Abstract: 711,456. Differential mechanism. SCHOTT, D. E. Nov. 28, 1952 [Dec. 1, 1951], No. 30235/52. Class 80 (2) In a gearless differential, the opposed faces of two driven discs 23, 24, secured to half axles 20, have each two symmetrically-arranged intersecting circular grooves 25a, 26a, and 25b, 26b, and a driving disc 28 arranged between the discs 23, 24 has four radial slots 30, each receiving a slide 37 on the ends of which are journalled quadrants 38a, 38b having ribs slidably engaging the grooves. Two adjacent quadrants 38a engage groove 26a and the other two quadrants 38a engage groove 25a while the corresponding quadrants 38b engage grooves 26b, 25b, and 25b, 26b respectively. Normally, both discs 23, 24 rotate at the same speed as disc 28, but if one disc is restrained from rotation the other disc rotates at twice the speed of disc 28, but there is always a substantial driving torque applied to the restrained member. Each disc 23, 24 may have three or more symmetrically-arranged intersecting grooves instead of two, with the disc 28 having twice that number of slots. It is, however, possible to have the same number of slots as grooves, but this results in an unbalanced arrangement.

Abstract: 651,726. Automatic control systems for A.C. synchronous motors. MULLIGAN, J. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 21, 1947, No. 30960. [Class 38 (iv)] In a system for controlling a synchronous electric motor, the excitation of the coupled D.C. exciter is controlled in accordance with the motor load current and in accordance with the exciting current of the exciter in such a manner that the ratio of these two currents is maintained substantially constant to increase efficiency without loss of synchronism on overload. The rotor excitation of a synchronous motor M is derived from a coupled D.C. exciter E, the current in the self-excited field winding F, of which is made directly proportional to the load current of the motor by energizing one coil LC of a balanced relay BR through a three-phase rectifier R from a current transformer CT associated with the A.C. supply to the motor, the other coil EC of the relay being energized by the exciter field current. Deviation from proportionality results in operation of switch contacts C of relay BR to run a three-phase servomotor SM in the appropriate direction to restore proportionality by adjustment of an exciter field rheostat RS. Means to ensure on low load a predetermined minimum exciter excitation are referred to. The following modifications are referred to : (a) contactors, controlled by the relay, shorting sections of a resistance in series with the exciter field ; (b) a carbon pile regulator, in the exciter field circuit, controlled by the relay ; (c) a transductor having two D.C. control windings in place of the relay to control either a relay or the A.C. supply to a rectifier energizing the exciter field ; (d) a vibratory regulator in place of the relay. The Provisional Specification refers. to an exciter of the metadyne type.
