  • Bevel gear transmission
    Patent number: 9032826
    Abstract: A bevel gear drive (1) comprises a spur bevel gear (2) and a pinion which both mesh with one another. The spur bevel gear and the pinion are arranged within a housing (3). An abutment plate (4) is provided so as to avoid displacement of the spur bevel gear (2), under high operating loads. The abutment plate (4) is integrated in the housing (3) and supports the spur bevel gear (2) when forces, that can cause displacement of the spur bevel gear (2), act upon the spur bevel gear (2).
    Type: Grant

  • Process for the hydrogenation of C—C double bonds
    Patent number: 7094905
    Abstract: The present invention relates to a gentle process for catalytic hydrogenation and to a process for the preparation of biotin using the hydrogenation step. The process according to the invention for the selective, catalytic hydrogenation of a C—C double bond on a thiazole ring system having at least one functional group which can be converted into a salt under basic conditions is characterised in that the hydrogenation is carried out in a protic solvent is a pH>7.
