  • Patent number: 5241393
    Abstract: An improved cathode ray tube has a shrink-fit implosion protection band surrounding a portion of the tube envelope. The band includes a plurality of lugs for supporting the tube. The improvement comprises the band including a plurality of embossments arranged around the band. The embossments extend outwardly from the tube for a preselected distance to form cavities between the tube envelope and the embossments. The embossments include smooth outer surfaces to which the lugs are attached by welds. The embossments have indentations at the locations of the welds that extend into the cavities. The cavities have depths greater than the depths of penetration of the indentations into the cavities. By utilizing the embossments, the indentations, caused by welding, remain out of contact with the tube envelope.
