A dishwasher includes a drying system that incorporates a mixing conduit that mixes air streams from an exhaust fan that draws humid air from a wash tub, an inlet fan that supplies ambient air to the wash tub, and a gate device that is movable within a range of positions to regulate fluid flow through at least one of first and second inlets of the mixing conduit. A controller may perform a multi-stage drying operation that, in a first stage, controls the gate device while the inlet fan is deactivated, and in a second stage, additionally controls the speed of the inlet fan while controlling the gate device.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems. The treatment fluid can comprise a water-based fracturing fluid or a waterless liquefied petroleum gas (LPG) fracturing fluid.

The invention relates to a facility for treatment of an aqueous effluent by hydrothermal oxidation, which comprises: a reactor comprising a tube in which the aqueous effluent to be treated flows, the tube of the reactor having a plurality of bends formed by oxidant-injection devices, each oxidant-injection device comprising: a reactor part (32) forming an effluent-circulation channel (35) bent at an angle in which a flow of aqueous effluent can circulate, and an injector part (33) comprising a first opening (49) suitable for being connected to a source of oxidant located outside the effluent-circulation channel (35) and a second opening (50) located in the effluent-circulation channel (35), and a source of oxidant connected to the injector part so as to inject the pressurised oxidant into the flow of aqueous effluent to be treated.

In some aspects, the present disclosure pertains to systems for forming hydrogel compositions, the systems comprising a first reservoir containing an iodinated polymer composition that comprise an iodinated polymer having multiple cyclic imide ester groups, a second reservoir containing a buffered diluent solution having a first pH that comprises water, a first buffering agent and a polyamine compound, and a third reservoir containing a buffered accelerant solution having a second pH that is higher than the first pH and comprises water and a second buffering agent. Other aspects of the present disclosure pertain to methods of using such systems for forming hydrogel compositions.

The invention relates to a method and a device for introducing and/or adding non-dry-powder additive materials and/or coating materials with a liquid, solid, semi-solid, or paste-like consistency or in suspended or emulsified form, for example, peroxides, fats, waxes, IV improvers, polymers, or similar materials, to an existing lumpy or particulate material which is moved and mixed, and optionally warmed and reduced to small pieces in a receptacle and/or compressor (1), said material being in particular polymer particles and/or flakes, wood fibers, paper cuttings, or similar materials. According to the invention, the additive material is introduced below the level of the material and/or material particles already in the receptacle (1).

Cartridges for the isolation of a biological sample and downstream biological assays on the sample are provided, as are methods for using such cartridges. In one embodiment, a nucleic acid sample is isolated from a biological sample and the nucleic acid sample is amplified, for example by the polymerase chain reaction. The cartridges provided herein can also be used for the isolation of non-nucleic acid samples, for example proteins, and to perform downstream reactions on the proteins, for example, binding assays. Instruments for carrying out the downstream biological assays and for detecting the results of the assays are also provided.

A package for storage and dispensing of carbonated beverages. In one aspect, the package generally includes a collapsible, flexible liquid enclosure housed within an external container where the external container is precisely configured to correspond in size and shape with the liquid enclosure when the liquid enclosure is filled to the desired maximum volume. As such, the internal liquid enclosure and the external container cooperate to constrain the internal pressure of the filled liquid enclosure. The external container may be generally sleeve-like with top and bottom ends closed by end caps. In one aspect, the liquid enclosure may include a valve fitment seating a conventional Schrader valve through which fluid can be introduced into and dispensed from the liquid enclosure. The present invention also provides a method of filling a package in which the liquid is not carbonated until after it has been introduced into the liquid enclosure.

A delivery system for mixing and dispensing a gel stemming material into a blast hole is disclosed. The system includes a dual-pump assembly in fluid communication with respective sources of a first gel precursor fluid and a second gel precursor fluid; a pair of hoses associated with a means to vary an effective length of said hoses; a dosing head having a first inlet and a second inlet, said inlets arranged in respective fluid communication via said hoses with the dual pump assembly to receive the first and second gel precursor fluids, the dosing head being configured to receive and mix the first and second gel precursor fluids to produce the gel stemming material and to dispense the gel stemming material via an outlet. In use, the effective length of the hoses may be varied to position the dosing head and dispense the gel stemming material in the blast hole.

A treatment device for a liquid may include an air compressor configured to generate compressed air and an air dryer coupled downstream from the air compressor. The treatment device may also include an oxygen concentrator coupled downstream from the air dryer and configured to separate nitrogen and oxygen from the compressed dry air and output the nitrogen to the air dryer. The treatment device may also include an oxygen nanobubble generator coupled downstream from the oxygen concentrator and configured to generate oxygen nanobubbles within the liquid.
