Abstract: A door panel for a refrigerating appliance includes an inner liner. An outer wrapper is attached to the inner liner and defines an insulating structure with an insulating cavity disposed therein. An insulating material is defined within the insulating cavity. A dispenser structure is defined within a central portion of the inner liner and the outer wrapper. The dispenser structure defines an insulated dispenser portion therein. A dispenser conduit extends from an interior area disposed above the dispenser structure to an external dispensing cavity and passing through the insulated dispenser portion.

Abstract: The present invention discloses a precast railway crossing slab adapted to extend transversely across the surface of conventional railway ties, with slots or gaps dimensioned and disposed to receive a pair of railway rails therethrough. The crossing slab includes a post-tensioning system in which metal cable strands or tendons are sheathed within plastic tubes and are positioned in the slab mold frame prior, to pouring of concrete. Tendon anchors are also disposed in the slab mold frame prior to pouring. After the concrete hardens, a hydraulic jack is used to tension and anchor the tendons in a stressed condition, thus providing reinforcement to the slab. The railway crossing slab of the present invention may be utilized with or without surface or edge metal plating. Flange way fillers which typically comprise rubber strips extending between the sidewalls of the metal rail and the concrete slab may optionally be employed.

Abstract: An apparatus is disclosed for covering and protecting the forward surface of the fuel tank mounted to a motor vehicle. The protective device is adapted for a motorcycle framework, which may include a fork assembly in the vicinity of the mounted fuel tank. The apparatus has coverings, which may be flexible material, sized and adapted to cover the exposed areas of the forward surface of the fuel tank. The apparatus comprises several embodiments configured to cover different selected portions of the fuel tank with connecting assemblies to accommodate the motorcycle frame and fork assemblies where the fuel tank is attached. A first connecting assembly spans a portion of the forward surface of the fuel tank and interconnects the first and second cover portions when mounted to the tank. A second connecting assembly extends rearwardly from the covering sections to operatively engage a portion of the motorcycle. Each of the cover portions is generally triangular in shape having two linear sides and an arcuate side.

Abstract: A custom switching circuit board which is installed into a personal computer allowing the user to upgrade his or her computer to a multiple operating system computer. The custom switching circuit board allows switching of a plurality of bootable hard disks, each with the capability of running one operating system. A key switch is provided for switching to each of the system positions and the key is removable in all positions.

Abstract: A process is provided to produce, stabilize, dedust and upgrade synthetic oil, such as shale oil. In the process, synthetic fuels, such as oil shale, tar sands and diatomite are retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of dust. In order to minimize polymerization of the product stream and agglomerate the dust, the product stream is stabilized, upgraded, and pretreated prior to dedusting, in a hydroprocessor, such as an ebullated bed reactor, with a hydroprocessing gas in the presence of a catalyst. The hydroprocessing gas can be hydrogen, scrubbed fractionator gases, or hydrocarbon-enriched hydroprocessor off gases.

Abstract: An electrical cable includes a core, a jacket and improved shielding with unexpectably low transfer impedance. The shielding includes an inner foil laminate, a braided sleeve, and an outer foil laminate, each foil laminate having at least one conductive layer and at least one strength-giving non-conductive layer. At least one of the foils includes a shorting fold to limit the slot effect. Preferably, the inner foil has two conductive layers, and the outer foil has the shorting fold.

Abstract: A centrifugal drying and dedusting process is provided to dedust heavy oil derived from solid hydrocarbon-containing material such as oil shale, coal or tar sand. In the process, heavy oil laden with particulates derived from the solid hydrocarbon-containing material is centrifuged into a dedusted stream of heavy oil and a dust laden centrifuge sludge. The dedusted stream of oil can be further dedusted in a desalter, after being first mixed with fresh water, to form a purified, highly dedusted, effluent stream of heavy oil. Dust laden water from the desalter is centrifuged into a dedusted stream of water and a dewatered centrifuge sludge. The dedusted stream of water is recycled upstream of the desalter and mixed with the influent oil stream. Desirably, the centrifuges sludges are mixed, heated, dried and separated into another dedusted stream of oil and a powdery, dust-enriched residual stream which can be combusted in a lift pipe for use as heat carrier material in the dryer and retort.

Abstract: A heating and drying process for dedusting heavy oil derived from solid hydrocarbon-containing material, such as oil shale, coal or tar sand, without the use of diluents, solvents, chemical additives or mechanical separators, such as centrifuges and filters. In the process, heavy oil is fed to a dryer, such as a screw conveyor dryer or fluid bed dryer, and separated into a dedusted stream of oil and a powdery, dust-enriched residual stream. Preferably, heavy oil residue in the residual stream is combusted to leave a spent stream for use as heat carrier material in both the dryer and retort.

Abstract: A pool cleaning apparatus characterized by a long, hollow main body coupled to a pressurized swimming pool inlet and supporting a pair of cleaning hoses, a pressure relief valve, and an adjustable nozzle for producing a surface current. A primary cleaning hose sweeps the side and bottom surfaces of the pool, and a secondary cleaning hose follows up after the primary cleaning hose. The adjustable nozzle is used to direct a jet of water towards the surface of the water contained by the pool to create surface currents which urge floating debris towards the swimming pool's skimmers. The pressure relief valve controls the strength and vigor of the cleaning action of the apparatus.
