Abstract: The upper panel of a tailgate assembly is moved in a downward and rearward convexly curved path between an upward and forward position and a rearward and lowered position and the lower panel is rotated forwardly and rearwardly with respect to the upper panel. Linkages are included in the tailgate assembly to provide this movement. A lower surface of the fixed panel may have an upwardly curved lower surface which imparts a forward direction of movement to refuse which is packed against it. The upper panel may have a curved forward surface in close proximity to a rearward surface of the fixed panel. During movement of the upper panel, the rearward surface of the fixed panel removes refuse from the curved forward surface. The upper panel is tilted as it moves and during its upward movement the lower portion of the upper panel is tilted forwardly. This imparts a forward movement to refuse which is moved through the opening into the storage body. The hopper may include a vertically inclined forward packing surface so that refuse is packed between the curved packing surface and the vertically inclined forward packing surface of the hopper. The hopper may include a straight rearward wall portion with the packing panel having a narrowed lower edge. During its movement into the hopper, the packing panel may be moved so that its narrowed lower edge is in contiguous relation to the straight rearward wall portion of the hopper. The packing panel may include one or more upstanding ribs on its curved packing surface which provide a reduced area for application of high localized pressures to refuse contacted by a rib.

Abstract: An integrated system for engine heat extraction and comfort air conditioning in an automotive vehicle powered by a Stirling engine, the system being used (a) as a part of the heat rejecting means for the Stirling engine located in a compartment outside of the passenger compartment, and (b) for conditioning air within the passenger compartment. The heat rejecting means of the Stirling engine is effective to cool a selected zone of an enclosed working fluid circuit of the engine; the heat rejecting means is divided into two portions, one normally being diposed to reject heat to ambient air conditions and another disposed to selectively impart rejected heat either to air flow for conditioning air for said passenger compartment or to air flow to be aborted to ambient air conditions. The embodiment as disclosed further includes evaporation or heat absorption means and controls therefore to blend dehumidified cooled air with the air warmed by said heat rejection portion to render a total air conditioning system for the passenger compartment which relies in part upon the heat rejection means being continuously employed as an element of the Stirling engine. In another embodiment, the air conditioning system is arranged with appropriate controls to recirculate cool, dehumidified air to the heat rejection means for a reheating cycle before entering the passenger compartment; an ambient dump control is again employed so that the heat rejection means may be maintained in constant operation.

Abstract: The present invention relates to a process for the selective separation of uranium and molybdenum which are contained in an extract resulting from an amino solvent liquid-liquid extraction of a solution resulting from an attack on a molybdo-uraniferous ore by means of sulphuric acid, and which comprises re-extraction of the uranium in the presence of an oxidizing agent by means of an acid solution of an alkali metal chloride, followed by re-extraction of the molybdenum by means of an alkali metal carbonate solution. This process is characterized by using an oxidizing agent such as hydrogen peroxide, a small amount of which is added to the acid alkali metal chloride solution before the latter is brought into contact with the extract. This makes it possible to achieve selective separation of the uranium and molybdenum. This process can be used wherever molybdo-uraniferous ores are treated and where there is a requirement to produce a uranium concentrate which complies with the limits set in regard to the molybdenum content.

Abstract: A liquid crystal cell having memory is provided by disposing a liquid crystal material having nematic directors between two substrates which are fabricated to contain an array of singular points. The cell may further include means for detaching singularities such as appropriate electrode arrangements. These substrate configurations provide multistable configurations of the director alignments because disclinations must be moved, either through the bulk of the liquid crystal material or on the substrate surfaces to switch between the stable configurations. The switching of the device between stable configurations may be accomplished by the application of electrical fields to the liquid crystal material. The stable configurations may be optically differentiated by the incorporation of pleochroic dyes into the liquid crystal material or by crossed polarizers.

Abstract: The invention concerns a method for flash welding, in which when welding two parts they are made to progressively approach each other and the ends of the parts are melted by means of alternating current, while at the same time an oscillating motion along the direction of approach is imparted to one of the parts, thereby accomplishing an additional relative motion of the parts being welded together to and from each other, with the result that the spark gap and the resistance of the contact bridges between the parts will vary. When the resistance across the contact bridges exceeds a predetermined value, the welding voltage is reduced to within the range of 0.7-0 of its working value. The voltage can also be reduced to within said interval during the relative motion of the parts away from each other for a time interval of at least 1/8 of the period for the part's oscillating motion and restored during the relative movement of the parts toward each other for a time interval of no more than 1/8 of the period of the oscillating motion. <IMAGE>

Abstract: A method and apparatus is disclosed for reducing entrainment of fines of feed stock material in tar- laden gases produced by a rotary kiln in the gasification of coal or other carbonaceous material. The fines and tar are both separated from the gas and from each other. The separated fines are recycled by admixing and churning such fines with newly provided solid carbonaceous feed material and recycled tar in a screw conveyor (8) prior to introduction of such mixture into the kiln (6). The mixing and churning action in the conveyor (8) causes the tar to coat particles of the newly provided feed material with tar and thereafter cause the fines to adhere to the tar-coated particles to form a composite agglomerate thereof. Such agglomerates when discharged into the kiln (6) by the conveyor (8), will travel a greater distance into the kiln (6) and away from the gas outlet (17) than the distance travelled by discrete fines. Fines adhering to the tar-coated particles as part of a composite agglomerate are, therefore, less likely to be carried out of the kiln by gas flow prior to gasification of such fines than are discrete fines. <IMAGE>

Abstract: To form a shaped foundry core or mould, a binder material comprising an ethylenically unsaturated monomer or polymer is distributed on a foundry aggregate, the aggregate is shaped into the desired foundry article, and the binding material is then polymerised by means of a free radical initiator comprising a peroxide and catalytic agent. The binding material is preferably a solution of an ethylenically unsaturated polymer in a solvent of unsaturated monomeric compound or compounds, in which vinyl or acrylic unsaturation is present. This binder is suitable as a foundry binder of the cold box type wherein a room temperature, rapid gas cure is utilized. The gas, preferably sulfur dioxide, serves as the catalytic agent of the free radical initiator. Alternatively the catalytic agent may be heat. The binder collapses readily after casting of aluminium and other lightweight metals to provide complete shakeout of the core with minimum application of external energy.
