  • Color display tube and suspension means for color selection electrode
    Patent number: 4387321
    Abstract: A color selection electrode (7) is suspended from the corners of the upright edge (3) of a display window (2) by means of resilient elements (25) which extend substantially perpendicularly to the electron beams deflected towards the corners. The resilient elements (25) have apertures (28) with which the resilient elements (25) are placed on mandrils (31). The mandrils (31) are embedded in the corners of the upright edge (3) of the display window (2) perpendicularly to the planes of the resilient elements (25). A screening cap for screening the electron beams from the earth's magnetic field is connected on the mandrils (31) in such manner that the screening cap exerts no pressure on the resilient elements (25).

  • Color tube shadow mask mount
    Patent number: 4358702
    Abstract: A color selection electrode (7) is suspended in the corners of the upright edge (3) of the display window (2) by means of strip-shaped resilient elements (25) which extend substantially perpendicularly to the electron beams deflected towards the respective corner of the display window. The resilient elements (25), at their ends remote from the color selection electrode (7), comprise a peg (27) the axis of which extends substantially parallel to the direction of the electron beams directed towards the respective corner. In the corner of the upright edge (3) of the display window (2) a supporting element (30) is connected which comprises a portion (32) which is provided with an aperture (33), which portion (32) extends substantially perpendicularly to the axis of the peg (27). The pegs (27) fall partly through the apertures (33).
