摘要:
The invention relates to a drive unit for a vehicle and an electric motor that is suitable therefore, comprising a rotor and a stator (1) which is formed by a sheet metal pack (2) and is provided with grooves, at least one winding (3a) being disposed in said grooves (3). The electric motor is penetrated by cooling air. In order to keep production costs low and obtain thermal class 200, the winding (3a) is formed from round wires (7) that are provided with an insulation (12) while the coil heads (4) are embedded in a temperature-resistant elastic material (4a) so as to be protected against external influences.
摘要:
The invention relates to a protective layer (13) for a winding head of an electric machine. Said protective layer consists of a moisture-repellent material that comprises a nanostructured surface (8) once it has been applied to the winding head, resulting in a water contact angle of at least 120 DEG.

摘要:
The disclosure relates to a process for making granulated, hydrated alkali metal orthophosphates. To this end, the disclosure provides for one or more anhydrous or partially hydrated alkali metal orthophosphates presenting a degree of hydration of less than 90%, based on the theoretically possible degree of hydration, and containing an at least 20% proportion of particles with a size of less than 0.045 mm, to be intensively mixed and granulated with water and an ammonium polyphosphate.
摘要:
The present invention relates to the use of molecular markers and related signaling mechanisms for the preclinical and clinical profiling of inhibitors of enzymes having histone deacetylase activity. The invention also relates to the use of such markers as diagnostic and/or prognostic tools for the treatment of tumor patients with such inhibitors.
摘要:
The present invention is directed to compounds of the general formula (I) or pharmaceutical acceptable salts or physiologically functional derivatives thereof wherein: n is a non-aromatic ring system containing two to seven carbon atoms, wherein the ring system can contain one ore two double bonds; X is C, CH or CH2; Y is selected from C, CH, CH2, S, NR, CH2-CH2, H2C—CH, HC—CH2, C—CH2, H2C—C, or C—C; one or more of the hydrogen atoms can optionally be substituted by one or more substituents R′; each of the dotted lines means a single, a double or triple bond with the exclusion of a combination of a triple with triple bond and a double with a triple bond; R′ is independently H, —CN, alkyl, cycloalkyl, aminoalkyl, alkylamino, alkoxy, —OH, —SH, alkylthio, hydroxyalkyl, hydroxyalkylamino, halogene, haloalkyl, haloalkyloxy; R is H, an alkyl or cycloalkyl group; Z is CH, C, or P; p is 0 or 1.
摘要:
The invention provides a process for the production of Maddrell's salt, wherein solid sodium dihydrogen phosphate and/or disodium dihydrogen pyrophosphate, containing catalytic amounts of an acid or of an acid-generating compound statistically distributed therein, is brought to condensation at an elevated temperature.
摘要:
The invention relates to a process for making long chain ammonium polyphosphate consisting essentially of crystalline modification II. To this end, a mixture of phosphorus pentoxide and ammonium orthophosphate in a molar ratio of 1:0.9 to 1:1.1 is reacted with 0.1 to 15 mol % of melamine or its condensation products selected from melam, melem or mellon, calculated as melamine, at a temperature within the range 50.degree. to 150.degree. C. in the presence of an excess of ammonia and the reaction product is heat-treated at temperatures within the range 200.degree. to 400.degree. C.
