Henry J. Nolte Papers, 1915-1960.

The Henry J. Nolte Papers, 1915-1960, contain student and professional papers documenting Nolte's education at RPI, and aspects of his work at General Electric Company on Vacuum tube development, and ceramic- and glass-to-metal seals.

The student papers, 1917 and undated, are arranged alphabetically be subject. They contain notes, exercises, and labs in such courses as calculus, german, electricity, and physics. The physics notes (box 1 folders 3-4) also contain notes on quantitative analysis and inorganic chemistry.

The professional papers, 1915-1960, contain a set of laboratory notebooks, project files, materials regarding patents, and a collection of symposia proceedings and reports. The laboratory notebooks, 1915-1940, arranged chronologically, provide notes on Nolte's daily or weekly activities at General Electric Company, notes on experiments, data, and figures. The project files 1919-1957, arranged alphabetically, represent only a small portion of Nolte's work. Files contain a variety of internal and published reports, notes, correspondence, curves, figures, plans, data, financial information, etc. documenting Nolte's development of a high power pilotron and a metal vacuum tube, his studies of the properties of glass, ceramics, and metals, ceramic- and glass-to-metal seals and development of a dry hydrogen brazing furnace. The patents files includes correspondence and figures regarding Nolte's work on metal-to-ceramic seals, evacuation by internal getter, and a bracket for attaching a can to a ladder. The reports, primarily General Electric Company Research Laboratory reports, include papers on German Vacuum tube techniques (1945), ceramic-to-metal seals, etc.
