Patent number: 11946702Abstract: A nuclear reactor includes a heat exchanger that transfers thermal energy from a primary reactor coolant to a secondary coolant. The heat exchanger is formed with a hot flow channel, a cold flow channel, and a porous layer between the hot flow channel and the cold flow channel. The porous layer may be thermally insulative to reduce the efficiency of thermal energy transfer from the hot flow channel to the cold flow channel. The porous layer may have a control gas passed therethrough that can be tailored to control the thermal energy transfer through the porous layer. The control gas can be tested for leakage within the heat exchanger. The control gas may also be used to sequester fission or activation products.Type: GrantFiled: March 23, 2021Date of Patent: April 2, 2024Assignee: TERRAPOWER, LLCInventors: Joon Hyung Choi, Daniel Eichel, Mei He, Pavel Hejzlar, Mathieu G. Martin, Samuel J. Miller, James M. Vollmer

Publication number: 20210037802Abstract: A water movement system and method configured to eradicate and/or control mosquito or insect populations that lay eggs in treated, stagnant water environments. The system is comprised of a water pump configured to function in cooperation with an underwater insect attractant device. The insect attractant device is suitably constructed to generate carbon dioxide for attracting insects to a water extermination zone or trap. In one embodiment, the underwater insect attractant device contains organisms such as mycelia for generating the carbon dioxide. Insects are attracted by the carbon dioxide generation device to reproduce in the water extermination zone, using the treated water to lay eggs, and grow larvae and pupae for the subject insects. A solar-powered water pump device is configured to direct the flow of water from the water extermination zone toward filters of the water pump device to trap and kill insect progeny including eggs, larvae, and pupae.Type: ApplicationFiled: January 25, 2019Publication date: February 11, 2021Inventors: Nathaniel J.

Patent number: 10737410Abstract: A method of manufacturing a sealed circuit card assembly includes disposing a circuit card assembly within a volume defined by a housing and at least partially filling the volume with a curable liquid such that the curable liquid encapsulates at least a circuit card. The method may also include curing the curable liquid to form a potted circuit card assembly and, after at least partially filling the volume with the curable liquid and after curing the curable liquid, vacuum impregnating the potted circuit card assembly with a sealant to seal any exposed interfaces or cracks to form the sealed circuit card assembly. Accordingly, the sealed circuit card assembly may include a first cured material encapsulating the circuit card of the circuit card assembly and a second cured material disposed within, for example, a porosity of the first cured material.Type: GrantFiled: July 18, 2019Date of Patent: August 11, 2020Assignee: GOODRICH CORPORATIONInventors: Michael A.

Patent number: 7757682Abstract: A magazine assembly presents a pressure cartridge to a compressed gas powered device, such as a gun, wherein the magazine assembly has a cartridge support biased with respect to a magazine to urge the pressure cartridge to a short (or seated) position, wherein an interlock plate is biased to engage the cartridge support. The bias on the interlock plate is overcome during insertion of the magazine assembly into a magazine chamber, at which point the cartridge support moves relative to the magazine in response to a seated length of the pressure cartridge. The bias on the interlock plate then controls the positioning of the interlock plate to engage the cartridge support and retain the pressure cartridge relative to the magazine assembly. A lever connected to the gun then engages the magazine assembly to translate the magazine assembly relative to the gun and pierce the pressure cartridge.Type: GrantFiled: October 5, 2006Date of Patent: July 20, 2010Assignee: Crosman CorporationInventors: Eduard Kaminker, James M. Martin, David C. Snyder, Robert Reifsnyder
