Title: Method for sulfuration of tin refining sulfur slag
Inventor: YANG BIN
IPC: C22B25/06
Filed: 2018-01-29
Abstract: A method for sulfuration of a tin refining sulfur slag, comprising: uniformly mixing the sulfur slag and a sulfurizing agent, then placing the mixture into a sealed container, and performing a sulfuration reaction under the oxygen-free conditions and whilst stirring so as to change a non-sulfided metal element which is easy to be sulfuretted in the sulfur slag into a sulfided state, thus increasing the volatility of the metal. The sulfuration rate of the metal in the sulfur slag is 99.5% or higher, and the product after sulfuration can be further separated by means of vacuum distillation.

Title: Suspension apparatus intended for electrical cables
Inventor: DOBIDA REINHARD
IPC: H02G1/02

Title: Randomly-oriented polycrystalline silicon carbide coatings for abrasive grains
Inventor: HAYDEN STEPHEN CHARLES
IPC: C08J5/14
Filed: 1982-02-05
Abstract: Disclosed is a composite abrasive particle comprising a core abrasive crystal and a silicon carbide coating adherently bonded to substantially all of the exterior surfaces of said core crystal, said silicon carbide coating characterized by silicon carbide crystals having a random orientation substantially independent of the structure of the core crystal, the outer surface of the coating being conformationally irregular. Aggregates of the composite abrasive particles are interconnected by a matrix of silicon carbide which has an open structure. Preferred core abrasive crystals are diamond or cubic boron nitride. The composite abrasive particles preferably are male by infiltrating core crystals coated with non-diamond carbonaceous material with fluid silicon to produce a mass of core crystals bonded together by silicon carbide and elemental silicon, leaching substantially all of the silicon from the bonded mass with a silicon leaching agent, sub-dividing the resulting leached mass, and recovering the composite abrasive particles.
