Patent EP-0210773-A1 (EP)
Inventor: AWAMOTO SHIGERU
IPC: H04N5/919
Filed: 1986-07-11
Abstract: A signal processing circuit for a video recording and reproducing apparatus comprises a ramp inserting circuit (17) for inserting a ramp waveform at periodic intervals into a video signal during recording. The ramp waveform varies linearly as a function of time from the minimum to the maximum level of the video signal. On playback, the inserted ramp is periodically detected from a reproduced video signal by a ramp detector (56A, 56B). The waveform of the detected ramp is corrected to improve its signal-to-noise ratio by an averaging circuit (70, 70') and applied to a transfer circuit (71, 72,73) having a transfer function describing the relationship between the original ramp waveform and the corrected ramp waveform. The waveform of the reproduced video signal is transformed according to the transfer function.

Abstract: Filter press (10) for separating liquids from clarification or industrial sludges in which several press elements (11, 12) are provided as single-chamber filter presses which are arranged successively in the direction of transport of an upper and lower filter material (21, 22), forming, during operation, the inner lining of the press chambers, and can be closed and opened by means of a hydraulic drive cylinder (29). The upper diaphragm plates (18) of the press elements (11, 12) are designed as press punches movably guided in closing pieces (17) by the pressing stroke of which the sludge cake enclosed between the filter materials (21, 22), said cake being fed into the pressing chamber at a pressure of about 2 bar, can be squeezed together, thus ensuring a higher content of solid matter in the sludge cake obtained. The upper filter material (21) is divided up into segments (21') which are connected by attachment seams (62) in a tension-resistant manner but can easily be detached from one another. These filter material segments have projections (63) in the form of truncated pyramids which, when the pressing chambers are filled with sludge, assume a convex shape and can be applied with a large surface area against the diaphragm plates (18) which limit the pressing chambers on the upper side and against the closing pieces/walls (17', 17''). The filter material segments (21) are made from a thermoplastic fiber fabric and the projections (63) are made by a deep-drawing process.
