Abstract: A golf club head comprising a variable thickness profile comprising a thick central portion; a transition portion; and a thin perimeter portion; wherein said transition portion surrounds said thick central portion; wherein said thin perimeter portion surrounds said transition portion; wherein said thick central portion comprises a center, said center of said thick central portion located equidistant from a heel most portion of said thick central portion and a toe most portion of said thick central portion; wherein said center of said thick central portion is offset from said geometric center of said striking face.

Abstract: A method to extract hot exhaust gas from the exhaust flue and use its heat energy to vaporize aqueous reactive reagents such as aqueous ammonia or to provide a heated air process gas mixture. Compressed air provides motive force to induce a vacuum in an ejector venturi device which draws hot exhaust gas (“hot gas”) from the exhaust flue. In one embodiment the hot gas is drawn into a vaporizer unit. The heat energy in the hot gas vaporizes the injected aqueous reagent. The vaporized mixture is drawn into the ejector and is entrained in the motive air. The diluted reagent vapor mixture is injected back into the exhaust flue to support the selective catalytic reduction (SCR) process and reduce nitrogen oxide (NOx).

Abstract: A secondary latch assembly includes a mounting bracket, a release hook pivotally mounted to the mounting bracket, and a handle mechanism pivotally mounted to the mounting bracket. The release hook is movable between a locked position and a released position and has a slot having a first end and a second end. The handle mechanism has a rotation stop that is positioned within the slot of the release hook and that is movable between the first and second ends of the slot. The handle mechanism is movable between a first position where the rotation stop is positioned at the first end of the slot, a second position where the rotation stop is positioned at the second end of the slot, and a third position wherein the handle mechanism is rotated from its second position while the rotation stop is positioned at the second end of the slot so that the rotation stop urges the release hook from its locked position to its released position.
