Abstract: A battery arrangement has a battery (10, 100, 200) having battery cells (11, 111, 211) with in each case two terminals (12, 112, 212) and a terminal plate (15, 115, 215), on which a terminal (12, 112, 212) of each battery cell (11, 111, 211) is arranged to connect the battery cells (11, 111, 211). A perforated plate (16, 216) is arranged above the terminal plate (15, 115, 215). A cooling medium is sprayed through the holes (17, 217) of the perforated plate (16, 216).

Abstract: A process for the preparation of Rotigotine (1) and of pharmaceutically acceptable salts thereof, which comprises the reductive amination of an amine of formula 6 with the 2-thienylacetic acid-sodium boron hydride complex and which makes use of hydrobromide 5 as an intermediate The process is advantageous from the industrial point of view in that it allows to obtain Rotigotine with high enantiomeric purity starting from optically active 5,6,7, 8-tetrahydro-6-(S)-N-propylamino-1-methoxy-naphthalene (2), avoiding the use of dangerous reactives, the need for difficult chromatographic separation or the formation of by-products. Furthermore, two novel crystalline forms are disclosed.

Abstract: A process for the preparation of valgancyclovir which comprises: a) reacting a compound of formula 7, in an aprotic solvent, in the presence of a condensing agent, with a compound of formula 8, wherein R1, and R2 may be, each independently, hydrogen, an halogen atom or an hydroxyl group; the double bond may either be in the E or Z configuration or a mixture thereof to yield a compound of formula 9 b) mild hydrolysis of compound obtained in a) to give valgancyclovir.
