Patent EP-0644949-A1 (EP)
Inventor: CARGANICO GERMANO
IPC: C12P41/00
Filed: 1993-05-26
Abstract: A process for the preparation of optically active S-(+)-2-(3-benzoylphenyl)propionic acid (I), by resolution of the racemate through enantioselective hydrolysis of a reactive ester (II) in an organic medium, which hydrolysis is catalysed by an extracellular lipase of microbial origin. The separation of the resulting free acid from the remaining ester is carried out by extraction in basic medium, to leave the S-ester in the organic phase and the R-acid in the aqueous one. Finally, the desired S isomer is obtained either by aqueous hydrolysis of the remaining reactive S-ester, at constant pH, or enzymatically.

Abstract: A precipitation method is proposed for the preparation of a rare earth phosphate powder by the reaction of a water-soluble salt of the rare earth element in an aqueous solution with an ammonium phosphate, which gives a rare earth phosphate powder consisting of non-agglomerate discrete particles having a spherical particle configuration suitable as a base material of rare earth-based phosphors. The method is characterized by the addition of the ammonium phosphate in the form of a powder to an acidic aqueous solution of the rare earth salt under specified conditions in contrast to the conventional method in which the ammonium phosphate is admixed in the form of an aqueous solution.

IPC: G05B9/03
Filed: 1994-03-16
Abstract: In the case of a safety monitoring system, for protecting devices having normal or enhanced safety for machines (target system) carrying out rotary movements, one dynamic signal (proportional to the rotation speed) and one static signal (0/1) are in each case evaluated for each shaft circuit in order to identify whether the shaft is rotating or is stationary, the contactor-controlled drive current path being enabled only when both signals simultaneously signal that the machine is at rest, in conjunction with the protection device (19) (guard cover, door and the like) being closed. In this case, the static stationary identification signal (L) can be obtained from hardware circuitry in the switching-on contactor current path, as contact-making and, after the target system has been turned off, the static signal content can be stored, in the sense of a turn-off delay for a predetermined time period, or the static stationary identification signal (L) is obtained from an additional rotation speed detection means, by means of proximity switches, in the form of a dynamic signal and is supplied inside the equipment to a frequency-dependent switch.

Abstract: In a tracking or focusing servo control loop (3b, 3c, 41, 20; 3a, 42, 21), there are provided a switch element (6a; 6c) for switch-controlling a tracking or focusing error signal, and a smoothing circuit (7a; 7c) for switching passage the error signal. An amount of detected reflection from an optical recording medium (11) is monitored by a controller section (3b, 3c, 5a, 6b, 7b, 8a; 3a, 5b, 6d, 7d, 8b), and the switching action of the switch element is ON/OFF-controlled by the controller section so as to maintain a servo loop gain at a predetermined standard. Thus, it is possible to maintain a constant servo loop gain without being influenced by variation in the laser light amount or difference in reflectivity characteristics of the recording layers of individual optical recording media, and constantly stable tracking servo control and/or focusing servo control can be performed.
