    摘要： A grass collector for receiving clippings discharged from a port at the rear of a mower housing. The collector is secured to a frame member which is pivotally connected to support members joined to the mower so as to be able to swing between a closed, clippings-receiving position adjacent the rear discharge port and an open, displaced position at which clippings can be dumped from the collector. The position of the collector is selectively controlled by the operator of the mower, and a spring arrangement is provided for retaining the collector in the selected position until over-ridden by the operator.

    摘要： A hybrid air vehicle is disclosed in which a cover is provided for a plurality of air cushioned landing pads to reduce drag when airborne. The pad is inflatable to provide an air cushioned during touchdown and deflatable during flight of the air vehicle. The cover can include a first cover portion and a second cover portion. A first cover roller of the first cover portion and a matching second cover roller of the second cover portion abut to cover the corresponding pad. The first cover roller and the second cover roller, which are separate and free from a physical linkage there between, are separable in an eyelid fashion to expose the corresponding pad. A separation gap between the first cover roller and the second cover roller is increased or decreased by roller straps to cover or expose the corresponding pad.

    摘要： A plasma jet system includes a housing with an opening. A plasma generator is coupled to ionize a fluid in the housing. An electromagnetic accelerator is coupled to generate an electric field that accelerates ionized fluid in the housing toward the opening. A controller can modulate the frequency of the electric field to cause the ionized fluid to form a plasma vortex flow through the opening. A magnetic field is applied normal to the direction of the plasma vortex flow to mitigate the momentum of the electrons. The electrons slowed by the magnetic field can be collected and conducted to a location where they are re-inserted into the plasma vortex flow to maintain charge neutrality.

    摘要： An apparatus for transporting racks of sealed sample tubes, mixing a sample material contained within the tubes, and aspirating samples from the tubes. The apparatus includes a car which runs along a rail. The car drives racks containing the sample tubes into a mixer channel disposed above and running parallel to the rail. The mixer channel is mounted to rotate about an axis parallel to the rail to mix samples and position the tubes to be aspirated. A push pin mounted adjacent to the mixer channel extends into the mixer channel and urges individual tubes against an aspirator assembly mounted on the opposite side of the mixer channel. An input queue is disposed proximate the input side of the rail and an output queue disposed proximate the output side of rail. The input queue supports the racks and feeds them into position to be driven by the car mechanism into the mixer channel. The output queue receives racks after being aspirated and feeds them aft to make room for subsequent racks driven by the car from the mixer channel. The racks include a lateral front wall, a lateral rear wall and a horizontal bottom wall connecting the front wall to the back wall. The racks also include a plurality of vertical side walls connected to the front wall and the back wall to define a plurality of tube receptacles. The bottom wall includes a plurality of equidistantly spaced apertures, each of which is centrally located within a tube receptacle to provide the push pin access to the tubes. The bottom wall also includes a plurality of ribs extending from the front wall to the back wall to be engaged by the car. Biasing means are disposed within each of the tube receptacles to support sample tubes therein.

    摘要： A half-nut block containing a threaded bore and a larger, overlapping, unthreaded bore is engaged with a lead screw. The larger bore overlaps the threaded bore so that effectively a half-nut results. The half-nut comprises a face having an acute angle in relation to the lead screw and this angled face contacts the inside of a bearing block within which the half-nut is mounted. The bearing block is slidably mounted on a C-tube which is mounted around and extends along a predetermined length of the lead screw. Also mounted on the C-tube is an arm for transmitting the linear motion of the bearing block to a remote point such as the plunger of a syringe. The arm is coupled to the bearing block at points selected so that transmission to the arm of any wobbling of the bearing block is reduced. The arm includes a lever which engages a cam formed on the half-nut to force the half nut to disengage from the lead screw when the arm is to be moved to a new location on the lead screw. A spring bias is coupled to the half-nut block opposite the cam for urging the half-nut block back into contact with the lead screw after disengagement. A stop mechanism prevents undesired disengagement of the half-nut block from the lead screw when force is applied other than by the cam block.

    摘要： An air vehicle includes a bag skirt extendable along a portion of a hull of the air vehicle. The bag skirt is inflatable to provide an air cushion during touchdown and deflatable during flight of the air vehicle. The air vehicle also includes a cover roller adjacent the bag skirt, and a cover portion coupled to the cover roller. The cover roller is operable between exposed position and unexposed positions to expose and hide the bag skirt with the cover portion. The cover roller includes an extensible shaft and a pad securely wrapped around the extensible shaft. The extensible shaft is capable of being rotated along a shaft axis. One end of the extensible shaft is pivotally coupled to the hull by an anchor. A circumference of the cover roller is configured as a function of a distance between the exposed and the unexposed positions.
