Abstract: 1419530 Magnetic switches; permanent magnets WESTINGHOUSE ELECTRIC CORP 18 Dec 1972 [11 Jan 1972] 58326/72 Headings H1N and HIP [Also in Division A4 ]  A flush-top cooking unit has a manually movable control member 18 which rests in a depression 22 provided in the non-magnetic panel 10 of the cooking unit and which is magnetically coupled to a follower member 19 located beneath the panel 10 and controlling the heating rate of an induction coil underlying visual indicia 14 provided on a ceramic plate 12 of the cooking unit. In use eddy currents induced by the induction coil in the base wall of a cooking vessel placed on the plate 12 heat the cooking vessel to effect the cooking. The control member 18 includes a multiple-pole magnetic block 24 and a high magnetic-permeability back-up plate 26 encased in a moulded plastics shell 28. The control member 18 is provided with a window 32 having an index. line (34), Fig. 5 (not shown), which overlies a heating-rate scale (Fig. 2, not shown), provided on the panel. The shell 28 has projecting skids 30 received in the depression 22. The follower member 19 associated with each control member has a multiple-pole magnetic block 42 and a back-up plate 44. The magnetic blocks 24 and 42 preferably each have three poles with the end poles half the length of the centre pole. The follower member includes a carriage 64 provided with wheels 68 which ride against the undersurface of the panel 10. The carriage 64 is supported by, and moves in unision with, a rack (60), Fig. 6 (not shown). Movement of the follower member results in rotation of pinion gears (54) and (58). The pinion gear (58) is secured to the shaft (50) of a potentiometer (56) used to control a signal voltage which in turn varies a D.C. voltage level applied to the oscillator of the induction heating coil. The pinion gear (54) operates a cam (52) which controls an on-off switch (72) which closes on movement of the control member to the "OFF" position. A spring may be provided to return the follower member to the "OFF" position when the control member is removed, for example for cleaning. The spring may be of a type in which a uniform spring force is provided irrespective of the position of the follower member. The embodiment of Fig. 8 (not shown), provides a multiplepole control magnet (78) and a multiple-pole follower magnet (80) for use where the follower member is to be directly coupled to a rotatable switch. Adjacent opposite poles are provided in the centre part of each of the magnets (78) and (80) to prevent mis-registry of the magnets. The control member (82) of Fig. 9 (not shown), has a single magnetized block (86) and a backup plate (90) which provides flux paths to convert the edge of the plate (90) into poles. The control member (82) is used with a similar follower member (84).

[Also in Divisions B2, and D1] A cushioning material is made by forming a batt of fully inflated closed cell microcellular filaments (or fibres) which have a thermoplastic adhesive deposited thereon, heating the batt to a temperature below the polymer melt temperature of the filaments sufficient to activate the adhesive and simultaneously compressing and cooling the batt to deactivate the adhesive. The volume fraction of the filamentary material in the consolidated batt is at least 0À4. The microcellular filaments may contain 6-40 g. of inflatant per 100 g. of filamentary polymer. The filamentary polymer may be polyhydrocarbon, polyether, polyvinylic, polyamide, polyurethane or polyester. The adhesive may be ethylene-vinyl acetate copolymer, ethylenemethacrylic acid copolymer ethylene-methacrylic acid-vinyl acetate terpolymer, polyester, polyolefin, polyamide, neoprene, polyurethane or natural resin. The adhesive can be applied before or after the batt is formed as an aqueous dispersion, in solution, or as a powdered solid. Talc or a silicone detergent can be applied to the batt, e.g. with the adhesive in order to silence noise on cyclic compression. The batt can be compressed by cold rolls, on engraved conveyer belts and a roll, two conveyer belts or between plates at least one of which has a diamond shaped pattern thereon. The batt can be compressed on to an article to form a protective layer around it. The batt can be bonded during the heating and compression stages or in a separate stage to a knitted, non-woven, woven or net-like fabric, foam sheets (e.g. of polypropylene) a metallic foil, paper, or a continuous polymeric film. The batt can be stitched between a scrim and a cotton fabric then heated to form a quilted effect. Microcellular filaments are prepared in Example 1 by extruding a mixture of polyethylene terephthalate, methylene chloride and trichlorotrifluoethane at 190 C. and 525 psig. The filaments are cut into staple fibre then immersed in boiling methylene chloride and perfluorocyclobutane and heated at 125 C. in an oven to inflate the filaments. Reference has been directed by the Comptroller to Specification 1,145,932.

Teeth 12...15 are provided on the ends of arms 4, 5, those at the north poles being displaced half a tooth pitch relative to those at the south poles. In operation the arms 4, 5 oscillate in opposite directions and the consequent changes in flux path through the rotor and core produce rotation of the rotor. Bumpers 26 limit transverse movement of the member 6 should the oscillator be subjected to mechanical shock. To reduce the gap between the centre of core 3 and the rotor, the member 6 may be housed in a recess in the core, Fig. 3 (not shown). The rotor may drive a clock or watch.
