Title: Improvements in or relating to the selective extraction of basic and/or acidic substances from plant solids
IPC: A24B15/24
Filed: 1966-03-10
Abstract: Basic and/or acidic substances are removed from plant solids by extracting the plant solids with an organic solvent which is not miscible with water to an unlimited extent, extracting the charged organic solvent with an aqueous solution of acidic or basic substances obtained from the plant solids, and separating the substance to be removed from the charged aqueous solution by ion exchange.  The organic solvent is circulated by a device 1 through a solid-liquid extractor 2 where nicotine is extracted.  The solvent is then passed to a liquid-liquid extractor 3 where it is contacted with the aqueous solution which is circulated by a device 4 through an ion exchange container 5.  Recirculation of the solvents ensures their saturation with soluble constituents which it is not desired to remove so that when this stage is reached those constituents are no <PICT:1080639/C2/1> longer removed from the tobacco.  Suitable organic solvents are, e.g. ketones such as butanone and cyclohexanone, esters such as methyl, ethyl and butyl acetate, and certain ethers, hydrocarbons, halogenated hydrocarbons and alcohols. Mixtures of such solvents may also be used.  The process may be used for removing ascorbic acid from dried rose hips. Quantitative examples are given.

Abstract: 679,681. Rotary conveyers. CORNING GLASS WORKS. May 1, 1950. [May 7, 1949] No. 10691/50. Class 78 (i). [Also in Groups XI and XXIII] A rotary conveyer, for use in severing glass articles by burning, comprises a chuck 23 with a path of travel through at least two zones, a vacuum pipe 73 connected to the chuck and normally closed by a valve, means to hold the valve open while the chuck is travelling through the first zone, and independent means to hold the valve open during travel through the second zone when the chuck is carrying an article. In the preferred embodiment, a number of chucks 23, Fig. 1, are mounted on a turret 21 secured to a shaft 12 driven by reduction gearing from a shaft 15. Each chuck is connected by a pipe 73 with a control valve 51 bolted to a vacuum chamber 31 which is also carried by the shaft 12. A chamber 55 in each valve 51, Fig. 6, is connected to the atmosphere through a port 71 when the valve is closed so that there is no reduction of pressure in the chuck. Displacement of the valve spindle 59 by a cam 80 to the position shown closes the port 71 and places the chamber 55 in communication with the chamber 31 through an intermediate valve chamber 53 so that a reduction in pressure is obtained in the chuck and an article may be placed therein. This reduction in pressure is communicated by a pipe 76 to a chamber 75 so that a diaphragm 78 is deflected to hold the valve open against the pressure of its return spring 60 when the rise on the cam 80 has been passed. If no article has been placed in the chuck the valve closes. A portion of the profile of the cam 80 positively closes the valve when the chuck reaches the position at which the article is to be released. The cam 80 is resiliently mounted and acts on the valve spindle through a resiliently mounted roller 79. Specification 679,709, [Group XXIII], is referred to.
