Title: Aquacultural structure which can be submerged in the open sea
Inventor: ABEL BELBATI
IPC: A01K61/60
Filed: 1992-02-19
Abstract: The invention relates to an off-shore fish farming structure with useful volume of 700 m<3> (Fig. no.1) and its immersion/emersion device. The immersion/emersion device consists of a floatation system (assembly of tubular modules linked together by flanges) secured to the assembly ( beta ), and of two ascending parachutes ( delta ) (Fig. no.1). After adjusting the volumes of air in the ascending parachutes ( delta ) (by use of a set of valves), and in the compartments of the flotation system (confined-air compartment with constant volume), it suffices to operate the single valve (23) integral with the buoy of the narghile ( alpha ) (Fig. no.1) in order for emersion to take place (by injection of air with the aid of a compressor or diving bottles) or immersion (by opening the valve (23), the air then evacuating the ballasts). The rigid "skeleton", and the width of the space formed over the periphery of the usable volume (net with fish) makes it possible to stretch an anti-diver protection "net" and to protect the livestock from the risks of squashing due to folding of the net during strong submarine currents or violent storms which strike the assembly ( beta ) at unprotected depths.

Title: Treating surface water contaminated with organic matter and micro-pollutants - by adding hydrogen peroxide and ferrous salt
Inventor: HERVE PAILLARD
IPC: C02F1/52
Filed: 1992-04-03
Abstract: Surface water contaminated with organic matter and organic micro-pollutants is treated by peroxido-coagulation involving radical oxidn. by addn. of H2O2 and a ferrous salt under conditions allowing of coagulation of the organic matter and of oxidn. of the organic micro-pollutants. The amts. of H2O2 and ferrous salt are such as to give a molar ratio of H2O2:Fe++ of 0.5-2.0. At least part of the H2O2 is added first, followed by the ferrous salt. Peroxido-coagulation is at pH at least 4.5 (5-6), according to the degree of mineralisation of the water, to reduce the inhibiting effect of carbonates in the water. In later steps, the residual H2O2 is destroyed by treatment with active C or ozonisation, and the pH is brought to 7-8.5, close to the calcocarbonic equilibrium, to render the water potable. The amt. of ferrous salt used is such as to give a ratio of Fe++:organic matter of at least 2 g Fe++/g of total organic C (TOC). USE - Application is esp. to water with a low mineral content, to render it drinkable. Esp., the organic matter is formed by humic substances, and the micro-pollutants by pesticides, chlorinated solvents, phenols and hydrocarbons (claimed).

Title: Preventing the crosslinking of poly:chloro-phosphazene(s) by water - by treatment with thionyl chloride
Inventor: ROGER DE JAEGER
IPC: C01B21/098
Filed: 1992-10-15
Abstract: A process for combatting the crosslinking of poly-dichloro-phosphazenes (I) by water comprises treating the (I) with a thionyl chloride SOCl2.
