Patent GB-1042335-A (GB)
Title: Apparatus for controlling and/or indicating processes for the operation of separating loose solid material
Inventor: HILLYER-RUSS GEOFFREY
IPC: B03B13/00
Filed: 1961-10-09
Abstract: A process for separating loose solid material into a number of fractions according to density measures any two of the quantities weight-rate W, volume-rate V, and bulk density D of the raw feed and thence produces a signal corresponding to the rate of feed of any of the said fractions which is used to control and/or to indicate the operation of the separator.  Where weight rate and volume rate are the quantities measured the derived signal is of the form KaV + KbW where Ka and Kb are constants.  The signals may be used to indicate and/or record the fractions of a particular density in the feed, to indicate when the feed rate of such fractions reaches a particular rate (e.g. the maximum of the fraction that can be handled), to control the feed rate to the process, to control the operations of the process by varying its capacity to handle a particular fraction, to keep the output of a particular fraction within the capacity of ancillary plant, or to control such ancillary plant.  The separator may for example, be a pulsating jig or dense-medium bath.  The initial signals may be measured by electric, mechanical, hydraulic, pneumatic or magnetic means and are combined by known electric or pneumatic means.  Preferably two signals are derived, one representing a rate of feed of a fraction denser than the average of the raw feed, and one representing that of a fraction less dense than the said average.

Title: Process for the production of ketones and carboxylic acids
IPC: C07C29/16
Filed: 1954-12-16
Abstract: Ketones and/or carboxylic acids are prepared by reacting, at elevated pressure and temperature and in the absence of a halide, a hydrocarbon containing olefinic unsaturation, particularly aliphatic olefines, with carbon monoxide in the presence of an aqueous solution of a sulphate of an element of Group 8 of the Periodic System, which solution may further contain a salt of a Group 2 element.  The process is preferably operated in the temperature range 100-220 DEG C., particularly 190-200 DEG  C., and at pressures in the range 150-1000 kg./sq. cm., particularly 200-250 kg./sq. cm., the reaction time being about ten times that for the catalytic addition of water-gas to olefines.  In addition to ketones and carboxylic acids, small amounts of aldehydes, alcohols and esters are formed as byproducts together with carbon dioxide.  In an example, ethylene is passed under pressure (48 atmospheres) into an autoclave containing toluene and an aqueous solution of ferrous, cobaltous and magnesium sulphates, carbon monoxide is then admitted (88 atmospheres) and mixture autoclaved at 192 DEG  C., cooled, more CO admitted (138 atmospheres) and then autoclaved at 197 DEG  C., yielding a mixture of diethyl ketone, propionic acid, and small quantities of propyl propionate, n-propanol and propionaldehyde.
