Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
In a means for sending heat downward, a pair of metallic containers one above the other and connected by a metallic tubular passageway, said passageway reaching almost to the inner bottom of the lower container and almost to the inner top of the upper container, one of said containers partially filled with liquid sulphur dioxide and all tubular and container contacts and connections permanently sealed and made leak proof so no sulphur dioxide fumes can possibly excape.
Claim 2
Dependent Claim
77 words
In a means for sending heat downward, a pair of metallic containers one above the other and connected by a metallic tubular passageway, said passageway reaching almost to the inner bottom of the lower container and almost to the inner top of the upper container, one of said containers partially filled with liquid sulphur dioxide and all tubular and container contacts and connections permanently sealed and made leak proof so no sulphur dioxide fumes can possibly excape.
Claim 3
Independent Claim
113 words
A method of sending heat downward including having an upper metallic container, and another metallic container below it, both containers connected by a metallic tubular passage way, extending almost to the top of the upper container and almost to the bottom of the lower container, all tubular and container contacts and connections permanently sealed and made leakproof so no sulphur dioxide fumes can possibly escape there from, positioning a pool of liquid sulphur dioxide in said upper container, heating said upper container thus causing said liquid sulphur dioxide to vaporize and move downward through said tubular passage way as a vapor into said lower container and condensing said vapor in said lower container.
Claim 4
Independent Claim
113 words
A method of sending heat downward including having an upper metallic container, and another metallic container below it, both containers connected by a metallic tubular passage way, extending almost to the top of the upper container and almost to the bottom of the lower container, all tubular and container contacts and connections permanently sealed and made leakproof so no sulphur dioxide fumes can possibly escape there from, positioning a pool of liquid sulphur dioxide in said upper container, heating said upper container thus causing said liquid sulphur dioxide to vaporize and move downward through said tubular passage way as a vapor into said lower container and condensing said vapor in said lower container.
Claim 5
Dependent Claim
18 words
The invention set forth in claim 2 including the return of the liquid condensate into the upper container.
