  • Patent number: 9586067
    Abstract: Systems and methods for mitigating the risk of and/or suppressing fires caused by lithium battery-powered personal computing devices used on the flight deck or in crew and passenger compartments onboard an aircraft. A fire detection and suppression pack is attached to a lithium-ion battery-powered portable personal computing device. The fire detection and suppression pack has a weight and volume consistent with and does not impair the use of the portable personal computing device. The fire detection and suppression pack is a full-time fire suppression system that is on hot standby at all times, independent of the computing device's power mode. The fire detection and suppression pack uses gases stored in canisters to provide cool-down, displacement suppressant to control and extinguish any fire source and associated burnable fuel required to sustain the fire event.

  • Patent number: 9528253
    Abstract: A controller assembly for an automatic flush valve provides economical approach to transforming a manual flush valve into an automatic flush valve. The controller assembly includes a base for holding a battery set and a sensor into a combination, and a cap covering the combination. A solenoid valve and a membrane below the combination are receiving in a socket of a foundation. A ring is rotatably mounted around a bottom of the foundation. A sleeve passing the cap is mounted around the foundation and stands on the ring. The ring allows the controller assembly to be easily assembled with a valve body of any type into an automatic flush valve or to be easily removed from the automatic flush valve and replaced by a manual controller assembly so as to form a manual flush valve. Thereby, the transformation can be economical accomplished without replacing the existing valve body.

During an on cycle when the on-off valve is open the wave generation component releases the process gas according to a time constant. A flow restrictor installed downstream in a throat of the on-off valve, outputs the rapid square waves to the conduit at a predefined magnitude. The flow restrictor is selected to have an impedance that is high enough to significantly raise the time constant during the on cycle such that pressure decay in each square wave pulse over the on cycle decreases to within a tolerance, wherein the time constant is at least in part a function of the flow restrictor impedance.

  • Patent number: 8615329
    Abstract: A control system is disclosed for regulating the flow of a liquid from a liquid provider through a liquid distribution system. The distribution system has a major liquid distribution channel connected to a plurality of minor liquid distribution channels providing the liquid to a multiplicity of users. A plurality of controllable user valves are interposed in the multiplicity of user channels. A liquid monitor senses a liquid flow characteristic within the liquid distribution channel. A user control changes selective controllable user valves for restoring a desired liquid flow characteristic within the liquid distribution channel.

  • Patent number: 8596299
    Abstract: An externally mounted mechanical device for mechanically closing a pressurized tank or cylinder valve, such as a grill tank, is provided. The device comprises a securing mechanism, a rotatable mechanism having a handle recess to receive a handle of pressurized tank or cylinder valve, and a torsional spring, wherein the torsional spring is configured to store potential torsional force and then release the torsional force by way of a timed release mechanism. The mechanical device comprises a securing device for securing the mechanical device to a tank or cylinder. Torsional force may be stored in torsional spring by way of a ratchet and pawl that also is configured to release the stored torsional force by way of a timed release.

  • Publication number: 20130276898
    Abstract: A method and a device for supply of a dialyser in a dialysis unit with dialysis fluid is disclosed. At least one dialysis fluid concentrate is mixed with water to produce the dialysis fluid. The dialysis fluid concentrate is prepared in a reservoir unit in a given amount. A control and arithmetic unit calculates the dialysis fluid rate (Qd) such that, after a given treatment time (TB) has passed, a given residual amount of dialysis fluid concentrate or no residual amount remains in the reservoir unit. It is preferable to empty the reservoir unit by the end of treatment.

  • Publication number: 20130247999
    Abstract: A system including a hydraulic accumulator, a pressure sensor, a fluid source and a data processor to detect a pre-charge pressure is provided. The hydraulic accumulator includes first and second fluid chambers and a separator therebetween. The hydraulic accumulator has an associated pre-charge pressure. The pressure sensor is connected to the first fluid chamber. The data processor is connected to the pressure sensor. The data processor is configured to determine a first and second rate of pressure changes, and a transition pressure between the first and second rates. The approximate pre-charge pressure is determined based on the transition pressure.

  • Patent number: 8511345
    Abstract: A method for controllably delivering hydrocarbon gas, comprises selectively opening and closing a valve to control the flow of hydrocarbon gas from a pressure vessel to a supply line for a hydrocarbon gas-fueled device, detecting any airborne hydrocarbon gas, attempting to move the valve from an open state to a closed state in response to detecting airborne hydrocarbon gas while the valve is in the open state, and releasing a liquid sealant to the supply line in response to detecting escaped gas after at least attempting to move the valve to the closed state.

  • Patent number: 8474788
    Abstract: The present invention provides a control device featuring a control module featuring one or more modules configured to provide a first control signal for controlling a first device in order to open or close a second device; and also configured to respond to a change in a parameter sensed in relation to controlling the first device, and to provide a second control signal for controlling the first device based at least partly on the change in the parameter in relation to time. The first device may be a motor; the second device is a valve; and the parameter may be current. In operation, the first control signal is for turning on the motor in order to open or close the valve, and the second control signal is for turning off the motor in order to open or close the valve.
