Abstract: A fly shuttle loom shuttle box is provided with a solid elastomer binder attached at both ends in place of a conventional pivoted, rigid-backed binder. In one modification there is attached to the end of the binder a pivoted extension which permits use of dagger fingers in the normal position on a loom. The greater force exerted by the binder results in improved shuttle deceleration when it enters the shuttle box. This also eliminates picker stick over throw when accelerating the shuttle, which permits, when in proper adjustment, in some cases elimination of picker stick loom side bumper and check strap without, of course, eliminating their useful functions. As there is a considerable amount of heat developed by the flexing of the solid elastomer, it is desirable to provide for ventilation in the form of a few relatively large holes in the elastomer near its center and adjacent to the leather face of the binder.

Abstract: Apparatus is disclosed for treating textile desizing effluent so as to provide effective pollution abatement, and to render feasible the recovery of sizing material from the effluent for reuse as well as the conditioning of the effluent so that it may be recycled for desizing purposes.

Abstract: A drive for a guide bar on a Raschel knitting machine to permit shogging across the full width of narrow fabrics. The drive is by cam, double lever linkage with adjustment slots and pins at at least two points on the levers. For maximum fabric width, for example significantly wider than 1.25 inches, there is also a minor modification of the guide bar supports themselves. These involve pins, and the pins are enough longer so that the bar can move a greater distance without interfering or striking other portions of the knitting machine.

Abstract: A cloth stuffing chamber or container, preferably a tube with entrance and exit portions, is provided with means for preventing backward movement of the cloth. This means is preferably in the form of a fixed ring at the beginning of the exit portion having around its inner surface at least several segments of wire which are slanted toward the exit portion of the tube. There is provided between the entrance and fixed ring a movable ring with wires or pins also slanting in the same exit direction, which ring is reciprocated by a drive, such as a cam and follower. Cloth is introduced into the entrance portion of the chamber and passes through the two rings, and as the movable ring reciprocates, its slanted wires move the cloth forward on the forward stroke and on the reverse stroke the slanted pins of the fixed ring prevent the cloth from moving backwards.

Abstract: A knitted structure and method of making same which includes simultaneously knitting two concentric tubes and interconnecting the tubes by knitting to produce seams which define a garment of juxtaposed portions of the two tubes. Each concentric tube includes a plurality of feeds per course knitted separately on the dial and cylinder needles, respectively, of a circular knitting machine.

Abstract: Yarn is treated in an air entangling apparatus having a yarn introducing guide tube through which one or more yarns are fed, a central bore positioned so that the yarn guiding tube enters it at an angle, and an air jet blowing into the central bore substantially at right angles to the axis thereof. The central bore extends through the texturizing block, and the air jet causes air to leave at both ends of the bore. The yarn continues through the bore, leaving at the downstream end. Overfeed of the yarn is kept at a fairly low point, from a fraction of a percent to a maximum of about 10% and the air pressure is also moderately low, preferably from about 6 psig to 12 psig. At least one of the yarns used is a multifilament yarn and treatment with the present apparatus entangles or interlaces the filaments. If two or more yarns are employed, the product is a plied yarn.

Abstract: The present invention is an automatic bobbin changer for sewing machines of the lock stitch type having bobbin holders with holder pins and latches. A magazine of full bobbins and cases is positioned adjacent the sewing machine, and a cross slide is provided which is movable from a first position to a second. This slide is provided with two powerful magnets, preferably permanent magnets, which are spaced on the slide so that in one position one magnet is aligned with the sewing machine bobbin holder and the second is aligned with the full bobbin magazine. The two magnets are provided with actuators, preferably fluid operated actuators, which can move the magnets forward so that they contact, respectively, an empty casing in the sewing machine bobbin holder and a full bobbin and casing in the magazine. The two magnets then retract toward the slide and the slide moves to the second position.

Abstract: Yarn is treated in an air entangling apparatus having a yarn passageway through which one or more multifilament yarns are fed and an air inlet duct intercepting the bottom of said passageway at right angles, the longitudinal axis of the inlet duct passing through or close to the longitudinal axis of the yarn passageway. A jet of air is introduced into said passageway and strikes the upper wall thereof forming a plural vortex turbulent zone in the upper portion of the yarn passageway which entangles the multifilament yarns. An air outlet duct intercepts the top of the yarn passageway and serves to create an air flow which holds the yarn in the upper portion of the passageway. Yarn is fed into the passageway with a small degree of overfeed, generally from about 0.1 to 10%. A structure, such as a rod, extends into the yarn passageway and contacts the yarn fed therethrough. The resistance to yarn movement resulting from this contact creates yarn slack in the area of the turbulent zone.

Abstract: A device for dispensing and applying stickers by intermittently engaging and advancing a continuous strip carrying said stickers along a path having an abrupt change of direction which causes the stickers to separate from the strip. A mobile clamp intermittently engages the strip and travels a reciprocal path for incrementally advancing the continuous strip to dispense a sticker.

Abstract: A multilayer floor covering is provided which is suitable for use as a playing surface of an athletic facility. The floor covering comprises a composite needlepunched material in which a fiber batt bottom layer is needled into a support layer so that a portion of the fiber batt protrudes through the top of the support layer, a layer of polyurethane elastomer adhered to the composite needlepunched material and a top wear coating of polyurethane adhered to the layer of urethane elastomer.

Abstract: A high temperature resistant filtration material is produced having outer layers of a nonwoven fabric made of fibers of an aromatic polyamide having repeating units of the formula ##SPC1##A first inner layer of nonwoven fabric made of glass fibers and a second inner layer woven from yarns of glass or said aromatic polyamide. The fibers of the layers are interentangled by needling to form an integral structure.
