Patent number: 11772954Abstract: A carbonated water dispenser comprises a carbonator with a water inlet and a carbonated water outlet. A backflow preventer module is fluidically coupled to the water inlet and comprises a check valve and a thermal mass flow meter. The thermal mass flow meter is configured to communicate a first signal based on a measured amount of heat transferred from a heater to a temperature sensor by a flow of a fluid through the backflow preventer module. A shut-off valve is fluidically coupled between the carbonated water outlet and a nozzle. The shut-off valve is configured to allow or prevent fluid flow from the carbonated water outlet to the nozzle base on a control signal. A controller is configured to detect a backflow condition based on the first signal and generate the control signal to configure the shut-off valve to prevent dispensing carbonated water upon detection of the backflow condition.Type: GrantFiled: March 24, 2023Date of Patent: October 3, 2023Assignee: The Coca-Cola CompanyInventors: James Dalberg, Jevawn Sebastian Roberts, Brian B.

Patent number: 11644353Abstract: A flow control module with a thermal mass flow meter is provided. The thermal mass flow meter facilitates measuring both a flow rate and a temperature of a fluid passing through the flow control module. Fluids may experience different flow characteristics at different temperature ranges. The flow control module includes a proportional control valve for selectively adjusting the flow rate of the fluid passing through the flow control module. Upon detecting that the temperature of the fluid is outside of a temperature range for the fluid, a controller is configured to load a different set of calibration parameters for controlling the operation of the proportional control valve to accommodate the different flow characteristics of the fluid at that temperature. Additionally, the controller is configured to detect bubbles using the thermal mass flow meter based upon the difference in thermal conductivity of gasses and liquids.Type: GrantFiled: September 6, 2019Date of Patent: May 9, 2023Assignee: THE COCA-COLA COMPANYInventors: James Dalberg, Jevawn Sebastian Roberts, Brian B.

Patent number: 9316218Abstract: One or more techniques and/or systems are disclosed for increasing compressed air efficiency in a pump that utilizes an air efficiency device in order to optimize the amount of a compressed air in the pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self-adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings are achieved by minimizing the amount of required compressed air.Type: GrantFiled: August 8, 2014Date of Patent: April 19, 2016Assignee: Warren Rupp, Inc.Inventors: Mark D. McCourt, Haihong Zhu, Michael Brace Orndorff, Jevawn Sebastian Roberts, Charles Randolph Abbott
