Abstract
Abstract A process and apparatus are disclosed in which powdered material is compacted to a predetermined density by suction applied to the bottom of a supply trough and then doctored to a predetermined level. A measured charge of the compacted and leveled powder is then taken up by inserting a filling gun into the powdered material. The filling gun and the container to be filled with the measured charge are then brought into registration and the measured charge is delivered to the container. Powdered material is added to the supply trough as required so that the required level can be maintained. When desired, the powder can be agitated as by means of an air stream supplied as a counter flow through the bottom of the supply trough. The measured charge can also be further compacted before being discharged by advancing the piston of the filling gun while the open end of the gun is against an obstruction.

Claim 4
Dependent Claim
121 words
Apparatus for measuring and dispensing a predetermined volume of powdered material, comprising a supply container, means for delivering powdered material to said supply container, means including an open ended measuring member defining a predetermined volume, means for sequentially a. applying suction to the powdered material in said supply container to compact said powdered material to a predetermined density, b. maintaining the depth of said compacted powder material in said supply container at a predetermined level, and c. inserting said measuring member into said compacted and leveled powdered material to a predetermined depth and for charging asid measuring member with a predetermined volume of said compacted material, and means for discharging said predetermined volume of said compacted material from said measuring member.
Claim 5
Dependent Claim
131 words
Means for measuring and dispensing powdered materials comprising: a supply container for holding powdered material; means for compacting said powdered material to a predetermined density in said supply container comprising a porous filter mounted in said supply container for supporting powdered material on the upwardly presented surface of said filter in said supply container, and means for applying suction to the undersurface of said filter to compact said powdered material to a predetermined density; means for controlling the level of said powdered material in said supply container; at least one measuring gun comprising an elongated hollow member; means for inserting said gun into said material in said supply container a predetermined distance into said supply container to charge said gun; and means for ejecting said compacted powder material from said gun.
Claim 6
Dependent Claim
131 words
Means for measuring and dispensing powdered materials comprising: a supply container for holding powdered material; means for compacting said powdered material to a predetermined density in said supply container comprising a porous filter mounted in said supply container for supporting powdered material on the upwardly presented surface of said filter in said supply container, and means for applying suction to the undersurface of said filter to compact said powdered material to a predetermined density; means for controlling the level of said powdered material in said supply container; at least one measuring gun comprising an elongated hollow member; means for inserting said gun into said material in said supply container a predetermined distance into said supply container to charge said gun; and means for ejecting said compacted powder material from said gun.
Claim 7
Dependent Claim
56 words
Apparatus as in claim 3 comprising means for moving the powdered material in said supply container, so that portions of said powdered material pass successively through a first area and a second area, means in said first area to aerate and agitate the powdered material, and said means for applying suction being in said second area
Claim 8
Dependent Claim
52 words
Apparatus as in claim 4 wherein said supply container is a rotatable trough, and further comprising a rotatable turret, a plurality of said measuring guns being mounted on said turret, means for rotating said turret so that said measuring guns extend said trough during a portion of each rotation of said turret.
