摘要： A tool insert comprising a composite diamond abrasive compact and a method of its production are provided. The composite abrasive compact is characterized by an intermediate layer between the diamond compact and the cemented carbide support. The intermediate layer consists essentially of discrete cubic boron nitride particles constituting 60 to 40 percent by volume of the intermediate layer, carbide particles, preferably tungsten carbide particles and diamond solvent, preferably cobalt. The carbide particles and diamond solvent together constitute 40 to 60 percent by volume of the intermediate layer and the diamond solvent constitutes 15 to 25 percent by volume of the carbide/solvent combination.

摘要： A refractory roll cover is described that reduces the amount of noxious dust during the production of glass sheet. The roll cover comprises a plurality of segments, including low dusting millboard segments mechanically supported by highly rigidized compressed fiber segments. The millboard segments are adapted to contact the glass sheet. The millboard is chosen so that any dust produced has little affinity for the glass sheet or is not easily fluidized by convective currents. The highly rigidized compressed fiber has a fused surface that releases little dust. The resultant roll cover substantially eliminates dusting while providing a mechanically superior roll cover.
摘要翻译：描述了一种在玻璃板生产期间减少有害灰尘的量的耐火辊盖。辊盖包括多个段，包括由高度刚性化的压缩纤维段机械地支撑的低灰尘刨花板段。铣板段适于接触玻璃板。选择该刨花板使得产生的任何粉尘对玻璃板具有很小的亲和力，或者不容易被对流电流流化。高度刚性化的压缩纤维具有很少的灰尘的融合表面。所得的辊盖基本上消除了粉尘，同时提供了机械上优越的辊盖。

摘要： The invention includes an end cap that can be securely mounted to the end of a ceramic spool. The end cap comprises a locking plate adapted to fit into a groove in the ceramic spool. A plurality of angularly offset holes in the locking plate align with similar holes in the end cap. Screws or pins are placed in the holes and welded in place to prevent backing out or loosening. In use, the locking plate is secured by the pins, the groove and the inside surface of the end cap, the combination of which inhibits misalignment. Thermal cycling does not loosen the end cap, cause eccentric rotation or crack the ceramic spool.
摘要翻译：本发明包括可以牢固地安装到陶瓷阀芯端部的端盖。端盖包括适于装配到陶瓷卷轴中的凹槽中的锁定板。锁定板中的多个角度偏移的孔与端盖中的类似的孔对准。螺钉或销钉放置在孔中并焊接到位，以防止退出或松动。在使用中，锁定板通过销，槽和端盖的内表面固定，其组合阻止了未对准。热循环不会松动端盖，导致偏心旋转或破裂陶瓷阀芯。

摘要： A composite abrasive compact is produced by placing strips of suitable abrasive material on a cemented carbide substrate. The strips each comprise abrasive particles, optionally with a particulate second phase, in an organic binder. The organic binder is first removed by volatilization. Then, the cemented carbide substrate with the strips thereon is subjected to compact-producing conditions of elevated temperature and pressure.
