Title: System for energy recovery in a vacuum pressure swing adsorption apparatus
Inventor: SINICROPI MICHAEL JOHN
IPC: B01D53/04
Filed: 1998-01-27
Granted: 2002-01-01
Abstract: A VPSA apparatus includes a first adsorbent bed and a second adsorbent bed, a feed blower for providing a flow of a gas mixture at about atmospheric pressure to the beds, and a vacuum blower for removing a flow of gas therefrom and venting the gas to a space at atmospheric pressure. The VPSA process causes the first adsorbent bed to be poised for evacuation by the vacuum blower and concurrently, the second adsorbent bed is under vacuum conditions and is poised for pressurization by the feed blower.  A single motor is coupled by a common shaft to both the feed blower and the vacuum blower and operates both.  A conduit/valve arrangement is operative during at least a portion of a process time when the adsorbent beds are in pressurizing/evacuation states, respectively, to couple the feed blower to the second adsorbent bed when at vacuum and for concurrently coupling the vacuum blower to the first adsorbent bed which is to be evacuated.  The feed blower is thereby caused to operate in a gas expansion mode and imparts expansion energy, via the common shaft, to the vacuum blower.  During idling conditions, a valve-conduit system is controlled to enable significant reductions in pressure rise across the feed and vacuum blowers.

Granted: 2006-01-10
Abstract: Pressure vessels having end closures for sealing at least one open end are constructed so as to provide full-bore access to a generally tubular shell portion wherein one or more filter cartridges will be disposed.  A sealing ring (45) of rectangular cross section is seated in a groove provided in the tubular shell (15) at a location axially inward of a cylindrical surface region wherein a central annular groove is provided. A closure head (39) fits within this annular surface and includes a shoulder (73) which prevents insertion past the sealing ring (45). The head may be a 2-piece construction wherein a flanged and dished element having an inward facing convex surface of oblate spheroidal shape protrudes through the interior of the sealing ring and mates with a securing plate (41) having an annular notch in the periphery of its outer face that aligns with the groove in the tubular shell to create a pocket designed to receive a helical locking ring (79) in the form of a spring-like band of at least two revolutions that cannot be inadvertently removed when the vessel is pressurized. A bell-end configuration for the tubular shell is efficiently created from filament-reinforced polymeric resin through the use of a sacrificial insert that not only creates the seat for the sealing ring but also provides space to accommodate side flow fluid connections.

Abstract: A composition is disclosed for application to a plant that comprises a glyphosate or a herbicidal derivative thereof, an aqueous diluent, and a first excipient substance that is amphiphilic. The weight/weight ratio of the first excipient substance to the glyphosate or herbicidal derivative thereof is between about 1:3 and about 1:100. The aqueous composition forms anisotropic aggregates on a wax layer, and the presence of the anisotropic aggregates can be detected by a test described herein.  Compositions of the present invention, when applied to plants, provide enhanced biological activity per unit amount of glyphosate or herbicidal derivative thereof, as compared to otherwise similar compositions containing surfactants that do not form anisotropic aggregates.  Without being bound by theory, it is presently believed that this enhanced biological activity results from the formation or enlargement of hydrophilic channels through the epicuticular wax of the plant.
