Title: Motor starting circuit
IPC: H02P1/18
Filed: 1967-06-06
Abstract: 1,125,657. Control of motors. AMERICAN DISTRICT TELEGRAPH CO. 6 June, 1967 [13 June, 1966], No. 26084/67. Heading H2J. For starting a motor of a type in which the rotor may come to rest in a position in which the field windings 15, 16 are open-circuited, an auxiliary switching element automatically completes the circuit of at least one winding when the supply 17 is first switched on at 18. The switching element may be a relay or reed switch but as shown is a transistor 21 whose collector-emitter path completes the field circuit until it becomes non-conducting due to the charge which C1 acquires. C1 discharges through R2 when 18 is opened and a Zener diode 22 protects the transistor. The motor has a permanent magnet rotor carrying an eccentric contact 14 which alternately makes with 11 and 12, with the intermediate off position shown. It may be used in an automatic alarm system.

Abstract: 1,204,395. Self-limiting resistors. KLIMATECHNIK ANSTALT. 31 May, 1968, No. 26189/68. Heading H1K. [Also in Division H5] An electrical resistance material for a selflimiting heating resistor has a finely divided conductive material (such as carbon) distributed in a solid insulation, the solid insulation being chosen to have a coefficient of thermal expansion greater than that of the conductive material and to have in the desired temperature range of A.C. operation dielectric losses which are greater or no less than its losses in the temperature range between the upper end of the operating range and the softening point of the solid insulation.

Abstract: 531,066. Cable joints. SOC. ITALIANA PIRELLI. Sept. 28, 1939, No. 26792. Convention date, Jan. 20. [Class 38 (i)] A joint for cables of the kind described in Specifications 519,602 and 519,603 which are impregnated with gasogenic materials such as mineral oils which are themselves gasogenic or are rendered so by the addition of iso-octanes, iso-nonanes &c. is itself impregnated with similar materials. This has the effect of producing a gas pressure in the joint to balance the pressure of the gas produced in the cable which is thus prevented from passing into the joint. Where the pressure in the joint is to be maintained within limits gasovorous or gas-absorbing materials such as olefinic or aromatic hydrocarbons as used in the cables described in Specification 531,065 may be added.

Title: Container
IPC: B65D51/28
Filed: 1968-06-05
Abstract: 1,191,986. Container. DESIGNA G.m.b.H. 5 June, 1968 [5 June, 1967], No. 26816/68. Heading B8D. A container comprises two vessels 12, 14, each of which is provided with a chamber having an opening, co-operating releasable means (screw threads 20, 36) engaged when said container is closed and forming a conduit connecting said openings while permitting relative movement of said vessels, and separating means 16 in said conduit. The container further comprises first coupling means (plug 30 on separator 16 fitting inside annular wall 32, of vessel 14) for yieldably holding said separating means 16 in an operative position in which the plug 30 closes the opening 34 of vessel 14 and second coupling means (tube 16 fitting inside vessel 12 and having a sealing ring 24) responsive to said relative (screw-threaded) movement for moving said separating means 16 away from said operative position thereof against the restraint of said first coupling means 30, 32. In use, the separator 16 is inserted into the filled cover 14 and the combination screwed on to the filled cup 12. In the sealed position the flange 33 on the annular wall 32 closes a circular row of axial passages 28 in the transverse partition 26 in the separating means 16, thus preventing the contents of chambers 34, 18 from mixing. To mix the contents of the two vessels the threads 20, 36 are loosened a few turns and the separator 16, which is held in stronger frictional engagement with the cup 12 than with the cover 14 is slightly withdrawn from said cover 14, thus releasing the axial holes 28 from the flange 33 and allowing the contents to mix. The cup 12 may be made of glass, the cover 14 and the separating means 16 of a plastics material. In an alternative embodiment (Fig. 2, not shown), the axial passages (28<SP>1</SP>) are closed in the operative position by outwardly extending annular sealing ribs (46) integral with the plug portion (30<SP>1</SP>) of the separating means (16<SP>1</SP>) and inwardly extending annular sealing ribs (44) on the wall portion thereof, which engage opposite sides of the cylindrical wall (32<SP>1</SP>). The wall (32<SP>1</SP>) is not provided with an annular flange as in the embodiment of Fig. 1, but partially enters the passages (28<SP>1</SP>) in the operative position. The shorter section of the somewhat resilient separator tube (16<SP>1</SP>) which extends into the cup (12<SP>1</SP>) is provided with an annular, outwardly projecting integral rib (48) which is partly receivable in a conforming groove (50) in the glass wall of the cup (12<SP>1</SP>).
