Title: Device for joining two tubular elements
IPC: F16L17/035
Filed: 1979-03-05
Abstract: Two tubular elements (1,2) are joined by inserting one end portion of one tubular element (2) into one end portion of the other tubular element (1). A peripheral groove (3) is provided in the outer surface of the one end portion of the tubular element (2). An elastic sealing ring (4) has a substantially L-shaped cross section formed by two parts (7, 8). One part (7) of the sealing ring extends within the groove whilst the other part (8) projects to form a peripheral flange. Upon insertion of the end portion of the tubular element (2) into the end portion of the tubular element (1) the two parts (7, 8) of the sealing ring (4) are brought into an overlapping position. The invention has the advantage that the part (7) of the sealing ring (4) in the groove (3) is not subjected to torsional moment and so it is not necessary to secure the sealing ring (4) in position. <IMAGE>

Patent GB-2042286-A (GB)
Title: A speed control-arrangement for a three-phase induction machine
IPC: H02P/
Filed: 1979-12-24
Abstract: The arrangement comprises a thyristorized speed controller. The firing pulses for the thyristors are generated in such a manner that the output voltages of the three-phase speed controller constitute a three-phase a.c. voltage system which has a controllable fundamental frequency that is lower than the supply system frequency and an amplitude which is also controllable. In this way, the speed is controlled by a frequency change without a power loss by an arrangement which involves only a low structural expenditure. A firing pulse control device is provided in which firing is effected only at the positive half-cycles during a predetermined number of supply cycles and firing is subsequently effected only at the negative half-cycles during a predetermined number of supply cycles. The firing instants during each half cycle is controllable to determine the amplitude and envelope shape of the output voltage. <IMAGE>

Patent GB-2069149-A (GB)
Title: Flow sensing device
IPC: G01F1/28
Filed: 1980-01-18
Abstract: A flow sensing device comprises a shaft (18) which is axially movable, and extends across a flow passageway (14), and carries an angled vane (16) in the passageway (14). At each side of the passageway, the shaft (18) is supported by a flexible member e.g. a diaphragm (26) bellows or bush, which also prevents the leakage of fluid from the passageway (14) beside the shaft (18). The two diaphragms (26) are of equal area, so that any static pressure within the passageway (14) does not result in a net pressure force tending to move the shaft (18) axially. No other support is provided for the shaft (18). Movement of the shaft may actuate a micro switch 66, a pneumatic switch or a flow indicator. <IMAGE>

Title: Surface-coating composition
IPC: C09D167/08
Filed: 1980-02-08
Abstract: A surface-coating composition is described which contains an aluminium compound and an alkyd resin which has low hydroxyl and acid values. The alkyd resin is prepared either by the fatty acid or alcoholysis route to obtain an intermediate alkyd resin having either a low hydroxyl value and a high acid value or a high hydroxyl value and a low acid value. The intermediate resin is treated with a monobasic acid or monohydric alcohol to reduce the hydroxyl or acid value as required to yield an alkyd resin having a hydroxyl value of about 50 mg KOH/g or less and an acid value of about 4.5 mg KOH/g or less. The composition according to the invention preferably contains 0.5 to 12% by weight of aluminium metal based on the weight of the alkyd resin solids.
