Abstract
379,711. Reciprocating motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and CLINKER, R. C., Tryrn, Bilton, near Rugby. March 4, 1931, No. 6738. [Class 35.] Electrical means for producing mechanical movement comprise a circuit energized by alternating current including a closed core reactance 3 in series with a condenser 4 and means such as a movable core or armature 2 arranged to cause a change in the inductance of the circuit, the electrical conditions of the circuit being such that a variation of the inductance from a minimum value at which the current is high, to a predetermined higher value ensures a sudden drop in the current and vice versa, and these sudden changes of current are utilized to sustain an oscillatory or reciprocating movement of the core or armature. It is explained in the Specification that the closed core of the reactor approaches saturation at high current values with consequent diminution of the coil inductance so that with varying applied voltage or with varying reactor admittance, the current varies according to the characteristic shown in Fig. 2. In the form shown in Fig. 4, the actuating coil 1 is separate from the main reactor, whereas in Fig. 5 an armature 7 is mounted to move in the leakage field from the portion 6 of the core which works at a higher flux density than the remaining portion 8. The oscillating movement may be converted into rotation. Specification 253,110, [Class 35, Dynamo-electric generators &c.], is referred to.
