Abstract

1,134,300. Fluidpressure jacks. TUBMETAL LA CELLOFIBRE. 25 April, 1967 [3 May, 1966], No. 18958/67. Heading B8J. [Also in Division F2] A jack is provided with a piston 16 having elastomeric piston rings 21 (Division F2) clamped in position by a screw-threaded device. The jack may be made wholly or partly of plastics including polystyrene and methacrylene, the latter being used when the jack is to be transparent. Covers 5, 6 may be clamped to the cylinder 2 by stays 14 or bonded thereto by use of a solvent. The piston is cushioned by seals 11, 12.
