  • Patent number: 4623504
    Abstract: A method of making a tendon suitable for use in the post-tensioning of concrete as well as for other applications is disclosed. The method comprises the steps of coating a wire or a multiple-wire strand with a thin coat of a corrosion inhibitor. In the preferred embodiment, the thin coat may be more easily applied by coating the wire or multiple-wire strand with a thick coating of corrosion inhibitor and then removing the surplus amount of the corrosion inhibitor from the outer periphery of the strand, including the interstices, to leave the desired thin coat. A seamless plastic jacket is then formed around the wire or the multiple-wire strand while simultaneously creating a differential pressure across the wall of the seamless plastic jacket to provide a loosely fitting seamless plastic jacket.

  • Patent number: 4252325
    Abstract: A hunting arrow that causes a continuation of the bleeding in wounded game. The arrow embodies a hollow shaft having a forward end and a rearward end with an arrow mounted at the forward end and a nock mounted at the rear end thereof. A length of high strength line within the hollow shaft is fixedly connected at one end to the rearward end of the shaft and the other end of the line is fixedly connected to the arrowhead so that in the event the hollow shaft is broken the line still interconnects and limits relative movement of the broken parts of the shaft whereby they move along with the arrowhead and the game.
