    摘要: A reel mounted at the midpoint of a telescoping mast for antennas. The reel winds a multi-celled ribbon cable in two directions at once. The cable passes through the hub of the reel to feed in both winding directions. The reel is mounted on the mast with a clamp that fits a range of existing mast sizes, and distributes the stress of the reel on the mast sufficiently to avoid distortion of the mast. The reel preferably has a cable tensioner wheel on both cable feeds to prevent the cable from slipping off the reel. A selection of cables can be pulled through the multi-celled ribbon sheath by an installer to support a given installation. The outer plate of the reel can be easily removed to remove the cable sheath from the hub for changing the selection of cables in the sheath.

    摘要: A portable sawmill system comprising at least three wheeled, independently movable modules is disclosed. The modules are independently maneuverable to a land site having a ready source of logs to be processed and are arranged in a preselected geometrical configuration adjacent one another and the source of logs. A log from the source is received on the first module and debarked. The debarked log is moved axially and transversely off the first module and onto a second module. A plurality of saw means are carried by the second module to form boards from a log being processed. A third module is located at the output side of the second module and is adapted to receive and further process the boards formed on the second module.

    摘要: A method and apparatus for carrying wires along a vehicle-mounted extensible mast. Said apparatus comprises a telescopically extensible mast and a wire carrier box mounted to a vehicle, a masthead platform mounted to an extreme of the mast opposite the vehicle, a bend-reversible wire carrier, and guides attached to the mast. The bend-reversible wire carrier is threaded through the guides. One extreme of the bend-reversible wire carrier is attached to the vehicle, and the opposite extreme is attached to the masthead platform. The bend-reversible wire carrier comprises clockwise bends alternating with counterclockwise bends separated by bend-reversible wire carrier sections. The bend-reversible wire carrier sections, clockwise bends, and counterclockwise bends are sized to fit into the wire carrier box when the mast is retracted. The method includes the steps of sizing the bend-reversible wire carrier sections, clockwise bends, and counterclockwise bends to fit into the wire carrier box, laying wire into the bend-reversible wire carrier, attaching one end of the bend-reversible wire carrier to the vehicle, threading the bend-reversible wire carrier through the guides, and attaching an end of the bend-reversible wire carrier opposite the vehicle to the masthead platform. A heating means and bend-reversible wire carrier cover are also disclosed.
