Abstract: A heat exchanger has a first tube bundle for circulating a first fluid, a second tube bundle for circulating a second fluid, and a shell which accommodates the tube bundles arranged in series in the shell, so that when a third fluid is circulated through the shell it successively contacts the tube bundles for a successive heat exchange between the third fluid and a respective one of the two first-mentioned fluids, to provide a heat transfer between three fluids.

Abstract: The method is to developed a two-phase flow in the circulation circuit. This method is defined by the fact, that a two-phase flow is developed by means of hydrogen introduction into the coolant. Hydrogen can be introduced in mixture with an inert gas or water steams.

Abstract: The invention is based on the principle that the antitheft device has a body of a hard material which cannot be easily cut through and which covers the points of connection of at least one rib with the steering wheel rim and the steering wheel hub. As a result, even though the uncovered rim portion or uncovered ribs are cut through, the device still preserves its antitheft functions, and the vehicle remain non-steerable. The body of the device has a U-shaped cross-sectional configuration so that the device can be hooked up over the wheel rim and then locked to the rim by a lock.

Abstract: In a method of and a device for suction transporting a material from an object surface, the suction transporting device has a suction unit and a unit for modulating the suction. A suction is applied to a transporting line by the suction unit so that a material is transported through the transporting line from an inlet to an outlet. A suction force of the suction produced in the transporting line is modulated by communicating an interior of the transporting line with atmosphere through a passage and periodically changing the area and the shape of the passage during the transporting. The frequency of the modulation is changed in dependence on the distance between the inlet of the transporting line and the object surface.
