Title: Lift-liner apparatus and methods relating to lift-liner
Inventor: BEALE ALDON EVANS
IPC: B65D88/22
Filed: 1998-11-12
Granted: 2007-08-07
Abstract: A lift-liner provides efficient transport of units of bulk cargo (e. g., radioactive hazardous material waste), and economical disposal of the lift-liner for storage of the waste therein. The cargo is also transported in the lift-liner, e.g. from a remediation site to a railroad siding. Cargo units are defined by the lift-liner, which may contain up to twelve tons of the waste. A high-load-capacity container of the lift-liner may have five straps connected to two first opposite walls, with four straps connected to two second opposite walls, and with a bottom between corners of the container. The straps may receive up to twelve tons of vertical lifting force from a lift grid having a connector vertically above and aligned with each strap. The straps assist in containing the waste, and apply vertical forces to the walls and to the bottom to lift the container. Embodiments of the lift-liner are provided for waste in the form of contaminated dirt, and for contaminated demolition materials. Methods include steps providing the lift-liner with the container and the straps, and for loading the gondola car efficiently with fewer than ten units (of twelve tons each), minimizing the number of unit loading operations needed to fill the gondola car. Flaps at the top of the container are provided with loops and webs to facilitate defining tucks as the flaps are pulled across the open top of the container, and for tying the flaps securely closed.

Abstract: An improved vehicle road sensor is provided for signalling the passage of a vehicle over a predetermined location on a roadway. The vehicle road sensor includes a membrane switch which includes a first member and a second member. The first member includes a non-conductive substrate, a pair of electrically-conductive stripes upon the non-conductive substrate, an electrically non-conductive gap separating the electrically- conductive stripes, and an electrically-conductive lead connected to each electrically-conductive stripe. The second member includes an electrically-conductive strip which is superposed upon the electrically-conductive stripes on the first member. The second member is normally out of electrical contact with the electrically-conductive stripes on the first member. The second member is sufficiently flexible, so that, under a compressive load, it deflects to shunt across the electrically non-conductive gap, thereby to permit electric current to flow from the electrically-conductive stripes to the second member. Various arrangements of separate, but connected sensitive zones may be provided along the length of the sensor. Vehicle wheels of different widths would activate a different number of active sections, thereby approximating tire widths, for detecting the presence of one tire or two tires.

The upper rope loops located at the extremities of the horizontal line of the tubular T are meant to connect to a dumbbell and contain each one plastic washer to counter friction between the barbell and the rope. Two bracelets located at the upper loops ensure firm hold of the barbell by resizing the loops when needed.

Abstract: The present invention relates to a gas turbine combustor for homogeneous air to flow in by eliminating the turbulences from the air thereby to reduce the combustion instability.      In a combustor 3, there are arranged at the center a pilot nozzle 8 and eight main nozzles 7 around the pilot nozzle 8. The air flows in around the individual nozzles 7 and 8 to the leading end of the combustor 3 so that it is used for the combustion. An annular flow ring 20 having a semicircular section is disposed at the upstream end portion of a combustion cylinder 10, and a punching metal (or porous plate) 50 and a surrounding punching metal rib 51 are disposed downstream of the flow ring 20. The air inflow is smoothly turned at first by the flow ring 20 and is then straightened by the punching metal 50 so that the air flows without any disturbance around the individual nozzles i and 8 to the leading end thereby to reduce the combustion instability.

Abstract: This invention is a reusable electrosurgical return electrode pad (41) for use with electrosurgery. In one embodiment it includes a presentation or working surface area lying in a range of from about 100 square centimeters to about 20,000. In another, the working surface is at least as large as that of a projection of about half of the profile of the trunk of a patient. In yet another, it includes a working surface area at least as large as that of a projection of the profile of both the trunk and legs of a patient. It is adapted for disposition on the working surface of an operating table or dentist's chair immediately underlying a patient during electrosurgery. By presenting a very large working surface area, the need for direct contact or contact through conducting gels is eliminated; through employment of washable surface areas, it is made readily cleanable and reusable; and through the selection of resistance characteristics for the electrode materials of the principal body of the electrode. Through tailoring of electrode geometries, it is made self-limiting as to current density, and temperature rise so as to prevent patient trauma. An optional sleeve (50) is provided for cooperative use with the electrode.

Abstract: High power semiconductor lasers for pumping fiber devices, such as fiber amplifiers and fiber lasers, include an optical gain region disposed between a rear end and the output end, the width of the optical gain region being greater at the output end than at the rear end. The optical gain region may include a single mode channel region coupled to a flared amplifier region. The light output from the laser is coupled via a lens system into a fiber for propagating to the fiber device to be pumped. Light is fedback into the laser, for example from a fiber Bragg grating, to induce the laser to operate in coherence collapse. The broad bandwidth output associated with coherence collapse permits the laser to deliver high optical powers into the fiber without the onset of stimulated Billion scattering. Fiber grating feedback improves the quality of the beam output by the laser, thus enhancing coupling efficiency into the fiber. The pump laser may be used to pump multiple fiber devices.  Multiple pump lasers may be combined together.
