Abstract
Abstract A body is centered within a housing and restrained from moving from such centered position by surrounding the body with a plurality of flattened like tubes positioned between the body and the interior walls of the housing and simultaneously expanding the tubes so as to center the body by filling the tubes with a hardenable material under pressure. Upon hardening of the material, the body is restrained from moving from the centered position. The method is applied particularly to the coils of an electromagnet and the beam tube of a particle accelerator so centered and restrained within a tubular electromagnet housing by hydraulically pumping an epoxy resin under a high pressure into the symmetrically spaced like tubes which are connected hydraulically in parallel and, following curing of the epoxy, capping the ends of the tubes to maintain hydraulic integrity of the system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
64 words
A method of centering and restraining a body within a housing comprising: surrounding said body with a plurality of flattened like tubes between said body and said housing; filling said tubes simultaneously with a hardenable material under pressure whereby the tubes expand to center the body within the housing; and hardening said hardenable material, thereby restraining movement of said body from the centered position.
Claim 2
Independent Claim
64 words
A method of centering and restraining a body within a housing comprising: surrounding said body with a plurality of flattened like tubes between said body and said housing; filling said tubes simultaneously with a hardenable material under pressure whereby the tubes expand to center the body within the housing; and hardening said hardenable material, thereby restraining movement of said body from the centered position.
Claim 3
Independent Claim
113 words
A method of centering and restraining a body within a housing comprising: positioning said body within said housing; positioning a plurality of flattened like tubes between said body and the interior walls of said housing, said tubes being symmetrically spaced about said body; connecting said tubes together hydraulically in parallel; hydraulically pumping epoxy resin under pressure into said tubes whereby they expand to center said body within said housing and restrain the body from moving; curing the epoxy resin to hardness while maintaining the hydraulic pressure; and capping the ends of said tubes to maintain the hydraulic integrity of the epoxy resin, thereby rigidly restraining movement of said body from the centered position.
Claim 4
Independent Claim
113 words
A method of centering and restraining a body within a housing comprising: positioning said body within said housing; positioning a plurality of flattened like tubes between said body and the interior walls of said housing, said tubes being symmetrically spaced about said body; connecting said tubes together hydraulically in parallel; hydraulically pumping epoxy resin under pressure into said tubes whereby they expand to center said body within said housing and restrain the body from moving; curing the epoxy resin to hardness while maintaining the hydraulic pressure; and capping the ends of said tubes to maintain the hydraulic integrity of the epoxy resin, thereby rigidly restraining movement of said body from the centered position.
Claim 5
Dependent Claim
68 words
The method of claim 2 wherein said housing is tubular; said body consists of a central member extending along the axis of said tubular housing and a plurality of peripheral members surrounding said central member and symmetrically spaced about the axis thereof; and said flattened like tubes are positioned parallel to the axis of said central member between the interior walls of said housing and said peripheral members.
Claim 6
Dependent Claim
63 words
The method of claim 3 wherein said central member extends through said tubular housing; said peripheral members are elongated flattened coils, said coils elongated in a direction parallel to the axis of said central member; said flattened tubes are positioned along the elongated segments of said coils; and each such elongated segment of each coil is in contact with such a flattened tube.
Claim 7
Dependent Claim
36 words
The method of claim 4 wherein said tubular housing is a ferromagnetic material, said coils are the coils of an electromagnet, and said central member is a portion of the beam tube of a particle acceleRator.
Claim 8
Independent Claim
161 words
A method of centering and restraining the coils about a central member in an electromagnet comprising: positioning said central member within the electromagnet housing, positioning said coils within said housing symmetrically about the periphery of said central member; positioning a plurality of flattened like tubes between the windings of said coils and the interior walls of said housing, said tubes being symmetrically spaced and each such tube essentially filling the space between the windings and the interior wall of said housing; connecting said tubes together hydraulically in parallel; hydraulically pumping curing epoxy resin under pressure into said tubes whereby they simultaneously expand to center the coils within the housing about said central member and restrain the coils from moving; curing the epoxy resin to hardness while maintaining the hydraulic pressure; and capping the ends of said tubes to maintain the hydraulic integrity of the epoxy resin whereby the coils are rigidly restrained and centered in the electromagnet about said central member.
Claim 9
Independent Claim
161 words
A method of centering and restraining the coils about a central member in an electromagnet comprising: positioning said central member within the electromagnet housing, positioning said coils within said housing symmetrically about the periphery of said central member; positioning a plurality of flattened like tubes between the windings of said coils and the interior walls of said housing, said tubes being symmetrically spaced and each such tube essentially filling the space between the windings and the interior wall of said housing; connecting said tubes together hydraulically in parallel; hydraulically pumping curing epoxy resin under pressure into said tubes whereby they simultaneously expand to center the coils within the housing about said central member and restrain the coils from moving; curing the epoxy resin to hardness while maintaining the hydraulic pressure; and capping the ends of said tubes to maintain the hydraulic integrity of the epoxy resin whereby the coils are rigidly restrained and centered in the electromagnet about said central member.
