Abstract: L'invention porte sur un système de tri assurant une précision de tri de premier ordre, même dans des applications de tri à haute capacité telles que le tri de copeaux de bois à haute vitesse. Selon une réalisation, un appareil de tri (10) comprend une table de secouage (12) servant à répartir les matériaux, un analyseur spectrographique (14) servant à identifier les matériaux non acceptables d'un courant de produits, un éjecteur (16) servant à détourner les matériaux non acceptables du courant de produits, un réceptacle de tri (18) à trois zones et un système de recirculation (20) servant à renvoyer, pour un passage supplémentaire dans l'analyseur (14) et l'éjecteur (16), une partie sélectionnée de la masse extraite de la trieuse. Le réceptacle de tri (18) à trois zones divise le courant de produits en une partie acceptable, une partie à rejeter et une partie ambiguë comprenant à la fois des produits acceptables et des matériaux non acceptables. Cette partie ambiguë est retriée de façon à améliorer la précision à des capacités de débit élevées.

Abstract: An apparatus for a pop-up display structure that provides a hub structure that is divided into two sections that are held together by a thumbscrew. The two sections define internal channels in the hub for capturing guide pins attached to the tubes such that the tubes pivot about the guide pins and rotate about the hub through slots in the hub. The thumbscrew provides for removal of tubes from the hub structure without the use of tools and therefore provides for changes on the fly for reconfiguring the structure or for replacing broken tubes. The thumbscrew also provides a mounting structure for the channel bar that attaches to the pop-up structure. The channel bar is capable of folding into three sections and is capable of folding compactly without regard to the sequence of the folds.

Abstract: L'invention concerne un procédé et un système qui permettent de modifier intentionnellement l'accessibilité d'une information codée sur un support optique (1150), de façon à indiquer l'état ou l'historique d'un élément qui lui est associé. Dans l'un des modes de réalisation, la modification du support optique (1150) fait appel à un dispositif (1170) qui permet d'endommager intentionnellement ledit support (1150) lorsqu'on accède pour la première fois à l'information, de façon que lors des tentatives ultérieures pour accéder à ladite information, on puisse détecter l'accès antérieur grâce aux erreurs d'accès générées intentionnellement. La présente invention représente donc une technique efficace pour limiter la duplication et/ou l'utilisation illégale de logiciels, de films et de musique notamment, enregistrés sur des disques compacts et des disques polyvalents numériques. Elle est également utile pour vérifier l'identité des personnes et/ou l'authenticité des cartes de transaction financière durant des transactions financières.

Abstract: A latching device is provided for coupling a vehicle tool carrier with a variety of tools such as a bucket. The device serves to releasably secure the tool with the carrier once the carrier has been positioned with the tool. The latch includes a handle-actuated pawl and an over center linkage to retain the latching device in either its latched or unlatched position. A spring serves to hold the link in its over-center position. The pawl swings laterally to minimize interference with the carrier and tool structures and simplify activation by the operator from his seat.

Everyday, favorite and theme lists may be generated to respectively combine TV channels being watched regularly, favorite TV channels and channels relating to particular subjects. An oval list name object is arranged on a screen to indicate the name of the currently selected list of TV channels. The users may click on the list name object to make their selection among various TV channel lists available in the TV system. In a channel changer mode, the TV GUI displays a graphical channel changer composed of channel boxes that show numbers and logos of TV channels in the currently selected list.      To switch the TV set to a required TV channel, the user clickss on the graphical channel box that indicates the required channe.      In a program guide mode, a list of TV programs may be provided based on the channel changer. Vertical program bars that display TV programs are aligned with the channel boxes indicating TV channels that carry the corresponding TV programs. To identify various TV channel lists available in the TV system, the oval list name object, as well as the channel boxes and program bars, are displayed in a color that represents a selected TV channel list.

Abstract: In a method of manufacturing a polarization-maintaining optical fiber coupler by heating lengthwise portions of two polarization-maintaining optical fibers extending side by side, and elongating the heated portions to thereby form a fused-elongated section, elongation is terminated when the cyclic changes in a coupling ratio of two polarized waves according to an elongation length at a wavelength in use are both within first two cycles, so that the coupling ratio of one of the polarized waves is equal to or less than 10% and the coupling ratio of the other one of the polarized waves is equal to or greater than 90%. This method can provide a polarization-maintaining optical fiber coupler whose coupling ratio has a large dependency on polarization with a short elongation length.

Abstract: An optical illumination system (2) comprising a waveguide (16) that accepts light and transmits the light via total internal reflection. Attached on one face of the waveguide (16) is an array of lenticular microprisms (28), with each microprism (28) having a light input surface (30) optically coupled to the waveguide (16) and a light output surface (32). The light input surface (30) is defined by a number of tapered grooves (34) which prevent light from escaping form the waveguide (16) and further redirect light within the microprism (28). Light that escapes from the waveguide (16), reflects off the tilted sidewalls (36, 38) of the tapered grooves (34) and emerges from the microprism (28) as a spatially directed light source. An array of lenticular microlenses (60) may be positioned to accept the output of the microprisms (28) so that the light exiting from the microlenses (60) is a substantially collimated light source.

Abstract: A continuous Liquid-Solids Circulating Fluidized Bed (LSCFB) preferably for use as an ion exchanger consists of two fluidized bed columns, a fluidized bed adsorber (downer) operating in conventional fluidized bed mode for adsorption of ions of interest and a fluidized bed riser for desorption of ions (operating as a riser fluidized bed) to provide regenerated particles. Ion exchange particles circulate continuously between the riser and the downer i.e. the particles that have adsorbed ions in the absorber pass from the adsorber (downer) to the desorber where they are regenerated and the so regenerated particles are return to the adsorber near the top of the adsorber column. The LSCFB can be used in processes for continuous recovery of the ions of interest.

Abstract: In a vehicle air conditioner where a foot mode and a foot/defroster mode can be set, when a target temperature of air blown into a passenger compartment is higher than a predetermined temperature, the foot mode is selected. However, even if the target temperature of air is higher than the predetermined temperature, the foot/defroster mode is selected in place of the foot mode when an outside air temperature is lower than a predetermined temperature and when a vehicle speed is higher than a predetermined speed. In the vehicle air conditioner, because the foot/defroster mode can be suitably automatically selected based on a fog-generation condition of a windshield, both fog-preventing performance of the windshield and heating performance of the passenger compartment are improved during heating operation.
