Abstract: Apparatus is disclosed for controlling the position of a moving web. The web passes between a driven roll and a pair of pressure applicators that are positioned on either side of center of the web path. Edge sensors are located adjacent the driven roll and are operatively connected with the pressure applicators. Once the web misalignment is sensed, the opposite pressure applicator is actuated to apply pressure against the web. The driven roll, preferably a scroll roll, then drives the web in the direction of the pressure applicator until the web returns to proper alignment and the pressure applicator is deactuated. The pressure applicator is preferably a device that is brought into contact with the web and applies frictional forces thereon to cause movement of the web along the roll, while avoiding any substantial frictional forces axially with respect to the normal web path. Structure is also disclosed to uncurl rolled selvages of a moving web.

Abstract: Method and apparatus for the high speed, multicolor dyeing of yarns to obtain uniformly dyed lengths of different color along the length of the yarns, wherein a moving strand is collected in a plurality of layers on the surface of a winding drum while a plurality of streams of dye of different color are continuously applied in metered amounts onto the outer surface of the yarn on the drum to form radial bands of color in the collected yarn. The drum is rotated at high speed to cause radial outward flow of dye from inner yarn windings into the outer yarn windings on the drum, thereby providing uniform penetration and coloration of the yarn by the dyes. Dye centrifugally expelled from the outer surface of the yarn is collected and removed by an outer housing peripherally surrounding the drum. The traverse speed of the yarn traverse mechanism of the drum is independently variable to permit the dyeing of yarn sections of selectively variable lengths.

Abstract: A recloseable, dispensing container is disclosed herein. The container, preferably a blow molded container, has at least one side wall with a nestable dispensing spout secured thereto. Most preferably a wall, top and spout are integral having been blow molded with a bottom being provided by way of a metal cap or the like during the filling operation. Initially the pouring spout is nested within the container and is extractable to a dispensing position. A cover is secured to the top pouring spout and is removable therefrom to permit dispensing. The cover is adapted so as to be replaceable after removal, over the pouring spout to reclose and reseal same. The cover is provided with means internally thereof which mate with the spout or a portion thereof to reseal the spout after the cover has been removed.

Abstract: Method and apparatus for the surface coating and impregnation of the interstices of a moving porous web, and particularly method and apparatus for the production of elastomer-coated, bias-cut woven fabrics during a tentering operation. The coating apparatus disclosed consists of means for applying a layer of coating material sequentially to the lower and upper surfaces of the moving web to substantially penetrate the coating into the interstices of the web, while smoothing the surfaces to provide a uniform and controlled coating of desired thickness on the fabric.

The carrier is generally a tubular cylinder and has at least one yarn receiving area thereon with an adjacent surface across which yarn will freely pass when yarn is received therein and the carrier is moved out of the yarn path. In a preferred arrangement, at least one yarn receiving slot is provided in one or both ends of the tube with a post along the outside of the slot across which the yarn may freely pass. Adjacent the bottom of the preferred yarn receiving slot, a groove that extends circumferentially around the cylinder is preferably provided to receive yarn therein for a transfer tail.

Abstract: A solar-heated building structure comprising an exterior shell including a generally semi-spherical roof section comprising a plurality of light-transmitting panes of material providing a air and water-tight exterior surface therefor, horizontal floor means dividing the shell into a heat-insulated living compartment, and an attic compartment extending between the living compartment and the roof section to form a solar heat collector. Air in the attic compartment is heated by absorbed energy from sunlight passing through the light-transmitting panes of the roof section. Means are provided for circulating air into and out of the attic compartment to heat the same, and for circulating the thus heated air through the living compartment to maintain the living compartment at a desired temperature. Means are also provided in the shell for storing heat energy from the heated air for use to heat the living compartment when sunlight energy is unavailable.

The spindle according to the invention contains sound-reducing means which allow free access to the various components of the spindle, which means are formed by an enveloping insulating plate which partly surrounds the spindle assembly, and an insulating ring or cylinder surrounding the twist tube in its part equipped with the twist locking means.The invention applies primarily to high-speed false twist spindles in which the twist is imparted by means of a twist tube equipped with twist locking means.

Abstract: Warp knit denim fabrics wherein differentially colored or colorable yarn sets or groups are knit together in a fabric having a dominant, typically darker, color forming a background wherein flecks of a less dominant, typically lighter, color are present substantially uniformly throughout the surface of the fabric, thereby giving a fabric whose visual appearance is similar to woven denim fabrics, but which possesses superior fabric qualities. After knitting, the differentially colorable yarn sets may be dyed to selectively color one or more of the yarn sets. The denim effect may be enhanced by sanding or napping the denim surface of the fabric to abrade and/or break the dominant color yarns and blend the lighter color therewith. The fabric may be thereafter calendered, and finished in conventional manner.
