Abstract
A vacuum fill system for deaerating flowable material includes a cylindrical container partitioned into a plurality of chambers which rotate sequentially and which are connected to a vacuum pump for establishing a vacuum when filled with flowable material. The flowable material deaerates and compacts when atmospheric pressure is subsequently restored.
Claims12
A vacuum fill system for deaerating flowable material comprising:
- means defining a plurality of chambers;
- enclosed, airtight housing means surrounding chamber-defining means and defining a plurality of zones equal in number to the plurality of chambers;
- means for sequentially aligning each of the chambers with each of the zones of the housing means;
- means for filling each chamber with flowable material when the chamber is aligned with one of the zones;
- means for creating a vacuum in each chamber when the chamber is aligned with the next adjacent zone for deaerating the flowable material;
- and
- means for thereafter returning the pressure in each chamber to atmospheric pressure substantially instantaneously for compacting the deaerated flowable material.

A vacuum fill system for deaerating flowable material comprising:
- an enclosed, airtight housing defining four zones of equal size;
- means mounted within the housing and comprising four chambers of equal size which rotate about an axis;
- a geneva mechanism for sequentially aligning each of the four chambers with each of the four zones;
- means for filling each chamber with flowable material when the chamber is aligned with a predetermined one of the zones;
- at least one vacuum pump for creating a vacuum in the filled chamber when the filled chamber is subsequently aligned with the next adjacent zone for deaerating the flowable material within the filled chamber;
- and
- the interior of each chamber being substantially instantaneously returned to atmospheric pressure when the chamber is aligned with the next adjacent zone to compact the deaerated flowable material therein.

A vacuum fill system for deaerating flowable material comprising:
- enclosed, airtight housing defining four zones of equal size;
- a four-walled partition mounted within the housing and comprising four chambers of equal size which rotate about a horizontal axis;
- a geneva mechanism for sequentially aligning each of the four chambers with each of the four zones;
- means for filling each chamber with flowable material when the chamber is aligned with a predetermined one of the zones;
- at least one vacuum pump connected t the housing for creating a vacuum in the filled chamber when the chamber is aligned with the n ext adjacent zone for deaerating the flowable material within the chamber;
- at least one vacuum line connecting the housing and the vacuum pump;
- means for returning the pressure in the chamber filled with deaerated flowable material to atmospheric pressure substantially instantaneously when the chamber is aligned with the next adjacent zone to compact the deaerated flowable material therein.

A vacuum fill system for deaerating flowable material comprising:
- enclosed, airtight housing defining four zones of equal size;
- at least four chambers of equal size mounted within the hollow container which rotate about a vertical axis;
- a geneva mechanism for sequentially aligning each of the four chambers with each of the four zones;
- means for filling each chamber with flowable material;
- at least one vacuum pump connected to the housing for creating a vacuum in each chamber when the chamber is aligned with the next adjacent zone and thereby deaerating the flowable material within the chamber;
- at least one vacuum line connecting the housing and the vacuum pump;
- and
- the interior of each chamber being substantially instantaneously returned to atmospheric pressure when the chamber is aligned with the next adjacent zone to compact the deaerated flowable material therein.
