  • Patent number: 8607724
    Abstract: Disclosed is a rudder assembly formed from a rudder structure having an airfoil shaped rudder structure rotatably secured to a shaft that is rigidly secured an underlying base plate. An upper surface of the base plate includes a support pin positioned a predetermined distance from the shaft. A trailing tab having an underlying drive plate is hingedly coupled to the rudder structure. The drive plate has a centrally located slot constructed and arranged to be slidably secured to the support pin on the base plate. Rotation of the rudder structure results in direct movement of the trailing tab in proportion to the rudder position. Clockwise rotation of the rudder structure causes the clockwise rotation of the trailing tab. Counter-clockwise rotation of the rudder structure causes the counter-clockwise rotation of the trailing tab.

  • Patent number: 6490747
    Abstract: A electric toothbrush attachment consisting of a miswaak element. The attachment is positioned to rotate at ninety degrees from the rotation of the arm. This motion results in a circular movement of the brush element against the surfaces of the teeth. The brush element is mounted on a disk which rotates in response to rotation of arm. The brush element may be fixed to the disk by adhesive. The brush element has a conical shaped end is left in water to provide soft bristles upon use.
