Deep water sound imploder

Abstract

An underwater sound imploder adapted for use in the exploration of minerals existing under the sea bed. The imploder consists of three main units, a boiler, a heat shield therefor and a bell shaped sonic device to which the boiler has delivered superheated steam. Expansion of the steam under water pressure causes the implosion. The steam condensate is pumped back into the boiler where it is recycled. The implosions occur repeatedly in the device thereby causing a succession of sonic impulses to pass through the water medium and return as echoes for detection and analysis to determine thereby the character of the reflecting object in the sea bed.
