  • Patent number: 6197707
    Abstract: An improved bituminized flame-retardant textile material is provided that effectively overcomes bitumin adhesion difficulties associated with products of the prior art wherein the flame-retardant present on the surface of a textile support interfers with and hinders the achievement of bitumin adhesion. An anti-flame agent is applied in a quantity of 20 to 100 grams per square meter over 30 to 90 percent of the upper surface of the textile support. The remaining portions of the upper-surface of the textile support are free of the anti-flame agent. It surprisingly has been found that the surface portions of the textile support that are free of the anti-flame agent provide areas for the achievement of optimum bitumin adhesion with the textile support while still making possible entirely satisfactory flame retardancy for the overall product.

  • Patent number: 6114262
    Abstract: Disclosed is a base inliner comprising a textile sheet material and a reinforcement, wherein said reinforcement absorbs a force so that, in a stress-strain diagram (at 20.degree. C.), the load at an elongation within the range between 0 and 1% differs by at least 10% at at least one location for said base inliner with said reinforcement compared with said base inliner without said reinforcement, preferably by at least 20%, particularly preferably by at least 30%. The base inliner is useful for producing optionally bituminized roofing and sealing membranes.

  • Patent number: 5714171
    Abstract: Apparatus for drawing filament bundles present in the form of a curtain comprises an injector which is rectangular in horizontal section and which is adjoined by a drawing shaft in the form of two parallel plates. At least one of the plates comprises a plurality of pressure measuring elements arranged in the form of a grid whereby the velocity distribution of the drawing gas in the drawing shaft can be adjusted through local variation of the geometry or the amount of drawing gas in the drawing shaft.

  • Patent number: 5569865
    Abstract: A method for monitoring the gas flow rate through injector jets comprises determining the pressure in a drawing tube downstream of the injector jet. The injector jet comprises a feed funnel extended by an injector tube opening into a gas distributor chamber having a gas feed line. The chamber is connected by a curved surface of revolution to an outlet duct. A drawing tube is downstream of the outlet duct, and both the outlet duct and the drawing tube have longitudinal axes that coincide with one another. The downstream end of the injector tube is situated at the junction of the outlet duct with the curved surface of revolution. The drawing tube has a pressure measuring device.

  • Patent number: 5370833
    Abstract: A process produces fibers from polymers which give off troublesome gases and/or vapors during spinning, comprising the steps of:a) extruding the molten polymer through a spinneret into a closed spinning shaft,b) quenching the resulting filaments in the spinning shaft with a gas,c) taking off the resulting filaments from the spinning shaft,d) conducting the quench gas away from the spinning shaft and introducing it into a gas purification system ande) purifying the used quench gas by contact with an adsorbent for said troublesome gases and/or vapors.It is possible by the present invention to keep hazardous gases occurring during the spinning of polymers away from the surroundings and to dispose of them. Suitable polymers are in particular polyphenylene sulfides.
