Abstract: A key switch assembly for a saddle riding vehicle includes a cover structure adapted to cover a portion of a frame arranged between a handlebar and a seat in a lengthwise direction of the vehicle. A cap structure is removably engaged to the cover structure and includes a first structure disposed inside a cavity of the cover structure and defines an opening, and a second structure extending vertically from the first structure and adapted to be removably coupled to the frame. The second structure is adapted to be arranged underneath the cover structure. A key switch is coupled to the first structure and extends through the opening. The key switch is configured to electrically connect and disconnect the at least one electrical storage unit to the at least one traction motor.

Abstract: A vehicular door assembly includes a door and at least one hinge structure. Each of the at least one hinge structure includes a knuckle and a bushing. The knuckle extends away from the door. The door and the knuckle of each of the at least one hinge structure are integrally formed as a unitary structure. The knuckle of each of the at least one hinge structure includes an upper surface and a lower surface, and defines a bore extending through the knuckle and opening onto each of the upper surface and the lower surface. The bushing defines a hinge aperture and a hinge axis. At least a substantial portion of the bushing is positioned within the bore defined by a respective one of the knuckles. Each of the at least one hinge structure is configured for coupling with a frame of a vehicle. Vehicles are also provided.

Abstract: Lightweight and rigid, leaded or lead-free integral radiation shielding structural compositions comprising two or more radiation attenuating elements or compounds thereof, selected for having compatible radiation attenuating characteristics, dispersed in a thermoplastic or thermoset resin. The radiation shielding structural compositions of the present invention can be used to functionally and structurally replace lead-lined structures in medical and industrial x-ray systems. The radiation shielding structural compositions of the present invention can also be formulated to minimize the density of the resulting structure.

Abstract: A high temperature battery which has a cathode comprising either sulphur or a metal sulphide, an anode comprising either an alkali metal, an alkaline earth metal or an alloy of either and, disposed between them, an electrolyte comprising an alkali metal halide. The materials in the cathode composition are electrochemically in excess to the materials in the anode composition. Potassium chloride, potassium iodide or, preferably, potassium bromide is added to the anode, the cathode and the electrolyte. When potassium bromide is added, ideally, it is added to the electrolyte in excess to the alkali metal halides present in the electrolyte. In one particular example, the cathode comprises iron sulphide, the anode comprises a lithium aluminum alloy, the electrolyte comprises a ternary metal halide and potassium bromide is added to all three. Magnesia can be further added to the anode, cathode and electrode.

Abstract: A solids-gas contact vessel, having two vertically disposed distinct reaction zones, includes a dynamic seal passing solids from an upper to a lower zone and maintaining a gas seal against the transfer of the separate treating gases from one zone to the other, and including a stream of sealing fluid at the seal.

Abstract: Particulate oil shale is subjected to a pyrolysis with a hot, non-oxygenous gas in a pyrolysis vessel, with the products of the pyrolysis of the shale contained kerogen being withdrawn as an entrained mist of shale oil droplets in a gas for a separation of the liquid from the gas. Hot retorted shale withdrawn from the pyrolysis vessel is treated in a separate container with an oxygenous gas so as to provide combustion of residual carbon retained on the shale, producing a high temperature gas for the production of some steam and for heating the non-oxygenous gas used in the oil shale retorting process in the first vessel. The net energy recovery includes essentially complete recovery of the organic hydrocarbon material in the oil shale as a liquid shale oil, a high BTU gas, and high temperature steam.

Abstract: A device for impaling and lifting hay bales consisting of a long, round, pencil-pointed shaft for said purpose plus two shorter shafts of similar design protruding just below and to each side of the main impaling spear for the purpose of stabilizing the bale in the process of loading and handling. This structure is mounted on a rigid steel frame which is designed for attachment to any ordinary hydraulically operated front end loader, or for attachment to any common three-point tractor hitch. Optimum utility is achieved with a tractor having such devices mounted at each end for use at the same time.

Abstract: A hay hauler and feeder includes a platform of wood framed in steel with demountable racks which, when in place, serve as self-feeders, on sides, front and rear. Feeding stations are divided with steel bars angled to the right or left to limit and control hay withdrawal in order that the contents may be fed with minimum wastage. The hauler-feeder is mounted on a single axle mounting with four wheels in tandem which are capable of oscillation for maximum uniform weight distribution and a trailer jack at the front tongue for leveling when field-feeding.
