Patent SE-318235-B (SE)
Inventor: HUKKI R
IPC: B03D1/26
Filed: 1966-06-14
Abstract: 1,058,914. Froth flotation. OUTOKUMPU OY. June 14, 1965, No. 25097/65. Heading B2H. Froth flotation apparatus operating under a common head of vacuum comprises a pre-conditioning and aerating unit 1, into which pulp and gas are introduced via pipes 3, 4, the pulp being fed via a pipe 6 into a flotation chamber 8. Additional gas is introduced via a pipe 13. Froth is collected by a section 10 and directed into a bubble column 19. Preconditioned particles, treated with reagents to be floatable proceed upwards, and unwanted particles downwards, the downward movement being assisted by wash solutions introduced at 21. Final concentrate is drawn into a cyclone 23 for separation of solids and liquids, and concentrate pulp is discharged into a vessel 25 and over a weir 16, vessel 17 and weir 18. Gas separated in the cyclone is directed via a conduit 27 to a vacuum pump. In a further embodiment, five flotation chambers are employed operating under a common head of vacuum. Pulp material is drawn into rough flotation units (28, 29 Fig. 2) and the rough concentrates rise in columns (37, 38) and are combined in a chamber (30), separation of gas being effected in cyclones (41, 42.) Tailing pulp from the chamber (30) is returned to the chamber (28). Further flotation scavenger chambers (31, 32) receive the rougher tailings for further separation and the coarsest tailings are discharged at (53, 54).

Title: Catalyst and method for producing the catalyst
Inventor: KRISTIANSEN L
IPC: B01J23/80
Filed: 1981-03-27
Abstract: This invention relates to a catalyst and a method for producing said catalyst. At least 60 percent by weight of the catalyst consists of copper oxide, aluminum oxide-spinel and 60-100 percent of the copper present is bound to aluminum oxide as copper oxide, aluminum oxide-spinel, where the molar ratio Cu:Al=0.25-0.50. The catalyst itself contains 1-20 percent by weight of zinc oxide which is present in the pores of the spinel. Further amounts of zinc oxide may be admixed mechanically or be present as a coating on the catalyst tablets. The catalyst is especially well suited for conversion of carbon monoxide with steam to hydrogen. The catalyst is produced by precipitation of copper- and aluminum salts at pH=6.0-6.5 during addition of an ammonium carbonate solution. After filtration and drying, the product is calcined at 750 DEG -850 DEG  C. until there is obtained a product having a 60-100 percent spinel structure. Zinc salt is introduced in the pores of the spinel, and the product thereby formed is heated up to at least the decomposition temperature for the zinc salt which is then converted to zinc oxide. Possible addition of zinc oxide in addition to that introduced into the pores of the spinel may be admixed mechanically.

IPC: A23D7/015
Filed: 1989-02-16
Abstract: The present invention is concerned with an edible fat-containing product comprising two distinct fat phases (A) and (B); fat phase (A) comprising indigestible polyol fatty acid polyesters and fat phase (B) essentially consisting of digestible fat, wherein fat phase (B) contains an oil-soluble vitamin at a concentration level that is at least twice as high as the concentration level of said vitamin in fat phase (A) and in which fat phase (A) and fat phase (B) are separated from each other by a third phase which is essentially impervious to the oil-soluble vitamin. We have found that the products according to the invention offer the advantage that the negative influence of indigestible polyol fatty acid polyester on the adsorption of an oil-soluble vitamin is overcome in a very effective manner Another aspect of the present invention relates to a process for the preparation of an edible fat-containing product, comprising combining a first fat containing fraction of which the fat essentially consists of digestible fat and which first fraction contains an oil-soluble vitamin, with a second fraction containing indigestible polyol fatty acid polyesters, wherein the concentration level of the oil-soluble vitamin in the digestible fat of the first fraction is at least twice as high as in the polyol fatty acid polyesters of the second fraction, and subjecting the combined fractions to such mild processing conditions that the final product comprises the fat of the first and the fat of the second fraction in the form of two distinct fat phases.

Title: Apparatus for the recovery of heterogeneous waste, particularly heterogeneous waste plastics material.
Inventor: FORMASERO RENATO
IPC: B29B17/00
Filed: 1992-09-10
Abstract: Apparatus for the recovery of heterogeneous waste plastic material, of two or more plastics, utilises a cold mixer-homogeniser which feeds a hot mixer-homogeniser. The cold homogeniser is fed with material from a bladed chopper through a hopper. A screw conveyor has a screw with three sections, a loading section, an intermediate section and an output section. The loading section receives the material from the hopper and advances it to the intermediate section where the screw has several off-cuts of a helical thread, each of which has a predetermined angular arrangement, with successive threads having winding senses opposed in an alternating sequence. Such an arrangement encourages intense mixing of the material. The output section has a continuous screw thread whose sense of winding is the same as that of the loading section, again advancing the material towards the outlet where it is conveyed to an intermediate screw conveyor feeding the hot plasticising and homogenising unit.
