Abstract: A valve with a smart handle including a memory module to log relevant data. A sensor on the handle determines when the valve is open, and this triggers the start of timers and recording of the “open” event in a log in the memory module. When the valve is closed, the sensor triggers stopping of the timers and recording of the “closed” event in the log. The timer information is used to calculate the duration of the time “open” event, and this, together with the actual date and time of the opening and closing of the valve are recorded in the log. Other relevant information, such as cylinder fill date, cylinder I.D. number, batch number, and patient name or account number may also be logged in the memory module. The log of the events and the corresponding dates and times may be used to prepare invoices for billing gas treatments, for inventory control, and for other record-keeping and control functions.

Abstract: A method is provided for fabricating a constriction region in a channel of a microfluidic device. The method includes the steps of introducing a pre-polymer mixture including a monomer, cross-linking agent and photoinitiator into the channel. The pre-polymer mixture is polymerized at a localized area of the channel so as to shrink and solidify the liquid mixture. The solidified and shrunken liquid mixture provides the constriction region in the channel.

Abstract: A diluent passage 12 to introduce special liquid and a rinse liquid supply passage 13 which is separate from the diluent passage 12 are formed in the main body 10, and a plurality of jets are disposed at a cylindrical dial 18. A water convey passage is formed to connect two positions at the rinse liquid supply passage 13 where pressure difference occurs therebetween to the other jets 19b, 19c except the jet 19a through which the special liquid is introduced. When water flows in the rinse liquid supply passage 13, the water is introduced to the water convey passage due to the pressure difference of the rinse liquid supply passage 13. The water rinses the other jets 19b, 19c except for the jet 19a through which the special liquid is introduced. Therefore, adjusting changes or choking of the jets 19b, 19c which have not been used for a considerable time can be prevented.

Abstract: A hydraulic pressure compensation system for valve actuator assemblies is described having particular application for subsea wellhead installations. The compensation system includes at least one valve actuator assembly having a housing that retains a reciprocable piston therewithin. The piston is spring biased into its fail safe configuration. The valve actuator assembly is hydraulically associated with an accumulator reservoir that defines a closed fluid reservoir and an open fluid reservoir that is exposed to ambient pressures. The two chambers are separated by a membrane. The valve actuator assembly is also operationally associated with a fluid pressure intensifier that boosts the ambient pressure of the accumulator so that an increased fluid pressure may be transmitted to the actuator assembly to bias the actuated valve toward its fail safe configuration. In a described embodiment, the fluid pressure intensifier comprises a housing that defines a chamber having a fluid inlet and fluid outlet.

Abstract: A fluidic pulse generator system includes two fluidic diverter valves that are both controlled by a single fluidic pilot valve. The fluidic pilot valve and the two fluidic diverter valves are each adapted to receive a flow of pressurized fluid. The flow of pressurized fluid through the fluidic pilot valve is controlled in response to pressurized fluid flow through a control valve. In turn, the flow of pressurized fluid through the two fluidic diverters valves is simultaneously controlled in response to the flow of pressurized fluid through the fluidic pilot valve.

Abstract: A valve security device for releasably securing a fluid flow valve in an inoperable position including an inner body adapted to be disposed about the valve actuator such that rotation of the inner body effects corresponding rotation of the actuator to open and close the valve and an outer body rotatably mounted about the inner body. A valve cap defining a secondary actuator is mounted on the outer body. An operating pin assembly is carried by the outer body which, in an extended position, operatively couples the outer body to the inner body such that the valve can be controlled by the secondary actuator. In a retracted position, the pin assembly uncouples the outer and inner bodies such that the outer body is freely rotatable on the inner body. A lock secures the operating pin assembly in the retracted position thereby releasably securing the valve in an inoperable position.

Abstract: The present recreational vehicle water warming and circulating system uses the heated water in the water heater to heat the on-board water supply when the outside air temperature drops below the freezing point of water. The system includes a holding tank for containing a majority of the on-board water supply, and heated and cold loops that supply heated and cold water to various fixtures in the recreational vehicle. When temperature sensors sense a potentially freezing condition, a control circuit opens one or more solenoid valves to open the one or both loops to return undispensed heated or cold water to the holding tank. The control circuit closes the solenoid valves when the potentially freezing condition is no longer detected by the temperature sensors.

Abstract: A freezeless wall hydrant for delivery of hot or cold water from a single discharge conduit has first and second fluid inlet pipes in parallel spaced relation. The pipes have forward and rearward ends and are connected respectively to sources of hot and cold pressurized water. A laterally extending fluid conduit member connects the forward ends of the first and second fluid inlet pipes and is in communication therewith. A fluid closure valve is located in the rearward ends of each of the first and second fluid pipes. A check valve is in each of the pipes forwardly of the fluid closure valves and is capable of permitting fluid flow in the pipes in a direction from the closure valve, but prevents fluid flow towards the closure valves. A valve rod having forward and rearward ends rotatably extends through the laterally extending fluid conduit and through the forward ends of the first and second inlet pipes and has one end operatively connected to the check valves in the rearward ends of the fluid inlet pipes.
