A mixer assembly for an exhaust aftertreatment system includes a first support ring. The first support ring defines a plurality of first slots angularly spaced apart from each other. A second support ring spaced apart from the first support ring defines a plurality of second slots angularly spaced apart from each other. A plurality of blades extends between the first support ring and the second support ring. Each of the plurality of blades is coupled to each of the first support ring and the second support ring. Each of the plurality of blades includes a base. The base includes a first connecting portion engaged with a corresponding first slot from the plurality of first slots and a second connecting portion engaged with a corresponding second slot from the plurality of second slots. At least one tab extends outwardly from the base at an angle relative to the base.

A transmission mechanism suitable for a double-rotating paint mixing machine, comprising a rotating spindle installed on a rack, a pressing spindle installed in the rotating spindle, a guide rail frame fixed at a front end of the rotating spindle, an upper supporting arm and a lower supporting arm, and an upper pressing disc and a lower pressing disc, which are installed on the upper supporting arm and the lower supporting arm and are capable of rotating, wherein the rotating spindle can drive the entire guide rail frame to rotate along the axis of the rotating spindle, meanwhile the upper pressing disc can be driven by a transmission system to rotate around its own axis at the same time, wherein the rotating spindle is engaged with and disengaged from the driving wheel through a driving disc locking device.

A counter-rotating dough making mechanism, including a drive shaft (9) that is provided with an upper dough hook assembly (1) and a lower dough hook assembly (2) is disclosed. The lower dough hook assembly (2) is preferably provided with a stir plate (3) which enhances the thorough mixing of flour during dough kneading. The upper dough hook assembly (1) and the lower dough hook assembly (2) are connected by gears (42a, 42b, 42c) so that they rotate synchronously but in the opposite direction. By the counter-rotating action of the upper dough hook assembly (1) and the lower dough hook assembly (2), the dough making process is more effective as compared to the usual single piece dough hook as used in many stand mixers. The design and construction of the disclosed counter-rotating dough making mechanism is simple, robust, and reliable, and can deliver superior performance in dough making.

Various embodiments herein pertain to apparatus and methods that utilize the water and existing chemicals to generate a foam. The foam can be introduced at that gas-path entrance of the equipment, where it contacts the stages and internal surfaces, to contact, scrub, carry, and remove fouling away from equipment to restore performance. Some embodiments include mixing gas with liquid to create a supply of foam, streaming the foam into a gas turbine engine installed on an airplane, rotating the spools of the engine while streaming, and re-rotating the spools of the engine after a spool has stopped. In yet other embodiments there is a method that includes streaming the foam into an engine installed on an airplane, quantifying an improvement to a family of engines achievable by foam washing, operating a specific engine, determining that the specific engine should be washed, and scheduling a foam washing of the specific engine.
