Title: Motion detector for chrominance signal in tv receiver
Inventor: NAKAGAWA ISAO
IPC: H04N9/64
Filed: 1986-11-19
Granted: 1992-02-18
Abstract: ABSTRACT OF THE DISCLOSURE          A motion detector for a chrominance signal which is used with a TV receiver equipped with a video signal motion detector.  This motion detector for a chrominance signal has a delay element for delaying the chrominance signal of a video signal by 1 frame period, a subtracter for subtracting the output signal of the delay element from the input signal thereof, an absolute value conversion circuit to which the output signal from the subtracter is inputted, and a smoother circuit to which the output signal from the absolute value conversion circuit is supplied.  If the chrominance signals of video signals on two consecutive frames are the same, the output signal of the subtracter becomes zero.  If the chrominance signals of video signals on two consecutive frames are different, the output signal of the subtracter takes a positive or negative value.  The negative value signal is converted into a positive value signal by the absolute value conversion circuit.  A signal is outputted from the smoother circuit only when the chrominance signals of video signals on two consecutive frames are different. This outputted signal is a chrominance signal motion detection signal.           The luminance signal contained in a video signal is removed from the video signal using a comb-type filter.

Title: Process for making spun-filament fleece from endless synthetic resin filament
Inventor: REIFENHAEUSER HANS
IPC: D04H3/16
Filed: 1987-11-09
Granted: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE           The process for making the spun fleece proceeds in a filament-spinning unit having a spinning nozzle system, a cooling shaft, a stretching aperture, a diffuser shaft, a continuously moving fleece recovery conveyor and a device for feeding process air and for drawing outflowing air through the fleece recovery conveyor.  The cooling shaft has a shaft wall provided with a plurality of air orifices. That allows process air required for cooling to be fed into the cooling shaft. That air flow at least partially is drawn through the fleece recovery conveyor.  The thickness of the spun fleece is measured on the fleece recovery conveyor in the transport direction downstream of the diffuser shaft. The measured value is compared with a predetermined set value.  On deviation of the measured value from the set value the setting angle of the air control flap or flaps which are located adjacent the entrance of the stretching aperture is changed. On a positive deviation of the measured value of the thickness from the set value the setting angle is increased, on a negative deviation the set value is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE      A measuring canal is provided which is connected to a catheter.  The canal includes a measuring sensor and a reference sensor.  The catheter includes several lumens that have a common opening to the liquid measuring medium.  The flow direction of an infusion solution at the opening is reversible.  A second lumen of the catheter is connected to the measuring canal which is provided with at least one measuring sensor and with at least one reference sensor as well as with a device for setting the outflow of the apparatus to a predetermined velocity.  The flow of an infusion fluid and the liquid medium alternates in such a fashion that during a first time interval the measuring sensor is coupled to the liquid medium and the reference sensor is coupled to the infusion solution.  In a second interval the situation is reversed so that the original measuring sensor is coupled to the infusion solution and the original reference sensor is connected to the liquid medium.  The unique arrangement is effective for blood examination.  Drift problems and toxicity problems cannot occur and no electrochemical reference electrode is required.
