Abstract
This disclosure is directed to a backpack comprising a frame with straps and surrounding side wall for easy attachment on a diver. A first gas storage tank stores either oxygen or air, which is input through an inlet line. With a pressure regulator, it delivers a flow of gas to feed the diver while diving. As the pressure drops in the gas tank, a secondary source of oxygen is then operated and delivers a flow of oxygen to the diver so that the diver is able to receive supplemental oxygen stored in the gas storage tank formed by electric current flowing through a pair of spaced terminals. The terminals form oxygen by disassociation of water. The oxygen is bubbled upwardly in a chamber, pass though a hydrophobic valve, delivered into the gas storage tank, and supplements the oxygen supply.
Claims14
A backpack for a diver which comprises:
- (a) a diver-supported mounting frame;
- (b) an oxygen storage tank for receiving a charge of oxygen therein;
- (c) a gas line extending from the oxygen storage tank for providing oxygen to a diver;
- (d) an oxygen generator on the mounting frame for generating oxygen from the electrolysis of water admitted into the oxygen generator while the backpack is underwater, wherein the generated oxygen is delivered into the oxygen storage tank;
- and
- (e) a hydrogen storage tank and a backpack expansion chamber having a closed condition and an opened condition wherein said closed condition is collapsed and said expansion chamber expands to change the buoyancy of said backpack by admitting hydrogen to the expansion chamber from the hydrogen storage tank.
A backpack for a diver comprising:
- (a) a diver-supported mounting frame;
- (b) an oxygen storage tank for receiving a charge of oxygen therein;
- (c) a gas line extending from the oxygen storage tank for providing oxygen to a diver;
- and
- (d) an oxygen generator on the mounting frame for generating oxygen from the electrolysis of water admitted into the oxygen generator while the backpack is underwater, wherein the generated oxygen is delivered into the oxygen storage tank;
- (f) wherein said oxygen storage tank has an output through a pressure regulator comprising means for responding to a specified pressure for the oxygen storage tank and, upon reaching the specified pressure, operating the oxygen generator;
- and
- (g) and further comprising an external inlet line coupled to the oxygen storage tank, and wherein the oxygen storage tank is adapted to receive an external charge via the external inlet line prior to use of the backpack on a diver in water.
