Patent TR-25017-A (TR)
IPC: C07C49/76
Filed: 1990-11-29
Abstract: A method is provided for separating hydrogen fluoride (HF) from a mixture comprising HF complexed with an aromatic ketone in which the keto carbon atom is directly bonded to an aromatic ring carbon atom, e.g., 4-isobutylacetophenone, by adding a carboxylic acid anhydride, e.g., acetic anhydride, to the mixture while maintaining the mixture at conditions sufficient to sustain a reaction between the anhydride and the HF to form the corresponding acyl fluoride, e.g., acetyl fluoride, and carboxylic acid, e.g., acetic acid, and separating the acyl fluoride from the mixture. The method is conveniently carried out in a stripping column near the top of which the mixture comprising aromatic ketone and HF is fed and below which the anhydride is fed. Between these feed points, the uncomplexed HF is stripped from the mixture, while below the anhydride feed point or points, the anhydride reacts with the complexed HF to form the acyl fluoride which is stripped from the mixture, and the carboxylic acid. The separation method may be integrated with the production of the aromatic ketone by the Friedel-Crafts acylation of an aromatic compound, e.g., isobutylbenzene with an acyl fluoride, a carboxylic acid anhydride, a free carboxylic acid, or a mixture of the foregoing reactants, using an excess of HF as catalyst, to produce the mixture comprising aromatic ketone and HF to be separated, and to which the separated HF and in some cases the acyl fluoride may be recycled.

Patent AU-1680302-A (AU)
Title: Flexible stent
Inventor: MAJERCAK DAVID C
IPC: A61F2/06
Filed: 2002-02-21
Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.

Patent AU-1823199-A (AU)
Title: Nucleic acid ligand diagnostic biochip
Inventor: GOLD LARRY
IPC: C12Q1/68
Filed: 1998-12-14
Abstract: A nucleic acid ligand "biochip" is disclosed, consisting of a solid support to which one or more specific nucleic acid ligands is attached in a spatially defined manner. Each nucleic acid ligand binds specifically and avidly to a particular target molecule contained within a test mixture, such as a bodily fluid. The target molecules include, but are not limited to, proteins (cellular, viral, bacterial, etc.) hormones, sugars, metabolic byproducts, cofactor, and intermediates, drugs, and toxins. Contacting the test mixture with the biochip leads to the binding of a target molecule to its cognate nucleic acid ligand. Binding of target to the nucleic acid ligand results in a detectable change at each specific location on the biochip. The detectable change can include, but is not limited to, a change in fluorescence, or a change in a physical parameter, such as electrical conductance or refractive index, at each location on the biochip. The biochip will then be read by a device, such as a fluorescence scanner or a surface plasmon resonance detector, that can measure the magnitude of the change at each location on the biochip. The location of the change reveals what target molecule has been detected, and the magnitude of the change indicates how much of it is present. The combination of these two pieces of information will yield diagnostic and prognostic medical information when signal patterns are compared with those obtained from bodily fluids of individuals with diagnosed disorders. In principle, the biochip could be used to test any chemically complex mixture provided that nucleic acid ligands to components suspected of being present in the mixture are attached to the biochip. Thus, the nucleic acid ligand biochip will have a wider use in environmental testing, etc.

Patent AU-1872992-A (AU)
Title: Quantitative clotting assay for activated factor vii
IPC: C12Q1/56
Filed: 1992-04-09
Abstract: An kit for an assay for measuring activated factor VII (factor VIIa) is disclosed which employs a reagent comprising truncated tissue factor (tTF), a soluble mutant form of tissue factor (TF) that retains the cofactor function of TF toward factor VIIa, but does not support the conversion of factor VII to VIIa. As a result, the tTF assay for factor VIIa is free from interference from factor VII in the plasma and is therefore specific for factor VIIa. The assay is much simpler than existing assays, because it is a single-stage clotting assay performed almost identically to a prothrombin time (PT) assay. It is also considerably more sensitive than current assays for factor VIIa in plasma. Since the tTF assay is calibrated against a factor VIIa standard, it yields an absolute concentration of factor VIIa in ng/ml.
