Abstract

1,103,563. Sheet forming. HILGER & WATTS Ltd. 1 April, 1966 [2 April, 1965], No. 14084/65. Heading B5A. An analysis cell window is made by forming a circular blank of bi-axially oriented and heat set polyethylene terephthalate film between matching male and female dies at a temperature between 150‹ and 200‹ C. and a pressure of about 5000 p.s.i. The dies are designed so that they contact only the peripheral parts of the blank, the central part thereof not being reduced in thickness during the forming. The window thus formed is then subjected to an hydraulic stretching operation at a pressure of 3-5 times the design operating pressure to prevent creep during its use.
