  • Phytases, nucleic acids encoding them and methods of making and using them
    Patent number: 7432097
    Abstract: In one aspect, the invention provides a purified and modified phytase enzyme from Escherichia coli K12 appA phytase. The enzyme has phytase activity and improved thermal tolerance as compared with the wild-type enzyme. In addition, the enzyme has improved protease stability at low pH. Glycosylation of the modified phytase provided a further improved enzyme having improved thermal tolerance and protease stability. The enzyme can be produced from native or recombinant host cells and can be used to aid in the digestion of phytate where desired. In one aspect, the phytase of the present invention can be used in foodstuffs to improve the feeding value of phytate rich ingredients.

  • Adhesive imaging member with composite carrier sheet
    Patent number: 6764804
    Abstract: The invention relates to an imaging element comprising a pragmatic imaging sheet comprising paper having a resin coat on each side, adhesively adhered to a carrier sheet with a pressure-sensitive adhesive, comprising at least one core layer of polyester and a rough lower surface layer.
    Type: Grant

  • Apparatus and method for controlling coating frowns in hopper coating
    Patent number: 5395653
    Abstract: The present invention relates to dual cavity hoppers and is an apparatus and method for controlling frowns. The dual cavity hoppers are provided with adjustable bypass means for providing fluid from the inner cavity to the outer cavity or alternatively for providing fluid directly to the outer cavity. The bypass means can be used on end-fed or center-fed dual cavity hoppers. The uniformity of the laydown across the width of the delivery slot is improved.

  • Coating hopper inserts
    Patent number: 5389150
    Abstract: The present invention describes slot inserts for use in a coating hopper having at least one metering slot. The slot inserts allow widthwise adjustment of the coating width. The slot inserts push fit into the metering slot and are held by friction between the walls of the metering slot. In one aspect of the invention, the inserts have different widthwise dimensions at each end allowing control over the edges. For dual cavity hoppers, the slot inserts can be shaped so as to prevent stagnant regions within the hopper cavities.
