    • 895,763. Capacitors. TELEGRAPH CONDENSER CO. Ltd., and HARRISON, R. J. Feb. 28, 1961 [May 26, 1960], No. 18640/60. Class 37. A cylindrical capacitor has a tubular casing of thermoplastic material, e.g. of polystyrene, closed at one or each end by a composite disc, consisting of an outer layer of rubber forming at its periphery a fluid-tight seal with the casing and an inner layer of relatively rigid material, the end or ends of the casing being turned over to bear on the rubber layer. In the form shown, the thermoplastic casing 1 is formed with a shoulder 2 and an aperture 3 in its closed end. A capacitor element 7, preferably a rolled electrolytic having a flexible lead 6 and a lead 9 is inserted into the casing and is secured by a rivet 11 to the composite disc of rubber 12 and " Bakelite " (Registered Trade Mark) or aluminium, for high temperature operation. The rubber disc is of a larger diameter than either the rigid disc or the open end of the casing to ensure an effective fluidtight seal. After insertion of the element 7 and the composite disc a pressing tool 14 heated to a suitable temperature is applied to the end of the casing to turn it over and retain the disc. The tool may be chilled before removal to prevent deformation of the casing end by the rubber disc.

    • 740,818. Feeding fuel to shaft furnaces. HARRISON, J. Feb. 4, 1954 [Nov. 4, 1952], No. 27729/52. Class 51 (2). [Also in Group XXX] In a lime kiln having a hopper top 22 feeding preheated lime into the main shaft 25 through a diametrical throat 28 in counter-current to ascending waste gases, coal is charged into each of the two spaces 31 formed by the natural slope 30 of the lime by a pneumatically fed pipe 38 movably mounted in openings 32 formed in the kiln shaft. The nozzle 33 of the pipe is mounted on springs 35 in the opening 32, the rear' end of the pipe being freely mounted in a sleeve 42 pivotally mounted in a bracket 43 comprising a fork 45 and pivot pins 44, the fork itself being attached by a rod 46 to a link of a sprocket chain 48. The chain 48 engages fixed sprockets 52 and 53, and movable sprockets 49 mounted on adjustable arms 50 on a frame 51, which also carries a motor 54, drive transmission 55, 56 and 57 driving the sprocket 53, a pump 40, and a pipe 34 connecting the blower to the pipe 38. Small size coal is fed continuously into the pipe 38 from which intermittent or continuous blasts of air from the pump 40 distribute it evenly over the charge slopes 30.
