Patent number: 7405398Abstract: A mass spectrometer interface, having improved sensitivity and reduced chemical background, is disclosed. The mass spectrometer interface provides improved desolvation, chemical selectivity and ion transport. A flow of partially solvated ions is transported along a tortuous path into a region of disturbance of flow, where ions and neutral molecules collide and mix. Thermal energy is applied to the region of disturbance to promote liberation of at least some of the ionized particles from any attached impurities, thereby increasing the concentration of the ionized particles having the characteristic m/z ratios in the flow. Molecular reactions and low pressure ionization methods can also be performed for selective removal or enhancement of particular ions.Type: GrantFiled: April 18, 2006Date of Patent: July 29, 2008Assignee: IONICS Mass Spectrometry Group, Inc.Inventors: Charles Jolliffe, Gholamreza Javahery, Lisa Cousins

Patent number: 6493244Abstract: A massive choke coil [e.g. exceeding about three henries, with at least a thousand turns and a relatively low internal resistance of about eleven ohms] placed in parallel with the A/C line, that is, preferably across the A/C line's “hot” and “common” lines, quenching the reflected signal (or back emf) that is developed when any power amplifier or other load places its demands upon the incoming A/C power line. Due to its electromagnetic characteristics, the choke tends to provide a momentary high current source of energy when needed by, e.g., a power amplifier (or other appropriate load) when transient demand is called for. The parallel choke approach tends to have a reversing effect on this signal, at least substantially reducing its presence on the A/C line, providing a greatly enhanced A/C power line signal quality, without which the otherwise untreated signals are able to modulate the A/C line.Type: GrantFiled: May 18, 2001Date of Patent: December 10, 2002Assignee: Richard Gray's Power Co. (A La. Limited Liability Co.)Inventor: Richard Gray

Patent number: 6365235Abstract: A surface treatment method wherein one or more active particle streams are generated and aimed at a surface to be treated so that the particle stream interacts therewith. The active particle stream consists of activated particles forming chemically active sites on the surface, and modifying particles occupying said sites. The energy of the activated particles is greater than the energy at break of the inhibited surface bonds of the surface, and lower than the radiative flaw formation energy on the surface. The strength of the particle stream at the treated surface is greater than a quantity N/t where N is the surface density of the inhibited bonds to be broken and t is the duration of exposure of any point on the treated surface to the stream. A device for carrying out the method is also provided.Type: GrantFiled: May 13, 1998Date of Patent: April 2, 2002Assignee: TePla AGInventors: Pavel Koulik, Evgenia Zorina
