  • Filter Media
    Publication number: 20160160815
    Abstract: A filter media includes flutes, forward plugs, and aft plugs. Each of the flutes has a forward flute face, an aft flute face, and a flute body defining a flute conduit to convey the fluid. The forward plugs are disposed in alternating ones of the flutes. Each forward plug includes a plug base and an aerodynamic plug nose. The aerodynamic plug nose has a center axis and a nose surface tapering outwardly from the center axis towards the plug base. The plug nose is configured to aerodynamically redirect a flow of the fluid away from the center axis. The flutes that have forward plugs include a flute outlet disposed at the aft flute face. The aft plugs are disposed in the flutes adjacent to the flutes that have corresponding forward plugs. The flutes that have aft plugs include a flute inlet disposed at the forward flute face.

  • Method of making isoidide
    Patent number: 9340552
    Abstract: Disclosed is a process for the preparation of isoidide from isosorbide. An aqueous solution of isosorbide is subjected to epimerization in the presence of hydrogen under the influence of a catalyst comprising ruthenium on a support, preferably a carbon support. The process of the invention can be conducted using a relatively low hydrogen pressure, and leads to a desired distribution of epimers, favoring isoidide over isomannide and isosorbide.

  • System and method for improving cache performance
    Patent number: 9336157
    Abstract: A method, computer program product, and computing system for receiving a Mode Select command concerning a single LUN from each of a plurality of potential hosts. Each Mode Select command defines control information and host identifier information concerning the potential host associated with the Mode Select command. The received Mode Select commands are processed serially and in accordance with the order in which the Mode Select commands were received. The first Mode Select command received is accepted and subsequent Mode Select commands received are rejected, thus defining an accepted Mode Select command and one or more rejected Mode Select commands. The control information and host identifier information included within the accepted Mode Select command are written to a buffer associated with the single LUN. The buffer includes a control field and a GUID field.
