Abstract: A tool provides a means for easily and safely removing a timepiece mainspring from its barrel for cleaning and lubricating. A barrel holder is provided having a rim, and an essentially planar surface which includes openings therethrough. A mainspring barrel containing a mainspring is inserted into a mating opening. A barrel holder cap is snapped over a rim of the barrel holder. The cap surface includes openings opposite the barrel holder openings. The cap and barrel holder thereby form a receptacle for receiving an extracted mainspring. The watchmaker accesses a loop of the mainspring in the barrel holder, and removes the mainspring. The energy in the spring is thereby released and the expanding spring is captivated in the receptacle, permitting removal therefrom for cleaning and lubricating.

Abstract: A necklace formed of a plurality of interconnected globular like beads wherein the beads are adapted to permit installation of gemstones in selected beads, and for adding gemstones at later times. A central pendant includes a central bead having a pair of beads, each of which are permanently attached thereto at about a 45 degree angle with respect to a vertical center line of the central bead. A pair of strings of single beads is formed with one of each attached to the pendant. The single beads are movably linked to form two strings thereof having clasp for forming a necklace. Each of the pendant beads and the string beads are globular in shape, and include a partial rear central bore therein. At any time, a bead can easily be modified to form a gemstone setting in the front face thereof, and a stone installed therein. Thus, the necklace of the invention can provide a means for celebrating anniversaries and other special occasions.

Abstract: A system and method for extracting used transmission fluid from an automatic transmission in a motor vehicle utilizing the vehicle engine. A reservoir is provided having a free floating piston therein, dividing the reservoir into two chambers. A first flexible line connects from a first chamber to a transmission fluid outlet of the transmission, and a second flexible line connects from a second chamber to a fluid input of a transmission fluid cooler. The second chamber is initially filled with fresh fluid forcing the piston toward the first chamber. Operation of the vehicle engine causes the transmission pump to pump used fluid into the first chamber, forcing the piston to expell fresh fluid from the second chamber, and into the cooler and transmission. A sight gauge in the first flexible line permits visual monitoring of the flow of dark, used fluid to determine when all of the fluid in the transmission has been ejected, collected in the first chamber for disposal, and completely replaced with fresh fluid.

Abstract: A module formed by an array of pipes is provided for installation in front of existing radar and sonar transducers. A preferred array is formed by a section of honeycomb material in which each pipe has a hexagonal cross section and is mounted in an insulating sheath. Each pipe acts as a radiator of energy from a transducer that combine in phase to produce a beam narrower than the beam from the transducer. The module is effective to improve the range and resolution of forward-looking radar and sonar devices.

Abstract: A pipe handler for safely handling large pipes utilized in gas and oil lines, and the like utilizes a horizontal spreader bar having a dependent lifting arm hingedly attached at each end thereof. Each of the distal ends of the lifting arms includes a pivoted lifting shoe. The spreader bar is to be suspended from a crane. A winch having a double drum is mounted to the spreader bar and powered by an electric motor. Each drum includes a cable operatively connected to a respective one of the lifting arms. Initial operation of the winch causes the arms to swing outwardly. To handle a large pipe, the crane operator positions the spreader bar over a pipe to be moved, and operates the winch to swing the lifting arms outwardly sufficiently to allow the lifting shoes to thereafter swing inwardly to insert the lifting shoes into the respective ends of the pipe. The pipe can then be hoisted and moved to a desired point.

Abstract: A hinged safety hasp has a hasp plate, a hasp leaf, a staple plate, and a magnet plate. The staple plate and the magnet plate are hingedly attached to the hasp leaf and are to be attached by screws to a surface in an opposing configuration by. The magnet plate includes a flat magnet on its surface. When the hasp is open, the hasp leaf is folded back to contact the magnet, thereby maintaining the hasp plate in a safe position to prevent possible injury to a person contacting an extending hasp leaf.

Abstract: A fishing float includes a buoyant body having a central opening therethrough and a longitudinal body slot in an outer surface of the body. A rod through the opening includes a disk at each end thereof, each disk having curved slots. A fishing line is inserted in the body slot and the disk slots, and the rod rotated with respect to the body to thereby captivate the line between the disks and the outer surface of the body.

Abstract: A trailer for towing by an automotive type vehicle includes a single longitudinal beam. A plurality of adjustable transverse cradle support members are mounted along the beam. A single castered wheel is mounted near the back end of the beam. A hitch for attachment to a towing vehicle at the front end of the beam maintains the beam aligned with a longitudinal axis of the towing vehicle. Various types of loads may be accommodated by attaching appropriate type cradles to the cradle support members, and the spacing of support members may be adjusted to accept the load.

Abstract: A window washing tool includes a sponge-like applicator for applying water and cleaning fluid to a window and a resilient squeegee blade in a head portion of the tool. An elongate handle is attached to the head. A rear bar of a pair of hinged blade wiping bars is hingedly attached to the head portion to be moved from a rear retracted position to a forward position. A flexible tube is attached to a front wiping bar and extends along the handle. A knob at a distal end of the tube is operable to move the wiping bars from the rear retracted position to the forward position in which the wiping bars clamp on the edge of the squeegee bar, and to return the wiping bars to the retracted position, thereby absorbing and expressing cleaning fluid to provide a relatively dry squeegee blade for subsequent use.
