Title: Control apparatus
Inventor: GRAHAM RICHARD ALTON
IPC: G01F1/00
Filed: 1961-07-25
Abstract: 963,278. Measuring electrically; valves. JORDAN CONTROLS Inc. July 25, 1961, No. 26863/61. Heading G1N. [Also in Division F2] A valve 48, controlling the flow of fluid through a conduit 49, is adjusted by a motor 12 which also drives the slider of a potentiometer 56, the voltage between the slider and one end of the potentiometer being thus indicative of the angular position of the valve. The motor 12 and the gears coupling it to the shaft 46 of the valve 48, together with the measuring potentiometer 56 are mounted on a plate 3 supported on the shaft 46, rotation of the apparatus being prevented by a torque arm 68 resiliently attached to the conduit 49.

Title: Improvements in or relating to a process for producing mono-alkylbenzenes and the mono-alkylbenzenes resulting from said process
IPC: C07C2/68
Filed: 1947-10-08
Abstract: Mono-alkyl benzenes are prepared by mixing benzene and a gaseous olefin in the presence of a Friedel-Crafts' catalyst at a pressure sufficient to maintain the liquid phase and at a temperature of 100-200 DEG , preferably 150-200 DEG  C., and then passing the product to an evaporation zone at a lower pressure wherein lower boiling constituents are evaporated.  Dry benzene, ethylene and aluminium chloride may be fed to an alkylator, the temperature rising, say, to 163 DEG  C., and the pressure to 100-200, e.g. 150 p.s.i.  The reaction liquor is then passed through an expansion valve to a flash column at about 1 p.s.i., benzene being vaporized, condensed and returned in part as reflux and in part to the alkylator.  The bottoms from the column at about 115 DEG  C. may be in part returned to the alkylator and in part to a separator where catalyst complex is separated and returned to the alkylator, except for a part used to dealkylate the poly-ethyl benzene.  The separated alkylate is cooled to 20-30 DEG  C., and further separated from complex.  Polyethyl benzene, benzene and ethylene, in the presence of complex, are treated in a dealkylator giving a further conversion to ethyl benzene.  Off-gases of the process comprising ethylene, ethyl chloride, hydrogen chloride and some benzene are treated in an absorber with polyethyl benzene prior to feeding the latter to the dealkylator.

Patent GB-806025-A (GB)
Title: Improvements in and relating to the hydrogenolysis of esters
Inventor: BRYSON DOROTHY SHAW TURNER
IPC: C07C29/149
Filed: 1956-09-05
Abstract: A process for the hydrogenolysis of carboxylic acid esters comprises contacting the esters in the presence of hydrogen with a hydrogenolysis catalyst at elevated temperature and pressure under substantially anhydrous conditions.  The esters may be of mono-, di- or poly-carboxylic acids including glycerides of saturated or unsaturated acids and oils and fats containing these; especially suitable are C1-4 alkyl esters of succinic, glutaric and adipic acids.  With these latter esters it is convenient to use hydrogen/liquid ester volume ratios of from 2000:1 to 20,000:1 where the hydrogen volume is measured at atmospheric conditions, temperatures of 180-260 DEG  C., pressures of 150 to 350 atmospheres, and space velocities of liquid ester of the order of 0.1 to 0.3 litres per hour of liquid ester per litre of catalyst-filled space. The ester may be predominantly in the liquid or vapour state under the operating conditions.  The preferred catalyst is a copper/aluminium foraminate catalyst prepared by alkaline dissolution of aluminium from a copper/aluminium alloy which should contain initially 40-80, preferably 50-60, per cent by weight of copper. Examples illustrate the effect on catalyst life of reducing the water content in the reaction zone by preliminary drying of the ester or hydrogen, reducing the hydrogen flow rate, and combinations of these for the hydrogenolysis of dimethyl succinate, glutarate and adipate to methanol and butane-1,4-diol, pentane-1,5-diol, and hexane-1,6-diol respectively.

Title: Improvements in or relating to hormones
IPC: A61K38/24
Filed: 1953-10-06
Abstract: A hormone, free from estron, is prepared by acidifying the urine of a pregnant human or horse with hydrochloric acid, concentrating, dissolving in alcohol, adding an adsorbent, e.g. Japanese acid clay, active carbon, heating, separating, washing the adsorbent with alcohol, drying and extracting with phenolic water at, say, 100 DEG C.

The signals L F <SP>1</SP>, R F <SP>1</SP>, L B <SP>1</SP> and R B <SP>1</SP> from a decoder 34 receiving composite signals (L T , R T ) are fed to loud-speakers via controllable amplifiers 100, 102, 110, 112 and via a.g.c. amplifiers 70-76 to full-wave rectifiers 78-84. The differences between the left and right front and rear channels are taken, 86, 88, rectified, 90, 92, and when above a threshold set by slicers 96, 98 are compared, 94, to generate opposite polarity control signals indicating whether greater leftright separation occurs in the front or rear channel pairs.

To detect conditions concerning these signals, the front signals are added, 150, and differenced, 152, in circuit B to isolate centre signals and their magnitudes compared, 160, to derive further control signals which are added, 106, 116, to the first to accentuate the gain adjustment and which are used to activate FET mixers 170, 172 to mix those two channels containing the lesser or no centre signal to reduce the crosstalk components of the major centre signal in the minor channels.
