Abstract: An immersion pump is provided, the pump having an integral housing with an inlet opening on an intake side, an outlet opening on a delivery side, a passage for electrical lines, an electronic unit for processing power and optionally information signals, an electric motor, a pressure chamber and a pump unit. The electronic unit, the electric motor, the pressure chamber and the pump unit may be pre-assembled to an insert, with the pre-assembled insert being supported on one end of the housing. An axial clamping and/or fastening system, in particular a tapered locking arrangement, is provided on the opposite end of the housing.

Abstract: A device for the closure and/or protection of openings in structures has closure elements (10), which are arranged in such a way that they hang under running carriages (12) which can be made to move in a running rail (13). In the device according to the invention, each running carriage (12) has a bearing body (32) made of plastic, four running wheels (22) made of plastic, mounted on two parallel axes, and a sliding bearing (33) made of plastic and with good emergency running properties, assigned to each running wheel (22). This ensures that the closure elements (10) connected in a hinge-like manner are reliably folded together and unfolded.

Abstract: Thermoplastic elastomeric compositions, comprising blends of olefin rubber and polyolefin resin in which the rubber is cured with phenolic curative, exhibit superior properties including improved compression set and oil resistance.
