Title: Process and apparatus for the production of hydrochloric acid from waste gases containing hydrogen chloride
Inventor: KUNZER WERNER
IPC: C01B7/01
Filed: 1958-11-26
Abstract: Hydrochloric acid is recovered from gases <PICT:0849055/III/1> containing hydrogen chloride contaminated with impurities by absorption of the hydrogen chloride in water in a packed tower, the hydrogen chloride containing gases being heated to a temperature above the dew point of the impurities prior to the absorption step. Impure hydrogen chloride containing gases resulting from organic chlorination reactions and containing such impurities as benzene are passed through a conduit 4 and a heat exchanger 3 wherein they are heated to a temperature above the dew point of the impurities by indirect heat exchange with the hot aqueous hydrochloric acid formed by subsequent absorption of the gases.  The heated gases leaving heat exchanger 3 are conveyed by conduit 5 into the lower absorption zone where they first completely saturate the hot acid leaving heat exchanger 3 before passing into the upper absorption zone where the remaining hydrogen chloride gas is absorbed in water introduced by spray head 6.  Residual gases e.g. steam and impurities are discharged from the tower at 7.  Hot acid flowing down the tower enters cooler 9 through dip-seal 8 and is discharged by conduit 10. Heat exchanger 3 is provided with an outlet 11 for removal of collected solid or liquid entrainment remaining in the gases from the organic chlorination.  The heat of absorption of the hydrogen chloride is sufficient to maintain the required temperature in heat exchanger 3, but to enable initial starting of the process steam may be introduced through port 12 to provide sufficient heat to raise the temperature of the incoming gases above the dew point of the impurities until the heat of absorption becomes self-sufficient for this purpose.  Modifications of the process and apparatus include the positioning of the heat exchanger 3 between dip-seal 8 and cooler 9 or alternatively, the use of an external heat exchanger positioned in conduit 4 and heated by an external source e.g. steam, water, fuel oil or diphenyl.

Title: A process for the treatment of titanium dioxide
Inventor: RICHMOND JAMES THOMSON
IPC: C09C1/36
Filed: 1958-12-03
Abstract: Rutile titanium dioxide is prepared by calcining anatase in the presence of 0.1% to 5.0% by weight of boron phosphate (BPO4), until at least 90% of the anatase is converted to rutile.  Preferably the anatase has a particle size not exceeding 1 micron, and is calcined at 830 DEG C. to 1000 DEG C.  The calcination conditions may be so selected that the calcination does not exceed 5 hours, and is preferably 1-2 1/2 hours in duration. Other substances which promote the conversion of anatase to rutile may be added in addition to the boron phosphate, for example an oxide or oxides selected from the group zinc oxide, antimony oxide, magnesium oxide, and lithium oxide, or a seeding agent such as rutile titanium dioxide.  The anatase may be prepared by hydrolysing an aqueous solution of a titanium salt of a dibasic acid, for example titanium sulphate.  In an example, hydrous titanium dioxide was prepared by adding to a titanium sulphate solution, obtained by the sulphation of ilmenite, a nucleating liquor obtained by adding sodium hydroxide to titanium sulphate solution.  The mixed liquors were boiled, diluted with water, again boiled, and the precipitate of titanium dioxide was recovered, washed, and converted to rutile in accordance with the invention.

Abstract: 1288104 Detection of atmospheric turbulence COMPAGNIE GENERALE D'ELECTRICITE 17 Aug 1970 [22 Aug 1969] 39612/70 Heading G1A The atmosphere is scanned for turbulence by causing the lines of sight 15, 16 Fig.2 of at least one of two infrared detectors 9, 8 to undergo periodic angular movement such as represented by circles 5 and 6. A lens 10 is mounted in a casing 11 so that its optical centre is not on an axis of rotation 13. The casing is then rotated about axis 13 as indicated by arrow 12. The temperature of the atmosphere varies in accordance with the altitude and the detectors will produce a corresponding sinusoidal output signals. In the absence of atmospheric turbulence the outputs are identical to within a constant (see C and D) Fig. 4; but when there is turbulence in one line of sight, peaks 25, 26 such as on curves A and B are formed. These peaks can be detected by feeding both signals into a differential amplifier (23), Fig.4. The output of the differential amplifier would then be a signal such as E representing the presence of turbulence. In a further embodiment the portion of space scanned is further increased by imparting to both lines of sight of the detectors an azimuthal sweeping movement. In another embodiment, the angular movement is achieved by maintaining the lens fixed and moving the detectors 8 and 9.
