Patent GB-775835-A (GB)
Title: Preparation of stigmasterol material
IPC: C07J9/00
Filed: 1955-09-28
Abstract: The concentration of stigmasterol material (stigmasterol or its esters) in a phytosterol material concentrate preferably containing between 15 and 90 per cent of stigmasterol material is enhanced by dissolving said concentrate in a solvent (which is a non-polar solvent if the concentration of stigmasterol material in the concentrate is less than 90 per cent) and thereafter selectively crystallizing a phytosterol material fraction enhanced in stigmasterol material.  Suitable non-polar solvents are light mineral oils, petroleum ethers (30-150 DEG C.), hydrocarbons containing from 5-9 carbon atoms, particularly hexane and heptane, toluene, and benzene, ethylidene dichloride, and higher fatty acids and their esters with lower alcohols, e.g. butyl oleate, ethyl palmitate, propyl stearate and methylated fatty acids from soybean oil.  The phytosterol material is normally dissolved in the hot solvent to form a solution containing between 5 and 35 per cent by weight of phytosterol and then cooled to between 20 DEG  and 30 DEG C. (or lower if the material contains esterified phytosterols), after which the crystalline fraction is separated, e.g. by filtration, decantation or centrifuging.  When the initial stigmasterol material content exceeds 90 per cent, polar solvents, particularly acetone, methyl alcohol and isopropyl alcohol, are used.  Detailed examples are provided.

Abstract: 626,135. Changing frequency. STANDARD TELEPHONES & CABLES, Ltd. Sept. 20, 1946, No. 28300. Convention date, May 4, 1945. [Class 38 (ii)] [Also in Group XL (b)] An electromechanical filter which may act as a frequency changer comprises a number of energy storage means, means for supplying the energy from a given source to said storage means successively and at a given cyclic rate, and means for removing the energy from successive storage means at a predetermined cyclic rate. Oscillations from an aerial 1 pass through a transformer 3 connected to a busbar 8 and to a brush 10 moving over contacts 9. Each of the latter is connected to an energy storage means in the form of a condenser 7. An output valve 20 is connected between a further moving brush 18 and bus-bar 8. Incoming oscillations whose frequency corresponds to the rate of revolution of brush 10 or a multiple thereof will build up charges in the condensers whereas oscillations of unrelated frequencies will produce no cumulative effect. The moving brush 18 discharges the condensers and produces outgoing oscillations whose frequency is solely dependent on its rate of rotation, thus permitting the apparatus to produce a frequency changing effect on the signals. Electromagnetically vibrated reeds may be employed instead of the condensers as energy storing means.
