    Abstract: An electronic ballast system includes a first capacitor (C.sub.2) electrically coupled to the first filament (30) of a gas discharge tube (12) and becomes the power supply of the gas discharge tube (12) subsequent to both its charging and discharging operations. The collector (38) of a transistor (Tr) is connected to the first capacitor (C.sub.2). The primary winding (22) is connected to the first capacitor (C.sub.2) and the collector (38) of the transistor (Tr) in parallel relation. The transformer (t) includes a secondry winding (24) which is connected on opposing ends thereof in feedback relation to the base (44) and emitter (42) of the transistor (Tr). Pulses of opposing current polarity (122 and 124) generated through the secondary winding (24) alternately provide conducting and non-conducting states for transistor (Tr) to discharge and charge the first capacitor (C.sub.2) through gas discharge tube (12) to provide a power source for operation of gas discharge tube (12). The combination provides voltage limiting preventing the kick back voltage from the primary winding (22) to exceed a safe operating limit of the transistor (Tr) and allows use of the energy to produce visible light output instead of heat.

    Abstract: A monochromatic and polychromatic display system (10) which is operative by the generation of ultraviolet energy impinging on fluorescent material compositions (54) in order to create electromagnetic wave generation within the visible bandwidth of the electromagnetic spectrum through fluorescent excitation of fluorescent material (54). The operative ultraviolet energy produced results from the ionization of metallic atoms from a metallic coating (28) applied to cathode opening sidewalls (26) of a cathode mechanism (12). The display system (10) includes a matrix of cathode openings (22) formed in a cathode plate member (14). The cathode openings (22) define the cathode opening sidewalls (26) which have a metallic coating (28) applied thereto. The sidewall metallic coatings (28) and additionally, the metallic coating annular portion (30) of each hollow cathode cavity are coupled to a next succeeding cathode element in a linear column direction (32). A matrix of anode elements (46) are mounted below the cathode plate member (14) and are axially aligned with the cathode openings (22). The display system (10) is formed into a monolithic structure which includes an internal chamber (66) within which an inert or combination of inert gases is introduced. Fluorescent material compositions (54) are positionally located in aligned relation above cathode openings (22). Electrical energization of the cathode elements and the anode elements (46) results in ionization of metal atoms emitted from the metallic coating (28). The ionization process provides for ultraviolet radiation which is directed to the fluorescent material composition (54).

    Abstract: There is disclosed an electromagnetic energy collector assembly in which a transparent cylindrical glass tube made from common glass tubing lengths is sealed under vacuum at one end to an inner cylindrical energy absorber having a plurality of grooves on the exterior surface. The inner absorber may be constructed of glass, metal, or other material and the energy absorbing surfaces have grooves which may be helical, or parallel or longitudinal to the normal axis of the absorber. One or more of energy collectors are connected into a manifold for circulation of a fluid working media, e.g., gas or water, which is eventually utilized in any application of thermal energy, e.g., heating, cooling or driving a turbine. The collector assembly is particularly useful in the collection of solar energy.
