Link 3, turning about fixed axis B, is connected by sliding pairs to sliders 2 and 4. Slider 2 is connected by a turning pair to slider 5 which moves along fixed guide l-l. Link 6, connected by turning pair F to slider 2, moves in slider 7 which turns about fixed axis A. Link 1, turning about fixed axis 0 , is connected by turning pair D to slider 4. Sliders 8 and 9, connected together by turning pair K, move along the axes of links 6 and 1 . If 2p>q>0 then, when sliding link 1 rotates about axis 0 , point K describes an ellipse with the equation x²/(((q+r-p)²p²)/(2p-q)²)+y²/((q+r-p)²q)/(2p-q)=1 where p=B͞0 q=A͞0 r=0͞D
