A welding apparatus for welding a washer to a frame retaining spring while the washer and the spring are in engagement with a stud affixed to the sidewall of a kinescope panel. A welding head is suspended by an articulated joint and by flexible straps whereby the welding head is free to pivot and to flex to assure engagement with the parts to be welded when the spring is out of alignment with the welding head.

Shadow mask washer/spring welding apparatus

The apparatus for applying a bead of sealing material to a sealing surface of various size cathode-ray tube funnels comprises two stations. Each station is automatically adaptable for receiving different size cathode-ray tube funnels and includes means for raising and lowering the funnel. Included is a carriage moveable between the two stations. The carriage has means for distributing a bead of sealing material and means for vertically locating the position of a tube funnel.

Apparatus for applying sealing material to a cathode-ray tube

Apparatus and method are provided for determining the deviation in mask-to-faceplate spacing from a desired spacing during cathode-ray tube construction. The apparatus utilizes the novel method which comprises the steps of sensing the position of the interior surface of a faceplate without a shadow mask being mounted adjacent the faceplate, mounting a shadow mask adjacent the faceplate and sensing the position of a side of the shadow mask opposite the faceplate. The difference in the two second positions minus the shadow mask thickness is the deviation in the desired mask-to-faceplate spacing.
