Patent DE-3937891-A1 (DE)
Inventor: KRAGL UDO
IPC: C12P19/26
Filed: 1989-11-15
Abstract: N-Acetylneuraminic acid is obtained starting from N-acetylglucosamine in a reactor which contains both N-acylglucosamine 2-epimerase (E.C. 5.1.3.8) for isomerising the GlcNAc into ManNAc, and the N-acetylneuraminate pyruvate-lyase (E.C. 4.1.3.3) able to convert the produced ManNAc with pyruvic acid into Neu5Ac, and into which GlcNAc and Pyr are fed and from whose discharge Neu5Ac is obtained. The process is preferably carried out continuously and, in particular, in an enzyme membrane reactor at pH 7.5 at 25 DEG C, specifically with residence times of from 0.2 to 10 h, and with excess GlcNAc compared with Pyr, which is subsequently metered in where appropriate. The ratio of epimerase and lyase activity in the reactor preferably corresponds to the inverse of the quotient of the reaction rates.

Title: Thermally energising flowing powder - by interacting laser beam undergoing multiple reflections during descent in waveguide
Inventor: OPOWER HANS DIPL PHYS DR
IPC: B23K26/064
Filed: 1990-01-17
Abstract: A stream of powder from a stirred hopper (52) is fed by a worm to the head of an optical wave guide (80) forming part of a unit delivering energy to the powder to cause melting and energy enrichment before the molten material emerges from the wave-guide foot (24) as a cone (40) for application to a substrate (84) or for reaction. Energy is applied to the descending powder from a laser beam (36) taken down the wave-guide after  initial focussing by a lens (34). The wave guide is formed with parallel flat surfaces or a curved zone to cause multiple internal reflections of the beam, enhancing the heating effect. The quite channel wave guide is coated with adhesion-resisting medium. An aperture (62) directing the laser beam may allow passage of a stream (70) of protective medium. In a variation the wave-guide narrows in its downward direction.

Title: Improved operation of three-level pulse inverter - changes voltage of respective strand by current control deviation on reaching tolerance band limit
Inventor: SALAMA SAMIR DR ING
IPC: H02M7/487
Filed: 1990-12-22
Abstract: The potentials of highly dynamic drives are applied cyclically across the switches of the pulse inverter. A current tolerance band regulating method is used, with which the regulating deviations of the phase currents are determined by phase comparators. Additionally, the switches are so changed over, that respectively with the exceeding of a positive or a negative tolerance limit, by a current regulating deviation of a phase, this is fed back again over the applicable potentials of the intermediate circuit DC voltage into the tolerance band. With the reaching or exceeding of the positive (negative) tolerance band limit, by a current regulating deviation of a phase (R), the voltage associated with this phase is increased (reduced) as compared to zero (URO) about a voltage step (Ud/2), or until this is no longer possible. The voltages of the two other phases (e.g. S, T) are lowered (increased) by the voltage step. USE/ADVANTAGE - For three-phase async. machine drive, with stable operation and low-cost control.
