Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
Apparatus for wet processing textile fabric in continuous loop form of the type that includes means for recirculating said fabric loop free of nip constraint and under an aspiration influence induced with an inert gas, together with an enclosure housing a chamber of J-box configuration capable of containing liquid and arranged for storing a major portion of said fabric loop while the loop is progressively withdrawn from and returned to said chamber during recirculation under said aspiration influence, and in which said chamber is additionally arranged with a throat adjacent the entrance to the J-box leg at which the fabric loop is returned and means is connected at said throat for drawing off the discharge from said aspiration influence and delivering the drawn off discharge for inducing said aspiration influence, said connecting means providing the only path of communication between said chamber and the housing enclosure therefor.
Claim 2
Dependent Claim
147 words
Apparatus for wet processing textile fabric in continuous loop form of the type that includes means for recirculating said fabric loop free of nip constraint and under an aspiration influence induced with an inert gas, together with an enclosure housing a chamber of J-box configuration capable of containing liquid and arranged for storing a major portion of said fabric loop while the loop is progressively withdrawn from and returned to said chamber during recirculation under said aspiration influence, and in which said chamber is additionally arranged with a throat adjacent the entrance to the J-box leg at which the fabric loop is returned and means is connected at said throat for drawing off the discharge from said aspiration influence and delivering the drawn off discharge for inducing said aspiration influence, said connecting means providing the only path of communication between said chamber and the housing enclosure therefor.
Claim 3
Dependent Claim
32 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 1 wherein the liquid containing capability of said chamber is sufficient to accommodate a conventionally formulated dyestuff bath.
Claim 4
Dependent Claim
24 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 1 wherein said chamber is enclosed within a pressure kier.
Claim 5
Dependent Claim
74 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 3 wherein said means for drawing off the aspiration discharge is a duct connected at said chamber throat and extending therefrom between the chamber J-box legs to a lateral opening in the enclosing pressure kier at which the suction leg of a blower included in said recirculating means is connected in communication with both said pressure kier and said duct.
Claim 6
Dependent Claim
39 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 4 wherein said recirculating means also includes a venturi at which the pressure leg of said blower is connected for inducing an aspiration influence thereat.
Claim 7
Dependent Claim
62 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 5 wherein a conduit superstructure is assembled with said kier and includes an entrance leg for receiving said fabric loop upon withdrawal from said chamber and a discharge leg for directing return of the loop to said chamber, and wherein said venturi is installed in said discharge leg.
Claim 8
Dependent Claim
36 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 6 wherein said superstructure entrance leg is equipped with extraction means operable selectively for receiving liquid from said fabric loop during recirculation.
Claim 9
Dependent Claim
44 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 3 wherein said kier is fitted with means to employ the space therein around said chamber for heat exchange purposes to control the temperature of said fabric loop during recirculation.
Claim 10
Dependent Claim
31 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 8 wherein the means to employ said kier space for heat exchange purposes is a steam injector.
Claim 11
Dependent Claim
47 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 1 wherein means is provided for injecting dyestuff into the inert gas by which said aspiration influence is induced so that the dyestuff is applied to said fabric incident to said aspiration influence.
Claim 12
Dependent Claim
41 words
Apparatus for wet processing textile fabric in continuous loop form as defined in claim 1 wherein said chamber is fitted with means for disposing a dyestuff bath in said chamber for application to said fabric during recirculation under said aspiration influence.
