Abstract:
A dental irradiation device comprises a first light emitting unit for emitting blue light adapted for light hardening of a dental material. The device further comprises a second light emitting unit and an image sensing unit which are adapted for cooperation with each other for simultaneous illumination and image capturing. The device facilitates hardening of dental materials and provides, inter alia, additional diagnostic functions.

Abstract:
The invention relates to a rubber mixture, in particular for pneumatic vehicle tires, more particularly for the inner liner of a pneumatic vehicle tire, seat belts, belts and hoses. The rubber mixture is characterized by the following composition: 30 to 100 phr of at least one halobutyl rubber, 0 to 70 phr of at least one other diene rubber, 5 to 100 phr of at least one dry mixture compound containing at least 25% of at least one delaminated aluminohydrosilicate modification, the delaminated aluminohydrosilicate modification having a two-layer grid, 10 to 100 phr of at least one carbon black with an STSA surface as defined according to ASTM-D 6556 of from 10 to 60 m2/g and a DBP number defined according to ASTM-D 2414 of from 50 to 160 mL/100g, 3 to 20 phr of at least one mineral-oil softener, and other additives.
Abstract:
The invention relates to a traction rod (1) for bracing a crane jib, comprising a metallic tubular body (2) and coupling elements (3) which are connected to both ends thereof for an articulated connection of the traction rods among each other by means of bolts (5). According to the invention, the tubular body and the coupling elements consist of a one-piece tube portion, wherein the coupling elements are designed in each case as a thicker zone of the wall of the ends of the tubular body and are dimensioned in such a manner that a weakening of the cross section of the nominal wall thickness of the coupling elements, which has to be considered for calculating the load capacity of the tubular body, is prevented in the region of the bolt connection and the transition regions (7) from the respective thicker zones of the wall in the direction of the tubular body have a transition free of starting points for increasing fatigue strength.
Abstract:
The invention relates to substituted 5-(cyclohex-2-en-1-yl)penta-2,4-dienes and 5-(cyclohex-2-en-1-yl)pent-2-en-4-ines of the formula (I) and their salts where the radicals R1, R2, R3, R4, [X—Y] and Q are each as defined in the description, to processes for preparation thereof and to the use thereof for enhancing stress tolerance in plants with respect to abiotic stress, and/or for increasing plant yield.
Abstract:
The invention relates to substituted vinyl- and alkynylcyclohexenols of the general formula (I) and salts thereof where the R1, R2, R3, R4, R5, [X—Y] and Q radicals are each as defined in the description, to processes for preparation thereof and to the use thereof for enhancing stress tolerance in plants with respect to abiotic stress, and/or for increasing plant yield.
Abstract:
Use of substituted spirocyclic sulfonamidocarboxylic acids, -carboxylic esters, -carboxamides and -carbonitriles or salts thereof for enhancement of stress tolerance in plants.The invention relates to the use of spirocyclic sulfonamidocarboxylic acids, -carboxylic esters, -carboxamides and -carbonitriles or salts thereof of the formula (I) in which the respective substituents have the meanings given in the description, for increasing stress tolerance in plants with respect to abiotic stress, and also for increasing plant growth and/or for increasing plant yield.
Abstract:
The present invention relates to a truck mixer with at least one extension chute which for transport can be received on a holding means in a locked manner, wherein the holding means can be swiveled rotatorily and/or translatorily between a transport position and a removal position.
Abstract:
A process for continuous or quasi-continuous purification of a multi-component mixture by means of at least four individual chromatographic columns through which the mixture is fed by means of at least one solvent, is given, wherein the multi-component mixture is to be separated into an integer number n of fractions, wherein n is at least 5.
Abstract:
In a method for producing hot-rolled sections of steel with a rectangular or square cross-section, a substantially round pipe blank produced seamlessly by hot rolling or cold finished and welded and having a defined nominal outside diameter is initially produced and then formed at a forming temperature into a hollow section having the required cross-section, with visible edges C1 and C2 of the hollow section having a value ≦1.5×t (t=wall thickness). The pipe blank has a nominal outer diameter determined from a reduction ratio of the pipe blank to be achieved and the hollow section dimensions to be achieved, wherein the reduction ration lies within a range of −2% to −13% and is determined according to the following formula: Reduction ratio R[%]=[(2×(H+B))−π×D]×100%/[2×(H+B)].
