Abstract: Ce convoyeur pneumatique isométrique (10), sans amortisseur ni capot, et à vitesse commandée, ainsi qu'un procédé, permettent le transport de récipients légers (16) en masse ou individuellement et selon une vitesse commandée. Un premier jeu de volets (14) traverse la surface du convoyeur depuis un plenum commun en faisant un angle avec cette surface de façon que l'air traversant ces volets (14) présente un vecteur de force aval d'un premier ordre de grandeur. Un deuxième jeu de volets (14) traverse cette surface du convoyeur depuis le plenum commun en faisant un angle avec cette surface de façon que l'air le traversant présente un vecteur de force amont d'un deuxième ordre de grandeur, inférieur au premier ordre de grandeur, ce qui crée un différentiel de vecteur de force vers l'aval en tout point situé sous le fond de chaque récipient, pour provoquer le déplacement de ces récipients (16) vers l'aval. Une rangée périphérique (30) de volets placés le long de chaque bord de la surface de transport peut être orientée vers l'intérieur pour pousser la masse des récipients vers le centre de la surface de transport en groupe serré, pour procurer une force tournée vers l'aval facilitant le déplacement de cette masse vers l'aval, et pour produire un flux d'air transversal créant une barrière pneumatique à travers laquelle un seul récipient, ou un flux raréfié de récipients doit passer, ce qui limite la vitesse de ce ou ces rares récipients. Ce flux d'air transversal tourné vers l'intérieur crée aussi une dépression sur le bord arrière de ce ou ces rares récipients afin de les maintenir en position verticale.

Abstract: A process for forming a two-layer coating on glass or another substrate involves applying first a layer of light metal fluoride on the substrate and subsequently a layer of a porous metal oxide e.g. silica. The metal fluoride layer may be applied by using the sol-gel technique or by other methods e.g. vacuum deposition. The metal oxide layer is preferably applied by a sol-gel technique, by either a dip coating or spin coating. Each layer is preferably about one quarter-wavelength thick. The refractive index of the first layer is lower than that of the substrate, and the second layer has lower refractive index than the first layer. This dependence minimizes reflection of the coating over a broad wavelength range.
