Abstract:

Modifications in the Receiving Tube Inline Exhaust Machine are described. Changes were made in the pre-heat and tip-off unit, the leak detection system, the induction heaters, and the ovens, to obtain significant imporvements in the performance of the machine. Life test experiments on the 6005 indicated that the outgassing characteristics of this tube impose a basic limitation of the residual gas level that may be attained by any practical process schedule. The degree of outgassing attainable within the present operating limits of the machine is controlled primarily by the complex desorption characteristics of the tube structure acting in combination with pumping restrictions due to the tubulation and micas. Variations in process parameter levels over a broad range seemed to have very little effect on the total amount of gas evolved. The life tests on the 6005 tubes indicated some improvement due to the Inline Exhaust process, but the results were not as encouraging as had been expected. Also a description of process experiments and life tests on subminiature tube Type 5902 is included. Author
