Patent number: 5528044Abstract: A wiper is provided for cleaning reactor tubes used in an ultraviolet-light reactor. The wiper has a circular opening sufficiently large to resiliently accommodate a reactor tube. A plurality of wipers can be connected to a wiper support to create a wiper assembly. A rod attached to the wiper assembly, or a wiper, can be moved from outside the reactor chamber for mechanically reciprocating the wiper assembly along the length of the reactor tube in the chamber, whereby, the wiper slides along the outer surface of the reactor tube to wipe off at least some of the fouling that may have accumulated on the outer surface of the reactor tube.Type: GrantFiled: April 28, 1995Date of Patent: June 18, 1996Assignee: Solar Kinetics, Inc.Inventor: Joseph A.

Patent number: 5440131Abstract: A wiper assembly is provided for cleaning the reactor tubes of an ultraviolet-light reactor. The wiper assembly is positioned inside a reactor chamber of the ultraviolet-light reactor. The wiper assembly includes a wiper that has a circular opening sufficiently large to accommodate a reactor tube. A wiper blade is formed on the wiper circumferential of the opening and being deflected such that when the reactor tube is positioned through the opening, the blade engages the outer surface of the reactor tube. The wiper is formed of a plastic material. The wiper is connected to a platform positioned within the reactor chamber. The platform supports the wiper in the reactor chamber such that the reactor tube extends through the opening in the wiper. According to one aspect of the invention, at least one rod is connected to the platform. The rod extends out of the reactor chamber.Type: GrantFiled: July 21, 1994Date of Patent: August 8, 1995Assignee: Solar Kinetics Inc.Inventors: Joseph A. Hutchison, Paul T. Schertz

Patent number: 5237337Abstract: The present invention provides a method and apparatus for manufacturing at a manufacturing plant concave metallic membrane for concave reflectors such as solar energy collectors and antennas, rolling the concave metallic membrane onto a uniquely shaped mandrel for storage and transportation, transporting the rolled metallic membrane and mandrel to a site which is remote from the manufacturing plant, erecting a reflector support structure at the remote site, and attaching the concave metallic membrane to the reflector support structure. The invention includes a method for forming the concave metallic membrane into a paraboloid-like shape using non-uniform loading.Type: GrantFiled: January 18, 1991Date of Patent: August 17, 1993Assignee: Solar Kinetics, Inc.Inventors: Joseph A. Hutchison, Paul T. Schertz

Patent number: 5118540Abstract: Highly weather and corrosion resistant flexible reflective films for solar energy applications and lighting reflectors are formed by vapor-depositing silver onto a flexible support sheet, e.g., biaxially oriented polyester film and adherently bonding a protective fluorocarbon film, e.g., poly(vinyl fluoride), poly(vinylidine fluoride), or poly(tetrafluoroethylene), to the surface of the silver distal to the flexible support sheet with a layer of adhesive. Fluorocarbon film is highly optically transmissive to visible, ultraviolet, and/or near infra-red light between about 300-2,500 nanometers, stable to ultraviolet light, impervious to moisture, non-hygroscopic, scratch resistant, and easy to keep clean. The adhesive is highly optically transmissive to light between about 300-2,500 nanometers and stable to ultraviolet light. Chemical corrosion inhibitors and UV absorbers incorporated into the flexible reflective film can increase its resistance to corrosion and degradation by ultraviolet light.Type: GrantFiled: April 23, 1990Date of Patent: June 2, 1992Assignee: Solar Kinetics, Inc.Inventor: Joseph A. Hutchison

Patent number: 4306540Abstract: A solar collector system of the type having a movable surface for receiving solar radiation having improved means for rotatably supporting the movable surface and for rotating the collector surface. A support axle for the collector includes a ball at one end which is carried within a cylindrical sleeve in the solar collector to support the weight of the collector. A torque transmitting arm comprising a flexible flat strip is connected at one end to the axle and at the other end to the collector surface. An improved rotational drive mechanism includes a first sprocket wheel carried on the axle and a second sprocket wheel supported on a support pylon with a drive chain engaging both sprockets. A double acting piston also supported by the pylon is coupled to the chain so that the chain may be driven by a hydraulic control system to rotate the collector surfaces as required.Type: GrantFiled: June 25, 1979Date of Patent: December 22, 1981Assignee: Solar Kinetics, Inc.Inventor: Joseph A.
