    Abstract: The present invention relates to a device for liquid degassing by means of swirling or centrifugal force coupled with a pressure gradient. This device comprises a cavity. The cavity is furnished with an inlet for liquid-gas mixture, a gas outlet and a liquid outlet. The gas outlet is inserted into the cavity through the top end of the cavity and positioned around 0.1-3 times the maximum diameter of the cavity from the top of the cavity.

  • Patent number: 9764968
    Abstract: A method and system of providing ultrapure water for semiconductor fabrication operations is provided. The water is treated by utilizing a free radical scavenging system and a free radical removal system. The free radical scavenging system can utilize actinic radiation with a free radical precursor compound, such as ammonium persulfate. The free radical removal system can comprise use of a reducing agent. The ultrapure water may be further treated by utilizing ion exchange media and degasification apparatus. A control system can be utilized to regulate addition of the precursor compound, the intensity of the actinic radiation, and addition of the reducing agent to the water.

  • Patent number: 9597422
    Abstract: An apparatus for generating ozone inside packaged articles comprises an electrode assembly in which coplanar electrodes are supported along a contact surface. The electrodes are solid state conductive electrodes. These electrodes may be interdigitated and/or arranged with uniform spacing therebetween along a portion of their length. Where the electrodes are straight they may be parallel, but other shapes can also be evenly spaced. In some examples the electrodes are partially insulated and partially exposed. In some examples the electrodes are embedded/potted in an insulator to exclude air spaces from around the electrodes.

  • Patent number: 9474817
    Abstract: Systems and methods for monitoring and compensating for bleach concentration changes within a disinfection system may be provided. A bleach concentration monitor may be introduced into a disinfection system to measure the percentage concentration of a bleach precursor that may be introduced into a mixer and then report the measurements to pump controls within the disinfection system. Data relating measurements of the concentration of the bleach precursor may be transmitted to pump controls within the disinfection system so that adjustments may be made to a control algorithm within the pump controls to compensate for any changes that may be observed related to bleach concentration in the system.

  • Patent number: RE47244
    Abstract: An alarm suspend system utilizes an alarm trigger responsive to physiological parameters and corresponding limits on those parameters. The parameters are associated with both fast and slow treatment times corresponding to length of time it takes for a person to respond to medical treatment for out-of-limit parameter measurements. Audible and visual alarms respond to the alarm trigger. An alarm silence button is pressed to silence the audible alarm for a predetermined suspend time. The audible alarm is activated after the suspend time has lapsed. Longer suspend times are associated with slow treatment parameters and shorter suspend times are associated with fast treatment parameters.
