thus applied to LIG1 and extended via key 22 and lead LI2 to operate the select magnets SM1 and SM2, appropriate to the called line, during the operate time of SMT, whereafter hold magnet HMO, appropriate to the calling station, pulls up to extend the caller to line 2. The slow-to-operate relay RLS releases PI1, SM1, SM2 and SMT, but holds PIG. Relay PIG ensures that if several callers initiate calls simultaneously, they are all served before any later would-be caller. Extra lines, such as 17, not connected to the cross-bar switch, may be reached directly by depression of keys such as 25. Conventional holding circuits (Fig. 3) are provided operable by hold key 26 (Fig. 2) at the calling station to permit interim conversation between the caller and a third party.

Filed: 1926-11-29
Abstract: 263,770. Compagnie, pour la Fabrication des Compteurs et MatÚriel d'Usines Ó Gaz. Dec. 23, 1925, [Convention date]. Protective arrangements.-Alternating current, pressure, or power relays are operated by a system having a number of phases different from that of the main circuit, in order to simplify the construction of the apparatus. The transformation may be effected either internally or externally of the apparatus. Fig. 1 shows an induction type ammeter or relay employed in a three-phase circuit, the current being transformed to twophase within the instrument. The disc D is acted on by an electromagnet having a coil a connected in the main 1 and also by an electromagnet having reversely wound coils b, b<1> connected in the mains 2, 3. The number of turns of the coil a is #3 times the number of turns on each of the coils b, b'. In a modification the two coils b, b<1> are replaced by a single coil in series with the secondary winding of a transformer having two reversely wound primary windings connected in the mains 2, 3, the phase transformation in this case being effected outside the instrument. In the modification shown in Fig. 3, two current transformers T, T' are so connected that their secondary currents traverse the coil a in the same direction and the coils b, b<1> in opposite directions. Three current transformers may be connected, one in each main, so that the secondary current of one traverses the coil a and the difference of the secondary currents of the other two traverses a single coil b. Fig. 5 shows a voltage-measuring instrument or relay in which the. phase transformation is effected by a transformer ABCD of the Scott type. Fig. 7 shows an induction type relay or ammeter having a single magnet with windings a, b, b' connected as shown, the coils b, b' being in opposition. The arrangement is such that each coil a, bb' acts on the currents which the other induces in the disc D. Fig. 11 shows the connections of a wattmeter or wattmeter relay. The threephase pressure is transformed into two-phase by a Scott transformer S, the pressure coil a being fed by one of these phases. The series coils b, b<1> are reversely wound and are connected to transformers T1, T2, T3 through reactances S1, S1 and resistances r1, rl<1>.The resistances and reactances may be so regulated that the couple acting on the disc is proportional to the active, reactive, or complex power. Fig. 12 shows a wattmeter with two pressure coils a, a<1> fed from a, Scott transformer S, a current coil b connected to two transformers T1, T2 so as to be fed by a current proportional to the difference between the currents in the mains 1, 2, and a current coil b<1> fed from a transformer T3 with a current proportional to that in the main 3. In a modification, Fig. 13, the pressure coils consist of two reversely wound pairs of coils aa<1>, a<1>a1<1> connected to the mains through resistances r, r1<1>, r2<1> and inductances S, S1<1>, S2<1> Specification 258,570 is referred to.
