Patent CA-2006684-A1 (CA)
Inventor: ESMON CHARLES T
IPC: C12P21/08
Filed: 1989-12-27
Abstract: A Ca<2+> dependent monoclonal antibody that specifically binds to a specific twelve peptide sequence (E D Q V D P R L I D G K) in the activation region of the protein C. The antibody does not bind to activated protein C and can be used to inhibit activation of protein C by thrombin-thrombomodulin. The antibody can be isolated from cell culture or ascites fluid in large quantities by affinity chromatography with mild conditions using the peptide bound to an immobilized substrate. The antibody has a number of specific uses in isolation and characterization of protein C and as a model for the design of Ca<2+> dependent antibodies for the isolation of other proteins, as a diagnostic, and as a therapeutic to prevent activation of protein C. The protein c can be naturally produced or produced by expression of the recombinant gene. Advantages of the antibody in purification of protein C include the specificity for protein C and not activated protein C, and the unique Ca<2+>-peptide binding specificity which allows the binding site to be protected when it is being immobilized on the chromatographic support. In vivo, the antibody has been demonstrated to inhibit tumor growth. The antibody can also be used to promote clotting in patients having high levels of Factor VIII inhibitors.

IPC: C07C51/58
Filed: 1990-01-12
Abstract: Abstract of the Disclosure              HOE 89/F 007 A process for the oligomerization of hexafluoropropene oxide A process for the preparation of perfluorinated carbonyl fluorides from hexafluoropropene oxide (HFPO)  is des-cribed, in which HFPO is oligomerized in an aprotic polar solvent in the presence of a tertiary diamine in the absence or presence of at least one protonic compound. Preferably employed are tetraalkyl-substituted tertiary aliphatic diamine compounds. Protonic compounds which are possibly and preferably used are water, methanol, glycol, ammonia or diethylamine. The selectivity can be displaced in favor of shorter-chain oligomers, in particular of the dimer, by an increased content of these compounds.

Abstract: ABSTRACT OF THE DISCLOSURE    A vacuum guide roll apparatus is disclosed for guiding a web between an upstream dryer and a downstream dryer of a dryer section.  The apparatus includes a perforate roll shell having a first and a second end.  The shell defines an elongate chamber which extends between the first and the second ends.  A first and second shaft are rigidly secured to and disposed coaxially relative to the shell.  The shafts are disposed adjacent to the first and second ends respectively of the shell.  The shafts define respectively a first and second journal.  A first and second bearing cooperate with the first and second journals respectively for rotatably supporting the roll shell.  A housing is disposed coaxially relative to the shell and adjacent to one of the shafts.  The housing defines a passageway which is connected to a source of partial vacuum.  A first annular seal is disposed between the housing and the one shaft for sealing the housing relative to the one shaft.  A second annular seal is disposed between the housing and the shell for sealing the housing relative to the shell so that when the shell rotates relative to the housing, the passageway is sealingly connected to the elongate chamber such that a partial vacuum is generated within the chamber for urging the web towards the perforate shell.

IPC: E02F3/36
Filed: 1990-10-17
Abstract: CARRIER FRAME FOR A QUICK COUPLER                    ABSTRACT OF THE DISCLOSURE A quick attachment holder for connecting an attachment to the boom arms of a loader includes right-hand and left-hand end portions connected by a semi-rigid cross tube, without additional structural cross members.  A pin connection of the holder end portions to the tube causes the left- and right-hand end portions to generally move together while permitting several degrees of relative rotational movement between end portions to aid in the reconnection of the attachment even when there is slight misalignment between the holder and the attachment.  The cross tube is located on the pivot center of the holder so that only torque loads are applied to the tube. The pin connection will shear if the tube is accidentally over-torqued, and individual components of the holder are replaceable.

Title: Film ghost removal in electrographic plotters by voltage bias of the plotter fountain or film edge-strip
Inventor: HANSEN LORIN K
IPC: H04N1/29
Filed: 1990-11-30
Abstract: A preferred embodiment of the present invention is directed to a removal of a ghost image created during a processing of a film laminate medium by an electrographic plotter.  A recording of an image on the film medium induces a ghosting potential over a developing station.  The ghosting potential causes a spurious image to be developed by the developing station.          The recorded image is created by depositing a charge on a dielectric layer of the film.  A relationship exists between the deposited charge and the ghosting potential.  By use of information known to the system, the ghosting potential may be estimated and reduced.  A preferred method estimates the magnitude of the ghosting potential by use of the relationship between deposited charge and ghosting potential.  A counteracting potential is applied to the system to reduce the ghosting potential over the developing station.  The reduction of the ghosting potential substantially removes the ghost image created during the processing of the film laminate.
