2.WO/1994/018970COLD/SINUS PREPARATION CONSISTING OF PHENINDAMINE TARTARATE WITH OR WITHOUT THERAPEUTIC AGENTS

WO - 01.09.1994

国际分类 A61K 9/14 申请号 PCT/US1994/000378 申请人 WARNER-LAMBERT COMPANY 发明人 LECH, Stanley

The present invention is an improved pharmaceutical composition useful in the treatment of colds, sinus and allergies comprising an unstable antihistamine such as phenindamine that is stabilized in a non-aqueous, inert carrier system. More specifically, the phenindamine is stabilized in a mineral oil/fumed silica particle matrix which so stabilizes the compound that additional, otherwise reactive drugs such as analgesics, decongestants and expectorants can be incorporated for a more effective, multi-system formula.

A deepwater riser assembly (10) for application at an offshore platform comprising: a riser (20) connecting subsea equipment to a surface wellhead; a buoyancy can assembly (30), comprising: an open-ended buoyancy can tube (32) surrounding the upper part end of the riser; a seal (62) arranged in an upper part of the buoyancy can tube so as to effectively close the annulus between the riser and the buoyancy can tube; and a load transfer connection (64B) between the buoyancy can tube and the riser; a pressure charging system (72) communicating with said annulus between the riser and the buoyancy can tube at a location below the seal.

4.WO/1989/012401PROCESS FOR MANUFACTURING FROZEN PRODUCTS, SUCH AS ICECREAM, ICES OR WATER ICES, AND SAID PRODUCTS OBTAINED BY THIS PROCESS

WO - 28.12.1989

国际分类 A23G 9/06 申请号 PCT/FR1988/000511 申请人 GOUIN, Gérard 发明人 GOUIN, Gérard

Said process for the manufacture of frozen products, such as icecreams, ices or water ices, using a raw material corresponding to the desired frozen product is characterized in that a cold-producing fluid is incorporated in a physical form capable of releasing frigories to said raw material until a frozen product of a pasty consistency is obtained; the following step is preferably freezing to obtain said frozen products in a frozen form with a view to their normal storage in conventional freezers, pending consumption. It is thus possible to obtain frozen products, such as icecream, ices or water ices essentially without ice crystals which have improved creaminess.

5.WO/1999/022983ROV INSTALLED SUCTION PILES

WO - 14.05.1999

国际分类 B63B 21/22 申请号 PCT/EP1998/007012 申请人 SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V. 发明人 VON EBERSTEIN, William, Henry

A suction pile anchor system for anchoring offshore structures to the seabed is provided. The system includes a suction pile (10) having an upper end part provided with a pump valve for water to flow between the interior of the suction pile and the exterior thereof, and an ROV provided with pumping means connectable to the pump valve of the suction pile (10) and operable so as to induce water to flow between the interior of the suction pile and the exterior thereof.

6.WO/1992/016637BIOLOGICAL CONTROL AGENTS

WO - 01.10.1992

国际分类 A01N 63/00 申请号 PCT/GB1992/000501 申请人 ROUSSEL-UCLAF 发明人 CAYLEY, Patricia, Jane

A recombinant baculovirus which, in insect cells infected therewith, expresses a foreign protein comprising an insecticidal toxin, or a functional derivative thereof, provided with a signal peptide such that the toxin or derivative thereof is secreted from the insect cells. This recombinant baculovirus can be used in insect control.

7.WO/1989/008615OZONE EMITTER DEVICE FOR EXISTING WATER FILTERING INSTALLATIONS OF SWIMMING POOLS

WO - 21.09.1989

国际分类 C01B 13/10 申请号 PCT/FR1989/000117 申请人 RIEFFEL, Serge 发明人 RIEFFEL, Serge

The device described consists in the combination of an upstream-mounted ozone emitter (13), of an independent air filter (11) and of a flowmeter (12) and, downstream, of a non-return valve (14) with filter (6), and also of a venturi (15) fitted with a valve for controlling the depression, located on the return line (21), upstream of the pump, and finally of a pipeline (5) with filters (18, 19) installed between the upper part (4) and the bases of the main filter, with a possible branch line for cooling of the ozone emitter. In the event that filtering occurs essentially above the water level of the swimming pool, the non-return valve (14) and the venturi (15) may be discarded, the connection of the ozone being made to the pre-filter plug (10), or directly to the pipeline (1) upstream of the pump (9). Said device is designed to permit the installation of an ozone emitter for sterilizing the water of swimming pools, in particular pools with a reduced water capacity, enabling the existing filtering elements to be retained.

8.WO/1988/009875TRAVELLING BARREL DOWNHOLE PUMP HAVING A GAS RELEASE PROBE

WO - 15.12.1988

国际分类 E21B 43/38 申请号 PCT/US1987/001344 申请人 TRIANGLE TRADING CORPORATION 发明人 JONES, William, A.

A downhole pump (10) having a gas release probe (31) which probe can be easily applied to a conventional travelling barrel (12) downhole pump by merely lengthening such barrel by providing a variable length spacing sleeve (86) above the travelling valve. The solid rod (32) of the probe lifts off the valve element of the valve from its valve seat to release any gas or foamy oil otherwise trapped between the lower standing valve and the upper travelling valve of the pump. The invention is useful for obtaining oil under subterranean formation conditions that do not normally permit such recovery efficiently due to gas locks and can be either provided in a downhole pump or added to a preexisting pump. The term variable length spacing sleeve is used to describe a spacing sleeve whose length is established to suit a particular operating environment, and which length is determinable by one skilled in the art after considering the various operating parameters of the oil well in question.

9.WO/1989/012461ANTAGONISTS OF VIRAL TRANSACTIVATING PROTEINS

WO - 28.12.1989

国际分类 C07K 14/025 申请号 PCT/US1989/002404 申请人 ST. LOUIS UNIVERSITY 发明人 GREEN, Maurice

A method for preparing antagonists of viral transactivating proteins is disclosed. In one aspect the method involves the preparation of antagonists from active domains of the viral transactivating protein. Pharmaceutical compositions comprising the antagonists which compositions are useful in treating an individual suffering from viral infection are also disclosed.

10.WO/1988/004343DEVICE FOR THE ASSEMBLY OR MECHANICAL REINFORCEMENT AND THE ANTICORROSION TREATMENT OF IMMERSED STRUCTURE ELEMENTS AND RELATED TREATMENT AND ASSEMBLY METHOD
