Abstract: Abstract The present invention relates to a venturi scrubber for dust-laden gases.  The scrubber has an inlet stage which in turn has a gas flow channel which tapers constantly in the direction of the flow, and annular channel for a liquid which is arranged at the end of greatest diameter of the inlet stage.  The annular channel is connected around its complete circumference with the channel of the inlet stage through which the gas flows.  At least one feed line is provided for the liquid opening, in the main, tangentially into the annular channel.  The annular channel which is under pressure, is connected through a passage gap with the channel of the inlet stage through which the gas flows.  This pas-sage gap is so configured and arranged that the liquid emerges, in the main, parallel to the adjacent area of the walls of the channel and along these.  In this way it is ensured that a thin and even film of liquid flows over the walls of the channel.  This film of liquid prevents any deposits of solid particles from build-ing up on the walls and forming encrustations thereon.

Abstract: ABSTRACT            An  improved  multisensor  of  the  vibrating-mass  type.          Accelerometers  are  mounted  in  parallel  beam  suspensions  with their input axes substantially collinear.  Forces are applied to the acclerometers through piezoelectric elements mounted to the suspensions to induce vibration so that coriolis rate information is  included  in  the  output  of  the  system. Output  circuitry discriminates between rate and linear acceleration information so that enhanced sensitivity to each parameter is obtained without confusion between coriolis and linear acceleration forces even when  the  frequency  of  linear  acceleration  is  close  to  the modulation vibration frequency.

Color signals R,G,B and the sum signal (GS) are matrixed to form chrominance components and luminance components of a standard composite video signal (e.g. I,Q, YS for NTSC) in a matrix 812. One of the chrominance components (I) is comb filtered (1112) to remove portions of its frequency spectrum. The difference signal (G.DELTA.) is comb filtered (1122) to be inserted (1124) into the removed portions of the chrominance component (Fig 11). The other component (Q) is filtered similarly and a filtered independent signal inserted into it when the rate of change of luminance (G.DELTA.) is large, or alternatively only the independent signal is inserted into the chrominance components when G.DELTA. is large.
