Publication number: 20130082468Abstract: A load protection system for a turbine is provided. The turbine has a load floor representing a lowest allowable load the turbine generally operates above. The turbine supplies power to an electrical grid. The grid has a grid frequency where as the grid frequency increases the turbine sheds load. The load protection system includes a controller in communication with the turbine and the electrical grid. The controller has a memory for storing a commanded target turbine load. The commanded target turbine load is the load the turbine operates at the load floor. The controller includes control logic for sending a flag to a variable rate limiter and a commanded load control block. The variable rate limiter and the commanded load control block generally prevent the turbine from shedding load and operating below the load floor once the flag is received.Type: ApplicationFiled: October 4, 2011Publication date: April 4, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: John Dalton Warren, Jr., John Rogers Huey

Patent number: 8066053Abstract: Disclosed is a method for dislodging a mold from a casting formed within the mold. The mold may be removed from the casting by scoring the mold and applying a force sufficient to cause the mold to fracture and break into pieces. Additionally, the mold may be fractured by either explosive charges placed in the mold pack or by high energy pulsations directed at the mold. Once the mold is fractured and broken into various pieces it may then be dislodged from the casting.Type: GrantFiled: September 17, 2007Date of Patent: November 29, 2011Assignee: Consolidated Engineering Company, Inc.Inventors: James Lewis, Jr., Ian French, Volker Knobloch, Scott Crafton, Paul Crafton, James Garrett, John Dalton

Patent number: 6234212Abstract: A pile loop forming assembly for looms for reliably transferring yarn from one side of the lance to the other in order for the yarn to be wrapped around the lance to form a loop. The loops may be cut by a blade as the loops advance and ride over the blade edge. The loops are formed by yarns passing through reed fingers wherein lances move the yarn from one side of the reed finger to the other. The lances are attached to a bar, which moves linearly in alternate directions so as to wag the lances to either side of the reed space. A heald moves the yarn up or down to selectively engage or disengage from the lances. A guide formation on a portion of the reed space helps deflect the yarn from one side of the lance to the other. The reed can pivot between a beat-up position and a weft insert position. As the reed moves to the beat-up position it engages the newly formed pile loop on the lance and pushes it to the fell.Type: GrantFiled: May 26, 2000Date of Patent: May 22, 2001Assignee: Griffith Textile Machines, Ltd.Inventor: John Dalton Griffith

Patent number: 5928746Abstract: A method and apparatus for manufacturing a crack repair product, and a method of repairing a crack using the product are disclosed. The material is made by heating and softening a bulk sample of direct-fire crack sealer material. The softened material is then extruded into a strand having a predetermined diameter. An anti-adherent material such as a polyethylene film is then applied to the extruded material, and the material is drawn along its length to reduce the diameter of the material to a desired diameter. In order to repair a crack, a length of the material is selected and has a diameter corresponding to the crack width. The material is packed into and near the top of the crack, and is then melted to permanently seal and repair the crack.Type: GrantFiled: January 21, 1997Date of Patent: July 27, 1999Assignee: Dalton Enterprises, Inc.Inventors: Peter F. Dalton, John A. Dalton

Patent number: 5743306Abstract: A tuft carrier loading apparatus for loading individual tufts into tuft-retention sites spaced along an elongate tuft carrier which is guided for longitudinal movement along a path of travel having a plurality of individually selectively operable tuft forming devices. Each tuft forming device is operable to feed an individual tuft to a tuft-retention site on the carrier. The carrier moves along said path of travel intermittently through a series of successive positions where predefined tuft retention sites are moved temporarily into registry with each tuft forming devices. By controlling selection of the tuft forming devices, tufts are fed to selected sites while the carrier is located at each successive position.Type: GrantFiled: July 22, 1996Date of Patent: April 28, 1998Assignee: Ulster Carpet Mills (Holdings) LimitedInventors: Richard Donald Stewart, John Dalton Griffith
