TLDR
Suspension elements for the electrodes in a multibeam electron gun, especially for a color television picture tube, having a novel construction are provided which cause their associated electrodes to either rotate about their axes or to remain in position to compensate for convergence drift during the warm up phase of the tube's operation.Abstract:

Color television cathode ray tube gun mounting
TL;DR: In this paper, a color television picture tube in-line gun assembly is described, in which individual guns are secured together with the aid of fastening clamps which are constructed to progressively tilt the outermost guns relative to the center gun during heating up of the tube in a manner to compensate for skewing of the beam axis as a result of such heating.
Patent
Colour television display tube
TL;DR: In this paper, a color selection electrode for a color television display tube is suspended in the corners of the display window by means of suspension means including a flat resilient element (37), which is connected to the colour selection electrode (31) or to another element of the suspension means by a substantially punctiform connection.

Multiple electrode support members with low coefficient of expansion
TL;DR: An electron gun assembly for generating a plurality of converging electron beams with at least one control electrode is supported eccentrically relative to the tube axis by a supporting member having a coefficient of linear expansion lower than 80.10-7 /°C as mentioned in this paper.
