Abstract: The present invention relates to a multiple layer composite material and to a method for producing the same. Said multiple layer composite material has at least one layer of cement-bound concrete and at least one layer of polymer-bound concrete. The transition between adjacent layers of cement-bound concrete and polymer-bound concrete has at least the material strength of the less stable one of the concrete layers adjoining the transition. The layer of polymer-bound concrete allows the diffusion of water vapor, but does not allow liquid water to penetrate. The multiple layer composite material can be produced completely in an aqueous system.

Abstract: A hydraulic chain tensioning means for automatically tensioning the chains of crawler vehicles equipped with two-, four- or eight-wheel articulated suspension means comprises essentially two tensioning cylinders (1.1 and 1.2) and a plurality of valves (3). The two tensioning cylinders (1.1 and 1.2) are interconnected by way of ducts (4) and connected by further ducts (5) to the valves (3). The tensioning cylinders (1.1 and 1.2) are fitted to the chassis (10) of the crawler vehicle and the leading wheel of the crawler vehicle bears against the piston rods (1.1K and 1.2K) of the tensioning cylinders (1.1 and 1.2). Parallel to the tensioning cylinders (1.1 and 1.2) a soft spring (piston-type accumulator 6) is connected so that at the beginning of the chain tensioning means being put under load only a minor pressure rise occurs in the tensioning cylinders (1.1 and 1.2).

Abstract: An air filter for use in filtering air entering an operator's cab of a human-operated machine. A fine mesh screen and air permeable fibrous cover are added to the air outlet side of a conventional air filter. An accordion-shaped filter element of the conventional filter is located upstream of the fine mesh screen. Granular filter material such as activated charcoal fills the space between the accordion-shaped filter element and the fibrous cover. An air-impermeable strip may be added at the top portion of the fine-mesh screen across the full width of the air filter to prevent air from flowing through a void in the granular filter material which may develop over time due to settling.
