  • Patent number: 4281502
    Abstract: The disclosed cover, carrier and package for one or more articles, is formed from a sheet of material which is stretchable when softened but relatively rigid otherwise. In a preferred apparatus and process, such a sheet is positioned over the top of the object to be covered and the portion of the sheet directly over the object is softened. A downward force is applied to the unsoftened, still relatively rigid portion of the sheet so as to force it down and around the top of the object. This causes the softened portion of the sheet to be stretched over the top and down the side of the object, conforming closely to it and thus providing a tight seal. By covering multiple articles a carrier may be formed. Methods for controlling the thickness of different parts of the carrier are described. In addition, a carrier may be applied to both the top and bottom of an array of articles in order to form a rigid carton or case.

  • Patent number: 4281511
    Abstract: A turbine engine operates at high pressure and at relatively low temperatures and revolutions per minute through the use of special carburetion, compressor, combustion unit, and turbine arrangements. The system is characterized by the use of water which is vaporized and concurrently reduces the temperature of the vaporized fuel and air mixture as compression occurs, and is not physically intermixed with the combustion gases until after initial combustion takes place. The compressor includes a pair of back-to-back, four stage composite compressors to which synchronized dual carburetion or meter-flow arrangements separately supply water and gasoline or other fuel, along with air. The water absorbs heat from the compression of both of the two compressors, and the resultant vaporous product gases are routed to the jacket of a combustion chamber in which the compressed fuel and air mixture is burned.

  • Patent number: 4281513
    Abstract: A heat engine employing a memory alloy and a force field such as gravity for converting heat energy into mechanical work. Field effect elements are mounted on the distal ends of flexible spokes which in turn are mounted about a hub to form a rotating wheel. The memory alloy is in the form of a helix disposed about the circumference of the wheel and interconnecting the ends of adjacent spoke pairs. Heat is transferred to segments of the memory alloy on one side of the wheel so that the segments deform toward their memory shape and deflect the associated spokes toward each other. Heat is transferred away from the memory alloy segments on the opposite side so that the segments deform toward their trained shape and permit the spokes to flex apart. The concentration of field effect elements onthe first side of the wheel is greater than the concentration on the other side so that the resultant force created by a remote field acts as a torque for rotating the wheel.

  • Patent number: 4281517
    Abstract: A single stage, twin piston cryogenic refrigerator for cooling supercondung devices. The refrigerator uses helium as the heat transfer medium and is constructed with two nested, concentric pistons, an inner piston and an outer piston, mounted in a cylinder and driven 90.degree. out of phase by a common crankshaft. The inner piston extends through and below the outer piston and is received in a stationary insert mounted in the cylinder. The outer piston has a first piston face which forms a compression space with the stationary insert while the inner piston has a second piston face which forms an expansion space with the cylinder and the insert. The inner piston is formed with upper and lower piston halves joined by a flexible joint positioned in the compression space. Cylindrical regenerator gaps are present at the interface of the inner piston with the stationary insert and at the interface of the stationary insert with the cylinder.

  • Patent number: 4281518
    Abstract: A method of separating certain components of a gas mixture in which the gas mixture is cooled and certain components are separated in a liquid or solid state characterized by introducing the gas mixture into a separator tank, adding a cooling agent such as a liquid or cold inert gas so as to cool the gas mixture and separating component in a solid state and subsequently fusing the separated solid into a liquid in a collecting tank. The concentrated gas mixture to be separated is directly removed from its place of use and directly supplied to the separator tank without allowing any further admixture of secondary air. The device for carrying out the method comprises an insulated tank to which air having entrained sulfer dioxide is introduced. The air flow is controlled so that it is oriented in a particular direction and it is passed beyond nozzles for injecting an inert gas such as liquid nitrogen into the interior of the insulated tank.

  • Patent number: 4281521
    Abstract: Articles of food to be frozen are delivered to an article conditioning conveyor and are maintained in a fluidized state by refrigerated air flowing upwardly therethrough. The conveyor is driven forwardly but is interrupted by at least one downward stepping movement, causing a thinning of the product bed and a rapid increase in air velocity to thus cool and separate the food articles preventing them from freezing to one another. The food articles are thereafter subjected to deep bed mass fluidization by flowing freezing air therethrough in a fluidized state.
