The invention relates to a device for incorporation of dust-explosive pulverulent materials into readily inflammable liquids, wherein the device includes the following: at least one liquid circuit (10), wherein the liquid circuit comprises at least one liquid vessel (11), a pipeline system (12), and at least one pump (13), and wherein the liquid circuit is designed to accommodate a combustible liquid; at least one powder vessel (30) designed to accommodate at least one pulverulent material (31) to be incorporated into the liquid, and wherein the powder vessel is connected to the liquid circuit, especially to the pipeline system, in a fluid-conducting manner via a powder feed conduit (32).

A multi-blender system for blending liquid and solid particulates together to prepare a fracturing fluid, the blender system can include a plurality of independently operable blender units each having components that can operate with either blender unit. Each component may be a modular blender component mounted to respective independent frames. The independent frames are configured to be independently removable, replaceable and movable to multiple positions in the blender system. In some aspects the multi-blender system can operate at different sand concentrations, instantaneously adjust flow rate to one or more of the components in either blender unit, provide control redundancy, and may continue to operate despite a failure of one of the major components.

A method for embedding a first component in a high molecular weight second component is disclosed. Embedded high-molecular-weight compositions are also disclosed.

A portable bottle having an internal mixing compartment for mixing a powder with a liquid includes a portable drinking bottle housing a mixing compartment. The mixing compartment is formed from a rigid perforated material and extends upward into the drinking bottle from its base. The mixing compartment is accessible through an opening in the base of the bottle, and houses one or more agitators. In use, a particulate material is inserted into the mixing compartment chamber with the agitator and liquid is then added to the bottle. The bottle having an internal mixing compartment is shaken to dissolve the soluble components of the particulate material. The liquid is poured or consumed through the top of the bottle. Insoluble constituents of the particulate material are prevented from exiting the drinking bottle through the top. The agitator facilitates efficient dissolution of the soluble components of the particulate material.

Disclosed are systems and methods for detecting the beginning of a flush volume. A blended fluid is output by a fluid blending apparatus and pumped into a wellbore. The blended fluid transitions from a first composition to a second composition. A blending signal comprising time-varying data relating to characteristics of the blending apparatus or measured from sensors associated with the blending apparatus is received. Based on a first portion of the blending signal corresponding to the first composition, a calibration profile is generated. Based on the calibration profile and a second portion of the blending signal corresponding to the second composition, a transition indicator corresponding to a change in the blended fluid from the first composition to the second composition is determined. Based on the transition indicator, a flush signal indicating the beginning of a flush volume being output by the blending apparatus and pumped into the wellbore is generated.

A device for preparing a gelatin-based product may include a mix tank, a mix pod that is fluidly coupled to the mix tank via a pod spike, and a hot water tank, where the hot water tank is coupled to the mix pod via the pod spike. In at least one example, the pod spike may include an outer tube and an inner tube. In one or more examples, the pod spike of the device may include a hub, where a first end of the outer tube is coupled to the hub. Further, in some examples, a first end of the inner tube may also be coupled to the hub.

One aspect relates to a bone cement applicator having a cartridge with an interior, a cartridge head with a delivery opening, a mixing member which is movable in the interior with a mixing rod. A delivery plunger is arranged in the cartridge and is mounted in the interior and is pressable in the direction of the delivery opening. The delivery plunger rests with an outer cylindrical circumferential surface against an inner wall of the cartridge. A clamping element is arranged on the inner wall of the cartridge in the region of a back side of the interior. The clamping element projects out of the inner wall of the cartridge. The cylindrical circumferential surface of the delivery plunger is resiliently deformable by the clamping element in the direction of a central cylinder axis, such that the delivery plunger is clampable in place with the at least one clamping element on the back side of the cartridge.

The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other or adjacent opposed ends of the deflector blades and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.
