  • Patent number: 9821425
    Abstract: A method for subcooling liquid cryogen that is used by a cutting tool uses the steps of dividing liquid phase cryogen between a subcooler feed line and tool feed line. The cryogen in the subcooler feed line is expanded to lower the pressure and decrease the temperature of the cryogen, and the expanded liquid cryogen from the subcooler feed line is added to the interior of a subcooler. A heat exchanger is positioned in the subcooler in contact with the expanded liquid cryogen. The cryogen in the tool feed line is subcooled below its saturation temperature by passing the cryogen through the heat exchanger, and the subcooled cryogen from the heat exchanger is supplied to the cutting tool. As a result, the subcooled cryogen supplied to the cutting tool is substantially 100% liquid cryogen without any vapor content.

  • Patent number: 9771426
    Abstract: Methods and compositions involving polypeptides having an aglycosylated antibody Fc domain. In certain embodiments, polypeptides have an aglycosylated Fc domain that contains one or more substitutions compared to a native Fc domain. Additionally, some embodiments involve an Fc domain that is binds some Fc receptors but not others. For example, polypeptides are provided with an aglycosylated Fc domain that selectively binds Fc?RIIa, but that is significantly reduced for binding to the highly homologous Fc?RIIb receptors. Furthermore, methods and compositions are provided for promoting antibody-dependent cell-mediated toxicity (ADCC) using a polypeptide having a modified aglycosylated Fc domain and a second non-Fc binding domain, which can be an antigen binding region of an antibody or a non-antigen binding region. Some embodiments concern antibodies with such polypeptides, which may have the same or different non-Fc binding domain.

  • Publication number: 20170173706
    Abstract: A rotating cutting tool that is internally cooled by cryogenic fluid has a generally cylindrical outer shape. At least one flute is formed on the cutting tool and a cutting edge is formed on an outer edge of the flute for cutting a workpiece. An internal cold flow delivery path for cryogenic coolant is in proximity to the cutting edge. A coolant cavity is formed in the cutting tool for supplying cryogenic coolant to the internal cold flow delivery path and a return path for cryogenic coolant is downstream from the cold flow delivery path. An exhaust port is coupled to the return path for exhausting cryogenic coolant to atmosphere. The exhaust port is remote from the cutting edge so that the cryogenic coolant is exhausted away from the cutting edge and away from a workpiece so that the cryogenic coolant does not cool and toughen the workpiece.

  • Publication number: 20170128553
    Abstract: Compositions and methods for the treatment of cancer are described, and, more preferably, to the treatment of cancers that do not express, or are otherwise deficient in, trgininosuccinate synthetase, with enzymes that deplete L-Arginine in serum. In one embodiment, the present invention contemplates an arginase protein, such as a human Arginase I protein, comprising at least one amino acid substitution and a metal cofactor, said protein comprising an increased catalytic activity when compared with a native human Arginase I.

  • Publication number: 20170058030
    Abstract: In some aspects, mutant or variant Fc domains are provided that can exhibit increased affinity or selectivity for Fc?RIIB. The variant Fc domain may be a mutant IgG1 Fc domain. In some embodiments, a mutant or variant Fc domain may be present in a therapeutic antibody such as, e.g., an agonistic antibody. Additional methods for using and identifying mutant Fc domains are also provided.
