Abstract:
The present solution relates to a coated tablet, comprising the active ingredient solifenacin succinate and the binder hydroxypropyl methyl cellulose, wherein the tablet comprises solifenacin I in the range of 3 to 10% wt. of the solifenacin base and methocel as the binder in the range of 0.5 to 5% wt., related to the core weight, wherein after 3-month stability tests at the 75% relative humidity and 40 °C an increase of the content of the N-oxide impurity of formula II is lower than 0.1% of the HPLC integrated area. Another solutions consist in a pharmaceutical preparation comprising the coated tablet packed in a blister package and a manufacturing method of the coated tablets, wherein a powder mixture containing the active ingredient and the binder is granulated by addition of water, whereafter the granulate is tabletted, the resulting tablets are coated and packed.
Abstract:
A crystalline salt of 2-[(1R)-3-[bis(l-methylethyl)amino]-1-ρhenylρropyl]-4-methyl-phenol with (2R,3R)-2,3-dihydroxybutanedioic acid, known under the name R-tolterodine tartarate, wherein: a) at least 90 % of all crystals are present in a size smaller than 30 μm, b) at least 40 % of crystalline matter are smaller than 250 μm, c) the maximum size of crystals does not exceed 800 μm, d) the salt contains less than 0.1 weight % of the undesirable enantiomer S-tolterodine tartarate, e) analytical test for sulfate ashes (Pharm. Eur.) provides a value lower than 0.1%. The method of its preparation involves at least one crystallization from water. A pharmaceutical composition containing tolterodine or its pharmaceutically acceptable salts further contains a filler, a disintegrant and a lubricant, said composition being free of ions of alkaline earth metals.

Abstract:
Stabilization of the pharmaceutical active solid substance atorvastatin alone or in a mixture with other solid substances embedded in a gaseous mixture is carried out in such a manner that in the surrounding gaseous mixture a partial pressure of oxygen of at most 2 kPa, preferably less than 1 kPa, more preferably less than 0.4 kPa is maintained. The corresponding partial pressure is achieved either by use of oxygen absorbers, by packaging under a pressure of 0.3 - 10 kPa, or by packaging under a slight overpressure of an inert gas, preferably nitrogen, the gas being introduced, by means of nozzles, into the cavities, optionally also into the space of the press roller and of the wiper station.
Abstract:
For film or TV industry , for a camouflage of a background by special effect shots taken in an interior or an exterior or for production of audiovisual or photographic works, there is designed a fabric comprising at least one optically effective textile layer having a thickness of 1 ,5 -12 mm, the layer consisting of a multiple of curved, poly-directionally oriented, in any plane linearly unaligned fibres having a thickness of 50 -200 mu m, provided the fibres occupy from 1 ,5 % up to 20 % of the textile layer volume while a space between the fibres occupies from 80 % up to 98,5 % of the said volume.

Abstract:
Bei einer Scheibenwischanlage an einem Kraftfahrzeug müssen die Enden der Wischerwellen gegenüber dem Aufprall eines Körpers nachgiebig ausgestaltet sein. Um dies zu verwirklichen, wird vorgeschlagen, die Scheibenwischerwellen (5) gegen eine Axialverschiebung in dem aufnehmenden Lagerteil (2) federnd zu sichern, wodurch eine Absorption der Stoßenergie insbesondere bei der Fußgängerkollision mit dem Fahrzeug möglich wird. Die federnde Sicherung umfasst erfindungsgemäß einen Haltering (4), der in einer radialen Nut (10) der Scheibenwischerwelle (5) eingesetzt ist, und an seinem Umfang durch ein federndes Sicherungsmittel (6) radial vorbelastet ist.
