  • Publication number: 20100172121
    Abstract: The invention relates to a self-supporting luminescent film (10), a phosphor-enhanced illumination system and to a method of manufacturing the self-supporting luminescent film. The self-supporting luminescent film comprises luminescent particles (20) and an organic polymer (30). The luminescent particles comprise luminescent material which is arranged for absorbing at least part of the impinging light impinging on the luminescent particles and for converting the absorbed light into converted light. The converted light has a predefined spectrum different from the impinging light. The organic polymer interconnects the luminescent particles to form the self-supporting luminescent film, wherein the self-supporting luminescent film comprises less than 10 weight percentage of organic polymer. The effect of the measures according to the invention is that the close packing of the luminescent particles generates a substantially uniform self-supporting luminescent film.

  • Publication number: 20100166932
    Abstract: A method for making asymmetrical snack pieces that can be efficiently nested or stacked. A dough preform is mated with a mold as the preform is cooked into a snack piece. The preform takes the shape of the mold. The mold is designed such that the resultant snack piece, when resting upon a flat surface, has an apex and a base of equal height. This is achieved by making the mold such that the centroid of the snack piece lies in a plane that is parallel to a plane formed by the vertices of the snack piece. The snack pieces can then be efficiently nested or stacked.

  • Patent number: 7731878
    Abstract: A process of forming a microperforated plastic film includes providing a post tool having multiple posts, bringing plastic into contact with the post tool such that the plastic conforms to the shape of the posts, and solidifying the plastic into a solidified plastic film having a plurality of microperforations in the shape of the posts. Another step in the process is displacing any skins formed over the holes after solidifying the plastic. The process may be used to form a film for sound absorption where the posts are shaped and arranged to provide microperforations that provide a particular sound absorption spectrum. In one embodiment, the microperforations each have a narrowest diameter of 20 mils, a narrowest diameter less than a film thickness, and a widest diameter greater than narrowest diameter. The widest diameter may be about 125% or more of the narrowest diameter in an embodiment.

Oppositely rotating rollers of tapered diameters are disposed side by side to receive the extrudate therebetween, the rollers arranged so their longitudinal axes intersect and their smaller diameters are oriented towards the downstream end of the die. Extrudate passing through the opening is characterized by a higher flow rate proximate the upstream end thereof to thereby form a radiused extrusion. The rollers draw the extrudate from the die outlet opening without significantly altering the radiused shape of the fluid plastic material.
