Title: Improvements in or relating to lubricating oils
IPC: C10M159/14
Filed: 1932-12-12
Abstract: Hydrocarbon lubricating oils are improved in colour, viscosity, and setting point by addition of a small proportion, e.g. 0,2--1,0 per cent of a resinous product of the condensation or polymerization, in presence of a condensing agent, of hard or soft paraffin or similar waxes mixed or not with cyclic hydrocarbons. The waxes may first be chlorinated.  10--60 per cent relative to wax of aluminium chloride, zinc chloride, or boron fluoride may be used as the catalyst, preferably mixed with halides of the first and second groups, e.g. NaCl, NaBr, KCl, CaCl2, CuCl2, HgCl2 which diminish the action of the catalysts; 10--70 per cent of napthalene or other polynuclear aromatic hydrocarbon is preferably present; and the reaction temperature is usually between 20 and 200 DEG  C.  For example, 1 kg. of chlorinated paraffin wax containing 20 per cent of chlorine is condensed for 5 hr. with 1 kg. of naphthalene in presence of 0,4 kg. of aluminium chloride and 1,5 kg. of a 180--280 DEG  C. paraffin oil diluent, the temperature being raised gradually from 30 to 160 DEG C.  The product is stirred at 80 DEG  C. with water, separated from solids and water, freed from diluent by distillation, dissolved in heavy benzine, refined by treatment at 50 DEG C. with 2 per cent of aluminium chloride, filtered from solid hydrocarbons, and freed from benzine by distillation.  1,7 kg. of resinous product remains.  It is added in the proportion of 0,2 per cent to a lubricating oil obtained by destructive hydrogenation.  Specification 349,071 is referred to.

Title: Vibratory apparatus
IPC: B23K20/10
Filed: 1962-06-22
Abstract: 1,009,623. Extrusion; welding by pressure. AEROPROJECTS Inc. June 22, 1962 [June 28, 1961], No. 24198/62. Headings B3P and B3R. [Also in Division H4] A coupling member in an ultrasonic welding or extrusion apparatus comprises a plurality of flexible wires or ribbons. A piezo-electric or magneto-strictive transducer 12 (Fig. 1) is carried in a mount 26 of the type described in Specification 877,966 [Group XXXIX] and has metallurgically attached thereto a coupling member 20, 36. The ribbons 58 which may be made of " Monel " (Registered Trade Mark) are metallurgically secured at one end in a notch 38 of the coupler and at their other ends in tangential slots 56 (Fig. 2) or radial slots (Fig. 7) of a flange 54 (Fig. 1) integral with a probe 46 which, in conjunction with work-holder 44, serves to weld together metal plates 40, 42. A mathematical discussion of the calculation of the wavelength of vibrations in the ribbons in terms of the radius of curvature and the crosssectional dimensions of the ribbons is given in the Specification from which it transpires that all of the ribbons should be either an odd or an even number of half-wavelengths long although due to the different wavelengths in ribbons having different radii of curvature their actual physical length will not in general be the same. The position (in terms of wavelength) of the flange 54 relative to the free or working end 53 of probe 46 and the part 52 thereof where it enters a massive block 48, in conjunction with the method of attachment of ribbons 58 to the flange, governs the type of vibration, e.g. torsional or longitudinal &c. of the probe and all these factors are discussed. In an extrusion apparatus (Fig. 8) the ribbons 86 are attached to an end face of a hollow cone-shaped container 92 which has a disc 110 screwed into the bottom part thereof. A cylinder 104 containing a ram 108 is located above chamber 112 which contains the material to be extruded. Specification 895,403 is referred to.

Title: Improvements in apparatus for the measurement of the capacitance and power factor of electrical condensers
IPC: G01R17/00
Filed: 1928-08-23
Abstract: 317,642. Campbell, A. Aug. 23, 1928. Capacities and power-factors, measuring; sets of resistances and inductances.-Capacitance and condenser power factor are measured by means of a modified Care Foster bridge in which no external resistance is added in the arm containing the condenser under test. As shown in Fig. 2, the four arms of the bridge include resistances P, Q, R, s, self-inductances L, l, a mutual inductance M, and the condenser C to be tested, of which s represents the internal losses. For small power-factors balance is obtained by adjusting the resistances P, Q, R. For large power-factors the inductances L, l may be adjusted. The resistance Q may be calibrated to read the power-factor directly. If the resistance P is kept constant, the capacitance C is proportional to the reciprocal of the resistance R, which may be arranged as a conductance box so as to be direct reading. In the modification shown in Fig. 3 the resistance Q is formed as a slide wire with its zero at E, the portion H corresponding to negative values. A small variable resistance JX may be included to compensate for the variation of the arm R. In a further modification the arm Q is dispensed with and balance is obtained by 'varying one or both of the resistances P, R and also one or both of the inductances L, l, In order to permit continuous variation of the inductance l from negative values through zero to its maximum positive value a variable self-inductance of constant resistance X, Fig. 2, is included in the arm R and is shown in Fig. 6. Two inductances a, b are arranged at right angles so as to have no mutual inductance, or they may consist of toroidal windings or by winding each set of sections on a pair of equal bobbins in opposite directions so as to be astatic. The inductances a, b have tappings brought to stud switches A, B through sets of resistances p, q of such values that the resistance of the whole circuit is constant for all positions of the switch arms. Alternatively the sections a, b may consist of sets of independent coils connected together at one end and having their other ends connected to the studs. A fixed inductance and a slide wire r are arranged in series with the coils a, b, a variable portion of the slide wire r being shunted by a condenser k. The slide wire r may be calibrated to read self-inductance directly. For high sensitivity the detecting instrument may be connected to the bridge through a thermionic valve amplifier. The positions of the detecting instrument and the source may be interchanged.

Title: Organopolysiloxane emulsions
IPC: C08G77/46
Filed: 1964-06-11
Abstract: The reaction product of a polyethersiloxane which is stable to hydrolysis and contains a -->COH group, and a polyisocyanate, is used as an emulsifier for making aqueous emulsions of siloxane liquids or resins.  The emulsifier can be made by reacting, e.g. a methylhydrogen-siloxane with an olefinic epoxide and reacting the resulting epoxy-organosiloxane with a polyalkyleneglycol monoalkyl-ether, optionally in solution in a hydrocarbon solvent and in the presence of BF3 or KOH as catalyst, to yield the desired polyethersiloxane which in turn is reacted with a polyisocyanate. The emulsions can be made (1) by dispersing the emulsifier in water and emulsifying the siloxane in this dispersion, or (2) by mixing the emulsifier with the siloxane to form a paste and adding water thereto with stirring. In a typical Example (1), a polyalkyleneglycolmonobutylether (obtained by copolymerizing ethylene and propylene oxides) was mixed with BF3 and tetrahydrofuran, and reacted with an epoxyorganooctasiloxane to yield a polyethersiloxane (containing -->COH groups in the polyether radicals) which was then reacted with toluylene diisocyanate at room temperature.  Water was added to this reaction product and a trimethyl-silyl-terminated dimethylpolysiloxane liquid was then dispersed therein to yield a stable emulsion which could be used for hydrophobing or as a mould-release agent.

Title: Method for emulsifying polymerizable compounds and effecting polymerization with the emulsions
IPC: C08F2/26
Filed: 1951-10-17
Abstract: Polymers of substantially water-insoluble monoethylenically unsaturated liquid compounds are made by mixing with agitation the monomeric material with 0.05 to 0.4 per cent, based on the weight of monomer, of an anionic emulsifier and water, the latter being present in an amount sufficient to form a 5 to 60 per cent aqueous solution and a water-in-monomer type of emulsion, discontinuing the agitation when the emulsion has formed, adding to the emulsion sufficient water containing 0.5 to 8 per cent based on the weight of monomer of another emulsifier, vigorously agitating the emulsion until the emulsion is inverted to a monomer-in-water type, and polymerizing the monomeric material. The polymerizable mixture may contain a plasticizer, e.g. dibutyl phthalate, and as catalyst a mixture of hydrogen peroxide and ferric nitrate.  The monomeric material may be vinyl chloride, vinylidene chloride, vinyl acetate, styrene, acrylonitrile, methyl vinyl or methyl isopropenyl ketone, esters of acrylic or methacrylic acid, or mixtures.  Anionic emulsifiers mentioned are petroleum hydrocarbon sodium sulphonate, decyl benzene sodium sulphonate, sodium lauryl sulphate, alkylaryl sulphonates, sodium lauryl sulphate, and the dihexyl ester of sodium sulphosuccinic acid.  The other emulsifying agent may be the sodium salt of the formaldehyde condensation product of naphthalene sulphonic acid, the sodium salt of an alkyl sulphonate or a sodium alkyl naphthalene sulphonate.

Title: Process for the polymerization of olefiin oxides with ferric compounds
IPC: C08G65/26
Filed: 1958-07-30
Abstract: Solid polymers of olefin oxides containing not more than 4 carbon atoms in the molecule are obtained by heating the oxide at 40 DEG  to 150 DEG C. with a catalyst having the empirical formula Fe(OH)x(OZ)3-x, where Z is an alkyl or halo-alkyl radical containing up to 6 carbon atoms or an aromatic radical containing 6 to 10 carbon atoms, and x is a positive number less than 3.  The preferred monomer is propylene oxide but ethylene oxide, epichlorhydrin and isobutylene oxide are also mentioned.  The propylene oxide may also be copolymerised with these other olefin oxides or with epoxybutanes or styrene oxide.  Specified catalysts are partially hydrolysed ferric methylate, ethylate, n- and iso-propylates, n-butylate, chloromethylate, chloropropylates, chlorobutylate, m-cresolate, xylenolate, and p-tert. butyl phenolate.  The degree of hydrolysis of the iron compounds is preferably from 40 to 90% corresponding to a value of x in the above formula of from 1,2 to 2,7, and the catalysts are probably polymeric.  The reaction is generally effected in bulk but non-aqueous diluents may be used such as hydrocarbons, ethers, ketones and ketals.  The polymer may be purified by dissolving in a solvent, e.g. hot acetone or dioxane, acidifying to convert the catalyst to a soluble salt, and crystallising the polymer from the solution at a low temperature, e.g. below -20 DEG C., or precipitating with excess water.ALSO:Iron compounds of the empirical formula Fe(OH)x(OZ)3-x, where Z is an alkyl or haloalkyl radical containing up to 6 carbon atoms or an aromatic radical containing 6 to 10 carbon atoms and x is a positive number less than 3, are prepared by incomplete hydrolysis of the corresponding alkylates and arylates; e.g. by adding the appropriate quantity of water to a solution thereof in a solvent such as alcohol at temperatures below 80 DEG C.  The compounds, which are used as catalysts in the polyermization of olefin oxides, appear to be polymeric.  The ferric alkylates and arylates may themselves be prepared by reacting ferric chloride or bromide with a metal alkylate or arylate or with an alkoxy or aryloxy magnesium chloride or bromide.  The ferric haloalkylates may be obtained by reacting a ferric alkylate with a haloacohol or by reacting ferric chloride or bromide with a haloalkyl magnesium halide or with an alkali metal haloalkylate.  The preparation is described of a composition presumed to comprise 59% of Fe(OH)2(OC2H5) and 41% [FeO(OH)]n.  Other compounds are listed.
