Abstract: A method for measuring a program-controlled machine tool using a measuring sphere. According to this method the measuring sphere having known dimensions is positioned on a machine part. A sensing element installed in the machine is moved to a selected initial position in which it is located approximately 10 mm above the vertex section of the sphere. Then the sensing element is repeatedly moved until it contacts various points on the surface of the sphere, and the coordinate values of those points of contact are input into the controller. Thereafter the spatial position of the center of the sphere is calculated and compared with target values stored in the controller.

Abstract: A water purification system includes an activated carbon filter and a reverse-osmosis (RO) filter. The activated carbon filter is typically formed with a central aperture that receives an upper portion of a central tube. The RO filter, which is positioned downstream from the carbon filter, may be formed around a perforated section of the central tube. The system further includes a head that is structured to receive a sump that contains the carbon and RO filters, as well as the central tube. An inlet formed in the head enables unpurified feed water to flow into the carbon filter. A first channel, which is defined by an annular surface formed in the carbon filter and an outer surface of the central tube, enables water to flow into the RO filter. A channel within the central tube enables water to flow from the RO filter, through the perforated sections of the central tube, and into an outlet formed within the head.

Abstract: A device to measure a fluid dynamic bearing system, particularly the inside diameter of the bearing bore of a bearing sleeve or the outside diameter of a shaft using a sensor element. A capacity acting sensor element is used to determine, for example, the inside diameter of the bearing bore, the sensor element being designed as part of the surface of a shaft prepared for measurement purposes. To determine the outside diameter of the shaft, the sensor element is correspondingly designed as part of the surface of the bearing bore of a bearing sleeve prepared for measurement purposes. Means of introducing a measuring fluid, preferably compressed air, into the bearing gap remaining between the bearing sleeve and the shaft are provided so that during the measurement process the shaft is automatically aligned and centered within the bearing bore.

A handling device is vertically and horizontally shiftable by means of a motor located adjacent to the shelf. At least one gripper arrangement is provided for extracting predetermined tools from the shelf and for transferring them to a tool changer. At least one shelf has compartments with notches serving as tool accommodations on the front and back side. The notches on the front side are located in the access range of the handling device and the notches on the back side are accessible for retooling. The shelf is formed so as to be rotatable about an axis for a change of sides.

Abstract: A turbine wheel for driving rapidly rotating tools, in the form of a circular disk or ring, configured for mounting so as to be rotatable about an axis. Disposed thereon in circular formation are turbine blades having axially parallel front and back faces curved in the radial direction. The front face has a lesser radius of curvature (R3, R4), at least in portions, than the back face. This feature allows the turbine wheel to fit into the conventional turbine housings without relatively major redesign and with, at most, slight modifications. The turbine wheel can achieve higher torque than previous turbine wheels at the required high rotational speeds. Thus, a greater quantity of material can be applied to the spraying dome or a spraying disk without a detrimental braking. Surfaces to be sprayed can be provided with a uniform coat of material in shorter time.
