Title
(EN) DISPLAY SIGNS
(FR) PANNEAUX D'AFFICHAGE
Abstract
(EN)
A display sign has a flow surface (10) such as the inner face (9) of a viewing panel (2) or front face (4) of a backing panel (3) over which liquid flows. A liquid pump (13, 107, 161) supplies liquid which runs over the flow surface (10) and encounters means (20) such as projecting interruptions (21) for causing irregularities in the transient light effects are created which accentuate a sign element (25). The means for causing flow irregularities may also comprise means (5) for intermittently varying the volume of liquid. The sign element (25) may comprise a part of the flow surface (10) and may be defined by the conformation of the interruptions (21).
(FR)
Le panneau d'affichage décrit comprend une surface d'écoulement (10), qui est constituée par la face intérieure (9) d'une plaque de visualisation (2) ou par la face frontale (4) d'une plaque dorsale (3) et sur laquelle s'écoule un liquide. Une pompe à liquide (13, 107, 161) fournit le liquide qui s'écoule sur la surface d'écoulement (10) et rencontre des organes (20) constitués par exemple par des arêtes saillantes (21) et servant à produire dans les effets lumineux transitoires des irrégularités qui accentuent la luminosité de l'élément affiché (25). Les organes produisant les irrégularités d'écoulement peuvent également comporter des organes (5) destinés à faire varier par intermittence le volume de liquide. L'élément affiché (25) peut comprendre une partie de la surface d'écoulement (10) et peut être défini par la configuration des arêtes (21).
