A dropper machine for pouring a measured amount of a substance in a plurality of receptacles, including: a reservoir containing the substance to be dropped, cylinder and piston metering devices, a drive unit arranged to simultaneously drive the piston of the metering devices wherein each of the metering devices is associated with a respective actuating device cooperating with the piston of the metering device, the actuator device being operable individually to inhibit the delivery of the substance to be dropped through the nozzle when the drive unit is actuated to cause displacement of the pistons of the metering devices associated therewith between the start position and the end position.

The present invention involves a fill needle system for aseptically dispensing a pharmaceutical fluid in an aseptic chamber comprises a fill needle tubing in fluid communication with a pharmaceutical fluid source via flexible tubing and extending through a fill needle hub; a fill needle dispensing tip disposed at a dispensing end of the fill needle tubing; a fill needle sheath shaped and arranged to removably mate with and seal aseptically to the fill needle hub to form an aseptically sealed volume enclosing the dispensing tip; and a fluid pressure pulse induction system disposed and configured to compress the flexible tubing in order to dislodge droplets of pharmaceutical fluid retained on the dispensing tip after halting dispensing of the pharmaceutical fluid. An associated method of dispensing pharmaceutical fluid comprises operating the fluid pressure pulse induction system to dislodge the droplets. The system may comprise a controller for automatically controlling the dispensing and droplet dislodging.

An exemplary dispenser includes a housing and a refill unit. The refill unit being removable and replaceable. The dispenser also includes a processor, memory, a dose count stored in memory that is indicative of the number of doses in a full refill unit, a level sensor for detecting a predetermined level the refill unit and a dispense count indicative of the number doses of product dispensed from the refill unit. In addition, the dispenser includes memory and has logic stored in the memory for recalibrating the number of doses remaining in the refill unit as a function of the dose count, the number of doses of product dispensed and the predetermined level of product. The number of doses of product remaining in the refill unit may be displayed on the dispenser, on a remote station, or on both the dispenser and a remote station.

Device for metering powder, in particular in clean-rooms, which includes a vessel containing powder and a sealing head with a septum for the vessel, wherein the sealing head is connectable powder-tight with the vessel and the septum powder-tight with the sealing head and the device further includes a vessel holder, which serves to hold the sealing head of the vessel, and the vessel with its opening points downwards, so that the powder can flow out of the vessel, wherein a gap is provided between the sealing head and a holding bowl of the vessel holder, in which a gas flow between the holding bowl and the sealing head can be created. The invention also relates to a use of the device and a metered addition method.

An improved particulate metering system is provided. The system includes a flow path having an inlet in communication with an intake and an outlet in communication with a discharge. The flow path receives a first input and a plurality of inputs, each of the plurality of inputs having a separate origin. A mixing area within the flow path comprises a confluence of the first input and one or more of the plurality of inputs. One or more metering controls are in operable communication with the first input and the plurality of inputs for controlling a blend of the plurality of inputs at the confluence.

A system includes an agricultural metering system a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The first meter roller segment includes a first profile, the second meter roller includes a second profile, and the first profile is different from the second profile. The system also has a dividing ring axially positioned between the first meter roller segment and the second meter roller segment.

A sliding cover for a liquid delivery device, such as a cap (100) for a pen injector (200), incorporates a set of sensors including a first optical sensor (110) with an output which changes during uncapping or capping motions on passing of a plunger (220) of the pen injector. This output is used together with at least one additional sensor output to determine the position of the plunger along a cylinder (210) of the liquid delivery device. By monitoring changes in the plunger position, the quantity of dosages delivered by the liquid delivery device can be determined, displayed, stored and/or transmitted to an external device for further data processing or storage.

A drop-detection device detects a drop that escapes from a metering valve. The drop-detection device includes a light guide with first and second light-guiding elements that are arranged opposite each other at an intermediate space. A drop trajectory runs through the intermediate space such that a light beam sent out by the first light-guiding element crosses the drop trajectory and is subsequently coupled into the second light-guiding element. In addition, the drop-detection device includes a light-signal generation device that couples a pulsed light beam with a carrier frequency into the first light-guiding element. Furthermore, the drop-detection device also has a light evaluation device for evaluating the light beam coupled into the second light-guiding element to determine if a drop has been dispensed by the metering valve. A method of detecting a drop is also described.

A dispenser device includes: a valve system, a dispensing head for dispensing liquid and connected with a transfer tube to the valve system, a dispensing pump connected to the valve system, a first inlet port for conducting rinse liquid to the valve system, and a second inlet port for conducting rinse gas to the valve system. The device includes control equipment for operating the valve system so that the flow via the transfer tube towards the dispensing head includes both the rinse liquid and the rinse gas. The rinse gas is capable of collecting gas bubbles formed on the inner walls of the transfer tube to larger amounts of gas. Thus, the rinse gas facilitates the removal of the gas bubbles with the aid of the rinse liquid.
