Filed: 1952-05-13
Abstract: 716,453. Induction motors. HUTCHINS ELECTRIC CO., Inc. May 13,1952 [Oct. 8, 1951], No. 12150/52. Class 35 A self-starting single-phase induction motor has a pair of parallel connected stator windings at least part of each winding being disposed adjacently in the same slots and in mutually inductive and magnetic additive relation to each other. In the form shown the stator carries a main winding b, c composed of two sections in quadrature, and a starting winding a in parallel with the section b. A relay 6, 7 serves to connect the starting winding when the motor is first switched on and to disconnect it when the current in the main windings b, c falls to a sufficiently low level. The starting winding a has comparatively few turns of thick wire and consequently draws a heavy starting current. The mutual flux linkage with winding b in the same slots reduces and retards the phase of the current flowing in the main winding. The resultant current flowing in the quadrature axis is thus displaced sufficiently to produce a startng torque. In a modification, both windings are distributed round the stator in such a way that there is substantial overlap between the two windings. Specifications 680,137, 704,626 and 704,627 are referred to.

Title: An improved process for removing layers from used films or film waste by means of alkali lye without special mechanical treatment
IPC: C08J11/06
Filed: 1937-04-29
Abstract: Gelatine, albumen, and other coating layers are removed from used films or film waste by treating the films for a few minutes with a solution containing 8 per cent or more of caustic alkali at a temperature of about 60 DEG  C.  The time of treatment is shorter the higher the alkali concentration, and it may be 1--3 minutes for an alkali concentration of 15 per cent.  Gelatine layers even when hardened or provided with a varnish coating are so completely dissolved away by the alkali treatment that a separate removal by brushes, scrapers, knives, or other mechanical device is not necessary.  Albumen and other foundation layers are also dissolved away by the treatment.  The celluloid film material thus recovered is free from cloudiness.  The process may be applied to waste kinematograph and other photographic films, and to films containing no image layer.  Specifications 331,006, [Class 2 (iii)], and 364,845, [Group XV], are referred to.
