3. J.E. Lundstrom, Method for production casting of ultrathin polymer membranes, US Patent 3767737; (October 23, 1973) [Note 1: The thickness was controlled by observing the constructive interference pattern of light reflected off the film moving over a water surface. The feed of the casting solution was adjusted to produce a yellow film. Note 2: The calculated film thicknesses in Table 1 would have interference patterns outside the visible range of 400–700nm. Note 3: The new ultrathin membrane on a Celgard® support was incorporated into an existing oxygen enricher project. Within a few months, a system was installed to produce oxygen enriched air in a client׳s treatment room (for emphysema patients).]
