摘要： Sheet formation system and method for reducing wavy edges in a fourdrinier machine. The system includes a headbox having a nozzle bring adapted to produce a pulp suspension jet across a width of the machine, at least one rotating screen positioned to receive the pulp suspension jet, and at least two deckle plates adjacent to the screen. The deckle plates may be adjustably positionable such that a distance between the deckle plates and a centerline of the screen is adjustable in a machine direction over a substantial portion of a length of the side shields. The method includes directing a pulp suspension jet onto the rotating shield between the deckle plates to form a web sheet, moving the web sheet in a machine direction, and adjusting a distance between the deckle plates as the web sheet is moved in the machine direction. The method also includes positioning the mechanical deckle plates having a flat surface being adapted to face the pulp suspension in the pulp suspension application area to form edges of the sheet being formed and bending the flat surface of the mechanical deckle plates as the formed sheet travels in a machine direction.

摘要： A colored original to be reproduced is scanned point-by-point in each of the three primary colors. The resulting imaging signals are processed to generate a luminance signal and a pair of chrominance signals. The luminance signal is branched into a high-pass filter channel and a low-pass filter channel. The high-pass portion of the luminance signal is amplified in accordance with a sublinear characteristic function which causes signals of small amplitude to be amplified to a greater degree than signals of large amplitude. The low-pass portion of the luminance signal is modified per a non-linear characteristic gradation function. The thus-modified high-pass and low-pass portions of the luminance signal are added to yield an enhanced luminance signal. The enhanced luminance signal is divided by the original luminance signal and each of the chrominance signals is multiplied by the resulting quotient. This automatially compensates for the changes in color saturation which accompany changes in brightness. After the multiplication, the chrominance signals are amplified in accordance with a sublinear characteristic function which causes signals of small amplitude to be amplified to a greater degree than signals of large amplitude. This characteristic function further has a form such that no additional ampification takes place beyond a predetermined threshold limit.

摘要： The dynamic random access memory for use in a video circuit scanning video images according to the interlaced scanning method and reproducing the images on monitors of different resolutions is described. The RAM memory is composed of as many RAM segments as there are graduations of picture elements available, each segment including a plurality of RAM chips determined by the minimum read/write cycle time and by the scanning cycle time. To speed up the addressing during the switchover from the low-resolution to a high-resolution reception, the memory is organized into two halves, for storing respectively signals pertaining to odd-numbered and even-numbered picture lines. In each half, the vertical columns are subdivided into groups of lines pertaining to a single video data word. The adjoining pairs of columns store the signals pertaining to corresponding pairs of consecutive video lines which, in each pair, are arranged one below the other. In this manner the access time in the memory during the low-resolution is made faster.

摘要： A galvanometric tilting-mirror scanning system shifts an image of an original projected onto a photodiode row in a direction transverse to such row. The tilting-mirror mechanism is provided with an oil-filled damping chamber, heated and maintained at stabilized temperature. The control voltage driving the tilting-mirror system includes a sawtooth component whose lower-slope flanks determine the mirror's scanning sweep; a negative pulse which effects mirror tiltback or flyback; a positive pulse which brakes the tiltback and accelerates the mirror back up to its forwards-direction scanning-sweep speed; and finally a corrective component. The corrective component has the form of a pulse which increases the slope of the sawtooth component's lower-slope flanks during a time interval extending beyond the system's vertical blanking allotment, to compensate the non-linearity in the motion of the mirror which would exist during its forwards-direction scanning-sweep interval in the absence of the corrective component.

摘要： An air outlet for the admission of conditioned air to rooms and other inhabited spaces includes an air box with an air outlet slot. The air outlet slot is longitudinally subdivided to form individual ducts each of which contains an independently adjustable air guide vane. Internally, the outlet slot may be variably obturated by three superimposed control slides, each of which has periodically occurring covering surfaces, the width of which corresponds to the width of an air outlet duct. The covering surfaces on each control slide are disposed at a distance corresponding to four duct widths. The air box contains thermostatically controlled actuators which are coupled to the control slides in such a way as to permit their relative longitudinal, i.e., axial, displacement when a first control slide is moved between positions corresponding, respectively, the second and/or third control slides are partially carried along so as to define configurations resulting in a variation of the volumetric air flow but maintaining the speed of the emerging air constant.

摘要： An original is sampled line-by-line at a predetermined number of points along each line and sampling signals indicative of the density of the original in each of three colors are furnished while electrographic paper or film is transported past a first, second and third recording station. At each recording station a line of electrodes having a length exceeding the width of the copy to be made and exceeding in number the number of sampling points of the original along each line extends in a direction perpendicular to the direction of transport of the paper. A mark on the paper is sensed at each station and the deviation of the position of the mark from a desired position in the line direction determines which electrode will be used to start the recording of the line. In the direction of transport, the deviation of the position of said mark from a desired position is sensed and the start of the line recording varied in time in accordance therewith.

摘要： A method for operating a sheet-forming unit of a papermaking machine. At least one fibrous material suspension is fed to a headbox and is conducted in a plurality of turbulence-generating channels to form sub-flows, and fed to a nozzle. From the nozzle, the at least one fibrous material suspension is in the form of a free jet into the forming unit to define an impingement line. In a final fluidization region of an individual turbulence-generating channel a pressure loss (Δp) of ≧50 mbar is generated within the fibrous material suspension before inlet thereof into the nozzle, and the fibrous material suspension is guided from the final fluidization region as far as the impingement line in such a way that the dwell time of the suspension in the region defined by the final fluidization region as far as the impingement line ranges from >30 ms to ≦300 ms.
