Abstract: A receiving arrangement is suggested for a hard roof, particularly for a hardtop of a motor vehicle, which is arranged on a movable stand. The movable stand has a carrying device formed of struts which has at least four bearing receiving devices for the hardtop. These bearing receiving devices are arranged to correspond to locks and push-in tongues of the hardtop. The carrying device, together with the bearing receiving devices, is constructed to be separable from the stand and forms a separate, locally fastenable carrying device. Furthermore, it is provided that the stand can be adjusted into a horizontal working position, for which a supporting tube is used which can be supported on the basic stand.

Abstract: A method for determining optimum controller parameters for a digital rotational speed control is described, in which various test signals are applied to a speed control loop and the resulting speed characteristic is determined. The speed characteristic is subsequently weighted with respect to rise time and transient response for various controller parameters, and the most favorable controller parameters are subsequently set in the controller of the control loop. The integral-action time of the control loop is used as a criterion in performing the weighting operation.

Abstract: An operating element is provided for a proximity regulating device for vehicles with an actuating lever. The operating element actuating lever has a rotatably mounted head that can assume a plurality of radial switch positions. If the head is in its initial switch position, the proximity regulating device sets an initial distance from a leading vehicle. As the result of the rotary movement from this initial switch position, one or more additional radial switch positions can be set for a near distance in which the proximity regulating device sets a set distance from a leading vehicle that is shorter than the initial distance. Finally, one or more radial switch positions are provided in which the proximity regulating device sets a far distance that is greater than the initial distance.

Abstract: A wheel for a motor vehicle has a rim spider provided with air openings and is connected with a rim well. The wheel comprises at least two shell parts which are constructed as a rim well and a rim spider and assembled and which each have an interior wall and an exterior wall. In the area of the air openings, these are connected with one another and each form hollow spokes between one another which, on respective end sides, lead into concentric annuli of the wheel.

Abstract: A nozzle array for levitational guidance of web material. The nozzle array includes a sequence of nozzle areas in the transport direction of the web which are peripherally encompassed at least in part by fanned jets and their width varies in the direction transversely to the web transport direction. The nozzle areas may be equipped with orifice nozzles. Located between the nozzle areas are return flow zones which may be configured as return flow passageways open towards the web, whereby their cross-section is flared in the direction of the edges of the nozzle array. The nozzle areas may be v-shaped relative to their longitudinal axis oriented in the transport direction of the web. Clusters of nozzle areas may be arranged juxtaposed as viewed in the web transport direction.

Abstract: A bioactive surface layer with 0.01 &mgr;m to 5 mm thickness is suitable for a metallic bone implant. The surface layer has the following composition: (A) calcium compounds (CaX) consisting of crystalline calcium phosphate (CaP), calcium apatites (CaAp) and/or calcium carbonate (CaCO3), in a proportion expressed by the following equation: 100% (CaX)=&Sgr;[x % (CaP)+y % (CaCO3)], in which x+y+z=100, 0≦x≦100; 0≦y≦100; 0≦z≦100, and in the form of particles 20 nm to 4 mm; and (B) amorphous or crystalline metal oxide (MeO). The ratio between CAX and MeO in the surface layer can be preferably varied as a result of the specific coating process. The thickness of the surface layer lies between 0.01 &mgr;m and 5 mm and the CaX particles are 20 nm to 4 mm large.

Abstract: A tool for the machining of workpiece surfaces, especially of drilled-hole surfaces, has at least two parts which are displaceable relative to each other. The tool for the machining of the workpiece surfaces is rotatable and includes at least one control member (19) which is displaceable relative to the tool (1) substantially perpendicularly to the axis of rotation (9) of the tool. The control member, preferably from a preset threshold speed of rotation, effects a movement of one part (5) relative to the other (3).

Abstract: The invention relates to a device for cooling extruded profiles (2) comprising slotted air nozzles (6U, 6O) arranged above and below the extruded profile moving on an exit runway (1) and oriented transversely to the direction of movement of the profile, and water impingement nozzles (12) for impinging the extruded profile with water, wherein the water impingement nozzles are arranged separately from the slotted air nozzles (6U, 6O) in tubes (12) oriented in the direction of movement of the profile such that the impingement portions of the individual water impingement nozzles (12) supplement to achieve a homogenous impingement of the extruded profile (2).

Abstract: A circuit arrangement allows a converter to be operated with supply voltages oscillating within broad limits. The intermediate circuit voltage of the converter is controlled to avoid unacceptably high currents, so that the intermediate circuit voltage is always higher than the peak value of the rectified supply voltage. For at least this purpose, the peak value of the rectified supply voltage is determined and compared to that of the intermediate circuit voltage. If the intermediate circuit voltage is less than the peak value of the rectified supply voltage, the intermediate circuit voltage is increased to exceed the originally set setpoint value. This prevents free-wheeling diodes from becoming conductive at undesirable times and causing excessive currents.
