Patent CA-2207525-A1 (CA)
Title: Continuous dry granulation of powdered carbon black
Inventor: KOPIETZ JAN
IPC: C01B32/384
Filed: 1997-06-10
Abstract: The invention relates to a process and apparatus for the continuous dry granulation of powdered carbon black.          Granulation is performed with the assistance of a toothed-shaft granulator which has, in a circular, cylindrical, drum-shaped stator with a longitudinal axis, an axially-arranged toothed shaft which rotates about the longitudinal axis of the stator and conveys the powdered carbon black from the inlet to the exit of the granulator, with simultaneous granulation.  The teeth have a diameter and a length, and are arranged on the shaft axially-offset with respect to each other along a helical line around the shaft.  The maximum peripheral speed of the ends of the teeth is between 1 and 6 m/s, and the average residence time for the carbon black in the granulator is between 20 and 600 seconds.  Perferrably, the axial distance between neighbouring teeth is less than their diameter so that complete covering is provided by the teeth along the axis, and the length of the teeth is selected so that the clear space between the ends of the teeth and the stator wall is 0.5 to 3 mm.  It is advantageous to have the teeth arranged on the shaft along two or more helical lines.  This means that, for comparably-sized equipment, the carbon black throughput can be increased several times as compared with pelletising drums used in a conventional manner.

Title: Self-tapping screw-type masonry anchor
Inventor: GIANNUZZI LOUIS N
IPC: F16B25/00
Filed: 1997-07-29
Abstract: A self-tapping, screw-type anchor capable of being turned into a hole drilled in masonry whose hardness renders the wall of the hole highly resistant to a tapping action.  The anchor includes a thread forming a helical ridge on the root of the anchor, the thread having a profile defining a pair of opposing curvilinear flanks rising above the root and converging toward a crest.  The curvature of the flanks which is preferably hyperbolic, creates a crest having a small included angle adapted to penetrate the wall of the hole, the crest being supported on a relatively broad base that merges with the root to firmly secure the thread thereto and thereby prevent deformation or mutilation of the thread as the anchor is being turned into the hole.

Title: Method to determine local variations of the earth's magnetic field and location of the source thereof
Inventor: TOWLE JAMES N
IPC: G01V3/26
Filed: 1997-08-13
Abstract: A method to determine the earth's magnetic field vector along a sub-surface wellpath having unknown and possibly changing azimuth, in the presence of a magnetic disturbance caused by a magnetic source external to the wellpath includes estimating the three components of the earth field along the three axes of a magnetic sensor package by a polynomial function of measured depth along the wellpath. Magnetic survey accuracy is thereby improved. Upon removal of the earth's magnetic field from the measurements, the resultant magnetic field of the disturbance is determined and can be used to determine the position and orientation of the source of the disturbance.

Patent CA-2215563-A1 (CA)
Title: Combined laser and plasma arc welding torch
Inventor: PARNETA IGOR
IPC: H05H1/26
Filed: 1997-09-15
Abstract: A welding torch which combines features of both laser and plasma-arc welding torches. A laser beam is directed by an objective lens so that it is co-linear with the central axis of a plasma-arc torch. The laser beam passes through a planar or conical cathode electrode placed at the bottom orifice of the torch. A coaxial aperture having a diameter less than that of the laser beam is drilled into the cathode to allow the laser beam to pass through the cathode. A constricting nozzle is placed under the cathode, with the laser beam passing through the axis of the nozzle. As with a standard plasma-arc torch, a gas is forced through a chamber having the cathode and nozzle at its bottom end. As the cathode is heated by the laser radiation, the gas is ionized and a plasma-arc is formed. As the laser beam passes through the nozzle, it comes to a focus and interacts with the plasma-arc formed between the cathode and a workpiece. The resulting interactions between the plasma-arc and laser beam form a plasma-laser discharge which acts to additionally constrict the laser beam and plasma-arc and increase the energy density of the welding spot formed on the workpiece.

Patent CA-2226376-A1 (CA)
Inventor: VENKATESAN SUBBARAYAN
IPC: H04Q3/00
Filed: 1998-02-11
Abstract: This invention includes a path-based method and system that restore a distributed telecommunications network (90) from a failure condition (92). First, the method and system notify all the network nodes (22, 29, 26, 28) of the fault of a link (12). Next, an alternate route finding phase occurs for finding alternate paths (S-T1-T4-D) to reroute the disrupted traffic. For finding alternate paths (S-T1-T9-D), the alternate route finding phase includes sending messages (70, 100) throughout the distributed telecommunications network. Upon finding some alternate paths (S-T1-T4-D), the method and system send connect commands (100) to make the necessary cross connections in the distributed telecommunications network nodes (22, 24, 26, 28) that are on the alternate paths (S-T1.-T4-D).      Throughout the distributed network restoration process, the method and system synchronize (62) the distributed telecommunications network nodes to avoid possible race conditions among the nodes.
Patent CA-2228260-A1 (CA)
Title: Weak signal resolver
Inventor: DODLEY JEEVAN PRAKASH
IPC: H04B1/10
Filed: 1998-01-30
Abstract: A receiver is provided in which a composite signal is split into two paths. In the first path, a desired signal channel is suppressed by a notch filter. The remaining channels in the composite signal are inverted. In the second path, the signal is delayed to match the delay imposed by the first path. The signal from the first path is recombined with the second path, which reduces the signal level of the undesired channels to the level of quantization noise. The desired signal can then be amplified using the full dynamic range of the amplifier circuitry. If desired, more than one channel may be received at a time. Further, if the two or more channels that are being received have different signal strengths, the digital filtering functions of the notch filter can be used to selectively weight the signals to equalize their strengths. In addition, channels of different bandwidths can be received.
