Filed:

Jul 18, 1989

Appl. No.:

7/381447

Richard K. Lowery - Warminster PA

Assignee:

National Safety Associates, Inc. - Memphis TN

International Classification:

B01D 2708

US Classification:

210232

Abstract:

A method for making a low pressure cartridge for liquid filtration, particularly of minerals from drinking water, comprises locating a pair of substantially identical end cap members telescopically on opposing ends of a tubular member. The end cap members are coupled to the tubular member mechanically by interference between four circumferential rings raised from an inner surface of each of the end caps and like numbers of circumferential grooves on a facing surface of the tubular member. O-rings between the telescoped members provide further fluid sealing and increased mechanical coupling, if desired. Different axial spacing between different adjoining pairs of rings assure axial alignment of the end caps with the tubular member during assembly.

Abstract:

An article bagging unit particularly useful in bagging ice cubes. A bag, positioned to receive articles to be bagged, is partially opened by an air blower and then fully opened by two pairs of fingers. Each of the fingers is movable into and out from a bag. After the fingers are moved into a partially open bag, one pair of fingers moves away from the other pair of fingers and spreads the front and the back of the bag. Next, a prescribed quantity of articles is delivered to the bag. Then the fingers are retracted from the bag and a pair of heat-sealing members converge to clamp the tops of the front and the back of the bag to seal the bag.
