In this manner, the oil use of the internal combustion engine greatly increases. With the device of the present invention, the oil collected on the refined gas side is collected in a liquid storage unit (10), whereby the liquid storage unit (10) is protected from the stream, so that the gas stream can not carry away oil any longer. The device includes a support body (9), which is impermeable to the stream by means of a cut-off wall (23), in order to prevent a carrying-off of the oil.

  • Patent number: 6723157
    Abstract: A material is provided for capturing a chemical substance comprising fibers which carry metal alkoxide particles on the surfaces thereof. The metal alkoxide particles are made from an oligosilica, an oligozirconia, an oligotitiania, or the like. The fibers may include inorganic fibers, regenerated fibers and/or synthetic fibers. The material for capturing a chemical substance is produced by a method comprising steps of subjecting the fibers to a surface treatment for facilitating adhesion of the metal alkoxide particles to the surfaces of the fibers, forming the metal alkoxide particles on the surfaces of the fibers, and fixing the metal alkoxide particles to the surfaces of the fibers. A chemical substance-capturing tube, capable of capturing a trace of a chemical substance in a liquid or a gas, can be produced by placing the fibers, i.e., the material for capturing a chemical substance, in a hollow tube.

  • 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.

  • Patent number: 6454827
    Abstract: A filter medium has a function member accommodated between two fiber layers. A production method for manufacturing a filter medium includes the steps of: preparing a first fiber layer having a shape identical to that of a side surface of the filter medium; disposing a function member on a surface of the first fiber layer; and forming a second fiber layer by spinning partially melted fibers onto the function member disposed on the surface of the first fiber layer. Therefore, it is unnecessary to carry out press-forming in a state in which the function member is sandwiched between nonwoven fabrics, and a countermeasure to prevent the function member from falling out and a countermeasure to prevent the nonwoven fabric from being torn by the function member are unnecessary.
