Abstract: ABSTRACT           A method of providing an undercut "bowtie" slot in the head of a fastener such as a screw or bolt, and the resulting interim and final fastener products.  The method consists of only two heading steps, starting with either a preform or a simple blank.  In the first heading step a forming blow is applied which produces a "bowtie" shaped slot having side walls that are not undercut and a single, continuous ellipsoidal bulge projecting upwardly from the head adjacent to and substantially coextensive with each edge of the slot. In the second heading step a forming blow is applied which compresses the material of the ellipsoidal bulges down into the head to form a radiused undercut slot con-figuration that is continuous and substantially coextensive with the length of the slot.

Abstract: Robert Paul Cory STABILIZED GLUCOSE ?MERASE ENZYME CONCENTRATE AND PROCESS FOR PREPARING THE SAME                     ABSTRACT OF THE DISCLOSURE      A stabilized glucose isomerase enzyme concentrate comprising a substantially water soluble and nucleic acid-free enzyme con-centrate of (1) a cell-free glucose isomerase enzyme and (2) a substantially water soluble magnesium salt characterized as having:          (a) a protein content ranging from about 50 to about 80%, by weight, dry basis;  (b) a Mg++ content ranging from about 3 to about 45 mg. of Mg++ per ml. of enzyme concentrate; (c) a Mg++/protein ratio ranging from about 0.02 to about 0.75; (d) a specific isomerase activity of at least about 10 IGIU/mg of protein; and (e) a stability such that it retains at least about 95%    of its initial isomerase activity when stored at 26°C. for up to 30 days and 80?10% of its initial isomerase activity when stored at 18°C. for up to one year.          The enzyme concentrate will generally have an isomerase activity of at least 5,000 IGIU/gram, dry basis and preferably at least 8,000 IGIU/gram, dry basis, and contain a water miscible organic solvent such as 2-propanol.  The stabilized enzyme concentrate is prepared by contacting an aqueous mixture containing cell-free glucose isomerase and a water miscible organic solvent with a small, but effective amount of a substantially water soluble magnesium salt.          This treatment causes the formation of an enzyme-magnesium precipitate.          The precipitate (the stabilized enzyme concentrate) can be recovered by conventional techniques such as by centrifugation.  The stabilized enzyme concentrate can be used to place a high level of enzyme per unit volume on most water insoluble carriers (e.g., DEAE cellulose; synthetic anion exchange resins; porous, water insoluble materials such as basic magnesium carbonate and porous alumina materials) to form a biocatalyst useful to continuously convert glucose to fructose.

Abstract: A BROADBAND TWO-PORT ISOLATOR    ABSTRACT      A non-reciprocal signal path for RF over a broadband frequency range is provided by an isolator comprising two coils or meshes positioned at 90° to each other adjacent at least one gyromagnetic or ferrite disc which is magnetically biased by a static magnetic field.  Each coil is tuned by a parallel capacitor, each coil and capacitor having one end grounded to a surrounding electromagnetic shield.  A resistive unilateralizing element is coupled between the input and output terminals and, being essentially non-reactive, provides the broadband characteristic.  The energy from the reverse direction is dissipated externally in the resistive element.          A magnetic return path of a high permeability material allows the use of smaller biasing magnets and reduces the effects of external magnetic fields.

Abstract: ABSTRACT OF THE DISCLOSURE Heparin has been available for a long time as a naturally-occurring anticoagulant, and is now becoming increas-ingly inportant.  A number of methods for isolating heparin from animal tissues such as the lungs, liver and intestinal mucus of pigs, cattle and sheep are known.  According to the present invention, heparin is recovered from intestinal brine formed by treatment, with aqueous sodium chloride solution or solid sodium chloride in the presence of water, of animal intestines from which intestinal mucus has been removed.  The heparin recovered is almost completely free of byproducts and heparin of good quality is obtained.
