Abstract: 1,088,660. Sheathing conductors by extrusion. ENGELHARD INDUSTRIES Ltd. Nov. 30, 1965 [Dec. 1, 1964], No. 50888/65. Heading B5A. [Also in Division H1] A water paste containing an oxide of aluminium, beryllium, magnesium, thorium or zirconium and the corresponding hydroxide is extruded about a thermocouple wire, dried sufficiently to permit handling, and a tubular sheath of malleable metal swaged into firm contact with the coated wire. The coated wire is fired to dehydrate the hydroxide to oxide before or after it is placed in the sheath. When magnesium, thorium or zirconium oxide is used it is not necessary to add hydroxide to the paste since sufficient to perform its lubricating function is formed by hydrolysis of the oxide. Normally the paste is continuously extruded about a pair of thermocouple wires and couples are formed in conventional manner by cutting the resulting cable into suitable lengths and joining the pairs of wires at one end.
