    Abstract: 1,053,757. Olefin polymer/bitumen compositions. BADISCHE ANILIN- & SODAFABRIK A.G. Oct. 24, 1963 [Oct. 31, 1962], No. 41962/63. Headings C3N and C3P. A moulding material is produced by causing molten bitumen, having a penetration of at least 35, to flow in a stream and extruding into the bitumen, in the direction of flow thereof, strands of molten polymer of a mono-olefin. The polymer may be derived from ethylene, propylene, butene, isobutylene, with/without vinyl acetate, vinyl propionate or an acrylic ester. Optionally a mineral filler is present in the polymer and specified are ground shale or slate, quartz powder, clay and feldspar. Further, the polymer may be used in the form of a concentrate in the bitumen. Preferably the extruding apparatus comprises 2 to 20 jets per kilogram per hour of polymer, and the stream of bitumen has laminar flow downstream of the jets. Applications specified for the moulding material are as coatings for metal surfaces, as sealing compounds, and as pipes and road surfaces.

    Abstract: 734,258. Contacting liquids with gases. BADISCHE ANILIN- & SODAFABRIK AKT.-GES. Dec. 21, 1953, No. 35451/53. Class 55 (2). A gas-liquid contact column comprises a series of horizontal contact platforms arranged one above the other in a column down which liquid is passing wherein each platform is sub-divided into sector-shaped or annular sections in such a way that imperforate section is followed by a gas permeable section through which a gas is passing upwardly and which is followed in turn by an open section allowing free passage of liquid on to the platform below, if desired a weir being provided at the free edge of the imperforate section to determine the level of liquid on the section and a downwardly projecting extension of the weir depends into liquid on a lower platform. As shown in Fig. 2 which is an expanded drawing of a portion of a column comprising three platforms A, B and C, each platform having sector-shaped imperforate sections a and e, perforate sector-shaped sections b and f and open sector-shaped sections b 1 and f 1 . Weirs c and g are provided in sections band f, downward extensions of the weirs providing a retaining wall d for liquid on the imperforate sections a and e of platform B and depending into liquid on the platform C and forming a gas seal preventing gas by-passing portions of the column. In a modification when a large volume of liquid is fed to the apparatus the weirs c and g are dispensed with, the retaining walls d finishing flush with the surface of the perforate sections b and f. In a further modification the various sections are annular, the liquid flowing from the periphery of the platform towards the middle of the platform on one platform and vice versa on the succeeding platform.

    Abstract: 1,149,033. Coating with metals. BADISCHE ANILIN - & SODA-FABRIK A. G. No. 31866/66. Headings C7B and C7F. In an electroless process for coating a plastics sheet with copper or silver in which the plastics surface is first coated with iron powder in a binder, the binder contains at least 20% by weight of a polyisocyanate. The binder may also include vinyl copolymers, polyvinyl chloride, acetal, formal or butyral or soluble polyamide. The coating may be applied through a stencil, and the powdered iron coating may be annealed at a temperature up to 60 ‹C. prior to deposition. A bath for depositing copper may comprise (g./l.) 150 copper sulphate, 40 triethanolamine, and 27 sulphuric acid. A silver layer may be deposited on the copper using a bath comprising 1À5 silver nitrate, 3 E.D.T.A., 3 sodium thiosulphate, and 2 tartaric acid. The copper surface may be electro-plated with a further layer of copper, using the same bath as for the electroless-plating, and then with Cr, Ni, Co or Rh, and the copper or silver surfaces may be electro-plated with Fe, Ni or Co or mixtures thereof.

    Abstract: 1,094,254. Polymerizing in a mould. BADISCHE ANILIN- & SODA-FABRIK A.G. March 5, 1965 [March 7, 1964], No. 9403/65. Heading B5A. In a process for making thermoplastic articles by polymerization in a mould, use is made of a jacketed mould 2, Fig. 1, having top and bottom walls 3 and 1 which support a rotatable hollow core 4. The mould walls are preheated to a temperature below the maximum temperature occurring during polymerization and the core is rotated to generate a velocity gradient across the thermoplastic material. To produce profiles the reactants are introduced into the chamber 28, Fig. 5, defined by the rotating core 27 and the wall surface 26. An ultra-sonic vibrator 29 is located at the outlet 25 from which the moulded article is withdrawn by support means 31.
