Abstract: A component made of a fiber-reinforced plastic, having a first surface portion, a second surface portion and a transition portion, which is enclosed by the first surface portion and the second surface portion, wherein surface tangents to the first surface portion and the second surface portion are not parallel, at least in regions adjacent to the transition portion. The transition portion has a curvature adjoining the adjacent surface portions in a tangentially constant manner, wherein an arrangement of at least two layers made of a fiber-reinforced plastic extends from the first surface portion, over the transition portion, onto the second surface portion, and fibers at least of one of the layers run with an unchanging orientation on the first surface portion and the second surface portion and, on the transition portion, run in a laterally offset, inflected or curved manner along the running direction.

Abstract: The invention relates to a method for producing large stainless steel meshes on flatbed knitting machines, comprising the steps of providing stainless steel wire and knitting a stainless steel mesh, characterized in that one stainless steel mesh each is knitted on the front and the rear needle bed of the flatbed knitting machine at the same time, and these two stainless steel meshes are linked to each other on one side by connecting stitches.

Abstract: The invention relates to a method for producing noble metal nets on flatbed knitting machines, the steps involving—providing noble metal wire comprising platinum—providing yarn that is combustible or soluble in solvent—knitting two-bed items by simultaneous knitting on the front and rear needle beds and joining the two knitted fabrics by means of connecting pile threads, wherein, on the front or on the rear needle bed, a combustible or soluble yarn is used which is burnt off or dissolved after the knitting process, and a noble metal wire is used on the other needle bed and for the pile threads such that, after the combustible or soluble yarn has been burnt off or dissolved, there remain only the pile threads and the knitted fabric made of noble metal wire and produced on the rear or front needle bed.

Abstract: The invention relates to a precious metal mesh which is knitted on a flat-bed knitting machine, having at least two float stitches per wale, thus having a significantly higher density for a given latch needle density of the flat-bed knitting machine than the precious metal mesh according to the prior art.

Abstract: The invention relates to a wire made of platinum group metals for producing grid catalysts comprising platinum and rhodium. The invention is characterized in that the wire is made as a sheathed wire and consists of a core and one or more sheaths arranged one over the other outwards from the core in a radially symmetrical manner, and the rhodium concentration in the outermost sheath is lower than the rhodium concentration in the sheath or core arranged directly under the outermost sheath.

Abstract: The present invention relates to a method for producing a non-rectangular noble metal net (5) on flat bed knitting machines, comprising the steps of providing noble metal wire or noble metal alloy wire providing combustible yarn knitting a net (5) using noble metal wire or noble metal alloy wire for the reaction zone (7), wherein combustible yam is used for the offcut area (9), which is singed off or otherwise removed after the knitting process.

Abstract: Wire for weaving or knitting a catalyst gauze, said wire being characterized in that it is a stranded wire comprising an assembly of n intertwined filaments, n being an integer with 2?n?8, wherein each of said filaments comprises Pt or a Pt alloy constituted of at least 50% by 5 weight of Pt, said filaments being twisted together over their length so that each of the filaments is wound to at least one other filament.

Abstract: Catalyst gauze (1) for the reduction of the amount of N2O in an ammonia oxidation process, containing a first layer (2) of woven or knitted first wire material (4), whereby said first wire material (4) is made from Pd or a Pd-rich alloy, whereby said first layer (2) contains a reinforcement in the form of a second wire material (5) which is woven or knitted among the first wire material (4) and which has a different composition than the first wire material (5).

Abstract: Methods are provided for the production of bendamustine alkyl ester, bendamustine, as well as derivatives thereof. With the methods the production of these compounds is possible in reproducibly high yields. To this end, hydroxyl-group-containing esters are used as the starting material, whose hydroxyl groups are substituted in a simple way by halogen groups. This substitution is possible in the presence of (i) oxalyl chloride and (ii) dialkylformamide, dialkyl acetamide or dimethyl sulfoxide. In a subsequent reaction, the resulting esters can be hydrolyzed to form the acid.
