Abstract: A torque converter includes an impeller and a cover rotationally fixed to the impeller. The cover has opposing inner and outer surfaces and a through hole extending from the inner surface to the outer surface. A stud is attached to the cover. The stud has a head and a shank extending from the head. The head defines an annular projection circumscribing the shank and raised from the head. The stud is disposed on the cover with the shank extending through the hole to project from the outer surface and with the head being connected to the cover by coalescence between the annular projection and the inner surface creating a hermetic seal around the hole.

Abstract: A torque converter, including: a cover including a first surface facing in a first radial direction; an impeller; a stator; and a lock-up clutch including a piston plate and a seal plate including a second surface in a press fit with the first surface.

Abstract: A dual-exposure heat absorption panel is disclosed, which can be used in a solar receiver design. Generally, the heat absorption panel includes a tube panel through which a heat transfer fluid is flowed to absorb solar energy from heliostats that are focused on the tube panel. A structural support frame surrounds the tube panel. A stiffener structure runs across the exposed faces of the tube panel. The headers and other support structures on the periphery are protected by use of a heat shield.
