Abstract

1349135 Seismic energy generators BOLT ASSOCIATES Inc 22 Dec 1970 34064/73 Divided out of 1349134 Heading H4D A diaphragm structure for acoustically coupling a seismic source to the earth comprises a polyurethane diaphragm 6 with an annular reinforcement skirt 6A of polyurethane to restrict displacement of the diaphragm. The source may be as disclosed in the parent Specification, including an "air gun" in a rigid, liquid-filled tank 2 the base of which is formed by the diaphragm structure.
