Abstract: Polymeric alkoxides, phenoxides or acyloxides of, titanium, zirconium or tin having one alkoxy, phenoxy or acyloxy group per atom of tetravalent element are prepared by reacting 1 mol of a tetra-alcoholate or tetrahalide of the element with 1.5 mols of water in the presence of an alcohol or phenol or of 1 mol of a monobasic organic acid, and heating to above 100 DEG C. until liberation of hydrogen halide or alcohol is complete, a hydrogen halide binder being present when the starting material is a halide.  The products are mainly tetramers or octamers. An inert solvent may be present. When alkoxides and phenoxides are obtained they may be reacted with monobasic organic acids to obtain the acyloxy compounds. In examples zirconium isopropoxide, zirconium n-butoxide, tin tetrabutoxide, titanium butoxide, titanium isopropoxide and titanium tetrachloride, are reacted with water in the presence of stearic acid, isopropyl alcohol, acetic acid, dodecyl benzene, sulphonic acid and nonyl phenol, the solvents being xylene, hexane, toluene and a mineral oil; triethylamine is used as a hydrogen halide binder.  Other starting materials are mentioned.ALSO:Polymeric alkoxides, phenoxides or acyloxides of silicon, titanium, zirconium or tin having one alkoxy, phenoxy or acyloxy group per atom of tetravalent element are prepared by reacting 1 mol of a tetra-alcoholate or tetrahalide of the element with 1.5 mols of water in the presence of an alcohol or phenol or of 1 mol of a monobasic organic acid, and heating to above 100 DEG C. until liberation of hydrogen halide or alcohol is complete, a hydrogen halide binder being present when the starting material is a halide.

Title: Methods of making cubic boron nitride
Inventor: JR ROBERT HENRY WENTORF
IPC: C04B35/583
Filed: 1958-01-27
Abstract: <PICT:0860499/III/1> <PICT:0860499/III/2> Cubic boron nitride is produced by subjecting hexagonal boron nitride to an elevated temperature and pressure in the presence of a catalyst comprising an alkali metal, alkaline earth metal, lead, antimony, tin or a nitride of one of the foregoing metals. Three parts of hexagonal boron nitride are mixed with one part (by volume) of the catalyst and the mixture is pressed and heated in a carbon or tantalum tube 33 between dies 22 of an hydraulic press, with electric current flowing through conductive parts 22, 38, 32 and the tube 33.  With magnesium as the catalyst the conversion is effected with temperatures of 1300 DEG  to 2100 DEG  C. and pressures of 69,000 to 95,000 atmospheres applied for three minutes.  The conversion is also described as being effected with sodium, potassium, lithium, barium, calcium, lead, antimony, tin, magnesium nitride, lithium nitride, magnesium nitride and tin, magnesium nitride and magnesium and with magnesium nitride and sodium at similar pressures and temperatures, higher pressures being necessary for higher temperatures.  Larger crystals of cubic boron nitride, including octahedral fragments 300 microns on edge, are obtained from the mixture comprising boron nitride, magnesium nitride and sodium than from other mixtures.  In a further example a magnesium wire in boron nitride is used.  The cubic boron nitride is very hard and may be used to tip cutting tools, Fig. 5, to which it is secured with silver/copper solder and titanium hydride, or to form the abrasive portion of p  grinding-wheels or even to grind diamonds. Specifications 829,990 and 830,210 are referred to.
Patent GB-489576-A (GB)
Title: Improvements relating to the production of glycols
IPC: C07D301/26
Filed: 1937-01-29
Abstract: Chlorhydrin solutions of relatively high concentration, up to 15-20 per cent, are produced continuously by reacting gaseous chlorine, a mixture of olefines and water together simultaneously, the chlorine, olefines and one or more inert gas diluents being passed into a flowing stream of cold water.  Suitable diluents are saturated hydrocarbons, and these may be obtained mixed with the olefines by the vapour phase cracking process of the petroleum industry.  The olefine content of the gases may be as low as 10 per cent.  In an example, " gipo " gas of specified composition is passed through porous thimbles of alundum or sintered glass into a tower into which water at 5-20 DEG  C. is continuously fed at the top, the reaction products being withdrawn at the bottom. Chlorine is fed into the tower through porous thimbles at a short distance above the hydrocarbon gas inlet.  The saturated hydrocarbons pass out at the top of the tower.  The feed of the hydrocarbon gases is regulated so that ethylene, which reacts more slowly than propylene and butylene, is completely reacted. The tower may be replaced by one or more shorter columns provided with stirring means.  The aqueous solution produced is steam distilled.  Olefine chlorides are first removed, and then an azeotropic mixture of chlorhydrins and water boiling at about 96 DEG  C.  When the concentration of the chlorhydrin solution obtained from the tower is as high as 15 per cent, the distillation operation may be omitted.  The chlorhydrin solution is run into hot milk of lime at above 80 DEG  C. or a suspension of the oxides, hydroxides or carbonates of the alkaline earths or of magnesium, and the resulting olefine oxides are passed into a 0,5 per cent solution of sulphuric or other mineral acid below 50 DEG  C., preferably at 20 DEG  C.  The glycols produced are separated from the acid by precipitating it with lime, marble, limestone or other suitable compound.  The solution is filtered, evaporated and if desired, distilled.  The glycol mixture is suitable as an antifreeze mixture in motor cars.

Abstract: 549,440. Automatic exchange systems. WESTERN ELECTRIC CO., Inc. March 16, 1942, No. 3424. Convention date, Feb. 8, 1941. [Class 40 (iv)] In a non-numerical switching system, e.g. a primary cross-bar switch, each outlet has a discharge tube 113, 114 &c. and all the tubes belonging to idle lines tend to break down when , a demand for an outlet is made by the operation of a line relay such as 106 and in consequence, potential is applied by a group relay 126 to the main electrodes of the tubes. As soon as one discharge begins, however, the negative potential applied to the cathodes is reduced, owing to the presence of a common inductance 127 in the common cathode side of the discharge path and at the same time the reduction in the positive potential at the anode of the discharged tube due to the presence of a select magnet such as 111 in its individual discharge circuit causes a corresponding momentary reduction in the anode potentials of the other tubes owing to the connection of the anodes via individual condensers 132, 133 &c. to a common lead. The discharge of any other tube thus prevented &c. when the desired discharge is fully established, the potential drop due to the resistance of the common inductance is enough to maintain the inhibition. The operated select magnet energizes the appropriate hold magnet 108, 109, 137 &c. which releases the line relay to restore the tubes to normal and remains held by the usual ground on the third wire. The connection of this wire to the control electrode of the discharge tube prevents the operation of the latter while the outlet is busy. The tubes are preferably argon-filled.
