Patent DE-4105046-A1 (DE)
Inventor: SCHEUFLER BERND DR ING
IPC: A01C17/00
Filed: 1991-02-19
Abstract: Currently used to determine the fertiliser-spreader settings necessary to give the required width and density of coverage with a particular fertiliser type are spreader tables or a mobile test bench. In order to provide a simple way of adjusting a fertiliser spreader to the optimum settings, even with fertilisers whose manufacturer is not known or whose properties have been altered by transport or storage, and without the need to spread many tons of fertiliser on test benches, at least one value specific to fertiliser is determined from a small sample and this value is allocated to settings determined for this fertiliser type in parallel large-scale testing. With a known type of fertiliser, the same fertiliser-specific value is determined in the same way and a definite setting determined by comparison. The settings determined in the large-scale testing are stored on a data-storage medium and the fertiliser-specific value is determined by a suitable measurement instrument from the small sample.

Title: Fluid continuous self cleaning appts. for plastic melts - comprises transverse sliding cylindrical element with axially close filters progressively backflushed, for full flow area, on-line filter change and low pressure loss
Inventor: HARTIG GUENTER ING GRAD
IPC: B01D29/03
Filed: 1991-05-17
Abstract: Filter element (4), pref. cylindrical, slides in a bore perpendicular to the flow channel into cleaning chambers. Cleaned fluid flows from the back of the filter element to the outlet opening. Collecting channel(s) and outlet is on the front of the filter for self-cleaning (back flushing). Pref. normal operating position is with one filter in the flow channel. In this position the other filter may be exchanged by removing end cap and pot-shaped sleeve. The whole assembly is moved by plungers progressively until base of sleeve reaches the opposite wall of channel. Both filters lie partly in the flow channel so back pressure in the outlet will force fluid back through that part of filters in line with collecting channels to flush the filter. The uncleaned parts of filters near the bases of sleeves are cleaned by moving the filter element in the opposite direction so e.g. base passes the right-hand collecting channel, though with restriction of the main flow. ADVANTAGE - Min. flow restriction while filter changing/clean

Title: LF noise reduction filter for digital pulse train - extracts low frequency noise signal using low-pass filter and subtracts it from original input to regenerate pulse train
Inventor: CHO YOSHIKI
IPC: H04N7/035
Filed: 1992-02-21
Abstract: The input signal (A) comprising a pulse train modulated over a low frequency noise signal is fed to the non-inverting inputs of a comparator op-amp (1) and a differential amplifier (3) op-amp (2). The differential amplifier is biassed by a battery (5) connected between the output of the op-amp and the inverting terminal and produces an offset signal (AA) comprising the original pulse train/low frequency noise signal and a DC offset level. This offset signal is fed to a lowpass filter, comprising a serial resistor and a capacitor (7) connected to ground (8), where the high frequency pulse train is removed, leaving the LF noise signal (AF). The LF noise signal is then used as a reference signal (VREF) for the inverting output of the comparator, effectively subtracting the LF noise component from the signal applied to the non-inverting input, resulting in a pure pulse-only output signal (G). USE - Removes low frequency noise and ripple signals from digital pulse trains.
