Abstract: ABSTRACT A biochemical reagent comprises an oligosaccharide, preferably one which has been liberated from an immunogenic glycoprotein or proteoglycan, which is immobilized on a carrier via an intermediate spacer molecule such as a lipid. The lipid molecule should preferably have at least two long lipid tails so that the oligosaccharide is held in spaced relationship to the carrier where is exhibits antibody-binding ability which is almost indistinguishable from that of the original glycoprotein or proteoglycan. The reagent has its application in biochemical teating of oligosaccharides and systems which bind to them.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to an improvement of the known Ziegler catalyst which comprises a combination of a titanium-containing component and an organoaluminum component, and the present invention is characterized by a specific titanium-containing component.   Namely,  this titanium-containing component is obtained by contacting a known titanium-containing component of the Ziegler type catalyst which comprises Ti, Mg and a halogen, with an alkoxyalkylsilane compound which is characterized in that at  least  one  of  the  alkyl  groups  has  a  branched structure.   This catalyst does not require a so-called external  electron  donor,  and  no  reduction  of the polymerization velocity caused by the use of the electron donor  is  entailed.    When  this  catalyst  is  used,  a propylene/ethylene block copolymer in which the molecular weight of the propylene/ethylene copolymer portion and/or the  polyethylene  portion  is  increased,  that  is,  the rigidity  and  impact  strength  are  increased,  can  be prepared.

Title: Rotary machining tool and method of its manufacture
Inventor: WRIGHT JAMES L
IPC: B23C5/22
Filed: 1987-02-24
Granted: 1990-04-24
Abstract: 11 P1 13054b ROTARY MACHINING TOOL AND METHOD OF ITS MANUFACTURE ABSTRACT OF THE DISCLOSURE The present invention is a rotary machining tool and a method of making it using an easily replaceable cutter element assembly. A circular saw is exemplary of a cutting tool which can be made using the present invention. The cutter element assembly comprises two portions. The first is an inverted, generally U-shaped clevis with spaced apart side portions that fit over the circumferential edge of a sawplate. The clevis has an upper portion which extends outwardly from the sawplate edge thereby defining a tooth retaining socket between the sawplate edge and the clevis. The side portions of the clevis are apertured to accept a pin for attachment to the sawplate which has a corresponding aperture. A buttress attached to the clevis normally bears against the leading edge of a gullet and prevents rearward rotation when in use. The second member is an insertable tooth having a head and an elongated tapered shank. The shank has a taper on its upper surface sufficient to form a self-releasing taper, ususally between 3° and 10°. The sides of the shank have less taper so as to form a self-locking taper, typically between 0° and 2.5°. The tooth shank is driven into the socket formed between the clevis and the sawplate. As the tooth is driven in, the clevis is forced radially outward against the attaching pin so as to tightly lock the assembly until the tooth is again driven out for sharpening or replacement. While the teeth may be sharpened in place on the sawplate, it is frequently advantageous to disassemble the saw and sharpen the teeth seperately. This permits a number of grinding configurations to be used which are not otherwise possible when the saw is fully assembled. The only tools required for saw assembly and disassembly are a hammer and punch. A 1.5 m diameter saw having 60 teeth can be completely retoothed in place in as little as 6 minutes.

Abstract: Monoclonal antibodies specific for the glycosylated lysine residue at position 525 in glycoalbumin and a method for producing such antibodies. The monoclonal antibodies are useful as reagents in immunoassays for the specific determination of glycoalbumin in human blood samples which is indicative of the severity of the diabetic condition.  The monoclonal antibodies are secreted by hybridomas obtained by fusing a myeloma cell with a lymphocyte that has been taken from an animal, usually a mouse, immunized with a peptide immunogen and which produces antibody to the lysine 525 residue in glycoalbumin.  The synthetic peptide immunogen comprises a peptide residue which includes an .epsilon.-amino glucosylated lysine and an adjacent amino acid sequence in which at least one of the amino acid units is in a position corresponding to the peptide sequence of human albumin adjacent to lysine 525, the glycosylated peptide residue being linked to an immunogenic carrier.
