Abstract: 687,208. Inductor alternators. DYNAMO & MOTOR REPAIRS, Ltd., and TYLER, G. T. March 1, 1951 [March 3, 1950], No. 5433/50. Class 35. An inductor alternator for use as a signal tone generator has two axially spaced stator and rotor units on the same shaft, each stator and rotor unit having a pair of diametrically opposed teeth or slots which are mutually staggered by the same angle, the exciting coils encircling a stator tooth of each section so that it has no voltage induced in it. In one form, Fig. 1, for producing symmetrical impulses, the stator is divided into axially spaced parts having diametrically opposed poles 5a, 5b respectively, the rotor parts being provided with corresponding teeth 6a and slots 6b. Since the stator and rotor parts are equally staggered, the flux in one stator pole rises as the other falls and so the total flux passing through the field coil 7 remains steady. In a modification, Fig. 3, for producing asymmetrical pulses, the stator parts are as before, but each rotor consists of two displaced half-cylinders to produce oppositely facing shoulders 9c on the two rotors.

Abstract: 937,265. Rotary piston engines, pumps and compressors. J. P. RENSHAW. Feb. 17, 1961 [Feb. 24, 1960], No. 5970/61. Class 110 (2). A rotary piston I.C. engine comprises a housing A, Fig. 1, rotatably mounting a power disc B on a shaft 20 and three identical housings C equally spaced about the housing A and each housing a valve disc D rotatable about an axis in a plane at right angles to that of the disc B. The disc B is formed with recesses E, Fig. 2B, providing combustion chambers, and peripheral gear teeth 29, 40 and each disc D with recesses F, Fig. 4, providing compression chambers, and peripheral gear teeth 45, 46 co-operable with the gear teeth 40, 29 respectively to synchronously rotate the disc D with respect to the disc B. The teeth 40, 29, 45, 26 all being of the same pitch. A charge of combustible fuel and air sucked in through an intake 58, Fig. 4, is rotated counterclockwise until the leading edge 59 of a recess F co-operates with the trailing edge 60, Fig. 3, of a recess E to compress the charge. On continued rotation of the discs the charge is transferred through a groove 72 in the side of the disc D to a compression manifold 70 whose outlet 55 in the bottom of the housing A is at this time closed by the disc B. The charge is then ignited by a spark-plug 53, and on the opening of the outlet 55, on further rotation of the disc B, transferred to a recess F whence the expanding gases act on the leading edge 38 of the recess F to drive the disc B, spent gases from a previous charge being driven out through an exhaust port 80. A feed-back loop pipe 95 on each casing C connects the recess 72 associated with one recess F to the other recess F to feed-back any charge not passed to the compression manifold 70. Dirt traps (not shown) located above and below the disc B in the housing A where it adjoins the housing C collects any dirt formed on the gear teeth which eventually escapes into the recesses E and F and through the exhaust port 80. The engine with modifications in which the spark plug and similar parts are removed may be used as a pump or compressor, the shaft 21 then being driven by an external power source.
