Publication number: 20200386327Abstract: A method of controlling the flow of different flow paths of fluid is provided. The method includes rotating a valve to a first position, receiving a first concentrate in the first position, discharging the first concentrate through one of two outlets, rotating the valve to a second position, receiving a second concentrate in the second position, and discharging the second concentrate through one of the two outlets.Type: ApplicationFiled: June 19, 2020Publication date: December 10, 2020Inventors: Steven E. Schiller, James H. Lohr, Paul J. Larson

Patent number: 10690254Abstract: A selector valve assembly for use in conjunction with an eductor dispensing system which reduces the incidence of product carry-over when the valve is moved from one position to another. The selector valve assembly also reduces the incidence of improper dispensing. In a preferred manner, the selector valve assembly has a single valve member and accommodates four product inlet lines for selectively passing chemical concentrate to two eductors. The selector valve assembly is composed of a minimum of ports, thereby reducing maintenance and cost.Type: GrantFiled: August 15, 2017Date of Patent: June 23, 2020Assignee: Diversey, Inc.Inventors: Steven E. Schiller, James H. Lohr, Paul J. Larson

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. Johnson & Son, Inc.Inventors: Jeremy F. Knopow, Steven Merrill Harrington, Andrew L. Banka, Paul J. Larson, Ernst K. Reiter

Patent number: 8636031Abstract: A selector valve assembly controlling the flow of different flow paths of fluid. The assembly includes a body member having a compartment with an end wall, an outlet passage in the end wall, two ports connected to the body member and communicating with the outlet passage in the end wall, and two passages communicating with the compartment. A rotatable member is sealable positioned in the compartment and has a side wall and an end wall. A first passageway extends a distance into the rotatable member from the end wall thereof and a second passageway extends through the side wall thereof and communicates with the first passageway. Rotation of the rotatable member selectively orients the second passageway with each of the two passages to cause liquid in the two passages to pass to the first and second passageways and subsequently to the outlet passage and at least one of the ports.Type: GrantFiled: May 29, 2012Date of Patent: January 28, 2014Assignee: Diversey, Inc.Inventors: Steven E. Schiller, James H. Lohr, Paul J. Larson
