Abstract: The invention concerns a hollow electrical conductor (1; 19; 22; 23) which can be cooled to extremely low temperatures, the conductor being fitted with an inlet for gases cooled to such temperatures, in the liquid or gaseous state, and an outlet for the gases. The invention calls for at least one hose element (5; 24) to be fitted in the hollow conductor (1; 19; 22; 23), the hose element being connected up to the gas supply and having perforations (6) to allow the gas to pass through the hose wall. The hollow conductor (1; 19; 22; 23) is conveniently surrounded by a jacket (8) or the whole unit housed in an enclosure (12). The conductor can be in the shape of a coil, or any other shape. It is particularly suitable for use as an induction coil in an induction furnace for heating, keeping hot or melting metallic materials. Preferred gases are nitrogen, helium, a freon or ammonia.

Abstract: Mica-wrapped wires for fire-resistant cables have an unusually low degree of overlap in the mica tape wraps, which unexpectably produces a smoother external profile while retaining an acceptable degree of fire protection. Two layers of glass-cloth-backed mica tape, preferably with a polymer film overlying the cloth, are preferably applied with their respective (low) overlaps staggered. This smoother wrapping is especially effective when thin (less than 0.8 mm) polymer coatings are to be extruded over the wrapped wire.

Abstract: A heat-proof lead wire for high DC voltages, on whose conductor an insulation cover made of a polyolefine resin composition is formed. The polyolefine resin composition is a flame-retarded resin mixture of a polyethylene whose crystalline component has a melting point higher than 125 °C and an ethylen-alpha olefine copolymer. The mixture contains as an essential component a monomer having carbon-carbon unsaturated bond in the molecular. The insulation cover formed of the resin composition is irradiated with ionizing radiation. Thereby, the heat-proof lead wire for high DC voltages has a vertical flame retardency (VW-1) of the UL standard and the characteristic of temperature rating below 125 °C.

Abstract: The present invention provides a ribbon cable (30) for conductingAC power and digital data signals. The ribbon cable includes a plurality of spaced, parallel, wire conductors arranged in a row, the conductors including power conductors (34) adaptable for conducting AC power and data conductors (36) adaptable for conducting digital data signals. A pliable insulating material (38) holds together and electrically insulates the conductors. Conductive material (42), such as a conductive foil or conductive plastic, is disposed either on or inside the insulating material to shield the electromagnetic interference generated by the transmitted AC power from the data conductors. The ribbon cable is then folded in a protective outer jacket (46) so that the conductive material is disposed substantially between the power conductors and the data conductors. This maximizes the electromagnetic interference shielding of the conductive material.

Abstract: An article of manufacture formed at least partly from copper, e.g. an electrical wire, has an adherent electrically insulating refractory layer deposited thereon preferably by a sputtering process. The article is also provided with an intermediate metal layer of thickness of at least 1.1 micrometres that acts either as a barrier to diffusion of copper or oxygen or has a modulus lower than that of copper. Alternatively more than one intermediate layer may be present in which case thinner layers may be used. The articles may be used as circuit or signal integrity cables and exhibit improved high temperature performance.

Abstract: An electrical wire comprises a metallic electrically conductor and an insulating mineral layer which is electrolytically formed on the conductor from a micaceous mineral and which includes a polymeric binder that has been co-deposited on the conductor from a polymer latex. Preferred latex binders include styrene/butadiene/styrene rubbers, polyvinyl acetate, acrylyic copolymers and polyvinylidine chloride. The use of a latex binder enables the micaceous mineral coating to be dried quickly during manufacture of the wire and enables hydrophobic binders to be employed.

Abstract: An electrical wire comprises an elongate electrical conductor and an insulating mineral layer electrolytically formed on the conductor from a chemically delaminated weathered mica, the mineral forming the mineral layer having a dominant x-ray reflection at approximately 10 Angstroms characteristics of the mica basal spacing. The chemically delaminated weathered mica layer is able to adhere well to the electrical conductor and exhibits good electrical insulating properties at high temperatures. The wire is capable of functioning for long periods at very high temperatures e.g. during a fire, due to the presence of the weathered mica layer.
