Abstract : Efforts concerned an evaluation of the application of polyoptic sealing to hydrogen thyratron production techniques and the investigation of other means of protective sealing. A number of various polishing and sealing techniques were investigated and compared. Various means of sealing methods were attempted: The hot ring localized heating technique; The intermediate material technique, which includes glass solder, enamels, cements, and metals; True polyoptic sealing, in which a near perfect fit of button to bulb permits a seal to be made by intermolecular migration; The ultrasonic welding technique. The hot ring technique of all the methods under investigation proved to be the most satisfactory and practical means for making seals. The sealing and processing of polyoptic tubes was carried out on both automatic and trolley exhaust equipment. Best results were obtained by sealing and processing on trolly exhaust. (Author)
