Abstract: 1,174,208. Pipe joints. BENTELERWERKE A.G. 31 May, 1968 [14 June, 1967; 8 Jan., 1968; 17 Feb., 1968], No. 26159/68. Heading F2G. A pipe-connector 7 has right- and left-handed threads 2, 3 so that pipes 4, 5 are drawn together by rotation of the connector the union being sealed by a sleeve 8 whose ends are inserted into the pipes and which has a central head 9 which expands radially when axially compressed to seal against the inner surface of the connector. The head may be protected by endrings on the pipes (12 and 13 in Fig. 2, not shown) or by lining the inner edges of the pipes as at 14 with copper or brass. The connector and sealing sleeve have the same coefficient of expansion, and both are preferably of steel, the sleeve being hardened, if desired. As shown in Fig. 4, the inner periphery of the connector may have a plastic, preferably P.T.F.E., sealing ring 15 inserted to improve the seal against the head. Moreover the threads of the pipes bite into the ring 15. If desired, separate sealing rings lying in grooves in the connector on either side of the joint may be used to additionally seal each thread.

Filed: 1955-09-16
Abstract: 771,219. Control of A.C. motors. GENERAL ELECTRIC CO. Sept. 16, 1955 [Sept. 16, 1954], No. 26605/55. Class 38(3) When a split phase motor is started, current is supplied to both the running and starting windings 2, 3, since contacts 10. 14, are both closed. A resistance heater 7 is also energized, by the line voltage in parallel with the winding 3, and, after a predetermined period, the heater expands to open the starting contacts 10. Normally, the motor continues to run with the heater 7 connected in a closed circuit including a resistance heater 9 and starting winding 3 in which is induced a speed-responsive voltage sufficient to hold the contacts 10 open. If the motor stalls or stops, however, the heater 7 is de-energized and contracts to close the contacts 10 and re-start the motor. An overload bimetal strip 12 has a heater 11, in the power supply-line, which is aided by the heater 9 in series with the starting winding 3. Under stalled conditions, the heater' 9 carries a heavier current than when the motor is operating normally with the starting contacts 10 open, so that the overload contacts 14 are opened at a lower value of line current when the motor is stalled.
