Abstract: A hook assembly that assists a person in engaging the handle of a pull cord from a gasoline engine. The hook assembly engages the handle with a hooked plate. The hooked plate has a curved section that forms a catch trough that directly engages and holds the handle of the pull cord. A cord slot is disposed within the curved section of the hooked plate. The cord slot extends into the catch trough. This divides the hooked plate into two curved fingers on either side of the cord slot. A wrist band is wrapped around the wrist of a user. The hooked plate is joined to the wrist band with a pivoting connection. The pivoting connection enables the hooked plate to be selectively positioned between a deployed position and a stored configuration.

Abstract: A method of inserting a fill yarn on an air jet loom includes propelling a fill yarn with one or more air jets from the insertion side to the exit side of the loom, where the yarn comprises a strand of individual filaments, the strand having a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape, and where the flat spots provide increased drag for propulsion by the air jets.

Abstract: A self supporting, helically wound package of yarn suitable for being payed out by withdrawing the yarn without collapse of the package is disclosed. The yarn comprises a strand of individual filaments, the strand having a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape. The package has edge portions positioned axially at the ends of the package, and the flat spots are positioned in the edge portions of the package.

Abstract: A woven fabric of warp yarn and fill yarn uses a strand of individual filaments for the fill yarn, where the strand has a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape, where the effect of the flat spots is differentiated fill yarn in the woven fabric.

Abstract: A method for improving the adhesiveness between a polyolefin resin and a sized glass fiber which comprises forming a mixture of the resin, a fiber and an organic acid and molding the mixture.

Abstract: A non-discoloring glass strand size comprises a thermoplastic polyurethane emulsion produced by the chain extension of an NCO-terminated prepolymer, which prepolymer is prepared by the reaction of an aliphatic or cycloaliphatic diisocyanate with a polyalkylene ether polyol and is particularly suitable for glass incorporated in polyamide resins.

Abstract: Glass fibers are coated with a mixture of an organo silane coupling agent, an oxidized polyolefin, and a carboxylated high molecular weight elastomer having a solubility parameter similar to that of polyolefin. In the preferred arrangement the coupling agent, polyolefin, and high molecular weight elastomer are in the form of an aqueous emulsion which is applied to the fibers as a coating at forming, and then dried. The silane coupling agent may be applied either as an initial coating or in mixture with the emulsions, and the coated fibers when dried are particularly adapted for the production of composites having a polyolefin matrix and a reinforcement of the coated glass fibers.
