    Abstract: 1,152,825. Sportsground surfacing. BADISCHE ANALIN- & SODA-FABRIK A.G. 4 Oct., 1966 [5 Oct., 1965], No. 44195/66. Heading E1G. A sportsground, playground or footpath comprises an elastic layer of particulate closedcell plastic 13 between a filter layer 12 and a covering layer 15. The elastic layer is preferably a homopolymer or copolymer of styrene or ethylene in spherical particles bound by bitumen, rubber, polyisobutylene, or copolymers of acrylic acid or vinyl chloride or vinylidene chloride or open-cell expanded plastic, such that the layer remains water permeable. The covering layer may be waterbound with a layer of cinders 14 below or asphalt and chippings. Where the covering layer is laid hot, a layer of chippings may be used as a heat insulator. Where it is desired to control the water content of the elastic surface, it may be placed in a trough, lined with a sheet 10 of polyisobutylene, having a base layer 11 of water-permeable dispersion bound rigid foam and an outlet pipe 17 with different water level maintaining stand pipes 19, 20, 21.

    Abstract: 1,149,950. Coking; recovering hydrocarbon quench oils. BADISCHE ANILIN- & SODAFABRIK A.G. 31 Aug., 1966 [1 Sept., 1965], No. 38818/66. Heading C5E. Hydrocarbons and chlorinated hydrocarbons containing carbon black, e.g. obtained by washing hot gases, are recovered and particulate coke is produced from the carbon black by atomizing the hydrocarbons containing the carbon black and contacting the atomized material with a stream of hot gas to evaporate the hydrocarbons without cracking them. Hydrocarbons boiling in the range 140‹ to 350‹ C., e.g. propylbenzene, xylenes, naphthalene, and chloronaphthalene are mentioned and the hot gas stream should be free of oxygen, halogens and halohydrocarbons, examples being superheated steam, superheated hydrocarbon vapour, nitrogen, flue gas and cracked gas, and the maximum temperature is 800‹ C. A binder, e.g. resins, asphalt or bitumen, may be added to the mixture to be treated. The coke particles are separated from the gas/vapour stream and the hydrocarbons are recovered therefrom by conventional methods. Concurrent or counter-current contacting of the gas with the hydrocarbon may be employed, and in one embodiment (see Fig. 3, not shown), coking &c. is completed in a fluidized bed. The gas may be recycled after recovering the hydrocarbons therefrom. An example is described.

    Abstract: 1,125,403. Extruding polyamide sections. BADISCHE ANILIN- & SODA-FABRIK A.G. 7 Jan., 1966 [9 Jan., 1965], No. 776/66. Heading B5A. Polyamide rods 8 of various cross-sections are formed by ram extrusion of a supercooled melt of the resin through a cooled die 7. The term " supercooled melt " is defined as the state of the melt when at a temperature of 5-10‹ C. below its melting-point after polymerization, but before crystallization sets in. The extrusion process comprises two stages; in the first a mixture 2 of a lactam, catalyst and activator is homogenized by means of a plate 1 within a mixing vessel heated to the polymerization temperature, and in the second the mixing vessel is placed within barrel 6 of the extruder where anionic polymerization takes place and the bottom 3, Fig. 1, or 10, Fig. 2, of the vessel, which is movable, is acted upon by a ram 11. The preferred range of polymerization temperatures is 100-140‹ C. and that for extrusion is 180-210‹ C. According to the invention the rods have a monomer content of less than 1À2% by weight and a water absorption of less than 50% by weight and the rods may be stretched by rollers or a sizing die to increase their strength. Gearwheels may be made from the rods. Numerous lactams, activators and catalysts are listed as well as conventional additives. An example is given.

    Abstract: 1,046,552. Steam traps &c. BADISCHE ANILIN- & SODA-FABRIK A.G. Feb. 19, 1964 [Feb. 20, 1963], No. 6879/64. Heading F4U. A thermally controlled condensate discharger comprises thermal bimetallic control means controlling a valve having a stem 11 and having a plate 15 on the outlet side of the valve seating 22 of valve body 4, which plate forms a gap 23 with valve body 4, the diameter of the plate being at least twice that of the valve passage 12. Condensate and steam pass through passage 7, chamber 9 enclosing the bimetallic plates, passages 10, 11, 12 in the valve body and out through chamber 20 adjacent the plate 15 and outlet 21. The valve is opened by the temperature effect on the bimetallic plates 17 and pressure in chamber 9. As condensate passes through the gap between valve plate and body the change of pressure causes the formation of steam in the gap which assists opening. The plate and stem may be joined by a conical part, the plate and seating may have curved surfaces and the gap may widen outwardly.
