[Also in Division G1] A movable-magnet float switch has a sealed magnetic reed contact device 50 influenced by a magnet 54 which is moved about its pivot 58 by a magnet moved by a float (Fig. 1, not shown), so that the magnet 54 is moved in one direction due to the proximity of one pole of the float magnet and in the other direction due to the proximity of the other pole of the float magnet. The magnet 54 is retained in its extreme positions by its attraction to steel split pins 64, 66 one of which may be omitted if the assembly is mounted so that the magnet 54 is gravity biased to one position. A plurality of such assemblies may be operated by a common float magnet (Fig. 1). The reed contact device may be replaced by a magnetically sensitive semi-conductor or resistor (not shown).

1,004,738. Semi-conductor devices. APPLEBY & IRELAND Ltd. Aug. 7, 1963 [May 8, 1962], No. 17717/62. Heading H1K. A thermocouple is produced by causing the ends of a pair of wires projecting from the end of a metallic sheath, through which they pass and from which they are insulated, to touch one another and then uniting them by electron beam welding. As shown, Fig. 2, a thermocouple cable comprises two conductors 12, 13 of dissimilar metals, supported and insulated by a packing of metalli coxide 14, contained in a stainless steel sheath 11. The cable is drawn thro ugh a die to the required size and one end is inserted in a bore in a bush 21 and stripped to expose the conductors. The cable is mounted in a vacuum chamber and an electron beam 15 is used to weld sheath 11 to bush 21. As shown, Fig. 5, the ends of the conductors are bent into contact and then welded together, a ferrule 17 of Iconel (Registered Trade Mark) or stainless steel is welded to the sheath at 18, and the assembly is sealed by welding a plug 19 into the end of ferrule 17, all the joints being made by electron beam welding. Ferrule 17 may be filled with insulating material before inserting plug 19. In use the flange 22 of bush 21 may be welded to the casing of the apparatus. Specification 940,850 is referred to.
