Inventor: ERNEST FREDERICK R
IPC: B32B7/12
Filed: 1997-10-16
Granted: 2007-07-31
Abstract: An adhesive is applied to a material under compression such that the adhesive penetrates the material when the material is a porous material (e.g., a fiberglass batt). Upon release from being compressed, the material returns to nearly its original size and shape and some of the adhesive penetrates into the material a given distance. Many mats of the material bearing the adhesive at selected locations can be placed on a common carrier for easy dispensing using a dispenser. The common carrier can be refurbished for reuse.

Granted: 2001-09-25
Abstract: A semiconductor laser light source includes: a semiconductor laser array which emits laser beams whose polarization planes are parallel to each other and whose divergent angles .theta.z and .theta.x in two orthogonal directions satisfy an inequality .theta.z > .theta.x; a cylindrical lens which converges the laser beams emitted from the semiconductor laser array in a direction that decreases the divergent angle .theta.z; a wave plate which controls the direction of polarization so that the polarization planes of the laser beams having passed through the cylindrical lens are at 90 degrees to each other; a birefringent optical element which merges by the birefringent effect the optical paths of the laser beams having passed through the wave plate; and a light emitting surface which converges the laser beams merged by the birefringent optical element in a direction that decreases the divergent angle .theta.x.    Thus, the efficiency of merging the laser beams and the efficiency of joining the laser beams to the succeeding optical system can be greatly improved.

Abstract: L'invention porte sur un procédé et un enregistreur d'événement à décalage temporel pouvant enregistrer des portions d'un signal séquentiel temporel représentant un événement de sorte qu'une représentation d'événement puisse être générée par décalage temporel. A tout moment, l'utilisateur peut entrer une commande de pause d'affichage, ce qui produit l'enregistrement d'une première partie du signal séquentiel temporel à enregistrer. Lorsque l'utilisateur souhaite revenir à la visualisation d'un programme, on reproduit une commande de reprise en enregistrant simultanément une seconde partie enregistrée. Un dispositif d'auto-édition peut utiliser les capacités de reproduction de l'enregistreur d'événements à décalage temporel de l'invention pour générer une bande vidéo (50) contenant un événement enregistré qui a été automatiquement édité. Lors de l'enregistrement d'un événement au moyen, par exemple, d'une caméra vidéo (64), l'opérateur sélectionne des parties de l'événement enregistré qui sont à réenregistrer dans une version éditée. Au cours d'un processus de post édition, seules les parties sélectionnées déterminées sont réenregistrées dans la version éditée.

Title: Method for making hydrophobic organosilicate-modified silica gels under neutral conditions
Inventor: BURNS GARY T
IPC: C01B33/159
Filed: 1998-02-18
Granted: 2007-07-03
Abstract: The present invention is hydrophobic organosilicate-modified silica gels and a method for their preparation under neutral conditions.  The method comprises two steps, where in the first step the pH of an organosilicate-modified silica hydrosol is adjusted with a base to within a range of pH 3 to pH 7 to facilitate formation of an organosilicate-modified silica hydrogel. In the second step, the organosilicate-modified silica hydrogel is contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to effect hydrophobing of the organosilicate-modified silica hydrogel to form a hydrophobic organosilicate-modified silica gel having a surface area within a range of 100 m2/g to 850 m2/g in the dry state. In a preferred process, the hydrophobic organosilicate-modified silica hydrogel is contacted with a sufficient quantity of a water-immiscible organic solvent to convert the hydrophobic organosilicate-modified silica hydrogel into a hydrophobic organosilicate-modified silica organogel. A water soluble compound of cerium or iron may be added in the second step to improve the heat stability of the hydrophobic organosilicate-modified silica gel.

Title: Coin discrimination apparatus and method
Inventor: PARTLOW JOHN
IPC: G07D11/00
Filed: 1998-06-26
Granted: 2007-06-19
Abstract: A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel (52), are singulated by a coin pickup assembly configured to reduce jamming. A coin rail (56) assists in providing separation between coins as they travel past a sensor (58). The sensor (58) provides an oscillating electromagnetic field generated on a single sensing core (212). The oscillating electromagnetic field is composed of one or more frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties. All frequency components of the magnetic field are phase-locked to a common reference frequency. The phase relationships between the various frequencies are fixed, and the interaction of each frequency component with the coins can be accurately determined without the need for complicated electrical filters.

Abstract: Psoralen compound compositions are synthesized which have primary amino substitutions on the 3-, 4-, 5-, and 8-positions of the psoralen, which yet permit their binding to nucleic acid of pathogens.  Reaction conditions that photoactivate these psoralens result in the inactivation of pathogens which contain nucleic acid. The compounds show similar activity in test systems to 4' and 5' derivatives of psoralen useful for inactivation of pathogens in blood products. In addition to the psoralen compositions, the invention contemplates such inactivating methods using the new psoralens.
