Abstract
Abstract Method of controlling the temperature of a tape element in a tape run utilizing a tape support element having a surface elongated in the direction of the tape run and for coaction with a surface of the tape element, the tape support surface having a tape-receiving part spaced from a tape delivery part, which method includes controlling the temperature of the tape support surface. The method includes the steps of intimately supporting the tape element by the support element, and introducing a relatively small quantity of a temperature-exchange liquid between the aforementioned elements in proximity to the tape receiving part to spread by capillarity in a thin film toward the tape delivery part. Such spreading of the thin liquid film is enhanced by moving the tape element toward the delivery part of the support.

Claim 1
Independent Claim
163 words
A METHOD OF CONTROLLING THE TEMPERATURE OF A TAPE ELEMENT IN A TAPE RUN FOR A TEMPERATURE-RESPONSIVE CHEMICAL REACTION OF SUBSTACES SUPPORTED ON SAID TAPE, UTILIZING A TAPE SUPPORT ELEMENT HAVING A TAPE SUPPORT SURFACE ELONGATED IN THE DIRECTION OF THE TAPE RUN, SAID TAPE SUPPROT SURFACE HAVING A TAPE-RECEIVING PART SPACED FROM A TAPE-DELIVEY PART THEREOF, COMPRISING: INTIMATELY SUPPORTING SAID TAPE ELEMENT BY SAID SUPPORT ELEMENT, WITH THE SURFACE OF SAID TAPE ELEMENT OPPOSING SAID SUPPORT SURFACE, RELIEVING SAID SUPPORT SURFACE LONGITUDINALLY THEREOF TO LIMIT ADHERENCE OF SAID TAPE ELEMENT TO AID SUPPORT ELEMENT, CONTROLLING THE TEMPERATURE OF SAID SUPPORT SURFACE FOR SAID TEMPERATURE-RESPONSIVE REACTION, INTRODUCING A RELATIVELY SMALL QUANTITY OF A TEMPERATUREEXCHANGE LIQUID BETWEEN SAID ELEMENTS IN PROXIMITY TO SAID TAPE-RECEIVING PART TO SPREAD BY CAPILARITY IN A THIN FILM IN THE DIRECTION TOWARD SAID TAPE-DELIVERY PART, AND MOVING SAID TAPE ELEMENT IN A DIRECTION TOWARD SAID TAPEDELIVERY PART, THEREBY ENHANCING THE SPREADING OF SAID THIN LIQUID FILM IN SAID DIRECTION.

Claim 3
Dependent Claim
24 words
A method as defined in claim 1, further including holding down said tape element on at least a portion of said filmed support surface.
Claim 4
Dependent Claim
26 words
A method as defined in claim 1, wherein: said introduction of said liquid is along a dimension extending in a direction transversely of said tape element.
Claim 5
Dependent Claim
40 words
A method as defined in claim 1, wherein: said introduction of said liquid is by a wick extending from a source of said liquid, said wick being in contact with said tape element along a transverse dimension of the latter.
Claim 6
Dependent Claim
60 words
A method as defined in claim 1, wherein: said introduction of said liquid is by a wick extending from a source of said liquid, said wick being in contact with said tape element along a transverse dimension of the latter, said wick also being in contact with an edge of said support surface along a dimension transversely of said surface.
Claim 7
Dependent Claim
25 words
A method as definEd in claim 1 wherein: said controlling of the temperature of said support surface is for controlling the application of heat thereto.
Claim 8
Dependent Claim
27 words
A method as defined in claim 1, wherein: said controlling of the temperature of said support surface is for controlling the application of a cooling effect thereto.
Claim 9
Dependent Claim
16 words
A method as defined in claim 1, wherein: said movement of said tape element is intermittent.
Claim 10
Dependent Claim
20 words
A method as defined in claim 5, further including holding down said tape element at each side of said wick.
Claim 11
Dependent Claim
170 words
IN APPARATUS FOR CONTROLLING THE TEMPERATURE OF A TAPE ELEMENT IN A TAPE RUN, COMPRISING: A SUPPORT ELEMENT HAVING A TAPE-SUPPORTING SURFACE ELONGATED IN THE DIRECTION OF THE TAPE RUN FOR COOPERATION WITH A SURFACE OF THE TAPE ELEMENT, SAID SURFACE HAVING A TAPE-RECEIVING PART SPACED FROM A TAPEDELIVERY PART THEREOF, MEANS FOR DIRECTING THE TAPE RUN CLOSELY OVER SAID SURFACE, MEANS CONTROLLING THE TEMPERATURE OF SAID SUPPORT SURFACE, MEANS FOR INTRODUCING A RELATIVELY SMALL QUANTITY OF A TEMPERATURE-EXCHANGE LIQUID BETWEEN SAID ELEMENTS IN PROXIMITY TO SAID TAPE-RECEIVING PART TO SPREAD BY CAPILLARITY IN A THIN FILM IN A DIRECTION TOWARD SAID TAPE-DELIVERY PART, AND MEANS MOVING SAID TAPE ELEMENT IN A DIRECTION TOWART SAID TAPE DELIVERY PART, THEREBY ENHANCING THE SPREADING OF SAID FILM IN SAID DIRECTION: THE IMPROVEMENT WHEREIN SAID SUPPORT SURFACE IS PROVIDED WITH A PLURALITY OF TAPE-SUPPORTING LANDS INTERMEDIATE SAID TAPE-RECEIVING PART AND SAID TAPE-DELIVERY PART, SAID LANDS BEING ARRANGED LENGTHWISE OF SAID SUPPORT ELEMENT IN SPACED RELATION TO EACH OTHER TRANSVERSELY OF SAID SUPPORT ELEMENT.
