摘要:
An apparatus comprising a cartridge loop, the cartridge loop having a coupling interface with an opening defined in part by a pair of substantially parallel lines separated by a distance; and a coupling comprising first and second ends and a link that connects the first and second ends, the first end connecting with the coupling interface of the cartridge loop wherein a portion of the link adjacent the first end has a first thickness that is greater than the distance between the substantially parallel lines and a second thickness that is less than the distance between the substantially parallel lines.

A pressure discharge valve for storage tanks on land or trucks including a valve body having a through hole therein adapted to mate and communicate with a through hole in a wall of the storage tank, a first vent means comprised of a eutectic composition which automatically provides a partial release of storage tank liquid at a first predetermined temperature lower than critical combustion and/or explosive temperatures of liquid in the storage tank, to provide a visual signal and warning to firefighters of these hazardous conditions, and a second vent means comprised of a eutectic composition to automatically vent liquid in the storage tank through the hole in the valve body when the liquids therein reach a predetermined critical temperature. In addition, the pressure discharge valve preferably comprises a eutectic solder material disposed between the valve body and the second vent means, which changes phase (i.e., reaches its eutectic point) below the eutectic point of the second vent means, thereby providing a lubricant between the plug and the valve body.

Methods of making a hybrid crude oil using man-made or natural petroleum-based waste stream products. The hybrid crude oil is composed of an oil-based solution and petroleum-based coatings that were extracted from a petroleum-containing material. This hybrid crude oil is created by elevating the temperature of the oil-based solution to or above an elevated temperature, i.e., the melting or phase-change temperature of the petroleum-based coating so that it can become liquified and dissolve into the oil-based solution and create the hybrid crude oil. The petroleum-containing material is submerged into the heated oil-based solution to cause the petroleum-based coatings to dissolve into the heated oil-based solution at the elevated temperature. The liquid oil-based solution at the elevated temperature creates an environmental seal to the petroleum-based coatings to protect them from burning, carburizing, or degrading, until the liquid oil-based solution is capable of providing the necessary thermal energy for the phase change of the petroleum-based coating from a solid state to a liquid state. At which time, the petroleum-based coatings safely phase-changes into a liquid and dissolves into the oil-based solution, creating the hybrid crude oil.

摘要:
A method to reclaim or recycle asphalt or asphalt components to produce reusable asphalt or asphalt components featuring (a) providing crushed asphalt or asphalt components, and (b) adding the asphalt or asphalt components to a solvent in which the asphalt binder is soluble. The solvent may be at approximately ambient temperature and may be, for instance, heptane, hexane, naphta, kerosene, gasoline or a petroleum based solvent or any other suitable solvent in which the asphalt binder is soluble. The solvent may be added in a standard automated parts washer or equivalent equipment to provide exposure to one or more solvents in which the asphalt binder is soluble. The method may further feature c) grinding or breaking the asphalt to be reclaimed or recycled into chunks, millings or particulate prior to step a), d) screening or separating coarse aggregate and fine aggregate asphalt components from the solution of b), d) cleaning or removing asphalt binder and/or the solution from the coarse aggregate and fine aggregate asphalt components screened or separated in step c), and e) cleaning or removing asphalt binder from the solution of b).
摘要:
A detonator formed entirely from a plurality of discrete segments of an insensitive energetic composition, each of the segments employed in the detonator being compacted at different pressures from powder and/or granules of insensitive energetic composition so as to form an energetic train which sequences detonation of the individual segments. Initiation of a main charge can only be effected when a last segment in the detonation train is initiated. Detonation starts with a first segment in the detonation train which is produced under the lowest compaction pressure, and then detonation progresses to a last segment compacted under a higher compaction pressure. The first segment can be detonated by a safety fuse or detonating cord, and the last segment can only be detonated by the next to the last segment in the detonation train.

摘要:
A method is disclosed for the retrieval and recovery of organic-based or organic-containing materials, including naturally occurring substances such as crude oil, and other petroleum-based or containing materials, natural gas, and the like, from environments where they are entrained within or otherwise admixed or complexed with other organic or inorganic materials, such as rock, sand, shale and the like. The method comprises: (a) retrieving a quantity of the petroleum-containing mixture, (b) treating the petroleum-containing mixture with a solvent for the petroleum material to separate the petroleum material from the mixture and (c) recovering the petroleum-containing material separated in step (b). The method also includes the reclamation or recycling of asphalt or asphalt components to produce reusable asphalt or asphalt components featuring (a) providing crushed asphalt or asphalt components, and (b) adding the asphalt or asphalt components to a solvent in which the asphalt binder is soluble. The solvent may be at approximately ambient temperature and may be, for instance, heptane, hexane, naphtha, kerosene, gasoline or a petroleum based solvent or any other suitable solvent in which the asphalt binder is soluble.
