Clasificación Internacional H01M 4/32 Nº de solicitud PCT/FR1985/000187 Solicitante SOCIETE LES PILES WONDER Inventor/a STIKER, Bernard

Method for producing a positive nickel hydroxide electrode for alkaline batteries, characterized in that it comprises, in combination, two main successive phases: a first phase comprises the deposition on a substrate of a pasty mixture of powder nickel hydroxide which further includes a relatively reduced proportion of a conducting powder and a very small amount of a binder, and the drying and lamination of the pasty mixture on the substrate; and a second phase which comprises the cathodic polarisation, into an electrolyte based on at least a nickel salt, of the substrate thus coated, dried and laminated, and the washing, drying and softening of the electrode which has been subjected to the cathodic polarisation.

2.WO/1985/000413WATER PUMPING DEVICE

WO - 31.01.1985

Clasificación Internacional F03B 17/02 Nº de solicitud PCT/CH1984/000110 Solicitante ANDREOLI, Marcel Inventor/a HOTZ, Paul

The pumping device is intended to pump water at a higher level, current water providing the driving energy. It comprises a container (1) slowly filled with water (W) lifting a float (2) and actuating via a lever system (4, 5, 6) the piston (7) of a pump. When the piston pump (7, 8) has effected one stroke, the container (1) must be emptied. To this effect, a float pipe (10) enabling the discharge of water fills a container (11) opening an emptying valve (15) via a lever system (12, 13, 14). In order to leave the valve open during a certain time lapse, but not permanently, the container (11) has a calibrated discharge opening (11'). Owing to its simple arrangement, the present pumping plant is convenient to be used in developing countries.

Clasificación Internacional G01V 1/42 Nº de solicitud PCT/FR1985/000119 Solicitante SOCIETE NATIONALE ELF AQUITAINE (PRODUCTION) Inventor/a STARON, Philippe

The method is characterized in that it comprises the marking on rod (7) and ground (8, 9) records elementary records corresponding to a same elevation (Z1 or Z4) of the drilling tool (5), the grouping in pairs of said elementary records, and the intercorrelation of said records of the pairs so as to produce, for each pair, a correlated signal representative of the acoustical energy created and of the travel time difference of the waves received by sensors (7, 8, 9) from which the pair of recordings has been obtained. Applications particularly to the determination of the seismic profile of wells.

4.WO/1985/002222IMPROVEMENTS TO BLOCKING HINGES

WO - 23.05.1985

Clasificación Internacional E05D 11/10 Nº de solicitud PCT/FR1984/000251 Solicitante RAUNER, Hans Inventor/a RAUNER, Hans

The clamping of the cylindrical knots of the hinge (1, 2) against the interleaved washer (9) is caused by means of a lever (15) actuating two excentrics (18) articulated to the pivoting axis (5) and acting under a ring (12) freely engaged at the lower end of said axis (5), said lever (15) being applicable against the cylindrical knots of the hinge in the neutral loosening position, or the lever (15) may be spread apart for the blocking operation. The U-shaped lever (15) comprises two parallel wings (18) extended perpendicularly under the ring (12) of the pivoting axis (5) of the hinge and cut out by oblong openings (17) traversed by an articulation axis (13) from the wings (18) to the pivoting axis (5), those openings enabling the lateral displacement and oscillation of the lever (15) so that the wings (18) act as excentrics by their rounded ends.

5.WO/1989/009365METHOD AND APPARATUS FOR STRIPPING VOLATILE ORGANIC COMPOUNDS FROM SOLID MATERIALS

WO - 05.10.1989

Clasificación Internacional B09C 1/06 Nº de solicitud PCT/US1989/001029 Solicitante KEATING ENVIRONMENTAL SERVICE, INC. Inventor/a KEATING, Paul, J., II

Apparatus, and a method for using the apparatus, for stripping solid material containing at least one volatile organic compound (VOC). The apparatus is provided with a dryer (12) having a heat source to heat the VOC-containing material to a first temperature, hot enough to volatilize the VOC, but below the cracking temperature of the VOC. The VOC in the dryer is volatilized to form VOC gases. A means for combusting the VOC gases (e.g. a kiln) (14) heats the VOC gases with excess air to a second temperature, hot enough to destroy the organics in the VOC gases. Simultaneously the combustion means preferably can be used to treat a kiln processable material to form a desired product. The kiln includes means for feeding the kiln processable material to the heating chamber, means (21) for cooling and recovering the desired product, the means (16) for providing heat for the VOC dryer. The apparatus also includes a conduit (15) for conducting the gases containing VOC from the dryer to the kiln.

6.WO/1983/003826ESTER OF CARBOXYLIC CYCLOPROPANE ACID AND OF (S)-CYANO(4-FLUORO-3-PHENOXY PHENYL)METHYLIC ALCOHOL

WO - 10.11.1983

Clasificación Internacional A01N 53/00 Nº de solicitud PCT/FR1983/000080 Solicitante ROUSSEL-UCLAF Inventor/a TESSIER, Jean

1R, cis 2,2-dimethyl 3/Δ Z 3-oxo 3-terbutoxy propenyl-cyclopropane carboxylate of (S)-cyano (4-fluoro 3-phenoxyphenyl)methyl (A), the preparation thereof, its application to combat parasites particularly mites, and compositions containing them.

7.WO/1987/007924BURGLAR-PROOF SHUTTER FOR THE SECURITY OF BUILDING CLOSURES

WO - 30.12.1987

Clasificación Internacional E06B 9/04 Nº de solicitud PCT/FR1986/000209 Solicitante GIRAUD, Claude Inventor/a GIRAUD, Claude

The shutter for the security of building closures comprises an outer wooden boarding (1), an intermediate steel-plated metal sheet (2), an inner wooden frame (3), the assembly being fixed by blind screws (4). The closure is comprised of a flush-mounted espagnolette (5) housed in sealed heads. The protection of the flaps is provided by a mortise joint of the metal parts (7). The security of the edges is provided by means of a corner piece (8) which is fixed by dowelling in the masonry boards and receiving a U-shaped profiled section (9) welded and embedded into the wooden frame (3). The hinges (10) are counter-welded and welded to the intermediate steel-plated metal sheets (2). This method of fabrication of shutters combines both the advantages of aesthetic and heat insulation qualities of wooden shutters with the security of a metal shutter thus designed as well as of the various security devices linked thereto.

8.WO/1995/018268TENSIONED RISER COMPLIANT TOWER

WO - 06.07.1995

Clasificación Internacional E02B 17/02 Nº de solicitud PCT/EP1994/004345 Solicitante SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V. Inventor/a HUETE, David, Armstrong

A tensioned riser deepwater platform suitable for offshore oil and gas applications is disclosed having a foundation (16) secured to the ocean floor, a topside facility above the ocean surface, and a vertically extending tower jacket (12) secured to the foundation and supporting the topside facility. A plurality of substantially vertically extending risers provide fluid communication between the wells and the topside facility. These risers are connected to riser supports near their upper ends and the riser supports provide the pricipal load transfer between the risers and the tower jacket. Thus, the conductor guides and attendant horizontal bracing of conventional deepwater design can be substantially eliminated.
