  • Publication number: 20120132591
    Abstract: A novel zeolite membrane is manufactured using zeolite seeds that are deposited on a support material. The seeds are then further grown in a secondary growth step to form a membrane with inter-grown particles. The pore size of the zeolite membrane is in a range between 3 angstrom and 8 angstrom, which allows water to flow through the membrane at a relatively high flux rate while excluding dissolved ions. The novel zeolite membrane is surprisingly efficient for desalinating sea water using reverse osmosis. The zeolite membrane is capable of high rates of water flux rate and high percentage of ion rejection.

  • Patent number: 8136435
    Abstract: A food product slicer knife includes a circular knife body with a peripheral cutting edge. A central opening passes through the knife body and includes a pair of diametrically opposed outwardly extending slots. The knife body also includes at least one set of diametrically opposed drive pin receiving openings spaced outwardly of the central opening and circumferentially offset from the diametrically opposed outwardly extending slots. A tool assembly is adapted to facilitate knife installation and removal and holds the knife when removed from a slicer. A food product slicer includes a knife mount hub adapted to cooperate with the knife to hold the knife on the slicer during operation.
