  • Patent number: 11905172
    Abstract: A novel concept for a high energy and material efficient nitric acid production process and system is provided, wherein the nitric acid production process and system, particularly integrated with an ammonia production process and system, is configured to recover a high amount of energy out of the ammonia that it is consuming, particularly in the form of electricity, while maintaining a high nitric acid recovery in the conversion of ammonia to nitric acid. The energy recovery and electricity generation process comprises pressurizing a liquid gas, such as air, oxygen and/or N2, subsequently evaporating and heating the pressurized liquid gas, particularly using low grade waste heat generated in the production of nitric acid and/or ammonia, and subsequently expanding the evaporated pressurized liquid gas over a turbine. In particular, the generated electricity is at least partially used to power an electrolyzer to generate the hydrogen needed for the production of ammonia.

  • Patent number: 11806742
    Abstract: Various embodiments concern a sprayer having a blower that outputs a HVLP flow of air into a hose, the hose connecting with a spray gun. A pressure sensor measures pressure of the HVLP air within the hose via a tube that branches from a fitting to which the hose connects. If the sensor indicates that the pressure level has increased above a threshold amount, indicating that the trigger of the spray gun is not being actuated, then power output to the blower is reduced (e.g., stopped). HVLP air is trapped within the hose by two valves when the trigger is not actuated. When the sensor indicates that the pressure level has decreased, corresponding to release of the trapped HVLP air into the gun for spraying by actuation of the trigger, power to the blower is increased (e.g., resumed).

  • Patent number: 10030315
    Abstract: A non alpha controlled Tin including Tin and a trace amount of Polonium is utilized as a plating anode to selectively plate Tin upon a plating cathode. Tin may be selectively plated by pulse plating the non alpha controlled Tin with current control to suppress plating of Polonium upon the plating cathode. Tin may also be selectively plated by pulse plating the non alpha controlled Tin with potential control to suppress plating of Polonium upon the plating cathode. Tin may also be selectively plated by pulse and reverse plating to plate out Polonium upon a filtering cathode. Tin may also be selectively plated by plating out Polonium upon a filtering cathode within a concentrate. Tin may also be selectively plated by plating out purified Tin upon a filtering cathode, separating the purified Tin from the filtering cathode, and utilizing the purified Tin to plate Tin upon the plating cathode.

  • Patent number: 9925323
    Abstract: Systems and methods for monitoring the presence of blood in an extracorporeal blood circuit are disclosed. A control unit, which is connected to a blood detector and to one or several pressure sensors, determines whether blood is present in the membrane device based on the differential pressure there over and generates a signal if the presence of blood as detected by the blood detector and the presence of blood as determined based on the differential pressure value do not coincide with each other.

  • Patent number: 9650936
    Abstract: An object of the present invention is to detect an abnormality in an exhaust gas purification apparatus having an NSR catalyst and an SCR catalyst disposed on a downstream side of the NSR catalyst more favorably. Air-fuel ratio reduction control is executed to reduce NOx occluded to the NSR catalyst when an integrated value of an amount of NOx flowing into the NSR catalyst reaches an upper limit value of an amount of NOx that can be occluded to the NSR catalyst in a normal condition. It is determined whether or not the exhaust gas purification apparatus is in an abnormal state on the basis of a NOx purification ratio of the exhaust gas purification apparatus calculated at this time.

  • Patent number: 9540237
    Abstract: Disclosed herein is a gas generator that contains a liquid reactant that reacts to produce a gas in the presence of a catalyst. The catalyst is contained in a carrier that is buoyant in the liquid reactant. The gas generator also has at least one carrier movement restraining member adapted to selectively control the location of the carrier, and at least one compressible body containing a volume of gas. In a first configuration, when an internal pressure of the gas generator is lower than an internal pressure of the compressible body, the compressible body increases in volume, and in a second configuration when the internal pressure of the gas generator is higher than the internal pressure of the compressible body, the compressible body decreases in volume. The carrier movement restraining member restricts the carrier's movement in the first configuration.
