  • Patent number: 6162113
    Abstract: Featured is a method and system for cleaning abrasive sanding and/or planing media, for example sandpaper, wide belt sanding belts, planers, grinding wheels or other abrasive surfaces while the media is either in-situ in the sanding, planing, grinding equipment or when removed. Additionally, the cleaning featured method and system can clean the media while the abrasive media is being used as well as when the abrasive media is not being used. In the cleaning method dry ice (CO.sub.2, solid carbon dioxide) particles are propelled towards the abrasive surface at a high velocity so the dry ice particles impact on the surface of the abrasive media at a high velocity. Additionally, the dry ice (CO.sub.2, solid carbon dioxide) particles are propelled as to impact the abrasive surface at varying angles and locations as necessary to effectively clean the abrasive surface.

  • Patent number: 6017717
    Abstract: The present inventors have now discovered that humans have a gene that encodes a novel protein of the thymosin .beta. family. This novel protein, herein referred to as thymosin .beta.15, has the ability to bind and sequester G-actin, like other members of the thymosin .beta. family, but unlike what is known about other members it also directly regulates cell motility in prostatic carcinoma cells. The present invention is direct to an isolated cDNA encoding the human thymosin .beta.15 gene (SEQ ID NO: 1) and have deduced the amino acid sequence (SEQ ID NO: 2).

  • Patent number: 6004940
    Abstract: The present invention relates to a method by which one can target an undesired target molecule or target antigen, preferably an endogenous protein. The method comprises the intracellular expression of an antibody capable of binding to the target. A DNA sequence is delivered to a cell, the DNA sequence contains a sufficient number of nucleotides coding for the portion of an antibody capable of binding to the target operably linked to a promoter that will permit expression of the antibody in the cell(s) of interest. The antibody is then expressed intracellularly and binds to the target, thereby disrupting the target from its normal actions.

  • Patent number: 5998208
    Abstract: We have now discovered a helper virus free herpesvirus packaging system. This system can be used to package a wide range of desired nucleotide segments, preferably a DNA segment, into an empty herpesvirus particle because of the large genomes of herpesviruses. Preferably, the herpesvirus is an alpha herpesvirus. More preferably, the herpesvirus is an alpha herpesvirus such as Varicella-Zoster virus, pseudorabies virus, or a herpes simplex virus such as HSV-1 or HSV-2. Another preferred herpesvirus is Epstein-Barr virus.
