Abstract
Abstract A temperature control device for a body comprises a member which includes a tube integral with or in efficient thermal contact with the body, a piston within the tube and means whereby its position therein may be controlled, and means for introducing heat exchange medium into the tube on the side of the piston remote from the body and means for removing it therefrom. Advantageously the heat exchange medium passes through the piston during its circulation and is brought into intimate contact with the wall of the tube. The device described is particularly applicable to bodies the temperature of which has to be controlled during rotation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
65 words
A temperature control device for a body comprising a member including a tube in operative thermal contact with said body, a piston located within said tube, means for introducing a heat exchange medium into the tube on the side of the piston remote from said body and removing said heat exchange medium therefrom, and means to control the position of the piston within the tube.
Claim 2
Dependent Claim
65 words
A temperature control device for a body comprising a member including a tube in operative thermal contact with said body, a piston located within said tube, means for introducing a heat exchange medium into the tube on the side of the piston remote from said body and removing said heat exchange medium therefrom, and means to control the position of the piston within the tube.
Claim 3
Dependent Claim
32 words
A temperature control device as claimed in claim 1 in which the body, the temperature of which is sought to be controlled and said member are arranged to be capable of rotation.
Claim 4
Dependent Claim
43 words
A temperature control service as claimed in claim 1 in which the piston includes channel means circulating said heat exchange medium within said piston, and means bringing said heat exchange medium into intimate contact with the wall of the tube during such circulation.
Claim 5
Dependent Claim
29 words
A temperature control device as claimed in claim 1 in which the walls of said tube are of greater thickness adjacent said body and of lesser thickness remote therefrom.
Claim 6
Dependent Claim
16 words
A temperature control device as claimed in claim 4 in which the tube walls are tapered.
Claim 7
Dependent Claim
22 words
A temperature control device as claimed in claim 4 in which tube walls decrease in thickness by a series of Discrete steps.
Claim 8
Dependent Claim
44 words
A temperature control device as claimed in claim 3, further comprising means to circulate said heat exchange medium through said piston from the side of said piston remote from said body, and extracting means to thereafter remove said heat exchange medium from said piston.
