Systems and methods for the automated demineralization of bone and decellularization of soft tissue include a mixing assembly communicatively coupled with a control and reporting system. The mixing assembly includes a housing that supports a cannister sub-assembly forming a mixing chamber having a reagent inlet, a reagent outlet, and an internal fluid agitator. A motor is operably coupled with the agitator and configured to spin the agitator in first and second directions relative to the cannister, thereby agitating fluid contained within the mixing chamber. At least one pump is configured to progressively inject measured quantities of a plurality of reagents into the mixing chamber. The associated control and reporting system includes a user terminal that displays a graphical user interface enabling a user to initiate an automated demineralization or decellularization procedure in which the mixing assembly demineralizes tissue placed within the mixing chamber. Other embodiments are also disclosed.

Textile fibers at least partially coated with a coating that includes particles of metal-organic frameworks dispersed in a polymeric base are provided. Also provided are fabrics formed from the textile fibers, protective gear and articles of clothing made from the fabrics, and methods of using the fibers and fabrics to catalyze the hydrolysis of organic molecules, such as organophosphate-based nerve agents, having hydrolysable bonds.

The system, in one aspect, includes a first bulk storage container for holding a first bulk dry flowable material having a first dispensing assembly coupled with a first outlet, and a second bulk storage container for holding a second bulk dry flowable material having a second dispensing assembly coupled with the second outlet. The system, in one aspect, may further include a mixed storage vessel, as well as a controller in communication with the first dispensing assembly and the second dispensing assembly, the controller programmed to cause the first dispensing assembly to discharge the first amount of the first dry flowable material to the mixed storage vessel and cause the second dispensing assembly to discharge the second amount of the second dry flowable material to the mixed storage vessel over a comparable time period based upon weight based readings the controller receives from first and second load cells.

A system for dispensing a metered amount of a fiber additive into a concrete mixing system. The system includes a dispensing hopper to hold the fiber additive and to selectively dispense the fiber additive. A discharge outlet is included having an adjustable area formed between a fixed surface and a movable surface. Fiber additive exiting the dispensing hopper passes between the fixed surface and the movable surface. A conveyor and dosing wheel are the fixed and movable surfaces and dispense the fiber additive through the discharge outlet. A sensor senses an amount of fiber additive within the system and a controller controls the amount of fiber additive dispensed from the system. The specific amount is controlled by altering either a speed of the conveyor or dosing wheel or the distance between the fixed surface and the movable surface. As any of the above decrease, fiber additive discharge decreases.

A closed system (100) for mixing fluids for use in a bioprocessing system, comprising: automated means for manipulating a tube weld (160) between a first tube fluidly connected to a first consumable (10-1) and another tube fluidly connected to a mixing consumable (10-3), said tube weld forming a closed fluid connection between the first consumable and mixing consumable; automated means for transferring a first fluid contained by the first consumable to the mixing consumable via the fluid connection; and automated means for determining a quantity of fluid transferred to or from the mixing consumable, wherein the system is further configured to manipulate a tube weld between a second tube fluidly connected to a second consumable (10-2) and said another tube fluidly connected to the mixing consumable, and transfer a second fluid therebetween to be mixed with the first fluid in the mixing consumable.

A slurry homogenization process and a use thereof, including the following steps: performing a first pre-mixing operation on a main material, a first conductive agent, and a binder to obtain a first mixture; adding the first mixture into a first solvent, and sequentially performing a second pre-mixing operation and a first dispersing operation to obtain a second mixture; and adding a conductive slurry into the second mixture, sequentially performing a third pre-mixing operation and a second dispersing operation to obtain a third mixture, and performing a defoaming and cooling operation on the third mixture to obtain a homogenized slurry.

A system for treating exhaust gas of a vessel having at least one engine equipped with a turbocharger includes a storage tank configured to store a powder for treating the exhaust gas, and a dosing assembly fluidly coupled to the storage tank. The dosing assembly is configured to inject the powder into the exhaust gas at or adjacent the turbocharger, and includes a nozzle for injecting the powder into the exhaust gas. The nozzle includes a conduit configured to transport the powder, and a conical member mounted to a distal end of the conduit and defining a central hole in fluid communication with the conduit for guiding a first portion of the powder through the central hole. The distal end of the conduit and the conical member together define an annular gap configured to guide a second portion of the powder through the annular gap.

A cleaning device and a cleaning system. The cleaning device includes: a cleaning base provided with a cleaning roller, the cleaning base being configured to move on a surface to be cleaned so that the cleaning roller cleans the surface to be cleaned; a clear water tank configured to contain clear water; a detergent box configured to contain a detergent; and a dual-head pump configured to pump a first liquid and a second liquid and including: a driving motor; a first pump body mounted on a first side of the driving motor and configured to pump the first liquid; and a second pump body mounted on a second side of the driving motor and configured to pump the second liquid, the first side and the second side being arranged opposite to each other.
