| 20110107941 | COATING MATERIAL FOR ROAD CONSTRUCTION - A mixture designed for coating public roads includes: i) a mineral granulate and ii) a non-bituminous binder that is obtained from raw materials of plant origin. The binder consists of a cellulose compound that belongs to the family of cellulose fatty esters. The melting point of the cellulose compound is advantageously between 60° C. and 250° C., preferably between 120° C. and 180° C. The mixture can include between 1% and 20% of binder in content by weight relative to the material, and preferably between 4% and 10%. A process for preparation of a mixture using the binder is also claimed. | 05-12-2011 |
| 20100182604 | DEVICE FOR OPTOELECTRONIC MEASUREMENT OF THE HYDRATION OF A PLANT IN ITS NATURAL ENVIRONMENT - An optoelectronic device for measuring the water content in a plant element and an apparatus designed to evaluate and monitor in real time the state of hydration of the plant covers. The device includes an optoelectronic probe connected to a measurement module, the probe including: i) a first light source emitting at a wavelength corresponding to a strong water absorption band; ii) optionally, a second light source emitting at a wavelength close to the first source and weakly absorbed by water; and iii) a photo receiver having a spectral response that corresponds to the emission bands of the first light source or of the first and second light sources, the device including elements for modulating the average optical power emitted by the light source or sources at a defined frequency, and elements for synchronously detecting the light received by the photoreceiver. | 07-22-2010 |
| 20100047449 | PROCESS FOR DEPOSITION OF NON-OXIDE CERAMIC COATINGS - A method for depositing a non-oxide ceramic-type coating based on chrome carbides, nitrides or carbonitrides, by DLI-CVD at low temperature and atmospheric pressure on a metallic substrate, includes: a) a solution is prepared, containing a molecular compound which is a precursor of the metal to be deposited, belongs to the bis(arene) family, and has a decomposition temperature of 300° C.-550° C., the compound being dissolved in an oxygen atom depleted solvent; b) the solution is introduced as aerosol into a heated evaporator at a temperature between the solvent boiling temperature and the precursor decomposition temperature; and c) the precursor and the vaporized solvent are driven from the evaporator towards a CVD reactor having cold walls, with a susceptor carrying the substrate to be covered and heated to a temperature higher than the decomposition temperature of the precursor, to a maximum of 550° C., the evaporator and the CVD reactor being at atmospheric pressure. | 02-25-2010 |
