Abstract: 966,593. Mounting dynamo-electric machine rotors. GENERAL ELECTRIC CO. Nov. 17, 1961, No. 41238/61. Heading H2A. [Also in Division F2] In a bearing arrangement, a shaft 9 is mounted in sintered bearings 10, 11 and has mounted thereon a pair of annular thrust collars 20, 21 and a pair of annular star-shaped springs 24, 25. Each spring 24 or 25 is positioned intermediate the bearing 10 and the collar 20 or the bearing 11 and the collar 21, is pre-loaded to take up play, and is engaged between points by extensions 30a and 30b of the collars 20 and 21 so that the springs are rotatable by the collars. The thrust faces 27 and 28 of the bearings 10 and 11 are inclined outwardly and the thrust faces 22 and 23 of the collars 20 and 21 are arcuate in shape. Thus the springs are both slightly biased as shown in Fig. 3 when an axial force is absent and one spring is particularly biased as shown in Fig. 4 when an axial force is applied. The arcuate faces of the collars 20, 21 provide a varying fulcrum so that the effective leverage is reduced as the axial force is increased. The bearings 10, 11 are lubricated by pads 18, 19. In an embodiment, the shaft 9 carries a rotor 6 and the bearings 10 and 11 are carried by a shell 2 which also carries a stator 3.

Abstract: 417,621. Vacuum gauges. SYKES, C., 2, Dartmouth Road, Chorlton, Lancashire, WALKER, C. H., Mabrouk, Lynmouth Avenue, Flixton, near Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. May 20, 1933, No. 14667. [Class 106 (ii).] A gauge sensitive to gas pressure has a gastight casing 1 having a tubular part 2 adapted for connection to an apparatus in which the gas pressure is liable to variation, for instance vacuum apparatus. A U-shaped bimetallic strip 3 is mounted in the casing and carries a contact 10 adapted to co-operate with a contact 11 on a second bimetallic strip 12. Constant current is supplied to the strip 3 through terminals 8, 9 by means such as a barretter and the strip attains a steady temperature dependent on the heat loss by radiation and convection. The convection loss depends on the gas pressure in the casing and so if the vacuum fails the strip cools and contacts with strip 12 to energize protective, controlling, or indicating circuits. The strip 12 is bimetallic to compensate for variations in ambient temperature. If desired, the bimetallic strip may operate a visual indicator through multiplying levers and the casing would then be made transparent.

The phase control circuit 4 serves for starting the motor. The commutator 2 has three transistors 7, 8, 9 supplying respective phase windings of the motor. The triggering circuit 3 is a three stage multivibrator. The phase control circuit 4 may simply be a relaxation oscillator, Fig. 2 (not shown), having a low natural frequency for starting the motor. Above this frequency the oscillator will be synchronized with the position sensor output. Fig. 5 (not shown) illustrates a modification of the Fig. 2 circuit in which the oscillator is synchronized with the position sensor output when a transistorized switch (80, 81) is operated, this occurring when the frequency of a feedback signal from the stator winding equals the oscillator's natural frequency. Fig. 3, illustrates a modified position sensor 5 and modified phase control circuit 4. The position sensor includes two windings 78, 79 wound on saturable cores and supplies the phase control circuit through a rectifier bridge. The phase control circuit includes three threshold stages including respective transistors 53. The threshold stages respond to different levels in the output of the rectifier bridge and so feed successive signals to the input capacitors 33, 35, 37, Fig. 1, of the triggering circuit 3 which sequentially triggers the transistors 7, 8, 9.
