Abstract: A tangentially fired pulverized coal furnace in which the means for introducing fuel and air from the corners operate as independent firing systems at low ratings and contribute to the fireball at higher ratings. The coal flow through a nozzle is deflected radially outwardly at low ratings and allowed to continue essentially straight at high ratings. A surrounding secondary air flow is concentrated at the coal stream and may be varied from a swirling action at low ratings to a parallel flow action at high ratings.

Abstract: A layout for collecting solar energy is described which is made up of modules formed by two or more hollow plates of variable-cross section, placed parallel to each other, in the interior of which a fluid having chemical properties which assist the collection of solar energy flows. The plates are inserted in the mouths of two collectors to which the supply and distribution ducts of the fluid are applied. The collectors have a configuration providing an area or chamber of air separating both plates, and in the opposite side, they have an upper fin, with a "U" cross-section, to fit into the structure of the building, and a lower flange which bears a block made of insulating material placed under the second plate.

Abstract: A solar heating system operating on a phase-change cycle and suitable for operation in buildings. A solar heating panel is positioned to receive solar energy, and fluid passages within the panel are connected in a sealed closed fluid system. The closed fluid system is charged with a fluid medium which is vaporized by solar heating occurring in the solar panel. The heated vaporized fluid flows through energy extraction devices which do work while utilizing energy extracted from the vapor. The vaporized fluid flows to a condensor in heat exchange relation with a heat storage medium, such as a tank of water. The heat of vaporization given out by the condensing vapor is supplied to the heat storage medium, and heat can then be withdrawn from storage for space heating or for other purposes. The solar heating panel can be a composite structure fabricated from rolled sheet metal, which provides a substantial reduction in unit cost of the heating panel.

Abstract: A collector of waves, such as of solar radiations entering from any direction, concentrates them upon a receiver that converts them to useful purposes. Moderate concentration factors are achieved without the necessity of tracking the sun. The reflective surface of the collector is a semicircular arc; developed by rotation about an axis either in the plane of the arc passing through the center of curvature to form a hemisphere, or in the plane of the arc and tangent to one end to form a hemitoroid with a central cusp, or about some other axis; or some combination of these shapes. The device is compounded to provide an increased concentration factor. Means are taught for adapting the device to heat-collecting plates, heat pipes, or photovoltaic conversion devices (solar cells) of either disc, ribbon, or tube construction and for installing the device on surfaces of buildings with or without the capability of tracking the sun.

Abstract: A horizontally mounted solar collector for collecting solar energy utilizing a vertical deflector assembly, a stationary reflector and a collector.

Abstract: For the simple Thomason "SOLARIS" heat collector, a simple outlet is used that requires a drop-outlet nipple with a U-slotted top end, and sealant to avoid escape of liquid or steam (vapor).In a modification, only one drop outlet is used for two "SOLARIS" panels, thus cutting the cost even further.In another modification a slotted, sloping pipe serves as an outlet and drain.

Abstract: The invention adds liquid solar heating to conventional house construction without altering the plans. Sections of moulded polyester resin embedding p.v.c. pipes connect together to provide a continuous liquid pathway which is hidden from view. The sections are artistically styled, obviating the unsightly appearance of present day solar equipped homes. The arrangement is very inexpensive, yet durable, and not subject to glass panels and its attendant breakage or the use of expensive copper tubing. The entire roof is a collector and different parts of the roof are exposed to the direct sunlight at all times of the day.The solar sections actually replace the shingles, tile or other outer coating of the conventional roof for new construction. Hence, the solar section is integral with the house, making it more stormproof, yet workmen may walk over the roof.
