ABSTRACT:
Electrical heating unit for tipping-off vacuum electron tubes comprises a cylindrical resistance heating coil, a cylindrical heat-shielding means within and spaced from the heating coil and a support plate adjacent one end of the coil permitting leads of a vacuum tube to be positioned within the heat-shielding means. The heat-shielding means comprises a unitary member having a hollow cylindrical body, an outwardly-extending flange at one end of the body, and an inwardly-extending flange at the other end of said body adapted to support the leads of said vacuum tube with the tubulation of the tube extending therethrough. The body has a height that is less than the height of the longest lead of the vacuum tube.
