An axial adjusting device includes two discs which are rotatable relative to one another and coaxially supported relative to one another, between which two discs balls are guided in pairs of ball grooves. The depth of the pairs of ball grooves is variable across the circumference of the discs. One of the discs is axially supported and one is axially displaceable against resilient returning forces of a first spring mechanism. At least one of the discs can be driven by a motor via a gear drive. A second spring mechanism is provided which—during the return motion of the discs, after the balls have reached their end positions in the ball grooves, which end positions are determined by the greatest groove depth—permit the drivable disc to overshoot against the resilient returning forces of the second spring mechanism.

A device for large-scale lyophilization of pharmaceutical solutions in medical hollow bodies, includes a lyophilization device and at least one camera. Images of at least one pharmaceutical solution to be lyophilized are recorded by the at least one camera. The images may be used for controlling and/or monitoring the lyophilization process.

A coupling assembly comprising a friction coupling a pressure-generating device comprising a pump body member, an axially-displaceable piston loading the friction coupling, and a pressure chamber formed by the pump body and by the piston and filled with a highly-viscous fluid, and with at least one conveying plate being provided in the pressure chamber; and a shear channel with a control member in the pressure chamber, the control member cooperating with at least one conveying plate. In a first embodiment, the shear channel with a control member forms two circumferential grooves of limited length and each covered by one of the two radial surfaces of the conveying plate, thereby forming two shear channels. Passages through the conveying plate connect the two shear channels. In a second embodiment, the shear channel with a control member forms a circumferential groove of limited length which is covered by one of the two radial surfaces of the conveying plate to form a first shear channel. In the shear channel with a control member, there is a circumferential slot of limited length which is covered by the other one of the two radial surfaces of the conveying plate and by a second conveying plate, the latter being designed to form a second shear channel. The first conveying plate includes fluid passages extending therethrough and connecting both shear channels to one another.

A method for filling dual-chamber systems in pre-sterilizable carrier systems includes providing at least one washed, siliconized and sterilized dual-chamber system in a magazine. The dual-chamber system includes respective separating elements separating the two chambers from each other. The magazine accommodates at least one dual-chamber system and is arranged in a container that is sealed with a closing element. The method additionally includes introducing the container into a clean room; opening the container and filling a first chamber of the at least one dual-chamber system; and closing the first chamber. The method further includes filling a second chamber of the at least one dual-chamber system; closing the second chamber; and removing the system from the clean room.

A device has at least one chamber for accommodating a medicament or a sample volume, and has a plunger element which is displaceable in the device. The device includes a syringe or carpule, a multi- or dual-chamber system, an autoinjector, or a pen. Pressure forces resulting from a chemical reaction may be introduced into the plunger element, thereby causing displacement of the plunger element.

A coating device for coating an inside of a hollow body with an atomized fluid has at least one atomizing tube enclosing an atomizing channel. A pressurized propellant gas for atomizing an unatomized fluid can be introduced into the atomizing tube. The atomizing tube has at least one outlet opening and further has at least one hollow needle having a discharge opening for the unatomized fluid. The at least one hollow needle interacts with the atomizing channel and is arranged essentially coaxially thereto. The atomizing tube and the hollow needle form a Venturi arrangement.
