Abstract

918,270. Arc lamps. UNION CARBIDE CORPORATION. Sept. 3, 1959 [Sept. 8, 1958 (2)], No. 30030/59. Class 39 (1). In an arc lamp a high-intensity light source is formed by passing a stream of inert gas of molecular weight greater than 40 over the electrode 122 so that a constricted arc of high temperature and axial stability is formed in the space 130 adjacent the aperture of a constricting passage which restricts the diameter of the arc. A typical embodiment has a water-cooled nozzle 124 and anode 132, and the device is enclosed in a housing 126 which has a window 128 in such a position that the light from the discharge may readily escape from the chamber. The gas which is preferably either Xenon, or Krypton may be kept at a pressure in the range 15-50 atmospheres, although any pressure above atmospheric will suffice, and since the gas is not consumed, it may be connected to pumping means to effect continual recirculation. The discharge arc may be of the " transferred " or " non-transferred " type. In a modification (Fig. 5, not shown) an arc column is established within a water vortex channel which serves to constrict the arc and to cool the surrounding quartz guide tube through which the light from the arc is transmitted. Specifications 845,410 and 845,411 are referred to.
