Abstract: The present invention relates to variants of an alpha-amylase having improved stability to chelating agents relative to its parent enzyme, compositions comprising the variants, nucleic acids encoding the variants, methods of producing the variants, and methods for using the variants.

Abstract: The invention relates to a deburring tool for deburring abutting edges at orthogonally and obliquely extending transversal boreholes having a diameter of less than 10 mm in a component, such as an engine block, an injection system for combustion engines, a valve block and a camshaft or transmission shaft. The deburring tool is moved in a rotational and/or translatory manner and comprises a tool shaft (1), which is provided with a clamping end (2), and a tubular shaft part (5), characterized in that said tubular shaft part holds one or several cutting bodies (11) with a cutting blade (3), the cutting bodies being mounted in a movable manner in a passage (10), and in that a substance that is pressed under pressure into the through-bore (7) of the tool shaft (1) displaces the blade(s) to the exterior. The deburring tool is configured as a single piece and can be produced at low cost. Different blade geometries remove the burr by means of high speed deburring.

Abstract: The electrostatic separation of ground crude potassium salts containing kieserite is accomplished by mixing the ground crude potassium salt with a conditioning agent containing a combination of an aromatic carboxylic acid or its derivatives, an ammonium salt of an aromatic carboxylic acid, as well as an unbranched fatty alcohol having a chain length of C10 to C15, and subsequently triboelectrically charging the mixture at a relative humidity of 1-10%. The mixture is then separated into a crude kieserite fraction and a crude potassium fraction by means of an electrostatic separation method. This method increases kieserite yield and the selectivity of a subsequent treatment by means of flotation.

Abstract: The invention pertains to a deburring tool for deburring the interior and/or exterior of work pieces, for example, abutting edges on intersecting bores or on longitudinal and transverse grooves in bores or on transverse bores in a deep-hole bore with different diameters of an engine block, tubular work piece ends, edges on and in flat work piece surfaces or surfaces of a toothed wheel or a sprocket wheel. The deburring tool can be used in machine tools and is pressure-controlled. The cutting forces can be variably adapted to the burr dimensions that change during the machining process and to different materials. Corresponding embodiments of the deburring tool ensure the deburring of different work pieces with a good quality and in a short period of time. The inventive deburring tool is particularly advantageous in that it can be used in intermittent assembly lines with the latest manufacturing technologies.

Abstract: In an example embodiment, an approach for financial transaction processing involves using regulatory type rules at a banking institution for processing financial transactions involving a non-banking financial institution, such as a funds transfer service. An assimilation processing module and underlying processing modules determine whether the funds-transfer request should be reported as at least one of funds-related activity involving the banking institution and funds-related activity involving the financial institution.

Abstract: The invention relates to an object (20) with information (16) to be secured provided thereon, such as a coding, identification, PIN number or the like, and a security cover sticker (18) for covering the information (16) to be secured. The object (20) and the information (16) to be secured have disposed therebetween an additional layer (30) whose adhesive power to the cover sticker (18) is greater at least in partial areas than the adhesive power of the additional layer (30) to the object (20).

Abstract: The invention pertains to a deburring tool for deburring the interior and/or exterior of work pieces, for example, abutting edges on intersecting bores or on longitudinal and transverse grooves in bores or on transverse bores in a deep-hole bore with different diameters of an engine block, tubular work piece ends, edges on and in flat work piece surfaces or surfaces of a toothed wheel or a sprocket wheel.

Abstract: The present invention relates to a process for treatment of the surface of a workpiece of aluminum or of an aluminum alloy, which is characterized in that the workpiece is brightened in an aqueous electrolyte by application of an electric d.c. voltage, the electrolyte having the following composition per liter of water: 1 H2SO4 (sulfuric acid) 85 to 340 g/l H3PO4 (phosphoric acid) 850 to 1360 g/l Al (aluminum) 8.5 to 43 g/l.

Abstract: The method of applying adhesive to a substrate is performed by an installer donning a pair of shoes having pins extending from the undersurface thereof and using a notched spreading edge squeegee having an elongate handle to push adhesive from the configuration of a puddle to a configuration of parallel spaced apart lines of adhesive, the installer being capable of walking forwardly being the squeegee and further being capable of walking across the lines of adhesive without adversely affecting desired quality of adhesion.
