Abstract
1,241,670. Combine harvesters. CLAYSON N.V. 3 Dec., 1968 [5 Dec., 1967], No. 57199/68. Heading A1F. [Also in Divisions G4-G6] The efficiency of a combine harvester is assessed by counting the number of grains extracted from a sample of material falling from the straw shakers or sieves. This material is subjected to an additional shaking and blowing action to separate the grains from the chaff, the grains falling on to a diaphragm associated with an electric transducer. The resulting signal is passed through a band-pass filter to eliminate noise and shaped before application to a counter in the form of a meter viable to the driver. According to the meter reading the controls of the harvester may be adjusted.
