Patent number: 7022910Abstract: In one aspect, the invention provides photovoltaic cells that utilize a mesh electrode on at least one exposure side of the photovoltaic cell. Preferably, the mesh electrode is a metallic mesh. In one embodiment, the invention provides dye-sensitized solar cells (DSSC) having a wire mesh exposure side electrode and a photovoltaic material comprising a photosensitized interconnected nanoparticle layer. In one embodiment, the wire mesh electrode functions as the cathode of the DSSC. In another embodiment, the wire mesh electrode functions as the anode of the DSSC. In addition, embodiments are provided where wire mesh electrodes are used for the anode and the cathode of a DSSC.Type: GrantFiled: March 24, 2003Date of Patent: April 4, 2006Assignee: Konarka Technologies, Inc.Inventors: Russell A.

Patent number: 5756253Abstract: There are described novel photographic processing compositions, film units and processes for use in diffusion transfer photographic systems. More particularly, there is described a method for forming a diffusion transfer image photographic processing of diffusion transfer photographic film units in the presence of hypoxanthine and inosine. Diffusion transfer photographic systems utilizing the novel photographic element or method of the present invention exhibit substantially fewer, if any, crystals on the final image of the finished photograph post-processing.Type: GrantFiled: July 9, 1997Date of Patent: May 26, 1998Assignee: Polaroid CorporationInventors: Robert D. Eckert, Michael P. Filosa, Gerard Gomes, Anthony R. Layne, Marlene C. Schwarz, Lloyd D. Taylor

Patent number: 5422233Abstract: Photographic processing compositions comprising an aqueous alkaline medium and a hydrophobically modified thickening agent are disclosed. The subject thickening agent increases the viscosity of the processing composition while maintaining a relatively uniform homogenous mixture of the constituents thereof. The subject processing compositions are useful in photographic diffusion transfer film units and processes.Type: GrantFiled: May 17, 1994Date of Patent: June 6, 1995Assignee: Polaroid CorporationInventors: Robert D. Eckert, Daniel D. Huang, Francis M. Pierce

Patent number: 4726570Abstract: A ladle of the type having a bottom wall, sidewall and opposite trunnions extending outwardly from an upper portion of the sidewall is provided with a refractory lining by positioning a mandrel inside of the ladle in spaced relationship to the walls thereof to define a castable space. The mandrel is attached to an elongated horizontal support which extends over the top of the ladle. The elongated horizontal support is supported by the ladle trunnions and is also locked thereto against upward displacement. At least a portion of the mandrel which cooperates with the ladle sidewall is expandable and collapsible toward and away from the ladle sidewall. After the castable space is filled with castable refractory material, such material is allowed to solidify, and the elongated horizontal support is released from the trunnions so that the support and mandrel attached thereto can be lifted upwardly.Type: GrantFiled: January 7, 1987Date of Patent: February 23, 1988Assignee: North American Refractories CompanyInventors: Robert H. Phillips, Robert D. Eckert, Alan L. Fisch, Glen H. Mead, III

Patent number: 4418139Abstract: Solid compositions are disclosed comprising a complex of water; a benzotriazole of the formula ##STR1## wherein R.sup.1 and R.sup.2 are independently hydrogen, a monovalent organic radical, halogen, or nitro; and at least one water-soluble base having a basicity greater than that of the benzotriazole and capable of dissociating to provide an anion and a monovalent or divalent metal cation. The compositions have melting ranges above 35.degree. C. and are capable of releasing a substantial portion of the water contained therein to the surrounding environment when melted. The compositions can be employed in thermally developable photographic film units as thermally induced water-releasing materials which provide water to the internal environment of the film unit when the film unit is heated sufficiently to melt the composition.Type: GrantFiled: September 30, 1982Date of Patent: November 29, 1983Assignee: Polaroid CorporationInventors: Howard G. Rogers, Robert D. Eckert, Ronald A. Sahatjian, Robert A. Sulesky
