1.WO/1983/002950DRILLING FLUIDS AND METHODS OF USING THEM

WO - 01.09.1983

国际分类 C09K 8/36 申请号 PCT/GB1983/000050 申请人 JACHNIK, Richard, Pawel 发明人 JACHNIK, Richard, Pawel

Oil based drilling fluids in which the oil of the oil base is substantially non-toxic to marin life include, as gelling agent, a hectorite gelling agent such as dimethyldioctadecyl ammonium hectorite. The fluids are of particular value for carrying out of a subsea bore hole debris that is to be dumped in the sea while contaminated with the oil.

2.WO/1985/000306PROCESS FOR RECOVERING MINERALS AND METALS BY OLEOPHILIC ADHESION

WO - 31.01.1985

国际分类 B03B 1/04 申请号 PCT/US1984/000946 申请人 OLEOPHILIC SIEVE DEVELOPMENT OF AMERICA, INC. 发明人 KRUYER, Jan

A mixture containing oleophilic surfaced mineral particles and oleophobic gangue particles in an aqueous phase is separated by means of an apertured oleophilic endless sieve (5) supported in a separating zone (11) by a revolving cylindrical cage (1) having apertured sidewalls (2) and supported in a recovery zone (19) by a support roller, each section of sieve surface alternately revolves through the separation zone (11) and recovery zone (19). The aqueous mixture is introduced as a slurry into the rotating cage (1) in the separation zone (11). The endless sieve (5) partly covers the outside surface of the cylindrical cage sidewall (2). An oleophilic adhesive is placed on the sieve as a coating or added to the aqueous slurry in the cage or both. The adhesive attracts the oleophilic mineral particles. The mixture tumbles inside of the cage (1) and thereby is brought up to sieve speed and passes through the cage sidewall apertures (37) to the sieve surface. Aqueous phase of the mixture passes through the sieve apertures (38) into a bath (7) from where it is removed. The oleophilic mineral particles of the mixture adhere to the oleophilic adhesive and are captured by the sieve (5) upon contact and conveyed out of the separation zone (11). Some residual aqueous phase is removed from the sieve (5) after which it passes into the recovery zone (19) where the mineral particles and some adhesive are removed from the sieve (5) as a mixture.

3.WO/1986/005420DRY MATERIAL SORTING DEVICE

WO - 25.09.1986

国际分类 B07B 1/46 申请号 PCT/US1985/000478 申请人 VICKERY, James, D. 发明人 VICKERY, James, D.

A dry material sorting device for selectively sorting mixtures of granular material comprising component materials such as sand and gold having different specific gravities. In a first embodiment, a prescreening device (120) is used to segregate particles into separate batches based on particle size. Each batch is then fed to a horizontal wind tunnel (12) whereby the heavier particles drop out of the air stream nearer the feed point than the lighter particles, thus effecting separation based on specific gravities. In an alternate mode, the screening takes place using a dynamic screen (90) having variable aperture sizes, after the particles have been separated by specific gravities in the wind tunnel (12).

5.WO/1987/004726PROCESS FOR PURIFYING RECOMBINANT PROTEINS, AND PRODUCTS THEREOF

WO - 13.08.1987

国际分类 C07K 1/113 申请号 PCT/US1987/000223 申请人 CAMBRIDGE BIOSCIENCE CORPORATION 发明人 HUNG, Chung-Ho

Process for recovering recombinant protein from refractile inclusion bodies of microorganisms which comprises disrupting cells, recovering refractile bodies containing recombinant protein, solubilizing the refractile bodies with a denaturant, protecting sulfhydryl groups of recombinant proteins, converting cationic amino groups of recombinant proteins to anionic carboxylic acid by derivatization with organic cyclic acid anhydrides, and recovering recombinant protein derivatives. The present invention also relates to the production of solid supports coated with recombinant protein recovered by the process of the invention, and the use of said devices for the detection and quantification of antibodies to said recombinant proteins in body fluids.

6.WO/1986/006126BLOCK MADE OF HYPER-PRESSED DOUBLE COMPRESSED AND COLD-STABILIZED EARTH FOR JOINTLESS CONSTRUCTION

WO - 23.10.1986

国际分类 E04C 1/40 申请号 PCT/BE1986/000012 申请人 TADDEI, Serge 发明人 TADDEI, Serge

Self-nesting hollow block made of hyper-pressed double compressed cold-stabilized earth, enabling the construction of jointless walls and of which the stability is provided by the vertical injection at its centre (1) and on both its extremities (2) and the horizontal injection (5-6) of liquid earth-cement mortar. Due to its multiple shapes - four -, said block enables the construction of a house which is entirely made of earth without using formwork, irons, stays or other materials, eliminates rough casting outside and inside, thereby resulting in important savings in cement and labour.

7.WO/1985/002383DEVICE FOR AUTOMATICALLY ADJUSTING THE PROPELLER PITCH

WO - 06.06.1985

国际分类 B64C 11/34 申请号 PCT/FR1984/000272 申请人 JOULIA, Pierre 发明人 JOULIA, Pierre

The device adjusts automatically the rotor propeller pitch by the action of the centrifugal force on each blade (14) against the predetermined action of a spring member (7). The blade (14) may be displaced axially in a housing (13) of a blade foot (2), said axial displacement inducing a rotation of the blade (14) about its axis to modify the incidence thereof through a screw (3) and a nut (4), one being integral with the blade foot (2) and the other one with the rotor shaft (0). In an extreme position, the device enables the automatic feathering of the propeller. The invention may be conveniently used in aviation and in wind turbines.

8.WO/1982/001888PYROLYSIS PROCESS AND SYSTEM UTILIZING PYROLYTIC OIL RECYCLE

WO - 10.06.1982

国际分类 C10B 53/02 申请号 PCT/US1981/001615 申请人 AMERICAN CAN COMPANY 发明人 BOWEN, Mack, D.

A pyrolysis process and system produces a solid residue and a clean, enriched fuel gas. In the process, the pyrolytic oil and filter cake are recycled in such a manner as to produce products of optimal value, and to minimize the need for servicing and downtime of the system. Recycling of water recovered in the process may also be employed to achieve enrichment of the gaseous product. The process may be carried out in such a manner as to produce a non-polluting wastewater stream that can be discharged directly from the system. The system comprises pyrolysis reactor (10), the off-gases from which are cleaned in scrubber-condenser (12) with recycled oil product. The contaminated oil in (12) is passed through filter (16). The resulting filter cake is recycled to reactor (10), and the filtered oil is recycled as above or stored for later use. The contaminated water from scrubber-condenser (12) is ultimately used to quench the char produced in reactor (10).

WO - 01.09.1983

国际分类 C09K 8/36 申请号 PCT/GB1983/000049 申请人 JACHNIK, Richard, Pawel 发明人 JACHNIK, Richard, Pawel

The oil component of an oil based drilling fluid that is used for carrying out of a subsea bore hole debris that may then be dumped in the sea while still contaminated with the oil is a mineral oil that is substantially non-toxic to marine life and that is of low viscosity at 40oC and at lower temperatures.

10.WO/1989/006737A DRILLING TOOL

WO - 27.07.1989

国际分类 E21B 17/02 申请号 PCT/GB1989/000019 申请人 THE RED BARON (OIL TOOLS RENTAL) LIMITED 发明人 LAU, Werner

A tool is intended for use in an oil or gas well to retrieve a drilling or production string from the well, particularly in a situation where the casing or formation has collapsed, thus gripping the drilling or production string. The tool has a driven member (63) which presents, at its lower end, a self-tapping thread (65) such as a counterclockwise self-tapping thread. The tool includes a ratcheting arrangement (48, 56) which can drive the driven member (63) in a counter-clockwise direction when the tool is lowered relative to the driven member. The tool can be repeatedly raised and lowered thus enabling the self-tapping thread to be engaged with the top of the drilling or production string.
