Abstract
Abstract A rotary processor useful in mixing, conveying, and heating or cooling a fluid material. Interchangeable subassemblies each comprise a helical coil permanently affixed at each end to a terminal block. The terminal blocks of each subassembly are removably fastened at a preselected orientation to two polygonal segments of a rotatable shaft. The polygonal segments are rotated relative to one another. A portion of the shaft and the subassemblies are supported within a housing having an inlet and an outlet for flow of the material to be processed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
224 words
A fluid material rotary processor comprising: a plurality of interchangeable subassemblies, each said subassembly including two terminal blocks and a helical coil having two ends, each of said ends being sealingly and permanently affixed within one of said terminal blocks, each said coil having a coil axis; a shaft including a shaft axis, a first segment and a second segment, said segments each having exterior edges forming in cross section a polygon, said edges of said first segment being angularly offset with respect to said edges of said second segment, said axes of said coils being parallel to said shaft axis; means for removably mounting said subassemblies to said edges of said segments such that said coils are mounted aside said shaft and certain of said subassemblies are axially staggered along said shaft with respect to other of said subassemblies; a housing having a fluid material inlet and outlet; means for supporting and rotating said segments and affixed subassemblies within said housing; said coils entering said terminal blocks at an entry angle with respect to said shaft axis, said entry angle being equivalent to the helix angle of said respective coil, and said certain subassemblies being staggered along said shaft with respect to other of said subassemblies by a distance equivalent to the pitch of said coils divided by the number of said subassemblies.
Claim 2
Dependent Claim
224 words
A fluid material rotary processor comprising: a plurality of interchangeable subassemblies, each said subassembly including two terminal blocks and a helical coil having two ends, each of said ends being sealingly and permanently affixed within one of said terminal blocks, each said coil having a coil axis; a shaft including a shaft axis, a first segment and a second segment, said segments each having exterior edges forming in cross section a polygon, said edges of said first segment being angularly offset with respect to said edges of said second segment, said axes of said coils being parallel to said shaft axis; means for removably mounting said subassemblies to said edges of said segments such that said coils are mounted aside said shaft and certain of said subassemblies are axially staggered along said shaft with respect to other of said subassemblies; a housing having a fluid material inlet and outlet; means for supporting and rotating said segments and affixed subassemblies within said housing; said coils entering said terminal blocks at an entry angle with respect to said shaft axis, said entry angle being equivalent to the helix angle of said respective coil, and said certain subassemblies being staggered along said shaft with respect to other of said subassemblies by a distance equivalent to the pitch of said coils divided by the number of said subassemblies.
Claim 3
Dependent Claim
104 words
The processor of claim 1 wherein said shaft includes a hollow portion and a solid drive portion of circular cross section, said coils are hollow, said terminal blocks have a passage therethrough and said segments have apertures aligned with respective passages, and further comprising means for flowing a heat transfer fluid from a reservoir serially through said shaft, aperture, passage, coil, another passage, another aperture, and said shaft back to said reservoir, the mating edges of said segments and bottom surfaces of said terminal blocks being compatibly machined and further comprising a sealing gasket positioned between each respective machined mating edge and bottom surface.
Claim 4
Dependent Claim
46 words
The processor of claim 2 wherein said edges form in cross section a regular polygon having the same number of sides as the number of said subassemblies and wherein said coils are welded to said terminal blocks and said terminal blocks are bolted to said segments.
Claim 5
Dependent Claim
30 words
The processor of claim 1 and wherein each said coil is interconnected to said respective terminal blocks and segments at a position along said helical coil closest to said shaft.
