Abstract: A turbine blade for turbo-engines as well as a method for manufacturing such a turbine blade is disclosed. According to the task set, the turbine blades should be capable of withstanding high thermal stress and able to maintain an adequate mechanical strength even at raised operating temperatures. The turbine blades are so designed that on the surface of a core element a heat-insulating layer of a metallic open-cell foam is integrally connected to said core element by sintering. The outer contour of the turbine blade is formed with at least one shell element. The shell element comprises a nickel-base alloy, which is also integrally connected by sintering to the open-cell foam which forms the heat-insulating layer.

Abstract: Protective layers of the MCrAlX type according to the prior art are often provided with a platinum layer to prevent diffusion of elements out of the base material into the MCrAlX. The MCrAlX alloy according to the invention includes halogens (F, Cl, Br, I), which prevent this diffusion, in particular of titanium.

Abstract: A windshield wiping device for swivelling windshields of motor vehicles. The device includes a wiper shaft, which is supported on the assembly adjacent to the swivel axis of the windshield, and a wiper arm projecting over the windshield. The arm includes an attachment part, by means of which it is attached to the wiper shaft, and a pivoting part which can be swivelled relative to the attachment part around a swivelling axis, and which, by means of an electrical motor is brought into a stopping position on the windshield, in which the electrical motor is independently switched off by means of a stopping position switch. In order to open the windshield without damage, in the stopping position, the swivelling axis, between the attachment part and the pivoting part of the wiper arm, is directed at least approximately in parallel to the swivelling axis of the windshield.
