[Class 38 (iv).] In an installation of resistor furnaces the rating of all furnaces on load is reduced immediately the last of the furnaces or the last battery of furnaces is switched on. Relays g<3>, g<4> are maintained energized by auxiliary contacts h, Fig. 3, in contactors H controlling the furnace units until the last contactor is closed whereupon the connections of the resistances are modified to reduce the rating of all the furnaces and reduce. In the system shown the resistance elements of each pair of furnaces are normally connected in double star to threephase mains but the relays change this to a delta connection of series pairs of resistances. In a modification, for two furnaces, Fig. 2, the auxiliary contacts on the contactors are dispensed with and the relays 9<3> are connected across the points X, X<1> so as to be de-energized when the second furnace is switched on. The contacts in the systems shown are controlled by thermostatic temperature regulators and relays J.

Abstract: 828,193. Selsyn systems. BRITISH THOMSON-HOUSTON CO. Ltd. July 13, 1956 [July 13, 1955], No. 20354/55. Class 40 (1). [Also in Group XXXV] In a selsyn system having a polyphase secondary winding and an energized single-phase primary winding at the transmitter, the receiver has a polyphase primary (stator) supplied as usual from the transmitter secondary and a rotor magnetized solely by the current in the stator windings, such rotor having a winding short-circuited on itself and no external connections, so as to provide unequal reluctances about quadrature axes, e.g. by the presence of a short-circuited winding. Two alternative rotors are shown at B and C (Fig. 1), the former being of the salient pole type with axial bars 6 interconnected by end plates to form a single turn lying in the central plane of the poles. Rotor C is cylindrical with a uniform air-gap between it and the stator and in this case the short-circuited winding is a single-phase distributed winding to give the same number of poles as in the stator. Each rotor has stable zero positions 180 degrees apart. The stability is improved by inserting a rectifier (shunted by a capacitor) into one or more of the leads connecting the polyphase windings of the transmitter and receivers, thus introducing a D.C. component (Fig. 3, not shown).
