The present invention relates to a dispenser for viscous materials that includes a static mixer, a first and second receptacle R.sub.1 and R.sub.2 for a first and second viscous material, connected in fluid communication with the static mixer, a first and second actuator configured for discharge of receptacle R.sub.1 and R.sub.2, an electrically or manually operable drive and a mechanical or hydraulic power transmission configured to translate drive motion into first and second actuator motion.

An agricultural incline conveyor having belt guards extending longitudinally through a curvilinear portion from a tail inlet to a head outlet. The belt guards protect linear edges of a belt within the curvilinear portion during mixing operations. A plurality of mixing baffles positioned within the curvilinear portion induce turbulent backflow of a metered stream of seed being transported through the curvilinear portion. The longitudinal guards prevent the loss of transported seed from entering between the belt and a trough of the curvilinear portion.

An exhaust treatment system for a work vehicle includes a selective catalytic reduction (SCR) system having an SCR outlet for expelling treated exhaust flow therefrom, a flow conduit in fluid communication with the outlet, an exhaust sensor positioned within the flow conduit downstream of the outlet, and a flow mixer positioned upstream of the exhaust sensor. The flow mixer has an end wall defining sector openings circumferentially extending between first and second sector sides and radially between radially inner and outer sector ends. Moreover, the flow mixer has swirler vanes, where each of the swirler vanes extends circumferentially from the first sector side of a respective one of the sector openings and radially between radially inner and outer vane ends. Particularly, the radially outer vane end of each of the swirler vanes is spaced apart from the radially outer sector end of the respective one of the sector openings.

Fluid treatment systems and components are provided for a removal of solid matter from water or other fluids in which a chemical or chemicals may be introduced into the fluid under pressure to coagulate and/or conglomerate the solid materials and cause them to be dropped out of the treatment system and be removed. The fluid treatment system can include: an equalization chamber receiving a wastewater; a clarification chamber receiving a partially separated water from the equalization chamber; a mixing tube having an inlet end and an outlet end; and a sludge detector.

Embodiments of the present disclosure provide a target capturing apparatus and a manufacturing method thereof, and a target detecting method. The target capturing apparatus includes a cavity structure, the cavity structure includes: an inlet portion, an outlet portion and a capture region positioned between the inlet portion and the outlet portion, and the capture region includes a capture component, and a combination specifically combined with a to-be-captured target is included in the capture component so as to capture the target in a sample entering the cavity structure.

A mixing device includes a mixing cavity having a partially open wall and a closed wall. In certain examples, the partially open wall and the closed wall are two separately formed pieces. A downstream side of the mixing device is shaped so as to define a helicoidal groove for circumferentially guiding gas from an outlet opening of the mixing cavity in a downstream direction. An injector sprays reactant into the mixing cavity.

An aftertreatment system for treating constituents of an exhaust gas produced by an engine, comprising: a housing; a selective catalytic reduction (SCR) system disposed within the housing; a reductant injector disposed on a sidewall of the housing upstream of the SCR system and configured to insert a reductant into the exhaust gas; and a vortex generator disposed in the housing, the vortex generator comprising at least one deflector disposed on a surface within the housing, the at least one deflector configured to generate vortices in a portion of the exhaust gas flow flowing over the at least one deflector such that the portion of the exhaust gas remains attached to the surface at a downstream location of the surface.

A spray/gas mixer includes a main body having a circumferential wall defining an inlet opening at one end and an outlet opening at another end; a divider baffle within the main body; a swirl duct having a first end adjacent to the wall and a second end extending to the divider baffle; an injector orifice at the first end of the swirl duct; a swirl promoting means; and a restrictor. The swirl promoting means is arranged between the divider baffle and the restrictor. Gas passing through the swirl promoting means is swirled around the first longitudinal axis (A) before passing through the restrictor. The restrictor is disposed between the swirl promoting means and the second end, forcing gas reaching it from an upstream side away from a peripheral region of the interior towards a center axis of the main body.
