Abstract

A seismic transducer generates waves in an elastic medium and is partic. applicable to generation of i.f. shear waves. It includes a mass member having parallel hydraulic cylinders with a piston in each one. Each piston has a pair of oppositely extending rods. A frame, interconnecting the ends of the piston rods, has a base surface for engaging a surface of the elastic medium. A series of ports within the pistons and frame enables high pressure fluid to be communicated to the cylinder in such a manner as to cause simultaneous reciprocation of the pistons relative to the mass member.
