  • Patent number: 6858053
    Abstract: An exhaust system for housing-type enclosures of machine tools is provided for removing air by suction from the interior of the enclosure. The cuttings which are produced during machining of the workpieces are distributed within the working chamber and are thrown to the exhaust location and removed by suction. The cuttings collect in the exhaust area and present a safety risk. In order to prevent undesirable components in the exhaust air from reaching the exhaust system, an air-permeable catch device is provided in the exhaust area in front of the exhaust location. On the catch device, the undesirable components are caught while the exhaust action itself is not impaired. The catch device is a basket having walls made of mesh.

  • Patent number: 6814783
    Abstract: Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid. The filtrate substance can collect on or within the pores of the inorganic particles. Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.

  • Patent number: 6709499
    Abstract: An air-routing household appliance includes an improved removable and washable filter in that the filter is of a flexible fiber material and is finished such that it can bind and/or decompose odorous substances. Such a filter can be disposed, in particular, in the closed process-air circuit of a condensation laundry dryer to free laundry of unpleasant odorous substances. The odor filter is produced, in particular, from a textile material and can, therefore, advantageously be cleaned in a washing machine. For the binding of odorous substances, the fibers of the filter can be treated with particles that can bind odorous substances and from which the odorous substances can also be washed out again to regenerate the filter.
