Abstract: The present invention relates to novel processes for the preparation of optically active 3-aminocarboxylic acids and their esters, in particular processes for the preparation of optically active compounds of the formula IA or IB as free bases or as acid addition salts thereof, in which the radicals are as defined in the description; in particular using the catalytic hydrogenation of olefinic precursors in the presence of platinum on alumina as a catalyst and the removal of chiral auxiliary groups from salt precursors; and novel process sections in the route for their synthesis, and processes for the preparation of biologically, in particular pharmacologically, active compounds, which comprise the novel processes.

Abstract: The invention relates to a process for preparing organosilicon group containing photoinitiators of the formula (I), wherein m is a number from 1 to 200; q is 0 or 1; A is IN-C(O)—O—CHR3—Y— or IN-C(O)—NH—CHR3—Y—; A? is A or R1?; R1 and R1?, R2 and R2? are C1–C18alkyl or phenyl, or —(O)q—SiR1R1?R2; R3 is hydrogen or C1–C6alkyl, Y is a divalent group selected from C1–C10alkeylene, C2–C10alkenylene or —(CH2)b—O—(CH2)a—; and b are each independently of the other a number of 1 to 6; IN is a photolabile functional moiety of the formula (II) or (III), wherein R4 is hydrogen or —C(O)—C(O)—OH or —C(O)—C(O)—OC1–C6alkyl and n is 1–3; R5 and R6 are C1–C12alkyl or together are cycloC5–C7alkyl; R7 is hydroxy, C1–C6alkoxy or morpholinyl; X is —(CH2)a—, —(CH2)b—O—(CH2)a— or —(CH2)b—O—CO—(CH2)a—; a and b are each independently of the other a number of 1 to 6; whereby the process is characterized in that a photolabile functional moiety containing a carboxy group (IN-COOH) or an alkoxycarbonyl group (IN-CO—OC1–C6alkyl) is reacte

Abstract: Apparatus for transporting discrete objects or bulk goods from a first station at a first level to a second station at a second level, which may but need not be above or below the first level, has an endless belt conveyor which is trained about pulleys at the two stations and has an upper reach which is braced from below by a table and defines a straight horizontal or a hilly path for the commodities. The marginal portions of the belt, at least in the region of the upper reach, are guided by pairs of idler rollers whose axes are inclined relative to each other. The rollers are mounted in bearing units which, in turn, are adjustably coupled to elongated bases of a frame.
