Abstract
Abstract A system for supplying controlled temperature warm water to the space between a human body and a protector extending over the body comprising a source of pressurized water; a heat exchanger connected to the source to receive and heat the source water and discharge water at temperature T 1 ; a mixing valve connected to the heat exchanger to receive the water discharge from the heat exchanger, the mixing valve having a cold water inlet and being operable to mix cold water with the water at temperature T 1 received from the heat exchanger, thereby to provide and discharge a mixed water stream at controlled temperature T 2 , where T 2 is less than T 1 ; a plenum chamber connected with the mixing valve to receive discharged water at temperature T 2 for mixing with warm water in the plenum chamber; and a duct extending from an outlet at the plenum chamber to deliver warm water to the space.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
233 words
In a system for supplying controlled temperature warm water to the space between a human body and a protector extending over the body, the combination comprising: (a) a source of pressurized water, (b) a heat exchanger connected to said source to receive and heat the source water and discharge water at temperature T 1 , (c) a mixing valve connected to the heat exchanger to receive the water discharge from the heat exchanger, the mixing valve having a cold water inlet and a discharge outlet and being operable to mix cold water with the water at temperature T 1 received from the heat exchanger, thereby to provide and discharge via said outlet a mixed water stream at controlled temperature T 2 , where T 2 is less than T 2 , (d) a separate buffer tank defining a plenum chamber connected with the mixing valve via said discharge outlet to receive discharged water at temperature T 2 for mixing with warm water in the plenum chamber, (e) a duct extending from an outlet positioned at the plenum chamber to deliver to said space water which consists of water in said plenum chamber mixed with water from said mixing valve, (f) and wherein said source comprises a pump, and including an internal combustion engine driving said pump, said engine having a hot exhaust gas outlet connected with said heat exchanger to heat water therein.
Claim 2
Dependent Claim
233 words
In a system for supplying controlled temperature warm water to the space between a human body and a protector extending over the body, the combination comprising: (a) a source of pressurized water, (b) a heat exchanger connected to said source to receive and heat the source water and discharge water at temperature T 1 , (c) a mixing valve connected to the heat exchanger to receive the water discharge from the heat exchanger, the mixing valve having a cold water inlet and a discharge outlet and being operable to mix cold water with the water at temperature T 1 received from the heat exchanger, thereby to provide and discharge via said outlet a mixed water stream at controlled temperature T 2 , where T 2 is less than T 2 , (d) a separate buffer tank defining a plenum chamber connected with the mixing valve via said discharge outlet to receive discharged water at temperature T 2 for mixing with warm water in the plenum chamber, (e) a duct extending from an outlet positioned at the plenum chamber to deliver to said space water which consists of water in said plenum chamber mixed with water from said mixing valve, (f) and wherein said source comprises a pump, and including an internal combustion engine driving said pump, said engine having a hot exhaust gas outlet connected with said heat exchanger to heat water therein.
Claim 3
Dependent Claim
42 words
The system of claim 1 wherein said mixing valve has an associated thermostat for control of mixing so as to produce T 2 discharge water, and including a control valve in series with said duct whereby the user may operate said valve.
Claim 4
Dependent Claim
13 words
The system of claim 1 including said protector to which said duct extends.
Claim 5
Dependent Claim
12 words
The system of claim 3 wherein said protector comprises a wet suit.
Claim 6
Dependent Claim
13 words
The system of claim 1 including a dredge carrying said pump and engine.
Claim 7
Dependent Claim
35 words
The system of claim 1 wherein T 2 has a range of about 100° F. to 110° F., there being a conduit to conduct said 100° F. to 110° F. water to said plenum chamber.
Claim 8
Dependent Claim
26 words
The system of claim 3 including a control valve in said duct extending from the plenum chamber to said protector, to which the duct is connected.
Claim 9
Dependent Claim
27 words
The system of claim 1 including a second pump driven by said engine, and a gold particle recovery suction line to which the second pump is connected.
Claim 10
Dependent Claim
172 words
In a system for supplying controlled temperature warm water to the space between a human body and a protector extending over the body, the combination comprising: (a) a source of cold water, and a source of hot water, (b) a mixing valve connected to said sources to receive cold water and hot water therefrom, the water in the mixing valve being pressurized, the mixing valve having a discharge outlet and operating to mix the cold and hot water and to discharge same via said outlet at desired temperature T 2 , (c) a separate buffer tank defining a plenum chamber connected with the mixing valve via said discharge outlet to receive discharged water at temperature T 2 for mixing with warm water in the plenum chamber, (d) a duct extending from an outlet positioned at the plenum chamber to deliver to said space water which consists of water in said plenum chamber mixed with water from said mixing valve, (e) and a control valve in recess with said duct, near said space.
Claim 11
Dependent Claim
172 words
