A structural lining system and a method of applying the system to the interior surface of a pipe. In operation, the client first authenticates to a first proxy using authentication data appropriate for the first proxy. The band is wrapped about the longitudinal axis in a substantially helical manner to form a plurality of helical windings. The other surface of the water-repellent layer faces the gas diffusion layer. The rate controller can operate by measuring the frequency of excitation of a rotational position sensor, and turning the acceleration on or off based on whether the frequency of excitation exceeds a threshold value corresponding to the desired steady state speed. The aperture may be laterally formed in the other end of the crank arm, or formed through the outer peripheral wall of the crank arm and communicating with the orifice of the crank arm.
