Abstract: A mining auger includes an auger shaft having a front end, a conical end ring affixed to the front end of the auger and having a forwardly oriented face and a peripheral edge zone; a plurality of tool holders affixed to the peripheral edge zone in a circumferential distribution and each having a forwardly oriented face; and a cutting tool bit carried in each tool holder. Each cutting tool bit projects forwardly beyond a peripheral edge of the conical end ring and has a longitudinal axis extending at an inclined orientation with respect to an imaginary frontal plane which is perpendicular to the auger axis and which generally coincides with the mine wall face during operation. At least some of the tool holders carry a shearing tool bit each having an axis extending from the forwardly oriented face of the conical end ring in the direction of the frontal plane and further, each shearing tool bit has a tip which is at a significant distance from the forwardly oriented face of the respective tool holder.

Abstract: Addition products of water-soluble sulfites or disulfites to maleic acid mono- or diesters of partially fluorinated alkanols or the mono-, di- or triethyleneglycol ethers of these alcohols are useful as surface active agents, especially as wetting agents, as levelling agents in wax emulsions or as dispersants.

Abstract: In a blow-off device for limiting excess pressure in nuclear power plants, at least one condensation tube disposed so that a lower outflow end thereof is immersed in a volume of water in a condensation chamber having a gas cushion located in a space above the volume of water, and an upper inflow end of the condensation tube extends out of the volume of water and is connectible to a source of steam that is to be condensed or a steam-air mixture, the outflow end of the condensation tube, for stabilizing the condensation being provided with an assembly of wall parts forming passageways extending in axial direction for subdividing the steam flow and bubbles produced in the volume of water, the passageways of the assembly of wall parts being stepped in axial direction at both axial ends of the assembly of wall parts.

Abstract: New and valuable pesticide on the basis of an active ingredient from the group of organophosphorus compounds or chlorinated hydrocarbons, and additionally containing a thiol carbamate.

Abstract: An aqueous composition containing (A) an aminoplast precondensate, (B) a polymeric ethylene imine, the monomer of which is a reaction product of toluenediisocyanate a fluorinated alkanol and ethylene imine, which polymer is dispersed by means of a dispersant obtained by reacting said fluorinated alkanol, toluenediisocyanate and a polyethylene glycol, (C) a long-chain alkyl urea and (D) a cross-linking catalyst is useful for rendering a velvety suede-like polyurethane structure oil- and water-repellant.
