Title: Method of producing zirconium oxide from zirconium tetrachloride
Inventor: BRUGGER WILHELM
IPC: C01G25/02
Filed: 1957-09-17
Abstract: Zirconium oxide of high purity is prepared by reacting solid zirconium tetrachloride with superheated steam or aliphatic alcohols in vapour form at temperatures between 120 and 310 DEG  C. The alcohols preferably contain between one and five carbon atoms and the reaction products contain the corresponding alkyl halides.  If alcohols are employed it is preferred to complete the reaction by means of superheated steam.  The zirconium oxide formed may be calcined at 1000 DEG  C. to produce zirconium dioxide of 99.9 per cent purity.  According to examples: (1) a pure solid zirconium tetrahalide was treated with superheated steam at 220 DEG  C. to produce zirconium oxide containing water and hydrogen chloride, which was then calcined for two hours at 1000 DEG  C. to produce pure zirconium oxide (2) Solid zirconum tetrachloride was reacted with steam at 220 DEG  to 240 DEG  C. and the temperature was then raised to 500 DEG  to 550 DEG  C. whilst admitting further steam; the product was calcined at 1000 DEG  C. (3) Solid zirconium tetrachloride was treated with methanol vapour at 280 DEG  C. and the resulting methyl chloride was purified from traces of dimethyl ether and unreacted methanol and moisture by means of caustic soda and hydrochloric acid and was then liquified.  When 80 per cent of the tetrachloride had reacted, superheated steam was passed through to complete the reaction and the oxide obtained was calcined at 1000 DEG C.ALSO:Alkyl halides are produced by reacting aliphatic alcohol vapours at 120-310 DEG  C. with solid zirconium tetrachloride. C1 to C5 alcohols are preferred.  According to an example (3) solid zirconium tetrachloride is treated with methanol vapour at 280 DEG C.  The methyl chloride is treated with NaOH and HCl to remove traces of dimethyl ether, methanol and moisture and thereafter liquefied.

Title: Process for the manufacture of derivatives of dinaphthylene dioxide
IPC: C07D493/06
Filed: 1928-10-11
Abstract: 323,806. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Oct. 11, 1928. Samples furnished. Dinaphthylene dioxide derivatives of the general formula :- in which x represents hydrogen or a substituent, are prepared by heating a derivative of #-naphthol having free 1- and 8- positions, or of #-dinaphthal having free 8- and 8<1>-positions with a metallic oxide such as copper oxide or pyrolusite, in a high boiling organic solvent such as nitrobenzene or trichlorbenzene. In exampLes (1) di-o-toluidide of dinaphthylene dioxide-3.3<1>-dicarboxylic acid is obtained by heating the o-toluidide of 2.3-oxynaphthoic acid with pyrolusite in nitrobenzene. Similarly the corresponding dianilide, di-m-nitranilide, di-p-anisidide, di-alpha-naphthalide and di-#-naphthalide are obtained; also the diethyl ester of this acid, from which the free acid may be prepared by alcoholic saponification. (2) the ethyl ester of 2.6-oxynaphthoic acid (obtained by saturating the acid dissolved in ethyl alcohol with hydrochloric acid and distillation in vacuo) is heated with copper oxide in nitrobenzene to give a dinaphthylene dioxide derivative. (3) The anhydride of the 4.5: 4<1>.5<1>-tetracarboxylic acid of dinaphthylene dioxide is prepared by heating 3-oxynaphthalie acid anhydride with copper oxide in nitrobenzene, and the acid itself by treating the anhydride with hot alkali solution. (4) 6.6<1>- dimethoxydinaphthylene dioxide is similarly obtained from 6-methoxy-2-naphthol, and yields the corresponding dihydroxy derivative on treat ment with aluminium chloride. (5) 7.7'-dibenzoyldiaminodinaphthylene dioxide is similarly obtained from 7-benzoylamino-2-naphthol. These products are of use as dyestuffs or as intermediates therefor.

Title: Method of producing metal-film resistors
IPC: H01C17/08
Filed: 1963-07-26
Abstract: 1,045,186. Resistors. STANDARD TELEPHONES & CABLES Ltd. July 26, 1963 [Aug. 1, 1962], No. 29709/63. Heading H1S. In the production of metal-film resistors by the deposition of the metal, e.g. by evaporation or sputtering, on to a surface of a carrier of an insulating material, the carrier being so placed with respect to the source of the metal that a metal film is formed only on the portion of the carrier's surface which faces the source, the configuration of the carrier being such that the portion of the surface on which deposition occurs masks the remainder of the carrier's surface from the source, the metal film is produced having a resistance which is less than a required value and this is then partially oxidized so that its resistance is substantially equal to the required value. In one embodiment, the carrier, e.g. a number of glass rods or threads, is placed on the anode of a sputtering field facing the cathode which consists of the metal, e.g. tantalum, to be used. When a potential is applied between the anode and cathode, metal is deposited only on the upper surface of the glass rods or threads. The metal film formed on each rod or thread has a maximum thickness on the uppermost part, tapering at the sides, and this has the advantage that the resistance is due mainly to the relatively thick portion. Thick layers have the advantages of small voltage coefficient, stability, high resistance to heating and the capability of dissipating a high power. The resistance of the film is increased to the required value by electrolytic oxidation, as a result of which the film is entirely covered by a protective oxide layer. Additional surface protection can be obtained if necessary by encapsulating the resistor.
