Patent number: 10641524Abstract: Thermochemical energy storage (TCES) for concentrating solar power (CSP) systems provides higher energy density than sensible energy storage systems. An ammonia-based TCES system dissociates endothermically into hydrogen and nitrogen. The stored energy is released when supercritical hydrogen and nitrogen react exothermically to synthesize ammonia. Prior ammonia synthesis systems are unable to produce temperatures consistent with modern power blocks requiring a working fluid, for example steam or carbon dioxide, to be heated to greater than 600° C., for example about 650° C. An ammonia synthesis system heats steam from, for example 350° C. to 650° C. under pressure of about 26 MPa. The hydrogen and nitrogen are preheated with a flow of supercritical fluid prior to the synthesis step to provide reaction rates sufficient to heat power block working fluid to the desired temperature.Type: GrantFiled: June 27, 2016Date of Patent: May 5, 2020Assignee: The Regents of the University of CaliforniaInventors: Adrienne Gail Lavine, Richard Edward Wirz, Hamarz Aryafar, Chen Chen, Keith Lovegrove

The excavation shield apparatus (10) comprises a longitudinal body (11) having a lateral perimeter wall (12) surrounding a longitudinal throughway (13) adapted to be placed substantially vertically within the hole. A bottom end (11a) of the longitudinal body (11) is placed below the ground level and a top end (11b) is placed in close proximity to the ground level. The longitudinal throughway (13) is of sufficient size to permit passage of a person therethrough and has sufficient strength to endure forces imposed by the surrounding soil without substantial deformation. One or more apertures (16a-16d) are situated in the lateral perimeter wall (12) approximately at the bottom end (11a) for receiving utility apparatus therethrough so that a worker can operate upon the utility apparatus within the longitudinal throughway (13).Type: GrantFiled: April 29, 1993Date of Patent: March 28, 1995Assignee: Gwinnett Enterprises, LimitedInventor: Charles H. Pate, Jr.

Patent number: 5265981Abstract: A liner assembly for a manhole comprises a multiple ply generally cylindrical tube. The outermost ply is adapted for being impregnated with material for rigidifying and bonding the outermost ply to a manhole. The innermost ply is adapted for being impregnated with a material for rigidifying the innermost ply so that the manhole becomes structurally reinforced. An impermeable ply is disposed between the innermost and outermost plies. The outermost, innermost, and impermeable plies are secured together so that the plies are maintained facially oriented. Each of the plies is cut along a first end of the tube for providing a fluid flow path when the assembly is installed in the manhole and an opposite end of the tube is fully opened.Type: GrantFiled: June 5, 1992Date of Patent: November 30, 1993Inventor: Ronald A. McNeil

Patent number: 5261766Abstract: Vertical bore holes are constructed for municipal sanitary landfills by drilling or otherwise excavating holes of large dimension to substantial depth, in virtually all known soil conditions however variable. They can be excavated well below the groundwater table, then lined with an impermeable or other permanent liner. This allows the landfill area to be much more efficiently used for the storage of various waste products. Solid organic waste other than cellulosics can be anaerobically fermented to methane and compost. A central core shaft is used as gas removal vent and conduit. After methane generation and removal the resulting compost is removed for use as soil nutrients. This system fully complies with the Environmental Protection Act and other regulations now in force in North America. Air, soil, groundwater, and surface water pollution and contamination are eliminated as all waste storage is contained within its own environment below natural grade.Type: GrantFiled: July 13, 1992Date of Patent: November 16, 1993Inventor: James S. Anderson

Patent number: 5197827Abstract: A method for lowering a basement structure includes forming several upright pile holes in the ground, providing each of the pile holes with a pile, providing several vertical guide holes and an excavation passage which are formed through the basement structure in such a manner that the guide holes are aligned with the pile holes, equipping each of the guide holes with an impelling device which is coupled with one of the piles, excavating soil below the basement structure, and activating the impelling devices to lower the basement structure into the ground in such a manner that the piles extend through the guide holes. Several vertical steel rods are embedded in each of the piles. Each of the impelling devices includes an upright cylinder body fixed on the top end of the basement structure, a piston rod extending through the cylinder body, and a piston carried on the piston rod. An internally threaded engaging member is engaged with the externally threaded lower portion of the piston rod.Type: GrantFiled: February 4, 1992Date of Patent: March 30, 1993Inventor: Yuan-Ho Lee

Patent number: 5176470Abstract: The lower end of an outwardly tight shaft structure (3) for a bore shaft (1) rests on a tilting joint arrangement (15, 20). This arrangement includes a hydraulic thrust bearing (15) at the end face of the shaft structure (3) and a hydraulic annular cylinder (20) at the circumference of the lower end of the shaft structure (3). Thus, this tilting joint arrangement (15, 20) is located between the shaft structure (3) and the base (10) and permits tilting of the shaft structure (3) relative to the ground (12) without impairing the water-tightness of the bore shaft foundation.Type: GrantFiled: June 13, 1991Date of Patent: January 5, 1993Assignee: Gewerkschaft Auguste VictoriaInventor: Hans-Otto Lutgendorf

Patent number: 5131789Abstract: A connector assembly for use in fastening two plate members together, particularly such members may be mill hole liner ring segments or mill hole liner rings which are fastened together to form a mill hole chute. The connector assembly is comprised of a connector tongue, connector clip and a wedge means. The connector clip is attached to a first plate member and extends outward perpendicularly from said plate member. The connector tongue is attached to a second plate member. In use the two plate members are aligned in edge to edge abutment so that the connector tongue is inserted through the aperture in the connector clip. A wedge means is then inserted through the aperture in the connector tongue. The wedge means is held in place by frictional forces between the wedge, the connector tongue and the connector clip. The wedge means is driven into the aperture causing the plate members to be connected and positioned in edge to edge alignment.Type: GrantFiled: October 25, 1990Date of Patent: July 21, 1992Assignee: Walter DiTullioInventor: Pertti T.

Patent number: 5026209Abstract: A containment casing (10) for a deep well/gravity pressure reactor vessel includes a plurality of casing sections (11) each having a wall portion (20) with corrugations (21). An inner liner (24) and an exterior liner (25) prevent grout material (13) from entering the corrugations (21) during installation. Additionally, inner liner (24) is capable of supporting the hanging weight of the casing sections (11), and yet is susceptible to failure due to stresses induced by thermal fluctuations. The corrugations (21) allow for thermal expansion without a buildup of compression stresses and further allow for angular deviations of the casing (10).Type: GrantFiled: August 4, 1989Date of Patent: June 25, 1991Assignee: Eau-Viron IncorporatedInventors: James A.

Patent number: 5022789Abstract: There are disclosed a method and a machine for constructing a shaft having a substantially circular cross-section. According to the present invention, the shaft having a shotcrete formed on a peripheral wall thereof can be easily constructed. The shotcrete can be promptly formed on the peripheral wall by spraying concrete on the wall above the water level of the water in the shaft before the wall is damaged. Also, muck excavated from a working face of the shaft can be efficiently conveyed therefrom to outside of the shaft even if the shaft has a depth of more than hundreds of meters.Type: GrantFiled: November 17, 1988Date of Patent: June 11, 1991Assignee: Shimizu Construction Co., Ltd.Inventors: Akira Miyazaki, Yuichi Kikuchi, Yoshiyuki Ohara, Tomosburo Fujinaga, Takashi Kawata, Fumitoshi Mizutani, Tsugio Hida, Shiroyasu Shimazaki
