  • Implosion protection for TV tubes
    Patent number: 4245255
    Abstract: There has been provided a television tube having a funnel, panel, and neck portion fused together in a conventional manner. A circumferential implosion protection controlled surface discontinuity is formed in a rearward portion of the funnel for establishing a stress concentration location near a point of maximum stress therefor, such that in the event of a destructive impact to the panel, the tube will crack along the controlled surface discontinuity and reduce the implosion potential of the tube.
