Abstract: La présente invention concerne un filtre à tamis auto-nettoyant pour le mazout qui est couplé à un écoulement continu de mazout et qui comprend une paire de cartouches comportant chacune un tamis filtrant cylindrique à garniture métallique à fils profilés pour le mazout. Une brosse allongée s'étendant sur la longueur du tamis est disposée entre deux parois de délimitation qui s'étendent également sur la longueur du tamis pour former une chambre. Une séparation allongée comportant deux séries d'ouvertures, sert, avec la brosse allongée, à diviser la chambre en deux chambres dans lesquelles les particules sont décollées et délogées. Un drain communique par le fluide avec la sous-chambre de drain. Pendant le nettoyage, le drain est ouvert et le tamis est mis en rotation contre la brosse pour libérer ainsi les contaminants particulaires et une quantité limitée de mazout à l'intérieur des deux sous-chambres où sont décollées et délogées les particules. Les contaminants particulaires et la quantité limitée de mazout traversent ensuite à grande vitesse les ouvertures et pénètrent dans la sous-chambre de drain qui débouche dans le drain. Dans une autre forme de réalisation, un écoulement inversé de mazout filtré peut être utilisé en combinaison avec la brosse allongée pour décoller et déloger les contaminants particulaires du tamis du filtre à mazout. Une autre forme d'utilisation dans laquelle on utilise un écoulement inversé de mazout filtré à des fins de nettoyage est présentée, dans ce cas, un tamis fixe à mazout est placé dans un système qui isole le tamis à mazout de l'écoulement normal de mazout pendant la procédure de nettoyage.

Title: Reversible flex holder for flexible face sign
Inventor: VERRET NORMAND
IPC: G09F1/12
Filed: 2002-05-23
Abstract: The present invention is a reversible single-piece flex holder for retaining a flexible sign face to a sign frame. The flex holder has a latch block and a latch blade movable toward the latch block about a hinge, for clamping the margin of a sign face. A pair of pivot lips are provided on the outside of the flex holder for engagement into a slot in a sign frame. These pivot lips are symmetrical to each other relative to a clamping axis of the flex holder, such that the flex holder is interchangeably mountable to the margin of a flexible sign face. The flex holder also has a stopper lip extending from the latch block and a stopper bulge on the latch blade. The lip and the bulge interfere with each other when the latch blade is reopened to a certain extent to prevent over-stressing the hinge.
