  • Patent number: 11975231
    Abstract: A forest fire retardant composition contains a retardant compound that includes a potassium salt. The potassium salt may include a potassium salt of an organic acid, a potassium salt of an inorganic acid, or mixtures thereof. The organic acid may include formic acid, acetic acid, propanoic acid, butanoic acid, lactic acid, oxalic acid, malic acid, gluconic acid, tartaric acid, uric acid, malic acid, or citric acid. The inorganic acid may include sulfuric acid, phosphoric acid, carbonic acid, or hydrochloric acid. The composition may be in the form of a dry concentrate, a liquid concentrate, or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.

  • Patent number: 7584086
    Abstract: The invention relates to numerical simulation of subsurface geological reservoirs. More specifically embodiments of the invention are related to computer modeling of the transmission of properties, for example the flow of fluids (e.g. hydrocarbon natural resources and water), within subsurface geological reservoirs. One embodiment of the invention includes a method of evaluating the transmission of a property within a subsurface geologic reservoir using a graph-theory single source shortest path algorithm.

  • Publication number: 20070276948
    Abstract: A system and method are described for automated configuration and deployment of applications. Each participant to a transaction maintains “connection parameters” which contain an indication of the various connection capabilities (protocols, file formats, document sequences, etc) of that participant. Prior to entering into a series of transactions (e.g., document exchanges), the connection parameters of two or more of the participants are compared to identify a common subset that are then exchanged between the participants until both participants agree on the connection parameters to use. The agreed upon connection parameters are stored within a “connection agreement” which is then used to automatically configure the applications (e.g., business collaboration applications) executed by each participant.

  • Patent number: 4206015
    Abstract: A method for simulation of lymphatic drainage using artificial capillary cell culture device having two separate perfusion circuits, and with the ultrafiltration fibers of the two circuits being woven into a single bundle. The present device provides a matrix for high density growth of cultured cells in a continuous perfusion system. The device is particularly well adapted for the use of pressure differences between perfusion circuits.
