Patent number: 7319222Abstract: A linear trap which allows for charge separation and ion mobility separation in a speedy manner, and enables measurement with high duty cycle. A mass spectrometer comprises an ion source, an ion trap for trapping ions ionized by the ion source, an ion trap controller for controlling a voltage on an electrode included in the ion trap, and a detector for detecting the ions ejected from the ion trap. The ion trap controller includes a table for each mass-to-charge ratio, the table containing a frequency of the voltage used for charge separation, and a gain of the voltage for ejecting a first ion with a first charge outside the ion trap, and retaining in the ion trap a second group of ions with a second charge that is lower than that of the first charge. The ion trap controller controls the voltage based on the mass-to-charge ratio set. The mass spectrometer has significantly improved sensitivity, as compared to the prior art.Type: GrantFiled: January 5, 2006Date of Patent: January 15, 2008Assignee: Hitachi High-Technologies CorporationInventors: Yuichiro Hashimoto, Hideki Hasegawa, Izumi Waki

Patent number: 7288139Abstract: An apparatus separates liquid, gas and solid components of a mixture in a fluid system. An inlet for receiving the mixture opens into a separation chamber tangentially with a cylindrical side wall and a gas outlet has an opening in a first end wall adjacent the inlet to allow gas to exit the separator. A fluid outlet is located in an opposing second end wall. A debris passage extends through the cylindrical side wall and oriented so that the radial velocity of the particles within the separation chamber directs the particles through the debris passage. The debris passage leads to a particle collection chamber in which the particles accumulate. Unlike prior separators that relied on the tangential velocity of the particles, the present apparatus utilizes the greater radial velocity to drive the particles from the separation chamber into the particle collection chamber.Type: GrantFiled: September 6, 2006Date of Patent: October 30, 2007Assignee: Eaton CorporationInventor: Stephen Showalter

Patent number: 7288138Abstract: An apparatus separates liquid, gas and solid components of a mixture in an engine lubricating system. An inlet for receiving the mixture opens tangentially into a separation chamber and a gas outlet has an opening in a first end wall adjacent the inlet to allow gas to exit the separator. A fluid outlet is in an opposing second end wall and opens into a lubricant reservoir of the engine lubricating system. Both liquid and gas flow through the fluid outlet between the separator and the reservoir. A particle collector is provided adjacent the second end wall to receive solids that become separated from the mixture. A baffle may be provided to direct the separated liquid from the separator into the reservoir while allowing gas in the reservoir to flow into the separator.Type: GrantFiled: November 22, 2004Date of Patent: October 30, 2007Assignee: Eaton CorporationInventors: Stephen Showalter, Edward G.

Patent number: 7223335Abstract: A device for separating ions from a fluid stream is disclosed. The device includes multiple chambers in fluid communication with one another. A first chamber has an inlet, and a last chamber has an outlet. The inlets and outlets of intermediate chambers are connected to one another so that fluid flows in a circular pattern through each chamber. A magnetic field extends through the chambers perpendicular to the flow. The magnetic field induces a force on the ions, moving ions of one polarity to ward the center of the chambers and ions of the opposite polarity toward the periphery of the chambers. Each chamber has an outlet for drawing fluid from the chamber center. The circulation direction reverses in each chamber allowing both positive and negative ions to exit via the outlets. Fluid of reduced ion concentration exits the outlet channel.Type: GrantFiled: August 15, 2006Date of Patent: May 29, 2007Inventor: Henry R. Dunlap

Patent number: 6939469Abstract: A band gap mass filter for separating particles of mass (M1) from particles of mass (M2) in a multi-species plasma includes a chamber defining an axis. Coils around the chamber generate an axially aligned magnetic field defined (B=B0+B1 sin ?t), with an antenna generating the sinusoidal component (B1 sin ?t) to induce an azimuthal electric field (E?) in the chamber. The resultant crossed electric and magnetic fields place particles M2 on unconfined orbits for collection inside the chamber, and pass the particles M1 through said chamber for separation from the particles M2. Unconfined orbits for particles M2 are determined according to an ?-? plot ( ? = ? 0 2 + ? 1 2 / 2 4 ? ? 2 , and ? ? ? ? = ? 0 ? ? 1 8 ? ? 2 ) , where ?0 is the cyclotron frequency for particles with mass/charge ratio M, and wherein ?0=B0/M and ?1=B1/M.Type: GrantFiled: December 16, 2002Date of Patent: September 6, 2005Assignee: Archimedes Operating, LLCInventors: Tihiro Ohkawa, Robert L.
