Title: Treating filter masses contg. heavy metals - by mixing with molten silicate material, e.g. blast furnace slag, providing prod. for e.g. road making
IPC: C04B18/04
Filed: 1978-06-30
Abstract: A process for treating filter masses obtd. in the purification of chemical cpds. in liq. form, esp. phosphoric acid made by the wet process eg for use in the prodn. of tripolyphosphates, comprises mixing the dried filter masses with a molten silicate material, esp. molten metallurgical slag. The process is useful for treating the prim. and subsequent filter masses obtd. in the prodn. of H3PO4 from phosphate ores and H2SO4, with subsequent purification of the acid to make it suitable for the prodn. of tripolyphosphates. The filter masses contain eg CaSO4, silicates, phosphates and traces of toxic agents such as Ti, Zn, Cd, Mn, V, Pb, U, F, Cu, As, Hg, rare earth metals etc. After treatment, heavy metals and fluoride can no longer be leached out of the material, so that it is environmentally more acceptable. The treated prod. is useful eg as a road making material.

Title: Circuit protection system for electrical distribution cables - protects long cables carrying relatively small normal currents by responding to heat and magnetic fields
IPC: H02H3/08
Filed: 1989-08-25
Abstract: The system is designed to protect a 380 volt, star connected, three-phase distribution cable against short circuits between phases, between phase and neutral and between phase and earth. The system, known as `PRO-TECH-2000', is affected by two effects of a short circuit on the cable, namely, the thermal and magnetic effects. The value of the short circuit current on a long cable depends on the distance of the short from the protected current source. The system therefore has cut-outs which react to the thermal effect of high currents and cut-outs which react to the magnetic effect of smaller currents.
