Title: Production of refractories
Inventor: NISHIO HIDEAKI
IPC: C04B35/622
Filed: 1991-05-10
Abstract: PURPOSE:To decrease the molding pressure and shorten the molding times by curing a binder during molding so that baking after molding is not required. CONSTITUTION:A refractory source material containing aggregate and binder is mixed with a hardening agent such as polyamines, carbon dioxide, sodium silicate, p-toluenesulfonic acid, etc., coated with microcapsules which break under pressure during molding, and a binder such as phenol resin, furan resin and silica sol.

Filed: 1987-04-30
Abstract: PURPOSE:To prevent the dielectric breakdown of a cable corrosionproof layer and an insulating tube by connecting terminals in series on one side of a pair of corrosionproof layer layer protective devices (gapless arrester) and connecting terminals on the other side to flange sections of connecting pipes via conductive materials. CONSTITUTION:Screw-shaped tip sections 14' of terminals 14 on one side of gapless arresters 10 are connected in series via a copper plate 18A. Screw-shaped tip sections 16' of terminals 16 on the other side of the gapless arresters 10 are connected to flange sections 2A respectively via copper plates 18B capable of supporting the gapless arresters 10 by themselves. Since the length size of the copper plates 18B is very small and the impedance is also small, each gapless arrester 10 is instantly operated to discharge the surge current even if the surge voltage with a steep wave front infiltrates. A cable corrosionproof layer and an insulating tube 3 can be thereby protected reliably.
