Abstract: A shaft seal for a transmission expander or compressor having at least one rotor which rotates in a housing and is arranged in a floating manner on a shaft, the shaft seal having a seal arrangement with seal tips attached on the hub of the rotor. A stationary sealing ring surrounds the seal tips which are arranged in three seal sections. An annular chamber is arranged between in each adjacent pair of seal sections. The annular chamber which faces the interior of the transmission expander or compressor is equipped with a feed means for a sealing gas, the pressure of which is higher than the pressure in the interior of the transmission expander or compressor. The annular chamber which faces away from the interior of the transmission expander or compressor is provided with an extraction means for the sealing gas.

Abstract: A convertible vehicle including a folding top frame constructed in mirror-image fashion to a longitudinal median plane of the vehicle and having a rear folding top clamping collar. The folding top clamping collar can be shifted jointly with a folding top about a main bearing fastened to the car body and stowed in a rear folding top compartment. The flexible roof skin has, in the rear region, a rear window which extends above the folding top clamping collar and can be detached in the region of the lower transverse side edge from the folding top clamping collar. The rear window is supported in the closed position with its lower transverse side edge directly above and on the folding top clamping collar. A control assembly is linked to the frame encompassing the rear window in U-shaped fashion such that the frame with the rear window can be lifted from the folding top clamping collar during a movement of the folding top and shifted to a distance and an angle relative to the folding top clamping collar.

Abstract: A convertible vehicle has a folding top frame (3) with a rear folding top clamping collar (4; 4′; 4″), which is constructed in mirror image fashion to the longitudinal median plane (2) of the vehicle. By being shifted about a main bearing (5) attached to the car body, a folding top (7) can be stowed in or returned from a rear folding top compartment (8). The flexible roof skin (6) has in the rear region particularly a dimensionally stable rear window (9) with an essentially rectangular circumferential contour, which extends above the folding top clamping collar (4; 4′; 4″). Only in the region of the upper transverse side edge (10) as well as of its two longitudinal side edges (11, 12) is the dimensionally stable rear window (9) provided with a connection taking hold of the flexible roof skin (6).

The flexible roof skin (6) has, in the rear region, a rear window (9), which extends above the folding top clamping collar (4), especially is dimensionally stable and can be detached in the region of the lower transverse side edge (13) from the folding top clamping collar (4). Pursuant to the invention, the rear window (9) is supported in the closed position with its lower transverse side edge (13) directly from above on the folding top clamping collar (4).

Abstract: A hot gas-carrying gas collection pipe (1) of a gas turbine, which is arranged between the combustion chamber and the turbine blades. The gas collection pipe (1) has two inlet openings (2) for receiving the hot gas. The outlet comprises the flanges (5, 6), which are connected to the turbine. The material of the gas collection pipe (1) is a high-temperature- and corrosion-resistant base metal (9) with a high-temperature corrosion and oxidation coating (4) applied to both the inside and the outside of the base metal (9). In the area of the inner cone (13), an HTCO coating (4) is applied to the base metal (9) on one side and a thermal barrier coating (8) is applied on the opposite side.
