  • Porous pipe and process for producing same
    Patent number: 5660209
    Abstract: A process for producing a porous pipe is disclosed and comprises forming an extrudable mixture comprising elastomer particles, binder component and a solid water carrier component having a composition other than the elastomer particles and the binder component and being associated with sufficient water to provide porosity to a porous pipe produced from the mixture; and extruding the extrudable mixture to conditions effective to form the porous pipe.
    Type: Grant
    Filed: August 1, 1995
    Date of Patent: August 26, 1997
    Assignee: Subsurface Technology Corp.
    Inventors: James J. Franz, Richard A. Hutchinson
  • Truck box cap
    Patent number: 5655809
    Abstract: The present invention provides a truck box cap for use with light duty trucks and similar vehicles having open cargo boxes. The truck box cap provides a side profile defining a horizontal upper portion, a sharply inclined second portion and a more gradually inclined third portion extending to the tail gate. The truck box cap comprises fixed side walls, a horizontal uppermost cover member at the first portion, and a plurality of telescoping cover members lying along the third portion. Slidable connection means support the telescoping cover members for sliding movement between a covered position enclosing a portion of the truck box and a retracted position underneath the uppermost cover member exposing a portion of the truck box.

  • Process for preparing daunorubicin
    Patent number: 5652125
    Abstract: The ability to improve the conversion of .epsilon.-rhodomycinone to daunorubicin can be conferred on a bacterial host transformed with a recombinant vector comprising a DNA coding for an appropriate protein useful for that conversion. Furthermore, the bacterial host may have a mutation that blocks the function of a gene of daunorubicin metabolism.
