An apparatus and method to exfoliate a graphite grain is described. A mixture of a graphite grain and a fluid medium are transferred into a vessel. The vessel includes an agitator and a chiller. The chiller chills the mixture such that the fluid medium at least partially solidifies into an ice grain. The agitator agitates the mixture to induce a contact between the graphite grain and the ice grain. The contact between the graphite grain and the ice grain exfoliates the graphite grain.

A device, which serves to separate particles of a bulk material, which is deliverable at an input location and is removable processed in different or at least approximately unitary particle sizes at an output location, includes at least one separating element, which has a metal separating plate with through-openings provided therein, which separating element can be provided with ultrasonic energy and for this purpose is connected to an ultrasonic transducer and which is held by a holding device. The holding device is a mounting shaft, which is held at one end or at both ends fixedly or movably, in particular rotatably and/or axially displaceable, and which at one end or at both ends is connected to an ultrasonic transducer, by means of which ultrasonic energy is couplable via the mounting shaft into the separating element, which is designed to be dimensionally stable.

A device for mixing a medical agent and associated systems and methods are disclosed herein. In some embodiments, the device comprises (i) a housing defining a chamber configured to contain a fluid and having a longitudinal axis, (ii) a plunger assembly at least partially disposed within the chamber, the plunger assembly comprising a plunger and a stirring member extending along the longitudinal axis, and (iii) an actuating assembly operably coupled to the stirring member. The actuating assembly can have an active state in which the actuating assembly causes a distal end portion of the stirring member to rotate at a predetermined speed.

A mixing device for preparing a ready-to-use compound comprising at least one component, which is to be mixed before use, in a cartridge with a tubular mixing rod and a working method with this mixing device and cartridge. The insertion of the cartridge in the mixing device is simplified so that the device can be operated completely automatically, and dispensing of a cartridge to be mixed or a ready-mixed cartridge is preferably be made possible with automated handling means (robots). Because the cartridge holder has a clamping means with which the cartridge can be clamped on the bottle neck-like section, the clamping of the cartridge in the mixer is simplified and can be triggered by force, for example pneumatically.

An electrically controlled mixing and blending apparatus featuring high corrosion resistance and mixing efficiency includes a housing, a first bearing engaged to both sides of the housing, and the interior of both first bearings being coupled to a first rotating shaft, a second bearing engaged to a surface at the middle of the first rotating shaft and the interior of the second bearing being engaged to a surface of an output shaft of a first motor output shaft. Both sides of the first motor are fixedly coupled to a surface of the first rotating shaft through a first fixed rod. A gear drives the first motor, a blending rod and a stirring rack to swing in the front-rear direction through the first rotating shaft to increase the turbulence of the liquid raw materials, reduce the time required for mixing raw materials, and improve the production efficiency.

A surgical system including a surgical tool and a navigation system for tracking the position of the surgical tool. The surgical tool comprising a housing including a variable speed motor and control module disposed within the housing. The navigation system comprising a navigation console in communication with the control module of the surgical tool, the navigation console may be configured to communicate instructions to the control module of the surgical tool based on the position of the surgical tool relative to a defined zone. The navigation console may be configured to deactivate the surgical tool based on the position of the surgical tool relative to the defined zone. The navigation console may also be configured to provide a user-selectable override option to allow continued operation of the surgical tool within the defined zone.

An inventive exchangeable pharmacy formulation preparation device lifting arm (28) for being arranged at a lifting unit (12) of a pharmacy formulation preparation device (2) for preparing an individual pharmaceutical product and for attaching a mixing vessel (32) for such an individual pharmaceutical product thereto comprises a substantially elongated basic body, in which an elongated recess (64) for sliding the basic body onto a lifting unit fixing pin (62) is provided, the elongated recess (64) extending from a first longitudinal end (40) of the basic body over part of the longitudinal direction of the basic body towards the opposite second longitudinal end (42); wherein the first longitudinal end (40) of the basic body comprises a stopping region (45) for a front surface (16) of the lifting unit (12) and a bearing region (44) for a supporting surface (18) of the lifting unit (12); and wherein a fastening unit (30) for a mixing vessel (32) is provided at the or close to the second longitudinal end (42) of the basic body.

Mixing group for mixing two compounds to obtain a mixture, such as bone cement or an acrylic resin or a hydraulic cement, including: a first component having a substantially tubular body and delimiting a first housing zone of a first compound to be mixed, the first component having a first end as well as a second end, a second component with substantially tubular body and delimiting a second housing zone, the second component having a third end as well as a fourth end, the second component being set to contain a second compound to be mixed or a vial for containing a second compound to be mixed, the first housing zone being in fluid communication with the second housing zone, so as to allow the passage of the second compound from the second housing zone to the first housing zone.

A mixing and dispensing system for a two-component material, such as a bone cement, the mixing and dispensing system including a handle connected to the mixer via a mixing shaft. The mixing shaft extends through the piston from the piston driving end in the direction of the outlet end in order to move the mixer in dependence on movements initiated via the handle, and with the handle being detachable, in particular in a non-destructive manner, from the mixing shaft via a connector.
