Patent EP-0478827-A1 (EP)
Inventor: TOEPFER GOTTFRIED
IPC: C12N9/74
Filed: 1990-10-04
Abstract: The invention relates to stabilised thrombin, to a process for its preparation and to its use as reagent for determining the thrombin clotting time. The thrombin stabilised according to the invention contains a stabiliser mixture composed of     Stabiliser I:       HEPES buffer,   Stabiliser II:      thiomersal, Stabiliser III:     gelatin obtained by partial hydrolysis of collagen, and optionally   Stabiliser IV:      Polybrene.   The reagent is sensitive to heparin without stabiliser IV and is insensitive to up to 2 U of heparin/l with stabiliser IV. The stabilised thrombin is preferably in the form of an isotonic saline solution. The liquid  reagent has good storage stability and can be lyophilised without loss of activity. The lyophilisates are stable in a freeze-dried state. The accuracy and reliability of the determination of the thrombin clotting time can be considerably improved with this reagent. Likewise the user-friendliness of the method (determination with and without heparin influence) is increased. The reagent can be prepared in a straightforward manner and be repeatedly frozen and thawed without loss of activity.

Abstract: A method for separating HDL from whole blood anticoagulated with EDTA is disclosed. The method includes, as a first step, mixing the anticoagulated whole blood with an aqueous solution composed of magnesium cations and dextran sulfate 500 in such proportions and of such concentration
     (a) that substantially all of the LDL and VLDL lipoproteins and substantially all of the chylomicrons are precipitated while   (b) substantially all of the HDL remains in solution.    The method also includes the step of sedimenting the precipitated lipoproteins, the chylomicrons and the red blood cells by centrifuging, which can be low gravity centrifuging, and can include the step of determining the cholesterol, triglyceride, phospholipid or protein content of the supernatant. Also disclosed is a method wherein the reagent additionally contains a colored species which can be used to determine dilution of the supernatant, and which includes the additional steps of determining the dilution of the supernatant and the dilution factor, and multiplying the value determined for cholesterol, triglyceride, phospholipid or protein content of the supernatant times the dilution factor to determine the corresponding content of the blood sample.

Title: Method and apparatus for measuring registration between layers of a semiconductor wafer.
Inventor: INTO STEPHEN W
IPC: H01L21/02
Filed: 1990-02-08
Abstract: Method and apparatus for measuring displacement between layers of a semiconductor wafer wherein systematic errors associated with the measurement system are eliminated. An optical system, including a microscope and a camera, records an image of registration patterns on different layers of the wafer. The image is analyzed to measure displacement between the registration patterns. A first measurement is taken, the wafer is rotated by 180 DEG  about the measurement axis, and a second measurement is taken. The actual displacement between layers of the semiconductor wafer is calculated from the first and second measurements. Since the measured displacements change sign when the wafer is rotated and the systematic errors remain constant, systematic errors drop out of the calculated values of actual displacement. System errors can also be calculated for subsequent correction of measured values.

Abstract: A process for thermically recovering old sand obtained in casting plants and for treating dust containing combustible organic components and incombustible inorganic components is disclosed. Dust obtained by mechanical preparation of the old sand is separated from the sand. The sand is used to form a fluid bed in a fluid-bed kiln having a post-combustion space and an outlet for releasing combustion gases. Dust containing combustible organic components and incombustible inorganic components is introduced into the fluid bed, the combustion of the organic components being used to maintain reaction temperature in the fluid bed. The heat of the fluid bed and the post-combustion space deactivates inorganic components of the dust, which are transported by released combustion gases to effectively separate the inorganic components of the dust from the thermically recovered old sand. These deactivated inorganic components of the dust can be separated from the released combustion gases for easy disposal.

Abstract: As to data of an on-line system base sequencing apparatus, calibration coefficients for time bases of respective electrophoresis lanes are evaluated from differences between positions of signals already outputted in a range causing no sequence inversion and positions of substantially regular intervals for originally outputting signals, and time bases as to the respective electrophoresis lanes are calibrated with the calibration coefficients, thereby obtaining correct base sequence. Thus, the bases can be correctly sequenced even if electrophoresis speed difference is caused between the electrophoresis lanes.

Abstract: A platinum-silicon powder is electrophoretically deposited on a nickel- or cobalt-base superalloy substrate (12). The deposited powder is heated to form a transient liquid phase on the substrate (12) and to initiate diffusion of Pt and Si into the substrate (12). An aluminium-chromium powder is then electrophoretically deposited on the Pt-Si enriched substrate and diffusion heat-treated to form a corrosion- and oxidation-resistant Pt-Si-enriched diffused aluminide coating (14) on the substrate (12). The presence of both Pt and Si in the aluminide coating (14) unexpectedly improves coating ductility as compared to a Pt-enriched diffused aluminide coating without Si on the same substrate material.
