Abstract

1,090,757. Buoyant ropes. DUNLOP RUBBER CO. Ltd. Aug. 10, 1964 [Aug. 27, 1963; Jan. 18, 1964], Nos. 33802/63 and 2302/64. Heading D1T. [Also in Division F2] A buoyancy device 1, e.g. for hoses, pipes, cables, hawsens or mooring lines comprises two or more complementary shell portions 3, 4 of a rigid synthetic resin, e.g. of polyvinyl chloride, polyethylene, polypropylene, polystyrene or of an acrylonitrile/butadiene/styrene composition, shaped so that the shell portions may be assembled about part of a pipe 2 to be buoyed up, the assembled device containing a buoyant foam material, e.g. polyurethane or expanded polystyrene. As shown, shells 3, 4 surround pipe 2. Each shell has at its edge a pair of diametrically opposed recesses 7, 8 each recess being defined by one of a series of bead edges 9. The pipe passes through the circular aperture formed by the opposed recesses in the shells. The shells are held together by rubber bands 18 which hook round ridges 16 formed in the outer surface of the shell. The space between the pipe 2 and the inner surface of the shell is filled with buoyant material. Fig. 6 (not shown) illustrates a device in which one shell has a skirt and the mating shell has an edge which fits within the skirt.
