Title: Method and system for uniformly accessing multiple directory services
Inventor: CHAN CHUCK Y
IPC: G06F17/30
Filed: 1997-06-27
Abstract: The present invention provides a directory service system for accessing a plurality of directory services in a uniform manner. Each directory service manages information relating to objects of that directory service. The type of information that a directory service manages for an object is defined by the object class of the object. An object class defines the properties (i.e., information) that a directory service manages for objects of that object class. Each property has a property name and property type. A directory service has a property value for each property defined by the object class of each object. The directory service system comprises a schema browsing component, a name resolving component, a binding component, and an extending component. The schema browsing component controls the retrieving of the property name and property type of each property of each object class of each directory service. A client of the directory service system uses the schema browsing component to retrieve property names and property types of the object classes. The name resolving component controls the receiving of a unique identifier of an object within a directory service and the locating of the object within the directory service. The binding component controls the binding to an in-memory object representing a located object within a directory service. The extending component controls the defining of new object classes and new properties for each directory service. A client of the directory service system uses the extending component to define new object classes and new properties.

IPC: B07C5/34
Filed: 1995-12-22
Abstract: Un appareil (20) de séparation de détritus emploie un transporteur vibrant (24) servant à constituer une mince couche d'articles distincts dans un flux de déchets urbains (22). Ces articles sont alors amenés séparément à des bandes transporteuses espacées (26) qui les font passer sous une rangée de lampes à infrarouge (28). Immédiatement après être passés sous l'éclairage de ces lampes, ces objets sont représentés en images par un système vidéo à infrarouge (30). Une caméra vidéo à infrarouge produit une image vidéo dans laquelle des couleurs spécifiques renvoient à une plage spécifique de températures. Les données de sortie de la caméra vidéo sont traitées pour séparer des images d'une seule température, traitées à leur tour afin de commander la mise en marche de pinces à dépression individuelles faisant partie d'une rangée de pinces à dépression (38) situées au-dessus de la bande transporteuse transportant lesdits articles de déchets urbains. Les ordres de mise en marche, qui dérivent d'une image thermique particulière représentant une plage particulière de températures, sont transmis à une rangée contiguë de pinces à dépression disposées les unes à la suite des autres. De la sorte, il est possible de séparer des articles faisant partie d'un ensemble de déchets urbains en fonction de leurs propriétés thermiques.

Abstract: An endless accumulating conveyor has upper and lower guide rails for supporting pallets. An endless roller chain has an upper run extending along the upper guide rails and a lower run extending along the lower guide rails. A dogging device on each pallet is engageable between the rollers of the chain to move the pallet with the chain along the upper and lower runs. A friction clutch for the dogging device of each pallet causes the dogging device to release and slip past the rollers of the chain when the pallet encounters a predetermined resistance to movement as when it is desired to accumulate pallets. Mechanism is provided for positively propelling each pallet over the curved section at both ends of the conveyor from one run to the other without slipping.

Patent CA-2218509-A1 (CA)
Title: Apparatus and methods for sharing idle workstations
Inventor: WANG YI-MIN
IPC: G06F15/16
Filed: 1997-10-16
Abstract: The present invention relates to systems for sharing idle workstation computers that are connected together through a network and shared file system. More particularly, a user of a local host workstation may submit jobs for execution on remote workstations. The systems of the present invention select a remote host that is idle in accordance with a decentralized scheduling scheme and then continuously monitor the activity of the remote host on which the job is executing. If the system detects certain activity on the remote host by one of the remote host's primary users, the execution of the job is immediately suspended to prevent inconvenience to the primary users. The system also suspends job execution if the remote host's load average gets too high. Either way, the suspended job is migrated by selecting another idle remote workstation to resume execution of thesuspended job (from the point in time at which the last checkpoint occurred).

Title: Safety valve for water supply system
Inventor: STARANCHUK GEORGE P
IPC: D06F39/08
Filed: 1997-11-21
Abstract: A safety control valve for a domestic water supply system is described.  It includes a valve body having a flow passage therethrough comprising a pair of laterally spaced vertical flow channels and a top flow cavity connecting these vertical flow channels.  The top ends of the spaced flow channels open into a flat bottom face of the top flow cavity, which flat face forms a valve seat.  A closure flap is mounted in the top cavity and is spring biased downwardly against the flat bottom face to close the valve.  A central cylindrical cavity extends vertically between the bottom of the top flow cavity and the bottom of the valve body with a thin elastic diaphragm closing the top end of the cylindrical cavity.  A solenoid is mounted on the bottom of the valve body concentric with the central cylindrical cavity. An actuating pin is mounted within the cylindrical cavity and solenoid, this actuating pin being spring biased upwardly such that when the solenoid is not activated the pin moves upwardly extending the diaphragm and pushing the closure flap upwardly to open the valve and when the solenoid is activated the pin is pulled downwardly thereby allowing the closure flap to move downwardly and close the valve.  Connector means are provided for connecting the vertical flow channels to a water pipe and locking means are provided for locking the actuating pin in closed position.  Finally, there is included a probe means for detecting a water leak and thereby activating the solenoid.

Title: Procedure for distinguishing between an internal arc and a breakdown arc in an electrical installation under a metallic sheathing
Inventor: PENNING JEAN-FRANCOIS
IPC: H02H1/04
Filed: 1997-12-15
Abstract: Method for discriminating between an internal arc and a circuit opening arc detected in a device contained in a metallic envelope having at least a set of busbars(1) and a interrupter switch(2) and fitted with a protection system(4) and a computer(5). The method detects the appearance of the arc(c) by means of a sensor(8) which generates an arc apparition signal(c) and transmits this signal to the computer(5) and determines the time lapse T = t0 - ta between the reception instant t0 of a trigger command(o) for the switch(2) transmitted to the computer(5) and the start instant ta of the acquisition of this signal by the computer(5). If the time lapse T is positive, the arc is deduced to be an internal arc. If the time lapse T is negative and the absolute value is less than or equal to 10ms, the arc is deduced to be an internal arc. If the signal presents a rupture point in the 500ms following its acquisition start, the arc is deduced to be an internal arc. If the signal does not present a rupture point in the 500ms following its acquisition start, the arc is deduced to be an rupturing arc.
