Abstract: A method of fabricating plastic products with an integrated Lenticular lens material that thermally protects the ink layer and outer lens surfaces of the Lenticular insert. A Lenticular lens material is provided with a Lenticular lens layer with an outer surface of optical ridges (22) and an ink layer (28) bonded to a transparent lens layer (24). A thermal protective substrate (30) comprising opaque flexographic ink is applied to the ink layer. The application of the thermal protective substrate is completed using a coating unit of a lithographic press. A Lenticular insert is formed from the coated Lenticular lens material and the insert is positioned within a mold cavity. The thermal protective substrate insulates the ink layer. Concurrently, the portion of the mold adjacent the insert is cooled to a temperature below the deformation temperature of the optical ridges.

Title: A rare earth zeolite y and the preparation process thereof
Inventor: DU JUN
IPC: C01B39/02
Filed: 2002-04-24
Granted: 2011-01-04
Abstract: The present invention discloses a high stability rare earth zeolite Y with high rare earth and the preparation process thereof, which zeolite has a content of rare earth of 4-15 wt%, a unit cell constant of 2.450-2.458 nm, a differential thermal collapsed temperature of 1000-1056~C, a silica to alumina ratio of 8.3-8.8, and a content of sodium oxide less than 1.0 wt%. Said zeolite is prepared by drying a rare earth-containing zeolite Y, introducing gaseous silicon tetrachloride carried by dry air and reacting at a temperature of 150-600~ C for 10 min to 6 h, then purging with dry air and washing with de-cationized water to remove the soluble by-products. The rare earth zeolite Y  processes high activity and selectivity for cracking the heavy oils, high activity for hydrogen transfer, has good coke selectivity, can effectively increase the yield of light oils, and improve the quality of gasoline and thus can directly serve as an active component for preparing various hydrocarbon cracking catalysts.

Title: Bande-etiquette auto-laminee et procede d'assemblage correspondant
Inventor: RILEY JAMES M
IPC: G09F3/02

Granted: 2007-10-02
Abstract: L'invention concerne une bande-étiquette auto-laminée faisant partie d'un imprimé commercial composé d'une couche de bourre faciale assemblée à une couche de laminage au moyen d'une couche de revêtement d'adhésion/décollage à dessin. Chacune des deux couches est pourvue de lignes de séparation qui sont sensiblement alignées sur la bande-étiquette placée au-dessus de la couche de laminage. L'invention concerne également un nouveau procédé qui permet de séparer la bande-étiquette de l'imprimé, de retourner la bande-étiquette, puis de l'appliquer de nouveau sur la couche de laminage afin de former une matrice dans l'imprimé, la bande-étiquette étant fixée sur la couche de laminage par un adhésif. On peut ensuite séparer la matrice en séparant la couche de laminage le long de sa ligne de séparation de façon à obtenir une bande-étiquette auto-laminée destinée à être appliquée à une languette de marquage d'une chemise de classement ou analogue. Dans un second mode de réalisation, la couche de bourre faciale de l'imprimé commercial à deux couches comprend une première ligne de séparation, légèrement plus épaisse, qui définit une couche factice et une seconde ligne de séparation qui définit une bande-étiquette légèrement plus fine. Les lignes de séparation sont convenablement alignées sur la couche de bourre faciale et une ligne de pliage est disposée entre lesdites lignes de séparation de sorte que, lorsqu'on enlève la couche factice, on découvre une couche adhésive sur laquelle on peut coller la bande-étiquette en pliant l'imprimé sur sa moitié. Dans un troisième mode de réalisation, on décale une bande-étiquette par rapport à la couche de laminage de façon que l'imprimé puisse être plié afin d'aligner la couche de laminage et de l'amener en contact adhésif avec la bande-étiquette et de les aligner toutes deux de façon sûre avant ou après avoir collé la bande-étiquette sur un autre imprimé.

Abstract: A method of answering a query includes deconstructing documents into path Segments (Figure 2). Identical path segments from different documents are arranged contiguously to form a set of partitions, where each partition has identical path segments (figure 3). The structure of a query is then analyzed to find a match with a document (figure 4). Based upon the analysis, a sub-set of partitions is selected for searching. Content from the query is compared to content within the sub-set of partitions to identify matched content. The matched content has associated structural attributes. The matched content structural attributes are compared to the structure of the query to identify an answer to the query.

Title: Liquid crystal display device
Inventor: NAGATA MITSUTOSHI
IPC: G09G3/36
Filed: 2006-01-05
Granted: 2011-07-05
Abstract: A moving image portion that indicates a moving object moving not less than a given movement amount and a still image portion other than the moving image portion are distinguished with respect to a video signal. Video display data for displaying the moving image portion is generated by repeatedly using the same video signal by repetition times based on temperature of a liquid crystal panel. Movement display data for displaying movement positions of the moving image portion is then generated based on a video signal obtained after the video signal used for displaying the moving image portion and is combined with the video display data. This achieves an effect similar to that obtained by decreasing a field frequency and decreases a "tail trail" phenomenon of the moving object. Furthermore, the movement display data enables recognition of the almost actual position of the moving object.

The methods include the steps of exposing contact lenses with a hydration solution comprising about 30 to 70 percent isopropyl alcohol and water. In some embodiments, the hydration solution is maintained at an elevated temperature. Exposure to a first hydration solution causes the ophthalmic lenses to swell to a size larger than their functional size, and exposure to a second ophthalmic solution causes the lenses to shrink back to a functional size.
