摘要： A dry pressing and slip casting process is provided for the manufacture of glass-ceramic components of the type used in sensors. Both process on starts with a powder composition of SiO2 (42-59 wt. %), Al2O3 (17-35 wt. %), MgO (2-25 wt. %) and also BaO (0-20 wt. %), TiO2 (0-12 wt. %), ZnO (0-10 wt. %), CaO (0-10 wt. %), B2O3 (0-5 wt %), P2O5 (0-5 wt. %), ZrO2 (0-5 wt. %), alkali oxides such as K2O, Na2O (0-3 wt. %) and other small amounts (0-1 wt. %) of additives such as Fe2O3, As2O3. Fe2O3, V2O5, As2O3. Some of the ingredients (e.g. Mg, Ba, Ca) can also be present in the form of fluoride, e.g., MgF2, BaF2, CaF2, to up to 10 wt. %. Additional ceramic additives up to 30 wt. %, which are as second phase (e.g., Al2O3, Y2O3 doped ZrO2, SiO2, mullite, zircon, carbides, nitrides, and a combination of the above), are not part of the glass composition, but are introduced to enhance both the mechanical strength and toughness and to further modify the coefficient of thermal expansion. In the dry pressing process the powder is milled, blended with a binder and then subjected to a drying/granulation process. A die cavity of a desired shape is then filled with the powder. Pressure is then applied to die for a period of time. After the pressure is removed, the green ceramic part is ejected and then sintered to become a finished ceramic cover or header. In the slip casting process, the powder is milled and dispersed in a water. The slip is then poured or pumped into a permeable casting mold of a desired shape made of Gypsum. When either the liquid has been completely sucked away by the mold or the desired depositing thickness has been reached, the cast green ceramic part is removed from the mold, dried and then sintered into a finished ceramic cover or header.

摘要： An improved circular saw blade designed for cutting fiber cement workpieces, which are becoming more and more prevalent on the construction site, includes a PCD/carbide tip mounted in the rim of a saw blade at six, rather than the usual four locations, equally spaced around the blade. The tips are mounted adjacent a relatively large-diameter, semi-circular gullet, which itself is preceded by a chip and dust minimizer. The minimizer includes several alternating hills and valleys formed in the rim of the saw blade, each hill and valley having the same radius, producing a sinuous array essentially centered on the rim of the blade. It has been discovered that such a dust and chip minimizer reduces the level of dust and chips produced by the blade and clears the same from the kerf generated in the blade-workpiece interface. Ideally, all of the parameters and relief angles for the surfaces on the saw blade tip can be generated by cutting an array of such tips from a large-diameter blank of PCD fused to a layer of tungsten carbide, and by mounting the tips onto the blade in such an orientation as to present, preferably, a negative hook or rake angle to the workpiece.

摘要： An improved circular saw blade designed for cutting fiber cement workpieces, which are becoming more and more prevalent on the construction site, includes a PCD/carbide tip (16) mounted in the rim (31) of the saw blade (10) at six, rather than the usual for locations, equally spaced around the blade. The tips are mounted adjacent a relatively large-diameter, semi-circular gullet (20), which itself is preceded by a chip and dust minimizer (18). The minimizer includes several alternating hills (52) and valleys (54) formed in the rim of the saw blade, each hill and valley having the same radius, producing a sinuous array essentially centered on the rim of the blade. It has been discovered that such a dust and chip minimizer reduces the level of dust and chips produced by the blade and clears the same from the kerf generated in the blade-workpiece interface. Ideally, all of the parameters and relief angles for the surfaces on the saw blade tip can be generated by cutting an array of such tips from a large-diameter blank (110) of PCD fused to a layer of tungsten carbide (72), and by mounting the tips onto the blade in such an orientation as to present, preferably, a negative hook or rake angle (74) to the workpiece.
