Title: Album sheet
Inventor: FRIEDERICHSEN CHRISTIAN
IPC: B42F5/00
Filed: 1997-11-04
Abstract: Known album sheets consist of transparent foil sheets onto which foil strips are individually welded, said procedure presenting technological difficulties. Other album sheets in the form of passe-partouts have the disadvantage that the cut-outs for receiving the picture first have to be punched out using highly complex technological processes, which results in large amounts of unusable cardboard waste. The invention aims to provide an album sheet which has a simple design, requires low quantities of material, and can be produced using simple technology and exclusively on the basis of cardboard.   To this end, the upper layer of the album sheet has at least one pair of parallel strips (5), which are joined to the support (1) in the longitudinal direction of the strips (5) and comprise an unjoined area along the edges facing each other. The distance between these longitudinal joined areas is slightly greater than the length, in one direction, of the object (6) to be housed. According to the invention, the strips (5) have the same length as the longitudinal edges of the support (1). In this way the album sheets can be manufactured by a continuous process.

IPC: G02B6/28
Filed: 1997-12-08
Abstract: La présente invention concerne un coupleur à fibres optiques à étirage comprenant une première fibre munie d'un coeur (11) et d'une gaine (12) et une deuxième fibre munie d'un coeur (21), d'une gaine intérieure (22) et d'une gaine extérieure (23). Dans les régions de couplage étirées du dispositif, les régions de couplage (44, 50) des fibres constituent des guides d'ondes présentant des courbes de dispersion qui s'entrecroisent à une longueur d'onde opérationnelle présélectionnée. La ou les gaine(s) de chaque fibre présente(nt) une distribution monotonique décroissante de l'indice de réfraction, lesquelles distributions de l'indice de réfraction diffèrent d'une gaine à l'autre. Le couplage de la lumière d'une fibre à l'autre ne se produit que dans la bande étroite des longueurs d'ondes entourant la longueur d'ondes opérationnelle. Le diamètre extérieur et le diamètre intérieur des fibres peuvent être identiques l'un à l'autre et ils peuvent être identiques au diamètre des fibres optiques ordinaires, ce qui permet de connecter facilement le dispositif à un système optique.
