Patent CA-2312092-A1 (CA)
Title: Gas phase fluidized bed method and ethylene homo- and copolymers obtained using said method
Inventor: HECKER MANFRED
IPC: C08F2/34
Filed: 1998-11-26
Abstract: The invention relates to a continuous gas phase fluidization method for producing ethylene homopolymerisates and copolymerisates with a density (d) of 0.87 to 0.97 g/cm3. According to said method, ethylene or mixtures of ethylene and C3- to C8-.alpha.-monoolefins are (co)polymerised in the polymerisation zone of a gas phase fluidized bed reactor at pressures of 1 to 100 bar and at temperatures of 30 to 125 ~C in the gas phase in an intermixed bed of fine particulate polymerisate in the presence of a supported chromium catalyst. The polymerisation heat produced is evacuated by cooling the reactor gas, said reactor gas being guided in a closed circuit, and the resulting (co)polymerisate is transferred out of the gas phase fluidized bed reactor. In order to produce a (co)polymerisate of a pre-selected density (d), the (co)polymerisation is carried out at a temperature within a range limited by an upper envelope of equation (I) and a lower envelope of equation (II), the variables in said equations having the following meanings: TH = the highest reaction temperature in ~C; TN = the lowest reaction temperature in ~C; and d'= the numerical value of the density (d) of the (co)polymerisate to be produced.

Patent CA-2320767-A1 (CA)
Inventor: PILLSBURY NATHAN H
IPC: G05B19/29
Filed: 1999-12-16
Abstract: L'invention concerne un contrôleur de déplacement et un procédé de contrôle du déplacement d'une pluralité d'axes. Ledit contrôleur empêche de générer une commande de position discontinue à un axe suiveur. Un circuit ou une routine de fonction de transfert en mode suiveur créé une commande de position en réponse à une position d'axe maître. Cette fonction peut se présenter sous la forme d'un mécanisme de transmission ou de came électronique. Un verrou de sollicitation permet de compenser tout changement de position découlant d'un changement de mode, par exemple le passage du mécanisme de transmission électronique à celui de came électronique, changement des profils de came ou des rapports de transmission, ou changement de l'axe maître. Le verrou est ajouté à la commande de position de la fonction de transfert et une commande de position du générateur de profil de commande de mouvement standard pour alimenter la commande de position de l'axe suiveur. Le verrou est recalculé à chaque modification du mode suiveur. On peut utiliser une commande d'arrêt pour bloquer ou activer sélectivement un signal de commande de mouvement indépendant, l'axe suiveur restant en mouvement lorsque le mode suiveur est arrêté (ne suivant pas l'axe maître), ou mis en marche pendant que l'axe suiveur est en mouvement sans changement brusque de position. Le circuit de calcul de déclenchement permet de calculer préalablement la synchronisation de l'activation du mode suiveur lorsque ce dernier passe de la position arrêt à la position marche, pendant que l'axe suiveur est déjà en mouvement, de sorte que les axes sont en phase après délai d'intégration.

Title: Automatic inspection system with stereovision
Inventor: JACKSON CHRISTOPHER B
IPC: H04N13/239
Filed: 1999-12-17
Abstract: In one embodiment of the present invention, two banks (22, 24) of fixed array cameras provide tiled stereo images (I1, I2, I3) and electronics assemble the tiled stereo images into a mosaic image. The mosaic image includes height information derived from the two sets stereo images, and is also compensated as a function of reference points in the image to more closely conform to the actual board (10). Preferably, a SAM model is used to locate the reference points. Reconstructed SAM models corresponding to components on the board are applied within a search area where a certain type of component is expected to be found. The best-fit location of the component within the search area, as well as the skew angle and the probability are computed. The best-fit location is the location where the Manhabolis distance and the residual error are optimized. Once the best-fit location is computed, it is compared to tolerances to identify improperly placed components, the absence of components or the like.

Patent CA-2328758-A1 (CA)
Title: Optical circulators
Inventor: ZHANG YONG
IPC: G02F1/09
Filed: 2000-12-19
Abstract: An optical circulator having a dual fiber collimator and a single fiber collimator is described. The circulator provides a non-reciprocal functionality that directs input signals from a first fiber of the dual fiber collimator to the single fiber collimator. Input signals from the single fiber collimator are directed to a second fiber of the dual fiber collimator. The circulator includes birefringent wedges that change the angle of signals from the single fiber collimator to direct the signals to the second fiber of the dual fiber collimator. Because the circulator includes two collimators rather than three collimators, the circulator is more compact than a circulator having three collimators.

Filed: 1999-07-16
Abstract: A telecommunication network node which integrates the voice and data services provided to a wireless mobile unit. The network node receives a request for information along with a voice network identification of the mobile unit via the signaling portion of the voice network. The network node performs a database lookup to determine a data network address of the mobile unit. This data network address may be a permanent data network address or a temporary data network address. The network node sends the information request to a data network service provider, whereby the request may be enhanced with information added by the network node. Upon receipt of the requested information from the data network service provider, the network node forwards the information to the mobile unit via the data network using the data network address.

Title: Adaptive location level
Inventor: SCHULTZ JOHAN
IPC: H04W60/02
Filed: 1999-12-17
Abstract: The present invention involves apparatus and method for providing page messages to mobile radios based on the mobility rates of the mobile radio. For mobile radios that are relatively stationary, page messages are sent to a cell in which the mobile radio resides, while radios which are increasingly mobile receive their page messages on a local area basis. The mobile radio only performs location updates when the situation is optimized for doing so depending upon the mobility of the radio, the introduction of a new cell, the introduction of a new location area, the expiration of a pre-determined time limit and the status of a new cell location flag. A function is defined for location updating on either a locationary basis or a cell basis in accordance with each of the above factors in order to optimize the burden of location area updating and unwanted page broadcasting.
