Abstract:
A method is shown for manufacturing a polyethylene jacket of the type used in pre-insulated piping systems. A mandrel is first coated with a brittle polymeric coating. A melt profile of polyethylene is then extruded onto the mandrel and spirally wound to produce adjacent windings. The adjacent windings make contact to form a finished jacket which is in engagement with the brittle coating. After the jacket has set, an external compressive force is applied to the tubular member thus formed sufficient to crush the internal brittle coating, thereby freeing the polyethylene jacket from engagement with the mandrel. The jacket can then be removed from the mandrel.

Abstract:
Disclosed is method for converting heat energy into electrical energy. The method includes the steps of (1) obtaining heat energy, (2) transferring the heat energy to a gas, (3) transferring the gas containing the heat energy to a compressor, (4) operating the compressor to compress the gas containing the heat energy, thereby concentrating the heat energy, (5) bringing the gas containing the concentrated heat energy into contact with a liquid in a heat transfer device, thereby converting the liquid into steam, (6) converting the heat energy into mechanical energy, and (7) passing the mechanical energy to a generator where the mechanical energy is converted to electrical energy. The present invention can be performed in various structures. For instance, it is possible to break water apart and store it in one or more double-walled containers attached to an automobile, to power the automobile; a non-imaging heat concentrator may be used according to the disclosed method to run utilities, cell-phone antennas.
Abstract:
Disclosed is a smoker device which is effective in imparting a smoky flavor to food as it cooks and is also conveniently portable. The device includes two pairs of opposing vertical panels, each panel having substantially rectangular shape and having four substantially straight edges, and an attachment mechanism located on at least one straight edge of each vertical panel for attaching that side edge to a side edge of an adjacent vertical panel. The two pairs of vertical panels cooperate with hot coals or another heat source, when in operation to form a platform having four top edges and to smoke food. The first pair of vertical panels and the second pair of vertical panels are capable of being folded into a substantially planar shape. A lid covers the top edges of the platform. An adjustable vent is located on the surface of the cover, which in its open position permits maximum smoke to exit the smoker device and in its closed position substantially blocks smoke from exiting the smoker device. A structure for supporting food during the cooking operation, such as an array of spaced-apart bars, is secured the array to the inner sides of the first pair of opposing vertical panels and supports food to be cooked.
