Abstract: A can opening system and method for removing the contents of a plurality of cans. The can opening system includes a housing adapted to receive a can and shield an operator from equipment within the housing, a top clamping assembly within the housing adapted to clamp onto a top edge of the can, a bottom clamping assembly within the housing configured to clamp against a lower side of the can, a punch cutter above the top and bottom clamping assemblies for extracting and retaining a lid of the can, and a punch tip within the housing adapted to puncture a bottom of the can and dispense the remaining contents of the can. The can opening system is adapted to remove up to about 90% of contents of a can for materials having a viscosity up to about 250,000 Centipoise.

Abstract: A clip for holding the lever of a gasoline pump dispensing handle in open gasoline dispensing position made from a single flat plate of uniform thickness having a rear shank about 11/2 inches in length with a pair of identical arms extending about 11/2 inches from the opposite ends of the shank and forming between said arms an angle of approximately 40 degrees. A serrated row of similar flat-topped teeth lies along the inner edge of each arm with the flat tops of each serrated row of teeth lying in a common plane and the two planes containing said flat tops intersecting each other at an angle of approximately 40 degrees. Preferably each row contains six flat-topped teeth.

Abstract: A reverse blow-back dust collector utilizes a simplified top removal support arrangement for suspending bag, cage and nozzle assemblies from a tube sheet having plain mounting openings therein. The top removal support includes a collar spot welded to the cage and disposed in force fit engagement with a top fold region of the bag which contains an expansion clamping ring assembly having spaced beads which interlock the bag in sealed relation in its corresponding tube sheet opening. The support also includes a flange which overlies and seats on the upper bead for transmitting cage loads thru the support to the top side of the tube sheet. Ease of assembly and removal affords improved installation and servicing operations.

Abstract: A bottom removal type of filter bag assembly for reverse blow-back type dust collectors is mounted on a permanent support structure that is welded in place to a depending integral collar portion of the dust collector tube sheet. The permanent support has a stepped diameter wall structure having a reduced upper end portion for force fit insertion in the tube sheet collar and having an intermediate shoulder to engage axially against the end of the collar.

Abstract: Pipeline capsules, pigs, or other solid objects bypass a pipeline pump station via a bypass system that avoids cycling of the primary fluid flow. The fluid is removed from the main pipeline through perforations in the pipeline wall, transported through the pump and reinjected into the main pipeline downstream from the fluid removal point. Two valves are located in the main pipeline between the fluid removal point and the fluid reinjection point. The first valve is opened in response to the detection of the incoming solid object, allowing it to pass through the valve. The first valve is then closed and the second valve opened to allow the solid object to pass through the second valve and re-enter the main fluid stream.
