Abstract: A reusable, portable campfire cover is disclosed herein. In its most basic configuration, the cover device (10) comprises three partial-conical panels, which are identified as a door panel (22), a first side panel (24), and a second side panel (26). Door panel (22) includes a handle (28). Each panel has a slot (30) and finger (32) feature in its base. Each panel has an aperture (34) or hole (36) near its top. The aperture (34) or hole (36) features are able to accept connectors, preferably an “S” hook connector (44). Cover device (10) is meant to be used in conjunction with a typical, independent tripod campfire device (20), which can be found in the prior art and in the consumer marketplace.

Abstract: Sodium nonatitanate compositions, a method using the composition for recovery of 82Sr from irradiated targets, and a method using the composition for generating 82Rb. The sodium nonatitanate materials of the invention are highly selective at separating strontium from solutions derived from the dissolution of irradiated target materials, thus reducing target processing times. The compositions also have a very low affinity for rubidium, making it an ideal material for use as a 82Rb generator. Sodium nonatitanate materials of this type both improve the recovery of 82Sr and provide a safer, more effective 82Rb generator system.

Abstract: Radioisotope generators comprising inorganic layered hydroxide composition, such as magnesium aluminates and lithium aluminates. These inorganic layered hydroxides form anion exchange materials that exhibit surprisingly high selective affinities for certain radioisotopes. Inorganic layered hydroxides have been prepared and shown to have high affinity for tungstate anions, the anion form of tungsten-188, yet low affinity for perrhenate anions, the anion form of rhenium-188.

Abstract: A cylinder head of an engine is disclosed, the cylinder head including an upper deck, a lower deck, and a sidewall extending between the upper deck and the lower deck. The lower deck defines a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion. An engine is also disclosed that includes a cylinder block having a cylinder bore, and a piston slidably positioned within the cylinder bore. The engine also includes a cylinder head having a lower deck connected to the cylinder block, the lower deck defining a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion by a recess.

Abstract: An engine that is operating with a combustible intake mixture may begin in to runaway, or in other words, uncontrollably operate at excessive speeds. In order to shutdown a runaway engine, the present disclosure determines whether an engine is operating in a runaway condition. If the engine is operating in the runaway condition, a compression inhibiting mechanism is moved from a first position in which compression ignition can occur within at least one combustion chamber and a second position in which compression ignition cannot occur within the at least one combustion chamber.

Abstract: Inorganic ion exchange materials for the separation of 90Y from 90Sr include chabazite, clinoptilolite, potassium pharmacosiderite, sodium titanosilicate and sodium nonatitanate. These materials are suitable for making a 90Y generator that contains 90Sr immobilized on an ion exchange column of the materials. The materials have a very high selectivity for 90Sr, a very low selectivity for 90Y, good radiation and thermal stability, low toxicity, fast reaction kinetics, and can be readily and reproducibly synthesized. A method is thus provided for eluting 90Y from the ion exchange material with an eluant solution. The eluant solution is preferably aqueous, preferably has a pH greater than about 5, and preferably includes a chelating agent. Preferred chelating agents include gluconic acid, oxalic acid, iminodiacetic acid, nitrilotriacetic acid, citric acid, and combinations thereof.
