Title: Improvement in the vapour phase oxidation of titanium tetrahalide to produce rutile pigment
Inventor: EVANS ARTHUR WALLACE
IPC: C01G23/07
Filed: 1960-07-27
Abstract: Pigmentary TiO2 is prepared by the vapour phase oxidation of a titanium tetrahalide in a fluidized bed of inert particulate matter wherein a small amount of an aluminium halide (not a fluoride) is introduced into the bed separately from the titanium tetrahalide and a small amount of a silicon halide (not a fluoride) is introduced into the bed separately from the aluminium halide.  Preferably the aluminium halide is introduced in admixture with all or part of the oxygen-containing gas required for the reaction; in the latter case it is preferred that the oxygen-containing gas introduced with the aluminium halide is at least five times the amount required to oxidize the aluminium halide.  Any oxygen-containing gas not introduced with the aluminium halide is introduced either alone or with the titanium tetrahalide. In the illustrated embodiment the apparatus comprises a fused silica tube 1 containing a bed 5 surrounded by a furnace 8 and sealed at its base with a silica disc 2 through which pass inlets 3 and 4.  Aluminium trichloride and oxygen are supplied to inlet 3, the oxygen <PICT:0986660/C1/1> being supplied from pipe 9 and the aluminium trichloride being provided by passing chlorine from pipe 11 through heated reactor tube 12 containing aluminium turnings.  Titanium tetrachloride in admixture with silicon tetrachloride is introduced at inlet 4, the feed being introduced as a liquid to pipe 14 and vaporized in 15.  Alternatively the silicon tetrachloride can be introduced by pipe 18 either alone or with a carrier gas such as chlorine.  The bed 5, of dense TiO2 particles (-44 + 72 BSS), is initially fluidized with air until external heating by means of furnace 8 has raised it to 900 DEG -1200 DEG  C. The process may be carried out in the presence of a small proportion of moisture e.g. less than 2% by weight of the titanium tetrahalide. During the process 60 to 80% of the TiO2 formed is entrained, mainly in rutile form, in the affluent gases and carried away from the reaction chamber. The remainder of the TiO2 forms loosely bound accretions on the particles constituting the bed thus causing the bed to increase in volume.  The excess bed, or the whole bed, is removed and subjected to attrition, using wet or dry milling processes, to remove the loosely bound particles from the substrate and to separate them from one another, and the substrate material may then be returned to the bed.  The amount of aluminium and silicon halides introduced is preferably such that the weights of each of the alumina and silica in the final TiO2 pigment will be 0.1 to 7% and the relative proportions of the two halides introduced is normally such as to produce a weight ratio of alumina to silica in the final pigment of 20:1 to 1:5.  Specifications 900,050 and 919,019 are referred to.

Title: An improved process for the production of xanthine and alkyl- and aryl-xanthines
Filed: 1950-10-31
Abstract: Xanthines are prepared from 4-imino-5-isonitroso - 2 : 6 - diketo hexahydropyrimidines having hydrogen atoms and/or alkyl and/or aryl groups in the 1- and 3-positions by reducing the isonitroso compounds to the corresponding diamino compounds in the presence of one or more formic acid amides as reaction medium and heating the resulting reaction mixture at elevated temperature with formation of the imidazole ring.  Specified reducing agents are such sulphur-containing reducing agents as hydrogen sulphide and its salts, sulphurous acid and its salts, pyrosulphurous acid salts and hyposulphurous acid salts.  Suitable formic acid amides have the general formula HCO.NH.R, where R is hydrogen, alkyl or aryl. Preferably, the isonitroso compound is suspended in a 5-10 fold quantity of the amide.  Reduction is normally effected at about 100 DEG  C. and ring closure at about 170-180 DEG  C.  Examples describe the production of xanthine and theophylline, the amide being formamide containing a little formic acid and the reducing agent is sodium pyrosulphite.

Abstract: 1276809 Facsimile recording ROBERT BOSCH ELEKTRONIK GmbH 19 April 1971 [11 April 1970] 26840/71 Heading H4F  A grey value is produced by a facsimile recorder which is capable of recording only in black and white, by dividing a scanning voltage proportional to the instantaneous brightness value of the image to be reproduced into at least three ranges of magnitude by apparatus either at the transmitter or at the receiver, where the first range comprising the low magnitudes is converted to a first D.C. voltage, a second range comprising the high magnitude is converted to a second D.C. voltage, and at least one range between these two comprising the intermediate magnitudes is converted into a periodic pulse train. The first D.C. voltage does not cause the recorder to record, thus reproducing white, the second D.C. voltage causes the recorder to record a continuous trace to reproduce black, and the pulse train causes the receiver to record a broken trace to reproduce grey, as a trace is only produced for the duration of the pulse widths. The apparatus 4 producing this result comprises a number of threshold value switches 5-8, such as Schmitt triggers, which operate when the scanning voltage exceeds their threshold values and a number of pulse generators 9-11 controlled by these switches to produce pulse trains 9a-11a corresponding to grey values. These pulse trains are fed to a logic circuit 12 which also receives from threshold value switch 5 the continuous voltage representing black and which ensures that only that output voltage having the highest limiting value is transmitted.
