    Abstract: A system for the physical manipulation of free magnetic rotors in a circulatory system using a remotely placed magnetic field-generating stator is provided. In one embodiment, the invention relates to the control of magnetic particles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow. Examples of vascular occlusions targeted by the system include, but are not limited to, atherosclerotic plaques, including fibrous caps, fatty buildup, coronary occlusions, arterial stenosis, restenosis, vein thrombi, arterial thrombi, cerebral thrombi, embolisms, hemorrhages, other blood clots, and very small vessels.

    Abstract: A method and system for controlling a hydrocracker and fractionator reaction loop is disclosed. The method and system utilizes a sidedraw tray within the fractionator distillation zone upon which liquid is collected. This liquid is withdrawn as a sidedraw stream. The withdrawal of the liquid from the sidedraw tray is controlled based on the level of liquid on the sidedraw tray rather than at a set or determined flow rate. The sidedraw stream is separated into a first stream and a product stream. Unlike other processes where the flow rate of the product stream is set and the internal reflux flow rate varies, the method involves fixing the flow rate of the first stream that is returned to the distillation zone of the fractionators with the flow rate of the product stream being set so as to control the liquid level on the sidedraw tray.

  • Patent number: 8906326
    Abstract: A biochemical reaction cassette having a structure for uniformizing a liquid flow in a reaction chamber with a simple additional arrangement is provided. A fluid resistive section is arranged in a channel that is constructed to include an injection port, a reaction chamber, and a discharge port. The fluid resistive section decreases the cross-sectional area of the channel to decrease the fluid resistance at ends in the width direction of the fluid resistive section and at positions remote from the injection port and the discharge port, where the flow rate is decreased.

  • Publication number: 20140308186
    Abstract: Some industrial or fabrication processes generate effluent gas streams that require scrubbing. Scrubbing may include the use of one or more gases to abate the effluents for safer release into the environment. Systems and methods described herein provide a liquid-enclosed reaction chamber where an extended reaction zone or more than one reaction zone is formed. By having an extended reaction zone or more than one reaction zone, the effluent gas stream and the products of upstream reaction zones can be more completely abated. The reaction zones are formed by adding one or more gas ports into the reaction chamber downstream of a main burner nozzle.

    Abstract: An ammonia generating and delivery apparatus generating ammonia by heating a precursor material with a heating device controlled by a temperature pulse controller which receives commands from a pressure controller, and delivering ammonia with a flow rate controlled by a three-stage PWM controller. The temperature pulse controller is used in a first feedback loop to create a temperature pulse sequence at a surface of the heating device. A pressure controller in a second feedback loop provides duty-cycle commands to the temperature pulse controller, while in delivering ammonia, effects of pressure variation to delivery accuracy are compensated in the three-stage PWM controller, which includes a flow-rate feedback loop. The ammonia generating and delivery apparatus can also include two containers, in which the precursor material in one container is charged and discharged according to the capability of the other container in generating ammonia.

  • Patent number: 8808630
    Abstract: A method is disclosed for operating an exhaust gas catalytic converter designed to reduce nitrogen oxides in an exhaust gas flow using a solution that contains urea and that reacts to form at least ammonia in the exhaust gas flow. The method may include: introducing an amount of the solution containing urea upstream of the exhaust gas catalytic converter until an ammonia slip through the exhaust gas catalytic converter; determining a first actual value of the loading state of the catalytic converter with ammonia at the time of the slip; determining a first estimated value of the loading state at the time of the slip by means of a dynamic model for the loading; subsequently draining the ammonia from the catalytic converter; determining a second actual value of the loading state of the exhaust gas catalytic converter with the solution containing urea when the catalytic converter is drained as specified.
