| 20090142809 | Method for Cleaving Cervimycin Monoesters - The invention relates to a method for cleaving cervimycin esters. An object of the invention to convert in a simple manner the cervimycin esters which are less active but formed in larger quantity into the highly active cervimycin K that occurs as a minor component in the preparation by fermentation, is achieved by preparing unesterified cervimycins from cervimycin esters with di- or monomethylated malonic acids, by ester cleavage effected by at least one esterolytic enzyme at temperatures of 20° C. to 75° C. and a pH of pH 5.0 to 10.0, preferably pH 6.0 to 9.0. | 06-04-2009 |
| 20090209013 | Burkholderia rhizoxina micro-organisms, novel endosymbionts of rhizopus sp. and method for producing rhizoxin and/or rhizoxin-derivates using said micro-organisms - The invention relates to a method for producing rhizoxin and derivates of rhizoxin. | 08-20-2009 |

| 20080216795 | Engine braking method for an internal combustion engine having two serially arranged exhaust-gas turbochargers - In an engine braking method and an internal combustion engine including an engine braking arrangement, wherein the engine has high pressure and low pressure exhaust gas turbochargers connected in series, with a bypass ( | 09-11-2008 |
| 20090013689 | Compressor for an internal combustion engine - In a compressor of a turbocharger of an internal combustion engine comprising a housing with an inflow channel; a compressor impeller arranged in the inflow channel; and a bypass channel which has a first flow opening upstream of the compressor impeller inlet, a second flow opening downstream of the compressor impeller inlet and an axial annular chamber which connects the first and the second flow openings. An axial vane structure is provided in the axial annular chamber of the bypass channel, which imparts a swirl direction corresponding to that of the air mass flow in the inflow channel to the air mass flowing through the bypass channel from the second to the first flow opening. | 01-15-2009 |
| 20100310364 | Turbine housing and method for producing a turbine housing - In a turbine housing, for an exhaust gas turbocharger of an internal combustion engine with an exhaust gas guide section which has at least one spiral channel that can be coupled to an exhaust path of an exhaust tract and a reception chamber for accommodating a turbine wheel arranged downstream of the at least one spiral channel, at least one first and one second partial housing are provided, which include complementary wall regions of the at least one spiral channel and which are joined so as to form the at least one spiral channel. Also, an exhaust gas turbocharger with such a turbine housing is provided and a method for producing such a turbine housing. | 12-09-2010 |

| 20090038781 | Heat Exchange System - The invention relates to a heat exchange system for electronic devices, preferably data processing devices, comprising high-performance processors or having a high processor density. The heat exchange system comprises essentially a primary cooling circuit and a secondary cooling circuit both being thermally associated to the one or more processor unit(s). The secondary cooling circuit is configured as a completely closed system, the coolant in the secondary cooling circuit being driven exclusively by mechanical or inductive coupling with the flow drive of the primary cooling circuit | 02-12-2009 |

| 20090304369 | DRIVE AND EVALUATION UNIT - The invention relates to a drive and evaluation unit for displacing an object to be displaced, particularly for raising and lowering a side window in a motor vehicle. The drive includes a commutator motor with a stator having two diametrically opposed permanent magnets. The magnets have cross-sectional shapes of a respective peripheral contour segment, having a radial inner peripheral contour segment which encompasses an armature over a respective inner peripheral angle. The armature is provided with ten grooves spaced around its periphery for holding armature windings that are configured as lap windings. The evaluation unit includes a device for determining the rotational position of the armature by evaluating the ripple count of the armature current. According to the invention, the armature windings are configured as short pitch windings, and the inner peripheral angle of the radial inner peripheral contour segment of at least one of the magnets is between 101° and 111°. | 12-10-2009 |
