Abstract: A precast concrete solar collector panel of moldable hardenable material is developed with a serpentine-like passageway disposed in proximity to at least one planar surface of the panel. The passageway serves as a conduit for conveying a fluid to effect a heat transfer intermediate the proximate planar surface of the panel and the fluid rendering the panel useable as a heat collector or as a source of radiant heat, depending upon the relative temperatures between the conveyed fluid and the proximate planar surface. By constructing the panel as a structural member, a plurality of panels can be employed as a roof, exterior building wall, walkway, driveway or fence to receive radiant energy from the sun and transfer the collected heat to the fluid flowing within each of the panels; further panels can be employed as interior walls, ceilings or floors in buildings as sources of radiant heat by passing a heated fluid through the passageways.

Abstract: A process and apparatus for collecting solar energy involving exposing a mixture of a fluid carrier and heat absorbing particles to the rays of the sun in a container having a transparent cover facing the rays of the sun, and circulating the mixture to a thermal accumulator or sink. The fluid may be a liquid or gas, or a mixture of liquid and gas; and the particles preferably have a specific gravity different from that of the carrier so they naturally separate if circulation of the mixture stops. The container is dimensioned so that, upon separation of the particles, they no longer are exposed through the transparent surface of the container. Mixture flow control means are provided within the container.

Abstract: A sinuous pattern of soft copper tubing is pressed against a laminated assembly consisting of a thin sheet of copper laminated to a layer of insulating foam which is in turn laminated to a backing plate of pressed wood. As the pressure is increased, the tubing deforms the copper sheet in conformity with the shape of the copper tubing. The foam resists deformation of the sheet in areas not directly beneath the copper tubing resulting in a well-defined trough adapted to receive the copper tubing which deforms it. The copper tubing and sheet are then bonded together resulting in a thermally efficient, inexpensively produced collector panel.

Abstract: A modular heating section for removing or preventing the formation of ice on the walls of navigation locks, loading docks, ferry slips, or the like. Ice formation on the walls of navigation locks is compressed by successive vessels to the extent that larger vessels are unable to enter the locks. To avoid this happening, ice is chipped from the walls of the locks, which is time-consuming. As well, chipping of the ice results in damage to the concrete walls which must then be repaired. To overcome this problem, the present invention proposes the use of a modular heating section comprising a rigid panel having means for securing the section to a navigation lock wall, loading dock, or the like at a location where ice formation occurs, the panel being made from a heat conducting material. The panel includes heater means situated therein, the heater means adapted to distribute heat throughout the modular heating sections.

Abstract: An improved method and apparatus for forming glass fibers is disclosed. The environment below the bushing is controlled by a pair of manifolds through which a cooling fluid flows. This cooling fluid additionally is employed to cool the various apparatus surrounding the bushing. The cooling fluid enters the manifolds through a plurality of entrance connections and exits the manifolds through a plurality of exit connections. The exit connections are connected to the various elements of the bushing apparatus and allows cooling fluid to flow through these elements. The cooling fluid is then returned to the manifolds by a separate set of entrance connections, flows through the manifolds, and again exits the manifolds through another set of exit connections to return to the fluid circulation system.
