Abstract: A device and method are disclosed. The device may be mountable in a band saw table with a miter slot parallel to the cutting plane. An anchor bar may be mountable in the miter slot. A first and second guide bar may be perpendicularly connected to the anchor bar extending away from the cutting plane. A base may be slideably engaged to the first and second guide bar to allow the base to have transverse movement relative to the cutting plane. A guide rail may be connected to the base, wherein the guide rail may be perpendicular to the first and second guide bar, and may be positioned parallel to the anchor bar. A carriage may be slideably engaged to the guide rail for movement along the guide rail in a direction parallel to the cutting plane, the carriage may have a mounting surface for mounting a workpiece.

Abstract: A new Rhenium alloy usable for improving the performance of emission filaments used in mass spectrometers or other similar scientific instruments, which is made by adding low level concentrations of Yttrium Oxide to Rhenium of less than 10%. This new alloy has demonstrated superior performance characteristics compared to pure Rhenium for this purpose. Filaments made from the Yttria/Rhenium alloy exhibit the same voltage, current and emission properties as Rhenium but have the added advantage of greatly decreasing warping during use. The Rhenium alloy filaments are usable with various shapes and configurations including straight filaments, multiple coiled filaments and pin shaped filaments. Electron microscopy and microscopy studies verify that the Yttria/Rhenium material of the new alloy has a smaller grain size and increased strength when compared to pure Rhenium, which accounts for the enhanced structural strength.

Abstract: A cryogenic trap apparatus for cooling is disclosed as well as heating of a capillary column in order to analyze the volatile components of any volatile or semi-volatile compound passing through the capillary column. The cryogenic trap is restricted to treatment of one inch or less in length of the capillary column in order to achieve miniaturization of the design. A cylindrically shaped main cryogenic chamber with a volume of less than 0.5 cubic inches is adapted to receive the capillary column extending axially therethrough and includes a cooling fluid inlet and a cooling fluid outlet as well as a heating apparatus for achieving rapid cooling and thereafter rapid heating of the components in the capillary column for trapping and segregating individual components thereof for chromatographic analysis.
