The present invention is a dust abatement device that secures over a container. Powdery material, such as plaster, cement, grout or the like, is poured through the device, and mixed with water inside the container. The device has a mounting sleeve and radial manifold. The manifold forms a radial pneumatic channel with a circumferentially disbursed air intake that generates a radially uniform airflow to draw in airborne dust that would otherwise escape to the surrounding air. The manifold is connected to a vacuum with an air filter, and generates a dust shield zone above and around the device, which only extends down from the manifold a few inches. The manifold also funnels material and water into the container, and forms an inner eave that spaces material and water from the air intake, and forms a splash guard to retain upwardly projected splashes of material and water inside the container.

A urea preparation machine includes a cabinet, a stirring tank, a filtering portion, a water tank portion and a heating portion. The stirring tank is provided in the cabinet. The filtering portion is provided in the cabinet. An inlet of the water tank portion is communicated with an outlet of the filtering portion. The heating portion is provided in the cabinet, the heating portion is communicated with the outlet of the water tank portion, and an outlet of the heating portion is communicated with the stirring tank. The independent heating portion is used for heating water in the water tank portion, then the water heated by the heating portion is conveyed to the stirring tank for preparing urea, through such installation, the heating portion is capable of heating the water in the water tank portion in time.

An integrated at least two component mixing and delivery system and method for creating a new mixture from a first component contained within a first enclosure and a second component contained within a second enclosure that is contained within the first enclosure and, via a series of operations that mix the two components and enable the application of through an applicator tip the placement of the new mixture on at least one surface or a portion thereof.

A low-cost drug compounding system that can practically fit inside of a fume hood or the like is provided. The system can use a single pump operable in forward and reverse directions (or multiple pumps) to compound complex mixtures particularly including those requiring the creation of solutions from dry or powdered ingredients. A wireless link allows operation of the system remotely. In one embodiment, the system uses a disposable mixing tube set that can be discarded after mixing while still attached to the base ingredient containers used for the compounding thereby minimize the chance of personnel exposure.

A system includes a source, a detector, and a controller. The source is configured to emit electromagnetic energy toward two plies of film. A portion of the emitted electromagnetic energy is within a range of wavelengths. The detector is arranged to detect electromagnetic energy propagating away from the two plies of film. The detector detects electromagnetic energy within the range of wavelengths and generates signals indicative of intensity of detected electromagnetic energy. The controller controls operation of the foam-in-bag system based the signals from the detector. The film is transmissive of electromagnetic energy in the range of wavelengths. When dispensed between the two plies of film, one or both of foaming chemical precursors or foam formed from a reaction thereof is opaque to electromagnetic energy in the range of wavelengths.

A method for producing a suspension, wherein plant parts are comminuted in portions and mixed with water so that the water and the plant parts form the suspension, and a pomace remaining from the plant parts is separated from the suspension. A device for producing a suspension, the device including a mixing chamber and a mixing element in the mixing chamber for mixing a portion of comminuted plant parts with water so that the water and the plant parts form the suspension, and an outlet on the mixing chamber for letting the suspension out of the mixing chamber so that a pomace remaining from the plant parts is retained in the mixing chamber. In order to accelerate production, the plant parts are mashed to a pulp while the water is pressed at a positive pressure through the pulp and through a filter which retains the pomace.

An improved system and method for fluidizing dry powder-based additives into downhole well operations utilizes a dried, low-volume air stream and an ejector nozzle in order to disperse the powders into a liquid stream. In an embodiment, the system can be placed on a powder blending trailer in order to convey additives directly from bulk transport bins into a liquid stream, through the use of an atmospheric pressure hydration tank fitted with a cyclone separator to ensure an even dispersal into the liquid stream.

A mobile chemical mixing plant includes an inlet for receiving fluid; a fluid conduit for conveying the fluid from the inlet; a container for containing a chemical therein; a chemical pump for withdrawing the chemical from the container and directing the chemical into the fluid conduit for mixing with the fluid in the fluid conduit to form a chemical mixture; and a homogenization pump for pumping the chemical mixture in the fluid conduit out of the mobile chemical mixing plant. The fluid conduit connects the chemical pump to the homogenization pump. The mobile chemical mixing plant is fixed to a trailer that is attachable to a vehicle. Because the fluid conduit directly connects the chemical pump to the homogenization pump, the mobile chemical mixing plant does not need an intervening mixing tank for mixing the fluid and the chemical.

Plant for washing and sanitising the udders of dairy animals of the type consisting of a control panel (1), for the management and the control of the entire plant, a tank (2) for water collection and delivery, a motor body (3) for plant management and a brush body (4) for animal treatment, characterised in that ozone generator (5), structure for ozone enrichment of the water delivered by said tank (2) and structure for drying the udders with ozone once the washing has been completed and furthermore provided.
