Abstract
Abstract The specification describes a thermal treatment roll, e.g. for heating or cooling a textile yarns etc., wherein a rotor is mounted on a stator which is provided with a heating or cooling means. Between the stator and rotor is a connecting element of a solid, heat-conducting lubricating material, e.g. a ring or rings of sintered metal impregnated with a lubricating oil.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
A thermal treatment roll comprising, in combination: a. a hollow rotor having an inner and an outer periphery; b. a stator disposed inside said rotor and having an outer periphery; c. a heating means in said stator; and d. a connecting element composed at least partly of a solid heat conducting, lubricating material in direct contact with the greater part of the outer periphery of the stator and in direct contact with the greater part of the inner periphery of the rotor, effective to provide a conductive heat path between said stator and rotor.
Claim 2
Dependent Claim
94 words
A thermal treatment roll comprising, in combination: a. a hollow rotor having an inner and an outer periphery; b. a stator disposed inside said rotor and having an outer periphery; c. a heating means in said stator; and d. a connecting element composed at least partly of a solid heat conducting, lubricating material in direct contact with the greater part of the outer periphery of the stator and in direct contact with the greater part of the inner periphery of the rotor, effective to provide a conductive heat path between said stator and rotor.
Claim 3
Dependent Claim
22 words
A roll as defined in claim 1, wherein the connecting element forms at least part of the external periphery of the stator.
Claim 4
Dependent Claim
22 words
A roll as defined in claim 1, wherein the connecting element forms at least part of the internal periphery of the rotor.
Claim 5
Dependent Claim
21 words
A roll as defined in claim 1, wherein the connecting element is a sintered metal ring impregnated with a lubricating oil.
Claim 6
Dependent Claim
48 words
A roll as defined in claim 1, wherein said connecting element comprises an inner, an outer and central coaxial sintered metal rings, impregnated with a lubricating oil, said inner ring contacting said outer periphery of said stator and said outer ring contacting the inner periphery of said rotor.
Claim 7
Dependent Claim
41 words
A roll as defined in claim 1, and further comprising a temperature sensitive probe located within said connecting element, and regulating means connected to said probe effective to control said heating means in response to temperature variations sent by said probe.
Claim 8
Dependent Claim
92 words
A thermal treatment roll comprising, in combination: a. a hollow rotor having an inner and outer periphery; b. a stator disposed inside said rotor and having an outer periphery; c. a cooling means in said stator; and d. a connecting element composed at least partly of solid heat conducting lubricating material in direct contact with the greater part of the outer periphery of the stator and in direct contact with the greater part of the inner periphery of the rotor, effective to provide a conductive heat path between said stator and rotor.
Claim 9
Dependent Claim
92 words
A thermal treatment roll comprising, in combination: a. a hollow rotor having an inner and outer periphery; b. a stator disposed inside said rotor and having an outer periphery; c. a cooling means in said stator; and d. a connecting element composed at least partly of solid heat conducting lubricating material in direct contact with the greater part of the outer periphery of the stator and in direct contact with the greater part of the inner periphery of the rotor, effective to provide a conductive heat path between said stator and rotor.
