Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
187 words
A fluid handling installation comprising, a container for fluid, said container having an upper portion for normally containing relatively hot fluid and having a lower portion for normally containing relatively cold fluid, and said container having a connection opening therethrough, an integral fitting for connection with the container, said fitting having a pair of nested tubes transversely spaced apart for receipt of fluid therebetween, an outer one of said tubes being connected with said connection, and said tubes having first open portions opening within the same said portion of said container and said tubes further having second open portions sealed from each other and connected in circuit with a source of relatively hot fluid for delivery to said container and for receiving the relatively cold fluid from said container, the first open portion of said inner tube being spaced longitudinally outwardly from and opening in a direction away from the first open portion of said outer tube to retard direct intermixing of fluid passing through said first open portions, and the second open portion of said outer tube being between the open portions of said inner tube.
Claim 2
Dependent Claim
187 words
A fluid handling installation comprising, a container for fluid, said container having an upper portion for normally containing relatively hot fluid and having a lower portion for normally containing relatively cold fluid, and said container having a connection opening therethrough, an integral fitting for connection with the container, said fitting having a pair of nested tubes transversely spaced apart for receipt of fluid therebetween, an outer one of said tubes being connected with said connection, and said tubes having first open portions opening within the same said portion of said container and said tubes further having second open portions sealed from each other and connected in circuit with a source of relatively hot fluid for delivery to said container and for receiving the relatively cold fluid from said container, the first open portion of said inner tube being spaced longitudinally outwardly from and opening in a direction away from the first open portion of said outer tube to retard direct intermixing of fluid passing through said first open portions, and the second open portion of said outer tube being between the open portions of said inner tube.
Claim 3
Dependent Claim
44 words
An installation as set forth in claim 1 in which said container is a tank and said connection is a normal drain connection of the tank, and said outer tube has a third open portion communicating with normally closed drain means for said tank.
Claim 4
Dependent Claim
73 words
An installation as set forth in claim 1 in which said container is a hot water tank, said first open portion of said inner tube is a hot water inlet into said tank, said first open portion of said outer tube is a cold water outlet from said tank, and said second open portions of said outer tube and said inner tube communicate, respectively, with an inlet and an outlet of said source.
Claim 5
Dependent Claim
82 words
An installation as set forth in claim 3 in which said tank is part of an automatic water heater including heating means for the water, said source is an auxiliary source of heat for the water, and said fitting opens into said lower portion of said tank so that hot water entering said tank through said fitting mixes with the cold water in said lower portion of said tank before mixing with the hot water in said upper portion of said tank.
Claim 6
Dependent Claim
71 words
An installation as set forth in claim 4 in which said tank has a relief valve opening into said upper portion so that the hot water entering the tank through said inner tube and mixing with the cold water in the lower portion of the tank prevents the hot water in the upper portion of the tank from becomming abnormally over heated, thereby effectively preventing premature actuation of said relief valve.
Claim 7
Dependent Claim
45 words
An installation as set forth in claim 5 in which in normal installation of said tank said connection is a drain connection in a lower portion of the tank and said outer tube has a third open portion communicating with drain means for said tank.
Claim 8
Dependent Claim
19 words
An installation as set forth in claim 6 in which said source of hot water is a solar collector.
Claim 9
Dependent Claim
23 words
An installation as set forth in claim 6 in which said source of hot water is a condenser of an air conditioning unit.
