Abstract: A material and method is provided for lining man-entry sized pipes and securing the lining to the pipe. A plurality of lining panels (10) are positioned along the interior surface of a pipe so as to form a plurality of adjacent wall portions extending through the pipe. The lining panels are each formed with a plurality of T-shaped flanges (20) extending perpendicular to and along said outer wall of the lining panel. A stiffening panel (200) is positioned between at least selected pairs of the T-shaped flanges. The hollow interiors of the stiffening panels are formed to receive and hold grout. The grout when cured provides strength and support for a second layer of grout injected into an annulus between the pipe's inner surface and an outer surface of the lining.
Abstract: In a lock-up piston and damper device for a torque converter, a divider member is provided between the retainer plate and the lock-up piston for supporting springs of an internal circumference in series with springs of an external circumference, thereby obtaining a large torsion angle.
