Abstract: Remote units (113) that require locating are managed by a queue controller (180) such that the number and location of remote units (113) that are transmitting at increased power at any given time is limited. In particular, a queue controller (180) places identification information for remote units (113) requiring location onto queues (203) associated with base stations supplying reference pilots to the remote units (113). Additionally, identification (ID) information for the remote units (113) requiring location is placed onto queues (203) associated with base stations neighboring the base stations supplying the reference pilot to the remote units (113). The queues (203) operate on a first-in-first-out (FIFO) basis, that output remote unit ID  at periodic intervals. Once all queues (203) have been emptied of the ID of a particular remote unit (113), location takes place for that remote unit (113).

Abstract: An aerosol tilt valve has an integrated molded hollow stem shaft (18) and molded conical stem cup (19). An upper outer circumferential edge of the stem cup normally fully seals, except when the valve is tilted, against a gasket surrounding the stem shaft. The outer lower wall of the stem shaft and the inner wall of the stem cup define an annular space. At least one molded metering orifice below the upper edge of the stem cup extends from the annular space through the stem shaft. The stem shaft is molded with a molded annular recess about the lower shaft end and with the at least one molded metering orifice. The molded stem shaft is inserted in a mold cavity. A lower portion of an annular shield blocks the metering orifice, and together with the mold cavity and lower part of the stem shaft, defines the stem cup shape. The stem cup is molded having an annular projection extending into the annular recess to form a strong and fully integrated stem cup and stem shaft functioning essentially as one piece.

Abstract: The present invention is directed to a method for improving the ash characteristics of a paper wrapper for a smoking article and for improving the ash characteristics of the smoking article itself.      Specifically, it has been unexpectedly discovered that the ash cohesiveness of a paper wrapper is noticeably improved when carbon fibers having an average length less than about 0.75 inches are incorporated into the paper in an amount up to about 60% by weight. Paper wrappers made with carbon fibers in accordance with the present invention have superior ash characteristics in comparison to paper wrappers incorporating only flax or other cellulosic fibers.      Further, the ash cohesiveness of the paper is improved without resulting in the decline in the quality of other ash characteristics.

Abstract: The present invention relates to a method of improving the durability of water-repellent films deposited on the surface of a substrate and to a coated article having water-repellent film of improved durability deposited on the substrate surface. The method includes the steps of simultaneously abrasively and chemically preparing the surface to expose an increased number of bonding sites on the substrate surface by applying a dispersion including an acid solution and an abrasive material to the surface. The dispersion is then removed and the water-repellent film is formed over the prepared surface. The bonding sites react with the water-repellent film to more effectively bond the film to the substrate and thereby improve the durability of the water-repellent film. The abrading material is preferably selected from the group consisting of alumina, ceria, iron oxide, garnet, zirconia, silica, silicon carbide, chromic oxide, pumice and diamond, and the acid solution is preferably selected from the group consisting of solutions of hydrochloric acid, sulfuric acid, tartaric acid, phosphoric acid, hydrobromic acid, nitric acid, acetic acid, trifluoroacetic acid, oxalic acid and citric acid.

Abstract: Appareil servant à traiter de l'eau ou un autre liquide au moyen d'énergie radiante émise par une lampe ultraviolette (90), et comprenant un guide de forme hélicoïdale, afin de guider l'écoulement du liquide d'entrée, ou une rampe hélicoïdale (60), situé au niveau ou à proximité d'une extrémité d'une chambre annulaire allongée entourant la lampe. Ce guide, ou rampe, sert à imprimer une impulsion hélicoïdale au liquide lorsque ce dernier pénètre dans la chambre. Un guide d'écoulement de sortie correspondant, ou une rampe hélicoïdale (70), peut être situé au niveau ou à proximité de l'extrémité opposée de la chambre afin d'imprimer une impulsion hélicoïdale de sortie au liquide sur le point d'être évacué de la chambre. L'écoulement hélicoïdal sert à prolonger la durée d'exposition du liquide à la lumière ultraviolette et augmente, par conséquent la probabilité de destruction de tout type de contaminant biologique contenu dans le liquide. Les guides ou les rampes de forme hélicoïdale permettent d'améliorer la création de cet écoulement lorsque la pression hydraulique disponible est relativement basse.
