Abstract: A self-contained solder delivery device comprises a housing, a quantity of solder together with flux and a pressuring means for forcing the solder from the housing. The device can be used in a connector for use in connecting the conductors of electric power cables.

Abstract: A seal is provided around one or more supply lines, such as pipes, wires or cables, extending through an aperture in a bulkhead. A heat recoverable tubular article having a radially extending flange is recovered onto the supply line. A resilient annular member is held in sealing engagement against the face of the flange. Fittings are positioned over the recovered article to sealingly engage the assembly to the bulkhead aperture.

Abstract: Radially shrinkable sleeves for covering joints and terminations in high voltage cables are made by radially uniform machining of an extrudate comprising an insulating layer and at least one other layer which is conductive or semi-conductive or exhibits stress control properties. Expansion of the sleeve can be effected before or after machining. Novel shrinkable sleeves which are obtainable by this method include an insulating layer which comprises at least one tapered section in which its internal diameter increases gradually from a first diameter to a second diameter.
