Systems and methods for making gypsum board using a liquid gypsum set accelerator. Stucco and water are mixed to form a gypsum slurry, such as in a pin mixer. A gypsum set accelerator is mixed with a liquid medium to form a liquid gypsum set accelerator, such as in an eductor. The liquid gypsum set accelerator is added to the gypsum slurry, which is shaped to form the gypsum board.

An injector is provided to inject an aqueous urea solution into an exhaust line. The injector comprises a single fluid inlet, an injection passage, fluidly connecting the inlet to the injection port, and a shut-off device for the injection port. The shut-off device further comprises an actuator that is configured to selectively move a shutter between open and closed positions. A cooling passage is fluidly connected to the injection passage and is configured to cool the actuator. A fluid pressure regulator is interposed in the cooling passage.

A dispenser head for in-line mixing and dispensing of beverages, which may be carbonated or nitrogenated. The dispenser head comprising a pump, a dilution mechanism, an additive mechanism, and outlet nozzle and optionally a regulation system. In use, the pump can pump concentrate liquid for the liquid product from a concentrate source to the dilution mechanism; the dilution mechanism can receive diluent liquid suitable for the liquid product from a diluent source, operable to mix the diluent liquid and the concentrate liquid and provide diluted concentrate liquid; and the additive mechanism can receive additive fluid for the liquid product from an additive source, to combine the diluted concentrate liquid and the additive fluid. The regulation system comprises a pump regulator means for regulating the quantity of concentrate liquid pumped into the dilution mechanism within the dispense period; a diluent quantity regulator means for regulating the flow of diluent liquid into the dilution mechanism; and an additive quantity regulator means for regulating the flow of additive fluid into the additive mechanism. Preferably, the dispenser head is a unitary device, which may be supplied attached to a vessel containing the concentrate.

A mixing device for mixing at least two different types of liquids of different ingredients suitable for being placed within a tap spout, preferably at a spout outlet, comprising at least two inlets configured to receive the liquids. The mixing device is adapted to deliver liquids separately at the same time such that the liquids mix at an outlet of the mixing device. The mixing device may further comprise a mixing space adapted to mix the liquids received at the inlets and deliver the mixture of the liquids, or deliver one type of liquid through the mixing space when only one type of liquid is received at the inlets, at the outlet of the mixing device. Each of the inlets is connected to a respective conduit that is fluidly separated from the other conduits. The present invention further relates to mixing tap systems using such a mixing device.

Systems for managing abrasive media in cavitated fluid include a set of sensors in communication with cavitated fluid in a processing tank and a processor coupled to the set of sensors. The processor is configured to determine a density of an abrasive media in the cavitated fluid in the processing tank and facilitate maintaining the density of abrasive media in the cavitated fluid in the processing tank at a level that is greater than or equal to a threshold level of abrasive media. The processor is further configured to command the abrasive media addition device to add the recycled abrasive media to the processing tank to increase the density of abrasive media in the cavitated fluid in response to determining that an average density of abrasive media is less than the threshold density of abrasive media.
