Patent NO-172063-B (NO)
Inventor: DIDERICHSEN BOERGE KRAG
IPC: C12R1/07
Filed: 1985-12-11
Abstract: A novel method for stabilization of extra-chromosomal elements in bacteria during cultivation without use of antibiotics in the medium has been developed. The method comprises transformation of a host bacterium having a defect in a chromosomal gene needed for the synthesis or maintenance of the cell envelope with an extra-chromosomal element capable of suppressing the requirement caused by the chromosomal gene defect of the host bacterium. The invention furthermore provides for such transformed bacteria and stabilized extra-chromosomal elements and for a method for producing desirable products by inserting a gene for the desirable product into a stabilized extra-chromosomal element and cultivation of suitable host bacteria containing the stabilized extra-chromosomal element comprising the gene for the desirable product. It was demonstrated that according to the principles of this method, a plasmid including the dal gene of Bacillus subtilis and a gene encoding a desirable product can be maintained in an appropriate dal<->B. subtilis host in conventional media. The method thus allows for improved product yield and quality.

Title: Process for milling raw homogene and/or heterogene mineral material in system of autogenous primary milling
Inventor: BORELL CARL MICHAEL
IPC: B02C21/00
Filed: 1982-11-25
Abstract: The present invention relates to a method for comminuting a coarse lump mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction is determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a size distribution graph obtained by screen analysis of a grinding mill charge of material obtained after an autogenous grinding process. The smallest particle size of the coarse fraction is greater than the particle sizes in the upper of said inflexion points, and the ratio between said fractions is determined on the basis of achieving a given charge quantity for a particular, selected set-point power value fo the mill in question, and determined with respect to a selected degree of grinding.The grinding efficiency of autogenous primary grinding mills is greatly improved by means of the invention (Figure 4).

Title: Washing column
Inventor: MALEN BERNARDUS GODEFRIDUS MAR
IPC: B01D9/04
Filed: 1982-12-15
Abstract: A washing column for the continuous separation between a solid chemical formed in a liquid multi-component system, on the one hand, and the mother liquor in which the solid chemical is suspended, on the other. In a cylindrical working space a stationary, straight, plane washing front is maintained in a packed bed of the solid chemical substance between the mother liquor, on the one hand, and a melt of the solid chemical, on the other. According to the invention, the washing column is double-walled to form an enveloping space, which contains a heat insulating medium and can be pressurized to conform to the pressure within the column. This construction permits the use of a relatively thin, glass inner wall of uniform wall thickness and inner surface. This renders the column resistant to corrosive chemicals, reduces the effect of heat exchange with the surroundings, and prevents instabilities in the washing front.

Title: Process for purifying metals by segregation
Inventor: WINTENGERGER MICHEL-GEORGES
IPC: C22B19/32
Filed: 1983-03-30
Abstract: The present invention relates to a process for purifying metals, such as aluminum, by segregation, wherein, by controlled cooling in the upper part of a volume of liquid metal to be purified, which is contained in a crucible and disposed in a furnace, small crystals are caused to form, the crystals falling towards the bottom of the container under the force of gravity. The small crystals are compacted so as to cause the formation of a compact layer of large purified crystals. This process is distinguished from the known processes in that, to enhance the purification effect, the thermal flux is so adjusted as to completely and progressively re-melt the lower part of the mass of large crystals which are formed, with the re-melting action being propagated upwardly so as permanently to maintain a layer of large crystals which separates the re-melted liquid entirely disposed in the lower part from the remaining mother liquor. That process makes it possible to attain extremely high levels of purification, in relation to very high fractions of the initial mass of aluminum which is to be purified. The process can be applied to metals such as aluminum, lead, zinc, magnesium and silicon containing eutectic impurities in hypoeutectic amounts.
