  • Patent number: 9645585
    Abstract: A variable flow rate gas control valve for use in consumer and commercial appliances is presented. The valve utilizes two or more solenoids to control the operating position of two different valve members whose orifices are sized in an exponential relationship with one another. By opening one or more of the valving members in various combinations, a variable flow rate of gaseous fuel may be controlled in integer multiple steps from full off to full on. The solenoid configurations may be in line, opposing, or symmetrical about an axis of the valve. The number of unique flow rates (F) is related to the number of solenoids (N) as F=2N. The relationship between the size (S) of the individual gas control orifices for each of the solenoids is related to N by the relationship S=2n?1 for each individual gas control orifice (n) numbered 1 to N.

  • Patent number: 8973606
    Abstract: The present invention is one that prevents standard gas from remaining in a standard gas line to prevent a concentration of standard gas from being reduced due to adsorption, modification, or the like, and has: a diluent gas line provided with a diluent gas flow rate controlling mechanism; a standard gas line provided with a standard gas flow rate controlling mechanism; an output gas line joined by the diluent gas line and standard gas line and outputs the standard gas having a predetermined concentration; an exhaust gas line connected to an upstream side of the standard gas flow rate controlling mechanism in the standard gas line and provided with an on/off valve and a flow rate control part; and a control part that, depending on a flow rate of the standard gas flowing through the standard gas line or the type of the standard gas, switches on/off the on/off valve.

    Abstract: An apparatus for mixing a first liquid with at least a second liquid includes a tank having a mixing chamber to which is connected a first and a second supply line from each of a first and a second source of liquid. A gross control valve disposed in each of the first supply lines and a fine control valve disposed in each of the second supply lines. A noncontacting detector measures the total volume of liquid present in the mixing chamber. A controller, operable in response to signals output from the detector representative of the total volume within the mixing chamber as continuously measured by the detector, actuates in accordance with a predetermined sequence the gross and the fine control valves in the respective first and second supply lines from the first source and from the second source in accordance with a predetermined sequence.
