Title: Presse zum kontinuierlichen Herstellen von Span- und Faserplatten oder dergleichen
Inventor: GERSBECK ROLF
IPC: B27N3/26
Filed: 1988-10-31
Abstract: Es wird eine Presse zum kontinuierlichen Herstellen von dünnen Span- und Faserplatten (22) aufgezeigt, bestehend aus einer zentralen, in Ständern (1) gelagerten Preßtrommel (2) und mehreren Umlenk-(9) oder Andrückwalzen (3,4,5) sowie einem endlosen, um die Preßtrommel und die Andrückwalzen herumgeführten, unter Zugspannung stehenden Stahlband (6), wobei die mit einem Bindemittel vermischte Span- oder Faserschicht zwischen dem endlosen Stahlband und der beheizten, rotierenden Preßtrommel einem Flächendruck und in den Spalten zwischen der Preßtrommel und den Andrückwalzen einem Liniendruck unterworfen wird. Dadurch, daß die Achse der Preßtrommel gegenüber den Achsen der Andrück- und Umlenkwalzen radial verstellbar ausgebildet ist, wird erreicht, daß die Presse ohne Schäden an der Preßtrommel und dem endlosen Stahlband sowie den Andrückwalzen im Leerzustand angefahren werden kann, auch wenn damit sehr dünne Bahnen hergestellt werden.

Abstract: This invention provides an erasable optical disk, on which information is recorded and reproduced repeatedly through the irradiation of laser beams, and an optical information recording/reproduction apparatus which records and reproduces information on the erasable optical disk. In erasing and then recording information on the erasable optical disk by using an erasing laser beam and a recording/reproduction laser beam, respectively, the tracking of both laser beams on the same track is detected so as to prevent erroneous erasing. The apparatus uses the optical disk having a mark signal (M1, M2) disposed between a sector identifier (ID) and a data field (DF), which mark signal (M1, M2) is capable of determining the presence of the erasing laser beam on an adjacent track on the erasable optical disk, and the apparatus reproduces and detects the mark signal (M1, M2) by using the erasing laser beam. The apparatus discriminates the position of the erasing laser beam depending on whether the mark signal has been detected or not, thereby preventing erroneous erasing of data on the adjacent track and simultaneously assuring the presence of the erasing laser beam on the same track along with the recording/reproduc­tion laser beam.

Abstract: A machine for processing mail to separate the items whose destination address is typed or printed from those which are in manuscript. The machine reads the information on the items and distinguishes the destination address from a sender's address. The destination address is then examined to recognise typed or manuscript forms according to the dispersion of the height of letters, the spacing between letters or lines, etc. The machine calculates the dispersion of only the bottom or one or two lines of the address because this is where the most useful information is present.

Abstract: The precision operational amplifier of the invention has at least two stages, a first input differential stage (10, 11) and a second high gain stage (20) having its input coupled to the output of the first stage. A digital control circuit (40) coupled to the output of the second stage is used to supply a correction signal to the first stage, the correction signal being calculated to compensate for the offset voltage of the first stage (10, 11). A digital representation of the correction signal is stored so that it may continuously be applied to the first stage, whereby the offset voltage of the first stage is sub­stantially reduced and such reduction can be maintained for long periods of times. In a preferred embodiment, the digital circuit (40) supplies a second independent correction signal to the second stage (20). That signal is also stored so that it may con­tinuously be applied to the second stage (20), whereby the offset voltage of the second stage (20) is substantially reduced and that reduction too can be maintained for long periods of time. The circuit of the invention may be contained in a single chip, monolithic integrated circuit.

Abstract: The breaking tools (5) are designed as rocker-shaped cutters with cutting edges (7, 8). The cutters (5) are mounted on a frame (3) in such a way as to be pivotable about a horizontal axis (14). The breaking tools (5) are actuated by one piston-cylinder unit (6) each which is almost perpendicular and is linked to the box-shaped frame (3). Consequently, the device can be of narrow construction. Furthermore, the rocker-shaped design of the breaking tools (5), on account of different lever arms (19, 20), permits an increase in force without it being necessary to exchange the piston-cylinder units (6). Furthermore, the device is adapted to concrete piles (2) of different thickness merely by exchanging the breaking tools (5), the cutting-edge dimensions (7, 8) of which are adapted to the respective distances between the reinforcement rods. …<IMAGE>…

Abstract: A clock signal supplying device is provided with an automatic phase regulating function for preventing errors in the phase regulation due to noises. In the device is provided a refer­ence signal serving as a phase reference. Transmission lines (30) for clock signals and a transmission line (31) for the reference signal are disposed from a clock signal supplying source (10) to devices (20), which are destinations of dis­tribution of clock signals. The transmission line for the reference signal is adjusted in advance so as to produce no skew. In the device (20), which is the destination of distri­bution of the clock signal, there is disposed a variable delay circuit (51) for regulation of the phase of the clock signal and a phase comparing circuit (52) for comparing the output of the variable delay circuit (51) with the phase of the refer­ence signal to output the result of the comparison. The amount of delay by the variable delay circuit (51) is controlled, responding to the output of the phase comparing circuit (52). Further, a noise filter is provided, which detects phase re­gulation errors to effect correct phase regulation. The phase regulation is effected while avoiding a period of time, where noises are apt to be produced.

Abstract: In the calibration of a vector demodulator, a statistical approach is used for the analysis and correction of received data. The magnitude of each vector, defined by an (I,Q) pair in a received data signal, is examined. If each measured magnitude has a predetermined value, calibration is not necessary. However, if the vector magnitudes differ from this value, a number of samples of the data signal are used to define a linearly transformed circle. The transformation parameters of this model are then calculated, for example using a least squares analysis. These parameters are related to the system errors to be corrected, and hence can be used to determine calibration factors which are employed to adjust the received information and produce actual data values.

Abstract: A pneumatic axially oscillated, frictionally rotated roller (30) is disclosed and may be used in the ink (12) or dampening (13) systems of a printing press. The roller (30) features an internal air piston-cylinder construction that causes the axial motion but permits the roller (30) to freely rotate. Further, several air cylinders can be stacked on each side of the roller (30) to permit even a small diameter roller to be pneumatically oscillated. The roller (30), when used as an ink form roller (18), may be operated to oscillate in synchronization with an adjacent oscillating, vibrating roller (120) to continually diagonally redistribute the ink so as to eliminate or minimize "ghosting". The foregoing is accomplished by controlling the oscillation of the form roller (18) to move axially in a direction opposite of that of the vibrating roller (120). The lengths of the strokes of the two rollers (30, 120) may differ or be the same. The length of axial movement or stroke of the form roller (18) can be varied, while maintaining synchronization by varying the speed of the axial motion, a slower speed yielding a shorter stroke and a higher speed yielding a longer stroke for a given half cycle.
