  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.

  I3 allows normal insertions to be made without any appreciable resistance to the air flow, thanks to the parabola which guides the air flow *

 This aeoesabire allows the bypass air flow to be adjusted without using dampers or adjusting butterflies which always

  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.

R E V E N D I C A T I O N S Je revendique comme étant de mon invention,l'idée et les moyens d'atténuer fortement l'intensité sonore dans les gaines dérivées en faisant usage d'un accessoire spécial composé d'une dériva- tion dans laquelle coulisse une parabole de réglage, Cet accessiore peut être combiné avec des matériaux absorbants @ destines à recevoir lés ondes sonores réfléchies par la parabole et à les dégrader en chaleur*- @ La paraboleaainsi-un triple but:celui de régler la Quantité' de flux d'air dérivé; CLAIMS I claim as being of my invention, the idea and the means of strongly attenuating the sound intensity in the derived ducts by making use of a special accessory composed of a branch in which slides an adjustment parabola, This accessory can be combined with absorbent materials @ intended to receive the sound waves reflected by the parabola and to degrade them into heat * - @ The parabola thus a threefold purpose: that of regulating the Quantity of the derived air flow; celui de réduire considérablement la quantité d'ondes sonores admises dans'la dérivation et de réfléchir celles- ci de façon à les amortir sur un matériau spéciale Les figures n 1,2 et 3 représentent une des formes que l'on peut donner à cet accessoire,Nous nous réservons de lui donner toute autre forme qui permettrait d'atteindre le même bute that of considerably reducing the quantity of sound waves admitted into the derivation and of reflecting them in such a way as to damp them on a special material Figures n 1, 2 and 3 represent one of the forms that can be given to this accessory, We reserve the right to give it any other shape that would allow it to reach the same end.
