A device for storing first and second ingredient materials, mixing the ingredient materials to form an adhesive material and dispensing the adhesive material. The device comprises: a nozzle for dispensing the third material; a first container adapted to store a first ingredient material and mix the first ingredient material with a second ingredient material; a second container disposed within the first container, and moveable between a storage position in which a second ingredient material is stored in the second container and a mixing position in which the second ingredient material is moved to the first container; a mixer that longitudinally extends into the first and second containers; a handle alternatively coupled to the mixer to mix the first and second ingredient materials or to the second container to move the second container to a dispensing position to dispense the third material. During use, the first container is rotated causing the second container to move relative to the first container and the second material to flow into the first container for mixing. After mixing, the handle is uncoupled from the mixer and coupled to the second container to dispense the third material from the nozzle. Embodiments are also described herein for a method of making the device and a method of using the device.

A liquid-liquid mixing device (10, 210) includes a barrel (20, 220) with a liquid port (23) at or adjacent one end. A plunger assembly (30) is reciprocably moveable along an axis in the barrel (20, 220) and includes a seal member (31, 231) and an agitator (50, 250). The seal member (31, 231) is in sealingly slidable engagement with the internal wall of the barrel (20, 220) to define a variable volume chamber (24, 224) therein in communication with the liquid port. The agitator (50, 250) is reciprocably moveable in the variable volume chamber (24, 224), which agitator (50, 250) includes one or more end to end passages (54) through which liquid in the chamber (24, 224) is forced as the agitator (250) reciprocates in the chamber (24, 224). The device (10) also includes a mode selector mechanism (60, 28, 46, 64, 65, 90, 92, 94, 96) for selection between at least two modes of operation for the plunger assembly, wherein the mode selector mechanism (60, 28, 46, 64, 65, 90, 92, 94, 96) is adjustable between two or more modes whereby movement of the plunger assembly (30) effects either movement of the agitator (50, 250) with the seal member (31, 231) or movement of the agitator (50, 250) relative to the seal member (31, 231), depending on the selected mode.

This invention relates to a particle extractor assembly 10, 100 which is used to extract and collect dust and/or other airborne pollutants from a workface. The assembly 100 is mobile as is mounted to a base 12 which includes a first platform 12.1 and a second pivotal platform 12.2 which is articulated to the first platform 12.1 and is configured to be pivotally displaced relative to the first platform between a lowered position and a discharge position in which it is inclined with respect to the first platform 12.1. The assembly also includes a vacuum pump 150 powered by an electrical motor 160, a particle filter 200 to filter out particles upstream of the vacuum pump and a drum arrangement which includes a collector drum 170 configured to rotate about an axis to mix its contents to form a slurry and it discharge the contents when in the discharge position.

A microfluidic device and a system comprising such a microfluidic device or chip and a method for mixing and distributing fluids using said chip or system, wherein the microfluidic device for mixing and distributing fluids, formed by bonding of a first substrate and a second substrate, wherein open formations on bonded the first and second substrate form at least part of a microfluidic channel network comprising at least one microstructure comprising a single receiving chamber which is connected by at least one first channel extending from said single receiving chamber leading into an at least first target chamber, wherein the at least one first channel extends clockwise or counter clockwise from the single receiving chamber and is bowed in a clockwise or counter clockwise direction.

A manual mixer serves to facilitate mixing and agitating materials for use during surgery. The manual mixer includes a mixing assembly and an actuation assembly for actuating the mixing assembly. The mixing assembly includes at least a paddle portion and a plunger portion. The plunger portion is simultaneously capable of rotational movement with the paddle portion and movement upwardly or downwardly along the paddle portion. Rotation of the paddle portion serves to facilitate mixing and agitating of the materials, and downward movement of the plunger portion serves to facilitate dispensing of the materials from the manual mixer.

A bone cement delivery system including a mixer, a reservoir for holding bone cement, a cannula that is connected to the reservoir and through which the bone cement is delivered into living tissue. A plunger that is advanced by a drive assembly, pushes the bone cement out of the delivery tube into the cannula for discharge from the cannula. A valve is located upstream of the cannula. A control unit regulates both drive assembly and the setting of the valve. The control unit is configured to, when deactivating the valve so as to stop the advancement of the plunger, close the valve. The closing of the valve reduces the extent to which the bone cement, which is under pressure continues to flow into and be discharged out of the cannula.
