Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
Apparatus for the treatment of textile materials, in a bath containing as vehicles of the treating agent, at least two fluid components of different volatilities which can be separated, from which at least one is to be removed during said treatment which comprises: an enclosure for treating textile materials, means for drawing off continuously a fraction of said bath, means based upon the differential volatilities of the fluid bath components for separating the fluid bath components to be removed from said fraction, a recycling circuit ensuring re-introduction, into the treatment enclosure, of the liquid part obtained after separating bath components, regulating devices for regulating the volume of the fraction drawn off from said enclosure.
Claim 2
Dependent Claim
114 words
Apparatus for the treatment of textile materials, in a bath containing as vehicles of the treating agent, at least two fluid components of different volatilities which can be separated, from which at least one is to be removed during said treatment which comprises: an enclosure for treating textile materials, means for drawing off continuously a fraction of said bath, means based upon the differential volatilities of the fluid bath components for separating the fluid bath components to be removed from said fraction, a recycling circuit ensuring re-introduction, into the treatment enclosure, of the liquid part obtained after separating bath components, regulating devices for regulating the volume of the fraction drawn off from said enclosure.
Claim 3
Dependent Claim
16 words
Apparatus according to claim 1 wherein the means for drawing off said fraction comprises a pipe.
Claim 4
Dependent Claim
18 words
Apparatus according to claim 2 wherein the means for drawing off said fraction comprises further a thermal exchanger.
Claim 5
Dependent Claim
17 words
Apparatus according to claim 2 wherein the means for drawing off said fraction further comprises a pump.
Claim 6
Dependent Claim
26 words
