Granted: 1991-12-27
Abstract: In a method of flaw classification on and in welds of planar or arcuate plate-shaped workpieces of uniform thickness by means of ultrasonics, the expected flaw areas of the workpiece are pre-examined manually and are then examined systematically using the ultrasound echo image method in separate cross-sectional planes. A B-scan is thus generated, and changing the position of the transducer on the workpiece and/or the transmitting direction enables defects to be located by calculating the delay time of ultrasound waves in the go-and-return directions within the workpiece under consideration of possible reflections at the rear side (8) of the workpiece. For defining the test conditions, part-specific parameters are considered, such as weld type and weld shape (e.g., double-V-weld and bell seam), weld geometry (e.g. seam angle), and part characteristics (e.g. wall thickness), whereupon with the aid of a computer into which the parameters have been inputted, a graphic representation corresponding to a B-scan is generated. In the graphic representation at least one area, in which the density of obtained reflection points per unit of area exceeds a predetermined value, is surrounded by a closed curve of second order, generally an ellipse, and the angular direction of a privileged axis, particularly the major axis of the ellipse, in relation to a reference system, the axis ratio and/or the center location are calculated. Reflection points, located opposite from each other, of a defect are detected, and the ratio between length and thickness of the defect or the orientation tendency, respectively, is calculated, whereupon at least by logically linking orientation tendency and path difference a discrimination between volumetric-type defects, planar defects and a combination of such defects is brought about.

Title: Protein purification

Granted: 1995-03-22
Abstract: Chromatographic procedures are individually and jointly applied to the rapid and efficient isolation of biologically active proteins and especially glycoproteins such as recombinant erythropoietin present in the medium of growth of genetically transformed mammalian host cells. Illustratively, recombinant EPO is isolated from culture fluids by reverse phase chromatography employing a C4 or C6 column and elution with ethanol. Recombinant erythropoientin may also be purified by anion exchange chromatography employing, e.g., a DEAE resin, with preliminary selective elution of contaminant materials having a lower pKa than erythropoietin from the resin under conditions mitigating against acid activated protease degradation. Practiced serially, the two chromatographic procedures allow for high yields of biologically active recombinant erythropoietin from mammalian cell culture media.

Granted: 1992-02-12
Abstract: An aircraft towing vehicle has a rearwardly opening recess adapted to receive the nose wheel of an aircraft to be towed. A nose wheel lifting and clamping mechanism has two nose wheel lifters which can be pivoted from a retracted position, in which they are parallel to sides of the vehicle frame, into an operative position, in which they extend into the recess for engaging the aircraft nose wheel. The lifters pivot on rocker arms which themselves pivot about a horizontal axis and are power driven by hydraulic actuators. A separate hydraulic swivel drive motor is provided for each lifter. The pressure increase which takes place when the swivel drive reaches the end of its path is used to initiate the delivery of pressurized fluid to the actuator. A crank arm driven by the hydraulic motor is connected to the support for the lifter with a low back pivot, self locking linkage to positively prevent even excessive forces generated during the nose wheel lifting process from unintentionally moving the lifters towards their retracted positions.

Title: Method of modification of the reflection coefficient of the extremity of a monomode fibre and fibre interferometer fabricated using such method
IPC: C03B37/14
Filed: 1988-03-14
Granted: 1992-05-13
Abstract: The invention relates to the treatment of the extremities of a monomode optical fibre so as to give them, for example, a reflection coefficient sufficient for forming a Fabry-Perot interferometer therein. A plane face, optionally inclined, is obtained by cleaving. A brief heating deforms this face and causes a convex dome 5 to appear which occupies the central zone of the deformed face 7 and which, facing the core 20, no longer has a small residual inclination. Dielectric layers such as 32 are then directly deposited onto this face so as to form a reflective coating. The invention is applicable, for example, for controlling the frequency of a semiconductor laser which can be used for telecommunication. <IMAGE>

Abstract: The invention relates to an electromagnetic switchgear, in particular circuit-breaker. 
<??>With electromagnetic switchgear, in particular contact breakers, there is a significant requirement for constructing the circuit-breakers to be bounce-free. Due to the striking of the contact bridge support at the end of the switch-off process on the housing, particularly when plastics such as thermoplasts are used for the contact bridge support, rebouncing phenomena have been almost unavoidable. The present invention is intended to reduce these rebouncing phenomena substantially. 
<??>This is done by providing projections on the housing which are of unequal height in the movement direction of the armature, and which can project through openings of the contact bridge support so that the projections can come into contact with a metal part, preferably the armature itself, during switching off. 
<??>Electromagnetic switchgear with alternating current and also direct current magnet system.
