  • Patent number: 7297324
    Abstract: Microchannel devices and method of use are disclosed wherein a reaction microchamber 52 is in thermal contact with a heat exchange channel 61. An equilibrium limited exothermic chemical process occurs in the reaction microchamber 52. Sufficient heat is transferred to the heat exchange channels to substantially lower the temperature in the reaction microchamber 52 down its length to substantially increase at least one performance parameter of the exothermic chemical process relative to isothermal operation. Optionally, an endothermic reaction occurs in the heat exchange channel 61 which is sustained by the exothermic chemical process occurring the exothermic reaction chamber. Both the reaction chamber 52 and the heat exchange channel 61 can be of micro dimension. Catalyst 75 can be provided in the microchamber 52 in sheet form such that reactants flow by the catalyst sheet.

  • Patent number: 6141892
    Abstract: An apparatus for limiting sliding wear and kick-back wear in straight sidebar chains as well as offset sidebar chains includes a wear bar which is attached to the outer surface of the chain's sidebar. The wear bar includes a main body portion having a forward wear bar end in opposed relation to a rearward wear bar end. An inner wear bar surface is positioned adjacent the outer surface of the chain's sidebar and is separated from an outer wear bar surface by a distance at least as great as the distance by which the chain's pin heads extend beyond the sidebars. In one embodiment, the upper edge of the wear bar includes a pair of semi-circular openings which fit closely adjacent the protruding pin heads. In another embodiment, the openings in the wear bar fully encircle the pin heads. A recess formed in the lower wear bar edge is used to weld the wear bar to the chain's sidebar. The lower edge of the wear bar may also be hardened to limit wear to the wear bar itself.

  • Patent number: 5416023
    Abstract: Biological samples are analyzed for benzodiazepines in a single isocratic analysis using a chromatographic column system containing an immobilized enzyme reactor which cleaves glucuronic acid-conjugated benzodiazepines, an anion exchange column, a hydrophobic cation exchange column and a reverse-phase analytical column. Preferred methods of performing the analysis further involve the use of a hydrophobic cation exchange precolumn prior to the anion exchange column. The system readily lends itself to automation, automatic periodic sampling and benzodiazepine identification and quantification. The system is particularly well adapted to the determination and identification of benzodiazepines in urine samples.

  • Patent number: 5365010
    Abstract: This invention is a process for the regeneration of a catalyst system component comprising certain transition aluminas promoted with a Lewis acid (preferably BF.sub.3) which have been used in the alkylation of isoparaffin with olefins. The process involves the calcination of the catalyst system component to volatilize and to oxidize the reaction product residue adhering to the solid catalyst. The process may include recovery and recycle of the involved Lewis acid.
