Title: Purifying effluent contg. sulphuric acid and iron salts - treating with calcium carbonate and recovering sulphate separately
IPC: C02F/
Filed: 1976-07-05
Granted: 1985-02-18
Abstract: An aq. sulphuric acid soln. contg Fe is treated by (a) adjusting the pH pref. to 1-4.5, by adding calcium carbonate to ppte. calcium sulphate which is sepd., (b) adjusting the pH of the mother liquor to >=4.5 at 50 degrees C after which an oxidising gas is bubbled in; (c) adding calcium carbonate to adjust the pH to >5 and sepg. the insoluble solids. Also solids contg. calcium sulphate are recovered by the above process.

Abstract: An animal-resistant optical fiber cable (20) includes a core (22) which comprises a transmission medium and a sheath system. The sheath system includes an outer jacket (65) and a dielectric armor (40) in the form of a shell. The shell comprises a plurality of longitudinally extending preformed segments (42-42) each being a composite comprising a substrate portion (50) and a layer (52) of a coating material which has a relatively high hardness - especially a diamond film - disposed on an outer surface of the substrate portion. Each of the segments covers less than half of the periphery of the core and, in a preferred embodiment, eight segments are used. Further, the shell segments are stranded helically about the core with at least portions of longitudinal edge surfaces of adjacent segments being in engagement with each other. The shell segments not only provide rodent protection for the cable, but also they provide suitable tensile and compressive strength as well as suitable flexibility and cable bending performance. Further, because the cable in a preferred embodiment has an all-dielectric sheath system, it is inherently lightning, corrosion and EMP resistant.
