Abstract:
A process of cultivating bivalve molluscs comprising: preparing micro-cultch, by screening particulate matter in the range of 50 to 500 microns, contacting an aqueous culture containing free-swimming bivalve molluscs larvae at the eyed-larvae stage with the said micro-cultch, screening the aqueous culture when at least 20% of the free-swimming larvae have become spat, and growing the screened spat to the seed stage in a culture medium wherein the spat are maintained in suspension.
Abstract:
A process for the thermal destruction of heavy halogenated wastes in a hydrogen/oxygen flame which process comprises passing a mixture of heavy halogenated wastes in the vapour phase and a carrier gas of hydrogen or hydrogen-rich hydrocarbon through burning means provided with gaseous oxygen. Destruction efficiencies of better than 99.999% can be achieved with typical industrial wastes comprising hexachlorobenzene, polychlorinated biphenyls and related compounds.
Abstract:
Process for the synthesis of a compound of formula I (FORMULA) wherein: U and V may be chosen from a range of substituents including hydrogen, halogen, alkyl and alkoxy; R s and R s may be chosen from a range of substituents including hydrogen and alkyl; n is 0, 1 or 2; and W may be chosen from a range of substituents including the group -//c-G which may be a free carboxylic acid or derivative thereof; the process comprising reacting a sulfate ester of formula II, wherein Q is a cation, with a compound of formula III, wherein L is a leaving group (FORMULA) and hydrolysing the sulfate ester formed. Preferably the sulfate ester of formula II is prepared by the oxidation of a phenol of formula IV with a persulfate.

Abstract:
A reduction process for the metallization of the iron content of ferrotitaniferous materials comprising a first reduction step in the range of 600`C to 850`C in an atmosphere of hydrogen so that more than 5% and not more than 50% of the iron content of the ferrotitaniferous material is converted to the metallic state and a second reduction step of heating the product from the first reduction step to at least 950`C in the presence of solid carbonaceous material so that at least 90% of the iron content of the product from the second reduction step is in the metallic state. At least 90% of the iron content of the ferrotitaniferous material is in the trivalent state when it is submitted to the first reduction step.

Date Oct. 28, 1982.Method of growing molluscs, such as oysters, which method comprises placing a bed of discrete oysters in a vessel through which a stream of a culture medium is caused to flow upwardly and wherein the flow rate is sufficient to maintain the oysters in suspension without causing turbulent movement in the bed.
Abstract:
A process of incorporating non-polymeric particulate matter such as magnetic materials, pigments and minerals, into a cross-linked styrene-base polymeric matrix, which process comprises dispersing the non-polymeric particles with a polymeric dispersant in a medium containing one or more vinyl monomers and a crosslinking agent, and adding a polymerization initiator. Typical polymeric dispersants are copolymers, styrenes and tertiary-nitrogen-containing vinyl monomers. Non-polymeric particulate matter incorporated into polymeric beads by this process is resistant to chemical attack and the beads may be used to prepare composite adsorbents or ion exchange resins.
Abstract:
