1.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.

3.WO/1999/029441METHOD FOR EXTRACTING DIAMONDS FROM DIAMOND-CONTAINING RAW MATERIALS

WO - 17.06.1999

Clasificación Internacional B03B 1/00 Nº de solicitud PCT/RU1997/000401 Solicitante NEM, Vitaly Vasilievich Inventor/a NEM, Vitaly Vasilievich

The present invention pertains to the mining industry and more precisely relates to methods for extracting diamonds from diamond-containing raw materials. This invention can particularly be used for extracting diamonds from ore in diamond-bearing tubes. This diamond extraction method comprises disintegrating the starting raw material, sorting out the disintegrated raw material according to size classes, performing a first separation of the sorted raw material, disintegrating the middlings thus obtained and applying a finishing treatment. This method is characterised in that all operations are carried out using a dry raw material at negative or positive temperatures so as to prevent condensate formation or humidification of the raw material. The middlings can be disintegrated using planetary grinders for autogenous grinding and/or roller presses.

5.WO/1997/000183VACUUM RESTRAINING SEAT

WO - 03.01.1997

Clasificación Internacional B60N 2/427 Nº de solicitud PCT/GB1995/001383 Solicitante WILLIAMS, Richard Inventor/a WILLIAMS, Richard

A safety seat for a vehicle has a perforated surface(s) and means behind the surface(s) to create a vacuum in the event of an emergency, thus retaining the occupant in the seat. The vacuum can be created by means of a pump sucking air out of a cavity behind the seat surface, or by mechanical means such as levers or springs, suddenly pulling a strong sheet away from close proximity to the perforations adjacent where the occupant contacts the seat, thus creating a vacuum.

6.WO/1999/050582MARINE PIPELAY SYSTEM

WO - 07.10.1999

Clasificación Internacional B63B 35/03 Nº de solicitud PCT/GB1999/001030 Solicitante COFLEXIP STENA OFFSHORE LIMITED Inventor/a SEGUIN, Bruno

A marine pipelay vessel (10) equipped with pipe laying apparatus (12) comprising pipe handling means (40, 41) for moving the pipe (100) into its raised launching position, a pipe connection station (14) for connecting together pipe ends when in the launching position, pipe support means for maintaining the pipe in a raised position (18), a static clamp (58) for releasably securing the upper end of a previously launched pipe, pipe launching means (50) for controllably launching the raised pipe stalk in which the pipe launching means comprises a second mobile clamp (60) adapted to be releasably secured to the pipe (100) such that the second clamp means may be raised and lowered controllably over a predetermined stroke distance between the uppermost and the lowermost stroke position relative to the vessel.

7.WO/1993/006002CONTROLLED-HEAVE FLOATING OIL PLATFORM

WO - 01.04.1993

Controlled-heave floating oil platform comprising a deck (12) and a flotation assembly (14). According to the invention, in order to control platform response to sea movement, the floating assembly (14) comprises a rising and falling compartment (36) open to the sea and connected to a gas reservoir (30; 42) by means of a circulation pipe (46; 50) provided with a restriction (48).

8.WO/1997/000366COMBINATION LOCK

WO - 03.01.1997

Clasificación Internacional G07C 9/00 Nº de solicitud PCT/GB1995/001384 Solicitante WILLIAMS, Richard Inventor/a WILLIAMS, Richard

The users of the combination lock will have the opportunity of choosing their own combination and changing it when the time is right. A black box will be positioned in the car hidden from view from thieves and opportunists. It will be powered by its own battery as back up in case the main electricity supply is disconnected. The black box will store in memory the chosen combination and it will allow a certain amount of attempts in order for the user to choose the correct one before shutting down for a certain period of time. It will prevent anyone from using it until time has lapsed. The black box has different switches in order to change the combination (button, combination, mechanical key). They are positioned on the front of the box.

9.WO/1994/027913VORRICHTUNG ZUM ENTSALZEN VON MEERWASSER

WO - 08.12.1994

Clasificación Internacional B01D 1/16 Nº de solicitud PCT/CH1994/000098 Solicitante KAUFMANN, Willy Inventor/a KAUFMANN, Willy

Das zu entsalzende Meerwasser wird mittels Düsen (3) feinverteilt gegen eine Unterseite (1b) eines plattenförmigen Elementes (1) gespritzt. Das Element (1) ist beispielsweise eine Aluminiumplatte, die einen Wärmeträger bildet und die durch Abdeckgläser (15) hindurch nachführbar der Sonnenstrahlung ausgesetzt ist. Das an der Fläche (1b) aufgespritzte Wasser verteilt sich flächig über das Element (1) und wird durch die in diesem Element gespeicherte Wärme verdunstet. Das verdunstete Wasser gelangt durch einen Ausgang (27) zu einem Kondensator (10) in welchem der Wasserdampf kondensiert wird und schliesslich an einem Ausgang (12) als Süsswasser, beispielsweise zum Bewässern von Grünanlagen zur Verfügung steht. Das zu entsalzende Meerwasser wird vorzugsweise in vorbestimmten Abständen nur wenige Sekunden gegen die Unterseite des Elementes (1) gespritzt. Zum Reinigen des Elementes (1) ist vorgesehen, beispielsweise jede Stunde etwa 1 bis 1,5 Minuten Meerwasser gegen die Unterseite des Elementes (1) zu spritzen und dadurch abgelagertes Salz und Verunreinigungen wegzuspülen.

A material made from small pieces of 'pith', the vegetable matter formed between the fibres surrounding coconuts, and having a size of 0.2-2 mm and a corklike texture. The pieces are coated with a binder and polymerised. The small pieces of pith may then be combined with short and/or long coconut fibres, and/or with finely ground coconut husks. The resulting material is compact, impervious, rot-proof, insect-proof and non-flammable. Densities of around 0.7 kg/dm³ are achieved.
