Contact spring sets of electromagnetic relays have bifurcated ends considerably more resilient than their longer non-bifurcated portions and supports for the ends of the bifurcated parts of the fixed contacts adjacent contact surfaces thereof. Figs. 1 and 3 show a contact spring arrangement including, normally open (1, 2), normally closed (3, 4) and changeover contacts (5, 6, 7) in which the bifurcated ends of the springs are shaped so that fixed contacts 2, 3, 5 and 7 rest on shoulders 13, 14, 16 and 18 of a stationary support 8 and movable contacts 1, 4 and 6 rest on shoulders 20, 23 and 25 of an actuator 9. The arrangement may include a make-before-break changeover contact set (Figs. 2 and 4, not shown), in which the movable contact has double contact points. In Fig. 13 the movable contact actuator 34 is situated between the bifurcated contact arms and extends between the limbs of a U-section stationary contact support 33. Fig. 14 shows a stationary contact support spring 62 engaging the bifurcated end of the spring 61. Contact surfaces may be coated with rhodium.

Abstract: 528,715. Impregnating cables. FRASER & CO., Ltd., W. J., CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., PEEL, F., and VINCENT, R. S. May 13, 1939, No. 14325. Addition to 514,374. [Class 140] In the process of impregnating cables and like articles described in the parent Specification, the article is removed through an outlet including a viscosity gland which consists of a closely fitting member, e.g. a bell-mouthed tube sealed by a viscous liquid such as the impregnating liquid itself. Means may be provided for cooling the hot impregnating, liquid in the viscosity gland. A further modification comprises the use of a U-tube sunk below atmospheric datum to effect impregnation under pressure. Means, for example, an electrically-heated tube, may also be provided to heat the air surrounding the dry gland at the inlet in order to reduce leakage. As shown, a cable passes from a treatment zone or zones over a pulley through an elongated pipe 3 under vacuum and over a pulley 4 through viscosity glands 5, 6 connected by a vessel 7. Liquid leaking through the gland is passed by a pump 8 into a pressure zone 9 whence the cable emerges through similar glands 10, 11, and vessel 12 provided with a pump 13. Instead of passing through pressure zone 9 the cable may emerge through a tank open to the atmosphere.

Abstract: 1,168,312. Manufacturing semi-conductor devices. ELEKTROMAT VEB. 31 March, 1967, No. 14715/67. Heading H1K. During the manufacture of semi-conductor components laminar discs 2 are removed from a container 1 in which they are stacked, either in an ordered or a disordered manner, by means of a suction pipe 3 to which is imparted a shaking motion. Any discs which adhere to the selected disc, e.g. by electrostatic force, are thrown back into the container 1 by this motion. The selected disc may then be transferred to an alloying mould where it is deposited, e.g. by means of compressed air. In a modification several vacuum pipes are mounted on a single vacuum head for selection of a number of discs arranged in a regular array within a magazine. Vibration is imparted to the pipes from a common source, and the pipes are mounted within the head so as to yield axially to a certain extent, thereby minimizing the risk of breakage. It is stated to be known to select discs by suction from a tiltable container, the inside wall of which is provided with suction arms.
