Patent number: 10603620Abstract: A driving system for a reversing blower adsorption based air separation unit is configured to not only drive the reversing blower cyclically in a forward and in a reverse direction, but also to allow the reversing blower to coast during a portion of its operating cycle. While coasting, a pressure differential across the blower acts alone to switch the reversing blower between a forward and a reverse direction of operation. Less power is thus required. When coasting, the blower can also be configured to output power such as the drive motor functioning as an electric generator or by having a mechanical power input be driven by the blower for power generation and/or energy storage. Such a system beneficially utilizes the energy associated with the pressure differential across the blower for energy harvesting and to further accelerate cycle times for the reversing blower adsorption based air separation unit.Type: GrantFiled: November 13, 2017Date of Patent: March 31, 2020Assignee: Pacific Consolidated Industries, LLCInventors: Mark Baker, Jason Burns, William K.

Patent number: 10478768Abstract: An exemplary single bed reversing blower adsorption based air separation unit is configured to follow the O2 load placed thereon by adjusting flow rates therethrough and power consumption. At least one and preferably multiple pressure sensors sense O2 pressure within an O2 storage region downstream of an adsorber vessel. These sensed pressures are utilized to generate control signals controlling flow rates at locations upstream of the compressor, such as at a reversible blower and an output compressor. Control loops for the blower and the compressor are independent of each other and have different time constants. Effective following of the O2 load is thus achieved without driving the air separation unit into operational conditions outside of design and also maintaining optimal power consumption for the O2 produced, such that efficiency is maintained over a large turndown ratio.Type: GrantFiled: October 10, 2017Date of Patent: November 19, 2019Assignee: Pacific Consolidated Industries, LLCInventors: Javier Lopez, Jason Burns, William K.

Patent number: 9610532Abstract: A multi-unit system combines multiple single bed reversing blower vacuum swing adsorption air separation units together. The units feed a common O2 supply such as a system buffer tank. Demand is monitored and a number of individual units are brought online sufficient to meet demand. If demand exceeds supply, a further unit is brought online. If demand drops below supply by an amount greater than output of a single unit, then a longest operating unit is taken offline. The multi-unit system thus meets demand through utilization of multiple separate units in a highly redundant and highly reliable and scalable fashion.Type: GrantFiled: December 16, 2015Date of Patent: April 4, 2017Assignee: Pacific Consolidated Industries, Inc.Inventors: Robert Wimmer, Jason Burns, William K.

Publication number: 20160184760Abstract: A single bed reversing blower vacuum swing adsorption air separation unit includes a purge recovery tank. This purge recovery tank is joined to an O2 supply line downstream of the adsorber vessel or directly to the adsorber vessel opposite an inlet thereof. The purge recovery tank collects a purging charge of mostly O2 gas towards the end of a production phase for the air separation unit. This purging charge is held by the purge recovery tank while the reversing blower reverses and the material within the adsorber vessel is recharged. Around the time that the reversible blower is re-reversed to return to a production phase, the purge recovery tank is opened to allow mostly O2 gas from the purge tank to quickly flow back into the adsorber vessel which has a vacuum drawn thereon, to allow the air separation unit to quickly return to its production phase.Type: ApplicationFiled: December 16, 2015Publication date: June 30, 2016Inventors: Michael Bottum, Jason Burns, William K.

Patent number: 5802454Abstract: A network of interconnected, remotely distributed, location and messaging systems. Each of the remotely distributed location and messaging systems can be dynamically configured to use different frequencies that are assigned to the regions. Each of the remotely distributed location and messaging systems performs location requests for specified subscriber unit using one or more radio frequency transmitting sites and a plurality of radio frequency receiving sites. The location request is initiated by identifying a particular one of the location and messaging systems having a coverage area for the specified subscriber unit. The location request is routed to the identified location and messaging systems, and a unique paging message is transmitted to the subscriber unit. A response is received from the subscriber unit, and forwarded to a processor coupled to the identified location and messaging system.Type: GrantFiled: December 15, 1995Date of Patent: September 1, 1998Assignee: Teletrac, Inc.Inventors: William K.
