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.

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.

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.

Clasificación Internacional B28B 13/02 Nº de solicitud PCT/GB1983/000091 Solicitante BLATCHFORD, William, Michael Inventor/a OLSEN, Randolffa, Rudolph

A dry wall interlocking building block system includes a method of manufacturing moulds for casting building blocks, in which master forms corresponding in shape and size to the required blocks are cast from a cold-pouring compound in collapsible core-boxes, and in which a mould is built up around the master forms (7) by securing the forms to a casting table (8), placing metal liner plates (9) against the sides of the forms, filling the spaces around the liner plates with a similar cold-pouring compound, allowing the compound to set, and withdrawing the forms to leave a plurality of mould cavities. The mould can then be mounted in a block making machine for large scale casting of concrete blocks in the mould cavities. One feature of the preferred mould is that the liner plates are detachable, countersunk bolts (10) having been fitted in holes in the liner plates (9) prior to filling the spaces around the plates. The invention also includes a two-recess building block cast in the above mould.

10.WO/1982/003449PRECOOL/SUBCOOL SYSTEM AND CONDENSER THEREFOR

WO - 14.10.1982

Clasificación Internacional F25B 29/00 Nº de solicitud PCT/US1982/000341 Solicitante HERBERT, Thomas, H. Inventor/a HERBERT, Thomas, H.

The apparatus (10) of the invention includes a precooler (post heater) heat exchanger (24) and a subcooler heat exchanger (26) which are connected in fluid communication with the refrigerant input and output, respectively, of the condenser (16) (evaporator 60) of a heat transfer system (12). A fluid, such as water, is forced through the subcooler heat exchanger (26) and then through the precooler (post heater) heat exchanger (24) to be in a heat exchanging relationship with the refrigerant flowing therethrough. The method of the invention includes the step of regulating the flow rate of the water flowing through the apparatus (10) such that the refrigerant is precooled to approximately its saturated-vapor state and subcooled when the system (12) is operating in a cooling mode and such that the refrigerant is post heated to at least a saturated-vapor state and subcooled when the system (12) is operating in a heating mode.
