Title: Improvements in or relating to the preparation of concentrated extracts of active physiological principles from liver tissue
IPC: A61K31/00
Filed: 1932-04-28
Abstract: The anti-an mic principle, the physiologically active substance or hormone known as physin, and meat extracts for flavouring &c. are extracted from liver, or aqueous solutions or suspensions obtained from liver, or from liver digested by ferments, by treating the material with alcohol of concentration increasing progressively up to 90 per cent and treating the extract soluble in 90 per cent alcohol with acetone.  Liver to be extracted is preferably digested, e.g. with papain, and the liquid product evaporated to a paste to which sufficient alcohol is added to give an alcoholic content of 60 per cent, the mixture being allowed to stand and then filtered.  The precipitate is a meat extract or base for soups, gravies, &c.  To the filtrate is added alcohol sufficient to give a concentration of 90 per cent and filtered, the residue being redissolved in water and again precipitated with 90 per cent alcohol.  This precipitate contains the anti-an mic principle.  The combined filtrate is then freed from alcohol by distillation and taken up in water.  It contains all the physin which may be further concentrated by adding acetone up to 90 per cent.  The filtrates from acetone treatment are evaporated to dryness or small bulk and constitute the final concentrate of physin.  The residue from the acetone treatment is a meat-flavouring extract.  When preparing anti-an mia extract by the known method employing a mixture of alcohol and acid followed by dehydration alcohol for extracting liver after evaporation of the alcohol, the residue is washed with water and contains most of the physin.  This residue may be further treated with acetone as above described.

Filed: 1937-04-29
Abstract: 494,688. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 29, 1937, No. 12260. Convention date, April 29, 1936. [Class 40 (v)] For the reduction of interference noises in an audio-frequency amplifier the high frequency signal components are first accentuated, after which signals of above a predetermined amplitude are suppressed and finally the balance between high and low frequencies is restored. As shown the high frequency components of signals from an input stage 13 are accentuated by passing a capacity 14, the output from the next valve 15 consisting for each incoming impulse such as 11 of two oppositely directed impulses. If these impulses are above a predetermined amplitude one is absorbed by the shunt valve 30 normally biassed to cut-off and the other after phase reversal in the stage 19 is absorbed by the valve 37. The signal output is amplified by the valves 23, 27 between which is connected a network 24, 25, 26 which restores the balance of upper and lower frequencies. In another embodiment, Fig. 2 (not shown), a single limiting valve is used with a low anode voltage and suppresses noise impulses of opposite polarity by virtue of plate current cut-off and plate voltage saturation respectively.
