The composite film consists of a thin film layer and a backing layer. The backing layer is soluble in a solvent in which the thin film layer is not soluble. In accordance with the method, the composite film is installed in a device in the same position in which it is sought to finally emplace the thin film. The backing layer is then selectively dissolved in the solvent to leave the insoluble thin film layer as an unbacked film. The method permits a very thin film to be successfully installed in devices where the fragility of the film would preclude handling and installation by conventional methods.Type: GrantFiled: April 26, 1982Date of Patent: May 15, 1984Assignee: The United States of America as represented by the United States Department of EnergyInventors: David V.

Patent number: 4436715Abstract: This invention relates to production of singlet oxygen and includes means and methods for storage and retrieval thereof as well as continuous production from ground state oxygen. With respect to storage and retrieval of singlet oxygen, certain aromatic acceptor compounds are oxidized to yield solid endoperoxides which, in turn, are decomposed to yield singlet oxygen and regenerate the acceptor. Continuous production of singlet oxygen occurs through irradiation of dye sensitizers with electromagnetic radiation causing activation thereof and excitation of flowing ground state oxygen.Type: GrantFiled: September 14, 1981Date of Patent: March 13, 1984Assignee: KMS Fusion, Inc.Inventors: A. Paul Schaap, George E. Busch, Robert L. Nolen, Jr.
