Title: A process and apparatus for separating pulverulent materials
IPC: B07B7/086
Filed: 1938-10-29
Abstract: 506,488. Centrifugal separators. I. G. FARBENINDUSTRIE AKT.-GES. Oct. 29, 1938, No. 31306. Convention date, Oct. 29, 1937. [Classes 23 and 117] Pulverulent materials are sorted centrifugally in an eddy formed by a carrier fluid which travels in a chamber from periphery to centre; the coarse material leaves at the boundary of the chamber and the fine material is withdrawn axially with the carrier fluid. The form of apparatus shown has a separating chamber 1 with entry pipes 2 for the carrier fluid. The material to be separated may be supplied with the carrier fluid, or it may be supplied separately through the inlet 3. The fluid whirls with a diminishing radius and the fine material passes through the axial outlet tube 6 with the carrier, and the coarse material passes through the outlets 4 to the collecting chamber 9. The grading of the two parts separated may be varied by varying the speed or quantity of the carrier fluid by means of a pump or valve in front of the inlets 2, or by displaceable flaps 7. A diaphragm 8 may be arranged at the outlet tube 5, or adjustable openings may be provided in a part of this tube projecting into the chamber 1. The grading of the separated coarse material may be varied by admitting carrier fluid by the pipe 6 to flow in counter-current to the material flowing out through the openings 4. Specification 490,393 is referred to.

Title: Improvements in and relating to split-phase electric motors
IPC: H02K17/04
Filed: 1955-11-02
Abstract: 825,624. Winding slots for split-phase motors. GENERAL ELECTRIC CO. Nov. 2, 1955 [Nov. 5, 1954], No. 31379/55. Class 35. Relates to a split phase motor having a main winding, and a starting winding which is disconnected when the motor reaches full speed, in which the starting winding is wound to have a higher resistance than the main winding and is angularly displaced therefrom. Each pole of the main winding is provided with a pair of end slots 9 in which only the main winding is placed, and each slot 9 has a relatively deep and narrow opening 10 compared with the openings 11 for the remainder of the slots 15. The leakage flux for each slot 9 is thereby increased, so increasing the inductance and phase displacement of the main winding current. This leads to a higher starting torque without an appreciable change in the starting current of the motor.
