Il permet surtout de n'admettre dans la dérivation qu'un mini** d'ondes sonores;or celles-ci,en raison de leur longueur d' onde et des dimensions de la parabole,sont réfléchies et étalées sur la paroi de la tuyauterie dérivée,laquelle est tapissée CI* un absorbant phonique qui'dégrade l'énergie sonore en chaleurs d'où résulte une forte aténuation du brait dans la gaine dérivée.

EMI1.1
PATENT OF INVENTION RELATING TO A BYPASS WALL INSTALLATIONS -DE ME BE oonITIoYN3n1 # D'118 The acoeaae which is the subject of the present invention is intended to equip ventilation and air conditioning installations with air. a special adjustment device to be used on the right of the taps instead of the old taps with tangential insertion.
EMI1.2
/, This acceaaeire is grabbed in the main order from a manohon L of any farm, in which slides an adjusting dish 130-linked sleeve this fixed on the main pipe 0 by means of a bouloande flange with the interposition of an elastic seal E or by any other suitable means, The parabolic part is turned towards the air flow and it

penetrates more or less in the main piping so as to # .- 'the "f'wivew a more or less, large part of air towards the branch where it does not find, the advantages of this device are aultipleo * It pers puts in the first place to no longer use ileini3erti = fj tangon- tiellea bulky and unsightly inside * buildings;
I3 allows normal insertions to be made without any appreciable resistance to the air flow, thanks to the parabola which guides the air flow *
EMI1.4
This aeoesabire allows the bypass air flow to be adjusted without using dampers or adjusting butterflies which always

are the cause of disturbances or reaietanoas to the flow (the air *

Above all, it makes it possible to admit in the derivation only a mini ** of sound waves; however these, because of their wavelength and the dimensions of the parabola, are reflected and spread out on the wall of the derivative piping, which is lined with CI * a sound absorber which degrades the sound energy in heat resulting in a strong attenuation of the braid in the derivative sheath.
