Patent WO-9520543-A1 (WO)
Inventor: FAIVRE MICHEL
IPC: C02F1/78
Filed: 1995-01-26
Abstract: A unit for treating water by ozonation, including at least one ozonised white water production apparatus and at least one contactor for mixing water to be treated and white water. The ozonised white water production apparatus includes an assembly for pressure-dissolving ozone in a carrier liquid. In a first embodiment suitable for treating large flows, a fraction (typically 5-15 %) of the main fluid flow to be treated is fed to an ozonised white water production vessel then returned to the main flow within a contactor for treating the entire flow. In a second embodiment more suitable for treating comparatively small flows, the total fluid is directly treated in the ozonised white water production vessel.

Abstract: The present invention relates to a process for polymerizing at least one olefin with the aid of a catalyst containing at least one organometallic compound of a transition metal possessing at least one ligand of cyclopentadienyl or substituted cyclopentadienyl type. The polymerization is carried out in gas phase or in suspension in a liquid polymerization medium selected amongst saturated or unsaturated hydrocarbons, in the presence of hydrogen and a polymlerization component selected amongst halogenated hydrocarbons. The combined use of hydrogen and halogenated hydrocarbon in such a polymerization process simultaneously improves the catalyst activity and the molecular weight control of the polymer.

Patent FR-2735492-A1 (FR)
Inventor: ALARIO FABIO
IPC: B01J23/63
Filed: 1995-06-16
Abstract: The electronic computer has a printed circuit board(12) carrying several electronic components (13) carried on support plates (11). A connector (14) at one edge of the computer allows connection to the external devices. The circuit board is enclosed (15) in a synthetic material applied after the components have been assembled. The synthetic material is chosen to have good thermal properties so it cools the electronic components and also to have good mechanical properties, so it provides mechanical protection for the circuit. The enclosure is sealed to isolate the components from the environment. Cooling is aided by forming recesses (16) in the enclosing layer immediately above components, the reduced thickness of material aiding heat removal.
