  • Patent number: 7494558
    Abstract: Composites made from at least two plies are described, where one of the outer layers is a layer comprising glass fibers, and in particular is a staple glass fiber nonwoven. The layers have been bonded to one another by needling, and the extent of this needling is such that some of the fibers of the organic nonwoven emerge from the surface of the glass fiber sheet. The composite is then provided with a binder by using a rotating roll for single-side application to the glass fiber surface. The composites are particularly suitable for producing bituminized prefabricated roofing and waterproofing sheets, and as backings for coatings, e.g. PVC coatings.

    Abstract: In accordance with the invention, a laminate of two or more layers and the method of making it is provided. The laminate includes at least one organic synthetic filament non-woven layer, and at least one woven web or scrim of glass fibers pre-consolidated by a binding agent. The polyester non-wovens and the woven webs or scrims are bound by needling such that a part of the (e.g., polyester) filaments penetrate through the laminate and emerge at the lower surface of the laminate and lie adjacent thereto The formed laminate is subjected to a final consolidation by an acrylate or a styrene binder.

  • Patent number: 7199065
    Abstract: The present invention provides non-woven laminate that is not subjected to final consolidation by a binder and the production thereof. The laminate includes at least one non-woven mat containing glass staple fibers pre-consolidated with a resin, and at least one non-woven layer of synthetic fibers. The synthetic non-woven layers and the pre-consolidated non-woven mat of glass fibers are bounded together by needling such that a portion of the fibers of the upper synthetic non-woven layer passes through the non-woven mat of glass fibers possibly through the underlying synthetic non-woven layer. The synthetic fibers are heat shrunken and the laminate is binder free.

  • Patent number: 7129788
    Abstract: A d.c. signal controlled oscillator includes a frequency-determining network having a control input and a modulation input. A phase regulating loop includes the oscillator and components that provide a control signal to the control input. A circuit apparatus for driving the oscillator includes a modulation generator that provides a modulation signal to the modulation input, and a circuit arrangement that autonomously generates a signal depending on and representing a slope of the modulation and provides this slope signal to the modulation generator, which generates the modulation signal dependent on the slope signal.

  • 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: 5319131
    Abstract: Esters of .alpha.-fluoroacrylic acid are accessible by hydrolysis of an .alpha.-hydroxymethyl-.alpha.-fluoromalonic acid ester, decarboxylation and dehydration of the hydrolysis product and subsequent esterification of the resulting .alpha.-fluoroacrylic acid with an alcohol. The esters are polymerizable and are suitable for use as a starting material for preparing fluoropolymers which in turn are usable as materials for manufacturing transparent articles. The polymers are high-molecular and non-crystalline and have softening temperatures of above 100.degree. C.
