  • Patent number: 8459290
    Abstract: A material gas concentration control system for keeping a concentration of a material gas in a mixed gas constant comprising a tank to accommodate the material, an inlet line to input a carrier gas for evaporating the accommodated material into the tank, and an outlet line to output the mixed gas consisting of the material gas evaporated in the tank and the carrier gas, and further comprising a first valve arranged in the inlet line, a concentration measuring part that measures the concentration of the material gas in the mixed gas, and a concentration control part that controls an open degree of the first valve so as to make the measured concentration of the material gas measured by the concentration measuring part become the previously determined set concentration.

  • Patent number: 8459291
    Abstract: To prevent loss of control of a pressure of a source gas within a movable range of a control valve, a source gas concentration control system is provided. The system may include a first valve that is provided on an outlet line, a concentration measurement part that measures a concentration of the source gas in mixed gas, and a concentration control part that controls a stroke of the first valve such that the measured concentration of the source gas becomes equal to a predetermined concentration setting. The measured concentration may be measured in the concentration measurement part. The system may further include a temperature controller that controls a temperature inside the tank to meet a temperature setting, and a temperature setting part that sets the temperature setting of the temperature controller.

  • Patent number: 8443827
    Abstract: A controlling device for hydraulic consumers (10, 12) has one controlling valve (18) for controlling a supply pipeline (TReg) for the hydraulic consumer (10, 12) and a tank return pipeline (TRO). Because the control valve (18) is connected to an additional supply pipeline (TR) and constructed as a priority valve, the supply pipeline (TReg) receives priority preference of a fluid supply system over the priority of the tank return pipeline (TRO). A sensor circuit is realized which checks whether, in accordance with the load situation at the hydraulic consumer (10, 12), there is any need at all for a supply flow.

  • Patent number: 8424554
    Abstract: An improved control valve for a reverse osmosis (RO) water purification system for supplying relatively pure water for on-demand dispensing, wherein the improved control valve positively terminates pure water production and brine outflow to a waste or drain when a pure water reservoir reaches a substantially filled condition. The control valve responds to a predetermined pressure differential between a tap or feed water inflow and produced pure water to close a pure water outflow line when the pure water reservoir reaches a substantially filled condition, thereby positively preventing further production of pure water. Shortly thereafter, the control valve closes a brine outflow line thereby positively preventing further water flow through the system until at least a predetermined volume of the reservoir-stored pure water is dispensed. When this occurs, the control valve re-opens in sequence the brine outflow and the pure water outflow lines.

  • Publication number: 20120291627
    Abstract: A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel. Presence of fluid or change in phase of flowing fluid within a fluid circuit may be sensed by comparing outputs of first and second temperature sensing elements, with one sensing element including a heater to increase temperature of the sensing element in exposure to gas but not in exposure to liquid.

  • Publication number: 20100212752
    Abstract: A system that shuts down water flow to a water heater of a residence or commercial building upon detecting a leak that includes first and second valves, and first and second valve actuators that operate to control the first and second valves, respectively. Preferred systems also include first and second sensors that measure the flow of water into and out from water heaters, respectively. Preferred systems further include controllers that receive signals from each of the first and second sensors. Such controllers controllably communicate with each of the first and second valve actuators to close the first and second valves, respectively, when a flow difference is detected that is greater than a predetermined threshold.

  • Publication number: 20080229845
    Abstract: A beverage dispenser provides numerous inventive features in its refrigeration system, diluent delivery system, concentrate delivery system, mixing and dispensing system, and control system. The refrigeration system employs a plate heat exchanger to provide on demand refrigeration of an intermittent water flow. The diluent delivery system includes a flowmeter/solenoid/check-valve assembly. The concentrate delivery system employs a positive displacement pump. The mixing and dispensing system includes a mixing nozzle that has a locking feature such that an elevated blocking surface directly faces the inlet of pressurized diluent to create turbulence. The control system receives package-specific information from a scanner and diluent flow rate information from the flowmeter, and then determines the pump speed in order to set a desired mix ratio.

    Abstract: A drained water recovery system of a process device and recovering method thereof is provided. The recovering method includes using a conductivity meter to measure the conductivity of the drained water so that the drained water with different degrees of conductivity are channeled to different pipelines. Furthermore, another conductivity meter and a total organic carbon analyzer together with an interim tank liquid level controller sorts out the recovered water. Thereafter, according to the properties of the recovered water, the drained water is re-used to improve recycling efficiency.

  • Patent number: 6932102
    Abstract: The present invention relates to a device for regulating the flow rate and/or the pressure of a fluid transferred from a high-pressure reservoir (H) to a reservoir (S). A first valve (1) provided with a control (2) is mounted in a pipe (10, 11, 12) connecting the two reservoirs (H, S). A Laval nozzle (3) located downstream of the first valve (1) is provided with an electrical pressure-drop sensor (4). A second valve (5) provided with a control (6) is connected between the downstream part of the Laval nozzle and an exhaust orifice (R). A micro-programmed system (7), designed to receive the values read by the pressure-drop sensor (4) and to drive the two controls (2, 6) of the two valves (1, 5) makes it possible to regulate the flow rate and/or the pressure of the fluid transferred from the first reservoir (H) to the second reservoir (S).
