Abstract: A method for production of toxin-binding, non-toxic, modified, biopolymers and the use thereof for the treatment of septic shock, infections and toxic states and to the use of them as carriers for transportation of biologically or therapeutically important materials (enzymes or drugs) into phagocytes or cells bearing Fc and complement receptors and as a natural source of energy for cells. The toxin binding, non-toxic structurally modified biopolymers are prepared by the reaction of polysaccharides containing alpha 1,4 or 1,6 linkages with glucose-1-phosphate catalyzed by glycogen phosphorylase enzyme in a buffer solution at pH 6.8-7.4 at a temperature of 20.degree.-30.degree. C. and by the separation of the obtained biopolymers in a well-known manner.

Abstract: The invention relates to a process for the integral optical examination of damaging mechanical stresses arising in the bottom-part of bottles and hollow glasswares. In accordance with the process the bottom-part of the glasses/bottles/is illuminated with a light bundle from the mouth, the cross-sectional intensity distribution is controlled by the aid of a light bundle with predetermined angle of aperture, with the integral optical system the bottom is illuminated with a light with quasi-homogeneous intensity. The passing light is modulated and led into the photodetector, the signal of which is analysed through a band-filter. The invention includes the apparatus for the implement of the process according to the invention. The apparatus has a laser (1), a laser bundle (2) emitted therefrom, a polar filter (3), connected with a light-chopper (4), a bundle stretcher consisting of the collecting lenses (5,6), the diaphragm (8), a polar filter (14) and the photodetector (15).

Abstract: An improved process for accelerating the digestion process in the Bayer alumina process is provided which promotes both the goethite-hematite conversion and a more perfect and quick dissolution of the diaspore. The above is achieved by carrying out the digestion in the process of 5-20% by weight calculated on the dry weight of the bauxite of a novel hydrogarnet catalyst.

Abstract: An automated wet sieving apparatus and process are provided comprising a wetting liquid distributor which is coupled by eccentric disks to a motor which drives the distributor in an orbital path for supplying the liquid onto a sieve. Means are provided for creating alternating vacuum and pressure below the sieve. The vacuum draws undersized particles whose size is being determined through the sieve and the pressure loosens blinding particles from the sieve. Preferably, the sieve is cyclically tilted as the wetting liquid is being distributed onto the sieve.

Abstract: A method of electrolytically recovering gallium and/or alkali metals from alkali metal solutions, preferably aluminate (sodium aluminate) liquors from aluminate production in which the gallium or alkali metal is electrolytically deposited on a mercury layer of the thickness of several microns applied to a metallic support which is more electronegative than mercury (preferably copper) by amalgamation or cementation from a mercury salt solution. The deposition of metals is carried out at a temperature below 50.degree. C and the cathode is then treated with a solvent, e.g. mercury or water, to remove the deposited elements.
