    Abstract: The present invention relates to a process for the production of concentrated, water-soluble or water swellable emulsion polymers by the polymerization of at least one water-soluble monomer in a water-in-oil dispersion by means of polymerization initiators, preferably in presence of bi- or multi-function vinyl- or allyl compounds in which a water-in-oil dispersion of the starting monomers is polymerized while being stirred so that the heat of polymeriaation is eliminated by distillation removal of the water contained in the reaction mixture. The polymerisation temperature is preferably adjusted and controlled by means of the pressure in the system.

    Abstract: An additive for deep-well cement slurries comprising a water-soluble anionic copolymer having a molecular weight from about 50,000 to 500,000 and comprising about 1 to 60 mole % of anionic structural units and about 99 to 40 mole % of nonanionic structural units. A preferred additive comprises a terpolymer of acrylamide, sodium acrylate and sodium vinylsulphonate. The additives retard the setting action of the slurry, stabilize the slurry, prevent the swelling of readily hydratable clays and are resistant to electrolytes which would accelerate setting and seepage of water from the slurry.

    Abstract: A pair of pipes have respective end portions one of which is received within the other and defines therewith an annular clearance. Two axially spaced sealing elements are sealingly accommodated in the clearance, and an opening in the outer one of the end portions communicates with the clearance intermediate these sealing elements. A body of hardened material, which was admitted in flowable state via the passage, is accommodated in and fills the clearance intermediate the sealing elements to thereby unite the pipes in stress-transmitting contact with the end portions.

    Abstract: This invention relates to gels consisting of the reaction product of water-soluble polymers of poly(meth)acrylic acid derivatives and multivalent metal salts, in which connection such gels are characterized by the fact that they consist either of the reaction product of a W/O dispersion of the water-soluble polymers with water-soluble solutions of the metal salts, or of the reaction product of aqueous polymer solutions with W/O emulsions of the metal salts. Further, the invention relates to a process for the production of the gels, as well as their use to seal or consolidate permeable soluble materials and to form mortar type combining masses.

    Abstract: A process is disclosed for the rapid dissolution of water-soluble polymers in water, in that water in a finely divided state is introduced under pressure into the prepared finely divided polymer. The water-soluble polymer can be in the form of a water-in-oil emulsion or the form of a powder-in-oil suspension; the water is preferably introduced under pressure through a nozzle and tangentially to the surface of the prepared polymer.

    Abstract: An electromagnetic relay has a bar-shaped armature which is mounted at one end at a coil flange in a carrier comprised of insulating material, in which center contact blades are also mounted at opposite sides of the armature such that movement of the armature is transmitted to the contact blades through the carrier, thus eliminating the plunger which is normally present for contact actuation. The offset positioning of the contact blades with respect to the armature in the carrier causes friction which substantially prevents damaging impact of the contact pads of the contact blades with respectively mating stationary contact pads.
