Abstract: A process shutter arrangement for a vacuum process system is disclosed. The arrangement includes a shutter disc having an essentially circumferential outer diameter DDo, a thickness t, a first surface, and a second surface. The disc includes at least three positioning mortises in the first surface near the outer diameter DDo. Each mortise being centered with respect to a radially axis ?1-3 in an xy-plane of the disc and having two long sides a positioned in parallel or right angled to the respective axis ?1-3. A shutter arm includes a bearing sickle with an inner periphery DSi, and at least three positioning tenons near or adjacent to the inner diameter DSi, and corresponding with positioning mortises to position the disc when set on the positioning tenons or on an optional bearing surface of the sickle.

Abstract: A device that dispense dosages of a free-flowing substance has a support column with a horizontal support arm (10) cantilevered thereon. The device includes a holder unit (20) on which at least one movably supported receiving unit (30) is arranged. The receiving unit is designed so that at least one dosage unit (70) can be set into, as well as taken out of, it. The holder unit contains at least one agitation actuator (50) that acts on the receiving unit. The dosage unit can be fastened to the receiving unit by means of a pre-tensioned clamping module (60). For the insertion and/or removal of the dosage unit, the clamping module can be spread apart from a dispensing position into a loading position by means of an opener module that is based on the holder unit. In the dispensing position, the opener module is uncoupled from the receiving unit.

Abstract: A container is filled to a predetermined target mass of a free-flowing substance with the help of a device that dispenses measured doses of the substance. The device has a valve for variably adjusting the mass flow rate of the substance from a reservoir into the container. The device further includes a means for measuring the elapsed time from the beginning of the filling process, a balance for determining the mass of the substance in the container, and a controller unit for controlling the valve. The controller unit includes an adjustment module, and a memory unit wherein a desired mass flow rate is stored. At an elapsed time, if the mass flow rate is smaller or larger than the desired mass flow rate the flow rate is respectively increased or decreased by a flow rate adjustment.

An adaptive filter of the controller unit determines the mass flow rate.
