A valve comprising a valve spindle housing located in the side of the chamber and including a first fluid inlet and a first fluid outlet, and a cylinder open along a portion of a longitudinal axis of the cylinder and rotatably mounted in the valve spindle housing. The cylinder is positioned in one position so that the cylinder completely obstructs the valve spindle housing outlet, not allowing any fluid to pass around the cylinder. The cylinder walls are solid except for having openings through a portion of the cylinder, so that when rotated to a closed position, the solid portion of the cylinder fully obstructs the valve spindle housing outlet, and when rotated to an open position, the first fluid can pass into the inside of the cylinder and then through the openings and out of the valve spindle housing.

A constrictor valve can be associated with a conduit in fluid communication with a mixer to control a flow of cementitious slurry discharged from the mixer through the conduit. The constrictor valve can include a constrictor housing, a webbing constriction assembly, and a drive mechanism. The webbing constriction assembly includes a pair of rotatable members rotatably mounted to the constrictor housing and a plurality of webbing straps connected to the rotatable members and wrapped around the conduit. The drive mechanism includes a drive shaft and a gear assembly configured to rotate the rotatable members in opposing winding directions in response to the drive shaft rotating in a tighten direction to wrap the webbing straps tighter around the conduit to compress it and to rotate in opposing unwinding directions in response to the drive shaft rotating in a loosen direction to loosen the grip of the webbing straps on the conduit.

Device and method embodiments discussed herein may be used to enhance a brewing process, steeping process or infusing process. Such infusion processes may be used for making coffee, tea, oil, alcohol or any other suitable infused liquid where a user desires to enhance or control such a process.

A volatiles consuming eductor system for coated scrap metal furnaces with separate delacquering and melt chambers. Motive gas is forced through an inlet into a mixing chamber in a direction opposite a suction port, creating a Venturi that draws gases from the delaquering chamber through the mixing chamber. The motive gas and the drawn gases mix and are forced through a discharge port, ignited, and injected into the melt chamber to help heat the melt chamber. A computer monitors process conditions and controls a regulator that adjusts the motive gas flow in response to those conditions.

An apparatus for mixing a first fluid into a flow path of a second fluid, the apparatus comprising: a chamber enclosing the flow path, the chamber including a second fluid first inlet for receiving its respective fluid. The apparatus also includes a second inlet arranged downstream of the first inlet and receiving the first fluid, as well as an outlet arranged downstream of the second inlet for discharging a mixture of the first fluid and the second fluid. The second inlet flows into the flow path and is formed by a shared fluid injector mounted transverse to the axial direction that one fluid and the two fluid flows through its chamber. The flow path includes two respective throttle bodies, each of which is pivotally arranged inside the chamber and attached to opposed sides of the chamber for controlling the flow area of the flow path.

The invention relates to apparatus and a process for mixing a gas/vapour with a process liquid comprising a material and a carrier liquid. The apparatus comprises a passage (10) of polygonal cross section having an inlet (14), an outlet (16) for a process liquid comprising the material, and a nozzle (24) for introducing supersonic gas/vapour at a mixing zone (42) in a single plane.

Provided are methods, systems, and apparatuses for instituting a quiet blending mode. A method includes capturing, via at least one sensor, one or more sound and/or vibration inputs from a blender, comparing the one or more sound and/or vibration inputs to a threshold parameter, and transmitting a command to a blender motor to reduce power when the one or more sound and/or vibration inputs exceed the threshold parameter.
