Abstract: Articulated part (1) for a stand (2) with an axially rotatable and vertically swivelable articulated arm (3), wherein the articulated part (1) has a pivot pin (6) which can be connected with a carrier (5) by a connection part (4), and wherein the articulated part (1) has a tilting joint (7) for the articulated arm (3), wherein it is provided according to the invention that the articulated part (1) is essentially formed of a one-part plastic injection-molded part (1.1), wherein the tilting joint (7) has two bearing disks (8) formed of sheet metal which have an opening (9) roughly in the center, wherein the bearing disks (8, 8) are embedded parallel to one another at a distance (A) in the plastic injection-molded part (1.1), wherein the openings (9) form a joint bearing (10) for the tilting joint (7).

Abstract: The adjustable stand (1) includes a tubular arm (2); an arm joint (5) by which the tubular arm (2) is pivotally connected to a connection part (22); a spindle (6) in the tubular arm (2) that receives a compression spring (3) with a given pre-tensioning provided by a first spring stop (7) in the form of a washer and by a second spring stop (8). The spindle (6) has an axial extension (9) pivotally connected with the connection part (22) by means of a lever (11) The tubular arm (2) is provided with two opposing indentations (13) having a distance (X) from one another, the washer forming the first spring stop (7) has two opposing first sides (14) closer to each other than the distance (X) between indentations (13) and two opposing second sides (15) arranged rotated 90.degree. to the first sides and further from each other than the distance (X) between indentations (13), so that the washer may pass by the indentations (13) during assembly and rotate 90.degree. to take a bayonet locking position.

Abstract: The present invention includes an overhung turbine wheel which is provided with at least one ring of turbine blades and is connected with a shaft. In order to control the thermodynamically required circumferential speeds necessary to achieve maximum efficiency, the turbine wheel is designed as a closed disk which is narrow in the axial direction. The turbine wheel is integral with the turbine blades and furthermore is connected to the shaft through planar connecting surfaces having interfitting teeth. The turbine wheel has a relatively low mass, and the interfitting teeth allow a simple and optimal centering connection. Radial-flow turbines of this kind are standardized in model series, the turbine wheels and shafts in each case being provided with similar interfitting teeth to allow mutual combinations as desired.
