Abstract: Method and apparatus to produce a continuous filament textured yarn with unusually low crimp contraction and intermittent crimp and molecular orientation along its length. This is accomplished by the use of an electromagnetic tension device to control the draw in the yarn being supplied to a false twist device driven at a speed to provide low false twist in the yarn being twisted. The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides as it passes to a yarn consuming machine.

Abstract: A fluid sensing apparatus to measure the flow rate of a non-Newtonian fluid by sensing the fluid pressure of the fluid to generate a signal to control a valve.

Abstract: Apparatus for imparting visual surface effects to a relatively moving substrate by application of discrete streams of heated pressurized fluid to surface areas of the substrate. The apparatus includes an elongate manifold assembly comprising two fluid receiving compartments, each extending across the path of said substrate. Fluid from the first compartment passes into the second compartment, which is comprised of a series of chambers, each associated with a throttling gap. The fluid is uniformly mixed within this second compartment, and may then be directed onto the substrate as a thin, continuous stream extending the length of the manifold. By use of blocking streams of relatively cool fluid, smaller streams or groups of streams extending along selected portions of the manifold may be formed.

Abstract: A process is provided for mechanically surface-finishing a textile fabric which comprises continuously feeding said fabric from a source of supply, such that said fabric lies in a single plane, subjecting successive adjacent sections of the fabric to intermittent mechanical impact with an abrasive means across the width of said fabric thereby avoiding substantial sustained contact between the fabric and the abrasive means, the mechanical impact being at a force and frequency sufficient to cause a substantially uniform modification of the surface characteristics of the fabric. Textile fabrics with modified surface which may be made by the above process are also provided. Apparatus for mechanically surface-finishing a textile fabric according to the aforedescribed process is further provided.

Abstract: Method to produce spun-like yarn and product produced thereby by combining a core yarn and an effect yarn in an air jet. The removal speed of the combined yarn from the air jet is intermediate of the speeds of the draw rolls to produce a composite yarn having crunodal loops in one of the combined yarns.

Abstract: A low flow, constant rate pump is provided which comprises a fixed volume container, the inner walls of said container defining a receptacle for a liquid to be dispensed, said container being provided with means to form an unobstructed opening through which said liquid may be caused to flow continuously at a low-flow, constant rate, a propellant chamber within said container formed of a material which is permeable to vapor from a propellant of the liquid-vapor type, a supply of propellant of the liquid-vapor type confined within said chamber, said propellant initially being under pressure sufficient to maintain a major portion thereof in liquid form at normal temperatures.

Abstract: An electromagnetic disc type tension control in which a spring-like member is located between the electromagnetic coil and the lower tension disc to urge the lower tension disc upward towards the upper tension disc when the electromagnet is being supplied low voltage in order to encourage rotation of the tension discs to enhance the removal of finish and foreign material accumulated therebetween.

Abstract: An olefinic polymer composition is provided which comprises an olefinic polymer selected from homopolymers and copolymers made from aliphatic, ethylenically unsaturated monomers containing from 2 to about 10 carbon atoms; from about 100 to about 3,000 parts per million based on the weight of the total composition of a hindered phenolic stabilizer; and from about 100 to about 10,000 ppm based on the weight of the composition of a stabilizer selected from compounds of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each independently selected from an alkyl group containing from 1 to about 20 carbon atoms or alternatively R.sub.1 and R.sub.2 may together with the oxygen atoms to which they are joined form a heterocyclic ring containing two oxygen atoms.

Abstract: An electromagnetic disc type tension control in which the yarn guiding post is slotted off-center between the discs so that the yarn being tensioned is received between the discs and exerts a torsional force on the tension discs to cause the tension discs to rotate in order to enhance the dissipation and self-cleaning of the yarn finish accummulated therebetween.

The tubes are connected to a hollow yarn tube and are located therein to blow the heated air therefrom onto a yarn passing through the hollow tube.

Abstract: A napped fabric is treated to bond the nap fibers together while leaving the nap structure largely open and porous. The surface of the bonded nap is then subjected to a series of spaced short cuts to form spaced clumps of bonded fibers which clumps have free ends projecting from the bonded nap so that they can be brushed from stable upright positions to bent-over positions, giving an attractive rough appearance resembling a split suede leather.

Abstract: The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides to a yarn consuming machine. The balloon control basically employs a bar member under which the yarn passes as it is delivered to a yarn guide tube. The bar member prevents the yarn from rotating as it is taken off over-end from the yarn package thereby alleviating the possibility of yarn entanglement at the yarn tube.
