Inventor: MOEHLENHOFF ANDREAS
IPC: F24D3/14
Filed: 1993-02-04
Abstract: A convector comprising an elongated, trough-shaped channel (5) of approximately rectangular cross-section is specified. In the region of a longitudinally running side wall of the channel (5), a heating element (8) extending virtually over the entire length thereof is mounted in such a way that a free space is present both with respect to the bottom (6) of the channel (5) and with respect to the other side wall thereof. At one end face of the channel (5) a blower is mounted in the same. In addition, a duct (13), constructed as a hollow profiled body, which is separated from the heating element (8) and runs parallel to the same is arranged in the channel (5). The duct (13) is mounted, while maintaining the free space (10) with respect to the bottom (6) of the channel (5), laterally beside the heating element (8) in such a way that there remains with respect to that side wall of the channel (5) remote from the heating element (8) a free space (9) which is connected to the free space (10) existing with respect to the bottom (6) of the channel (5). An opening (18) consisting of at least one slot is disposed on that side of the duct (13) remote from the heating element (8), in the wall of said duct, in such a way that air blown into the duct (13) by the blower emerges from the duct (13) in the direction of the bottom (6) of the channel (5) and entrains air from outside the channel. <IMAGE>

Inventor: GLATZ DIETMAR
IPC: A47L9/06
Filed: 1993-02-16
Abstract: The vacuum cleaner nozzle of the invention has a nozzle body (1) with a suction-pipe connection and a baseplate (2) which closes off the nozzle body at the bottom, the baseplate having at least one flow channel (3, 4) which is open at the bottom and leads into a central suction channel (5) connected to the suction-pipe connection, and sealing or closing-off elements which surround the flow channel at least in certain regions. The nozzle body and the baseplate are designed here as an integral carrier, into which the flow channel or the flow channels and the suction channel are directly moulded. The sealing or closing-off elements in the form of bristle strips (17, 18) and/or sealing lips (13, 14) are directly moulded and/or pressed, injected or adhesively bonded into the baseplate. By virtue of this design, the number of components of the vacuum cleaner nozzle is reduced substantially, thereby resulting in a significant simplification with regard to production and assembly. <IMAGE>

Title: Process and apparatus for renewing a buried pipeline consisting of an asbestos-containing material
Inventor: GEISS DIETER
IPC: F16L55/28
Filed: 1993-03-03
Abstract: A pig is moved through the pipeline, which pig is provided with a cutting device (5) in order to produce defined predetermined breaking points in the pipeline.

Title: Radiation measuring device for luminescence and fluorescence measurement
IPC: G01N21/01
Filed: 1993-08-18
Abstract: Until now, luminescence and fluorescence measurements have been carried out by means of two corresponding measuring devices. The expenditure in terms of equipment for users of both methods, in particular in the case of rapid analyses on site, is very high. Both measuring methods are intended to be able to be carried out using the new measuring device. A mechanical device (2) having optical (3) and electrical interface (4) is mounted on the end of the radiation measuring device (1), which contains the essential subassemblies such as power supply, detector, indicator, microcontroller, operating keyboard and data interface. Depending on the measurement task, corresponding measuring heads (5, 6) can be coupled to this device (2). This radiation measuring device enables the carrying out of luminescence and fluorescence measurements by simply exchanging the measuring head. Since practically any desired measuring heads, which only need to satisfy the requirement of the optical/electrical interface, can be coupled to this radiation measuring device, the universal use of this device in radiation measuring technology is possible. In particular in the case of portable or hand-held measuring devices, small volumes result, accompanied by the highest flexibility. <IMAGE>

Title: Grinding machine with oscillating spindle
Inventor: HASHII TOSHIMITSU
IPC: B24B27/02
Filed: 1994-03-11
Abstract: The invention relates to a grinding machine with oscillating spindle, having a spindle arranged rotatably in a housing. A projecting end of the spindle is designed to receive a grinding drum. An upper cam disc is rigidly connected to the spindle, and a lower cam disc inside the housing is rotatably connected to the spindle. The upper and lower cam disc have opposite annular cam faces, the contours of which, shaped alternately sinusoidally, exhibiting respective diametrically opposite elevations and depressions. Upper and lower cam discs possess toothed rings which are connected via separate driving belts to a common driving pulley driven by an electric motor. The number of teeth of the toothed rings of the upper and lower cam disc are different, so that upper and lower cam disc rotate relative to one another. The annular cam faces cause the upper cam disc and the spindle to oscillate in the vertical direction owing to the relative movement of upper and lower cam disc.
