Abstract
777,084. Cathode - ray oscilloscopes. LORENZO, U. DE. March 15, 1955 [April 2, 1954], No. 7452/55. Class 40(7) The cathode-ray tube 5 of an oscilloscope is supported in a magnetic shield casing 11 which is mounted at one end by a ball and socket joint 6, 3, 7 on the top of a magnetic shield casing 1 containing the other electrical components of the oscilloscope so that the screen of the tube may be viewed from any desired angle. The shield 11 fits into a hole in the ball 6 which is retained by the part-spherical seating formed by the inside surfaces of the rigidly interconnected annular members 3 and 7, and the member 3 is supported at an angle by the circular aperture of a curved extension 2 of the casing 1. The supply leads for the tube extend from the tube socket 13 through the ball 7 to terminals 14 on an insulated plate 15. The shield 11 projects at 12 beyond the screen of the tube 5 to form a light shield.
