Abstract: A device is provided, designed as a jet pump, and having a gas generator to generate a flow of compressed gas, wherein the gas generator is equipped with a pyrotechnic propellant charge designed as a cutting or shaped charge. This pyrotechnic propellant charge can serve to generate a shock wave, as a flow of compressed gas, from the combustion gases of the propellant charge. The device is equipped with an inlet port of an inlet duct, which inlet port is arranged in the region of the smallest cross section of a venturi nozzle, such that surrounding air is sucked in through an exhaust port of the inlet duct as a result of the suction that arises. This difference in pressure can be used for various purposes.

Abstract: A threshing drum includes beater arms which are arranged on a circumferential surface of the threshing drum so as to be movable relative to a threshing concave that is disposed adjacent to the threshing drum. At least one of the beater arms is equipped over a periphery thereof with at least one beater body that is movably drivable relative to the at least one of the beater arms.

Abstract: A tiltable ashtray, e.g. for motor vehicles, includes an ash receptacle, a support housing for a lighter and a lighter which are removably disposed in a receiving housing that is tiltably pivotally supported in an external frame receivable in a recess. The ash receptacle, receiving housing and lighter can be removed from the receiving housing and replaced with a storage bin. Detachable clip connectors hold those elements in the receiving housing enabling the bin to replace the other elements, and vice-versa. A contact assembly on a circuit board in the receiving housing is connectable to an electrical system. It includes an electrical contact for the cigarette lighter and an additional contact connection to an electric light in the receiving housing.
