A clock generator for generating an output clock signal synchronized with an input clock signal having first and second adjustable delay lines. The engine assembly may also include a fuel intake line operatively connected to the internal combustion engine. A user of the cellular telephone inputs responses to questions on a display. The body further includes an intermediate layer joined to the uppermost layer, comprising a plurality of bonded ultra hard crystals, and having a wear resistance less than that of the uppermost layer remaining region. The force transmitter is actuated by the actuator to apply a force to rotate the engaging member and change a direction of the force in response to rotation of the engaging member. Subsequent washing and filtration steps can further form parts of this process.
