Abstract:
A segment display system where ultraviolet energy is generated and contacts with fluorescent material coatings to provide a visible output through fluorescent excitation of the fluorescent material coatings. Ultraviolet energy is generated through the ionization of metallic atoms from a metallic coating which is formed on through opening sidewalls of slots defining a cathode mechanism. The slot through openings are aligned with fluorescent material coatings formed on a display panel member. Below the cathode mechanism is a common anode element. Each of the metallic coatings formed within each of the slot through openings is coupled to an external electrical source in a manner similar to the anode element being so coupled. The segment display system is formed into a monolithic structure which includes an internal chamber within which an inert gas is introduced. Electrical energization of the cathode elements and the anode element result in ionization of metal atoms emitted from the metallic coating. The ionization process provides for ultraviolet radiation which is directed to the fluorescent material coating. The coatings are generally linearly extended and are formed into a predetermined pattern in order to provide visible information output such as numerical digits.
Abstract:
ELECTROMAGNETIC ENERGY ABSORBER There is disclosed an electromagnetic energy collector assembly (14) in which a transparent cylindrical glass tube (40) made from common glass tubing lengths is sealed under vacuum at one end to an inner cylindrical energy absorber (43) having a plurality of grooves (44) on the exterior surface. The inner absorber (43) 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 (14? 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 (14) is particularly useful in the collection of solar energy. MR525-5
Abstract:
Luminescent structure, with a self-supplying and/or independent radiation source (I) to effect luminescence, has an absorbing material (II) capable of absorbing a fluid which can emit radiation. This is placed near the luminescent material (III) and provides radiation continuously. Pref. (I) is tritium and (II) is Pd, Ti, Zr, Nb, Ta, Fe or alloys of these, esp. Zr in the form of numerous particles in a matrix. The source can withstand rough handling and can be produced easily and at relatively low cost. It can provide a relatively high level of illumination over a relatively long period.
Abstract:
An improved lighting system (10) which in the preferred embodiment includes a cathode (12) having an external surface (34) being coated with a cathode outside film (40) for emitting electrons therefrom. A first anode (14) extends internal to the cathode (12) for heating the cathode (12) to thereby emit electrons from the external surface (34). A second anode (16) is positionally located external to the enclosed cathode (12) for accelerating the electrons emitted from the cathode external surface (34). A bulb member (18) encompasses the cathode (12), the first anode (14), and the second anode (16) in a hermetic type seal. The bulb member (18) has a predetermined gas composition contained therein with the gas composition atoms being ionized by the cathode emitted electrons. The gas composition ionized atoms radiate in the ultraviolet bandwidth of the electromagnetic spectrum. The bulb member (18) is coated with a fluorescent material (20) for intercepting the ultraviolet energy responsive to the ionization of the gas composition atoms. The fluorescent material (20) radiates in the visible bandwidth of the electromagnetic spectrum to give a visible light output.
