Patent number: 11986690Abstract: The method of maintaining a first flow rate through a first valve in a fluid delivery system, the fluid delivery system including a and a plurality of fluid valves in fluid communication with the pump, and a controller controlling the pressure generated by the pump and the position of the plurality of valves. The method includes providing the first flow rate of a fluid pressurized by the pump through the first valve, receiving a request for a second flow rate of the fluid through a second valve, determining a predicted effect on the first flow rate based on the request, adjusting at least one of the position of the first valve and the pressure generated by the pump to maintain the first flow rate based on the predicted effect, and adjusting the position of the second valve to provide the second flow rate of the fluid through the second valve.Type: GrantFiled: June 30, 2022Date of Patent: May 21, 2024Assignee: Elkhart Brass Manufacturing Company, Inc.Inventors: Eric N. Combs, Donald E. Sjolin, Frederic J. Einstein, Kevin McGuire, Lee R. Jones, John E. McLoughlin, Neocles G. Athanasiades, Kiam Meng Toh, Kyle A. Stoops

Patent number: 9399151Abstract: A control system for a fire fighting device is provided. The control system may include a controller configured to operably connect over a network to a first valve controller controlling a status of a first valve in response to an input from the controller, a second valve controlling a status of a second valve in response to an input from the controller, and a governor operably controlling a power source in response to an input from the controller. The control system may further comprise a touchscreen display operably connected to the controller, the display configured to display the status of the first and second valves and configured to receive an input from a user, wherein controller generates a manipulatable icon displayed on the touchscreen display, a manipulation of the icon generating the input from the controller to the first valve controller.Type: GrantFiled: August 16, 2012Date of Patent: July 26, 2016Assignees: Elkhart Brass Manufacturing Company, Inc., Fire Research Corp.Inventors: Eric N. Combs, Donald E. Sjolin, Fred Einstein, Kevin McGuire, Lee R. Jones, John E. McLoughlin, Neocles G. Athanasiades, Kiam Meng Toh, Kyle A. Stoops

Patent number: 8820424Abstract: A fire fighting nozzle includes a nozzle body with an inlet, an outlet, and a passageway extending from the inlet to the outlet. A stem is located in the passageway about which fluid flows when fluid is flowing through the passageway. And, a projecting body projects outwardly from the nozzle body away from the stem, which at least partially fills the space beyond the nozzle outlet where water exits the nozzle assembly.Type: GrantFiled: July 7, 2009Date of Patent: September 2, 2014Assignee: Elkhart Brass Manufacturing Company, Inc.Inventors: Todd Brian Lozier, Donald E. Sjolin

Publication number: 20100319479Abstract: A rotary control for controlling an electromechanical device includes a body adapted to mount to a surface and an outer ring pivotally connected to the body. The outer ring has an outer perimeter with a generally undulating profile having peaks and valleys, and has an outer face with a plurality of protrusions extending from the outer face, with the protrusions substantially corresponding with the peaks. The rotary control also includes a sensor adapted to sense rotation of the outer ring and output a signal corresponding to the rotation, and a control adapted to receive the signal and control the electromechanical device in response to the rotation of the outer ring.Type: ApplicationFiled: June 3, 2010Publication date: December 23, 2010Applicant: ELKHART BRASS MANUFACTURING COMPANY, INC.Inventors: Donald E. Sjolin, Eric Nathaniel Combs, Todd Brian Lozier, John E. McLoughlin, Neocles G. Athanasiades, Toh K. Meng
