A two component adhesive system pumps a first adhesive component and a second adhesive component into a replaceable mixing unit that can be periodically replaced when the adhesive has cured in the mixing unit. The adhesive system has a robotic arm coupled to a gripper unit which has an open position and a closed position. In the open position, the gripper unit releases the mixing unit allowing the mixing unit to be replaced. The robotic arm moves the gripper unit to install a replacement mixing unit. The gripper unit can be moved to the closed position and the adhesive can be pumped through the mixing unit.

A cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanical mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

An automatic height adjusting robot has a base frame, an L shaped lifting base assembly, a lifting frame, a hoist assembly, an automated mixing assembly, a power inlet, and a screw conveyor. The automatic height adjusting robot computes controlled volumetric ratios of dry chemicals while connected to a production well.

A method for processing a fluid includes removably securing a retention member to a vessel that bounds a chamber; inserting a collapsible bag within the chamber of the vessel; securing the bag to the retention member so that the bag is supported within the chamber of the vessel; and dispensing a fluid into a compartment of the collapsible bag supported within the chamber of the vessel. The fluid can be mixed within bag while the bag is disposed within the vessel.

An installation for storing, metering, and dissolving water-soluble polymer particles, in particular for enhanced oil and/or gas recovery operations, includes a so-called polymer dissolution container A and at least one so-called polymer storage and distribution container B positioned upon container A. The bottom of container B and the roof of container A each have an opening facing one another allowing the passage of the polymer from container B into the supply mechanism of container A. The installation further includes a connection mechanism able to work with the polymer supply mechanism.

A mixing system includes a container having a support plate and a mixing assembly supported on the support plate. The mixing assembly includes a pliable enclosure containing a fluid and a mixing device. A portion of the mixing device extends from the pliable enclosure and is adapted to be detachably coupled to a drive mechanism. A first plate is detachably secured to the rigid container. The pliable enclosure is disposed between the first plate and the support plate. A mixing arrangement includes a docking station having a drive cradle and a drive mechanism. The mixing system is removably positioned within the drive cradle so that the drive mechanism is removably coupled to the mixing device.

The present invention relates to a biological material extraction apparatus. According to the present invention, a tube in which a solution for use in extracting a biological material is contained is rotated to directly mix the solution, and cells where stirring is being conducted in each step are sealed to fundamentally block stirring-induced pollution between cells, thereby improving an extraction efficiency.

A method of mixing a crosslinking blend in a portable tote for use to crosslink polymer modified asphalts. The method includes providing a portable tote, where the tote includes a tank having a sidewall, a top and a bottom portion. Fixedly positioned partially within the tank interior is an air mixing system that includes a hollow wand that has a distal and a proximal end. The proximal end of the wand exits the tank. The distal end of the tote is connected to at least one accumulator plate, where the accumulator plate is adjacent to the interior bottom portion of the tank. Stored in the interior of the tank is a crosslinking blend suitable for use to crosslink polymer modified asphalts. The method includes the steps of attaching a pulsed gas controller to the proximal end of the wand and coupling a source of compressed gas to the controller, then activating the controller to cause mixing of the crosslinking blend by pulsing gases into the crosslinking blend for a sufficient period of time. After, or during mixing, the crosslinking blend is discharged from the interior of the tank, and the controller is removed from the wand, leaving said wand attached to the tank.
