Patent number: 9505977Abstract: A gadolinium (Gd) loaded scintillation gel (Gd-ScintGel) compound allows for neutron and gamma-ray detection. The unique gel scintillator encompasses some of the best features of both liquid and solid scintillators, yet without many of the disadvantages associated therewith. Preferably, the gel scintillator is a water soluble Gd-DTPA compound and water soluble fluorophores such as: CdSe/ZnS (or ZnS) quantum dot (Q-dot) nanoparticles, coumarin derivatives 7-hydroxy-4-methylcoumarin, 7-hydroxy-4-methylcoumarin-3-acetic acid, 7-hydroxycoumarin-3-carboxylic acid, and Alexa Fluor 350 as well as a carbostyril compound, carbostyril 124 in a stable water-based gel, such as methylcellulose or polyacrylamide polymers. The Gd-loaded ScintGel allows for a homogenious distribution of the Gd-DTPA and the fluorophores, and yields clean fluorescent emission peaks. A moderator, such as deuterium or a water-based clear polymer, can be incorporated in the Gd-ScintGel.Type: GrantFiled: July 30, 2014Date of Patent: November 29, 2016Assignee: The United States of America Department of EnergyInventors: Catherine Lynn Riddle, Douglas William Akers, Ricky Lynn Demmer, Patricia Denise Paviet, Mark William Drigert

Patent number: 8878140Abstract: Apparatuses, methods, and systems relating to radiological characterization of environments are disclosed. Multi-detector probes with a plurality of detectors in a common housing may be used to substantially concurrently detect a plurality of different radiation activities and types. Multiple multi-detector probes may be used in a down-hole environment to substantially concurrently detect radioactive activity and contents of a buried waste container. Software may process, analyze, and integrate the data from the different multi-detector probes and the different detector types therein to provide source location and integrated analysis as to the source types and activity in the measured environment. Further, the integrated data may be used to compensate for differential density effects and the effects of radiation shielding materials within the volume being measured.Type: GrantFiled: October 29, 2009Date of Patent: November 4, 2014Assignee: Battelle Energy Alliance, LLCInventors: Douglas William Akers, Lyle Gene Roybal

Patent number: 8444191Abstract: A removable automobile molding has been developed that is an extruded plastic assembly, which attaches to the sides or fronts of the vehicle using a flexible magnetic film and can protect any surface of the automobile from dents or scratches. The flexible-plastic, guard assemblies are sized for each vehicle to allow car doors to be opened or closed with the assemblies attached and can be left on the vehicle either temporarily or permanently. Theft of the extruded plastic assemblies is prevented due to the use of spring-loaded clips attached to the extruded plastic assembly, which attach to the edges of the door and cannot be removed unless the door is open. For some vehicles the theft protection assembly may not be required or cannot be attached to the vehicle.Type: GrantFiled: March 25, 2011Date of Patent: May 21, 2013Inventors: Douglas William Akers, Ute Silvia Coggin

Publication number: 20110294083Abstract: A molten salt treatment system and process can include one or more tubular conduits flowably connected to a molten salt reactor, the tubular conduit containing concentrically within it a pipe or a shaft separated by an annular space therebetween, and one or more gas sources connected to feed gas into the annular space. The system may include a scrubbing device flowably connected to a molten salt reactor off-gas outlet to receive an off-gas, a first heating device configured to heat the effluent from the scrubbing device, and a filtering device flowably connected to receive the effluent from the heating device. An overflow conduit may be flowably connected to a molten salt reactor overflow outlet to receive molten salt therefrom and discharge the molten salt to a salt recovery vessel, and a blower or other gas mover may be connected to the molten salt reactor and the recovery vessel to prevent backflow of cold gases through the overflow outlet to the molten salt reactor.Type: ApplicationFiled: December 29, 2009Publication date: December 1, 2011Applicant: TATE & LYLE TECHNOLOGY LIMITEDInventors: James Edwin Wiley, William Akers, William R.

Patent number: 4573107Abstract: A steerable spotlight assembly characterized by a pair of spotlights rotatably coupled to a vehicle's front bumper, and a cable-and-gear arrangement which couples the spotlights to the vehicle's steering column. More specifically, the cable-and-gear arrangement includes a spotlight rotating mechanism attached to each of the spotlights, a split gear attached around the steering column, a pair of cable drive gears simultaneously engaged with the split steering column gear, and a pair of rotary cables coupled between the cable drive gears and the spotlight rotating mechanisms. The cable drive gears are spring loaded so that they may disengage from the steering column gear if the steerable spotlight assembly becomes jammed. The spotlight rotating mechanisms are sealed and supported so as to be resistant to environmental damage, and provided with a gearing system which will not permit rotational force to be transmitted back from the spotlights to the cables.Type: GrantFiled: October 1, 1984Date of Patent: February 25, 1986Inventors: David Stock, William Akers
