Title: A method of continuously producing barium hydroxide
Inventor: KEMENY GIULIO
IPC: C01F11/10
Filed: 1969-09-10
Abstract: 1277046 Barium hydroxide KALI-CHEMIE AG 10 Sept 1969 [11 Sept 1968 12 Sept 1968 13 Feb 1969] 44664/69 Heading C1A Barium hydroxide is produced continuously by oxidizing a barium sulphide liquor at 45-80‹ C. in several consecutive but separate zones with an oxygen-containing gas (e.g. air, or air enriched with oxygen) continuously withdrawing the resulting turbid liquor when less than half of the BaS initially present has been oxidized, removing the substances responsible for the turbidity of the liquor and crystallizing out the barium hydroxide. The apparatus may consist of several consecutive stirred reaction vessels, into which air is introduced, or an oxidation column with stirring containing obstructions and/or stirring devices for mixing the air with process liquor. The air should preferably be passed countercurrent to the process liquor. In order to suppress foaming a flocculating agent may be added, a preferred agent being based on polyacrylic acid and its derivatives. The mole ratio of total sulphur, to sulphur bound as monosulphide should be in the range of 1À2 to 2À0, preferably between 1À6 and 1À8. If the mole ratio of total sulphur to sulphur bound as monosulphide is between 1À2 and 1À5 then the oxidation temperature should be between 65‹ and 80‹ C., 68‹ to 75‹ C. preferred, and if this ratio is between 1À6 and 1À9 the temperature should be between 45‹ and 60‹ C., 48‹ to 53‹ C. preferred. The crude barium hydroxide may be further oxidized at a temperature of between 70‹ and 95‹ C., 65‹ to 90‹ C. preferred, and after removing the sparingly soluble barium compounds thus formed, recrystallized. The mother liquor may then be further oxidized at a temperature of between 65‹ and 90‹ C., 70‹ to 80‹ C. preferred, and re-used for dissolving fresh barium hydroxide. The oxidation of the mother liquor should be stopped when the BaS content falls below 0À15%, and preferably when it falls to between 0À08 and 0À10%. If the oxidation is continued beyond the point when half the sulphide is oxidized then BaSO 3  and BaS 2 O 3  are formed.

Filed: 1963-11-18
Abstract: 1,027,607. Control of A.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 12, 1964 [Nov. 18, 1963], No. 45438/63. Heading H2J. [Also in Division G1] .. The displacement of a motor FM is measured by integrating the output of a tachogenerator TG coupled to the motor. As shown for controlling the feed motor of a planing machine, cutting is initiated by push-button switch " ON," which energizes the supply contactor FD through switching devices FPR, which cut-off after a preset number of feeds, AR1 which is opened at the end of a forward stroke and recloses at the end of the return stroke, and FCS which energizes an amplifier FCA feeding contactor FD during the cutting stroke. When the displacement as measured is equal to that preset on a potentiometer PS, a signal from circuit VD is applied to AR1 to switch off the contactor FD and disconnect motor FM from the supply. Simultaneously, a brake switch device BM energizes braking contactor B through amplifier BA to connect the motor stator via a delta connection of capacitors CD to a D.C. braking supply. Contactor B is restored to normal after a period determined by timing device BMT. A further timing device FRT produces a signal similar to that from circuit VD if the latter fails to do so in a given time.

Title: Improvements in or relating to a process and apparatus for the manufacture of polycrystalline metal whiskers and the products thereof
IPC: C23C16/455
Filed: 1965-10-28
Abstract: Polycrystalline metal whiskers are made by feeding carbonyl of ferromagnetic metals (such as Fe, Co or Ni) into an oxygen free decomposition chamber so as to give 10-4 to 10-10 moles per c.c. of the chamber, against a falling temperature gradient, the metal atoms produced forming chain like aggregates under the influence of a magnetic field.  Further carbonyl vapours of ferro- or paramagnetic (such as Mo or W) metals are then fed through the chamber with the temperature of the chains being kept sufficient for coherent deposition of the metals until the whiskers are of the desired thickness.  The carbonyl supplied to the vapourizer may be liquid or as a solid carried in an inert solvent.  Non metals or metal compounds may be included in the carbonyl vapour for deposition on the chains simultaneously with the metal.  Oxidation, carburization or nitration of the metals can be carried out simultaneously with the deposition of the metal or in between successive layers thereof.  The fibres produced by the method of the invention may be cold rolled, cold pressed or cold welded and sintered.

Said means includes samplying circuits for producing D.C. signals representative of signal peak amplitudes, and means for comparing the two D.C. signals. As described, a direction finder includes two crossed loop aerials 10, 12 and a dipole aerial 14. Each aerial feeds into a respective R.F. amplifier/ mixer 16 followed by an I.F. amplifier 20. The mixers all receive second inputs from a common local oscillator 18. The I.F. amplifiers associated with the loop aerials have a common AGC unit 29, to enable their gains to be matched. The I.F. amplifier associated with the dipole aerial feeds into a phase discriminator 21 which is connected in the feedback loop of a voltage controlled oscillator 23, and serves to lock the frequency and phase of said oscillator in correspondence with the signal received by the aerial 14. The oscillator 23 provides two signals which are in phase quadrature with one another, and each of said signals is used to control an electronic sampling switch 22a and as input to a modulator 24. The sampling switches 22a operate on the output signals from the I.F. amplifiers 20 associated with the loop aerials 10, 12 and reservoir capacitors 22b give D.C. voltages representative of the amplitudes of those signals, which are fed to the modulating inputs of the modulators 24. The outputs of said modulators, which are in phase quadrature, are added in an adder 26, and the relative phase of the resultant, which indicates without ambiguity the direction of incidence of the received radio waves, is determined by a phase comparator 28 with reference to a second input thereto, from the oscillator 23.

Organolithium compounds are prepared by reacting: (a) a C 1 -C 15  organolithium compound; (b) an organic amine, phosphine sulphide, halide, an ether, ferrocene or a cyclopropyllic compound (as defined below) and (c) a chelating bifunctional Lewis base having the formula wherein R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP> and R<SP>4</SP> are C 1 -C 3  alkyl radicals and X is a C 4 -C 7  cycloalkylene or a C 1 -C 4  alkylene radical having 0 to 4 monovalent hydrocarbon radicals of 1 to 20 carbon atoms as substituents, the organo portion of (a) being such as to form a weaker protonic acid than (b), and (b) being a stronger protonio acid than (b). The product is the compound (b) metallated, and chelated by the base (c). The C 1 -C 15  organolithium compound may be alkyl, cycloalkyl, aryl or aralkyl, e.g. methyllithium, butyllithium, cyclooctyllithium, dodecyllithium, 2-methylbutyllithium, phenyllithium, benzyllithium, sec.-butyllithium, allyllithium or vinyllithium. The cyclopropyllic compounds which may be used have the formula where R is hydrogen or C 1 -C 10  alkyl or cycloalkyl, there being at least 4 hydrogen atoms on the cyclopropane ring. Cyclopropane is preferred. Many examples of suitable chelating bases are given, N,N,N<SP>1</SP>,N<SP>1</SP>-tetramethyl. 1,2- ethanediamine (TMEDA) being preferred. The reaction may be carried out in a hydrocarbon diluent or in an excess of the compound being metallated, if liquid. The molar ratio of organolithium compound to chelating base may be 100:1 to 1:10 and the chelating base may be removed from the product by treatment with lithium salts or Lewis acids. Examples describe the reaction of butyl lithium with (1) ferrocene and (2) cyclopropane in the presence of TMEDA yielding complexes of the latter with Li ferrocene and Li cyclopropane respectively, and (3) the reactions of phenyl lithium with pyridine and beta-picoline using TMEDA as base. The products of (1), (2) and (3) are carbonated, yielding ferrocene, cyclopropane, pyridine and picoline carboxylic acids. Data is given comparing the metallation of benzene by butyl lithium in the presence of various di-tertiary amines. It is stated that organolithium compounds may also be prepared by reacting an organic chloride, e.g. phenyl chloride, with Na metal and LiCl in the presence of the chelating base or by reacting an organo halide, e.g. vinyl or phenyl chloride with Li alone or with Na, in the presence of the base, an inert hydrocarbon diluent being present in both cases.
