摘要： The copper powder contains at least one substance, which is not soluble in copper, e.g. Al.sub.2 O.sub.3, TiO.sub.2, SiO.sub.2 or B.sub.2 O.sub.3. For the production of this copper powder, a surplus of copper metal granulate is mixed with an ammonium salt and/or ammonium hydroxide, together with a saline solution in an aqueous solution, while a gas containing oxygen is added, and at a pH-value of at least 4. A copper-containing precipitate is produced, which is separated and treated at a temperature in the range from 150.degree. to 500.degree. C. in a reducing atmosphere. During this process, Cu(OH).sub.2 and Cu-oxide are transformed into metallic copper powder, which contains the dispersoid. The dispersoid content of the copper powder is preferably in the range from 0.1 to 5% by weight.

摘要： The invention relates to novel organotin mercaptides and their preparation. The novel organotin mercaptides are particularly suitable as pesticides. In order to increase the biological activity and to ensure that there will be no damage to plants, a sulfur-containing organotin compound which constitutes the active ingredient of a pesticide consists of tricyclohexyltin alkanyl mercaptide or tricyclohexyltin alkenyl mercaptide. The alkanyl chain or alkenyl chain contains 6 to 25 carbon atoms and may be substituted and/or branched. The substituent may consist of halogen or the nitro group. The active ingredient of the pesticide consists particularly of tricyclohexyltin octyl mercaptide, tricyclohexyltin-2, 2-dipropylheptyl mercaptide, tricyclohexyltindodecyl mercaptide, or tricyclohexyltin undecenyl mercaptide. The agent is used for the control of acarina and insects, particularly mites and ticks.

摘要： An apparatus is described which serves for a pyrometallurgical processing of fine-grained solids suspended in high-oxygen gases, comprising a generally horizontally extending cylindrical vessel and a combustion shaft, which communicates with and vertically opens into the vessel which is provided with a gas outlet opening and with an opening for discharging molten material. An almost complete separation of the molten particles is effected in that the mouth of the combustion shaft tangentially opens into the vessel at the entrance of a spiral-shaped entrance passage, which opens into a discharge slot, which is formed in the shell of the vessel and which in the lower portion of the shell of the substantially cylindrical vessel extends substantially parallel to the longitudinal axis of the vessel.

摘要： A process is described in which hollow spheres or hollow-sphere composites (moldings) having high-strength walls are produced. Additional layers are applied to metallized spherical lightweight particles having a core of foamed polymer. In order to increase the strength of the wall of the spherical particle and the strength of the molding, metallized lightweight spherical particles having a metal wall thickness of 5 to 20 microns are treated (coated) with a dispersion of particulate metal or metal oxide or particulate ceramic or refractory material, the lightweight spherical particles coated in a thickness from 15 to 500 microns are dried, the dried particles are heated to a temperature of about 400.degree. C. to effect a pyrolysis of the polymer core, and the particles are subsequently sintered at a temperature from 900.degree. to 1400.degree. C.

摘要： A cathode for use in the electrolytic refining of copper which comprises a carrying bar and a flat starting plate, which is secured to the carrying bar and made of special steel and provided with electrically insulating edge strips at least at its vertical longitudinal edges, which are formed in their edge faces with a groove, which contains an edge strip, that is made of a natural or synthetic polymer and fits into said groove and protrudes from the edge throughout its length. To prevent a deposition of metal in the critical region, the insulating edge strip which has been fitted into the dovetail groove has been formed by a longitudinal folding of a polymer film and contains at its fold line a wire of special steel, and the side portions of said film are coextensive and lie one over the other and are liquid-tightly joined to each other. The invention relates also to a process of manufacturing the cathode.
