Filed: 1998-10-29
Abstract: A watthour meter socket adapter has front and rear housings which encompassingly surround jaw contacts, electrical conductors and terminals. Apertures in the housing allow insertion of a meter blade terminal into the jaw contacts. The jaw contacts include a spring clip having a recess sized for slidably receiving one side of a conductor to dispose the conductor for direct contact with a meter blade terminal. At least two conductors overlay each other and are separated by an insulating pad. The terminals include a collar having a recess for partially receiving one side of a circular conductor or in the case of a rectangular bus bar conductor, a bore is offset to one side edge of the terminal collar for receiving a lower portion of the bus bar. The upper portion of the end of the conductor is folded over to form a flange overlaying a bottom portion of a first bore in the terminal collar and engages an external conductor. A surge ground frame includes a unitary terminal portion overlaying a terminal portion of the housing. A  communication connector is mounted in the sidewall of the housing for external communications to the adapter. A lockable cover is provided for the communications connector.

Title: Apparatus and method for distributing management keys in a multicast domain
Inventor: LI YUNZHOU
IPC: H04L12/18
Filed: 2000-06-02
Abstract: A method and apparatus for distributing keys in a multicast domain is provided. In a secure multicast domain, a request to join a multicast group for a time period occurs. A key distributor which controls access to the multicast data group determines if the request will be accepted. If the request is accepted the key distributor assigns the member to a virtual channel, wherein each virtual channel is defined by a time period. A data group key is forwarded to the member as is a virtual channel key. The member can then receive and decode events from the data group on the assigned virtual channel.

Title: Method and apparatus for detecting leakage current on a two wire dc or ac power line
Inventor: HALVORSON DAVID H
IPC: H02H3/17
Filed: 2000-07-14
Abstract: A method and apparatus detects leakage current on a two wire power line and, in particular, provides a way to prevent hazardous electrical shocks to personnel on ECP equipped railroad trains. Two resistors of equal value are respectively connected in series to the two wires of the power line. A sensing resistor is connected in series with a junction of first two resistors, and a low voltage power source is connected between the sensing resistor and earth ground. A sensor is connected across the sensing resistor to detect a leakage current. The sensor is capable of detecting either positive or negative leakage currents. An output of the sensor is supplied to a controller which controls a high voltage power source connected across the two wires of the power line to be either in an OFF state or enabled to be in an ON state, depending on whether a leakage current is sensed by the sensor.

Patent CA-2319196-A1 (CA)
Inventor: DELARUELLE DALE
IPC: B60T17/22
Filed: 1999-01-27
Abstract: A railway brake system (10) for a train includes a brake pipe extending along the train, a lead unit controller (29) generating a pneumatic control signal propagated along tho brake pipe, and at least one remote unit controller (25, 28). The remote unit controller preferably includes a brake pipe control valve, such as a relay valve (26), connected in fluid communication with the brake pipe (20) for selectively charging and exhausting the brake pipe, an air flow rate sensor (30, 31) for sensing air flow into the brake pipe during charging, a brake pipe pressure sensor (40) for sensing brake pipe pressure, and a processor (36) for detecting the pneumatic control signal from the lead unit controller based upon both the air flow rate sensor and the brake pipe pressure sensor. Accordingly, the sensitivity of detection is increased despite delayed operation of the relay valve, and while avoiding false indications. Multiple detection sensitivities may be used.  The detection may be used to cut-out the remote unit controller and idle down the locomotive, as when radio communications are lost. The detection may also be used for brake pipe continuity testing and/or to determine the relative position of the remote unit along the train.

Filed: 1999-04-22
Abstract: La présente invention concerne la visualisation ultrasonique, en particulier d'une perfusion dans le myocarde et autres tissus, au moyen de nouvelles préparations d'agent de contraste renfermant du gaz. Une fois injectées, ces préparations favorisent une croissance maîtrisée et temporaire de la phase gazeuse in vivo et peuvent donc jouer le rôle de marqueurs de perfusion déposés. Les préparations renferment un milieu aqueux injectable composé de gaz à l'état de dispersion et d'une émulsion huile dans eau injectable dans laquelle la phase huileuse comprend un agent pouvant se diffuser in vivo dans le gaz dispersé et favoriser la croissance momentanée dudit gaz, de sorte que la matière présente sur les surfaces de la phase gazeuse dispersée et la matière présente sur les surfaces de la phase huileuse dispersée aient une affinité mutuelle, notamment à cause de leurs charge opposée. En ce qui concerne la visualisation de perfusions cardiaques, les préparations peuvent être utilement co-administrées avec des vasodilatateurs de type adénosine, le but étant d'accentuer les différences d'intensité entre signaux de retour selon que le tissu myocardique est normal ou en état d'hypoperfusion.

Title: Method of applying chemical anchoring adhesive
Inventor: ERNST RICHARD J
IPC: C09J163/00
Filed: 2001-07-20
Abstract: A method of applying a chemical anchoring adhesive to the interior of a borehole includes the steps of providing a highly viscous, self-contained slug of chemical anchoring adhesive, inserting the slug into the borehole, providing an anchor pin, and driving the anchor pin into the borehole using a driving tool that imparts rotary motion to the anchor pin. The adhesive slug includes a first part having a first color and including a resin, and a second part having a second color different from the first and including a curing agent. The rotary motion of the anchor pin mixes the first and second parts together to form a substantially homogeneous composition having a third color different from the first and second colors. The visual indication provided by the third color notifies the worker when the mixing is complete, saving time and money at the construction site while minimizing the occurrence of defective or insufficient mixing.

Filed: 1999-12-08
Abstract: L'invention concerne un procédé permettant de générer une définition de flux de commande de programme à partir du code de programme, qui détermine des points d'entrée dans ledit programme. Le code est suivi, ou balayé, à partir d'un point d'entrée vers une instruction de branchement ou de saut, ou vers une instruction de commande de flux. Un bloc de code est ensuite défini, comme étant le code, à partir du point d'entrée vers l'instruction de commande de flux, et comprenant ladite instruction. Cette opération est répétée pour chaque point d'entrée possédant une valeur connue, résultant d'une définition partielle de flux de commande. Pour les points d'entrée présentant une valeur inconnue, une analyse de propagation constante est exécutée sur la définition partielle du flux de commande, afin de convertir des valeurs inconnues de point d'entrée en valeurs connues. Enfin, les points d'entrée déterminés par l'analyse de propagation constante sont utilisés comme points de départ de l'étape de balayage, afin de définir des points d'entrée supplémentaires. Les étapes de balayage, effectuées à partir des points d'entrée de bloc afin de déterminer des points supplémentaires, et utilisant une propagation constante pour déterminer des points d'entrée de bloc supplémentaires pour des valeurs inconnues, sont répétées de façon à étendre la définition de commande de flux. La propagation constante est utilisée uniquement lorsqu'ils n'existe pas de points d'entrée de bloc connus. La connaissance heuristique peut être utilisée pour déterminer certaines valeurs inconnues. En outre, une connaissance du système d'exploitation sur lequel le programme tourne peut être utilisée pour déterminer certaines valeurs inconnues. Un mode de réalisation préféré est mis en oeuvre avec une liste de travail de bloc qui comprend une liste de tous les blocs connus du programme, et qui définit le flux de commande partiel du programme informatique pendant une analyse, et le flux de commande complet lors de l'exécution de cette analyse. Une liste de travail d'entrées de bloc comprend une liste de tous les points d'entrée connus dont les blocs sont inconnus, de sorte que chaque point d'entrée de bloc de la liste de travail d'entrée de bloc est analysé.
