Patent EP-0478535-A2 (EP)
Inventor: ICKINGER GEORG DIPL-ING-DR TEC
IPC: D21F3/02

Abstract: The invention relates to a procedure for manufacturing an object coated with polymer, in particular with elastomer, on a curved and/or flat surface, for example a roller, pressure cushion, pressing shoe, heating/cooling mat, lubricated bearing segment. The invention is principally characterised in that the polymer, in particular elastomer, is produced in a localised manner without adhesion to the coated and/or uncoated object surface and is expediently lifted off there from the coated and/or uncoated object surface. The invention also comprises an object coated with a layer of polymer, in particular a layer of elastomer, on a curved and/or flat surface, for example a roller, pressure cushion. The object according to the invention is principally characterised in that on the coated and/or uncoated object surface, for example the circumferential surface of a roller, pressure cushion, there is arranged at least one localised adhesion inhibitor or preventer or reducer, the region of which may have a feed line or discharge line for gaseous or liquid medium, in particular air. According to the pressure difference between inlet and outlet, the hollow space produced will vary in size and this in turn results in a corresponding throughflow of medium, or results in a different outlet rate, if the hollow spaces are connected to the surface by small openings, which is used advantageously in the case of lubricated bearings or in the case of pressing shoes or coating and moistening rollers. Even in the case of heating and cooling plates or rollers, the proximity of the medium to the surface and the ability to regulate the throughflow rate lead to applications in paper, plastics, pulp, printing and textile machine engineering. According to the pressure difference, corresponding pressure and force of reaction can be exerted in at least one region of the interconnected hollow spaces and, in the case of counter-pressure, by elements in contact with the surface, such as for example a printing plate, counter-roller, screen cloth. This effect is advantageous in the case of pressure cushions, pressing plates, wide nip rollers. The invention is based on the object of permitting hollow-space shaping, or profile shaping, or varied heat transfer contact by the elevations on the coating surface in a simple and inexpensive way by simple insertion of strips or preformed inserts or films or the like or else a coating or layer of lacquer or the like on the coated and/or uncoated object surface in an easily reproducible and also multi-layered way. <IMAGE>

Abstract: The headlamp has a reflector (10), which is subdivided into four segments with different reflective surfaces. Fitted in the reflector (10) is an incandescent lamp (14) with an axial spiral-wound filament (16), which extends approximately along the optical axis (18) of the reflector (10). The reflector (10) is bounded at the top and bottom by planar surfaces (30, 32). The lower bounding surface (32) is provided with a reflective coating and is inclined downwards with respect to the optical axis (18) in the direction of the light by an angle  alpha  of about 5 DEG  to 7 DEG . Light emitted by the spiral-wound filament (16) and reflected by the lower segments of the reflector (10) onto the lower bounding surface (32) is reflected by this arrangement of the lower bounding surface (32) approximately parallel or, in the direction of the light, inclined slightly downwards with respect to the optical axis. The light reflected from the lower bounding surface (32) can consequently be used for producing the actual light distribution of the reflector (10). <IMAGE>

Abstract: The invention relates to a reflector lamp having a reflector which partially surrounds a light source, is surrounded by an upper, opaque, hood-shaped housing part, and arranged by means of a holding device in a transparent opaque, lower housing part which is covered by the upper housing part and whose lower end is detachably connected to a dish-shaped top piece. The aim is to improve the manipulability of such a reflector lamp, in particular to be able to exchange the light source in a simpler fashion. This is achieved according to the invention when the holding device (5) is fastened to the top piece (7), extends away from the latter parallel to the vertical longitudinal axis (14) approximately as far as the level of the upper rim (15) of the lower housing part (6), and has on its upper, free end a pivotable support plate (16) which accommodates the reflector (2, 3) and the light source. <IMAGE>

Abstract: An image-transfer and sheet-separating apparatus (13) transfers an image toner-developed from a positive latent image and retained on a photoconductor drum (9) onto a copy sheet, and subsequently separates the sheet from the photoconductor drum (9). A sheet peel-separating AC voltage superimposed on an image-transferring DC bias voltage is applied to a transfer roller (31) which presses on the photoconductor drum (9). A post image-transfer charge-stripping element (35) removes charge from the copy sheet and is disposed in a portion of the sheet-transport stream forward of a nipping position at which the transfer roller (31) presses against the photoconductor drum (9). Thus, charges remaining on the copy sheet are discharged, ensuring high efficiency in image transfer and accordingly reducing the incidence of failure in the separation of the copy sheet from the photoconductor drum (9).

Abstract: HDMAC TV signals can be transmitted in a compatible way over existing D2MAC channels. In HDMAC the pixels are subsampled in different order within each two- or four-field sequence. This subsampling in the current HDMAC encoding algorithm produces a 25Hz twitter along vertical coloured edges in standard MAC receivers. In even fields a shift of half a 20.25MHz clock period is carried out in the multiplexer to arrange even field luminance pixels in their proper horizontal spatial position. The same shift is applied to the even field chrominance pixels, which is in fact the opposite of what should be done. Therefore, the arrangement of the luminance and chrominance samples prior to the current HDMAC multiplexer and subsequent to the HDMAC demultiplexer in the receiver, respectively, is modified. The horizontal position of the chrominance pixels within the compatible picture is matched to the position of the respective luminance samples.

Abstract: An operating system combines preemptive scheduling with cooperative or non-preemptive scheduling. In particular, tasks are divided into groups of interdependent tasks. Each group includes tasks that should not be run asynchronously relative to each other. The scheduler in the operating system provides each group with a time slot of processor time. The tasks within the group are cooperatively scheduled to exploit the time slot assigned to the group. Dependencies between modules and tasks are maintained to assure that no difficulties arise amongst preemptively scheduled groups.

Abstract: Method for speech signal synthesis by means of time concatenation of waveforms representing elementary units of speech signal, in which: at least the waveforms associated to voiced sounds are subdivided into a plurality of intervals, corresponding to the responses of the vocal duct to a series of excitation impulses of the vocal cords, synchronous with the fundamental frequency of the signal; each interval is subjected to a weighting; the signals resulting from the weighting are replaced with a replica thereof shifted in time by an amount that depends on a prosodic information; and the synthesis is carried out by overlapping and adding the shifted signals. In each interval of original signal to be reproduced in synthesis, an unchanging part is identified, which contains the fundamental information and which is reproduced unaltered in the synthesized signal, and the operations of weighting, overlapping and adding involve only the remaining part of the interval.
