Abstract: A method for preparing a transmission of energy to a vehicle by an inductive charging system, which has a base plate arranged on a primary side of the charging system and a secondary side arranged in or on the vehicle. A first coil is provided in the base plate and a second coil is provided on the secondary side in a vehicle plate. The method includes energizing the second coil provided on the secondary side from a vehicle-based power source and diagnosing the functionality of components arranged on the secondary side of the inductive charging system by evaluating the energization carried out on the secondary side of the inductive charging system. Also disclosed is a device for preparing a transmission of energy to a vehicle by an inductive charging system.

Abstract: The present invention is directed towards novel folate-conjugates of formula I wherein F is a folate or derivative thereof, Z1, Z2, Z3 are independently of each other C or N, S1 to S4 are independently of each other a single bond or a spacer, Ra, Ra?, and Rb are donor groups and/or another group F, Rc is optionally another group F and n is 1 or 2. The invention further contemplates the corresponding metal-chelate complexes as well as pharmaceutical compositions thereof, and their uses in diagnostic imaging and radiotherapy.

Abstract: Process for the production of 6-substituted-4-methyl-2-pyridones having the formula: ##STR1## wherein R is a branched or unbranched alkyl group, a halogenated branched or unbranched alkyl group or a substituted or unsubstituted aryl group. Senecioic acid amide having the formula: ##STR2## is reacted in a solvent at an elevated temperature in the presence of a Lewis acid (as a catalyst) with an acyl chloride having the formula: ##STR3## wherein R has the same meaning as above. The reaction mixture is subsequently placed in an aqueous phase for hydrolysis. The 6-substituted-4-methyl-2-pyridone is separated by extraction through the buffering of the reaction mixture at a pH of 4 to 5.
