Abstract: Dense silicon carbide abrasive grain is produced by forming grains of the desired size and shape from a formable mix comprising finely divided silicon carbide, carbon and a temporary binder, feeding these grains and silicon at a controlled rate into a reaction zone which has a non-oxidizing atmosphere at a temperature between 1800 C. and the decomposition temperature of silicon carbide, continuously moving the grains, in the presence of silicon, through the reaction zone and cooling and collecting the silicon carbide abrasive grains produced. The non-oxidizing gas may be argon. The source of silicon carbide is preferably finely divided silicon carbide formed by crushing silicon carbide ingots. Some of the carbon may be provided by the temporary binder which carbonizes on heating. Specified contents of the mix are 3-30% by dry weight of carbon and 67-94% by dry weight of silicon carbide. Specified temporary binders are starch and water-soluble methyl celluloses, which may be used with water, and synthetic resins which may be used with an organic solvent.

Title: Warping on section warping beams
IPC: D02J1/00
Filed: 1977-03-17
Abstract: In order to prevent loops and fluff from being pushed on during the processing of non-twisted or only slightly twisted threads, the individual filaments of a thread lying next to one another are swirled by means of compressed air and are thus interlaced at more or less large intervals. If this process is carried out simultaneously with the spinning or drawing process, only large interlacing intervals can be achieved because of the high thread speed. Here, the swirling is carried out simultaneously for all the threads, after the conclusion of the thread-producing process, in the course of the warping operation which takes place relatively slowly. The threads are thus drawn from a bobbin creel (15) via breaks, thread-guide members (16), an eyelet reed (17), a fluff monitor (20), an oiling device (21) and a thread store (22) and are wound onto part warp beams (24). The swirling device (18) is preferably installed between the eyelet reed and the fluff monitor. The swirl nozzles (9) are arranged close to one another in a common housing (1, 3) and are provided with a common air-supply system. The swirling process is controlled via a regulating valve and a three-way valve (4).

Filed: 1978-05-30
Abstract: A composition consisting of carbon powder, water and a dispersing agent. The particle size of the carbon powder is less than 100 mu m, preferably less than 40 mu m. The composition is obtained by preparing a mixture of about 1-20% by weight, preferably about 10% by weight, of carbonaceous powder, water and 0.02-4% by weight of dispersing agent.
