Abstract: A method for treating soils, in particular water-sensitive dry soils, comprising burying a treatment liquid, optionally loaded with a suspended material into trenches and a device for implementing the method. The device comprises a transportable chassis (2), a reservoir and hollow dispensing tines (1). The dispensing tines comprise a vertical supporting portion (3) which connects the dispensing tines (1) to the chassis and a horizontal share portion (4), including a spike (5) prior to penetrating into the soil, and a rear dispenser (6).

Abstract: The invention concerns a method for treating soils, in particular water-sensitive dry soils, comprising burying a treatment liquid, optionally loaded with a suspended material into trenches and a device for implementing said method.

The dispensing tines comprise a vertical supporting portion (3) which connects said dispensing tines (1) to the chassis and a horizontal share portion (4), including a tipe (5) prior to penetrating into the soil, and a rear dispenser (6).

Abstract: A device for treating a liquid effluent such as pig slurry containing significant quantities of nitrogen and phosphorus, the device including a mixing reactor for contacting the liquid effluent with the basic reagent, provided with an intake for said effluent and another intake for the basic reagent; an ammonia-extracting reactor, connected to the mixing reactor, and a tank for storing the treated liquid effluent derived from the ammonia-extracting reactor.

Abstract: In a heat-insulating device comprising radiation-reflecting elements and a conduction-insulating material, the reflecting elements comprise a large number or reflecting flakes that are inserted into and distributed in the insulating material facing the surface through which the radiation has to be stopped. The said flakes are juxtaposed and partially overlap one another so as to conceal the said surface.

Abstract: The invention relates to a heat insulating piece comprising a transporting duct of a storage enclosure for liquids or gases, and a heat insulating covering.At least one layer of heat insulating material is deposited on the outer surface of the wall of the duct or of the enclosure, and an outer wall is disposed around said layer and is maintained with stiffeners which also reinforce the structure of the piece.
