A device (10), for receiving fluid, having a block (12) which comprises: a chamber (14) comprising a top and a bottom; and a chamber outlet (20) at the bottom of the chamber (14). The block (12) further comprises a magnetic stirrer (30) suspended in the chamber (14), wherein the magnetic stirrer (30) terminates above the bottom of the chamber (14), and is rotatably supported inside the chamber (14). The block (12) further comprises a microchannel (26) fluidly connected to the chamber (14) via the chamber outlet (20). The microchannel (26) may be fluidly connected to a downstream reservoir (24), and an upstream reservoir (22). The device (10) is suited for mixing a bead/cell suspension and an oil-based fluid in the microchannel (26) such that they form an emulsion which comprises a plurality of droplets, wherein at least one of the droplets encapsulates a bead/cell.

A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.

A vacuum pumping system which comprises a plurality of vacuum pumping arrangements for evacuating a flammable gas stream and exhausting the gas stream through an exhaust outlet. A housing houses the vacuum pumping arrangements and forms an air flow duct for an air flow for mixing with the exhaust gas stream output from the exhaust outlet in a mixing region in the housing. An airflow generator generates an air flow through the air flow duct to cause mixing of air with the flammable gas stream to a percentage of the flammable gas in the air flow lower than the lower flammability limit of the flammable gas. An airflow sensor senses the flow of air for determining if the air flow is sufficient to dilute the flammable gas to lower than said percentage.

Devices and methods manually open glass ampules within the devices. One device may include a holder having at least one deformable side wall, a supporting element, and at least one strainer/filter arranged below the holder so that the content of the opened glass ampule may flows therethrough. A first lever of the device may pivot around a first axis and a free end of the first lever may be pressed against the deformable side wall of the holder. A second lever of the device may pivot around a second axis that may divide the second lever into a short lever arm and a long lever arm. The short lever arm may be pressed against the first lever and a glass ampule may be broken open by pressure of the free end of the first lever.

The invention provides an apparatus for generating mist, having: a container adapted to accommodate a liquid, the container having an inlet for receiving an incoming fluid stream into the container, and an outlet via which an outgoing fluid stream exits the container; at least one agitator arranged in the container for agitating the accommodated liquid to generate droplets of the liquid; wherein the agitator is arranged to be driven by the incoming fluid stream, such that the generated liquid droplets are caused by the incoming fluid stream to form the outgoing fluid stream, and subsequently, exit the container. The invention also provides a system for generating mist, having: a plurality of the above described apparatuses, having at least a first apparatus having a first inlet and a first outlet, and a second apparatus having a second inlet and a second outlet; wherein the first outlet is adapted to be connected with the second inlet to thereby allow fluid communication between the first apparatus and the second apparatus.

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.

A dispersing device includes: a casing having a liquid inlet; a rotating body accommodated in the casing and pivotably attached to a rotating shaft from one end of the rotating body; a liquid channel having, on the other end of the rotating body, a passage through which the liquid from the liquid inlet passes, and , inside the rotating body, a segment extended radially around the rotating shaft toward an outer side perpendicular to the rotating shaft and from the other end of the rotating body toward the one end of the rotating body in a direction of the rotating shaft axis and in which a cross section shape perpendicular to the rotating shaft is annular; and one connecting hole in the rotating body connecting the liquid channel with the exterior of the rotating body downstream of the liquid channel.

According to one example, a valve for an apparatus configured to mix bone cement is disclosed. The valve can include a base defining a first portion of a passage. The passage can be configured to allow a component of the bone cement through the valve. The valve can include a projection extending from the base to a base opposing end and forming a second portion of the passage that communicates with the first portion. The projection can have a frustoconically shaped surface that comprises one of an outer surface or an inner surface that forms a part of the second portion of the passage.

Examples include microfluidic devices. Example microfluidic devices comprise a first microfluidic channel, a second microfluidic channel, and microfluidic output channel fluidly coupled to the first microfluidic channel and the second microfluidic channel via a fluid junction. The example device comprises a first fluid actuator disposed in the first microfluidic channel to actuate to thereby pump a first fluid into the microfluidic output channel, and the example device comprises a second fluid actuator disposed in the second microfluidic channel to actuate to pump a second fluid into the microfluidic output channel. The first fluid actuator and the second fluid actuator are to actuate to thereby pump a fluid mixture of the first fluid and the second fluid into the microfluidic output channel.
