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

WO - 30.12.1987

国际分类 E06B 9/04 申请号 PCT/FR1986/000209 申请人 GIRAUD, Claude 发明人 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.

2.WO/1986/000758IMPROVEMENTS TO POSITIVE NICKEL HYDROXIDE ELECTRODES FOR ALKALINE BATTERIES

国际分类 E05D 11/10 申请号 PCT/FR1984/000251 申请人 RAUNER, Hans 发明人 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.

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

WO - 05.10.1989

国际分类 B09C 1/06 申请号 PCT/US1989/001029 申请人 KEATING ENVIRONMENTAL SERVICE, INC. 发明人 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.

7.WO/1995/018268TENSIONED RISER COMPLIANT TOWER

WO - 06.07.1995

国际分类 E02B 17/02 申请号 PCT/EP1994/004345 申请人 SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V. 发明人 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.

10.WO/1991/017956PRODUCTION OF ACID SOLUBLE TITANIA

WO - 28.11.1991

国际分类 C01G 23/047 申请号 PCT/AU1990/000217 申请人 WIMMERA INDUSTRIAL MINERALS PTY. LTD. 发明人 HOLLITT, Michael, John

The specification discloses a method of making acid digestible titania. The method comprises the steps of: (1) adding a magnesium or manganese compound to a titaniferous mineral if the content of manganese and magnesium in the mineral is insufficient; (2) heating the mineral in the presence of a reductant for a sufficient length of time and at a sufficiently high temperature to permit the reduction of iron containing compounds to metallic iron and enable titania present to convert to an acid digestible form; (3) cooling the mineral; and (4) separating iron from the mineral by means of an aqueous aeration step. The titaniferous mineral contains insufficient magnesium and manganese if the following expression is not satisfied: (1.98a + 1.14b)/d » 0.08, where a represents the percentage by weight of MgO contained in the mineral, b represents the percentage by weight of MnO contained in the mineral; and d represents the percentage by weight of TiO₂ contained in the mineral. The magnesium or manganese compound is either an oxide or a compound that is capable of converting to an oxide under reaction conditions. An aqueous aeration technique described in the specification involves the use of a sequesterant that is capable of sequestering iron from the mineral without significantly lowering the local pH while at the same time permitting the formation of an oxide of iron at a point away from the mineral. An example of such a sequesterant is citric acid.
