Abstract:
A rotary anode for a rotary anode X-ray tube has an anode disc with a supporting portion. A focal track is located in the vicinity of an outer diameter of the anode disc. The supporting portion has inhomogeneous material properties along a radial coordinate of the anode disc to provide a high mechanical load capacity in the area of an inner diameter of the anode disc and a high thermal load capacity at the focal track. These measures provide for a rotary anode for a rotary anode X-ray tube that meets the extreme thermal and mechanical loads during operation. Further, a method for manufacturing such a rotary anode is described as well.
Abstract:
The use of substituted fused pyrimidinones and dihydropyrimidinones of the formula (I) or salts thereof where the radicals of the formula (I) are each as defined in the description, for enhancing stress tolerance in plants to abiotic stress, and for invigorating plant growth and/or for increasing plant yield.
Abstract:
The present invention focuses on a process for the hydrogenation of aromatic or heteroaromatic compounds and in particular on the ring hydrogenation of compounds having the formula (I). Aromatic amino acids and amino alcohols can be successfully ring-hydrogenated using a platinum-rhodium mixed catalyst. The products can be used inter alia as mimetics in bioactive peptide active ingredients.
Abstract:
The present invention relates to novel substituted enaminocarbonyl compounds, to processes for their preparation and to their use for controlling animal pests, especially arthropods, in particular insects.
Abstract:
The invention relates to a sound damper for compressed air systems of vehicles. Said sound damper comprises a housing (1a, 1b), damping means (2) and at least one strut (3a, 3b, 3c). According to the invention, the housing (1a, 1b), has an air inlet (4) and an air outlet (5), the damping means (2) are boated in the housing (1a, 1b) and the strut or struts (3a, 3b, 3c) is or are located in the housing (1a, 1b) in such a way, that it or they protrude at least partially into the damping means (2). Air that flows through the housing (1a, 1b) from the air inlet (4) to the air outlet (5) is conducted by the strut or struts (3a, 3b, 3c). into the damping means (2).
Abstract:
The present invention relates to a process for preparing polyol esters by reacting polyols with linear or branched aliphatic monocarboxylic acids having 3 to 20 carbon atoms by partial recycling of the aliphatic monocarboxylic acid removed into the esterification reaction or into subsequent esterification batches.
Abstract:
Process for the obtention of HFC-227ea having a reduced content of organic impurities, comprising at least subjecting a crude HFC-227ea to two distillation steps at different pressures.
Abstract:
The invention relates to a linear actuator (1), at least including a stator (3) that is placed within a cartridge-like casing (2), a bearing ring (4) with a bearing seat for mounting a rotor (5) with an antifriction bearing (6), a spindle (7) that on its drive side (7.1) is together with the rotor (5) designed as motion transformer to transform the rotary motion into a translatory motion and a flange (9) that closes the casing (2) on the output side (8) of the linear actuator (1), the flange (9) being equipped with an anti-rotation locking device for the spindle output side (7.2) that penetrates the flange (9). According to the invention the cartridge-like casing (2) is provided with several formed bending tongues (10.1, 10.2), whereby in assembled condition first bending tongues (10.1) engage with groove-like recesses (11) of the bearing ring (4) of the antifriction bearing (6) and second bending tongues (10.2) engage with groove-like recesses (11) of the flange (9) so that all components (3, 4, 5, 7 and 9) placed in the casing are tensioned against each other without further connection techniques being required.
Abstract:
An apparatus is provided for filling an empty shaft tray with rod-shaped products. The shaft tray has shaft walls which form a plurality of shafts. The apparatus includes a filling hopper having a receiving region for a mass flow composed of the products, and a storage region for products comprising a front wall, a rear wall, side walls and a bottom wall. The storage region includes partitions that form a plurality of shafts adjacent to each other, wherein the partitions substantially extend over a full height of the storage region, and wherein the rear wall of the storage region includes openings for passage of the shaft walls of the shaft tray. A delivery element delivers the empty shaft tray into the receiving region of the filling hopper to be filled with the products. A removal element removes a filled shaft tray from the filling hopper.
Abstract:
The present invention relates to enhancement of the action of crop protection compositions comprising enaminocarbonyl compounds by the addition of ammonium salts and/or phosphonium salts or by the addition of ammonium or phosphonium salts and penetrants, to the corresponding compositions, to processes for their production and to their use in crop protection.
