Abstract
A window assembly for transmitting light into and from a vessel containing a high pressure, high temperature, highly reactive environment includes a truncated conical window which is substantially transparent to radiation, a truncated conical metal seal which circumferentially engages the window, and a case to which the window and the seal are secured. To facilitate automatic cleaning of the window, the surface of the window which is exposed to the high-pressure environment is seated substantially flush with the high-pressure surface of the case. By initially seating the window assembly by means of mechanical pressing, then subjecting the window assembly to a series of successively higher transient combustion pressures, a window assembly can be fabricated which can withstand prolonged service in a harsh environment such as that encountered in a large caliber artillery cannon or equivalent scientific and industrial applications.
