Inventor: TANNER SCOTT D
IPC: H01J49/10
Filed: 2000-11-24
Abstract: A spectrometer apparatus and method provides a modulated stream of ions whic h can be from the source that is inherently modulated, or a continuous source that is subject to some modulation or gating technique. The ions are then delivered as a pulse or a series of pulses of ions into a pressurized reacti on cell, in which reaction and/or collision with gas in the cell occurs. The io ns are then passed from the pressurized cell into a mass analyzer for detection . The mass analyzer, ion detector or ion induced signal processing system are operated in such a manner that only ions that arrive at the detector in a period of time set relatively to the time of release of pulses of ions are used for analysis. It has been found that by careful selection of this perio d, enhanced specificity can be achieved and the effect of interference ions can  be reduced.

Title: Extended life traveling grate side plate
Inventor: FORESMAN JAMES D
IPC: F23H11/18
Filed: 2001-03-12
Abstract: An extended life traveling grate side plate having a heat transfer opening formed in a front portion of the side plate. The side plates are attached to the lateral side surfaces of each chain in a traveling grate conveyor. The front portion of each side plate overlaps the back portion of the preceding side plate such that the back portion of each side plate is covered and prevented from radiating heat away from the side plate. The heat transfer opening formed in the front portion of each side plate facilitates greater heat transfer from the overlapped area of the side plate. The front portion of the side plate is generally planar and does not include any gussets, thereby eliminating the heat transfer properties of the gussets and creating a more uniform thermal expansion of the side plate (147).

Abstract: A method of polishing and cleaning a glass surface with a single abrasive article (13, 13'). The abrasive article (13, 13') includes ceria abrasive particles dispersed in binder, the abrasive article having a textured, three - dimensional abrasive coating. The method includes contacting the glass surfa ce with the abrasive article (13, 13') at a desired pressure and in the presenc e of water, and moving the abrasive article (13, 13') and glass in relation to  each other under pressure. The water is believed to mediate a chemical reaction involving the ceria and the glass, thereby leaving a haze on the glass surface. With continued motion of the abrasive article (13, 13') in relation to the glass workpiece, without the addition of additional water, t he haze is removed.
