Patent CA-2242621-A1 (CA)
Inventor: PLEE DOMINIQUE
IPC: B01D53/047
Filed: 1998-07-21
Abstract: On décrit des agglomérés de faujasite X de rapport Si/Al = 1 dont, d'une part le liant inerte a été transformé en zéolite active par zéolitisation dans une liqueur alcaline, et qui ont été d'autre part soumis à un échange lithique poussé. Ces adsorbants développent une capacité d'adsorption d'azote (1 bar/25.degree.C) d'au moins 26 cm3/g, ce qui en fait d'excellents adsorbants pour la séparation non cryogénique des gaz de l'air ainsi que pour la purification de l'hydrogène.

Abstract: A coal gas stream containing H2S and COS is desulphurised by passing it radially into a vessel (300), wherein the coal gas stream is entrained into a high momentum turbulent jet of gaseous zinc (308) passing downwardly through the vessel (300). The resultant desulphurised gas stream and solid zinc sulphide are separated in a hot gas cyclone (320). Any excess gaseous zinc is solidified by passing through a waste heat boiler (322) and is separated from the desulphurised gas stream by hot gas filtration.

Title: Available speed ratio modification for splitter transmission
Inventor: PALMERI FRANK A
IPC: F16H61/70
Filed: 1998-10-02
Abstract: A multi-speed transmission has a main transmission section and a splitter section. The electronic control for this transmission is operable to either provide the actuation of the splitter system or not allow that actuation. Thus, the operator of the vehicle is able to request either a smaller cumber of available speed ratios or a larger number of available speed ratios by selecting the appropriate electronic control. The vehicle manufacturer is able to tailor the vehicles to have a transmission which is appropriate to the needs of its customer without having to change the transmission. Moreover, upon resale, a transmission that was initially provided with only a smaller number of speeds may be easily upgraded to provide additional speeds. In a second embodiment of this invention, the control is reprogrammable to either provide or not provide actuation of the splitter gear. The control may be actuated remotely, such as by a satellite, to provide the additional speed ratios based upon expected driving conditions.

Title: Optimized routing of terminating calls within a mobile telecommunications network
Inventor: PATEL MAHESH
IPC: H04W8/10
Filed: 1997-09-15
Abstract: A call setup signal is routed to the gateway mobile switching center (GMSC) serving a public land mobile network (PLMN) associated with a called mobile station. The GMSC then sends a signal including data identifying the originating switch to the home location register (HLR) associated with the called mobile station. Upon determining that it would be more efficient and direct for the originating switch to release the first call connection to the GMSC and to re-originate a new call setup signal directly towards the mobile switching center (MSC) currently serving the called mobile station, the HLR transmits a Mobile Application Part (MAP) based signal to the originating switch. As a result the originating switch releases the original call connection and re-originates a call setup signal using a roaming number identifying the MSC currently serving the mobile station as a destination address.

Abstract: L'invention concerne un système permettant de jouer à des jeux électroniques, comprenant un serveur (200) de jeu et un ou plusieurs terminaux (300) de joueurs. Les résultats des jeux sont fondés sur un nombre aléatoire (225, 325) généré par le serveur (200) de jeu et par chacun des terminaux (300) de joueurs. Le serveur (200) de jeu et les terminaux (300) de joueurs coopèrent dans le but d'assurer que les nombres aléatoires sont générés de manière indépendante. Ainsi, tant les joueurs, que l'hôte du jeu, par exemple un casino, peuvent Ètre sûrs que les résultats du jeu ne sont pas frauduleux. Dans un certain mode de réalisation, les nombres aléatoires (225, 325) sont transmis entre le serveur (200) de jeu et les terminaux (300) de joueurs, sensiblement au même temps. Dans d'autres modes de réalisation, les nombres aléatoires (225, 325) sont codés et échangés entre le serveur (200) de jeu et les terminaux (300) de joueurs, les clés (294, 375) permettant de décoder les nombres aléatoires étant échangées ultérieurement.

Title: Hdtv video frame synchronizer that provides clean digital video without variable delay
Inventor: NEMIROFF ROBERT
IPC: H04N19/89
Filed: 1999-07-02
Abstract: A system for processing a sequence of video or other data frames at a data encoder (100) during a sync loss. During a sync loss of input data at a video or other data encoder, substitute data such as black video (142) is used to provide complete "clean" data frames to a compressor (150) at the encoder (100). Artifacts due to compression and encoding of partial frames are avoided. If a sync loss is detected in the middle of a particular data frame that is input to the encoder, the remainder of the frame is completed with substitute data (142) which is in sync with the earlier data in the frame. Additional complete frames of the substitute data are provided to the compressor (150) following the particular data frame, still in sync with the particular frame, until such time that a sync recovery is detected, and a field or frame check is performed on the new, post-sync loss, data to gain confidence of the sync recovery. A null signal (143) may be provided to the compressor after the last substitute frame, and prior to the post-sync loss frame after the frame in which the field or frame check occurs. Different frame and video clock rates in the post- versus pre-sync loss frames are automatically accounted for.

Inventor: FALK KEVIN
IPC: G01B5/00
Filed: 1999-07-30
Abstract: A method for capturing data representative of a geometry of a raw cylinder head casting in order to obtain a casting scanning coordinate system for use with a machining coordinate system utilizes a locating device during a non-contact scanning operation. The cylinder head casting includes horizontal planar cast locators and vertical cast locators. Planar data corresponding to the planar cast locators is determined by scanning planar areas of the device.      Vertical data corresponding to the vertical cast locators is determined utilizing locating features disposed on a planar surface of the device and located at predetermined positions with respect to the vertical cast locators. A transformation matrix defining a relationship between the scanning coordinate system and the machining coordinate system can then be determined based on the planar and vertical data so that virtual machining can be performed in predicting the volume of a machined cylinder head.
