Patent CA-2199118-A1 (CA)
Title: A Perforating Blade and Signature
Inventor: FOSTER THOMAS
IPC: B42D1/00
Filed: 1995-09-07
Abstract: A perforating blade (10), and signature (32) produced therewith, having a unitary blade (12) that is very narrow in width in proportion to its length, with a cutting edge (16) along one longitudinal side. The cutting edge (16) comprises a combination of a number of spaced-apart straight (22) and angled (20) sections arranged so that the angled sections (20) angle inwardly toward a center point (18) on the perforating blade and along a single side of the cutting edge only. Since the angled sections (20) are all angled to the same side of the blade, the resulting fold line (26) has cuts only on one side (29) thereof. The angled cuts result in ties (28) that twist easily, and that, therefore, result in fold lines (26) that fold cleanly without gusseting or binding.
Patent CA-2199181-A1 (CA)
Inventor: SORSAUR MOHAMED
IPC: E01C11/26
Filed: 1997-03-06
Abstract: The normal methods for removing the snow and glaciate snow from both sidewalks and driveways in the Canadian Cities achieved by blowing them by using trucks, loaders and plows. The snow and ice plowed horizontally, then accumulated longitudinally or collateral under and over the edge of the sidewalk. This glacial accumulation of snow takes special shape like as snowdrift, which its volume and height will increase by increasing the rate of falling snow, and they spread salts and sand, on the grounds. This method achieved periodically and it loses its effectiveness by increasing or more falling snow. In this invention, the glaciate snow, ice and snowdrift will be resisted vertically, in the same time of falling snow. Firstly, by using certain designed heat-system that will be installing and working on the ground's surface by certain method and the heat will help in melting of the falling snow

Title: Method for estimating the hydraulic conductivity of a borehole sidewall fracture
Inventor: TANG XIAOMING
IPC: E21B49/00
Filed: 1997-03-18
Abstract: A method for modeling fracture zones in the sidewall of a borehole and for estimating the hydraulic conductivity thereof. The method first separates Stoneley wavefields into a directly-transmitted wavefield and a one-way (i. e.  downgoing) reflected wavefield from which the depth configuration may be determined. The separated wavefields are corrected for the effects of borehole irregularity due to such effects as washouts and the like by numerically modeling Stoneley wave propagation using caliper and slowness measurements. The hydraulic conductivity is estimated from parameters derived from synthetic and measured Stoneley-wave data across the fracture zone in combination with measurements of the borehole radius.

Title: Pilot signal searching technique for a cellular communications system
Inventor: HAMDY WALID
IPC: H04B1/707
Filed: 1995-11-22
Abstract: An improved method and system for performing a pilot signal searching operation in anticipation of handoff in mobile station (18) communication between base stations (12, 14). The mobile station (18) maintains a list of Active Set pilot signals transmitted from base stations with which the mobile station is to communicate through, and a list of Neighbor Set pilot signals (N) from base stations within a predetermined proximity of the mobile station (18). The searching operation contemplates comparing pilot signal strength measurements corresponding to each base station entry within the Neighbor Set (N) to a first predetermined level. One or more entries from the Neighbor Set (N) having a base station signal strength measurement greater than the first predetermined level may be placed in the Pre-Candidate Set (PC). Tine strength of the pilot signals associated with entries in the Pre-Candidate Set (PC) are then further evaluated to determine eligibility within the Candidate Set (C), from which are selected the entries comprising the Active Set.

Title: Padmounted transformer enclosure and latch
Inventor: WOLFGANG RICHARD A
IPC: H01F27/02
Filed: 1997-10-02
Abstract: An improved enclosure and latching structure for the cable compartment of a tank for a padmounted distribution transformer. The enclosure is of non-conductive fire resistant material. A curved latch arm of non-conductive material is pivotally connected to support structure mounted on the front tank panel of the transformer above the midpoint thereof. The enclosure is shaped to conceal the cable compartment of the tank and is open at the back for engaging the periphery of the tank panel. The enclosure has an opening in the front adjacent the top thereof through which extends locking means secured to the enclosure for mating with locking structure carried at the free end of the latch arm. The locking means in the opening in the front of the enclosure engages the locking structure at an elevation on the enclosure higher than the pivoted end of the latch arm whereby when the locking means and locking structure are tightened, a compression and moment loading is generated which combine to create a force on the enclosure to hold the open back of the enclosure tightly against the periphery of the tank panel.
