摘要:
This invention is directed to an apparatus for filling powder which comprises introducing a predetermined amount of powder into each of the receiving holes formed at the peripheral edge portion of a rotary disk from a powder hopper, intermittently rotating the rotary disk, and discharging and filling the powder accommodated in each of the receiving holes into a powder container positioned therebelow when each of the receiving holes reaches a discharging and filling portion. The rotational axis (C) of the rotary disk (1) is inclined. The center axis of each of the receiving holes (8) is arranged on an imaginary conical surface (12) having this rotational axis (C) as its center axis and an apex angle (.theta.) of 60.degree. to 120.degree.. The powder hopper (6) is disposed on the lateral side portion of an opening (8a) of the receiving hole (8) at a vacuum sucking portion (9) and a boss portion (28) supporting the rotational axis (34) of the agitator (7) is arranged above the powder hopper (6). This apparatus is suitable for being used at the step of filling various kinds of powder, especially injection or the like powdered pharmaceutical product requiring the accuracy of the amount to be filled and the non-contamination of foreign matters, into vials or the like containers.
摘要:
The present application discloses an improved filter assembly used in a dry powder filling machine in which the bottom of the cylindrical measuring cavity for the powder being measured is formed by the improved filter assembly having a cup shaped recess wherein the floor of the recess contains evenly spaced and relatively small apertures. The aperture-containing floor is backed by a screen which allows vacuum to be applied to draw powder into the cavity but which prevents passage of the powder through the screen while the cavity is being filled. Application of gas pressure to the underside of the floor of the cavity expels the measured powder into a container as a discrete slug with relatively little separation.

A filling machine for small containers comprises a main hopper which feeds powder to a secondary hopper located above a rotatable dosing head provided with chambers for receiving the powder from the secondary hopper and discharging the powder into individual containers successively displaced below this head. Between the secondary hopper and the rotating head is provided a yieldable intermediate body having a curved surface confronting the curved surface of the head and an opening adapted to communicate between the chamber of the head and the secondary hopper. One of these surfaces is formed with a pair of grooves on each side of the opening and between each pair of grooves with a recess to which compressed air is admitted with the air being discharged through ports in the grooves so that a hermetic seal is provided between the recesses. Pins can space the intermediate body form the head when compressed air is not supplied to the seal.

A high productivity packaging apparatus and method are based on utilization of a container and a plurality of circular arranged valves which are connected to and rotate with the container. During rotation each valve draws a unit of material to be packaged from the container at one station, holds the unit of material in the valve during continuing rotation and then discharges the unit of material at a discharge station to which empty containers are fed successively in synchronism with successive valves being discharged.
摘要:
Apparatus useful for feeding a particulate starter material comprising nutrient and bacteria to a mixing tank, for solubilizing the starter material inside the mixing tank, for promoting growth of the bacteria and for discharging an aqueous slurry comprising the bacteria from the mixing tank. The apparatus preferably has a gravity-flow feeder and discharge port, does not require a pump, and comprises disposable parts.

A device for feeding charges of non-homogeneous infusion material to a packaging machine includes a metering device for the charges and transfer system for the charges which is positioned downstream of the metering device and which feeds the charges to the packaging machine. The transfer system includes a charge adjustment system equipped with a drum which is rotatable about its own axis A and at least one roller which is rotatable about its own axis B and which is located upstream of the drum. The drum includes a chamber for receiving the charge from the roller. During adjustment of the charge, the chamber is variable between a maximum value coinciding with the receiving step and a minimum value when the charge has been adjusted.
摘要:
A difference between a first expected required polish time for a first substrate and a second expected required polish time for a second substrate is determined using a first pre-polish thickness and a second pre-polish thickness measured at an in-line metrology station. A duration of an initial period is determined based on the difference between the first expected required polish time and the second expected required polish time. For the initial period at a beginning of a polishing operation, no pressure is applied to whichever of the first substrate and the second substrate has a lesser expected required polish time while simultaneously pressure is applied to whichever of the first substrate and the second substrate has a greater expected required polish time. After the initial period, pressure is applied to both the first substrate and the second substrate.
