Abstract: This invention provides for a compound according to Formula (1), wherein R1 is methyl, ethyl, n-propyl, isopropyl, benzyl or 2-haloethyl and the use thereof in a method to prepare (S)-1-methyl-3-phenylpiperazine by enzymatic hydrolysis of the compound, followed by separation and cleavage of the oxalamic groups, whereby the protease of Streptomyces griseus is used as enzyme for the enzymatic hydrolysis.

Abstract: A stroller is provided having a stroller frame supported by at least one wheel and a handle. The handle includes a brake operator that is coupled to a brake assembly at the wheel. The brake operator is movable between a first position whereby the brake assembly is disengaged from the wheel, and a second position whereby the brake assembly engages the wheel to retard the wheel motion.

Abstract: A stroller handle assembly has a handle with a grip part. The handle is movable from an in-use position extending from the stroller frame to a collapsed position lying adjacent and parallel along the stroller frame. The assembly has a bracket for attaching the handle to the stroller frame. The bracket has one part configured to allow rotation of the handle sideways away from the in-use position to a partly collapsed position. The bracket has a different part configured to allow the handle to rotate to the completely collapsed position adjacent the stroller frame.
