Abstract: A method of simulating feeding movement of a waterfowl decoy in a body of water includes rotating a shaft of a motor of the decoy from a resting position to a first feeding position to cause the decoy to move from a horizontal position to a vertical position, from the first feeding position to a second feeding position to cause the decoy to move from the vertical position to a position between the horizontal position and the first feeding position, from the second feeding position to the first feeding position to cause the body of the decoy to move from the position between the horizontal position and the first feeding position back to the vertical position, and from the first or second feeding position back to the resting position thereby causing the body of the decoy to move back to the resting position.

Abstract: A waterfowl decoy comprises a body having a head portion and a body portion. A motor is coupled to a bottom of the body portion. An elongate rigid member has a first end coupled to the shaft of the motor and a second end coupled to a mass. The elongate member is movable by the shaft of the motor between a first position and a second position. The mass is sufficient to counterbalance the buoyancy of the body to cause the armature to remain substantially vertical in a body of water when the shaft of the motor is rotated causing the head portion of the body to be submerged in the body of water when the mass is pivoted toward the head portion and causing the head portion to raise out of the water when the mass is pivoted away from the head portion.

Abstract: An apparatus and process for testing the uniformity of a papermaking pulp with respect to the lignin associated with individual fibers comprising substantially simultaneous analysis of individual fiber length and fluorescence of the lignin associated with such individual fiber. The ratio of the lignin mass over the fiber length has been found to be proportional to the Kappa Number.
