Patent number: 7896726Abstract: A method and apparatus for removing a coating having an irregular surface configuration that includes mapping the irregular surface configuration, and using the mapping determination in controlling the operation of an abrasive water jet to provide increased material removal rates at the higher points in the irregular surface and decreased material removal rates at the lower points, and thereby even out the surface configuration of the coating. The method and apparatus also includes using a detection device for detecting the presence or absence of an element that is unique to a layer of a coating, and using the detection determination in controlling the operation of the abrasive water jet to stop material removal of the coating when the detection device determines there is an absence of the unique element.Type: GrantFiled: March 19, 2009Date of Patent: March 1, 2011Assignee: Huffman CorporationInventors: Mitchell O.

Patent number: 7104385Abstract: A system unloads material, such as bulk quantities of dry product, from a container, such as a railroad hopper car, in a fast and efficient manner. The container defines an interior adapted to contain a product and includes a product discharge section adapted to allow the product to pass therethrough. The material unloading system includes a product outlet line adapted to communicate with the product discharge section. The product outlet line includes a product outlet adapted to allow the product to pass therethrough. A source of pressurized fluid communicates with the product outlet line and is adapted to move product from the product discharge section to the product outlet. A source of vacuum communicates with the product outlet and is adapted to unload the product from the product outlet.Type: GrantFiled: July 20, 2001Date of Patent: September 12, 2006Inventor: William R. Pearson

Patent number: 6911886Abstract: A flux coil system has a first member having a first surface and a first flux coil being disposed in the first member. The flux coil has a first current flowing conduit having a second surface. When current traverses through the first current flowing conduit a first magnetic field is induced. The first surface is adjacent to the second surface such that the first flux coil is in the first magnetic field so that a signal is developed corresponding to the first magnetic field.Type: GrantFiled: August 8, 2003Date of Patent: June 28, 2005Assignee: General Electric CompanyInventors: William R. Pearson, Jordan Brantley Casteel, Douglas G. Fowley

Patent number: 6294898Abstract: A method and apparatus for compensating, consistent with variations in cooling conditions, protection and limit functions of a generator. Limits of the capability curve of the generator, including the overexcited region, underexcited region and region limited by stator current heating, are modified in response to changes in coolant pressure or temperature depending on the type of generator being compensated. Feedback signals and setpoints being provided to fixed protection and limit functions are intercepted and modified in accordance with the relationship between generator rated values and generator performance in view of altered coolant conditions. Protection and limit functions are automatically coordinated. As a result, overall generator performance is improved.Type: GrantFiled: January 16, 2001Date of Patent: September 25, 2001Assignee: General Electric CompanyInventors: Rodney A. Lawson, William R. Pearson, James E. Curran

Patent number: 5364363Abstract: A rectal administrator comprises a body having an administrative portion adapted to be inserted into a subject's rectum. A charge of medicament is disposed within the body, and the administrative portion has at least one passage through which the medicament can exit the body. A plunger is disposed in the body and is movable from a first position to a second position within the body to dispense the medicament from the body through the at least one passage. A releasable energy source is mounted within the body so as to be released in response to a predetermined actuating procedure.
