Abstract

814,328. Fluid-pressure blasting devices. HAYDEN-NILOS Ltd. Aug. 22, 1957 [Aug. 22, 1956; Dec. 22, 1956; Feb. 5, 1957; May 17, 1957], Nos. 25608/56, 39143/56, 3926/57 and 15693/57. Class 9(1) An infusion tube has a cam 26 pivotally mounted at 25 on one end of the inner of two co-axial tubes 1, 3 the cam acting on the corresponding end of the other tube to cause relative movement of the tubes so that a rubber annulus 8, mounted about the other end of the inner tube 3, is expanded or contracted radially as it is compressed or expanded axially between collars 5, 6 secured to the tubes. The degree of compression can be regulated by having a threaded end piece to the outer collar. The single rubber annulus 8 may be replaced by a pair of similar packer units.
