Abstract: On décrit un système de distribution d'énergie par induction sans contact, fonctionnant à 10kHz équipé d'une alimentation résonnante à accord automatique reliée à un chemin conducteur primaire résonnant (10110, 10111) comprenant une paire de conducteurs à fils de litz parallèles (10110, 10111) chacun desquels est enrobé dans une gaine isolante et porté par une poutre monorail (10101) sur laquelle une pluralité de véhicules électriques peut circuler. Chaque véhicule est muni d'un moteur électrique adapté à être alimenté par une bobine résonnante collectrice (10115) dont le fil est enroulé sur un noyau de ferrite (10102) monté sur le véhicule à proximité immédiate des conducteurs primaires (10110, 10111). Chaque véhicule est muni de moyens de commutation (10116) susceptibles d'empêcher qu'un véhicule faiblement chargé ne constitue une charge réduite au primaire résonnant. A cet effet, on prévoit une bobine d'isolation (10116) munie d'un interrupteur qui commute la bobine entre un circuit ouvert et un court circuit, de sorte que lorsque le commutateur passe d'un état à un autre, le couplage d'énergie entre le chemin conducteur primaire (10110, 10111) et la bobine collectrice (10115) est modifié.

Abstract: A transceiver device for use with a microcontroller and a symbol encoder decoder device (forming a node in a communications network) for transmitting and receiving variable pulse width modulated (VPWM) analog signals containing symbol messages over a communications bus. The transceiver accepts digital VPWM signals from the symbol encoder decoder device which were generated by the microcontroller and converts the digital signals into VPWM analog signals and then transmits the analog signal over the bus to other nodes. The transceiver also receives VPWM analog signals placed on the bus by other nodes of the network and transfers the signals in digital form to the symbol encoder decoder device which, in turn, communicates the decoded messages to the microcontroller.

Title: Lock-out mechanism for empty/load changeover valve
Inventor: PASEK STANLEY JOHN
IPC: B60T8/18
Filed: 1994-03-22
Granted: 1998-12-15
Abstract: A lock-out assembly having a latching mechanism by which means a plunger may be manually depressed and latched in a lock-out position in which a lock pin is pre-set by engagement with an actuator rod of an empty/load valve or the like, so that in response to axial extension of the actuator rod sufficient to align a locking groove in the actuator  rod  with  the  lock  pin,  locking engagement therebetween will occur to limit further axial extension of the actuator rod, without any further action on the part of the operator.  Automatic disengagement of the lock pin from the locking groove of the actuator rod occurs in response to axial retraction of the actuator rod,  by effecting disengagement of the latching mechanism to allow a return spring to reset the plunger.

Granted: 2004-09-07
Abstract: The indicating device (3) is used for signalling a faulty condition of an electrical apparatus, in particular of a surge arrester (1). It contains a sensor (resistor 10) which is located in an insulating material housing (6) and is intended for detecting a fault current flowing through the apparatus, as well as a two-piece metal housing (4) surrounding the insulating material housing (6). The sensor (10) and the insulating material housing (6) are part of a switching element (5). This switching element (5) causes the insulating material housing (6) to spring apart, by the formation of compressed gas, when the fault current occurs and displaces the two parts (shells 12, 13) of the metal housing (4), making the indicating element (16) visible and forming a DC connection which carries the fault current.

Granted: 2001-06-05
Abstract: The catalyst comprises a mixture of hydrocracked residual asphaltene and metal-doped coke. The catalyst is produced by mixing an oil-soluble metal compound catalyst precursor (e.g. Mo or Ni soap) with heavy oil containing asphaltene and hydrocracking the mixture, producing solid coke as a byproduct. The residual asphaltene fraction in the hydrocracked oil is then precipitated, for example with n-pentane. The mixture of solid coke and precipitated asphaltene is separated and used as the catalyst for hydrocracking a new batch of non-hydrocracked oil. The coke and asphaltene mixture provides as effective a catalyst as the original metal soap catalyst precursor. The coke and asphaltene mixture recovered from a second stage of coke and asphaltene mixture catalysed hydrocracking of heavy oil is still an effective catalyst and can be used again without significant loss in catalytic activity. Similarly, coke and asphaltene mixture from non-catalytic hydrocracking of bitumen displays a catalytic effect which, however, is lower than that described above.

Title: Anti alpha-galactosyl screening technique
Inventor: POULETTY PHILIPPE
IPC: C12Q1/02
Filed: 1996-09-27
Granted: 2002-08-27
Abstract: Compounds and libraries are labeled with a galactosyl epitope and then screened in accordance with an assay involving cells having a characteristic of interest. Conveniently, the screening may embody target cells, where the compounds are brought in contact with the cells. Each of the compounds carries with it the information of its identity or method of synthesis. After washing away non-specifically bound compounds, blood may be applied to the cells, whereby antibody binding to the galactosyl epitope initiates the complement cascade. Plaques are identified and the compound associated with the plaque identified. The formation of the plaque demonstrates that the compound has specific affinity for the target cell, binding of the compound to the cell does not interfere with binding of the antibody, and that the complex is capable of cytotoxic activity by means of the complement cascade.
Patent CA-2209135-C (CA)

Abstract: There is currently no specific immunological treatment utilizing live virus for infection by Human Immunodeficiency Virus (HIV) which is a cause of a clinical syndrome called Acquired Immunodeficiency Syndrome (AIDS). Several prior attempts have been made to develop vaccines to boost the humoral immune response to envelope and gag proteins which have been uniformly unsuccessful because of various factors including cell-to-cell propagation of the HIV and its destruction of the cell mediated immune system of the body by its cytopathic and fatal effect on THELPER (CD4) cells. The present invention describes a method of creating a recombinant HIV virus clone with its nef gene deleted. The invention further describes a method of creating an injectable suspension of the virus particles and preferred treatment protocol for patients infected with the HIV. A protocol for the prevention of wild-type HIV infection has also been described. It is believed that the preferred embodiment works by eliminating blocking of induction of IL-2 mRNA and IFN.gamma. in lymphoid cells by the nef protein, by developing a cell mediated immune response to HIV via cytotoxic T Lymphocytes (CTL) and by competing with the wild-type HIV for potential hosts and thus increasing the likelihood of exposure of the wild-type HIVto humoral antibodies to gp120, gp41 and gag proteins.

Abstract: The present invention is an optical monitoring and test access interconnection module especially adapted for use with a fiber optic distribution frame for a fiber optic communications system. The interconnection module provides a combination of monitoring and test access for two fiber lines, typically a transmit/receive pair, where wavelength division multiplexer (WDM) test access is provided to both the transmit and receive fibers. In one embodiment of the present invention, the interconnection module monitors only the receive fiber line where a power monitoring circuit receives a monitor level optical signal via an optical tap and converts the optical signal to an electrical output: Processing electronics and firmware within the module are operable to generate alarms and other control signals when changes in the power level of the received signal are detected. A test access path is provided on the module for use, for example, with an optical time domain reflectometer (OTDR). In one embodiment of the present invention, the interconnection module incorporates a unique physical design arrangement that separates the optical signal processing from the electronic processing into partitioned sub-modules. The optical and electronic sub-modules may advantageously be assembled (and dis-assembled) by means of guides that allow the module halves to slide together. A unique optical mating connector is provided in the sliding arrangement to join the optical module to an opto-electronic photodetector in the electronic module.
