A snow conversion system for removal of snow from an access surface includes a mixing tank and a conveyor apparatus fluidly connected to the mixing tank for transferring the snow from the access surface into the mixing tank. The system also includes a fluid delivery arrangement for injecting a chemical agent into the mixing tank to combine the chemical agent with the transferred snow and thereby generate a solution of the melted snow and the chemical agent. The system additionally includes a mixer for agitating and mixing the snow and the injected chemical agent in the mixing tank to thereby further facilitate melting of the snow in the mixing tank. The system further includes a fluid nozzle in fluid communication with the mixing tank for dispensing the solution of the melted snow and the chemical agent onto the access surface to thereby provide de-icing and/or anti-icing of the access surface.

A mobile aggregate hopper for a volumetric and gravimetric mixer having arcuate longitudinal walls for holding and isolating aggregate. The mobile aggregate hopper has a base integral with the arcuate longitudinal walls with an aggregate transfer conveyor capable of attachment to a trailer or chassis having wheels. The single sheet structure of the longitudinal arcuate side walls minimizes welding and mechanical joints during manufacturing and provides a hopper with high strength and capacity and low overall weight.

The present disclosure provides a method for generating a solution, comprising receiving a solution order. The solution order may comprise one or more order parameters for the solution. The solution order may be inputted into a trained algorithm that outputs one or more solution parameters for the solution. The one or more solution parameters may be used to generate the solution comprising a liquid from a plurality of liquids and a solid from a plurality of solids. The solution can meet the one or more order parameters at an accuracy of at least 90%. The solution may be dispensed.

Presented and described herein is a stroke system (1) for dosing a fluid from a container (3), comprising a piston pump (5) with a piston (7), so that a fluid can be dosed from a container (3) by displacement of the piston (7), and a temperature control device (29) for controlling the temperature of the fluid to be dosed by means of the stroke system (1).

A method of conducting fracturing operations at multiple wellsites in a field. The method may include manufacturing a first fracturing fluid concentrate at a fluid manufacturing plant located at a sand mine of the field using sand produced from the sand mine. The method may also include pumping the first fracturing fluid concentrate from the fluid manufacturing plant to a first well and a second well of the multiple wellsites. The method may further include injecting the first fracturing fluid concentrate into a first well at the first wellsite.

An apparatus and a method for providing active agent compositions from fluid is provided. The apparatus and method allow providing release agents, mold release agents, or lubricants in various compositions, for example anti-tack agents for compounds for the rubber manufacturing or processing industries. A mixing system for providing active agent compositions from fluid includes a mixing assembly and a control device, the mixing assembly including a conveyor and a plurality of pipe assemblies. The mixing assembly is controlled using the control device.

A double shaft paddle mixer, including a barrel chamber, and a first paddle screw and a second paddle screw. The first paddle screw is provided with first paddles and the second paddle screw is provided with second paddles. The barrel chamber includes a crushing zone and a mixing zone. The crushing zone is partly separated from the mixing zone by a partition member. A first inlet is connected to the crushing zone and a second inlet is connected to the mixing zone and an outlet connected to the mixing zone. The double shaft paddle mixer can be part of an arrangement and part of a method for producing paste.

A device and method for preparing a sample for solid-liquid or liquid-liquid extraction are provided. In one embodiment, a device includes a sealed container including an opening for receiving a solid sample and a reservoir. The reservoir includes a solvent or is adapted to receive a solvent. The solid sample and the solvent are mixed in the reservoir and to concentrate at least one component of the sample into the solvent within the reservoir. The concentrate is settled into a solvent layer within the container. The solvent layer is sampled via a port. A method includes introducing a solid sample to a solvent; creating a solution by mixing the solid sample with the solvent; allowing the solvent solution to settle into at least one layer; and sampling within at least one layer.

An integrated blender system includes a skid. The integrated blender system includes a blender assembly, including a blender tub including an outlet, a supply pipe coupled between a suction pump and the blender tub, and an outlet pipe coupled to the outlet of the blender tub. The integrated blender assembly includes a dry product additive system. The dry product additive system includes a skid, a hopper, a pickup funnel, a feeder system, a supply pump, and an eductor assembly. The feeder system may be configured to transport product from the hopper to the pickup funnel. The eductor assembly including a suction inlet, a motive inlet, and an outlet. The suction inlet may be coupled to the pickup funnel by a suction hose. The motive inlet may be coupled to the supply pump by a motive fluid hose. The outlet nozzle is positioned to eject fluid and product into the blender tub.

An assembly for insertion into a holder of a mixer, comprising: a dispenser having an exterior surface of which at least a band is symmetric about a longitudinal axis of the dispenser; and an adapter for surrounding at least the band of the exterior surface of the dispenser. The adapter comprises a closeable shell, the shell being configured to lock the dispenser in at least a region of the band so as to impede rotational slippage of the dispenser relative to the adapter about the longitudinal axis with the shell being closed. If the assembly is then locked to/engaged with the holder of a planetary mixer, this causes the assembly to undergo superimposed revolution and rotation movements in tandem with those of the holder, resulting in a desired level of mixing being imparted to the dispenser's contents, which may improve homogeneity and predictability of the mixing results.
