  • Publication number: 20030198589
    Abstract: A method for producing halide brine wherein an alkali and a reducing agent are added to an aqueous fluid having a density greater than 8.30 lb/gal., (0.996 kg/L) water, waste water or sea water for example. The resulting fluid is then contacted with a halogen to form a halide brine. The reaction occurs in a conventional reactor such as a mixing tank.

  • Publication number: 20030126152
    Abstract: A computer-implemented export engine automatically extracts selected data directly from an object model via an object query language, automatically builds relational database tables for the extracted data and automatically inserts the extracted data into the tables. The tables with the inserted data are then loaded into a relational database.

  • Publication number: 20030059669
    Abstract: A vented-type leak-resistant motor cycle battery comprising a housing in which a plurality of cells are mounted, a battery cover sealed to an upper end of the housing in a liquid tight manner so that the battery cover overlies the cells each having a vent chamber, a filling hole and a filling plug and a vent chamber cover sealed to the battery cover in a liquid tight manner, the battery cover being provided with a vent line extending in a longitudinal direction of the battery cover in flow communication with the spaces above the cells and having an exit end tilted upwardly toward the outside and a vent cap assembly being fitted to the vent line at the tilted exit end.

  • Publication number: 20030017381
    Abstract: A leak resistant automotive battery comprising a housing containing cells having filling plugs; a battery cover sealed to an opened top end of the housing and having filling holes overlying the respective cells; at least one partition wall provided in the battery cover to divide the battery cover into at least two vent chambers, each vent chamber overlying a set of the cells, to prevent flow of electrolyte from one set of cells to an adjacent set of cells when the battery is tilted; a common vent line in the battery cover connecting the spaces above the cells in each set of cells, each of the common vent line being sealed at one end and connected at its other end through a vent chamber to one end of each of parallel vent lines having at its other end a vent cap assembly which permits escape of vented gases from the cells in each set.

  • Publication number: 20030013006
    Abstract: Leak retardant automotive battery comprising a housing for a plurality of cells housed therein and each having a filling plug and a battery cover provided onto the housing to overlie the cells and divided into two compartments by means of a central blockage, each compartment overlying a set of cells, each of vent lines connecting vent holes in the battery cover overlying each set of the cells so that the cells in each set are in communication with each other and being connected at its one end to the central blockage so as to isolate the two compartments; a vent cap assembly being provided at the other end of each of the vent lines for escape of vented gases.

  • Publication number: 20020130090
    Abstract: A method for regenerating a used halide fluid comprising a density greater than 9.0 lbs/gal. and containing both soluble and insoluble impurities. This method comprises the steps of (1) adding acid to the used halide fluid so that the pH is within a range of approximately 0 to 10.0; (2) contacting the used halide fluid with halogen to increase the density to at least 10.0 lbs./gal., adjust the desired true crystallization temperature of the fluid and oxidize soluble impurities; (3) adding a reducing agent while maintaining the temperature at a minimum of 10° C.; (4) contacting the fluid with an alkali to neutralize excess acid; and (5) separating any suspended solid impurities from the fluid.

  • Patent number: 6322811
    Abstract: Alkylene oxide polymer compositions having particular molecular weight distributions are disclosed. As a result of the molecular weight distributions, the disclosed alkylene oxide polymer compositions are suitable, among other things, for the manufacture of films, e.g., for use in manufacturing soft gel capsules. Capsules made from the disclosed alkylene oxide polymer compositions can provide enhanced resistance to crosslinking often caused by liquid filling materials, e.g., polyethylene glycol, used in gelatin capsule manufacture.

  • Patent number: 6304866
    Abstract: In a multiprocessing system, multiple concurrently operating task execution units are operated to perform an aggregate task by using incremental and on-demand sub-task allocation. A command is received to perform a machine-executed task divisible into multiple sub-tasks, i.e., an “aggregate task”. A granularity is then established, for dividing the aggregate task into sub-tasks. Preferably, the granularity is not too large to permit potentially uneven sub-task allocation, and not too small to incur excessive overhead in allocating sub-tasks. Having established the granularity, multiple task execution units are independently operated on-demand to sequentially self-allocate and execute sub-tasks of the aggregate tasks. Each sub-task is sized according to the established granularity. Operating “on-demand”, each task execution unit sequentially allocates and executes one sub-task at a time, then proceeding to the next unexecuted sub-task.

  • Patent number: 5561062
    Abstract: A new method of inactivating enveloped viruses and preparations useful in accomplishing this inactivation are disclosed. The method is based on the discovery that paucilamellar lipid vesicles, preferably having non-phospholipids as their primary structural material, can fuse with enveloped virus and that the nucleic acid of the virus denatures shortly after the fusion. The method is useful for inactivating viruses such as orthomyxoviruses, paramyxoviruses, coronaviruses, and retroviruses.

  • Patent number: 5490985
    Abstract: An antacid product having extended duration of residence in the gastric and upper intestinal systems has been developed. This antacid product includes a blend of 10-70% by volume nonphospholipid lipid vesicles, with a particulate base. An antiflatulence agent may also be included. A method of providing extended duration amelioration of acid build up in the gastric and upper intestinal tract using this product is also disclosed.
