  • Method for assembling a thermally-set getter spring in a CRT
    Patent number: 4045849
    Abstract: A cathode-ray tube comprises a getter container supported on a metal spring which is attached to and extends from the electron-gun mount assembly. At least a portion of the spring consists of an alloy, such as 55-nitinol (an alloy of nickel and titanium), which can be thermally set to a first shape, then cold formed to a second shape, and then restores itself to the first shape upon being heated above a predetermined transition temperature. The method includes providing a spring which has been thermally set and then cold formed, attaching the container to the spring and the spring to the mount assembly, sealing the container and the mount assembly in the tube, and then heating the spring above the predetermined transition temperature.
