Abstract
Abstract A deep underwater sphere is constructed of a plurality of spherical sections. Each of these sections has a spherical shaped frame made of a plurality of radially arranged trusses with an outer metal shell and an inner metal shell attached to the frame. Adjacent sections are interconnected by connecting selected trusses from each of the sections together. The space between the inner and outer metal shells is filled with a high density mixture which serves to impart resistance to compressional forces placed on the sphere and additionally serves as a ballast for securing the proper specific gravity for sinking of the sphere.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A deep underwater sphere comprising: a plurality of spherical sections; each said section having a spherical shaped frame made of a plurality of radially arranged trusses, an outer metal place and an inner metal plate, said inner and outer metal plates are both made of spherical shaped plates; selected said trusses from each of said sections being connected to selected said trusses of an adjacent said section; said plates being arranged on a respective one of said trusses frames such that both said inner and outer plates each extend over said respective frame at one end and such extended portion overlaps said trusses of said adjacent section and are welded to said adjacent section; and a concrete mixture filling the space between said inner and outer plates for serving to impart resistance to compressional forces placed on the sphere and serving as a ballast for securing the proper specific gravity for sinking of the sphere.
Claim 2
Dependent Claim
155 words
A deep underwater sphere comprising: a plurality of spherical sections; each said section having a spherical shaped frame made of a plurality of radially arranged trusses, an outer metal place and an inner metal plate, said inner and outer metal plates are both made of spherical shaped plates; selected said trusses from each of said sections being connected to selected said trusses of an adjacent said section; said plates being arranged on a respective one of said trusses frames such that both said inner and outer plates each extend over said respective frame at one end and such extended portion overlaps said trusses of said adjacent section and are welded to said adjacent section; and a concrete mixture filling the space between said inner and outer plates for serving to impart resistance to compressional forces placed on the sphere and serving as a ballast for securing the proper specific gravity for sinking of the sphere.
Claim 3
Dependent Claim
24 words
An arrangement as defined in claim 1 wherein each said frame is substantially triangular shaped and said sections are substantially identical to one another.
Claim 4
Dependent Claim
17 words
An arrangement as defined in claim 1 wherein said selected trusses are connected by being bolted together.
Claim 5
Dependent Claim
46 words
An arrangement as defined in claim 1 wherein said outer plate is a spherical shaped plate member of 1 inch thickness, said inner plate is a spherical shaped plate member of 3/4 inch thickness and the spacing between said inner and outer plates is 30 inches.
Claim 6
Dependent Claim
51 words
An arrangement as defined in claim 1 wherein said sections utilized for forming the upper half of the sphere each have a polar shaped frame portion at their vertex side and said polar shaped frame portions are interconnected for forming a substantially circular opening in the upper end of the sphere.
Claim 7
Dependent Claim
20 words
An arrangement as defined in claim 5 further comprising at least one inlet port and at least one outlet port.
