Abstract:
A valve, especially a gas safety valve includes a fluid-guiding path (32) that can be sealed by a sealing device (30) provided with a sealing surface (34). The sealing surface can be brought against an abutment surface (36) of an abutment part (38), and is at least partially inserted into a receiving region (40) of a receiving part (42). As the sealing device (30) is fixed inside the receiving region (40) in such a way that a counter-holding part (54) can be brought into contact with the sealing device (30) by connection to the receiving part (42), the sealing device is arranged inside the receiving region of the receiving part and is securely held in the receiving region.
Abstract:
A composition for coating metal surfaces based on crosslinking polyester resins as an organic constituent, which, based on its total mass, contains from 4 to 20% by weight of aluminum flakes and not more than 0.1% by weight of compounds containing isocyanate groups. The composition preferably comprises, as an organic binder, at least one hydroxylated polyester resin, preferably having a mean molar mass in the range from 2000 to 15,000, a crosslinking component for the hydroxylated polyester resin and an acidic crosslinking catalyst. A process for applying the composition to metal strip in a belt process is likewise disclosed. The layer application is adjusted within the range from 3 to 30 μm according to the end use, for which double coating may be advantageous. For example, the composition may serve as a “galvanization replacement”.
Abstract:
Synergistic crop plant-compatible herbicidal compositions comprising herbicides from the group of the benzoylcyclohexanedionesHerbicidal compositions comprising A) a compound from the group of the benzoylpyrazoles, B) at least one further herbicide and C) at least one safener are described as herbicides which are active against monocotyledonous and/or dicotyledonous harmful plants. Compared to the herbicides used on their own, these compositions have superior activity and at the same time high compatibility with crop plants.
Abstract:

Abstract:
The plastic toy building block is provided with electrical contacts to determine its position. The block has a basic body having recesses extending from top to bottom in its interior. In these are each inserted, combined into packets, several discrete elastically resilient conductor wires clamped between plastic strips. Elastically resilient conductor wires protrude downward into the recess. Contact points protrude from the plastic strips at the top. Several electrical cables are led from each nub to the underside of a nub plate to discrete contact points. Except for the nub surfaces, the nub plate can be covered by a cover plate and hereafter can be placed with the nub plate on the basic body of the toy building block. The lower contact points on the film then make electrical contact with the upper stubs and thus with contact points of the conductor wires.
Abstract:
An internal combustion engine with an exhaust gas manifold, an exhaust gas line, an exhaust gas turbocharger, by which the compressor provided to charge combustion air for the internal combustion engine is driven, and a bypass line, which branches from the exhaust gas line and in which a power turbine is arranged, wherein a short-circuit line branches from the bypass line and leads to a section of the exhaust gas line located downstream of the exhaust gas turbocharger. In addition, a first valve is positioned in the section of the exhaust gas line located downstream of the exhaust gas turbocharger in such a way that exhaust gas leaving the exhaust gas turbocharger is diverted into the short-circuit line and then to the power turbine.
