Abstract: In the case of a flexible sanding back-plate, the clamping shank (1) is connected by means of a flexible coupling to a turntable (7), the deflection of which can be set by a sleeve (12), which can be adjusted axially from the clamping side. To achieve considerable deflectability of the turntable and a construction from simple individual parts which can be merely screwed together, the coupling is designed as a flexible disc (2), the outer edge region of which is clamped between an elevated annular bead (6) of the turntable (7) and a domed flange (9, 20, 40) having a conical coupling face (15, 42), to which a corresponding counter-coupling face (14, 43) is assigned. <IMAGE>

Abstract: The flowmeter has a measuring element, for example a vane wheel, which is movable as a function of the flow velocity of the electrically conductive liquid medium to be detected and which is connected to a voltaic speed sensor, whose electric pulses can be fed to an electrical or electronic counter. The voltaic speed sensor is formed by elements which are provided parallel to the axis of rotation of the measuring element and are all arranged approximately on the same radius from the axis of rotation and connected to the measuring element. Outside and inside the circle of motion of the elements, the electrodes are located, via which the signals serving to count the revolutions can be tapped. The elements and electrodes are surrounded by the liquid medium. According to a further development, the elements are designed as a tube part which, in its shell surface, has slots which can be scanned by the electrodes from inside and outside the tube part. <IMAGE>

Abstract: This invention concerns the production of textured surfaces, and in particular to compositions for producing such surfaces. The compositions include a radiation-curable component, an adhesion promoter for promoting adhesion to a substrate, and a texture-modifying amount of microspheres substantially homogeneously dispersed therein. The microspheres can be of glass, ceramic or polymeric materials, and they can be solid or hollow. Various adhesion promoters can be used, and in general the choice will depend upon the curable system used. For example, certain polymers, monomers or unreactive volatile solvents can be used as adhesion promoters with free-radical curable compositions. Texturing can be effected on the surface of a variety of materials, for example on plastics or cellulosic substrates.

Abstract: The invention relates to a rotary, Perkins tube heat exchanger for processing hot contaminated gas flows emanating from appliances such as laundry driers, grain driers and the like. The case (10) of the heat exchanger is located relative to the rotor (12) so as to lie in the gas flow boundary layer established by the latter. The case (10) is provided with a boundary layer purge port (56) in the hot gas chamber (28). An airfoil (60) extends inwardly from the case into the gas flow boundary layer. It causes increased local turbulance in the boundary layer gas. It also diverts a predeter­mined proportion of the boundary layer gas and its burden of contamination products out through the purge port (56). The boundary layer airflow cleans both the interior of the case (10) and the rotor (12), even though the rotor is characterized by the pre­sence of a multiplicity of small openings. The device thus is rendered self-cleaning and may be operated for extended periods of time without buildup of contaminants within the heat exchanger case.

Abstract: A conformal organic layer is used to define spacers on the sidewalls of an organic mandrel. The organic layer (e.g., parylene) can be deposited at low temperatures, and as such are compatible with temperature-sensitive mandrel materials that reflow at high deposition temperatures. The conformal organic material can be dry etched as the same rate as the organic mandrels, while being resistant to wet strip solvents that remove the organic mandrels. This series of etch characteristics make the organic mandrel-organic spacer combination compatible with a host of masking applications.

Abstract: Fibre webs are consolidated and embossed using pairs of rotating calender rolls between which the fibre web passes. The calender rolls have been provided with raised discrete areas which form a surface pattern and determine the pattern which is embossed on the fibre web. To emboss different patterns, depending on the desired constitution and stiffness of the fibre web, different calender rolls are available, but it is very inconvenient to interchange the calender rolls. To avoid this disadvantage, the calender rolls of the novel apparatus are each driven at a synchronous speed and it is made possible to alter the speed of one of the rolls for a short time, so that the surface patterns of the two calender rolls become displaced relative to one another. This creates different degrees of overlap between mutually opposite pairs of raised areas, so that it is possible to set different embossing patterns in the course of continuous operation without it being necessary to replace the calender rolls. <IMAGE>
