Abstract: A dielectric heat generator in which radio frequency energy derived from a radio frequency oscillator is divided into two separate ratio frequency components which are equal but out of phase with each other. Each component is applied to a separate electrode. In one embodiment the two components are essentially 180.degree. out of phase and each component is applied to a different one of two electrodes that are positioned in tandem and facing a third electrode which is coupled to ground. In a second embodiment, the components are essentially 180.degree. out of phase and each component is applied to a different one of two electrodes that are facing each other and spaced apart from each other. In a third embodiment, the two components are essentially 90.degree. out of phase and are applied to an arrangement of finger electrodes.

Abstract: A method is described for producing a multicolor printed web material such as a carpet substantially without spoilage of production web material during a start-up of a printing process employing a plurality of dyes applied in different patterns. A lead carpet is formed which is non-receptive to the dyes. The lead carpet is attached to the production carpet and the dye patterns tested on the lead carpet. After correction, if necessary, for print misalignments and other dye printing station operations, the production carpet is printed. Both lead and production carpets are processed to fix the dyes and remove excess non-fixed dyes. The removal step results in cleaning of the lead carpet on which the dyes were not fixed. The lead carpet is then disconnected and made available for another print start-up.

Abstract: Space print head draw rolls for use as part of a dye application print station for the application of dye paste to yarn comprises first and second counter-rotating rolls in mechanical engagement with each other, whereby the yarn is gripped between the rolls and advanced therethrough. The first roll includes a core and a wire mesh sheath covering the exterior surface of the core. The second roll includes a core having a resilient covering on its exterior surface.

Abstract: A deweaving apparatus for deweaving a fabric tape by separating and removing a weft filling yarn from a plurality of warp yarns. Control means are provided for sensing breakage of the warp yarns and weft yarn, as well as knots, splices and tangles in the tape, and in response to any such condition in the tape, stops the operation of the apparatus. Along with these means of automating the deweaving process, and greatly reducing operator attention required, a special divergence guide is fitted which accelerates loosening of the weft yarn over a very short path, thereby providing significant reduction in floor space required for the deweaving process.
