Abstract: 367,891. Discharge lamps. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Weinhart, H. W. ; 61, Dayton Street, Elizabeth, New Jersey, U.S.A.) Nov. 27, 1930, No. 35716. Convention date, Dec. 31, 1929. [Class 39 (i).] A cathode glow is produced in a narrow elongated passage formed in the cathode and open at both ends, the anode being in close proximity to one end of the passage, and the beam projected from the other end. As shown in Fig. 2, the cathode 25 has a cvlindrical passage 27 and a cup-shaped extension 26 within which a disc or plate anode 28, mounted in insulating cement 30, is spaced by an insulator 29. The cup is supported by metal strips 24 from a collar 23. In a modification, the cathode consists of a metal tube embedded in insulating material in which the anode is mounted. As shown in Fig. 8, the cathode consists of a metal thimble 44 cooled by an internal circulation of liquid and having a capillary opening 45, at one end of which the anode 28 is mounted; or the cathode may consist of an externally threaded cylinder mounted in the thimble. In other modifications, (a) the cathode has heat-radiating plates, (b) the passage consists of a narrow slit of rectangular section, and (c) the anode had a conical recess.
