A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

The present disclosure relates to mixing devices included in automotive exhaust treatment systems. More particularly, the present disclosure relates to reducing agent mixers for mixing reducing agents with exhaust streams to induce a chemical reaction between the reducing agent and exhaust gasses to reduce Nitrous Oxides (NOx) in the exhaust gas. Reducing agent mixers in accordance with the present disclosure include reducing agent delivery devices for conducting reducing agents into an internal mixing space through which exhaust gasses flow.

A vehicle exhaust system includes an outer housing defining an internal cavity surrounding an axis, an inlet baffle configured to direct engine exhaust gas into the internal cavity, and an injector that is configured to spray a fluid into the internal cavity to mix with engine exhaust gas. An inner wall is spaced radially inward of an inner surface of the outer housing to define a gap. The inner wall has an impingement side facing the axis and a non-impingement side facing the gap. At least one heat transfer element is positioned within the gap and in is contact with at least one of the inner surface of the outer housing and the non-impingement side of the inner wall to transfer heat through the inner wall to the impingement side to reduce spray deposit formation.

An exhaust line includes a housing having a wall with an opening and a baffle disposed within the opening. In certain embodiments, the exhaust line includes a divider between the wall and baffle that partially defines a mixing chamber for receiving an exhaust and a reducing agent, and partially defines a bypass chamber for receiving another portion of the exhaust. The divider defines an inlet and outlet facing respective upstream and downstream ends. The divider transfers heat from exhaust passing through the bypass chamber to the reducing agent inside the mixing chamber. In other embodiments, the baffle partially defines a first passageway substantially parallel to and offset from a center axis for delivering a portion of the exhaust to the mixing chamber, and a ramped surface partially defining a second passageway transverse to the first passageway for delivering another portion of the exhaust to the mixing chamber.

According to some embodiments, a system and method for dispensing a floor coating in a specified ratio of multiple components is disclosed. The system and method may set and maintain a desired ratio of the multiple components by controlling, with a controller, a drive rate of respective pumps configured for propelling the components from a reservoir to a mixer or a dispenser. The controller may be responsive to at least one of a measured actual drive rate, an environmental condition, an actual usage of each component, and an operational parameter of the system, for adjusting a drive rate of the respective pumps to compensate for discrepancies that may affect the ratio of the multiple components.

A vaporizer includes a vaporization chamber in which a liquid material is heated and vaporized and a heat exchange element arranged in the vaporization chamber. The vaporization chamber has a groove in its inner surface. This helps improve vaporization performance of the liquid material and the vaporization of the liquid material at a high flow rate.

Disclosed cyclonic flow-inducing pumps overcome drawbacks associated with known adverse flow conditions that arise from flow of certain types of materials through a material flow conduit. Such cyclonic flow-inducing pumps provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile such as, for example, increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated adverse considerations such as slugging.

A manifold having a first side, a second side, a first channel extending from the first side to the second side, and a second channel extending from the first side to the second side is disclosed. The first channel and the second channel each define a linear longitudinal axis. In one embodiment, the first channel longitudinal axis and the second channel longitudinal axis are oblique to the first side and the second side of the manifold. The manifold of the present disclosure provides channels that can be easily cleaned and allow for an increased flow performance.
