Title: Process for the production of higher boron alkyls and derivatives thereof from boronalkyls of lower molecular weight
IPC: C08F10/00
Filed: 1959-01-07
Abstract: Higher boron alkyls are obtained from lower boron alkyls by reacting a boron alkyl with ethylene in the presence of an aluminium trialkyl or aluminium dialkyl hydride, or aluminuium hydride.  The reaction is preferably effected at temperatures between 90 DEG  and 250 DEG  C. at superatmospheric pressures, for example, exceeding 20 atm.  The boron alkyls produced are not homogeneous compounds but statistical mixtures.  It is preferred to use 1 to 10% mol of aluminium trialkyl. The reaction products can be freed from catalyst by treatment with cold water, which may be acidified, with the exclusion of air.  The boron alkyls may be converted into dialkylborinic acid esters by oxidation, e.g. with gases containing only a small quantity of oxygen.  By stronger oxidation, e.g. with pure oxygen, they may be converted into monoalkylboronic acid esters.  The dialkylborinic acids and monoalkylboronic acids may be obtained together with the corresponding fatty alcohols by saponification of the esters with water or a substance with alkaline reaction.  Specification 812,787 is referred to.

Title: Improvements in and relating to methods of transforming glass batches into refined glass
IPC: C03B3/02
Filed: 1947-01-08
Abstract: 636,540. Glass manufacture. GALLOIS, R. Jan. 8, 1947, Nos. 672 and 673. Convention dates, June 1, 1946 and Oct. 23, 1946. [Class 56] In the manufacture of refined glass, raw batch is first converted into a product of uniform structure by pre-heating to at least 250‹ C. and then heating by a high frequency electric field to a temperature at which the endothermic reactions between the ingredients are complete ; this product is then melted and refined. As shown, batch material is carried by a screw conveyer C from a hopper A through a heat-insulated duct B (where its temperature is raised to 250‹ C. by a resistance E) to a distributer D supplying moulds G whose separable walls, e.g. of silica, fritted corundum or magnesium silicate, have a low coefficient of dielectric loss and whose two opposite sides carry electrodes connected to a source of highfrequency voltage whereby the batch material is uniformly and rapidly heated until the endothermic reactions are complete (e.g. at about 1000‹ C. for a soda-lime-silica batch). A heat - insulating support I, with the 'mould bottom, is then removed, the sides are separated and the block of aggregated material passes through a channel K to a glass furnace, preferably heated by passage of current through the glass, where it melts sufficiently rapidly on contact with the molten bath to allow convection alone to be relied upon for refining. A number of the above devices may successively feed a single furnace. The inner mould surfaces may be sprayed with a powdered mixture of alumina, Kieselguhr and graphite to prevent adhesion.

Title: A method of producing a glass object having a system of stresses therein
IPC: C03C3/089
Filed: 1961-01-09
Abstract: An object made of a glass which changes size continuously when submitted to increasing corpuscular radiation only up to a certain limiting dose of radiation, is treated with radiation of an intensity to produce such a dose of radiation at the surface. This produces a compression or tension near the surface with a corresponding tension or compression within the article according as the glass expands or contracts under irradiation.  The irradiation may be effected by electrons, protons, deuterons, tritons, alpha particles, nuclei of lithium or other elements, or neutrons. The particles may be accelerated or originate in nuclear reactions.  The glass may contain an element such as boron or lithium which undergoes, under neutron bombardment, nuclear transformation with the emission of energetic particles.  The natural boron may be enriched with boron 10, or the natural lithium with lithium 6.  Glasses which expand when irradiated may contain:- .SiO2.10-70% .Al2O3.0-20% .B2O3.0-50% .Li2O+Na2O+K2O.0-30% .MgO+CaO+SrO+BaO.0-30% .PbO.0-85%, such that SiO2+B2O3+Al2O3 < 85%, M2O+MO+PbO > 15%, and the content of B2O3, when present, is above 10% and of Li2O, when present, is above 10%, M2 and M representing alkali and alkaline earth metals respectively. An example of such a composition is:- .SiO2.47% .B2O3.20% .PbO.9.5% .Li2O.23.5%  Glasses which contract when irradiated may contain:- .SiO2.50-99% .Al2O3.0-20% .B2O3.0-50% .Li2O+Na2O+K2O.0-20% .MgO+CaO+SrO+BaO.0-30% .PbO.0-20% such that SiO2+B2O3+Al2O3 > 75% M2O + MO + PbO 0-25%, and the content of B2O3, when present, is above 1% and of Li2O, when present, is above 10%.

Title: Improvements in Clinometers and Direction Measuring Instruments.
Inventor: TAYLOR WILLIAM
IPC: G01C9/24
Filed: 1918-01-16
Abstract: 130,082. Taylor, W. Jan. 16, 1918. Levels and clinometers.-Clinometers &c. for measuring or indicating angular direction, of the kind in which a pivoted arm C carrying a level B or sighting-instrument is pressed by a spring E against the end of a rotating nut G which serves to measure the angle recorded, are constructed so that the parts most affected by wear are readily interchangeable and can be adjustably set in any instrument, so that special calibration of each instrument is unnecessary. With this object, the invention consists in forming the cam J so that equal angular movements of the arm C will be effected by equal rotational movements of the nut G, and in making the cam axially adjustable along the arm C so that the point of contact with the nut can be varied. The use of this special cam enables the known form of scale inscribed on a helix on the rotating nut to be replaced by a fixed straight-line equally-divided scale K for the degrees, and a circular equally-divided scale g for the lesser graduations. The axial adjustment of the cam is effected by a screwed rod c<3> having lock-nuts c<4>, c<5> engaging the opposite sides of a lug. Clamping-screws c, c<1> secure the cam in the adjusted position. The instrument may be used in various ways; for example, the base may be placed upon an inclined surface and the angle of inclination measured by adjusting the arm to an horizontal position by means of the level, or, for direct measurement of the angular distance between two points, a sighting-instrument may be mounted on and parallel to the base, and a second sight on the arm in place of the level. This form of instrument with two sights can be arranged to measure angles in azimuth by arranging the nut horizontally instead of vertically.
