Patent GB-513076-A (GB)
Abstract: 513,076. Making emulsions ; sulphuric acid derivatives of polyvinyl compounds. GROVES, W. W. (I.G. Farbenindustrie Akt.-Ges.). March 30, 1938, No. 9725. [Class 1 (i)] [Also in Group IV] Aqueous emulsions, e.g., of minerals or vegetable oils and fats such as paraffin oil or linseed oil, and of polyvinyl compounds, which may be polymerized in emulsified form, are obtained with the aid of a compound prepared by introducing one or several sulphuric acid radicles into a polyvinyl alcohol or a water-soluble derivative thereof. The materials may be emulsified in solution, e.g. in benzene, toluene, esters, &c. The sulphuric acid groups may be introduced by means of sulphonating agents, e.g. sulphuric acid, fuming sulphuric acid, chlorsulphonic acid, or aldehyde-sulphonic acid, or other compound containing a sulpho-group and another active group capable of reacting with the polyvinyl alcohol or derivative such as chlorethane sulphonic acid, benzyl chloride sulphonic acid, and amido-sulphonic acids. The introduction of sulphuric acid residues also occurs when a polyvinyl ester is saponified in the presence of sulphuric acid. Suitable wa,ter-soluble'derivatives of polyvinyl alcohol are those in which a part of the hydroxy groups is acetalized by an aldehyde or ketone such as formaldehyde,. acetaldehyde, propionaldehyde, butyraldehyde,. isobutyraldehyde or cyclohexanone ; or polyvinyl alcohols partly esterified with, for example, formic acid, acetic acid, propionic acid or butyric acid. The corresponding esters may bepartially saponified until they are water-soluble. The agents are particularly useful for the production of dispersions of high molecular polymerization products, e.g., of vinyl acetate, propionate, butyrate, stearate, benzoate ; vinyl' chloride ; styrene ; acrylic acid methyl, ethyl or butyl esters; methacrylic acid methyl,. ethyl or butyl esters or interpolymerization products thereof. The emulsifying agents are used in an amount of 0.5 to 10 per cent. calculated upon the water present. Example (1) describes the polymerization of 100 pts. vinyl acetate at 75‹-80‹C. in the presence of 0.1 pt. formic acid and 0.2 pt. 30 per cent. hydrogen peroxide using first polyvinyl alcohol and then polyvinyl compounds containing sulpho groups prepared in various ways. An emulsion of polyvinyl acetate is also described. The second example describes the preparation of an emulsion of 100 pts. of paraffin oil and 5 pts. of a polyvinyl alcohol, obtained by partially saponifying polyvinyl acetate in alcoholic solution using sulphuric acid, dissolved in 95 pts. of water. Specification 427,494, [Group IV], is referred to.

Abstract: 1,209,776. Tetrahydrocarbon Group IV metal compounds. HOUSTON CHEMICAL CORP. 14 Nov., 1967 [14 Nov., 1966], No. 51659/67. Heading C2J. Tetrahydrocarbon Group IV metal compounds, especially those of tin and lead, and in which at least one hydrocarbon group is methyl, are made by introducing an ether, lithium metal containing at least 0À1% by weight of an alkali metal other than lithium, lead metal and at least one hydrocarbon halide including a methyl halide, to a reaction zone to produce a reaction mass, the hydrocarbon halide being introduced at a rate sufficiently slow to maintain an exothermic reaction until substantially all of the lithium metal has reacted, and recovering the tetrahydrocarbon compounds from the reaction mass. Preferably the reaction is carried out below 60‹ C., and 1À5 to 20 moles of the ether solvent (e.g. an alkyl ether, THF or tetrahydropyran) are used per mole of Group IV metal used, and at least 4À4 moles of lithium are introduced to the reaction zone per mole of lead. The hydrocarbon halide may comprise a methyl halide only but may also contain, e.g. an ethyl halide and/or a vinyl halide; and the alkali metal other than lithium is e.g. sodium. The lead metal may be provided as dry powder or slurried in hydrocarbon halide, and either or both the lead and lithium may be slurried in a diluent, e.g. a liquid hydrocarbon with a normal boiling-point between 90‹ and 150‹ C.

The energy supplied by a motor 4 driving a compressor 3 associated with an air fractionating installation 1 in order to produce a predetermined amount of gas, such as oxygen, at 12 is measured by making a resistor 9 vary in value with the flow-rate of the oxygen produced, and applying across it a voltage derived at a transformer 7 proportional to the motor power input, and measuring the current at 13. This current, being the quotient of the voltage and resistance, and called the "energy factor", equals the energy per unit quantity of oxygen produced. An expansion turbine 2 connected with the installation 1 represents power retrieved from the installation and is fed via a gear-box 5 back to the compressor 3, so that the motor 4 supplies the difference, i.e. the net power input. The oxygen flow is measured at an orifice 11, and the resistor 9 is mechanically varied in accordance with flow-rate by a unit 10. Continuous integration, analogue to digital conversion, and recording of the so-called "energy factor" are mentioned.

The electrical system associated with a portable chain saw driven by an internalcombustion engine 10 comprises a machine 11 which serves as an electric motor for starting the engine and thereafter as a generator driven by the engine for charging a battery 12. To start the engine 10 a button 14 is operated manually to open a decompression valve 15 on the engine, to close a switch 90 and to open a switch 92 to remove the earth on the ignition system 35, 27. Closure of the switch 90 bypasses a diode 106 allowing the machine 11 to be energized from the battery 12, the field windings 50, 51 thereof being energized in the same direction so as to be magnetically aiding, thus giving the machine 11 a high output torque to start the engine. When the engine starts the button 14 is released whereupon it is returned by spring action to a position in which the switch 90 opens, the decompression valve 15 closes but the switch 92 remains in its open position. The machine 11 now functions as a generator to charge the battery 12, the field windings 50, 51 now operating in a magnetically bucking mode. Overcharging of the battery 12 is prevented by an arrangement including Zener diodes 101, 102 sensitive to the terminal voltage of the battery. When the voltage of the battery has reached a predetermined value the Zener diodes apply a signal to the gate electrode 109 of a thyristor 100 which becomes conductive to stop further charging of the battery. To stop the engine 10 the button 14 is operated to close switch 92 thus stopping the engine by earthing the ignition system 35, 27.
