Patent number: 9291391Abstract: Methods and systems are disclosed for drying a material or, more generally, flash evaporating a target substance having a vapor pressure threshold. The methods and systems include a conveyor conduit that receives material and within which a pressure is established that is greater than the vapor pressure threshold of the target substance. The material moves through the conveyor and is expelled into a pressure drop zone created by one or more venturi nozzles. The pressure in the pressure drop zone is far less than the vapor pressure threshold of the target substance. As the material encounters the pressure drop zone, the targeted substance in the material experiences a rapid and extreme pressure drop and simultaneously a rapid temperature increase. This causes the target substance in the material to flash evaporate virtually immediately. The resulting vapor is separated from the remaining material and the now dry material is collected for further processing or use.Type: GrantFiled: April 18, 2014Date of Patent: March 22, 2016Assignee: Flash Rockwell Technologies, LLCInventor: John Hogan

Patent number: 8695156Abstract: The aero-acoustic duster invention disclosed herein provides for high particle removal rate from surfaces with low energy expenditure relative to competing vacuum-based devices. The device removes particulate matter from a surface using a two-step process: 1. Acoustic radiation is used to break the adhesive bonds between dust and the surface, forcing particles into a mode where they continuously bounce up and down on the surface; and, 2. A bounded vortex is generated over the surface, with suction in the vortex center and jets for blowing air along the periphery. The jets are tilted in the tangential direction to induce vortex motion within the suction region. The vortex is said to be bounded because streamlines originating in the downward jets are entrained back into the central vortex.Type: GrantFiled: February 9, 2011Date of Patent: April 15, 2014Inventors: Jeffrey S. Marshall, Di Chen, Nicholas Mario Vachon, Darren Hitt, Junru Wu

Patent number: 8689810Abstract: A device installation and methods for extracting dust during the transfer of pulverulent products from a first container to a second container, the combination of the first container and of the second container forming, with the dust extraction device, a closed containment volume with connection between the two containers. A hollow connector with a side wall between its two ends defines an external wall and an internal wall so that the connector is pierced with several inlet pipes connected to hoses fed with a stream of pressurized fluid and also pierced with at least one fluid discharge pipe. The pipes projecting from said external wall of the connectors and opening onto the internal wall via orifices allows fluid to be introduced, the orifices being oriented relative to one another in such a way as to cause the fluid to flow in a cyclone within the connector, carrying with it any pulverulent product that remains on the internal wall and/or upstream and/or downstream of said connector.Type: GrantFiled: June 22, 2009Date of Patent: April 8, 2014Assignee: Changexplorer ProductionInventor: Francois Rolin

Patent number: 8684022Abstract: A device to clear a blockage from an HVACR condensate drain line. A piston connected to a rod with a handle is inserted directly into the distal or outlet end of a condensate drain pipe and then rapidly withdrawn to create a vacuum or suction within the drain line. When sufficient suction pressure is created, it will dislodge a blockage in the drain line. Typically the piston has a proximal end with a diameter slightly greater than the inside diameter of the condensate drain pipe. Upon removal of the device from the drain pipe, the proximal end is caused to expand to its full diameter, creating an airtight and fluid tight seal with the inner diameter of the drain pipe, allowing for the creation of negative pressure and/or suction upstream to dislodge the blockage.Type: GrantFiled: January 29, 2013Date of Patent: April 1, 2014Assignee: Good Day Tools, LLCInventor: Richard Dean McFarland

Patent number: 8661608Abstract: Handheld portable devices for dislodging and capturing particulate matter that has accumulated on various surfaces or structures are provided. The devices create opposing airflows that can intimately interface with each other during use. A vacuum airflow is drawn into the device, defining a vacuum affected zone upon the surface being cleaned. A high pressure airflow is emitted that penetrates through or passes adjacent to the opposing vacuum airflow and contacts the surface being cleaned, dislodging particulate matter therefrom. The high pressure airflow can be emitted from multiple nozzles as a series of airflow bursts that discretely contact the surface being cleaned. The configuration of each nozzle, as well as the overall arrangement and positions of all the nozzles together, are selected to impart the desired particulate matter dislodging characteristics to the device.Type: GrantFiled: July 9, 2008Date of Patent: March 4, 2014Assignee: S.C. Johnson & Son, Inc.Inventors: Jeremy F. Knopow, Steven Merrill Harrington, Andrew L. Banka

Patent number: 8661609Abstract: Portable devices for dislodging and/or capturing particulate matter that has accumulated on various surfaces or structures are provided. The devices include a body segment and a nose segment extending away therefrom. A high-pressure assembly generates a high-pressure airflow that is directed to a nozzle assembly in the nose segment. From the nozzle assembly, the high-pressure airflow can be emitted from multiple nozzles as a series of airflow bursts that discretely contact the surface from which the particulate matter is being dislodged. The configuration of each nozzle, as well as the overall arrangement and positions of all the nozzles together, is selected to impart the desired particulate matter dislodging characteristics to the device, and the device may incorporate a vacuum airflow to remove the particulate matter after such matter has been dislodged.Type: GrantFiled: December 3, 2009Date of Patent: March 4, 2014Assignee: S.C.
