Patent CA-2174769-A1 (CA)
Title: Well tool
Inventor: JONES LLOYD GARNER
IPC: E21B43/04
Filed: 1994-11-22
Abstract: A well tool (20) for delivering fluid (e.g. sand or gravel slurry) to different levels within a wellbore which is comprised of delivery conduit (21) which, in turn, has a plurality of exit ports (29) spaced along its length.  Each exit port has an exit tube (27) connected thereto.  Each exit tube (27) includes a portion whose length lies substantially parallel to the longitudinal axis of the delivery conduit (21) which permits larger exit ports to be used which, in turn, substantially reduces the likelihood of an exit port (29) becoming blocked to completion of a well  operation. Also, where at least a portion of an exit tube is inside the delivery conduit (21), the concentration of the sand flowing through the exit tube (27) will be substantially the same as the original concentration in the slurry since sand particles will not tend to by-pass an exit port (29) and remain in the slurry.  This prevents the premature dehydration of the slurry and the resulting buildup of sand within the delivery conduit (21) which is normally associated therewith.
Patent CA-2175781-A1 (CA)
Inventor: ACHARYA DIVYANSHU R
IPC: C07C253/24
Filed: 1996-05-03
Abstract: A petrochemical (i.e. a hydrocarbon derivative) is produced by the vapour phase reaction of a hydrocarbon with air in the presence of a suitable catalyst. The petrochemical is removed from the reactor effluent, and part or all of the remaining petrochemical-free gas stream is passed through a hydrocarbon-selective adsorbent, which adsorbs hydrocarbon from the gas stream, leaving a hydrocarbon-depleted waste gas. Hydrocarbon is purged from the adsorbent with air, and the air-hydrocarbon mixture is recycled to the partial oxidation reactor. The purge air, and preferably both the purge air and the petrochemical-free gas stream are dried by passage through beds of zeolite 3A prior to being introduced into the hydrocarbon-selective adsorbent, and the beds of zeolite 3A are regenerated by passing heated hydrocarbon-depleted waste gas therethrough. <IMAGE>

IPC: G10L15/22
Filed: 1994-06-17
Abstract: In methods and apparatus for at least partially automating a telephone directory assistance     function, directory assistance callers are prompted to speak locality or called entity names associated with desired directory listings. A  speech recognition algorithm is applied to speech signals received in response to prompting to determine spoken locality or called entity names. Desired telephone numbers are released to callers, and released telephone numbers are used to confirm or correct at least some of the recognized locality or called entity names. Speech signal  representations labelled with the confirmed or corrected names are used as labelled speech tokens to refine prior training of the speech recognition algorithm. The training refinement automatically adjusts for deficiencies in prior training of the speech recognition algorithm and to long term changes in the speech patterns of directory assistance callers served by a particular directory assistance installation. The methods can be generalized to other speech recognition applications.

Title: Apparatus for applying an apex filler to a bead ring
Inventor: BULL JEFFREY F
IPC: B29D30/50
Filed: 1997-01-17
Abstract: The assembly applies an apex filler to the outer circumferential surface of an annular bead ring. The apex filler applying assembly incorporates an apex filler applicator that is preferably operable in conjunction with a plurality of server mechanisms. One server mechanism is a conveyor that receives a bead ring. A locator operates in conjunction with the conveyor to position the annular bead ring precisely on the conveyor so that it may be engaged by a transfer mechanism. The transfer mechanism removes the bead ring from the conveyor and mounts it on a chuck turret assembly. A chuck head in the chuck turret assembly engages the bead ring and accurately positions the bead ring relative to applying rollers in the apex filler applicator, in which position the apex filler -which has been directed from an extruder through an orienting mechanism, into an in-feed mechanism and severed to length by an in-flight guillotine cutter -is applied to the annular bead ring. After the apex filler has been applied to the bead ring the transfer mechanism removes the finished tire bead sub-assembly from the chuck head and deposits the tire bead sub-assembly on the conveyor for removal from the assembly.

IPC: H04B15/00
Filed: 1997-01-31
Abstract: An undesirable energy suppression system in a contention based communications network having a shared communication path between a plurality of remote points and a headend in a simplex network or a bidirectional network. The system includes a method and apparatus for transmitting a signal on the shared communication path from any one of the plurality of remote points contending for the shared communication path, to the headend. The signal includes a gate enabling signal also known as a prybar signal. The shared communication path includes a gate where the gate connects the shared communication path when the gate is closed, and the gate disconnects the shared communication path when the gate is open. The system controls the gate in response to receiving the gate enabling signal. Absent a gate enabling signal, any signal or other energy on the shared communication path will not propagate through the network because the shared communication path is disconnected. In one embodiment a single gate is located where it can serve an entire distribution branch of remote points in a tree and branch style network. In another embodiment there is a gate dedicated to each individual remote point in the network.

Filed: 1995-08-16
Abstract: In a method of communication using quantum cryptography, single-photon signals from a highly attenuated source are modulated and subsequently detected. In the step of detecting the modulated signal, the signal is split between two branches according to its encoded state. Signals corresponding to different encoded states are detected independently in the respective branches and the rate of detection of coincident signals is determined. This rate is compared with a threshold to detect the presence of an eavesdropper.
