  • Patent number: 7877819
    Abstract: The invention relates to protective clothing with a protective function against chemical and/or biological contaminants, especially for civil or military purposes, such as NBC protective clothing, with the protective clothing having a multiple-layer construction or a multiple-ply textile construction with an outer material and an inner material equipped with a protective function against chemical and/or biological contaminants, with the protective clothing being provided with at least one ventilation opening that is closed with a gas-permeable, in particular, air-permeable protective filter material that sorbs chemical and/or biological contaminants. In this way, when the clothing is being worn, the air supply and the air exchange is increased in an efficient way and the removal of moisture, in particular, sweat, and also excess body heat, is improved and thus the overall comfort in wearing the clothing is increased, without negatively affecting the protective function of the clothing.

  • Patent number: 7866977
    Abstract: The subject of the invention is a rotary tube (1), in particular for a rotary tubular kiln for the production of activated charcoal, according to the invention the rotary tube (1) being provided on its outside with at least one reinforcing element (8) for stabilizing the rotary tube (1) in the operating state. As a result, the rotary tube (1) exposed under operating conditions to high temperatures and consequently easily deformable is stabilized in its cross section and/or in its longitudinal direction, depending on the arrangement of the reinforcing element. In particular, the rotary tube (1), for example when it is used for the production of activated charcoal, with the accompanying high operating temperatures, is equipped with efficient resistance to pronounced pressure fluctuations occurring due to the method employed and is therefore also suitable, in particular, for carrying out processes under reduced or increased pressure.

  • Patent number: 7811083
    Abstract: The invention has as subject matter a rotary tube, especially for a rotary tube kiln for the production of carbon, with several mixing elements arranged in the inner space of the rotary tube for a thorough mixing of a charged material. The rotary tube comprises a transitional area from a smaller inside cross section to a larger inside cross section of the rotary tube. The mixing elements are formed in the transitional area and/or are arranged in such a manner that the charged material is transported during operation by the mixing elements toward the smaller inside cross section. The result is an excellent thorough axial mixing and blending of the charged material, which results in an increased homogeneity of the activated carbon produced.
