Abstract
Abstract The fuel used is concentrated hydrogen peroxide which has high energy content and has a simple decomposition into water and oxygen. It is stored in an expulsion tank and responsive to control temperature is fed through a warmup heat exchanger to a catalyst reactor where it breaks down into steam and hot oxygen. This passes through a main heat exchanger where it heats a heat transfer medium being recirculated by a pump through the apparatus being served and then again passes through the warmup heat exchanger to preheat the incoming hydrogen peroxide fuel. In a more complex form, the hot water or steam and hot oxygen drive a turbine motivating the pump; the water is removed from the oxygen to permit the latter to be used for breathing purposes; and a substantially constant buoyance is maintained by an oxygen filled bellows in the expulsion tank.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
95 words
An underwater heat generator wherein the improvement comprises means confining a body of hydrogen peroxide, a catalyst reactor for breaking down such hydrogen peroxide into a hot fluid composed of oxygen and water, a main heat exchanger, means conducting said hydrogen peroxide from said body through said catalyst reactor and the resulting hot fluid through said main heat exchanger, means conducting a heat transfer medium through said main heat exchanger in heat exchange relation with said hot fluid, and means conducting said heat transfer medium from said main heat exchanger to the apparatus being served.
Claim 2
Dependent Claim
95 words
An underwater heat generator wherein the improvement comprises means confining a body of hydrogen peroxide, a catalyst reactor for breaking down such hydrogen peroxide into a hot fluid composed of oxygen and water, a main heat exchanger, means conducting said hydrogen peroxide from said body through said catalyst reactor and the resulting hot fluid through said main heat exchanger, means conducting a heat transfer medium through said main heat exchanger in heat exchange relation with said hot fluid, and means conducting said heat transfer medium from said main heat exchanger to the apparatus being served.
Claim 3
Dependent Claim
24 words
An underwater heat generator as set forth in claim 1 wherein said body of hydrogen peroxide is in excess of about 65 percent concentration.
Claim 4
Dependent Claim
37 words
An underwater heat generator as set forth in claim 1 additionally including thermostat means responsive to internal temperatures of said apparatus being served for varying the rate of flow of said hydrogen peroxide to said catalyst reactor.
Claim 5
Dependent Claim
45 words
An underwater heat generator as set forth in claim 1 additionally including a warmup heat exchanger and means passing the hydrogen peroxide flowing to said catalyst reactor through said warmup heat exchanger in heat exchange relation with said hot fluid leaving said main heat exchanger.
Claim 6
Dependent Claim
26 words
An undeRwater heat generator as set forth in claim 1 wherein the water and oxygen from said warmup heat exchanger is vented to the ambient water.
Claim 7
Dependent Claim
49 words
An underwater heat generator as set forth in claim 1 wherein said means confining a body of hydrogen peroxide comprises an expulsion tank having at least one wall movable to increase and decrease the volume thereof, and means biasing said wall to decrease the size of said expulsion tank.
Claim 8
Dependent Claim
99 words
An underwater heat generator as set forth in claim 1 wherein said means confining a body of hydrogen peroxide comprises an expulsion tank, a piston head in said expulsion tank, a cylindrical diaphragm connected at one end to said piston head and at its other end to a central part of the interior of said expulsion tank to provide a first chamber containing said body of hydrogen peroxide and a second chamber vented to the ambient water, and means biasing said piston to reduce the size of said first chamber and to increase the size of said second chamber.
Claim 9
Dependent Claim
69 words
An underwater heat generator as set forth in claim 7 including a bellows in said first chamber connected at one end to said expulsion tank and at its other end to said piston head and supplied with oxygen to provide a void volume varying in size directly with the amount of hydrogen peroxide left in said first chamber thereby to provide substantially constant buoyancy of the apparatus during operation.
Claim 10
Dependent Claim
31 words
