Abstract: A method to form a carpet tile into a configuration for use on a stair riser. This method involves measuring the stair riser and using this measurement to score the pile on the face of a tile. The tile is then bent to a 90 angle and a nose guard adhesively placed over the bent or nose portion of the title to provide a preformed product. This product then can be taken on the job, placed into position and readily tacked or glued down to provide the stairs with a tile product which is comparable to the adjacent tiled areas and readily tacked or glued down to provide the stairs with a tile product which is comparable to the adjacent tiled areas.

Abstract: Method and apparatus to produce a plied, air textured continuous filament yarn by severing the supply yarn upon the detection of a drop in tension. When the tension in the yarn being processed drops, the position of the running yarn will be detected by a photocell unit which will actuate a cutter upon such detection to sever the yarns being supplied to the air texturing machine. The method and apparatus provide that the drop in tension has to occur for a predetermined length of time or occur a multiplicity of times before the cutter is actuated.

Abstract: A method and apparatus for treatment of relatively moving substrate materials by preheating the substrate before precise selective application of discrete, high temperature pressurized streams of fluid against the surface of the materials to impart a visual and tactile change thereto. The apparatus includes an elongate manifold for receiving heated pressurized fluid, such as air, disposed across the width of the relatively moving material and having a single slit the full width of the substrate for directing the fluid into the surface of the material. Pressurized cool fluid, such as air, is directed across selected portions of the manifold discharge slit to deflect pressurized heated air away from the substrate. The manifold is provided with cool air outlets which direct the heated air to a position upstream of the path of movement of the substrate for preheating purposes. The apparatus is further arranged and configured to enhance the visibility of faults in the substrate.

Abstract: A method and apparatus for forming and selectively interrupting one or more fluid stream which is confined within an open channel. A transverse fluid stream is introduced into the channel at a point under the stream flowing within the channel. Introduction of the transverse stream at relatively low pressure is sufficient to cause the stream within the channel to leave the confines of the channel. If the channel is directed at a target, the method and apparatus will allow intermittent and selective interruption of a fluid stream flowing within the channel and directed at the target. The source of the transverse fluid stream has an arcuate or curved outlet portion to prevent fluid from the open channel from accumulating therein.

Abstract: Fabrics are made electrically conductive by contacting the fiber under agitation conditions with an aqueous solution of an aniline compound, oxidizing agent and a doping agent or counter ion and then depositing onto the surface of individual fibers of the fabric a prepolymer of the aniline compound so as to uniformly and coherently cover the fibers with a conductive film of the polymerized aniline compound and wherein, furthermore, the oxidizing agent is a vanadyl compound whereby the reaction rate is controlled such that the prepolymer is uniformly and coherently adsorbed onto the surface of the textile material, thereby providing improved films of electrically conductive polymerized compound on the textile material.

Abstract: The process for producing patterns on ground dye colored textile fiber pile substrates, particularly wherein the pile fibers are in the form of yarns comprised predominantly of polyamide fiber, and wherein at least some of the ground dye component is at least partially color dischargeable and selected from vat, reactive, direct, acid, premetallized or mordant dyes, the process comprising contacting selected portions of the colored pile fibers with a reducing system which optionally can contain one or more reduction resistant dye or pigment materials for in situ coloring of the substrates, the contacting being characterized by jet forcing the reducing system interstitially of the pile fibers to deposit the reducing system thereon substantially below the surface thereof, and to effect the color discharge of at least a portion of the ground dye component.

Abstract: A method and apparatus for patterning a substrate wherein liquid unfixed dye is applied to the substrate in the form of a spray. One or more streams of pressurized gas such as air are then directed onto the substrate for the purpose of displacing some of the unfixed dye where the streams impinge the substrate, thereby causing a visually distinctive area on the substrate where the relative dye concentration is reduced. Resulting products are also disclosed.

Abstract: Apparatus and method to sculpture a pile fabric from a predetermined pattern by controlling the movement of the cutter by a pantograph system which employs rotary mounted carriers. The cutter arrangement employs an arrangement where the individual pile fibers or looks are bent over and then individually released so that the rotating cutter blade can sever the fiber or loop against a fixed blade to provide a clean cut of the top of the fiber or fiber loop.

Abstract: A pressure sensitive tape employing a tricot knit carrier fabric having a minimum number of weft yarns. The tricot knit carrier fabric being knit on a tricot knitting machine which employs a loop hold down bar to prevent the first three or four courses adjacent the needles of the knitting machine from breaking out when released or cast off the needles.

Abstract: A detection system is disclosed for detecting the presence of a marking material placed on a textile substrate prior to a series of dyeing and finishing steps. Following such steps, the substrate carrying the marking material is illuminated by light having a preferred wavelength of about 900 nanometers. The light is preferably absorbed by the marking material, thereby reducing the amount of light reflected from the substrate carrying the marking material and triggering an alarm. In a preferred embodiment, the marking material contains carbon particles.

Abstract: By method of dispensing vapor, preferably perfumed vapor, to the air in a room from a vapor dispensing substance, vapor is dispensed by means of an electrically controlled control device for controlling the vapor dispensation of the vapor dispensing substance, and an electrical circuit for controlling the current supply to the control device. By the fact that the electrical circuit is supplying a time controlled, gradually increasing current supply to the control device in time periods with intermediate periods of no current supply to the control device is achieved that the concentration of the vapor dispensed is kept at a constant level, until the vapor dispensation substance has been used up.

Abstract: Method and apparatus for the manufacture of a composite camouflage construction having an open mesh net substrate, and a continuous sheet overlying the substrate and bonded thereto along plural spaced lines of attachment, with lobes of the sheet cut to simulate the appearance of leaves and foliage. Apparatus and method includes a sewing station for stitching the sheet along plural spaced lines of attachment to the substrate to form open-ended pockets or channels between the sheet and substrate. The cutting station spaces the sheet from the substrate and a heated cutting wire reciprocates between adjacent lines of stiches to cut the sheet, open the channel, and use a series of loose lobes simulating the appearance of natural objects of a terrain.

Abstract: An ultra-sonic weaving machine reed cleaner in which the cleaner is moved adjacent the weaving machine and the reed is cleaned without disturbing the thread-up of the warp yarn in the reed.
