Abstract: The invention concerns a filter insert (1) that is provided as an exchangeable insert in a filter, in particular an oil filter, fuel filter or the like of an internal combustion engine. The filter comprises a filter housing (3) that can be separated along a separating plane (2) and the exchangeable filter insert (1) extending in an axial direction (18). Two housing parts (4, 5) of the filter housing (3) are sealed relative to one another along the separating plane (2) by means of a seal (6). The seal (6) is secured slidably and captively in the axial direction (18) on the filter insert (1).

Abstract: A filter composed of a filter medium (10) formed from a corrugated filter layer (11) and a flat filter sheet (12) which are interconnected by embossing points (15). This eliminates the need for an additional joining agent. Production of the filter is simplified because no additional materials are required to be supplied or cured.

Abstract: The invention concerns a method for producing a ceramic filter body (1) for filtering an exhaust gas stream (2) of a diesel engine. The filter body (1) has planar and porous filter sections (3) that are designed to be passed by the exhaust gas flow (2) in a direction transverse to the face of the filter sections (3). A planar permeable fiber web (4, 4?), in particular of filter paper, is first impregnated with finely ground ceramic material (6) only across sections under formation of a non-impregnated section (12). The only partially ceramic-impregnated fiber web (4, 4?) is subsequently brought into the shape of a blank of the filter body (1) in such a way that the impregnated areas of the fiber web (4, 4?) assume the shape of the filter body (1).

Abstract: Mud wings of the present invention include an enclosed space in which water diverters are disposed in positions and in orientations that cause water entering the enclosed space through the front panel of the mud wing to directionally drain to a predetermined exit port in the mud wing. In one embodiment, the exit port is located on the bottom portion of a thin sidewall of the mud wing that is designed to release water on the inboard side of the tire path, which prevents the water from being deposited into the path of any rearward tires.

Abstract: A device is used for controlling an installation that is comprised of several units. A common control system, that is provided with a central data memory, in which current real values and/or set points are filed as process variables for several units, is allocated to several of these units. The data memory encompasses a storage area for the process variables. The data structure of this storage area can be configured even by using a set of data that describes the projected installation.

Abstract: The flow machine is furnished with an abradable (10) made of a particle composite material. This so-called composite (1) contains granular core particles (2) of a ceramic material. The surfaces (20) of the granular core particles carry functional layers (22) which form an intermediate phase of the composite which is stable at a high operating temperature. The intermediate phase in this process has been produced in situ at least in part by a chemical reaction of a precursor material (22?) and material (21) of the granular core particles on the particle surfaces (20). Bonds (23) are formed between the granular core particles arranged in a porous composite by the intermediate phase. These bonds have a breaking characteristic for abradables.

Abstract: A method for determining substrate and product concentration in liquid and/or gaseous media is disclosed. The analytes are removed by time-controlled diffusion of at least one analyte between the medium and a diffusion medium which is fed to the sampling regions through fluid conduits using at least one pump and semipermeable membranes. The diffusion medium is transported to at least one detector, while simultaneously new diffusion medium is fed from the sampling region and analyzed to determine the analyte concentration. The pump operates continuously and the diffusion medium is fed to the fluid conduits in alternation through a multivalve or multipath valve connected in series upstream from the sampling regions. The detector and the pump are additionally connected through a bypass conduit joined to the valve, and the detector is continuously fed diffusion medium through the fluid conduits and the bypass conduit.
