Abstract: A method of gluing a first metal part to a second part includes the steps of providing a first metal part such as a steel part, and the second part such as a second metal part, treating a surface portion of the first metal part intended for being glued to the second part with laser pulses so that a surface layer of the first metal part across the surface portion is removed, preferably by ablation, while applying laser pulses to the surface portion of the first metal part also applying a pressurized air or gas stream to the surface portion, applying an adhesive to at least the surface portion of the first metal part and/or to a surface of the second part, and gluing the first metal part and the second part together.

Abstract: Method for preparing certain oximes and oxime O-methyl ethers by reacting poorly water-soluble carbonyl compounds with salts of hydroxylamine or hydroxylamine O-methyl ether or the free base of hydroxylamine in the presence of certain phosphoric esters or salts thereof of the formula (I) wherein R1, R2 and X are defined as specified in the description.

Abstract: The present invention relates to a process for preparing dithiinetetracarboximides by reaction of succinic monoamides with thionyl chloride, with continuous performance of at least one of the process steps.

Abstract: The invention relates to a device for counting objects fed as bulk material, comprising a first feeding unit for pre-counting a first fixed subset of a target quantity of objects and a second feeding unit for preferably separately feeding a second subset of the target quantity of objects, wherein the device (1, 7, 10) is designed such that the quantity of objects of the first subset is transmitted to a control apparatus (5), which controls the second feeding unit such that the second subset of objects is fed enough objects that the second subset of objects corresponds to the difference between the first subset and the target quantity of objects, and the first subset of objects is poured into the second subset of objects.

Abstract: A device and a method for detecting deposits (9) on walls (2) that are covered by a medium, in which as sensor (1) is integrated in the wall (2). A component (3) of the sensor (1) locally heats the medium in a region (4), and the temperature of the medium around the component (3) is detected. The sensor (1) relays temperature measurement signals to an analysis unit (8), where the degree of deposit formation is determined, e.g., by comparison with stored reference data.

Abstract: The present invention relates to an optically variable security element for protecting articles against counterfeiting, to a process for the production of a security element of this type, and to the use thereof.

Abstract: The invention relates to a process for esterifying free fatty acids in vegetable and animal fat with alcohols over heterogeneous acidic ion exchange resin catalysts at temperatures of 60 to 120° C.

Abstract: Continuous method for the esterification of free fatty acids in plant and animal fats with alcohols using a heterogenic acid catalyst.

Abstract: The invention relates to a pigment mixture consisting of at least two constituents, constituent A being uncoated, monocoated or multicoated glass lamellae, and constituent B being nacreous pigments based on phyllosilicates, SiO2 lamellae, Fe2O3 lamellae or Al2O3 lamellae. The invention also relates to the use of said pigment mixture, inter alia, in paints, dyes, especially printing inks, plastics, powder paints, pastes and cosmetic formulations.
