Granted: 2008-10-14
Abstract: A ball valve assembly having two end bodies selectively detachable from each other with each end body defining a fluid conveying bore is provided. A rotatable ball valve element is disposed within the end bodies and defines a central passage having an axis, with the rotatable ball valve element having an open position in which the central passage is aligned with the fluid conveying bores and a closed position in which the passage is not aligned with the fluid conveying bores. The ball valve assembly also includes a pair of seals, with a seal disposed in each end body and in selective abutting engagement with the rotatable ball valve element. The structure of the rotatable ball valve element is controlled such that the ball valve assembly is assembled with the ball in an open position, thereby substantially eliminating the significant force normally required for assembly of the ball valve assembly.

Title: Refractory material for cement industry kilns and use thereof
Inventor: FAJARDO SOLA PEDRO
IPC: F27D1/00
Filed: 2001-01-26
Granted: 2010-04-06
Abstract: The invention relates to a refractory material for cement industry kilns and the use thereof. The inventive material can be used inside cement industry kilns in order to counteract the thermal and physico-chemical deformation that occur inside the kilns. The inventive composition is based on a combination comprising at least 10% by weight of andalusite (Al2SiO5), at least 10% by weight of silicon carbide (SiC) and at least 5% by weight of clay. Moreover, kaolinite (Al2Si2O5(OH)4) can be used instead of andalusite in equal proportions. The refractory material can be used to line the inside of the cement kilns in the calcination areas (2), in the kiln outlet (6) and in the coolers (7).

Abstract: La présente invention concerne un ensemble cathéter composé d'un cathéter proprement dit et d'un ensemble de conditionnement. Entre l'ensemble de conditionnement et le cathéter, on trouve un joint qui limite le passage d'un liquide entre le premier et le second. Ainsi, le cathéter peut être utilisé sans devoir être complètement retiré de son conditionnement. Pendant la miction, l'ensemble empêche l'urine qui s'écoule par la sortie du cathéter de remonter vers le porteur du cathéter via le conditionnement. Le joint permet d'extraire le cathéter de son conditionnement tout en maintenant l'étanchéité requise. Ainsi, le cathéter peut être inséré et utilisé sans risque de contamination tout en étant partiellement maintenu dans son conditionnement.

Abstract: An apparatus for creating microbubbles of gas in a liquid. A vertical pipe member is adapted to receive a liquid-gas mixture having gas bubbles of larger diameter therein. A series of horizontally-extending apertures are provided to permit the pipe member to expel such liquid-gas mixture radially outwardly from such pipe member. The expelled liquid-gas mixture may contact the sides of a containment vessel. In a refinement of the invention, a specific relationship is further specified between the exit area of the apertures and the interior cross-sectional area of the pipe member, in order to most suitably convert the gas bubbles in such liquid-gas mixture to microbubbles of a desired small size when expelled under pressure from such pipe member via such apertures. A method of converting gas bubbles in such liquid-gas mixture to gas microbubbles is further disclosed.

Abstract: L'invention concerne un élément de sécurité (2) sous forme de composite lamellé, s'utilisant pour authentifier un document (1). Ledit composite lamellé comporte au moins une couche de protection transparente, une couche de vernis transparente et une couche adhésive, la couche de vernis se trouvant entre la couche de protection et la couche adhésive. Une interface se présentant sous forme de couche de réflexion sépare la couche adhésive de la couche de vernis. L'interface est divisée en zones d'un modèle (25) avec des surfaces partielles planes et des structures en relief modelées dans la couche de vernis. Les surfaces partielles planes forment des surfaces de fond (3) et constituent des surfaces spéculaires planes pour la lumière arrivant dans le composite lamellé, alors que les zones à structures en relief d'une profondeur structurale optiquement active prédéterminée constituent des éléments de modèle (4). Les structures en relief des éléments de modèle (4) absorbent la lumière incidente. Dans la lumière réfléchie des surfaces de fond (3) à effet spéculaire, les éléments de modèle sombres (4) forment un contraste marqué et le modèle (25) est bien visible. Le contraste entre les surfaces de fond (3) et les éléments de modèle (4) disparaît dans d'autres directions que celles de la lumière réfléchie, de sorte qu'une photocopieuse restitue les surfaces de fond (3) et les éléments de modèle (4) sous forme de surfaces noires.

Title: Seamless switching between multiple pre-encrypted video files
Inventor: VINCE LAWRENCE D
IPC: H04N7/167
Filed: 2003-06-06
Granted: 2009-01-06
Abstract: In a video on demand (VOD) system, methods and apparatus are provided for seamlessly switching back and forth between two pre-encrypted files having changing encryption keys. Such switching back and forth may be required when a VOD server stores both a "normal" copy of a movie and a "special" copy such as a "trick-play" version for, e.g., fast forward and rewind effects. Instead of using keys with changing parities in both streams, the special stream is encrypted with keys using the same parity (even or odd), while the normal stream is encrypted with one dynamic key (odd or even) and one fixed key (even or odd). Other special streams, such as scene branch streams and alternate angle streams can also be accommodated.
