  • Patent number: 4651048
    Abstract: A high-pressure discharge lamp provided with a cylindrical shield near an end and around and at a certain distance from the discharge envelope. The cylindrical shield is electrically insulated from current-conveying parts, so that migration of filling constituents through the wall of the discharge envelope is counteracted.

  • Patent number: 4479071
    Abstract: The invention relates to a high-pressure metal halide lamp in which the filling of the discharge vessel also comprises an alkali metal. The discharge vessel is surrounded by an outer envelope. One electrode of the discharge vessel is connected to a current supply conductor extending between the discharge vessel and the outer envelope. A plate-shaped element is mounted between the discharge vessel and the outer envelope in such manner that, viewed from the discharge vessel, the current supply conductor is present substantially entirely behind the plate-shaped element.According to the invention, the plate-shaped element comprises boron nitride.Increase of the arc voltage of the lamp and increase of the color temperature of the radiation emitted by the lamp is prevented in this manner.

  • Patent number: 4221987
    Abstract: The high-pressure electric discharge tube of the invention can operate in the open air, with at least 10 Hg mm inner pressure. It has a preferably ceramic (or crystalline) envelope that constitutes an illuminator, with electrodes disposed in two opposite portions of the envelope, appropriate inlets, lead-ins and terminals leading to the electrodes. The discharge tube does not have to be surrounded by the hitherto applied, conventional, glass or other transparent protective envelope, as a result of which the emitted luminous output is free from reflections and the tube can be used throughout the entire spectrum, such as for pumping or driving a laser crystal. The protective envelope, which so far has been an indispensable part of all high-pressure discharge tubes, has been eliminated as a result of the present invention. Adapter tubes are used that prevent oxidation of the electrical elements, as well as specially configured electrodes.

  • Patent number: 4156163
    Abstract: A travelling wave tube of the coupled cavity type including a slow wave propagating structure comprised of a linear array of transverse plates axially spaced apart to provide a sequential series of interposed cavities, each of the plates having a cavity coupling aperture radially spaced from an electron beam transmitting aperture and spanned by at least one thermally conductive, dielectric member made of diamond material, which has respective surface areas disposed in thermal contact with opposing side walls of the cavity coupling aperture.

  • Patent number: 3992642
    Abstract: A metal vapor arc lamp comprises an alumina ceramic arc tube having an end sealed by an apertured ceramic plug. A metal lead wire extending through the aperture is sealed therein, and supports an electrode within the arc tube. Thermal isolation of the lead wire seal from the electrode is necessary and is achieved by providing a loop in the supporting conductor intervening between the electrode and the lead wire seal region.

  • Patent number: 3989970
    Abstract: A metal halide high-intensity arc discharge lamp having a bulb containing elongated electrodes of a refractory metal such as tungsten, and means connecting the electrodes through seals of the bulb to external terminals. Cooling means such as metal fins are provided at the external terminals and function to cool the electrodes relatively quickly whenever the arc discharge terminates, without substantially affecting the desired high operating temperature of the electrodes. The faster cooling of the electrodes upon termination of the arc discharge permits the lamp to be restarted sooner.

  • Patent number: 3974410
    Abstract: A high intensity sodium vapor lamp comprises a tubular envelope of alumina ceramic provided with end closures and containing a charge of sodium mercury amalgam in excess of that vaporized during operation. One closure includes a refractory metal tube sealed off at its tip and wherein unvaporized excess of amalgam collects as a liquid pool. In order to have a sufficiently high temperature at the amalgam pool, a metal slug of high heat conductivity such as molybdenum is placed in it and extends from the seal region towards the tip. Such slug also prevents overheating the seal between the ceramic tube and the end cap.

  • Patent number: 3970883
    Abstract: The heat-transfer capability of a movable-electrode gas-filled arc lamp is optimized. In the preferred embodiment, the movable electrode is the anode which is mounted at the base of the lamp coaxialy with and spaced apart from the cathode. Low-voltage starting of the lamp is provided by solenoid means for moving the anode briefly into contact with the cathode and then withdrawing the anode from contact with the cathode so that a difference of electrical potential develops between the cathode and the anode, which is sufficient to ionize the gas in the gap formed therebetween. The arc thereby generated in the gap follows the withdrawing anode to its fully spaced-apart position with respect to the cathode. A heat sink member is disposed within the gas-filled envelope at the base of the lamp, and a metal collar is affixed to and surrounds the movable anode. The collar provides thermally conductive contact with the heat sink member when the anode is in its fully spaced-apart position with respect to the cathode.

  • Patent number: 3949263
    Abstract: Diamond heat sink members are now employed to conduct thermal energy from slow wave structures in traveling wave type interaction devices to permit operation at high power levels. The diamond members are bonded to adjacent desired components by a method including heating an intermediate metal alloy of an inactive conductive metal and a small amount of a carbide constituent in a vacuum and the application of pressure. A critical temperature slightly above the melting point of the alloy of between 1000.degree. C and 1100.degree. C is required to wet and bond the alloy material to the diamond and any desired surface.
