Patent number: 4361644Abstract: The disclosed method relates to a method for recording flow boundary layers in liquid media by photochemical means. According to the invention, surfaces which can be developed in a plane and to which a photographic film sheet is cemented are exposed under steady-state conditions to the flow of a liquid medium containing a dissolved agent reacting with the photo gelatin layer. The liquid medium may contain agents furnishing HS-ions or agents capable of dissolving silver halide or reducing silver halide. If a photographic film sheet is used, the silver ions of which are reduced to silver, the flow exposure is performed with an agent having oxidizing and dissolving action. With the method disclosed, half-tone photograms of flow boundary layers in liquids can be recorded.Type: GrantFiled: February 20, 1981Date of Patent: November 30, 1982Assignee: Siemens AktiengesellschaftInventors: Gerd Urban, Heinrich Opitz, Gert Mages

Patent number: 4250249Abstract: For developing residual-moisture photographs according to the wet-film technique, a pre-treatment with a first solution of about 5% ethanolic NaOH is performed first at about 13.degree. C. After the alkali exchange, the exposed film passes through a bath at a bath temperature of 50.degree. C. with a hydroquinone-containing photographic developer. This "Two-bath wet developing method" takes place in daylight. The developed, fixed, rinsed and dried film can be evaluated directly.Type: GrantFiled: August 25, 1978Date of Patent: February 10, 1981Assignee: Siemens AktiengesellschaftInventor: Bernhard Montag

Patent number: 4192764Abstract: A method for depositing a metal on a surface is disclosed. The method comprises treating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal and a radiation-sensitive reducing agent for the salt to form a sensitized surface. The sensitized surface is exposed to a source of light radiation to reduce the metal salt to a reduced metal salt species. Either or both of the preceding sensitizing or radiation exposing steps is restricted to a selected pattern on the surface to form a catalytic real image capable of directly catalyzing the deposition of a metal thereon from an electroless metal deposition solution. The catalytic real image is treated with a stabilizer comprising (a) a reducing agent for the non-noble metal ions of said reducible salt, (b) a complexing agent and (c) an accelerator to at least stabilize the catalytic real image.Type: GrantFiled: October 16, 1978Date of Patent: March 11, 1980Assignee: Western Electric Company, Inc.Inventor: Bruce S. Madsen

Patent number: 4181750Abstract: A method of depositing a metal on a surface is disclosed. The method comprises coating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal. The coated surface is selectively treated to reduce the metal salt to metallic nuclei to form a catalytic pattern thereon capable of directly catalyzing the deposition of a metal on the nuclei from an electroless metal deposition solution. The selectively treated surface is then exposed to a stripping solution comprising an organic acid selected from (a) a carboxylic acid having a structural formula of ##STR1## where R is a member selected from the hydrogen radical, H, and an alkyl group having 1 to 3 carbon atoms, (b) citric acid and (c) a mixture of any of the foregoing acids, to essentially remove portions of the coated surface which have not been selectively treated.Type: GrantFiled: September 9, 1977Date of Patent: January 1, 1980Assignee: Western Electric Company, Inc.Inventors: William M.
