  • Patent number: 11914184
    Abstract: An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors on the substrate film; and a plurality of top-emitting, bottom-installed light sources provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception via associated outcoupling areas, wherein for each light source of the plurality of light sources there is optically transmissive plastic layer, produced upon the first side of the substrate film, said plastic layer at least laterally surrounding the light source, the substrate film at least having a similar or lower refractive index therewith; and reflector design including at least one material layer, provided at least upon the light source and configured to reflect the light emitted by the light source and incident upon the reflective layer towards the plastic layer.

  • Patent number: 7604794
    Abstract: The present invention relates to an active and selective zeolite catalyst having MTT structure that is useful in skeletal isomerisation of light olefins. The method for the manufacture of the zeolite catalyst having MTT structure comprises the steps of a) preparing of a gel mixture capable of forming crystalline material, and the mixture comprising sources of alkali or alkaline earth metal (M), of an oxide of a trivalent element (X), of an oxide of a tetravalent element (Y), water and a directing agent (R), and the mixture having a composition, in terms of molar ratios, within the given ranges; b) maintaining the mixture under sufficient conditions, including a temperature of from about 100° C. to about 250° C., under dynamic mode of stirring until crystals of the material are formed, recovering the material; and c) removing the directing agent (R) partly or totally with a calcination procedure.

  • Patent number: 6593502
    Abstract: The invention relates to a process for the preparation of polyols having 3 or 4 hydroxyl groups, from an aldehyde and formaldehyde in the presence of water, followed by hydrogenation of the aldolisation product in the presence of a hydrogenation catalyst at an elevated temperature. The aledhyde is obtained by an aldolisation reaction of an aldehyde having at least two &agr;-hydrogen atoms and a formula according to R1CH2CHO, wherein R1 is selected from a group comprising hydrogen, alkyl groups having 1-7 carbon atoms which can have cycloalkyl substituents, cycloalkyl groups, aryl groups and aralkyl groups with 1-7 carbon atoms is the alkyl chain, with formaldehyde in the presence of water in an amount of 20-70 wt %, preferably 40-60 wt % and in the presence of an anion exchange resin. The hydrogenation is preferably carried out in the presence of water.
