  Procédé d'imprégnation pour la conservation de bois de construction, de poteaux de lignes électriques, etc.,. 



   La présente invention a trat à un procédé d'impré- gnation de bois de construction de poteaux de lignes électrique etco, et consiste en ce qu'on introduit un ingrédient d'im- prégnation minéral dans le bois vif encore sur pied donc avant son abattage. On laisse alors l'arbre encore sur plant quelque temps pour assurer la bonne répartition de l'ingré- dient dans le bois. 



   Comme ingrédients minéraux, on peut employer des solutions acqueuses de fluorure de sodium (Na F) ou de nitrochlorophénol de sodium. Ces solutions doivent être introduites dans les cellules des plantes au moyen de fora- ges dirigés obliquement vers le bas et jusqu'au centre des arbres en veillant pendant environ un mois que ces forages restent toujours remplis. 



   L'expérience a démontré que par ce procédé, la so- lution s'introduit avec la sève dans toutes les cellules du bois et pour assurer encore une bonne distribution de l'ingrédient employé, on laisse les arbres encore debout pour quelque temps, après quoi on les abat. On est alors   @

 sûr d'avoir du bois tout à fait imprégné. 



   Il est à noter que le bois résineux exige des solutions plus fortes que le bois feuillu. En général l'imprégnation du bois abattu contre la destruction par des insectes et plantes parasites demande des solutions plus fortes que l'imprégnation pour protéger le bois vert contre les dites attaques. 



   Les ingrédients mentionnés sont introduits en relativement petites quantités dans du bois sur pied. Ils produisent le dépérissement de la plante et font jaunir le feuillage des arbres résigeux déjà au bout d'un mois. On reconnaît à cela que l'ingrédient d'imprégnation a été distribué par la sève de l'arbre dans toutes les parties du bois même dans le coeur de l'arbre. Par ce fait, ces substances assureront une conservation parfaite du bois dans toutes ses parties de la plante. On n'arrivera jamais à ce résultat avec le traitement du bois déjà sec parce que ses parties oléifères et résinifères ne se prêtent pas à une pénétration complète de la solution acqueuse.

   Par une imprégnation selon la présente invention, même des parties de ces plantes qui pourraient avoir déjà commencé à se gâter seront protégées contre tout progrès ultérieur du mal. 



   Ce n'est qu'en solution très faible que les so- lutions employées suivant la présente invention pourraient entrer en considération comme remède contre les insectes nuisibles ou les plantes parasites par exemple pour des ar- bres de parc ou d'allées qu'on   tient   à conserver. Un pareil emploi n'est cependant recommandable que pour des plantes autres que des arbres fruitiers. Pour ces derniers, un empoisonnement des fruits est à craindre. 



   On a déjà proposé des procédés semblables pour combattre des parasites, mais tous ne se prêtaient   pas &   un emploi sur une vaste échelle pour protéger des forêts entières contre des insectes nuisibles, ou c'était le prix   @   

 <Desc/Clms Page number 3> 

 élevé de l'ingrédient, ou la difficulté de sa fabrication en grande quantité qui empêchait son emploi général. 



  D'autre part, les méthodes d'application ne permettaient pas à un seul homme de traiter quelques centaines d'arbres par jour comme c'est possible avec le procédé suivant la présente invention. 



   On pourrait aussi suivant les circonstances ajou- ter aux ingrédients cités des sels ou des oxydes de métaux. 



  La conservation des poteaux des plus grandes dimensions occasionne une dépense d'environ deux kilogrammes. 



   Le but poursuivi par le/ procédé suivant la pré- sente invention n'est donc pas principalement la lute con- tre des plantes parasites ou des insectes nuisibles du bois sur pied, mais avant tout un moyen pour conserver du bois de construction contre la pourriture et les vers. 



    REVENDICATIONS   
1 Procédé d'imprégnation pour la conservation de bois de construction, de poteaux de ligne électrique, etc., caractérisé en ce qu'on introduit un ingrédient d'imprégnation dans le bois encore sur pied avant son abattage en une quantité suffisante pour produire au bout d'un temps limité le désèchement du feuillage en même temps qu'une répartition parfaite de l'ingrédient.

  Impregnation process for the conservation of construction timber, power line poles, etc.,.



   The present invention relates to a process for the impregnation of timber for the construction of poles of electric lines etco, and consists in introducing a mineral impregnating ingredient into the living wood still standing, therefore before its production. slaughter. The tree is then left on the plant for some time to ensure good distribution of the ingredient in the wood.



   As inorganic ingredients, aqueous solutions of sodium fluoride (Na F) or sodium nitrochlorophenol can be used. These solutions should be introduced into the cells of the plants by means of boreholes directed obliquely downwards and to the center of the trees, ensuring for about a month that these boreholes always remain filled.



   Experience has shown that by this process the solution is introduced with the sap into all the cells of the wood and to ensure a good distribution of the ingredient used, the trees are left standing for some time, after what we shoot them. We are then @

 sure to have fully impregnated wood.



   Note that softwood requires stronger solutions than hardwood. In general, the impregnation of felled wood against destruction by insects and parasitic plants requires stronger solutions than impregnation to protect green wood against said attacks.



   The mentioned ingredients are introduced in relatively small quantities into standing timber. They produce the dieback of the plant and cause the foliage of resinous trees to turn yellow already after a month. It is recognized by this that the impregnation ingredient has been distributed by the sap of the tree in all parts of the wood even in the heart of the tree. As a result, these substances will ensure perfect conservation of the wood in all its parts of the plant. This will never be achieved with the treatment of already dry wood because its oleiferous and resinous parts do not lend themselves to complete penetration of the aqueous solution.

   By an impregnation according to the present invention, even parts of these plants which might have already started to spoil will be protected against any further progress of the disease.



   It is only in a very weak solution that the solutions employed according to the present invention could come into consideration as a remedy against harmful insects or parasitic plants, for example for trees in parks or paths which are to be used. would like to keep. Such use, however, is only advisable for plants other than fruit trees. For the latter, fruit poisoning is to be feared.



   Similar methods have been proposed for controlling pests, but not all of them lend themselves to widespread use to protect entire forests against pests, or that was the price.

 of the ingredient, or the difficulty of manufacturing it in large quantities which prevented its general use.



  On the other hand, the application methods did not allow a single man to treat a few hundred trees per day as is possible with the process according to the present invention.



   It would also be possible, depending on the circumstances, to add to the mentioned ingredients salts or oxides of metals.



  The conservation of the poles of the largest dimensions entails an expenditure of approximately two kilograms.



   The aim pursued by the / method according to the present invention is therefore not mainly the control of parasitic plants or insect pests of standing timber, but above all a means of preserving construction timber against rotting. and worms.
