An apparatus for providing a liquid component as a first starting component of a bone cement dough from two starting components, comprising a receptacle in which a tank containing the liquid component can be stored, an opening means for opening the tank, a reservoir, fluidically connected to the receptacle, for receiving the liquid component from the tank, at least one port for fluidically connecting the apparatus to a syringe in which a powder component can be stored as a second starting component of the bone cement dough, and at least one conducting means which fluidically connects the reservoir and the at least one port to one another.

A liquid-mixing apparatus used in a liquid-mixing method comprises a plurality of supply valves provided to a cylinder. The supply valves make it possible to individually supply a plurality of types of liquids into a retention chamber. Each of the supply valves is configured so as to be switchable between an open state, in which the interior of a supply channel via which a liquid is supplied and the interior of the retention chamber intercommunicate, and a closed state, in which communication between the supply channel and the retention chamber is blocked. A piston moves in the direction in which the volume of the retention chamber increases while at least one of the supply valves is in the open state, whereby a liquid is drawn into the storage chamber.

One embodiment relates to a device for the production of a bone cement dough from a monomer liquid and a cement powder comprising a cartridge with an internal space; a cartridge head with a dispensing opening; a conveying plunger that is arranged in the internal space of the cartridge and is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a dispensing plunger between the dispensing opening and the conveying plunger that is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a first hollow space, in which the cement powder is arranged; a second hollow space that is bordered by the dispensing plunger and the conveying plunger; a fluid opening that is arranged in the conveying plunger; a feedthrough that connects the first hollow space and the second hollow space to each other, and a closure means that is arranged on a rear side of the dispensing plunger. The closure means projects away from the dispensing plunger and is situated at a distance from the fluid opening. The fluid opening is closable with the closure means. The closure means is mobile in the closed fluid opening such that the fluid opening stays closed, while the conveying plunger is pushable further in the direction of the dispensing plunger.

The present invention relates to a dispenser for viscous materials that includes a static mixer, a first and second receptacle R.sub.1 and R.sub.2 for a first and second viscous material, connected in fluid communication with the static mixer, a first and second actuator configured for discharge of receptacle R.sub.1 and R.sub.2, an electrically or manually operable drive and a mechanical or hydraulic power transmission configured to translate drive motion into first and second actuator motion.

The disclosure herein relates to a microfluidic emulsification device capable of being injection molded. The device may be used for digital droplet polymerase chain reaction (ddPCR). The emulsification device comprises: (a) a cylindrical outer part (4) with two open ends; (b) a cylindrical inner part (1) with a solid bottom and having a circumference sufficient to allow the inner part to be nested within the outer part of the emulsification device, wherein the inner part and the outer part are capable of sliding freely; (c) at least one groove on an interior surface of the outer part or on an exterior surface of the inner part, the groove having a height greater than a gap between the outer part and the inner part when nested; (d) at least one hole (3) in the inner part adjacent to the solid bottom; (e) a radial distribution channel (2) on the interior surface of the outer part or on the exterior surface of the inner part; and (f) a radial nozzle channel at the base of the interior surface of the outer part or at the base of the exterior surface of the inner part.

Provided herein are apparatuses and systems for mixing liquids and suspensions that include vessels with structures that improve mixing while not contacting liquid delivery components. The apparatuses and systems can include a motor drive that allows speed and directional control of rotation of the vessel. The apparatuses and systems can include one or more magnets for separating magnetic beads in a suspension. Also provided are methods using said apparatuses and systems for mixing and separation processes.

A dynamic mixer for mixing a multi-component material includes a mixing rotor capable of being rotated about an axis of rotation, the mixing rotor having a coupling socket configured at an end thereof. The coupling socket has a reception space configured to receive at least a part of a polygonal shaped coupling plug of a drive shaft to transfer torque from the drive shaft to the mixing rotor. The reception space has an inner length in the direction of the axis of rotation and has an inner surface extending over the inner length and surrounding the axis of rotation.

System for dispensing a makeup product, having a dispenser (11) that receives at least two cartridges (30), each one having a reservoir containing a base product, the latter leaving the cartridge via an outlet channel (52) of the cartridge, this outlet channel opening out at the outside of the dispenser or near the external surface thereof.

A system for dispensing at least one makeup product, including a cup and a dispenser for filling the cup from the bottom with at least one product, the cup being secured to the dispenser at least while it is being filled with said product. The method for dispensing and evaluating makeup, including the steps of: allowing a video link to be established, for example over the Internet, from a camera at a first site to a second site, allowing the second site to operate either directly or indirectly a dispenser of such a dispensing system, present at the first site, this dispenser making it possible to vary the colour of mixture dispensed, and allowing a person present at the first site to apply the mixture dispensed and to send to the second site a corresponding image, so as to receive in return information relating to the result of the makeup.

A container with two inner chambers (6, 7) running in its longitudinal direction and separated by at least one partition wall. An aerobic adhesive is stored in one inner chamber (6). A hydrophilic, gel-like activator is stored in the other inner chamber (7); a mixing unit can be attached to the front end of the container. The aerobic adhesive is fed to the mixing unit from the first inner chamber (6), and the hydrophilic activator is fed to the mixing unit from the second inner chamber (7), in a specified mixing ratio via a supply device and mixed together there. This mixture is discharged via an outlet opening (13) of the mixing unit.
