Patent number: 6371323Abstract: An improved double wall tank has two or more threaded fittings, with a steel outer tank and a thermoplastic inner tank. The inner tank is formed within the outer tank by rotational molding. The inner tank is bonded to the outer tank in an area of the fittings, but is otherwise separate and apart from the outer tank. Before carrying out the rotational molding process, bonding material is applied to the outer tank in the area of the fittings. The thermoplastic material is in powder form and includes mold release material. The thermoplastic material is inserted into the outer tank before rotational molding. The degree of shrinkage of the inner tank can be controlled by air pressure including an area between the fittings.Type: GrantFiled: December 15, 1998Date of Patent: April 16, 2002Assignee: Clemmer Technologies Inc.Inventor: Elson G. Fernandes

Publication number: 20020008112Abstract: A storage tank for fluids comprises a novel striker plate. The striker plate is comprised of a sacrificial galvanic anode and a steel core, and it is situated opposite an access opening used for measuring depth of fluid in the tank. The striker plate can also function adjacent other corrosive areas in a tank, such as along a seam in a tank wall, to reduce corrosion.Type: ApplicationFiled: May 15, 2001Publication date: January 24, 2002Inventors: James B. Bushman, Brian C. Donovan

Patent number: 6330767Abstract: An apparatus for efficiently removing grain from a grain storage device, which uses a plurality of augers. An unloading auger is used to begin removal of grain from a grain storage device. As the amount of grain decreases, a proximity sensor sends an activation signal to a cross auger that rests horizontally on the bottom of the grain storage device. The cross auger will pull the remaining grain to the entry point of an unloading auger. The unloading auger then removes the grain from the grain storage device.Type: GrantFiled: November 18, 1999Date of Patent: December 18, 2001Assignee: Gary W. Clem, Inc.Inventors: Brian W. Carr, Donald F. Handorf, Scott Sporrer, Ryan D. Jensen, Nick Merfeld, Mark D. Mathis

Patent number: 6318581Abstract: A discharge outlet is provided for attachment to a double wall containment tank assembly having an inner tank and an outer containment vessel. The discharge outlet includes a conduit fluidically connected to the fluid receiving chamber of the inner tank and extending exteriorly of the outer containment vessel, a flexible annular sealing member positioned between the inner tank and the outer containment vessel, and couplers for attaching the sealing member to the inner tank and the outer vessel in surrounding relationship to the conduit. The containment area between the two tanks which is designed fro containing spills from the inner tank is thereby fluidically isolated form the access opening through which the conduit passes.Type: GrantFiled: March 6, 2000Date of Patent: November 20, 2001Assignee: Snyder Industries, Inc.Inventor: Darwin Garton

Patent number: 6290473Abstract: A fluid cooling device in the form of a modular unit has a motor which drives a ventilator wheel and a hydraulic pump which takes fluid from an oil reservoir and delivers it to a hydraulic work circuit. The circuit heats the fluid and sends it to a heat exchanger from which the fluid returns, cooled, to the oil reservoir. The oil reservoir, being shaped like a trough and surrounding at least part of the motor and the hydraulic pump and having high walls in the manner of a half-shell, results in a relatively high-volume oil reservoir with is a part of the fluid cooling device with a compact, space-saving structure by at least partially containing parts of the fluid cooling device to save space.Type: GrantFiled: August 31, 1999Date of Patent: September 18, 2001Assignee: Flutec Fluidtechnische Gerate GmbHInventors: Lothar Thome, Wolfgang Schabbach

Patent number: 6286707Abstract: A container for the above-ground storage of flammable fuels has an inner tank which may be rectangular, with a bottom surface, side surfaces, and a top surface, or which may be some other shape, such as cylindrical, placed within an outer shell having a similar shape. In the case of a rectangular inner tank and a rectangular outer shell, the bottom surfaces of the inner tank and outer shell are spaced apart from each other by first bottom spacers which connect the two bottom surfaces. The side walls of the inner tank and outer shell are also spaced apart from each other by second side spacers which connect the tank and shell. The side spacers for connecting the tank and shell prevent the inner tank from floating within the outer shell when an insulating material, such as concrete, is added therebetween. The inner tank may be constructed of metal, fiberglass, fiberglass-coated metal, polyethylene, or other like materials, while the outer shell is steel.Type: GrantFiled: September 30, 1994Date of Patent: September 11, 2001Inventors: William Y. Hall, William A. Hall
