Abstract: A liquid medium solar heating system especially suitable to effectively capture intermittent and/or low intensity solar radiation as in cooler and/or cloudier climates. The system employs a quick response liquid storage having a capacity equal to only a small fraction of the capacity of the main storage with which it is combined. Temperature responsive flow control means causes preferential heated liquid flow from the collector to the quick response day storage, creating a usable thermal driving potential of a substantial temperature differential between heat exchange liquid in the day storage unit and the environmental space to be heated. Valved conduits between these components, and a pump cooperative therewith, achieve temperature responsive flow for optimizing heat salvage.

Abstract: There is disclosed herein a forced air solar heating system which causes selectively operated multiple air blowers in combination with multiple ducts and control dampers to operate in response to heat sensors in the space to be heated, and in a solar collector, and in a storage chamber, to transfer heat from the collector to storage, or to controllably transfer heat to said space from the collector or from the storage, but also alternatively as mixed heated air from both the collector and the storage, to a mixing chamber and then to said space. The air propelling blowers, the flow control dampers, and the mixing chamber are preferably all part of a unitary air handler.

Abstract: A forced air, solar heating system employing dual air movers and dampers, such air movers being selectively operable in tandem or separately, in conjunction with a solar collector and a storage unit for heating a space. The air movers and dampers are operable to transfer heat from the collector to storage, or from the collector to the space, or from storage to the space, or in special fashion from both the collector and the storage to the space, for efficient heat salvage.

Abstract: A solar collector assembly having within its housing a series of radiant energy entrapping collector elements, each having an energy absorbing base, a generally semicylindrical upwardly open reflector with concave, upper, receptor-reflector surfaces and convex lower receptor surfaces, a collector and radiation entrapping receptor projecting up in said reflector into the radiation reflection pattern of the concave surfaces. These elements form elongated fluid flow heat exchange passages.

Abstract: A foldable furniture unit employing scissors-acting seat frames and upright side frames has restraining members on the seat rail portions of the seat frames adapted to be positioned adjacent portions of the side frames to reduce relative movement between the seat rails and the side frames and thereby stabilize the unit when it is in unfolded condition for use. The restraining members preferably are provided by cap-like members which are also capable of at least partially closing welt and core receiving slots in the seat rails by which a flexible seat web is secured to the seat rails.

Abstract: A novel electronic transceiver that alternatively performs either as a voltage-to-frequency (V/F) converter or as a frequency-to-voltage (F/V) converter. The transceiver can selectively be operated in either of the two modes by appropriate terminal connections which cause the transceiver to perform in the particular mode desired or necessary. The transceiver includes an analog integrator, a voltage follower, and a charge transfer circuit interconnected and having selectable terminals for external connections whereby the circuit performs selectively in either the V/F mode or the F/V mode.

Abstract: A dispenser container wherein magnetizable needles, tools, or the like, are mounted upon a magnet element secured pivotally to the interior of the container by means of a fabric hinge. The pivoting motion of the magnetic bar is produced by the alternating forward and retracting movements of the cover or closure element for the container whereby the needles move into a substantially horizontal position when the container is closed. When the cover is retracted, the pivoting motion of the magnet induced by gravity causes the needles to move pivotally whereby the freely extending forward portions thereof extend externally of the container to facilitate individual selection.

Abstract: A system and apparatus for separating different types of particulate materials selectively by subjecting a moving mixture of said materials to a combined applied direct current (D.C.) voltage and radio frequency (RF) electric field, thereby causing the particles to become differentially heated in accordance with the respective dielectric constants and loss factors of the various particles. The separation is accomplished as a result of the differential loss of electrostatic charges impressed upon the different types of materials in accordance with their respective physical and chemical characteristics. During this process, there is no permanent or irreversible alteration in the chemical and physical properties of the particulate materials.

Abstract: The system and apparatus herein incorporate means for effectively and significantly reducing the liquid components of the fuel mixture passing through a cylinder located between the carburetor and the intake manifold of an internal combustion engine. The invention includes a stationary circular array of radially arrayed overlapping slanted spaced baffles or blades located in the fuel stream. Formed or otherwise mounted on the lower or trailing edge of each blade is a radially extending flange or scoop which catches and projects liquid components from the fuel stream through a corresponding aperture in said cylinder and into a collection chamber surrounding said cylinder. The collection chamber contains a reticular, webbed, or porous material for retention and drainage of the excess liquid components. Additional means are provided to restore a desired quantity of liquid fuel to the fuel stream when the engine requires temporary surge or demand power.

Abstract: The system and apparatus herein incorporate means for effectively removing significant quantities of liquid components from the fuel mixture while the latter passes from the carburetor to the intake manifold of an internal combustion engine, and for recovering said liquid components and recycling them through the fuel supply system in order to effect appreciable savings in fuel consumption during operation of the engine. The invention includes means for centrifuging liquid components from the fuel stream into an adjacent collection chamber whence said liquids move continuously into a drain tank which maintains a closed system with the collection chamber. The capture of liquids in the collection chamber may be improved by incorporating a reticular packing therein. Additional means are provided to restore a desired quantity of liquid fuel to the fuel stream when the engine requires temporary surge or demand power.
