Abstract: The present invention encompasses a method of selectively separating Ga from wastewaters with the aid of a dialysis method. This exploits the particular complexation behaviour of Ga, which forms an unstable tetrahalo complex. This forms only in the case of a sufficiently high halide concentration. Since the halide concentration becomes lower across the membrane, the Ga-tetrahalo complex breaks down in the membrane, as a result of which the Ga is retained. Other metals such as In and Fe do not show this behaviour, and therefore the tetrahalo complexes of these metals can pass through the membrane and hence can be selectively separated off.

Abstract: An air filtration system for purifying an air stream, such as the intake air for an internal combustion engine, including a system plate (10), an unfiltered air zone (13), a filter housing (12) containing a filter element (16), and a filtered air zone (19). The filter element hermetically seals and separates the unfiltered air zone (13) from the filtered air zone. The unfiltered air zone (13) is configured by a first half shell (11), which is connected to the system plate (10) in a fixed, hermetically sealed manner. The filter housing (12) is also connected to the system plate in a fixed and sealed manner. The permanent, air-tight connection of the first half shell to the system plate allows the air filtration system to be manufactured in a simpler, more rapid and more cost effective manner by obviating the need for seals and connecting elements, as well as the need to assemble such parts.

Abstract: A filter including a housing made up of two housing shells in the form of mating cylindrical vessels (12, 12a) in one of which a support tube (17), especially a support tube having a conical shape, is integrated. A conical annular filter cartridge, preferably one having a resilient axial play compensating element (21) at one end, is installed on the support tube (17). The housing shells (12, 12a) are joined by a central screw connection (22), and sealing between the housing shells is effected by a labyrinth seal (14, 15). The filter is able to adapt to tolerance variations in the axial length of the individual components, so that productions costs are kept low. The housing shells (12, 12a) are constructed in such a way that they can be manufactured using simple casting molds with no undercuts.
