A swivel device for coupling gangions to longlines and an apparatus for automatically attaching the same. The device includes a cylindrical stop sleeve fixedly attached to the longline, and a detachable swivel body with an aperture therethrough sized for rotatably receiving the sleeve therein. The body has a sidewall opening communicating with the body aperture and sized to allow lateral passage of the longline, but not the sleeve, therethrough. The body has an ear for attachment of the gangion and has depressable stops spaced apart for receiving the sleeve therebetween and restraining axial movement of the body relative to the sleeve while permitting rotational movement thereabout. The stops have axially outward facing cams which depress the stops when engaged by a tool or by a sleeve entering the body aperture. The apparatus has a gravity-feed track for loading a plurality of swivel bodies, and a swing arm having a carrier positioned to receive the bodies from the track and releasably hold the bodies in position, with the longline extending through the body aperture in preparation for receipt of a sleeve therein. The swing arm is movable to a release point in response to the travel of the sleeve with the longline. A retainer allows escapement of individual swivel bodies from the feed track while retaining the remainder of the bodies on the track until the swing arm is in position to receive another body. A stop guide is positioned to limit travel of the bodies fed from the track to the swing arm.

Method or apparatus for unwinding gangions from a longline fishing line by first wrapping all of the gangions in a first direction about the longline and thereafter unwrapping them to leave them relatively free from the longline. Wrapping and unwrapping can be accomplished by running the longline through a series of hollow cylinders having permanent magnets mounted on the interior surface. The cylinders are rotated in opposite directions. As the gangions enter the first of the cylinders, the hooks are attracted to the magnets in the rotating cylinders and are rotated about the longline so as to wind all of the gangions in a common direction. Thereafter, the hooks are attracted to the magnets in the second cylinder, which is rotating in the opposite direction, thereby unwinding the gangions. In this manner, regardless of the original wrap of the gangions about the longline, each can be completely unwrapped and left dangling from the longline.

In a power tool for binding concrete-reinforcing bars together with a wire tie, a predetermined length of wire is fed into a pair of jaws having loop-forming grooves therein. A rotatable inner mandrel carries a cutter bar while an outer mandrel is rotatably mounted on the inner mandrel. Radial flanges on the outer mandrel form openings with the cutter bar for the passage of the wire as it is formed into a loop by the jaws. Relative rotation of the inner mandrel relative to the outer mandrel cuts the wire and then twists the cut ends into a wire tie that binds the reinforcing bar. Controls are provided for properly positioning the openings for the passage of the wire upon each successive cycle of operation.

A plastic heat exchange tube for use in combination with large dry and wet/dry type cooling towers. The tube includes a tubular center portion around which an open ended channel portion spirals over substantially the entire length thereof, with the open end in communication with the interior of the center portion. The optimum channel portion height to pitch ratio is 1.5 to 1. A web portion extends through the center portion of the tube.

A magnetically driven, sealed gear pump has hard metal gears and a pair of relatively soft gear tip seals near the pump inlet chamber that compensate for wear of its parts.
