Patent number: 4812237Abstract: A closed water purification and recycle system processes domestic wastewater to produce potable water for cooking, drinking and dishwashing and water suitable for general household use, such as washing clothes and personal hygiene. The system consists of septic tanks, a biological sand filter, an ultrafilter, a disinfection unit, pumps, valves, water quality and quantity sensors to monitor and control the process. The system also includes an incinerator toilet to eliminate the need for toilet flush water. Water for cooking, drinking and dishwashing is produced by a still using some of the recycled water for feed. The quality of the recycled water is monitored to assure the product water is suitable for the intended uses. Water thus produced is stored until reused. The system will be automatically shut down if the final product water quality does not meet specifications.Type: GrantFiled: December 21, 1987Date of Patent: March 14, 1989Assignee: Bio Tech, Inc.Inventors: William E. Cawley, Basil W. Mercer

Patent number: 4532102Abstract: A method and apparatus are described for the joint production and separation of tritium. Tritium is produced in an aqueous homogenous reactor and heat from the nuclear reaction is used to distill tritium from the lower isotopes of hydrogen.Type: GrantFiled: June 1, 1983Date of Patent: July 30, 1985Assignee: The United States of America as represented by the United States Department of EnergyInventor: William E. Cawley

Patent number: 4526741Abstract: A nuclear fuel assembly is described for producing tritium in a light water moderated reactor. The assembly consists of two intermeshing arrays of subassemblies. The first subassemblies comprise concentric annular elements of an outer containment tube, an annular target element, an annular fuel element, and an inner neutron spectrums shifting rod. The second subassemblies comprise an outer containment tube and an inner rod of either fuel, target, or neutron spectrum shifting neutral.Type: GrantFiled: June 10, 1983Date of Patent: July 2, 1985Assignee: The United States of America as represented by the United States Department of EnergyInventors: William E. Cawley, Turner J. Trapp

Patent number: 4511114Abstract: An electromechanical pipe snubbing system and an electromechanical pipe snubber. In the system, each pipe snubber, in a set of pipe snubbers, has an electromechanical mechanism to lock and unlock the snubber. A sensor, such as a seismometer, measures a quantity related to making a snubber locking or unlocking decision. A control device makes an electrical connection between a power supply and each snubber's electromechanical mechanism to simultaneously lock each snubber when the sensor measurement indicates a snubber locking condition. The control device breaks the connection to simultaneously unlock each snubber when the sensor measurement indicates a snubber unlocking condition. In the snubber, one end of the shaft slides within a bore in one end of a housing. The other end of the shaft is rotatably attached to a pipe; the other end of the housing is rotatively attached to a wall.Type: GrantFiled: January 18, 1982Date of Patent: April 16, 1985Assignee: The United States of America as represented by the United States Department of EnergyInventor: William E. Cawley

Patent number: 4475948Abstract: A composition is described useful in the production of tritium in a nuclear eactor. Lithium aluminate particles are dispersed in a matrix of zirconium. Tritium produced by the reactor of neutrons with the lithium are absorbed by the zirconium, thereby decreasing gas pressure within capsules carrying the material.Type: GrantFiled: April 26, 1983Date of Patent: October 9, 1984Assignee: The United States of America as represented by the Department of EnergyInventors: William E. Cawley, Turner J. Trapp

Patent number: 4322853Abstract: 1. In a nuclear reactor incorporating a plurality of columns of tubular fuel elements disposed in horizontal tubes in a mass of graphite wherein water flows through the tubes to cool the fuel elements, the improvement comprising at least one control column disposed in a horizontal tube including fewer fuel elements than in a normal column of fuel elements and tubular control elements disposed at both ends of said control column, and means for varying the horizontal displacement of the control column comprising a winch at the upstream end of the control column and a cable extending through the fuel and control elements and attached to the element at the downstream end of the column.Type: GrantFiled: August 27, 1963Date of Patent: March 30, 1982Assignee: The United States of America as represented by the United States Department of EnergyInventors: William E. Cawley, Robert F. Warnick

Patent number: 4307679Abstract: A submergible barge and process for submerging and storing radioactive waste material along a seabed. A submergible barge receives individual packages of radwaste within segregated cells. The cells are formed integrally within the barge, preferably surrounded by reinforced concrete. The cells are individually sealed by a concrete decking and by concrete hatch covers. Seawater may be vented into the cells for cooling, through an integral vent arrangement. The vent ducts may be attached to pumps when the barge is bouyant. The ducts are also arranged to promote passive ventilation of the cells when the barge is submerged. Packages of the radwaste are loaded into individual cells within the barge. The cells are then sealed and the barge is towed to the designated disposal-storage site. There, the individual cells are flooded and the barge will begin descent controlled by a powered submarine control device to the seabed storage site.Type: GrantFiled: December 21, 1979Date of Patent: December 29, 1981Assignee: The United States of America as represented by the United States Department of EnergyInventors: Fred L. Goldsberry, William E. Cawley

Patent number: 4006930Abstract: A device for gripping the interior of a tubular object to pull it out of a body in which it has become stuck includes an expandable rubber tube having a plurality of metal cables lodged in the exterior of the rubber tube so as to protrude slightly therefrom, means for inflating the tube and means for pulling the tube longitudinally of the tubular object.Type: GrantFiled: March 15, 1961Date of Patent: February 8, 1977Assignee: The United States of America as represented by the United States Energy Research and Developmnent AdministrationInventors: William E. Cawley, Charles E. Frantz

Patent number: H149Abstract: An on-line outlet temperature monitoring device to back up readings provided by stationary temperature detectors on individual process tubes in a nuclear reactor. The monitoring device includes a highly accurate temperature sensor that can be selectively coupled to the outlet end of any chosen process tube to verify temperature readings pertaining to that process tube. Specifically, the sensor is suspended in a movable enclosure that can be shifted into position about a supporting wall for the protruding ends of the process tubes. The movable sensor is used to back up readings provided by the stationary temperature detectors and to recalibrate the stationary temperature detectors so as to permit their use at lower tolerance limits.Type: GrantFiled: July 27, 1984Date of Patent: November 4, 1986Assignee: The United States of America as represented by the United States Department of EnergyInventor: William E. Cawley
