A device is described for dispensing and dosing materials in powdery, liquid, pasty or creamy form, comprising a plurality of containers (1), a plurality of pumps (2), a dispensing apparatus (3), two pump mechanisms comprising a pump screw (4), (5), the delivery apparatus (3) common to all pumps (2) comprising positioning means (11) of the delivery apparatus (3) with respect to each of the pumps (2) and means for actuating (12), (13) the mechanisms of each of the pumps (2).

There is described a device for dispensing a drug or medicament in pellet form. The device includes a cartridge including a chamber for containing a plurality of pellets and a screw pump, wherein the screw pump is configured to receive pellets from the chamber and, upon rotation of the screw pump, transport the pellets from the chamber to be dispensed from the device via the screw pump. The device further includes a rotating member extending through the cartridge and configured to rotate the screw pump so as to dispense pellets therefrom. The cartridge further includes a tapered portion configured to guide pellets contained within the chamber into the screw pump for dispensing from the device via the screw pump as aforesaid. The screw pump is located outside of the tapered portion of the cartridge.

A portable grout device is provided. The device includes a grout hopper, a cylindrical tube portion connected to and operable to receive grout from the grout hopper, and a drive shaft and auger assembly within the cylindrical tube portion. The drive shaft and auger assembly includes a central shaft and a helical auger screw operable to push the grout out of an end of the cylindrical tube portion.

The disclosure relates to a metering apparatus for free-flowing material and to a method for operating such a metering apparatus. The metering apparatus has a metering duct having a closed cross section and further has a rotary drive (M). The metering duct is wound in the form of a screw with a vertical longitudinal axis. The free-flowing material is fed to the metering duct. The metering duct is set via the rotary drive (M) in an oscillating rotary motion about its longitudinal axis with individual rotary strokes, wherein, with each rotary stroke, a partial quantity of the free-flowing material falls out of a lower discharge opening of the metering duct.

The invention relates to a method and to an arrangement for feeding fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2). The invention relates also to a controlling means for controlling feeding of fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2) in an arrangement for feeding fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2). The invention relates also to controlling means for controlling feeding of fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2) in an arrangement for feeding fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2) and to a computer program product.

A method of machine condition monitoring, wherein at least one measured and/or calculated machine parameter is monitored during the operation of a machine, and wherein a change in the machine condition, particularly a critical operating state of the machine, is deduced when at least one monitored machine parameter reaches a limit value, and wherein at least one monitored machine parameter is monitored depending on at least one other machine parameter in defined operating point ranges of the machine, wherein a change in machine condition is deduced when at least one monitored machine parameter within a defined operating point range reaches at least one limit value individual to the operating point range.

The invention relates to a method for setting a cell concentration and/or a particle concentration in a dispensing device by means of which a liquid sample can be discharged, wherein the cell concentration and/or the particle concentration is ascertained in one region of the dispensing device, and the cell concentration and/or particle concentration that has been ascertained is compared with a target value, and a force exerted on one cell and/or one particle is adjusted based on the result of the comparison.

A device for transferring a toxic substance from a dispensing vessel to at least one receiving vessel comprising: (i) a receiving portion arranged to receive a dispensing vessel containing a toxic substance; and (ii) a transfer apparatus having a first infusion line adapted for fluid communication with the dispensing vessel to transfer a carrier fluid into said vessel and a second infusion line having one end adapted for fluid communication to withdraw and transfer the carrier fluid and the toxic substance from the dispensing vessel and the other end of the second infusion line arranged to connect with the at least one receiving vessel.

Fluid transport approaches are described that operate without the need for precise displacement of an actuator and with little or no sensing in the flow path. In certain implementations, a gas phase in a fluid reservoir is compressed by a pressure source such that releasing the pressure, such as by opening a valve to an intermediary conduit, displaces fluid to the intermediary chamber. Closing that fluid path and opening a different fluid path to a chamber at ambient temperature causes the fluid to be displaced to the chamber.

Pacifier devices with internal reservoirs and metering units are described. The metering units provide single dosages of an internal supplement material during a fixed period of time. For example, embodiments of pacifier devices can be utilized to provide supplemental nutrition paste or gel to undernourished infants with metered dosages as appropriate to the supplement.
