Abstract: A grain cart has a wheel supported frame on which is mounted an open top container having inclined bottom walls and including a single discharge auger conveyor having a lower section extending from a sump for the container adjacent a front left inclined corner portion of the container. The auger conveyor has an extended upper section supported by a hinge assembly having a pivot axis offset and askewed at an acute angle from the auger axis. The hinge assembly provides for pivoting the upper conveyor section between an inclined grain discharge position projecting upwardly, laterally outwardly and forwardly from the container and a stored position inclined downwardly at a substantial angle from the hinge assembly in front of the container. In the stored position, the grain discharge outlet is located lower than the top surfaces of the wheels.

Abstract: A wheel supported grain wagon includes a container with sloping side walls extending to an incline bottom wall, and a gravity discharge opening is formed within one of the side walls adjacent the bottom wall. A door panel is supported by tracks for movement between an upper open position and a lower close position covering the opening. A grain discharge chute extends from the opening and has opposite side walls connected by a bottom wall. The chute is adjustably supported by a pair of horizontally aligned pivot pins projecting into corresponding slots within a pair of side support brackets secured to the container. The slots extend generally perpendicular to the side wall and have longitudinally spaced bottom notches which selectively receive the pivot pins in response to manually lifting and shifting the discharge chute for selectively positioning the outer edge of the discharge chute at different elevations.

Abstract: A grain wagon includes a wheel supported frame supporting a container having inclined front and rear walls connected by opposite inclined side walls. Each side wall has inwardly projecting wall portions defining a wheel well for receiving longitudinally offset dual wheels or extra wide wheels. The rear wall includes a portion sloping between the wheel well wall portions to a forward grain removal zone, and generally triangular diverter walls extend from the rear wall to the wheel well wall portions. A corner discharge auger conveyor extends from the grain removal zone and has an upper portion which pivots to a stored position adjacent the front wall of the container. The dual wheels are positioned within the wheel wells by support members having end portions pivotally connected to the wagon frame and opposite end portions connected to the frame by laterally slidable clamping plates.

Abstract: An environmental protection and detection system includes a vapor and gas impervious barrier extending beneath at least part of the area of an enclosure to prevent fluids leaked or spilled within the enclosure for flowing downwardly into the underlying soil and ground water and to prevent vapors and gases emanating from sources beneath the enclosure from percolating upwardly into the enclosure. Lengths of perforated pipe are positioned above the barrier and are connected to points outside the enclosure for use in detecting and removing contaminants leaked or spilled within the enclosure. Lengths of perforated pipe are positioned beneath the barrier and are vented to the atmosphere for preventing accumulations of fluids emanating from sources beneath the enclosure.

Abstract: A grain wagon includes a wheel supported frame on which is mounted a hopper or container for receiving grain, and the wagon is pulled by a tow vehicle or tractor. An inclined discharge auger conveyor has an outer section which folds between a stored position and an operating position projecting upwardly and forwardly and laterally outwardly from the container. The outer auger section has a pivotal discharge spout with a pivotal internal baffle, and the spout is actuated by a double acting hydraulic cylinder controllable through hydraulic lines from the cab of the tractor so that the tractor operator may fully load and “top off” the grain within an adjacent semi-trailer as the tractor operator pulls the wagon along the side of the semi-trailer. In one embodiment, the outer section of the auger conveyor has an outer telescopic housing extension which carries the discharge spout and extends and retracts automatically with folding of the outer auger conveyor section.

Abstract: An orientation maintained fastener delivery system (10) includes an escapement (14), a transfer system (16), and an injector (18). The escapement (14) regulates the flow of fasteners (20) through the orientation maintained fastener delivery system (10). The escapement (14) also delivers fasteners (20) in a desired orientation to the transfer system (16). The transfer system (16) includes a plurality of tubes (26,30) and a distributor (28). The tubes (26,30) maintain the desired orientation of the fasteners (20) as the fasteners (20) are transported to the injector (18). The distributor (28) aligns a tube (26) coupled to the escapement (14) with a tube (30) coupled to the injector (18). The injector (18) receives fasteners (20) from the transfer system (16) in the desired orientation and delivers the fasteners (20) in the desired orientation to an installation device (22).

Abstract: In a fuel bundle for a boiling water nuclear reactor, modification of the spacers at the peripheral spacer band is made to maintain a more uniform spacing of the peripheral fuel rods from the channel walls to avoid critical power limitations. The conventional fuel bundle construction include a plurality of side-by-side sealed vertically disposed nuclear fuel rods in a square array supported at a lower tie plate, at least some of the fuel rods fastened to an upper tie plate, and held in designed spaced apart relation as a unitary mass by intermittent vertically placed spacers. A square sectioned channel surrounds the upper tie plate, the lower tie plate, and the fuel rods and spacers therebetween. The square sectioned channel functions to confined fluid flow interior of the fuel bundle between the tie plates and through the fuel rods. At the same time, the channel separates a core bypass region exterior of the channel having high moderator density from the flow path interior of the fuel bundle.

Abstract: A masked ion beam lithography (MIBL) system and method is disclosed which is considerably more compact and economical than prior ion implantation devices. An H.sup.+ ion beam is extracted from a source in the form of an angularly expanding beam, and is transmitted through two lenses that sequentially accelerate the ions to energies in the range of 200-300 keV. The first lens focuses the beam so that it emerges from a crossover point with an amplified angular divergence at least three times the divergence of the initial beam, thereby considerably reducing the necessary column length. The second lens collimates the beam so that it can be directed onto a mask to expose resist on an underlying semiconductor substrate. A series of extraction electrodes are used to provide an initial point source beam with a desired angular expansion, and a specially designed sector magnet is positioned between the extraction mechanism and the first lens to remove particles heavier than H.sup.+ from the beam.

Abstract: A self-contained passive solar heating system includes first and second heat pipes, each having a refrigerant medium therein, a condenser portion and an evaporator portion, with the condenser portion of the first heat pipe being coupled to the evaporator portion of the second heat pipe for transferring heat thereto when the pressure within the first heat pipe is greater than the pressure within the second heat pipe. The evaporator portion of the first heat pipe is adapted to be exposed to a source of heat and the condenser portion of the second heat pipe contacts a medium to be heated. A temperature control mechanism may be installed as the coupling between the first and second heat pipes for uncoupling the same when the temperature within the first heat pipe falls below a predetermined temperature.
