Filed: 1958-02-06
Abstract: 824,898. Single-phase induction motors. STOLL, G., [trading as FESTO-MASCHINENFABRIK G. STOLL.]. Feb. 6, 1958 [Feb. 8, 1957], No. 3857/58. Class 35. A single-phase induction motor is rendered self-starting by means of short-circuited shading windings passing through the stator winding slots and angularly displaced relatively to the main windings one side of each main winding coil lying in the same slot as a coil-side of the shading winding. As shown for an eighteen-slot stator carrying a main winding occupying sixteen of the slots and consisting of two seriesconnected sections I, II, the short-circuited windings 41, 42 and 51, 52, i.e. occupying eight of the slots, are arranged in the same manner as the coils of the main winding but are displaced from the main windings by an angle α which is 45 degrees for the present two-pole case. The short-circuited coils are of copper or aluminium sheet, and they occupy the bottom of the slots through which they pass. By reversing the connection of coil II with respect to coil I, four-pole operation is secured. The coils of main windings I and II have stepped numbers of turns, so that the short-circuited turns have unequal voltages induced in their slot-portions. The greater voltage overcomes the lesser with the result that the effective phase-angle displacement is increased. It is stated that this so-called bifilar effect necessitates the use of main windings having even numbers of turns.

Abstract: 139,184. Zurovec, W. Dec 24, 1917, [Convention date]. Screw propellers.-In a method of making metal aircraft propeller blades, a metal bar is passed several times through a rolling-mill. The blank while passing between the profiled rolls is turned automatically about its longitudinal axis to suit the curvature of the helical surface. In the form shown, the bar 8 is secured at one end by a gripper 9 carried by a support 10 which is secured to a rack 4 reciprocated by hydraulically-operated pistons 5. The rack engages pinions 3 on the roll shafts so as to oscillate a pair of profiled spiral rolls 1. The gripper has a pinion 11 engaging a rack-bar 12, which mcves along a curved guide 13 so as to rotate and thus twist the bar to the necessary pitch. The bar is secured to the gripper and the free end introduced between the rolls when positioned so that the cross-section of the pass is slightly greater ihan that of the bar, the curved guide being displaced out of action. The guide is then replaced aud the bar given a series of short passes, and then a series of gradually increasing passes. The gripper may be longitudinally adjusted on the support 10 and the guide correspondingly adjusted so as to alter the relative positions of work and rolls to effect a preliminary rolling. The Specification as open to inspection under Sect. 91 (3) (a) states that the rack may be replaced by a chain, and also that one of the pistons may be recoil-operated, or only one used. Further, one or more pairs of rclls may be used. This subject-ma.tter does not appear in the Specification as accepted.
