Title: Improvements in or relating to a method of separating tar acids and tar bases
Inventor: NEUWORTH MARTIN BRANDT
IPC: C07C37/82
Filed: 1952-06-26
Abstract: Tar acids and tar bases are separated by contacting a solution of a mixture of the acids and bases in a polar solvent with a cation exchange resin, whereby the bases are adsorbed, recovering the tar acids and regenerating the resin by treating with an acid in a polar solvent for the bases.  The method is suitable for separating the mixtures of tar acids and tar bases derived from low temperature coal tar distillates and particularly for mixtures p  wherein the tar bases boil at above 200 DEG  C.  The polar solvents used are preferably aqueous organic solvents, e.g. methanol, ethanol, propanol, acetone or methyl ethyl ketone.  The preferred cation exchange resins are those containing acidic groups especially sulphonic groups such as the sulphonated phenolic, sulphonated styrene or sulphonated coal resins.  Examples are given of the separation of acids and bases from a solution of coal tar in aqueous methanol by sulphonated coal or sulphonated phenolic resins followed by regeneration of the resin by hydrochloric acid in aqueous methanol.

Abstract: 1,088,515. Piano accordion. FARFISA S.p.A. April 15, 1965 [May 16, 1964; Feb. 19, 1965], No. 16207/65. Heading G5J. Movement of the bellows of a piano accordion is used to generate an electric signal which may be used to control the volume and timbre of an associated electrophonic instrument. In the arrangement shown a plate fixed to one end of the bellows carries on its underside three photoresistors each located below a rhombic shaped hole in the plate. Movement of the bellows rotates a further plate 6 which carries three similar holes so as to vary the overlap of the two sets of holes. The amount of light passing through the holes from three fixed lamps 22 is thus varied so that the signal produced by the photo-resistors is varied. Helical spring 17 tends to restore the device to its mean position where a spring-loaded detent 19 locates it. In another embodiment (Figs. 4-6, not shown), spring 19 is replaced by oppositely acting springs on each side of a piston in a cylinder and the rotating plate carries teeth which engage gear-wheels to rotate potentiometers while in still further arrangements the central electrode of a differential capacitor is used. An arrangement which provides a signal increasing in one direction only is also described (Figs. 10-12, not shown).
