Abstract: A chuck for rotary tools with a cylindrical chucking shank encloses such shank with a basic body. A radial through-hole in basic body serves to receive a clamping screw which applies pressure to a clamping member which is seated inside a through-hole between the clamping screw and chucking shank. A clamping member is provided with a radial projection and the through-hole with a cross-sectional narrowing along its inner end. In between the radial projection and the narrowing is an elastically compressible spring element which, due to its return force, lifts the clamping element away from the chucking shank and pushes it back into the through-hole when it is not under tension from the clamping screw.

Abstract: A clamping fitting to attach glass panes whereby the clamp screw's screw head and screw shank are conceived as individual components, so that the screw head is vertically displaceable in four degrees of freedom with regard to the screw shank's axis and fixable at a screw shank's holding flange in order to achieve tolerance compensation in the glass pane's plane between the wall mounting and the bore hole in the glass pane. Between a support flange sitting close to a carrier structure and a bore hole in the glass pane, a locating flange sitting close to the glass pane is provided for, which locating flange's distance is variable with regard to the support flange. The distance adjustment is realized by penetrating through the bore hole in the glass pane.

Abstract: Arrangement of an electrical heating element as a cooking zone, having as a carrier a ceramic of very high thermal conductivity, in a cutout of a cooking surface comprising glass-ceramic, glass, ceramic, metal or plastic. The ceramic carrier of the heating element has, above the plane of the cooking surface, a region, by means of which region the carrier engages over the cutout onto the top of the cooking surface and by means of which region the carrier rests on the cooking surface by a gasket. The ceramic carrier forms, in the plane of the cooking surface, a further region, by which further region the carrier is positioned in the cutout at a distance from the end faces of the latter, and, below the plane of the cooking surface, a region having shaped-out portions serves as a bearing for an element which element, with the aid of the cooking surface as an abutment, fixes the heating element in the cutout of the cooking surface.
Abstract: A movable wall comprises individual suspended door and/or wall elements. The individual elements are automatically locked both to one another and in the floor. For this purpose, in a base profile which is fastened to the underside of the elements, there is structure which effects an automatic locking of the elements to one another and in the floor, when two elements come together.
Abstract: A joist element for fastening a flat, plate-shaped structural element to a pitched roof. In particular for fastening a solar energy collection module, whereby the joist element, laid in the ridge-eaves direction, can be fastened to the roof substructure.
Abstract: A runner or guide rail for a running mechanism for suspension-mounted dividing walls or partitions. The runner or guide rail is configured as a box-shaped hollow section comprising two U-shaped sections with their U-limbs pointing towards each other. A part of the runner or guide rail is detachable in order to create an inspection opening. This detachable part of the runner rail comprises a web of a U-section and a corresponding U-limb, said U-limb delimiting the guiding slot which a supporting member fits through.
Abstract: A double-seat valve with an upper valve stem and a lower valve stem which, on the end, each have valve sealing bodies, each of which valve sealing bodies has a seal which is located on the balance diameter. One of the valve sealing bodies also has a center seal which is used to seal a leakage space when the valve stems are in the open position. The center seal also lies on the balance diameter. The other valve sealing body has a sealing collar, against which sealing collar the center seal is in contact when the valve stems are in the open position, so that even in this case, a sealing of the leakage space is guaranteed.

Abstract: An ink fountain with an ink-duct roller in the inking mechanism of printing presses, with a device for filling printing ink into the ink fountain, is described. The device for filling ink is mounted on a sled so that it can be moved back and forth in the longitudinal direction of the ink fountain. A sensor is fastened to the sled, and when the ink level is too low, the sensor controls the ink feed. Thereby, a precise regulation of the amount of ink added can be achieved by means of a downstream dosing device.
Abstract: A measuring technique and method are provided to simultaneously determine the molecular density of several molecular species and the temperature within a closed process room in a melting or combustion process. In such processes in the industry, e.g. in metallurgic process industry, it is important to determine the temperature and the contents within the gas or flame without physically connect to or disturb the process. This has shown to raise large problems especially at high temperatures. The radio signal over a frequency band is measured on the outside of the process room through a window in the mantel covering as a function of frequency and registered on a computer as a radio spectrum. The system is calibrated by using a known signal transmitted through the process room. The spectral lines are identified by their frequency from a database. The temperature is determined from several lines of the same molecular specie and the molecular densities are determined from the intensities of the lines.
Abstract: The movable partition system has a plurality of movable partition elements placed on a horizontal rail. Each of at least two of the movable partition elements has its own electric motor. Each electric motor has a current collector connected to it which passes along at least two conductor rails which are part of the electrical circuit when the electric motor is moved. These rails are connected via lines to a control unit which controls the power supply and the operation. One conductor rail is connected with a single line. On the other hand, at least one other conductor rail has a plurality of lines which lead to electrical connections or taps which are isolated from one another by insulators. This isolation permits the control unit to control the individual flow of current to each separate tap. This makes it possible to individually control and position the individual movable partition elements.
