Abstract
Abstract The tank wall is provided with a cylindrical collar in which a perforated tube base is mounted; the base having a set of tubes passing through in gas-tight relation. A thin sheet metal membrane is secured peripherally on the tube base to form an enclosed gas-tight chamber through which the tubes pass. The membrane is also perforated to permit passage of the tubes in a gas-tight relationship. The enclosed chamber permits monitoring of the imperviousness of the connections between the tubes and the tube base.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
The combination of a tank wall, a tube base connected in gas-tight relation to said tank wall, a thin sheet-metal membrane peripherally connected with said tube base in gas-tight manner to define an enclosed gas-tight chamber therebetween, a set of tubes extending through said tube base, said chamber and said membrane and being connected to said tube base and said membrane in gas-tight relation, a cylinder mounted on said tube base in surrounding relation to said tubes and a plate secured to said cylinder, said plate having apertures for guiding said tubes therethrough.
Claim 2
Dependent Claim
93 words
The combination of a tank wall, a tube base connected in gas-tight relation to said tank wall, a thin sheet-metal membrane peripherally connected with said tube base in gas-tight manner to define an enclosed gas-tight chamber therebetween, a set of tubes extending through said tube base, said chamber and said membrane and being connected to said tube base and said membrane in gas-tight relation, a cylinder mounted on said tube base in surrounding relation to said tubes and a plate secured to said cylinder, said plate having apertures for guiding said tubes therethrough.
Claim 3
Dependent Claim
24 words
The combination as set forth in claim 1 which further includes a sleeve of S-shape cross-section securing each respective tube to said tube base.
Claim 4
Dependent Claim
30 words
The combination as set forth in claim 2 wherein each sleeve is connected to a respective tube at a point close to the connection of said tube to said membrane.
Claim 5
Dependent Claim
34 words
The combination as set forth in claim 1 wherein said membrane is disposed parallel to said tube base and wherein a check-line is connected to said membrane to detect pressure variations in said chamber.
Claim 6
Dependent Claim
21 words
The combination as set forth in claim 1 wherein said membrane is disposed on an outer surface of said tank wall.
Claim 7
Dependent Claim
19 words
The combination as set forth in claim 1 wherein said membrane has a circular undulation surrounding each said tube.
Claim 8
Dependent Claim
30 words
The combination as set forth in claim 1 which further comprises a cylindrical collar mounting said tube base on said tank wall, said tube base being welded to said collar.
