Patent number: 8944413Abstract: A solar-powered boat winch suited for installation upon boat lifting structures such as those in a remote location. The solar powered boat winch includes an electric motorized winch, a solar cell, a rechargeable battery, a recharger, and mechanical mounts for attaching the solar powered boat winch to a boat lift structure. The solar cell collects sufficient solar energy and converts it into electricity that charges the rechargeable battery. The rechargeable battery acts as the power source for an electric motor of the winch. The winch assembly also includes remote controlled operation.Type: GrantFiled: March 15, 2013Date of Patent: February 3, 2015Inventors: Gary L. Hatch, James Hatch

Patent number: 7540955Abstract: A cartridge for a water treatment system, effective to assist in the removal of contaminants by photocatalytic oxidation and by adsorption, includes a plurality of stacked disks, preferably made of a UV light transmissive material, which disks define circuitous flow paths for water being treated. In a preferred embodiment, the disk surfaces contacted by the water are provided with a coating of a catalyst, such as TiO2, activated by a UV light source positioned in the center of the cartridge.Type: GrantFiled: April 7, 2006Date of Patent: June 2, 2009Assignees: Pentair Filtration, Inc., Wisconsin Alumni Research FoundationInventors: Gary L. Hatch, Michael D. Steinhardt, Michael J. Kurth, Marc A. Anderson

Publication number: 20030222013Abstract: A drinking water filter inhibits retrograde bacteria growth at the user outlet with the combination of a non-carbonaceous submicron filter element immediately upstream of the system outlet and a copper orifice element in the outlet downstream of the filter element. The copper orifice element preferably comprises a thin copper disc having a single orifice. The submicron filter element preferably comprises a hollow fiber bundle filter element.Type: ApplicationFiled: June 3, 2002Publication date: December 4, 2003Inventors: Vue X. Yang, Gary L. Hatch, Renaud Sublet

Patent number: 6117332Abstract: A feeder insert apparatus for a tubular water filtration cartridge utilized in household point of use water filtration systems. The feeder insert allows a chemical to be fed into a incoming water supply at a controlled rate by employing a bypass system that allows a predetermined amount of incoming water to flow past the feed chemical without contacting the chemical. The amount of water in the bypass flow can also be manually adjusted through the use of two adjustment mechanisms, an adjustable ring and a rotatable end cap, located on the feeder insert.Type: GrantFiled: January 18, 1999Date of Patent: September 12, 2000Assignee: Plymouth Products, Inc.Inventors: Gary L. Hatch, Bruce A. Stump

Patent number: 5928512Abstract: A small filter cartridge is particularly adapted to be attached to the neck of a conventional plastic soft drink bottle to filter contaminated water contained in the bottle by passing the water through the filter as it is discharged from the bottle. The flexible bottle walls are squeezed to pressurize the water and facilitate flow through the filter element. The filter includes a uniquely positioned check valve which allows pressure equalization of the bottle interior in a simple and efficient manner. The filter is attached directly to the neck of the bottle and embodiments are disclosed in which the element is inserted completely within the bottle and mounted entirely outside the bottle.Type: GrantFiled: April 3, 1996Date of Patent: July 27, 1999Assignee: Plymouth Products, Inc.Inventors: Gary L. Hatch, Robert S. Frank

Patent number: 5106501Abstract: A composite cartridge type filter of the kind utilizing a hollow cylindrical body of bonded activated carbon and an interior filled with a particulate filter media bed is disposed within a housing such that raw unfiltered water passes radially inwardly through the carbon body, into the interior media bed and then axially through the media bed to an outlet in one end. To balance the radial flow of water through the carbon body and maximize contact with the particulate media bed, a flow distribution device is disposed in the interface between the carbon body and the particulate filter media bed to distribute a portion of the flow toward the end of the media bed which is remote from the cartridge outlet. In this manner, short circuiting of the water through the filter is eliminated, radial flow through the carbon body is balanced, and a substantial portion of the flow is forced to follow a path which carries it through substantially the full length of the particulate media bed.Type: GrantFiled: September 23, 1991Date of Patent: April 21, 1992Assignee: Ametek, Inc.Inventors: Vue X. Yang, Gary L. Hatch, Thomas D. Holler

Patent number: 5061367Abstract: A filter cartridge for treating drinking water to remove a broad range of microorganisms includes a microbiocidal resin layer, a porous activated carbon filter element and a flow controller to assure a minimum effective residence time of water in the filter under varying pressure conditions. The microbiocidal resin preferably comprises a halogenated resin bed which is effective to kill a broad range of bacteria, viruses and protozoan cysts. The five micron carbon filter element removes any particularly resistant cysts which may have survived passage through the resin bed. The filter may also be provided with a scavenger resin downstream of the haogenated resin bed to remove any free halogens from the final effluent. A buffering resin may also be included upstream of the halogenated resin bed to precondition high pH supply water.Type: GrantFiled: October 13, 1989Date of Patent: October 29, 1991Assignee: Ametek, Inc.Inventors: Gary L. Hatch, Ralph A. Polasky

Patent number: 4190529Abstract: A strongly basic anion-exchange resin loaded with iodine and a less than stoichiometic amount of an iodide salt or bromine and a less than stoichiometric amount of bromide salt is an effective demand bactericide for disinfecting water. The bactericidal resin according to the invention elutes only small amounts of halide ions and is especially suited for killing bacteria in feed water supplies having relatively high salt content.Type: GrantFiled: February 2, 1979Date of Patent: February 26, 1980Assignee: Aqua-Chem, Inc.Inventor: Gary L.
