  • Publication number: 20240079929
    Abstract: 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.

  • Patent number: 8325454
    Abstract: An over heating detection circuit and an interrupter circuit are disclosed for interrupting electrical power from a power source receptacle to a load upon the detection of an over heating condition of an electrical plug. A heat sensitive device monitors the temperature of the electrical plug. The over heating detection circuit is connected to the heat sensitive device for detecting an over heated condition in the electrical plug. The interruption circuit includes a disconnect switch connected to the over heating detection circuit for disconnecting electrical power upon the detection of the over heated condition in the electrical plug.

  • Patent number: 8064174
    Abstract: 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.

  • Patent number: 7751161
    Abstract: A circuit is disclosed for disconnecting a power source upon the detection of a leakage. The circuit comprises a disconnect switch for disconnecting the power source. A primary circuit controls the disconnect switch. A secondary circuit senses a leakage current. An optical switch interconnects the primary circuit and the secondary circuit for opening the disconnect switch upon the secondary circuit sensing a leakage current. The circuit is suitable for use as a leakage current detection and interruption circuit for completely electrically disconnecting and isolating the power source and the primary circuit from the secondary circuit.

  • Patent number: 5606169
    Abstract: This invention relates to a retrofit apparatus utilized in Ultraviolet (UV) light sterilization equipment for paperboard packaging filling machines. Such structures of this type, generally, allow conventional paperboard packaging filling machines to be economically converted to include an ultraviolet light sterilization retrofit assembly wherein microbiological spoilage of the food product contained within the paperboard packaging can be significantly reduced.

  • Patent number: 4957578
    Abstract: 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.
