  • Patent number: 6698170
    Abstract: A combined mowing machine includes a main chassis designed to be coupled to a tractor, and a plurality of cutting units connected in such a way that they can oscillate on the chassis. Each set of cutting units has a plate support beam mounted between a pair of end plates fixed to the chassis, and a pin integral with the beam. The pin slides in two slots cut into the end plates to allow the movements of the cutting unit. The mowing machine allows the cutting units to oscillate freely in order to follow the lie of the land, as a result of the double-joint oscillation and the forward/back oscillation in the slots.

  • Patent number: 6669557
    Abstract: An apparatus for measuring at least one parameter of material and generating multiple frequency signals having frequencies selectable by control signals, combining the multiple frequency signals into a combined frequency signal having multiple frequency components, and applying the combined frequency signal as an excitation signal to a sensing element. The frequency response of the material is determined at each of the multiple frequencies using output signals from the sensing element, and a frequency analysis is performed to determine the parameters of the material. The sensing element may include a capaciflector sensor located non-intrusively along the surface of a conveyor. However, other sensing elements such as capacitive, resistive and inductive elements may be used. The parameters being measured may include mass flow rate and moisture content.
