Publication number: 20240079929Abstract: A fluid moving apparatus includes an electric motor having a rotor and a stator and a propeller. The rotor rotates relative to the stator on an axis to generate a rotational output. The rotational output is provided to the propeller to power the marine propulsion apparatus. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the axis. A portion of a housing of the motor extends into the aquatic environment to facilitate heat dissipation.Type: ApplicationFiled: November 3, 2023Publication date: March 7, 2024Inventors: Thomas F. Janecek, Jeremy Scott Reynolds, Robert J. Lind, Timothy S. Roman, Tyler K. Williams

Patent number: 8064174Abstract: A circuit is disclosed for disconnecting a power source upon the detection of a leakage current comprising a power cable having an insulated first and a second wire. The power cable has a conductive shield surrounding the first and second wires with a drain wire electrically contacting the conductive shield. A disconnect switch is interposed between the power source and the power cable. A primary circuit controls the disconnect switch. A secondary circuit is connected to the drain wire for sensing a leakage current between the conductive shield and one of the first and second wires. An optical switch interconnects the primary circuit and the secondary circuit for opening the disconnect switch upon the secondary circuit sensing a leakage current.Type: GrantFiled: August 11, 2009Date of Patent: November 22, 2011Assignee: Technology Research CorporationInventors: Thomas S. Williams, Frank S. Brugner, Jr., Paul R. Gandolfi

Patent number: 4957578Abstract: A process is disclosed for preparing a high quality paperboard product with high brightness and a defect-free glossy surface. The product comprises a structure consisting essentially of a paperboard substrate onto one surface of which there is first applied a coating of a pigmented polyolefin and a subsequent coating of a clear polymeric material such as a polyester. The brightness and loss achieved for the paperboard product is superior to conventional coated paperboard, cast coated paperboard, or other laminated paperboards currently in use.Type: GrantFiled: March 22, 1989Date of Patent: September 18, 1990Assignee: Westvaco CorporationInventors: Todd H. Huffman, Debora F. Massouda, Thomas S. Williams, III
