Abstract: A heat exchanger in which the main component is formed of a plurality of elongated strips of rigid heat conductive material. Each of the strips has a cross-sectional configuration which is elongated in a direction transverse to the elongated extent of the strip so as to provide a pair of spaced relatively thin end edges and a pair of relatively wide opposed surfaces extending between the end edges. The strips are generally transversely aligned and wound into a coil formation in which each of the surfaces of each strip is disposed in facing relation to the opposite surface of an adjacent strip in the coil.

Abstract: A heat exchanger for a multiple fluid medium solar energy system comprising a plurality of elongated strips of heat conducting material secured together to define a plurality of elongated passageways of uniform cross-section extending parallel to one another in the direction of elongation of said strips and wound spirally in a coil formation in a direction such that the passageways extend along side-by-side spiral paths. Sealing material spacers are provided between portions of the spirally wound strips defining adjacent volutes at two annularly spaced positions with respect to each spiral path through which first and second bores extend in generally radial direction of a number equal to the number of spiral paths.

Abstract: A method and apparatus for extruding a radiant energy heat exchanging panel structure having a multiplicity of parallel passages extending longitudinally therethrough defined by a multiplicity of longitudinally extending integrally interconnected exterior and interior thin wall sections, in which the temperature of the plastic material moving longitudinally away from the extrusion outlet is reduced by flowing fluid into said passages and on the exterior sides thereof, by contacting the exterior sides with pairs of cooled rollers, by rolling a liquid medium upon the operative exterior side, and by flowing a liquid spray thereon to provide a radiation absorbing coating on the exterior side of the panel structure opposite from the operative side thereof. Certain of the flowing fluids are reactant fluids which chemically react with the hot plastic material or condense thereupon to form molecular coatings thereon enhancing the properties thereof as a panel structure.

Abstract: Method and apparatus for providing improved combustion in an internal combustion engine by spark-ignition of fuel that is directly injected into cylinders to present a stratified fuel-air mixture at time of ignition. Reduced mixing of the fuel and air prior to ignition and thus greater stratification permits improved control of the combustion process to increase power and reduce pollutant emissions.
