Abstract
Abstract A rotatable galette for transporting threads, filaments, tapes and the like capable of being controllably heated, preferably by an internally and concentrically mounted stationary induction coil, in which the roller jacket of the galette is an outer cylindrical wall having on its inner surface a radially outwardly recessed portion adapted to receive the terminal heat-sensitive end of an elongated temperature measuring feeler gauge.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
245 words
In a thread conveying galette with a roller jacket adapted to be inductively heated and carried at its outer end by means connected to a central rotatable drive shaft mounted on a supporting frame and with means to controllably heat said roller jacket while remaining free of contact therewith including an inductive heating coil unit rigidly connected to said supporting frame and held concentrically within said roller jacket and a stationary temperature measuring feeler gauge arranged to control the amount of heat developed in said roller jacket, the improvement which comprises: a roller jacket composed of an outer cylindrical wall part which is radially outwardly recessed over at least a portion of the length of said jacket to provide a thin wall secton thereof at a location centrally of its axis where thread contact is made and (b) an inner cylindrical wall part which contains an annular slot adapted to receive only the heatsensitive terminal end of an elongated temperature gauge in a position adjacent said centrally located thin wall section, and an elongated temperature measuring feeler gauge mounted on said frame to extend parallel to the axis of rotation of said roller jacket along its inner wall surface while remaining free of contact therewith, only the heat-sensitive terminal end of said gauge being arranged to project into said annular slot where it is surrounded on three sides by the walls of the slot the walls of the slot while remaining free of contact therewith.
Claim 2
Dependent Claim
245 words
In a thread conveying galette with a roller jacket adapted to be inductively heated and carried at its outer end by means connected to a central rotatable drive shaft mounted on a supporting frame and with means to controllably heat said roller jacket while remaining free of contact therewith including an inductive heating coil unit rigidly connected to said supporting frame and held concentrically within said roller jacket and a stationary temperature measuring feeler gauge arranged to control the amount of heat developed in said roller jacket, the improvement which comprises: a roller jacket composed of an outer cylindrical wall part which is radially outwardly recessed over at least a portion of the length of said jacket to provide a thin wall secton thereof at a location centrally of its axis where thread contact is made and (b) an inner cylindrical wall part which contains an annular slot adapted to receive only the heatsensitive terminal end of an elongated temperature gauge in a position adjacent said centrally located thin wall section, and an elongated temperature measuring feeler gauge mounted on said frame to extend parallel to the axis of rotation of said roller jacket along its inner wall surface while remaining free of contact therewith, only the heat-sensitive terminal end of said gauge being arranged to project into said annular slot where it is surrounded on three sides by the walls of the slot the walls of the slot while remaining free of contact therewith.
Claim 3
Dependent Claim
63 words
A galette as claimed in claim 1 wherein said roller jacket consists of an integral inductively heatable cylindrical metal wall having said thin wall section turned out from its inner end up to said location centrally of its axis and having said annular slot axially recessed in the offset face of said inner cylindrical wall part where it joins said thin wall section.
Claim 4
Dependent Claim
49 words
A galette as claimed in claim 1 wherein said roller jacket consists of an outer inductively heatable cylindrical metal walL as said thin wall section extending over the length of the galette and an inner annular bushing composed of an electrically well conductive material as said inner wall part.
Claim 5
Dependent Claim
91 words
A galette as claimed in claim 1 wherein said roller jacket is radially outwardly recessed only at said central location of its axis of rotation to form said annular slot, and said temperature measuring feeler gauge has an elongated member extending parallel to the axis of rotation of said roller jacket along its inner surface and a terminal end member bent radially outwardly into said annular slot, with means to rotate said leg member about its longitudinal axis and locking means to hold said terminal end member in said recessed portion.
Claim 6
Dependent Claim
43 words
A galette as claimed in claim 4 wherein the radially outwardly recessed portion of said roller jacket is formed by at least one annular bushing of an electrically well conductive material lining the inner surface of an outer inductively heatable cylindrical metal wall.
Claim 7
Dependent Claim
29 words
A galette as claimed in claim 5 wherein said temperature measuring feeler gauge is rotatably and lockably mounted onto the stationary base of the core of said induction coil.
Claim 8
Dependent Claim
69 words
A galette as claimed in claim 5 wherein said temperature measuring feeler gauge has an elongated leg member extending through a plurality of radial supporting arms of the induction coil core and said radially recessed portion of said roller jacket is located in the center up to a point near the outer end of heated roller jacket as measured longitudinally of the roller axis outwardly from the supporting frame.
Claim 9
Dependent Claim
105 words
A galette as claimed in claim 1 wherein said outer cylindrical wall part is composed of an inductively heatable metal and is radially outwardly recessed to provide said thin wall section over its length from said supporting frame at least up to said central location, and said inner cylindrical wall part includes a plurality of annular bushings composed of an electrically well conductive material lining said thin wall section in abutting axial relationship, one of said bushings having a substantially smaller annular dimension and being positioned at said central location so as to form a radially projecting annular slot in said inner cylindrical wall part.
