Abstract: Polyglycol ethers, are produced by reacting 10 to 20 mols of an oxyalkylating agent, such as ethylene oxide, with 1 mol of a product obtained by the addition-reaction between styrene, vinyltoluene, a -methylstyrene or divinylbenzene, and the aromatic nucleus of a phenol or a naphthol.  In Example 3, a mixture of mono-, di-, and tri-a -phenylethylphenol, obtained by reacting 2 mols of styrene with 1 mol of phenol in the presence of sulphuric acid, is reacted at 120 DEG -130 DEG C. with ethylene oxide in the presence of caustic potash, the liquid ethylene oxide (540 parts) being run into the mixture of a -phenylethylphenols while maintaining in the reaction-vessel a gauge-pressure of about 2 atm.  The reaction-product is a water-soluble oil, which may be used to convert water-insoluble pesticides into clear aqueous emulsions (see Group VI).  Other examples relate to the reaction of the ethylene oxide with a -phenylethyl-p-hydroxydiphenyl, di-a -phenylethyl-cresol, mono-a -phenylethyl-naphthol, and di-phenylisopropylphenol.ALSO:Water-insoluble pesticides of the thionophosphoric-O,O-dialkyl-O-p-nitrophenyl ester type are converted into clear aqueous emulsions by means of polyglycol ethers produced by reacting an oxyalkylating agent, such as ethylene oxide, with a product obtained by the addition-reaction between styrene (or a derivative thereof) and the aromatic nucleus of a phenol or a naphthol (see Group IV(b)).

Abstract: 939,716. Automatic control of turbines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 17, 1962 [Sept. 21, 1961], No. 33875/61. Class 38 (4). [Also in Group XXVI] A valve in the steam supply to a turbine is actuated by a velodyne comprising an amplifier and an electric motor driving a tachometer generator providing negative feedback to the amplifier, the motor operating the valve through a gear-box. The input to the amplifier of the velodyne is derived from a differential amplifier which receives a control current and a negative feedback signal from a tachometer generator coupled to the turbine. A transducer connected across the inlet and outlet of the turbine is operated differentially in accordance with the steam pressure across the turbine or part thereof and produces a negative feedback signal which is amplified and applied to the input of the velodyne. The negative feedback in accordance with turbine speed has a slow response to valve movement, whilst the pressure signal has a rapid response and permits a stable control of turbine speed.
