Title: Procedure for the preparation of very pure 3 alpha-7 beta-dihydroxidolanic acid.
Inventor: BONALDI ANTONIO
IPC: A61K/
Filed: 1994-12-23
Abstract: This is the procedure for preparation of very pure 3 alpha-7 beta-dihydroxycholanic acid from a raw product containing up to 20 percent in weight of 3 alpha-7 alpha-dihydroxycholanic acid and up to 2 percent in weight of 3 alpha-hydroxycolanic acid. The process includes treatment of the raw product with an organic base chosen from triazole, imidazole, pirazole or their derivatives in a medium consisting of a polar organic solvent or a mixture of the solvent with water at boiling point. The product of the reaction is then crystallised by cooling. The crystallised product is dissolved in an acetated mixture of ethyl + water. The acidification to pH 3 crystallisation of 3 alpha-7 beta dihydroxycholanic acid is then obtained by cooling.

Title: Apparatus for conveying humidity or salts
Inventor: MOHORN WILHELM
IPC: E04B1/70
Filed: 1994-03-03
Abstract: In a device for conveying damp or salts, e.g., to dry masonry, with at least one electrical conductor wound into a coil (100) and fitted in a housing, the winding diameter of the coil (100) diminishes spirally from one end to the other. Here the distance between the windings of a spiral or wedge-spiral coil (100) and the coil axis in the inward direction is 40 to 60 % smaller on each full revolution than the previous distance. On average, therefore, this gives: for the spiral radius measured at 90 DEG : R'1 = R1-R2/4; at 180 DEG : R''1 = R1-R2/2; at 270 DEG : R'''1 = R1-R2x3/4; at 360 DEG : R2 = R1/2.
