Patent DE-4140185-A1 (DE)
Inventor: WUNDERLICH JENS-CHRISTIAN
IPC: A61K9/10
Filed: 1991-12-05
Abstract: Immediate-effect medicaments containing a pharmacologically active 2-arylpropionic acid derivate as a pharmaceutically applicable nanosol have a considerably improved action start and bioavailability of the active substance. The 2-arylpropionic acid derivates, for example ibuprofen, flurbiprofen and ketoprofen, that are scarcely soluble in an aqueous medium, are present in a gelatine-stabilised nanosol in a form that allows these active substances to be quickly and completely resorbed already in the stomach. The disclosed colloidal disperse system composed of a 2-arylpropionic acid derivate is prepared by selecting a gelatine or gelatine derivate according to their isoelectric point (IEP), so that their IEP is adapted to the charge of the 2-arylpropionic acid derivate particles, leading to a neutral charge when the gelatine or its derivate is combined with the undissolved 2-arylpropionic acid derivate at a determined pH value. The gelatine or its derivate are converted into an aqueous sol form, their pH value is set according to the IEP of the gelatine at a value that stabilises the nanoparticles of 2-arylpropionic acid derivate at an approximately or totally neutral charge. Before or after said last step, the 2-arylpropionic acid derivate is dissolved in the aqueous gelatine sol or a solution of 2-arylpriopionic acid derivate is blended with the aqueous gelatine sol.

Inventor: PHILLIP GUENTHER DR
IPC: C22F1/08
Filed: 1992-08-21
Abstract: A process and device are disclosed for regulating the annealing power in at least one annealing section of a continuous annealing and processing line for continuously cast metal products. The speed of the cast products (D) passing through the continuous annealing device is detected, as well as the voltage currently applied to the annealing section, which is converted into an effective value (Ue) by means of a control device (50). The voltage supplied to the annealing section is modified by a control signal derived from the determined effective value of the voltage, in order to achieve a predetermined annealing power value dependent on the measured speed. At least the current flowing in one annealing section is also detected and converted into an effective value. The annealing power actually supplied to the annealing section is calculated from said effective values.
