The discs 8 are in electric contact with the shaft 9 which is earthed at 16 but the discs 11 are insulated from one another and the shaft 12, high tension current being supplied thereto by brushes 28 which are connected in groups by wires 35<a>, 35<b>, 35<c> to the secondary windings 36<a>, 36<b>, 36<c> of a Y-wound three phase transformer. Each branch 39 of the wires 35<a>, 35<b>, 35<c> is provided with an inductance 38 acting as an impedance.  High frequency current is supplied by an oscillator 41, the coil 43 of which is connected by wires 45, 46 to the brushes 28, the other end of the coil being earthed at 44.  To prevent the low frequency current from reaching the coil 43, a condenser 47 is inserted in each branch wire 46. Circuits are described for a modification employing a six phase power supply, a modification in which the high frequency oscillation is dispensed with, and a third modification using two electrodes only. In all cases, oil is supplied by a valved pipe 4, a pipe 6 being provided to carry off the gases formed, mainly hydrogen, and the oil carrying the carbon black in suspension.  The supply of oil by the pipe 4 is controlled so that the concentration of carbon black in the reaction chamber is maintained between 5 and 15 per cent, preferably 8 to 10 per cent, this concentration giving the most efficient working.

Filed: 1963-04-11
Abstract: In the process for preparing alkenyl alkali metal compounds by reacting at least one alkyl potassium, alkyl rubidium or alkyl caesium compound, or a mixture thereof, with a terminal or non-terminal alkene containing at least 6 carbon atoms (see Division C2), any unmetalated excess of alkene, being a mixture of isomers of said alkene initially present, is recovered from the reaction mixture.  The alkenyl potassium, rubidium or caesium compounds so produced may be reacted with halobenzenes to produce alkylated benzenes.  Specification 1,008,642 is referred to.ALSO:The invention comprises alkenyl alkali metal compounds, having the alkali metal substituents in the 1- or 3-position in the alkenyl chain, which are prepared by reacting at least one alkyl potassium, alkyl rubidium or alkyl caesium compound, or a mixture thereof, with a terminal or non-terminal alkene containing at least 6 carbon atoms at a temperature below 30 DEG  C., preferably between - 25 DEG  C. and + 20 DEG  C., to produce one or more alkenyl alkali metal derivatives. The alkyl alkali metal compound may contain from 1 to 12 carbon atoms.  The alkene preferably contains less than 25 carbon atoms, e.g. 1-hexene, 1-dodecene, 5-dodecene or 11-tricosene.  The reaction may be carried out in batch, semi-continuous or continuous fashion, preferably in the presence of a saturated hydrocarbon medium.  The alkene is preferably used in molar excess, preferably at least 2 : 1, of the alkali metal compound.  The unmetallated excess of alkene, being a mixture of isomers of the alkene initially present, may be recovered from the reaction medium.  The metallated derivatives can be contacted with an electrophilic reagent to yield a mixture of 1-substituted and 3-substituted alkenyl derivatives; with CO2 the carbonated mixture is acidified to yield a mixture of 1- and 3-substituted monocarboxylic acids; with SO2 and SO3 to produce sulphinic and sulphonic acids respectively; with N-haloamines to produce amines; with epoxides to produce primary alcohols; with aldehydes to produce secondary alcohols; with ketones to produce tertiary alcohols and with a ,b  unsaturated esters to produce monomeric and polymeric condensation products.  The amines may be oxidized to form amine oxides.  Example (1) relates to the reaction between 2-dodecene and n-butyl potassium to give 1-dodecenyl-potassium-3 and 2-dodecenyl potassium-1, which on carbonation give a mixture of 3-indecenoic acid and a -vinyl undecanoic acid.  The alkenylpotassium mixture was also reacted with acetaldehyde to give a mixture of 2-hydroxy-3-vinyl dodecene and 2-hydroxy-4-tetradecene. Reactions carried out as in Example (1) and the acids obtained with different reactants, and varying reaction times, are identified in Table III in Example VII. Specification 1,008,642 is referred to.

Filed: 1946-05-17
Abstract: 625,030. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. May 17, 1946, No. 14966. Convention date, May 19, 1945. [Class 38(iii)] Means for rendering an electro-responsive device, for example a relay, responsive to the load on an induction motor, comprises saturable reactor means subjected to the rotor current of said motor for varying saturation thereof, and affording, as a function of such varying saturation, a varying impedance in a control circuit of said device, said saturable reactor means comprising means substantially suppressing undesired harmonic fluxes in said saturable reactor means, and/or undesired negative sequence saturating fluxes set up when the motor primary is subjected to unbalanced voltages. The suppression of undesired fluxes may be such that the saturable reactor means simulates the impedancevarying action of a saturable reactor supplied with direct saturating current. A relay switch 12 is adapted to operate at a pre-determined value of the rotor current of a three-phase induction motor M, in order, for example, to control transfer ,between sets of motor windings providing different speeds. The rotor' circuit comprises saturable reactors 5, 6, and 7 with variable impedance windings 5b, 6b and 7b which are connected in a single-phase circuit comprising a full-wave rectifier 11 from which the winding of the normally-closed relay is supplied. The reactors are provided with saturating windings 5a, 6a, and 7a, each of which is connected to a rotor phase winding in series with one of the star-connected resistors R1, R2, and R3. The first and other odd harmonic fluxes, except the third and its multiples which are neutralized by means of additional reactors 8, 9, and 10, are suppressed by providing like reactors in each rotor phase. No even harmonics are present unless the reactor cores possess residual magnetism. The third harmonic and its multiples are suppressed by the provisions of impedance coils 8b, 9b and 10b, which are 180 degrees out of phase with-coils 5b, 6b and 7b to which they are connected in series, saturating coils 8a, 9a and 10a being connected in series with coils 5a 6a, and 7a. Undesired negative sequence saturating fluxes, which are set up when the motor stator windings are supplied with unbalanced voltages, are suppressed by the provision of coils 5c-10c, pairs of series-connected coils being interconnected with deltaconnected resistors r<SP>1</SP>, r<SP>2</SP>, and r<SP>3</SP>. In a modification, Fig. 2 (not shown), only three reactors, each having two saturating-coils, are connected in the motor rotor circuit. These coils function selectively for high- and low-speed operation. Each reactor has also two impedance coils.
