Abstract: In accordance with the invention, a fixture (10) is provided to receive a label (L) to be applied to a CD disc (13,15). The fixture includes a base (12) having a well (14) of a dimension approximately the shape of the label and CD disc. The label, after printing indicia thereon, is placed adhesive side up in the well of the fixture. Since the well also approximates the shape of the CD disc, the disc may be placed in the well first, within the bounds of the well of the fixture, with its unwritten side facing up. The disc or label is then overlaid on the other manually in the well, and pressed in place, to adhere the label to the disc. A pair of oppositely disposed cutouts are provided in the fixture to enable the composite card and adhered label to be removed from the fixture by inserting the fingers beneath the laminate and lifting it up from the fixture. The sidewalk (16, 18) of the well are rotatable and opposed edges are straight and arcuate so as to present when oriented to the interior of the well, circular or truncated shape to the interior of the well to accommodate different shaped discs.

Title: Dialyzer
Inventor: TUOMINEN OLLI
IPC: A61M1/14
Filed: 2002-07-02
Granted: 2009-09-08
Abstract: A dialyzer design that includes a potting material encasing a microfiber bundle in each end of a cylindrical body. The potting material is set by spinning the dialyzer in a centrifuge to force the potting material to the ends of the dialyzer interior chamber, where it sets with a non- planar surface. Dialysate fluid distribution rings define a space between the dialyzer interior chamber and dialyzer inlet and outlet ports, and laterally support the microfiber bundle against the dialysate fluid flow pressure. The dialysate fluid distribution ring circumferential edge substantially conforms to the non-planar potting material surface, to ensure that the lateral support to the microfiber bundle is constant, thereby lessening distortion, rupturing and obstruction of the microfibers.

Abstract: A system is presented for detecting downhole generated telemetry pressure pulses in a well. The system employs high sensitivity dynamic pressure sensors such as hydrophones for detecting the pulses in either the surface drilling fluid supply line or in the fluid return annulus. The high sensitivity allows detection of smaller surface pulses than standard transducers. In one embodiment, an annular pulser is used to generate pulses directly in the annulus.

Abstract: A system and method implemented in an interactive television system for selectively controlling the verification of interactive television content delivered to a receiver wherein a notification is provided to the receiver to identify content which can be trusted and, when trusted content is delivered to the receiver, verification procedures on the trusted content are inhibited. The notification may be delivered prior to or with the trusted content, and it may be delivered via the same transmission means as the content or by some separate delivery means. The notification may identify the trusted content positively or negatively and may use wildcards in the identification. The trusted content may be identified by its source (e.g., a trusted channel) or by reference to the content itself. The notification may contain an expiration time beyond which is no longer valid. The notification may also contain an identifier and version number so that a subsequent notification having the same identifier and a later version number will supersede the prior notification.

Abstract: This invention relates to a method for producing virus RNA polymerases of RNA viruses, more specifically, virus RNA polymerases of RNA viruses free of virus genomic RNA. The methods described in this invention includes the procedures for preparation of cDNAs for the genes for the component proteins of RNA polymerase of an RNA virus, incorporation of the cDNA into baculovirus genome to construct recombinant virus, and the infection of insect cells with the recombinant virus to express RNA polymerase. In this method, it is recommended that all species of the recombinant viruses, each of which is designed for expressing each of the above--mentioned component protein genes of RNA polymerase, are coinfected into insect cells. Thus, cDNA is prepared for each of the component proteins of RNA polymerase and incorporated into baculovirus genome to construct recombinant virus for independently expressing the corresponding protein. In addition, the RNA viruses described above include influenza virus especially. In this method, RNA polymerase may be tagged to facilitate the subsequent purification. Furthermore, the tagged RNA polymerase described above may be purified using an adsorbent to trap the RNA polymerase at the tag. Another subject matter of this invention is to artificially prepare acomplex of the component proteins of RNA polymerase of an RNA virus, or, in other words, to prepare RNA polymerase free from RNA virus genomic RNA. The RNA viruses described here include influenza virus, and the component proteins of RNA polymerase include PA, PB1 and PB2.

Abstract: Cette invention concerne un système d'imagerie tomographique moléculaire induite par fluorescence qui est conçue pour détecter une activation de la fluorescence dans le proche infrarouge au niveau de tissus profonds. Le système repose sur l'emploi de sondes moléculaires fluorescentes ciblées ou de sondes moléculaires hautement sensibles à fluorescence activable. De telles sondes ajoutent une spécificité moléculaire et produisent un contraste de fluorescence marqué, ce qui favorise une détection précoce et une évaluation de cibles moléculaires sur des tissus malades, tels que des tissus cancéreux, in vivo. Le nouveau système d'imagerie tomographique autorise une localisation tridimensionnelle dans des tissus profonds et une quantification des sondes moléculaires.

Abstract: The present invention relates to a heat exchanger and condensation combustion chamber assembly, comprising a plurality of tubes and including a front plate and a rear plate connected to the combustion chamber with a drop pattern. Each of the heat exchanger tubes comprises a variable area cross section, with a flat portion at a middle region, to provide a larger thermal exchange surface. The middle region is subjected to a crossed cut molding process to provide a helical type of fume path, suitable to enhance the efficiency of the assembly, owing to an increased thermal exchange between the fumes and heated air flows. The combustion having a cross section of drop shape allows to properly solve the problem related to the very high temperatures generated by recent cylindric gas burners having a metal mesh surface generating great amounts of heat, which must be disposed of in a thermal exchange process with the heated air flow.
