Marine units

摘要

A marine unit for location on the sea bed has a cylindrical body and legs which are connected to the body by a pivot adjacent one end of the body. Each leg has a toothed member which engages a common worm driven by a motor. The legs are connected by webs of net. The body and nets nest within the legs for storage, the legs are partly opened for the descent, and are opened fully when the unit reaches the sea bottom to support the unit with its axis approximately vertical.
