Abstract
Abstract A device for the transmission of two or more signals, such as control signals, between a rotatable member such as a roller and a fixed or stationary member, e.g. as required in textile machines for the control of heated godets or rollers which convey thread on a heated surface maintained at a predetermined temperature, said device including at least two elongated arcuate signal transmitting elements carried rotatably on an annular planar support secured to the godet or roller and preferably two stationary transmitting elements for each of the rotatably carried transmitting elements wherein at least one of the stationary transmitting elements always remains in an operative coupling position with a rotatably carried transmitting element to form an individual transmitting unit for one of the signals.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
In a device for transmitting at least two control signals between a rotatably driven roller member and an adjacent fixed member, each signal being conducted through its own individual transmitting unit, the improvement which comprises: a circular carrier frame secured to said roller member for rotation therewith about a common axis; a plurality of elongated arcuate signal-transmitting elements arranged at spaced intervals around a generally planar annular portion of said circular carrier frame and rotatably carried therewith; a plurality of stationary signal-transmitting elements positioned in a circumferential direction around said carrier frame in a number sufficient to provide at least two stationary transmitting elements for each rotatably carried transmitting element, each stationary transmitting element forming an operative individual transmitting unit when coupled with one of said rotatably carried transmitting elements and the arcuate interval between two adjacent stationary transmitting elements being greater than the arcuate interval between the adjacent end positions of two of said elongated and rotatably carried arcuate transmitting elements; and means to impart a separate signal to each individual transmitting unit through a transmitting circuit.
Claim 2
Dependent Claim
178 words
In a device for transmitting at least two control signals between a rotatably driven roller member and an adjacent fixed member, each signal being conducted through its own individual transmitting unit, the improvement which comprises: a circular carrier frame secured to said roller member for rotation therewith about a common axis; a plurality of elongated arcuate signal-transmitting elements arranged at spaced intervals around a generally planar annular portion of said circular carrier frame and rotatably carried therewith; a plurality of stationary signal-transmitting elements positioned in a circumferential direction around said carrier frame in a number sufficient to provide at least two stationary transmitting elements for each rotatably carried transmitting element, each stationary transmitting element forming an operative individual transmitting unit when coupled with one of said rotatably carried transmitting elements and the arcuate interval between two adjacent stationary transmitting elements being greater than the arcuate interval between the adjacent end positions of two of said elongated and rotatably carried arcuate transmitting elements; and means to impart a separate signal to each individual transmitting unit through a transmitting circuit.
Claim 3
Dependent Claim
93 words
A signal-transmitting device as claimed in claim 1 wherein a multiple throw switching means is connected with all of the stationary transmitting elements of one transmitting unit for sequentially switching each of said stationary elements in and out of the transmitting circuit at predeteRmined positions of the rotatably carried transmitting elements such that one stationary transmitting element in the most effective coupling position with respect to a rotatably carried transmitting element is switched in while at least the most remote of the other stationary transmitting elements of the same unit is switched out.
Claim 4
Dependent Claim
29 words
A signal-transmitting device as claimed in claim 2 wherein said switching means is operatively responsive to a sensing means for detecting the positions of the rotatably carried transmitting elements.
Claim 5
Dependent Claim
26 words
A signal-transmitting device as claimed in claim 3 wherein said sensing means is a photoelectric device which directs said multiple throw-switching means through electromechanically operated relays.
Claim 6
Dependent Claim
42 words
A signal-transmitting device as claimed in claim 3 wherein said sensing means and its operative connection to said switching means are linked with a cutout means to prevent the operation of the multiple throw-switching means while the roller member is being rotated.
