Abstract:
The invention relates to a method for weaving fabrics that comprise in at least some sections multiple layers, especially one-piece woven (OPW) airbags comprising single-layer, double-layer and multi-layer sections. According to the inventive method, weaves or weave combinations are produced in the double- or multi-layer sections that are different from the plain weave.
Abstract:
The present invention provides a nanoparticle-filled polymer comprising one or more nanoparticles dispersed within the one or more polymeric materials, wherein the one or more nanoparticles have a diameter of between 0.1 nm and 100 nm, wherein the nanoparticle-filled rubbery polymer behaves as a nanocomposite exhibiting higher permeability than the native polymer membrane.
Abstract:
The invention relates to an exhaust gas turbocharger (1) comprising an exhaust gas turbine (2) with an adjustable guide apparatus (6) upstream of a turbine impeller, wherein each guide vane (7) of the guide apparatus (6) is able to rotate by way of a rotatably mounted guide vane shaft (8), and a turbine housing (3) comprising at least one cooling chamber (5) that is proximate to the exhaust gas inlet, a cooling medium flowing through said chamber. In order to improve the cooling of the guide apparatus (6), it is provided that the bearing (10) of the guide vane shaft (8) is located in an area of the turbine housing (3) that is flushed by the cooling medium.
Abstract:
The invention relates to a method for producing 1,2-propandiol, wherein a flow containing glycerine, in particular a flow produced on an industrial scale during the production of biodiesel, is subjected to low-pressure hydrogenation.
Abstract:
The present invention relates to a process for regenerating a ruthenium catalyst which is suitable for hydrogenation, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity is attained. The process is particularly suitable for ruthenium catalysts which are used for the hydrogenation of aromatics.
Abstract:
The present invention relates to a process for regenerating a ruthenium catalyst for the hydrogenation of phthalates, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity is attained.
Abstract:
A heterogeneous ruthenium catalyst comprises an amorphous silicium dioxide in the form of a support material and is produced by one or several impregnations of the support material with a rhenium salt solution, drying and reduction. Said invention is characterised in that the silicium dioxide support material has a BET surface (according to DIN 66131) ranging from 250 ti 440 m 2 /g, a pore volume (according to DIN 66134) ranging from 0.7 to 1.1 ml/g and a pore diameter (according to DIN 66131) ranging from 6 to 12 nm. The invention also relates to a method for producing a carboxylic aromatic group, in particular a method for producing bisglycidyl ethers of formula (I), wherein R is CH 3 or H, by hydrogenating the core of an aromatic bisglycidyl ether of formula (II) in which the heterogeneous ruthenium catalyst is introduced.
Abstract:
The invention relates to a pump module, a base pump module and a pump system comprising a pump module and a base pump module. The pump module (1) according to the invention comprises a pump channel (5) and a valve chamber (12) connected to the pump channel (5), a fluid being pumpable through the pump channel (5) and the valve chamber (12), a first wall section (13) of the valve chamber (12) being flexible, and the pump module (1) having a mobile valve body (14) that is arranged in the valve chamber (12), the valve body (14) being configured to assume a rest position in which the valve body (14) obturates the valve chamber (12) from the passage of the fluid, and being configured to assume a position of actuation in which the valve body (14) allows the fluid to flow through the valve chamber (12). The valve body (14) can be brought into the position of actuation by way of a deformation of the first wall section (13) to allow the fluid to flow through the valve chamber (12).
Abstract:
The invention relates to an exhaust turbocharger (1), having a turbine housing (2), which comprises an intake connection (3), the intake connection (3) being integrally connected to an exhaust manifold (4), which comprises a single exhaust gas intake (10).
Abstract:
The present invention relates to a microwave plasma deposition process and apparatus for producing diamond, preferably as single crystal diamond (SCD). The process and apparatus enables the production of multiple layers of the diamond by the use of an extending device to increase the length and the volume of a recess in a holder containing a SCD substrate as layers of diamond are deposited. The diamond is used for abrasives, cutting tools, gems, electronic substrates, heat sinks, electrochemical electrodes, windows for high power radiation and electron beams, and detectors.
