Abstract: L'invention se rapporte à un filtre accordable à ondes guidées et à deux points d'accès, fabriqué dans une matière pour substrat opto-acoustique/électro-optique. Ce filtre comporte deux points d'accès triples, des diviseurs de faisceaux à branches en Y symétrique reliés à un point d'accès d'entrée et à un point d'accès de sortie par deux sections de guide d'onde dans lesquelles se produit le couplage de polarisation à concordance de phase. La différence de chemin optique entre les diviseurs de faisceaux est égale à une demi-longueur d'onde optique, et les régions de couplage de polarisation entre les diviseurs de faisceaux sont décalées relativement d'un multiple entier impair de la demi-période spatiale de la perturbation responsable du couplage. Dans une réalisation de filtre accordable électro-optique, le couplage de polarisation dans les guides d'ondes est généré par un film induisant une tension à périodicité spatiale et l'accord résulte de l'application d'un champ électrique. Dans une réalisation de filtre opto-acoustique, le couplage de polarisation est généré par une onde acoustique de surface et l'accord est obtenu par modification de la fréquence acoustique. Il est également possible de former des filtres accordables opto-acoustiques et électro-optiques à quatre points d'accès en remplaçant les diviseurs de faisceaux à point d'accès triple par des coupleurs directionnels à point d'accès quadruple.

Title: Method and apparatus for testing wireless communication channels
Inventor: FISCHEL SCOTT EDUARD
IPC: H04B17/00
Filed: 2001-01-10
Abstract: Techniques to test a wireless communication link. A traffic channel is tested via a test data service option (TDSO) that may be negotiated and connected similar to other services. Test parameters values may be proposed, accepted or rejected, and negotiated. Test data for a channel is generated based on a defined data pattern or a pseudo-random number generator. Sufficient test data may be generated based on the generator for a test interval, stored to a buffer, and thereafter retrieved from a particular section of the buffer to form data block(s) for each "active" frame. The traffic channel may be tested using discontinuous transmission. A two-state Markov chain determines whether or not to transmit test data for each frame. The average frame activity and average burst length are defined by selecting the probabilities for transitioning between the ON/OFF states of the Markov chain, which may be driven by a second generator.

Title: Process for treating a solid-liquid mixture
Inventor: COLLINGS ANTHONY FRANCIS
IPC: A62D101/26
Filed: 2001-09-13
Abstract: A process for treating a solid-liquid mixture by cavitation has been developed to decompose at least some contaminant associated with the solid particles, the contaminant either being adsorbed into the pores of the solid or onto the surface of the solid particles. The process includes the step of subjecting the mixture to cavitation such that a portion of the contaminant is chemically decomposed. Typically the chemical decomposition occurs at the surface of the solid particles, although the process can also occur to some extent within the pores near the surface of the solid material being treated. Typically the cavitation process is an ultrasonic treatment step, although other cavitation processes are applicable, for example high shear mixing. The cavitation effect is capable of achieving physico-chemical changes at the particle surfaces. The localised high temperatures on bubble collapse (as high as 5000K) can decompose contaminant substances such as PCB and other hazardous materials including polybrominated biphenyl (PBB), organochloride and organophosphate compounds, pesticides and the like. One of the advantages of the treatment process is that the decomposition products are quenched quickly to the temperature of the bulk fluid (at, for example, 50oC) which avoids the reformation of the PCB or the formation of undesirable side reaction products such as dioxins.

Abstract: A cheese extruding machine and process for producing pieces of cheese of an exact weight directly from unaged or semi-aged cheese curds of semi-hard and hard cheeses. The cheese extruding machine includes a standard screw-type vacuum filler which receives large blocks of compressed curds, grinds the blocks into pieces, and compresses the curds into an airless, homogenous cheese flow without significantly damaging the curds. The cheese flow is forced through an elongate cheese forming tube of a desired cross-sectional shape for the cheese. A water jacket disposed about a second half of the cheese forming tube chills the periphery of the cheese flow to increase the firmness and maintain the shape of the cheese flow upon extrusion from the cheese forming tube. Frictional engagement between the cheese flow and the cheese forming tube produces back-pressure against the vacuum filler to maintain the cheese flow at a predetermined extrusion pressure and consistent density. A cutting device disposed at the end of the cheese forming tube cuts the extruded cheese flow into the exact weight pieces of cheese based on rate of cheese flow from the vacuum filler.
