Harold P Bovenkerk, Paul D Gigl: Temperature resistant abrasive compact and method for making same. General Electric Company, Morgan Finnegan Pine Foley & Lee, September 23, 1980: US04224380 (365 worldwide citation)

In one embodiment, a compact for tools, such as cutting, drilling and shaping tools, consists essentially of self-bonded abrasive particles. The bonded particles define a substantially continuous interconnected network of pores, dispersed throughout the compact. The method for making such a compact ...

Paul D Gigl, Hyun S Cho: Sweep through process for making polycrystalline compacts. General Electric Company, Robert R Schroeder, May 21, 1985: US04518659 (50 worldwide citation)

The high pressure/high temperature catalyst sweep through process for making diamond and cubic boron nitride compacts has been improved by adding an intermediate metal or metal alloy. The added metal (whether alone or contained in an alloy) has a melting point below that of the catalyst (e.g. cobalt ...
