Title: Process for the production of a crystalline sodium perborate trihydrate
IPC: C01B15/12
Filed: 1956-09-26
Abstract: A sodium perborate trihydrate of formula Na[BO2.H2O2].2H2O is crystallized at 12-86 DEG  C. from an aqueous solution of sodium perborate or components forming sodium perborate, in the presence of a sodium salt of hydrochloric, sulphuric or nitric acid.  The crystallization may be performed in the presence of seeds, e.g. of the solid trihydrate or of sodium percarbonate; in the presence of solid sodium perborate tetrahydrate (Na[BO2.H2O2].3H2O) (which continuously dissolves and reprecipitates as trihydrate); or in the presence of stabilizers such as magnesium silicate, stannic oxide and tetrasodium ethylenediamine tetraacetic acid.  Suitable components for the production of sodium perborate in solution are sodium metaborate and hydrogen peroxide or sodium peroxide, hydrogen chloride and borax.  If desired, after removal of the trihydrate crystals, the mother liquor may be suitably supplemented and reused for the precipitation of a further batch of the crystalline product.

Title: Production of open chain oligomers of 1,3-dienes
Inventor: SEIBT HUBERTUS
IPC: B01J31/16
Filed: 1963-07-26
Abstract: Open chain dimers of 1,3-diolefins are obtained by dimerizing the diene in the presence of a catalyst containing zero valent nickel and a compound of trivalent phosphorus, arsenic or antimony and in the presence of at least an equimolar amount with reference to nickel of a non-aromatic organic hydroxyl compound, i.e. one wherein the hydroxyl is attached to an aliphatic or cycloaliphatic carbon atom. The catalysts are conventional and may also contain carbon monoxide, an olefin, an acetylene or an a ,b -olefinically unsaturated aldehyde or nitrile and may be formed in situ from a nickel compound, reducing agent and electron donor. Amounts of 0.001-1% by weight calculated as nickel based on diene are used.  The hydroxyl compound may contain 1-15 carbons and is preferably saturated and may also contain alkoxy groups, e.g. methanol, ethanol, propanols, butanols, 2-ethylhexanol-1,crotyl alcohol,cyclohexyl carbinol, cyclohexanol, cyclo-octanol, benzyl alcohol, b -phenylethyl alcohol, lauryl alcohol, cinnamyl alcohol or methyl or butyl glycol.  The alcohol is preferably used as solvent also being used in molar amounts of 2-5 times nickel; alternatively a hydrocarbon solvent is added.  A phenolic or amine polymerization inhibitor may be added.  Reaction is effected at 0-250 DEG C. and up to 20 atmospheres gauge.  Catalysts containing phosphites yield from butadiene mainly octatriene-1,3,6, those containing phosphines octatriene-1,3,7, and those containing phosphorous acid triamides octatriene-2,4,6.ALSO:3 - (But - 2 - enyl) - 4,5 - diacid anhydridecyclohexene-1 is obtained by a Diels-Alder condensation of octatriene-1,3,6 with maleic anhydride.

Title: Improvements in and apparatus for the manufacture and production of gases rich in nitrogen and free from oxides of nitrogen
IPC: C01B3/02
Filed: 1935-10-29
Abstract: Mixtures of nitrogen with small amounts of hydrogen or oxygen, or pure nitrogen are <PICT:0463804/III/1> obtained by first producing a mixture of nitrogen and hydrogen rich in hydrogen by the process described in the parent Specification by the catalytic combustion of ammonia with less than 0,75 part by volume of oxygen and subsequently partly or wholly burning the hydrogen present by means of oxygen or air. Oxides of nitrogen or nitrogen-oxygen mixtures poor in oxygen may also be used for the second combustion, thus increasing the nitrogen content of the resulting gases.  According to examples: (1) 16 cubic m. of ammonia and 32 cubic m. of air are passed through the catalyst c consisting of nickel nets in the apparatus shown.  18 Cubic m. of air are fed in through pipe h into the space behind the nets where the heat from the catalyst is sufficient to initiate the second combustion.  The reaction gases pass over water d to absorb unconverted ammonia, pipes b and e being cooled by water jackets g. 50,8 Cubic m. of a gas mixture containing 6,2 per cent hydrogen and 93,8 per cent nitrogen are obtained; (2) by the partial combustion of 14,75 cubic m. of ammonia and 29,5 cubic m. of air and subsequent addition of 26,7 cubic m. of air in the same apparatus, a gas mixture containing 99 per cent nitrogen and 1 per cent oxygen is obtained.

Title: A method of operating vacuum tubes
IPC: H01J65/04
Filed: 1920-10-25
Abstract: 153,002. Schaeffer, E. Aug. 26, 1919, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes.-In a tube for use with alternating or pulsating current, at least one of the electrodes is outside the casing and is connected to the outer wall by a conducting liquid which offers little resistance to the rays produced; the current is communicated to the inside by condenser action. The lamp shown comprises an inner chamber containing an aluminium or other electrode i, connected to the cap t, and is surrounded by an outer vessel g filled with conducting liquid to which current passes by an electrode k connected to a contact m. The electrode k may enter the liquid at the top of the annular space instead of as shown. The lamp contains a highly rarefied gas, preferably one of the rare gases of the atmosphere. In a modification, the inner vessel is cylindrical and is completely enclosed by an outer cylindrical vessel having terminal caps at the ends, one of which is connected to the inner electrode and the other to the liquid. The vessels may be of glass or quartz and may be united by fusion or cementation or by screwing. The injurious effects of electrolysis of the liquid when pulsating direct current is used may be obviated in one of the following ways; (1) by allowing escape of gas and replacement of liquid either automatically from a reservoir or through a stopper by hand; (2) by making the outer vessel of such size that the effects are negligible; (3) by using as the conducting liquid a solution of one or more hygroscopic salts, e.g. chlorides, bisulphates, or carbonates, which absorb lost water from the atmosphere; (4) by using a depolarizer which may be oxidizing or reducing according to the direction of the current, the immersed electrode optionally being of a metal such as zinc or copper which dissolves when current passes, nitric acid, perchlorates or chlorates may be used as depolarizers; (5) by using a liquid containing an intermediate-stage oxidation product of a chemical compound, e.g. a chlorate or a hypochlorite, the oxidation and reduction products formed by electrolysis re-combining on diffusion; (6) by recombining the products by a catalytic agent 'such as spongy platinum. When several tubes are worked in parallel they may be enclosed in the same liquid container or may have separate containers connected by passages, only one immersed electrode being used. When the tubes are worked in series, the liquid may form some of the electric connexions, no external connexion to the liquid being necessary in this case. The invention is applicable to tubes for producing cathode rays, R÷ntgen rays, or canal rays, and to valves for use in wireless telegraphy.
