A monolithic three-dimensional fluidic check device is presented. The monolithic three-dimensional fluidic check device comprises a housing surrounding a fluidic flow path and having a first opening at a first end of the housing and a second opening at a second end of the housing, and an elongated center body positioned within and extending along the fluidic flow path. The elongated center body is stationary relative to a flow of fluid.

Disclosed herein are apparatuses and methods for conducting multiple simultaneous micro-volume chemical and biochemical reactions in an array format. In one embodiment, the format comprises an array of microholes in a substrate. Besides serving as an ordered array of sample chambers allowing the performance of multiple parallel reactions, the arrays can be used for reagent storage and transfer, library display, reagent synthesis, assembly of multiple identical reactions, dilution and desalting. Use of the arrays facilitates optical analysis of reactions, and allows optical analysis to be conducted in real time. Included within the invention are kits comprising a microhole apparatus and a reaction component of the method(s) to be carried out in the apparatus.

A truck for loading emulsion explosive in field with intrinsic safety, with its key improvement being a static emulsification device and a static sensitizing device to perform emulsification and sensitization, wherein, an outlet of the static emulsification device is connected with a transporting hose, a terminal end of a sensitizer storage transporting system is connected to a starting end of the transporting hose, and the static sensitizing device is arranged at a terminal end of the transporting hose. Its advantages include the transporting of emulsion explosive product is avoided, thereby reducing safety risk; on the other hand, the emulsification device and sensitizing device utilized by this truck both have static structure, so that there exists no shear or mechanical friction during the emulsification and sensitizing process, thereby reducing sensitivity, preventing explosion form happening in the production process, and ensuring production safety.

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 present invention relates to a method for producing and delivering a gas mixture having a selected composition of a first gas and at least one second gas, comprising the following steps: (a) providing a main gas flow comprising the first gas in a main conduit, (b) separating the main gas flow into a first plurality of secondary gas flows, (c) guiding each secondary gas flow through a secondary conduit, (d) adding at least one second gas to at least one of the first plurality of secondary gas flows in the respective secondary conduit through a delivering conduit, said delivering conduit protruding into the secondary conduit, and (e) combining the first plurality of secondary gas flows to the gas mixture. With the technical teaching of the present invention a dynamic gas bottle filling is possible wherein the second gas components may have a concentration form some ppb to percent.

A method and apparatus for obtaining a product chemistry from a slid block of caustic material is provided. The product is housed within a capsule which is positioned inside a turbulent flow dispenser, which utilizes fluid to erode the block and produce a concentrated solution. The fluid characteristics can be adjusted in the field to achieve a predetermined concentrate level of the solution. The capsule provides a safe and convenient means for handling, storing and shipping the caustic block without exposing the operator or handler to the hazardous material. The capsule includes nested components which can be rotated between a closed or sealed position and an open use position.

An antibody-resin coupling apparatus quickly and efficiently activates resin beads and couples them to antibodies, while preventing breakdown and crosslinking of the beads, thereby improving downstream column purification processes, extending the usable life of the resin beads, and increasing molecule capture efficiency of the resultant resin-antibody complexes, to allow improved isolation and purification of factor VIII molecules or other drug compounds.

A system for allowing gas to flow into a liquid, the system comprising: a container having a bottom wherein the bottom comprises a gas inlet; a lid configured to cover the container; a gas providing mechanism configured to allow flow of the gas through the gas inlet into the liquid when contained in the container, and a locking mechanism configured to ensure flow of gas into the liquid only when the container is properly covered by the lid. Additional embodiments of the system are disclosed herein.

This disclosure features methods of forming chemical compositions. The method includes (1) mixing a plurality of continuous material flows in a mixing tank to form a chemical composition, each continuous material flow including at least one component of the composition; and (2) moving a continuous flow of the chemical composition to a packaging station downstream of the mixing tank. The mixing and moving steps are performed continuously. This disclosure also features systems that can be used to perform such methods.
