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.

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

WO - 23.10.1986

Clasificación Internacional E04C 1/40 Nº de solicitud PCT/BE1986/000012 Solicitante TADDEI, Serge Inventor/a 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.

WO - 26.09.1985

Clasificación Internacional B01F 5/02 Nº de solicitud PCT/EP1985/000090 Solicitante FIPROSA HOLDING Inventor/a MATTER, Rolf

The process for the recovery of residue-mixed crude oil or refinery products derived from crude oil, these residues being essentially comprised of sludgy, thickened crude oil deposited by sedimentation or refinery products extracted from crude oil and deposited by sedimentation in storage or transport containers to form a more or less compact deposition, is characterized in that the residues containing the oil or other refinery products are resuspended or redissolved in the liquid phase by means of the hydrodynamic energy of liquefaction agents, such as crude oil or fractions thereof, which are mainly chemically affined and pressure-reduced in the remaining liquid phase or directly in the residues, respectively in the sediment. The plant provided for implementing such process comprises at least one liquefaction lance (13) which may be introduced into a container (9) with the sediment or the sedimentary material to be released and comprising at least one nozzle (12) arranged thereon, as well as one or a plurality of conduits conducting to the nozzle or nozzles for pumping the chemically affined liquefaction agents.

According to the disclosed method, the ammonia is removed from a gas effluent of the washing treatment by means of a liquid which is essentially comprised of water, the washing liquid is then regenerated by backflow distillation of the gas to be treated, whereafter at least the major part of the regenerated washing liquid is recycled by heat exchange with the washing liquid to be regenerated. Application for the production of CO₂ by treating fumes with ammonia.

5.WO/1996/004350FOAMED DRILLING FLUIDS, THEIR PROCESS FOR PREPARATION AND THE CORRESPONDING DRILLING METHOD

WO - 15.02.1996

Clasificación Internacional C09K 8/38 Nº de solicitud PCT/EP1995/003102 Solicitante SOFITECH N.V. Inventor/a WILLIAMSON, Don

The present invention is directed to an aqueous foamed drilling fluid for drilling well bores into a subterranean formation, comprising water, at least one clay and at least one foaming agent. According to the invention, it further comprises at least one metal hydroxide. The invention further relates to a method for preparing said foamed drilling fluid.

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

WO - 01.09.1994

Clasificación Internacional A61K 9/14 Nº de solicitud PCT/US1994/000378 Solicitante WARNER-LAMBERT COMPANY Inventor/a 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.

7.WO/1998/029638DEEPWATER RISER SYSTEM

WO - 09.07.1998

Clasificación Internacional E21B 17/01 Nº de solicitud PCT/EP1997/007342 Solicitante SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V. Inventor/a BALINT, Stephen, William

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.

8.WO/1985/000332FLEXIBLE BOW SEAL AIR RIDE BOAT HULL

WO - 31.01.1985

Clasificación Internacional B63B 1/38 Nº de solicitud PCT/US1983/001067 Solicitante BURG, Donald, Earl Inventor/a BURG, Donald, Earl

A marine surface vessel with at least one recess (56) that intersects the hull (14) substantially beneath the static waterline thereof, the recess (56) bounded by sidehulls (15, 16), flexible seal member (17) at its forward portion, with bow shaped members at its aft portion (19) and optionally therebetween (18). The flexible seal member (17) is to absorb much of the initial wave impact to improve ride quality. The recess (56) is supplied with pressurized gas to maintain a lift-augmenting gas layer under the hull (14), which is to improve efficiency, speed, load carrying capability and ride quality. Bow shaped members (18, 19) and sidehulls (15, 16) are to provide sure tracking and turning characteristics, proper hull attitude and trim even if the pressurized gas supply is wholly or partially inoperative. In the preferred embodiment, the sidehull keels (22, 23) diverge to allow a smaller seal (17) width forward between the sidehulls (15, 16) to reduce gas leakage forward and provide a smoother ride.

9.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

Clasificación Internacional A23G 9/06 Nº de solicitud PCT/FR1988/000511 Solicitante GOUIN, Gérard Inventor/a 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.
