Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
58 words
A heat transfer system comprising: at least three one-piece plates disposed in a spaced radiating axial manner from the axis of the heat transfer system, each of said plates having a plurality of holes disposed therein; a plurality of wound tube coils passing through the holes of said plates; and means fixing said tube coils in said plates.
Claim 2
Dependent Claim
58 words
A heat transfer system comprising: at least three one-piece plates disposed in a spaced radiating axial manner from the axis of the heat transfer system, each of said plates having a plurality of holes disposed therein; a plurality of wound tube coils passing through the holes of said plates; and means fixing said tube coils in said plates.
Claim 3
Dependent Claim
32 words
A heat transfer system as set forth in claim 1 further comprising a cylindrical body disposed on the axis of the heat transfer system, said plates being secured to said cylindrical body.
Claim 4
Dependent Claim
38 words
A heat transfer system as set forth in claim 1 wherein said means is mounted on one of said plates for moving another of said plates relative thereto whereby said tube coils are held in fixed relation therein.
Claim 5
Dependent Claim
21 words
A heat transfer system as set forth in claim 3 wherein said means moves said plates angularly relative to each other.
Claim 6
Dependent Claim
21 words
A heat transfer system as set forth in claim 3 wherein said means moves said plates axially relative to each other.
Claim 7
Dependent Claim
33 words
A heat transfer system as set forth in claim 1 wherein said means alters the relative positions of said tube coils relative to each other to fix said tube coils in said plates.
Claim 8
Dependent Claim
69 words
A heat transfer system as set forth in claim 6 wherein said means is a bar, said bar being positioned between radially adjacent tube coils axially of the heat transfer system, said bar having a dimension perpendicular to said adjacent tube coils greater than the initial spacing between said adjacent tube coils whereby said bar is braced against said adjacent tube coils upon alteration of the relative positions thereof.
Claim 9
Dependent Claim
22 words
A heat transfer system set forth in claim 7 wherein said bar has a plurality of recesses receiving said adjacent tube coils.
Claim 10
Dependent Claim
18 words
A heat transfer system as set forth in claim 1 wherein said means is mounted on said plates.
Claim 11
Dependent Claim
43 words
A heat transfer system as set forth in claim 9 wherein said means includes a plurality of wedges, each of said wedges being secured to a plate and being disposed in wedging relation between a pair of adjacent coils of said tube coils.
Claim 12
Dependent Claim
20 words
A heat transfer system as set forth in claim 10 wherein a tack weld secures said wedge to a plate.
Claim 13
Dependent Claim
39 words
A heat transfer system as set forth in claim 1 wherein each said plate has a plurality of wedge-shaped holes receiving said tube coils, each said coil being in contact at two points with the walls of each hole.
Claim 14
Dependent Claim
56 words
A heat transfer system as set forth in claim 12 wherein said means includes a wedge positioned between a pair of coils of a tube coil adjacent to a pair of wedge-shaped holes, said wedge having a wedge surface on each side thereon in contact with a coil whereby each coil is supported at three points.
Claim 15
Dependent Claim
23 words
A heat transfer system as set forth in claim 13 wherein each pair of wedge-shaped holes have broad ends thereof in facing relation.
Claim 16
Dependent Claim
38 words
A heat transfer system as set forth in claim 13 wherein said wedge surface and the wall of each wedge-shaped hole adjacent the narrow end of said wedge form an angle more than twice the angle of friction.
Claim 17
Dependent Claim
65 words
A heat transfer system as set forth in claim 1 wherEin each said plate has a plurality of slots receiving said tube coils and a pair of flaps extending into opposite ends of said slot forming wedge surfaces in resilient bearing contact with a coil, and said means includes a wedge disposed across each slot between the coils passing therethrough in contact with said coils.
Claim 18
Dependent Claim
38 words
A heat transfer system as set forth in claim 16 wherein each wedge has a pair of oppositely disposed transverse flaps, each flap resiliently bearing on a coil to form a three-point support with said pair of flaps.
Claim 19
Dependent Claim
57 words
In a heat exchange device an improved mounting arrangement for tubing, said improvement comprising, a plurality of plates having a plurality of substantially circular openings formed therein, an elongated annular member supporting the plates, said plates extending substantially radially of the member, and a plurality of helically coiled tubes each threadably mounted through some of the openings.
Claim 20
Dependent Claim
