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.

4.WO/1985/004122PROCESS FOR RECOVERING CRUDE OIL OR REFINED PRODUCTS FROM SEDIMENTED, FROM SLUDGY AND THICKENED TO COMPACT CRUDE OIL OR REFINED PRODUCTS, AS WELL AS PLANT FOR IMPLEMENTING SUCH PROCESS

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.

5.WO/1987/002696AMMONIA TREATMENT PLANT AND METHOD

WO - 07.05.1987

Clasificación Internacional B01D 53/14 Nº de solicitud PCT/FR1986/000356 Solicitante L'AIR LIQUIDE, SOCIETE ANONYME POUR L'ETUDE ET L'E Inventor/a BRUGEROLLE, Jean-Renaud

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.

6.WO/1985/000268SUGAR CANE HARVESTER TOPPER

WO - 31.01.1985

Clasificación Internacional A01D 45/10 Nº de solicitud PCT/AU1983/000087 Solicitante MASSEY-FERGUSON (AUSTRALIA) LIMITED Inventor/a QUICK, Donald, Jonathan

A sugar cane harvester topper mechanism capable of severing green sugar cane tops and discharging the severed tops on either side of the harvester. The mechanism has a pair of driven contra-rotating in-running cutters (84, 86), with beveled and scalloped cutting edges. Two rotatably mounted steel cutters (122, 124) with a beveled cutting edge are mounted on the topper. One of the steel cutters bears against the underside of each driven cutter and cooperates with the beveled and scalloped cutting edge to sever cane tops. A deflector is pivotally mounted between the drived cutters to deflect tops selectively towards either of the cutters.
