Abstract (en)
Getter assembly for a cathode ray television picture tube which minimizes arcing currents within the tube. The getter assembly comprises a metal receptacle (40) with an annular channel (44) in its floor member (50), the side wall (48) of the receptacle (40) being relatively higher than the elevated centre portion (42) of the floor member (50) circumscribed by that channel (44), a wire support member (60) depending from the receptacle (40) for contacting the inside wall (20) of a cathode ray tube and having its ends (64, 68) located beneath that floor member (50) inwardly from that side wall (48). When the getter material (46) tained in the channel (44) is flushed it will not be deposited in the shade area beneath the receptacle where the support member (60) contacts the inside resistive coating thus preventing short circuitry between the getter assembly and the getter material deposit.
