Title: Method for producing stable horse-chestnut seed extracts containing saponin
IPC: C07H15/256
Filed: 1962-02-21
Abstract: A stable horse-chestnut seed extract containing saponin, effective transcutaneously, is prepared by (a) extracting horse-chestnut seed material or (b) dissolving a dry extract of horse-chestnut seed material prepared by known methods, with a polar organic solvent, having a boiling point higher than water, and containing preferably not more than 5 and particularly 3 carbon atoms in the molecule, especially propylene glycol. Anhydrous horse-chestnut seed material may be extracted with anhydrous methanol at below 30 DEG  C. and preferably below 0 DEG  C. and the dry extract remaining after removal of the solvent is dissolved in a mixture of a monohydric alcohol with 2 to 3 carbon atoms and propylene glycol containing 20 to 40% water. Alternatively, dried and degreased horse-chestnut seeds may be extracted with the aforesaid solvent mixture.  Solvent mixtures which may be employed consist of (a) 1,2-propylene glycol, 1,3-butylene glycol, glycerol or beta pyridine carbinol with (b) aliphatic monohydric alcohol containing 2-5 carbon atoms, ketones with 2-5 C atoms and a chloromethane, e.g. methylene chloride or chloroform.  The liquid extracts may be used topically as a cosmetic, e.g. for wrinkled skin, or therapeutic preparation, e.g. for inflammatory conditions, e.g. rheumatism, ulcers and arthritis.

Title: Improvements in or relating to variable inductors for controlling or regulating electric currents in alternating current circuits
IPC: G05B1/02
Filed: 1947-03-11
Abstract: 622,072. Inductances. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., and COURTNEY, T. March 11, 1947, No. 6725. [Class 38 (ii)] A variable inductor comprises at least two windings separated from each other by magnetic shunts so that a variation of the voltage applied. to one winding varies the flux passing through the shunts and thus effects a variation in the reactance of the inductor. A main winding M, connected in the circuit to be controlled, a tapped winding P closely coupled to winding M and an auxiliary winding A are all wound on a core C, the winding A being separated from the other two by the shunts S. As the tapping is moved from No. 1 to No. 2, the opposition flux in the core contained by winding A is reduced, thus reducing the flux in the shunts and air gaps and increasing the reactance of the winding M. Further movement of the tapping point reverses the flux in the core contained by winding A and the shunts and air gaps then carry the difference only between the fluxes in the two parts of the core resulting in a further increase in the reactance of winding M. The limit is reached when there is substantially no flux in the shunts. Air gaps may be introduced into the magnetic circuit to reduce the reactance of winding M. In a further embodiment, windings M, P are combined to function as an autotransformer.
