  • Method for the production of fire-resistant wood fiber moldings
    Patent number: 7858005
    Abstract: The invention relates to a method for the production of fire-resistant dense moulded pieces made from wood fibers, mixed with water glass as a binding flame-protection agent at a temperature above ambient temperature. A non-woven fiber formed from the above mixture is compressed to a density of <350 kg/m3 and then the hardening of the binding flame protection agent carried out in a closed press in the compressed state at temperatures above 80° C.
    Type: Grant
    Filed: September 2, 2003
    Date of Patent: December 28, 2010

    Inventors: Volker Thole, Dirk Kruse
  • Composition for a fire-protection agent for materials and fire-protection method
    Patent number: 7828995
    Abstract: The invention relates to novel compositions for fire-protection agents for materials, to a method for treating materials for protection against fire, and to the use of the compositions as fire-protection agents. More precisely, the invention relates to compositions for a fire-protection agent, such as a fire-protection paint, for materials, characterized in that ceramizing additives and volume-builders are contained as ingredients.

  • Heating wall for coke-oven battery
    Patent number: 4565605
    Abstract: A pair of adjacent horizontal coking chambers of a coke-oven battery are separated by a longitudinal wall with a multiplicity of vertical heating ducts, the wall being built from blocks which form two parallel frameworks defining the ducts between them. Each framework consists of longitudinal and transverse refractory blocks--preferably of silica--leaving rectangular apertures open toward the ducts and the chambers, these apertures being occupied by refractory plates of lower thermal resistance than the blocks. The transverse blocks of the two frameworks extend overlappingly between the ducts and have interfitting formations holding the frameworks together.
