Abstract: ABSTRACT          EVAPORATOR FOR VACUUM WEB COATING    An evaporator for generating vapour for deposition as a coating on a web substrate in a vacuum web coating process comprises evaporation means having vapour outlet means through which coating material is conveyed from the evaporation means and deposited on the substrate.   The evaporation means further comprises means whereby an inert gas  may  be  fed  to  the  evaporation  means  to  quench evaporation of the material and/or to cool the evaporation means.  The evaporation may thereby be halted rapidly to allow replacement of  the  substrate  and/or the  coating material.  The inert gas may advantageously be recirculated through refrigeration means and some or all of the inert gas may be 'back-fed' into the evaporation means through the vapour outlet means.      The  apparatus  enables  the  stoppage  times  in  the coating process to be significantly reduced.

IPC: C07D493/04
Filed: 1993-09-29
Abstract: A process for preparing crystalline, anhydrous podophyllotoxin compound (1) from a podophyllotoxin product comprises dissolving the product in a non-aromatic and non-halogenated solvent which has a boiling point at atmospheric pressure not ex-ceeding 130 °C, and which contains at the most about 1 % v/v of water, cooling the solution to precipitate crystals of podophyllo-toxin, isolating the crystals and drying them at a temperature which during the drying procedure is increased but is always such that it is below the temperature at which the crystals sinter or melt, the drying being continued until the melting point is in a range of 183-184 °C and the residual amount of solvent is at the most 500 ppm. When the starting material contains complexed or ad-sorbed organic solvent, an initial azeotropic evaporation treatment is performed to remove this solvent. The yield of pure podo-phyllotoxin is greatly increased by adding water to the crystallization mixture.

Patent CA-2147772-A1 (CA)
Inventor: LEE CHIN-HUI
IPC: G10L15/02
Filed: 1995-04-25
Abstract: Disclosed is a method for drastically reducing the average error rate for signals under mismatched conditions. The method takes a signal (e.g, speech signal) and a set of stored representations (e.g, stored representations of keyword) and performs at least one transformation that results in the signal more closely emulating the stored representations. This is accomplished by using one of three techniques.  First, one may transform the signal so that the signal may be better approximated by (e.g, is closer to) one of the stored representations.  Second, one may transform the set of stored representations so that one of the stored representations better approximates the signal. Third, one may transform both the signal and the set of stored representations.
