Abstract: The novel radiation source system of this invention includes a pair of electrodes which are coaxially mounted at each end of a single cylindrical transparent arc chamber. A liquid, such as water, is circulated through the arc chamber with a tangential velocity so as to form a vortexing liquid wall. The main functions of the liquid wall are to cool the periphery of the arc discharge between the electrodes thus constricting the arc diameter, and to absorb ultraviolet and infrared radiation which would otherwise be absorbed by the outer solid wall. This liquid wall produces a positive dynamic impedance for the arc discharge. In addition, a vortexing column of inert gas, injected through the length of the chamber, stabilizes the arc discharge between the electrodes. In one embodiment, the structure of the anode electrode includes an annular constriction which is mounted near the anode surface to constrict the diameter of the arc column near the anode and to form a gas expansion chamber adjacent to the anode surface wherein the inert gas on expansion loses its vortex motion. The arc is therefore no longer vortex stabilized and current density at the anode surface is reduced. In a further embodiment, the anode structure includes an expanding chamber at the anode into which both the liquid and the gas lose their vortex motion. A 3-stage starting and power supply circuit is connected across the electrodes. It includes a pulsing circuit to initiate the arc discharge across the fixed electrodes and a programmed capacitor bank to sustain the arc until such time that the main power supply, with its inherent high inductance, provides sufficient current to the radiation source to maintain the arc.

Abstract: The mercury-vapor pressure within a fluorescent lamp is controlled by a metal (indium or an alloy of indium and tin, for example) that wets glass, combines with the mercury within the lamp to form an amalgam and is divided into segments which are fused directly to one or both of the glass stems at spaced locations. The amalgamative-metal segments are of such shape and mass that they inherently remain in place on the stem when they are heat-softened and pressed onto the glass surface. Segments of larger size and mass are retained in place by an overlying porous layer of inert material that adheres to the glass or by an embedded wire mesh member and an exterior porous coating of inert material. The amalgamative metal can also be combined with a fusible binder to form a composite which is divided into small pellets that are pressed onto the glass stem and held in place by the adhesive action of the binder when the latter is fused during the bulb-lehring operation required to fabricate the lamp.

Abstract: A very high output fluorescent lamp having an electrode mount structure sealed in each end which includes a cathode coil supported on a pair of lead wires. At least one of the mount structures further includes a heat shield plate attached thereto and supported transversely in the tubular lamp envelope between the cathode coil and its respective end of the lamp. A quantity of amalgam-forming material, such as indium, is coated on the side of the heat shield plate facing away from the cathode coil and toward the end of the lamp for absorbing mercury when the lamp is turned off, holding the mercury on the heat shield while the lamp is inoperative, and, when the lamp is ignited, quickly releasing the mercury into the relatively cool end chamber of the lamp.

Abstract: An improvement in an arrangement for the introduction of materials into a closed electric discharge vessel. The arrangement includes a closed holder containing preselected material to be introduced into the vessel and a secondary coil element placed in contact with the holder which element includes a heating wire for decomposing the wall portions of the holder. The heating wire is activated by the induction of current in the secondary coil by a primary coil which is external to the electric discharge vessel. The invention encompasses improvement in the shape of the holder and the positioning of the holder. A particular embodiment of the invention involves constricted portions of the holder which cooperate with lugs extending from a strip-shaped secondary coil section. This arrangement effects substantially improved positioning of the holder after the materials within the holder are released into the vessel.

Abstract: An atomic spectral lamp includes a demountable, hollow cathode, and a funnel-shaped anode adjacent to the cathode. A glow discharge plasma is established in the cathode cavity. Counterflow through the funnel-shaped anode prevents self absorption of light by atomic vapor. Gas flow through the hollow cathode at a predetermined velocity increases the intensity of light-emitted from the plasma.

Abstract: A closed cycle depressurization system including a lamp envelope for containment of a discharge gas at greater than atmospheric pressure in communication with a gas storage and depressurization chamber. A substantially transparent material, potentially frangible at said pressure forms at least a portion of the envelope. In one embodiment, depressurization is effected by externally cooling the walls of the chamber and in a second embodiment the chamber contains a gas adsorbent which adsorbs gas to reduce the pressure in the lamp envelope to the desired safe nonoperating level. Repressurization is accomplished by raising the temperature of the chamber and the stored gas and recycling the gas to the envelope.

Abstract: The time required for an amalgam-regulated fluorescent lamp to stabilize and reach its rated light output under ''''cold-start'''' conditions is reduced by providing a small auxiliary body of amalgam on a selected portion of a metal conductor that is attached to one of the electrode structures within the lamp and is so arranged that it serves the dual function of a ''''failsafe'''' component. The auxiliary body of amalgam is so located with respect to the adjacent cathode that it is rapidly heated and releases mercury vapor as soon as the lamp is energized. The ''''fail-safe'''' conductor is preferably made of wire mesh or sheet metal and provides a conductive path from one of the leads to the stem which causes an arc to impinge upon and puncture the stem when the cathodes are devoid of emission material and the lamp has thus reached the end of its useful life.
