Abstract: A metal connector (10) for the end portion of a plastic tension rod (12) having a continuous wedge-shaped internal helical groove (18) adapted to be filled with bonding material (21) bonded to the rod (12) and non-adherent to the metal surface of the groove (18).

Abstract: Disclosed is a novel combination of a sewing machine needle having a rectangular eye and a monofilament sewing thread of a synthetic material having a width to thickness ratio of approximately 3.0:1 to about 4.0:1.

Abstract: The present invention relates to FRP members, the apparatus and process for making same. The FRP members are reinforced with helical strands of reinforcing material disposed in expanded helices of opposite hand, the helices of each hand being contained in discrete layers. The lead angle of each helix may be constant or varied along the length of the member independently of whether the member is cylindrical or tapered in order to provide the desired structural characteristics. The process comprises impregnating the reinforcing strands with resin and wrapping those strands onto a mandrel by apparatus in which relative rotational as well as relative translatory movement between the mandrel and a winding head may be effected to wrap the strands onto the mandrel. At least one relative movement may be selectively varied to effect the desired lead angle to the helically disposed reinforcing strands along the length of the mandrel.

Abstract: The hook assembly includes a hook which passes through a hollow top rung of the ladder and an enclosed locking assembly which secures the hook to the rung for selective rotation between a storage condition and a hooking use condition.

Abstract: Disclosed is a spooling apparatus that can be threaded on the fly to anchor, controllably twist and wind filament onto a receiving spool. A receiving spool is non-rotatably mounted on a spool shaft for axial reciprocation. A lead-in pulley, whose rotational axis is perpendicular to the receiving spool axis, is spaced axially outboard with respect to the receiving spool. A flier is mounted to rotate concentrically about the receiving spool and presents a pick-up head adapted to engage the feed run of the filament as it passes between the lead-in pulley and an orienting pulley located in proximity to the inboard end of the receiving spool. The orienting pulley is canted such that the tailing run of the filament cannot be engaged by the pick-up head as it rotates with the flier although the canting of the orienting pulley disposes the feed run such that it will be engaged by the rotating pick-up head when the spool reaches a predetermined position along its range of axial reciprocation.
