Abstract: A process for attaching a substance, especially an organic substance, onto one or more microparticles is provided. The process involves providing a quantity of a substance to be attached onto the microparticles, as well as a quantity of microparticles. The organic substance is then directed through a first conduit (12, 206) and the microparticles are sent through a second conduit (16, 212). The first (12, 206) and second (16, 212) conduits meet at a confluence point (26, 214, 305), and it is there that the substance and the microparticles mix such that the substance attaches to, and coats the microparticles. In a preferred embodiment, there is further provided mixing means such as an in-line static mixer (22, 216, 238, 307, 317, 323, 329) for mixing together the substance and the microparticles. The coated microparticles can be utilized in all manners of immunoassay, nucleic acid assay, cell assay and therapeutic injectable applications. The microparticles herein may also be replaced with another organic substance for conjugation or attachment to the first organic substance.

Abstract: The present invention provides systems and methods for electronic commerce including secure transaction management and electronic rights protection.  Electronic appliances such as computers employed in accordance with the present invention help to ensure that information is accessed and used only in authorized ways, and maintain the integrity, availability, and/or confidentiality of the information. Secure subsystems used with such electronic appliances provide a distributed virtual distribution environment (VDE) that may enforce a secure chain of handling and control, for example, to control and/or meter or otherwise monitor use of electronically stored or disseminated information. Such a virtual distribution environment may be used to protect rights of various participants in electronic commerce and other electronic or electronic-facilitated transactions. Secure distributed and other operating system environments and architectures, employing, for example, secure semiconductor processing arrangements that may establish secure, protected environments at each node. These techniques may be used to support an end-to-end electronic information distribution capability that may be used, for example, utilizing the "electronic highway".

Title: Dispensing pump lock
Inventor: D AMELIO MICHAEL JOSEPH
IPC: B05B11/00
Filed: 1997-10-06
Abstract: Disclosed is a locking assembly for use with a pump-type dispenser (10) to dispense material from a container (14). The assembly includes an actuator (12) including at least one tooth (22) integral to the actuator (12) and a support ring (18) which slidably engages the actuator (12). The support ring (18) has at least one integral circumferential ridge (24, 26) with at least one ridge slot (28, 30).

Patent CA-2277117-A1 (CA)
Inventor: CORDELL ROBERT ROGER
IPC: H04Q11/00
Filed: 1998-01-06
Abstract: Cette invention se rapporte à un élément d'interconnexion assurant la permutation de longueurs d'onde et conçu pour un système de communication optique à multiplexage par répartition en longueur d'onde (WDM wavelength division multiplexing) comportant à la fois des chemins optiques transparents et des chemins opaques à travers un réseau de commutation électronique, tel qu'un commutateur d'interconnexion numérique à grande vitesse (DCS) et mettant en oeuvre des conversions opto-électroniques du signal de donnée. La commutation tout-optique est mise en oeuvre du côté entrée et du côté sortie, par exemple au moyen de commutateurs à fibres actionnés mécaniquement. Le commutateur DCS, qui reçoit des entrées optiques en provenance des commutateurs optiques d'entrée et qui délivre des sorties optiques aux commutateurs optiques de sortie, met en oeuvre la commutation dans le domaine électrique et peut effectuer la conversion de longueurs d'onde des signaux le traversant. Ce commutateur DCS rend également possible l'accès à des lignes électriques d'insertion-extraction assurant l'interface avec un client. Le chemin optique transparent, qui peut être soit direct, soit passer par un commutateur optique, achemine un signal, quelque soit son format, de l'entrée vers la sortie du système de commutation. Un algorithme permet de définir les connexions requises à travers les différents composants.

Title: Holding element for an implant and ampoule for storing the implant
Inventor: SCHMUTZ WERNER
IPC: A61C8/00
Filed: 1998-05-25
Abstract: The proposal is for a holding element (100) which can be screwed into the internally threaded bore (14) of the implant (1) even during production of the latter and can thus be used to grip or hold the implant for the following production phases. Furthermore, the holding element (100) serves to fix an implant (1), which is screwed thereto, inside an ampoule (200) and for the application of a screwing-in tool for implantation. The particular feature of the ampoule (200) lies in the fact that it has a large-area, lateral cutout (231) in the casing and also a fixing part (210) for accommodating the holding element (100) in a clamped manner. The implant (1) can thus be pulled laterally out of the ampoule (200).    The devices facilitate handling of the implant (1) during production and insertion into the bone.   (Fig. 5)

Filed: 1998-06-18
Abstract: A set of generalized architectures, frameworks, algorithms, and devices for separating, discriminating, and recovering original signal sources by processing a set of received mixtures and functions of said signals based on processing of the received, measured, recorded or otherwise stored signals or functions thereof. There are multiple criteria that can be used alone or in conjunction with other criteria for achieving the separation and recovery of the original signal content from the signal mixtures. The system of the invention enables the adaptive blind separation and recovery of several unknown signals mixed together in changing interference environments with very minimal assumption on the original signals. The system of this invention has practical applications to non-multiplexed media sharing, adaptive interferer rejection, acoustic sensors, acoustic diagnostics, medical diagnostics and instrumentation, speech, voice, language recognition and processing, wired and wireless modulated communication signal receivers, and cellular communications.

Filed: 1998-07-10
Abstract: A composition which elicits antibodies to greater than 95 %, and even greater than 99 %, of the known variants of HIV-1 Tat protein contains at least one peptide or polypeptide of the formula of Epitope I (based on amino acids 2-10 of HIV-1 Tat consensus sequence) and optionally one or more of a peptide or polypeptide of Epitope II (based on amino acids 41 to 51 of that sequence), of Epitope III (based on amino acids 52-62 of that sequence), or of Epitope IV  (based on amino acids 62 through 72 of that sequence with a C-terminal Pro).  Vaccinal and pharmaceutical compositions can contain one or more such peptides associated with carrier proteins, in multiple antigenic peptides or as part of recombinant proteins. Various combinations of the Epitope I through IV  peptides can provide other compositions useful in eliciting anti-Tat antibodies which cross-react with multiple strains and variants of HIV-1 Tat protein. Vaccinal and pharmaceutical compositions can contain the antibodies induced by the peptide compositions for use in passive therapy. Diagnostic compositions and uses are described for assessing the immune status of vaccinated patients.
Patent CA-2297136-A1 (CA)
Inventor: HARDY MEL
IPC: E21B7/06
Filed: 2000-01-21
Abstract: A one-trip apparatus and method involves a bypass valve operated in conjunction with an MWD tool in a bottomhole assembly. The milling system for the window, the whipstock, and the anchor are run in together with the bypass valve and MWD tool. The whipstock is oriented using the MWD tool with circulation through the bypass valve. The bypass valve Is actuated to close and locks closed to allow subsequent setting of the packer or bridge plug once the whipstock has been properly oriented. The mills are supported to the whipstock between a pair of lugs and rotationally locked to one of the lugs. Pressure at a predetermined level releases the rotational lock and mere rotation of the mills allows for formation of the window as the lower lug is milled away. The mills are held to the whipstock with pins through the blocks which are capable of handling greater shear loads than shear pins which have in the past been used to secure the mills to the whipstock.
