Title: Serial coding and decoding for switching signals - using quantising raster of stepped level value for coding and coincidence evaluation for decoding
Inventor: KOLLER ROMAN
IPC: H03M9/00
Filed: 1980-05-28
Abstract: The coding of the switching signals in a signal train takes place by generating a level value for each switching signal according to the number of the signals to be coded. The number is provided by a preset quantising raster. A time function value, such as a pulse duration is also used, or a rising value, or a frequency. The decoding from the signal train takes place by coincidence evaluation of a differently programmed response threshold for each coded signal. The decoding also takes into consideration the level and the time function value. The excess of a programmed level threshold value, with simultaneous excess of a programmed time function threshold value corresponds to a switching signal, associated to these threshold values by decoding. Quantising rasters of the level values and the time values are used as coding and decoding instructions.

Title: Removal of iron, titanium and silicon values - from aluminium-contg. materials, by chlorination using aluminium chloride and beneficiation
Inventor: WESTON DAVID
IPC: C01F7/58
Filed: 1980-09-08
Abstract: One, two or three chlorination steps are used using aluminium chloride as the main or only chlorinating agent in the first step and chlorine or phosgene in the subsequent steps. The material is first treated, if necessary, to reduce the iron content to max. 8.0 wt. % (calc. as Fe2O3), e.g. by mangetic treatment, and may then be granulated or pelletised. After dehydration by heating at 625-1050 deg.C, the material is chlorinated at 550-1050 deg.C using AlCl3, including recycle impure AlCl3, and opt. also phosgene or chlorine plus a reducing agent as chlorinating agent in a 25% stoichiometric excess of the amount needed to convert all the iron materials to their chlorides. The gaseous effluent is condensed or fractionated to recover chlorides of iron, etc. and the residue, contg. AlCl3, is recycled. The chlorinated material may then be further chlorinated to remove Si and/or Ti values and gives alumina or aluminium chloride, free from Fe, Si and Ti, as the product. The methods produce cell grade alumina or AlCl3 from bauxite, bauxitic clays or other clays without the need for any complex separation processes.

Title: "Method for improved utilisation of chemisorbents in gas purification plants"
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/00
Filed: 1981-06-11
Abstract: The invention relates to repeated use of chemisorbents for gas purification, particularly those reacting on the surface, such as, e.g. hydrated lime. It is known to recycle these chemisorbents after first-time use, into the chemisorption section where they are again able to absorb pollutants, but only in small amounts. The utilisation of the chemisorbents is improved by these being reprocessed, prior to recycling, in a steam-jet mill and being fed once more to the chemisorption appliance. Reprocessing in the steam-jet mill results not only in new surfaces being formed, owing to comminution of the particles, but these are, moreover, activated by moistening.

Title: Process for purifying hot waste air containing hydrofluoric acid or hydrofluoric acid and sulphur oxides, and clay- and/or glazing-containing effluent from the ceramic industry
Inventor: SCHIPPERT EGBERT DIPL CHEM DR
IPC: B01D53/50
Filed: 1981-11-19
Abstract: In this process, on the one hand the waste air is purified by means of washing water and the hydrofluoric acid present in the effluent is then removed by precipitation of calcium fluoride. On the other hand, the clay- and/or glazing-containing effluent is neutralised and clarified in a settling tank. In order to reduce the water consumption and the investment costs, the washing water containing hydrofluoric acid is held at a pH of less than 3.5 by metered addition of water with simultaneous discharge of effluent containing hydrofluoric acid. The effluent containing hydrofluoric acid and the clay- and/or glazing-containing effluent are then combined in a tank and the clay- and/or glazing-containing effluent is cleaved by the effluent containing hydrofluoric acid, and both effluents are together neutratilised with milk of lime. The calcium fluoride and calcium sulphate formed in the neutralised effluents and the clay and/or glazing solids are separated off by sedimentation in a common settling tank. At least a part of the clarified water leaving the settling tank is added to the washing water containing hydrofluoric acid for dilution. <IMAGE>
