Patent CA-2209218-A1 (CA)
Inventor: BARRERA GIORGIO
IPC: H02K15/04
Filed: 1997-06-27
Abstract: Apparatus and methods are presented for forming and inserting multi-lobed coils into slots of a stator for an alternator, the coils constituting the winding of the stator.  The apparatus includes first and second coiling stations and a coil inserting station.  The first and second coiling stations form and load, either sequentially or independently, a coil-inserting tool with first and second multi-lobed semi-coils angularly offset from each other by approximately one half-wave such that the lobes of one semi-coil are located in the spaces between the lobes of the other semi-coil.  The coil-inserting tool is then transferred to the coil inserting station where the first and second semi-coils are substantially simultaneously inserted into at least some slots of a stator, each engaged slot receiving a portion of both first and second semi-coils.
Patent CA-2209571-A1 (CA)
Title: Package for containing and applying a bug repellent patch
Inventor: COOK CHARLES DENVER
IPC: A01N25/18
Filed: 1996-01-02
Abstract: A pouch package, containing a volatile solution-impregnated patch, is made of a peelable barrier film. The pouch envelops an absorbent substrate saturated preferably with bug repellent fluid. A PSA (pressure sensitive adhesive) coated backing film is laminated to the absorbent substrate. The backing film has a connecting portion which is peelably sealed to the inside of the pouch.  When the pouch is peeled open, the PSA coated backing film is exposed and placed against a target surface, such as a patch wearer's clothing. Finally, the side of the pouch facing the absorbent substrate is peeled off the backing film connecting portion to expose the absorbent substrate. A key to functionality of the pouch package is differential adhesion. First, the pouch barrier film must be peelable from itself, yet it must not adhere to the pressure sensitive adhesive on the backing film. A release paper may be used to cover the PSA when peeling the pouch open. Second, the pouch film must be peelable from the backing film connecting portion without disturbing the bond between the fastening surface and the target surface. Third, the backing film must be laminated to the absorbent substrate more strongly than the PSA  adheres to the backing film, so that when the patch is removed from the target surface, the PSA stays with the patch.

Patent CA-2215224-A1 (CA)
Title: Interpreting formation tops
Inventor: BOUZAS HORACIO R
IPC: G01V1/48
Filed: 1997-09-12
Abstract: Formation tops correlation is interpreted between sampled log curves by a weighted combination of covariance, the ratio of standard deviation, and the ratio of summed amplitude. This covariance function is computed and evaluated appropriately for the geologic environment over a sliding analysis window. Correlations are determined for any number of wells and any number of events in each well. Geologic rules are used to establish a parameter for the algorithm operation and for the analysis of the resulting function. The geologic rules include bounding guide horizons, sequence rules, and a covariance cutoff parameter. Bounding horizons are picked from pre-existing seismic or geologic interpretations and from map grids. The rule set includes onlap, truncated, conformable, and unstructured sequence definitions. Additional geologic complexity such as crossover, repeat sections, and inverted sections are accommodated by the rule set. Back-correlation for cross-over sections and loop-tying for map interpretation are performed for validation.

Title: Electrothermal chemical cartridge
Inventor: WILKINSON GREGORY MARK
IPC: F42B/
Filed: 1995-03-23
Abstract: An electrothermal chemical cartridge (10) with a fuse (18) of tapering cross section enables higher impulse energy to be imparted to a projectile (6) by means of complete controlled burning of propellant (24). A  long, narrow tube (16) filled with propellant (24) has a fuse (18) on its inside surface with a cross section that tapers toward the discharge end, separated from the electrical ground of the cartridge casing by a layer of insulation sufficiently thin to be destroyed as the fuse ignites the propellant. A high-voltage electrode (26) connected at the back end (14) of the tube (16) provides for application of a pulse of sufficient current density to ohmically heat or burn the fuse in a controlled fashion from the discharge end (12) to the back end (14). Many such tubes (152) can be bundled together in a large casing (150) for wide barrel guns.

Title: High resolution intravascular signal detection
Inventor: LAU LIMING
IPC: A61B5/296
Filed: 1996-05-08
Abstract: A system for detecting electrical activity within a patient's heart comprising an elongated intravascular device (10), such as a catheter or guidewire, having a plurality of sensing electrodes (16) on a distal section of the elongated device to detect electrical activity from within a blood vessel of the patient's heart. The intravascular device has a first compact array (17) with a relatively small interelectrode spacing, such as less than 2 mm, and may have a second electrode array (20) with an interelectrode spacing much greater than the interelectrode spacing in the first array. The second electrode array may be used to detect the general region of the arrhythmogenic tissue and the first electrode array is used to provide a high resolution of the electrical detection to more accurately pinpoint the location of the arrhythmogenic site. When the general region of the arrhythmogenic focus is known, an intravascular device having a single array of electrodes with an interelectrode spacing of less than 2 mm may be used.
Patent CA-2222165-A1 (CA)
Title: System and method for resolving substantially simultaneous bi-directional requests of spare capacity
Inventor: WILL RUSS
IPC: H04L69/40
Filed: 1996-06-07
Abstract: In a self healing network (SHN) distributed restoration algorithm (DRA) scheme, in the case where two adjacent tandem nodes (5, 6) are contending for the same spare link (S47), an arbitration scheme is used to determine which node has the right to reserve the spare link (S47) for its use. An arbitration timer (34, 40) in each of the adjacent nodes (5, 6) provide a predefined time period for which a node can compare whether it had begun sending out its flooding signature before the far end node had sent out its. Thus, when a node detects a signature received from the spare link before the predetermined time period has elapsed, then the node give up the spare link (S47) for the far end use. If the signature, from the far end node is detected after the predetermined time has elapsed, then the node reserves the spare link (S47) for its own use.

Title: Capsule holder for rotary mixing device
Inventor: LISSNER WERNER
IPC: B01F29/90
Filed: 1998-04-06
Abstract: A capsule holder for retaining a mixing capsule on a rotary mixing device includes a carrier plate 10, an actuator disk 11 rotatable relative to the plate, and two retaining arms 12, 13 for clamping the capsule from opposite sides, the retaining arms having driving pins 22 engaging spiral cam slots 26 of the actuator disk 11.

Inventor: MELBERG JOHN M
IPC: C06C7/00
Filed: 1996-10-04
Abstract: A lead-free rim-fire primer mix which utilizes cupric azide, a highly sensitive chemical, as the primary explosive in lieu of lead styphnate. The cupric azide is mixed with carefully selected proportions of nitrocellulose, tetracene, fine particles of ground glass and a binder, typically gum tragacanth. When mixed in the proper proportions, this mix has the required sensitivity, stability, and non-hygroscopicity for regular commercial rim-fire ammunition. The tetracene is not required as a sensitizer, but is used as an ignition aid. The preferred range of percentages are 10-36 % by weight of cupric azide, 5-10 % by weight of tetracene, 15-30 % by weight of nitrocellulose, 20-50 % by weight of glass, and 1-2 % by weight of a suitable gum.

IPC: H04L12/56
Filed: 1998-04-16
Abstract: An  internetwork  relay  system  and  method  for transmitting IP traffic including an edge and a core. The edge includes an ingress and egress routers and the core  includes  a  switch  network.   The  ingress  router communicates  with  and  receives  an  IP  packet  from  a source network.  The ingress router attaches to each IP packet, a globally unique label which is used to forward the  IP packet  across  the network.   The  relay  switch network communicates with the ingress router,  receives the IP packet from the ingress router and forwards the IP  packet  along  its  transmission  path  based  on destination information included in its attached label. The egress router receives the IP packet from the switch network and forwards it to a destination network.   Once received, the destination network forwards the IP packet to its intended destination.
