Abstract: An adjustable height boat includes a lower deck and an upper deck, movable relative to the lower deck. The upper deck is configured to support one or more passengers and facilitates movement of the passengers in an upright position. The adjustable height boat include a plurality of telescopic support legs. In one embodiment, the plurality of telescopic support legs includes four columns having actuators therein, which are configured to extend and retract in response to signals received from a controller to move the upper deck from a first position in which the upper deck is a first height above the lower deck and a second position in which the upper deck is a second height above the lower deck.

Abstract: A method of manufacturing a catalyst article, the method comprising: providing a slurry comprising a support material, palladium ions, alkaline-earth-metal ions and an organic compound, wherein the organic compound comprises a functional group selected from a sulfo group (—SO3H), a sulfonyl group (—S(?O)2—) and a sulfinyl group (—S(?O)—); disposing the slurry on a substrate; and heating the slurry to form nanoparticles of the palladium and nanoparticles of a sulfate of the alkaline earth metal on the support material.

Abstract: A three-way catalyst article, and its use in an exhaust system for internal combustion engines, is disclosed. The catalyst article for treating exhaust gas comprising: a substrate comprising an inlet end and an outlet end with an axial length L; a first catalytic region comprising a first platinum group metal (PGM) component supported on a first PGM support material, wherein the first PGM component comprises platinum and rhodium; and wherein the first PGM support material comprises ZrO2—Al2O3.
