  • Jig-type textile finishing apparatus
    Patent number: 5913904
    Abstract: In the jig type textile finishing method and apparatus of the invention, the textile material (19) passes through a heated treatment bath (20) and is rolled alternately in one direction and in the opposite direction with high frequency or microwave electromagnetic waves (24) being applied to said textile material (19) while it is being rolled in and/or out. The power of the waves is determined, as a function of the optimum temperature for the reaction that is to be implemented, in such a manner as to maintain the temperature of the assembly (5, 6) constituted by the rolled-in textile material and the bath in which it is impregnated substantially equal to or greater than said optimum temperature.

  • Device for the physicochemical separation of constituents of a fluid
    Patent number: 5885453
    Abstract: Apparatus for physicochemical separation and filtering constituents of fluids having a flexible leak-tight or semipermeable casing which tightly envelopes a filter material and inlet and outlet pipes for passing a fluid through the casing in contact with the filter material. The casing is made in a flat profile that can be formed into various shapes such as spirals, ribbons or the like.
