Abstract: A method of processing bit vectors or raw bit strings wherein the bit vectors or raw bit strings are input to a binary tree structure of processing elements. Each processing element performs a boolean "OR" operation on a pair of inputs to produce an output stream of compressed bit string fragments. Processing takes place according to dataflow principles, wherein the processing element is activated when data is available at its inputs. The output compressed bit string fragments are buffered in a FIFO before being input to another processing element at a lower level of the binary tree. A resultant bit vector or raw bit string is output from the processing element representing the root node of the binary tree. The resultant bit vector or raw bit string is a representation of the result of the boolean "OR" of all inputs.

Patent CA-2288630-A1 (CA)
Title: Improvement in cathodic protection system
Inventor: BENNETT JACK E
IPC: C23F13/02
Filed: 1999-11-08
Abstract: The present invention relates to the field of cathodic protection of reinforced concrete. A conductive metal is thermally applied onto an exposed surface of the concrete in an amount effective to form an anode on the surface.      This establishes an interface between the anode and the concrete. The thermal application is performed in a manner which is effective to impart permeability to the anode. A solution or dispersion comprising a surface active agent capable of wetting the anode external surface and a humectant is applied to the external surface of the anode.      The solution or dispersion migrates by capillary attraction to the interface of the anode with the concrete depositing the humectant at the interface. The humectant functions as a current enhancing agent. The humectant also absorbs moisture from the atmosphere thereby providing an electrolyte at the interface. These combined effects substantially increase current delivery from the anode. A preferred humectant is a lithium salt.

Title: System for inspecting in-service gas distribution mains
Inventor: PITTARD GERRY
IPC: G01B7/13
Filed: 1998-06-26
Abstract: A system for inspecting in-service gas distribution mains is disclosed. Coiled tubing technology and magnetic flux leakage (MFL) technology are integrated to produce a new inspection system for low pressure, in-service distribution pipelines. The coiled tubing provides the means by which an inspection module employing MFL technology is inserted into, moved through, and removed from an in-service pipeline. A portable inspection system can thereby be moved to a desired location on a trailer. The sensor module comprises a plurality of magnet assemblies each having a Magnet N out, a Magnet S out and a magnet core, the magnet assemblies being conical in shape and being arranged into a circular array. The magnet array diameter is smaller than that of a pipe to be inspected, thus defining a radial air gap. The magnet array being constructed and arranged to provide a magnetic circuit having sufficient strength so as to be operable through the radial air gap. A centering mechanism is constructed and arranged to maintain the sensor module in concentric relation with the pipe to be inspected. This array provides an efficient method of packing the magnets to generate the very powerful magnetic field desired. The conical shape of the magnets in this assembly permits the unit to negotiate tighter bends than would be possible with a cylindrical assembly. The centering mechanism permits product bypass and minimizes removal of surface debris.

Patent CA-2301033-A1 (CA)
Inventor: HASKINS LORI L
IPC: C03B37/025
Filed: 1998-09-10
Abstract: Optical fiber (14) is drawn from a preform (10) that is fed to a furnace at a constant downfeed rate. The optical fiber (14) is drawn by a tractor (20) at a rate of at least 10 meters per second and the tractor (20) is allowed to vary the draw speed of the fiber (14) based on the fiber diameter as measured by a diameter monitor (15) during the draw processing in order to maintain a relatively constant fiber diameter. Maintaining the preform downfeed rate constant even at high draw rates in excess of 20 meters per second does not adversely effect the draw process and is believed to reduce or eliminate oscillations in the draw control loop that can cause variations in the core shape during fiber formation, resulting in reduced PMD and improved MFD uniformity.
