Patent CA-2270365-A1 (CA)
Inventor: NEWSOM MORRIS F
IPC: C08L27/06
Filed: 1997-05-15
Abstract: A microencapsulatable solvent adhesive composition for coupling plastic conduits, such as pipes, connectors and related fittings comprises a water-insoluble polymer and a mixture of volatile organic solvents for the polymer, each of the solvents having 6 to 40 carbon atoms. This solvent adhesive composition is suitable for microencapsulation by aqueous-based microencapsulation processes. A plurality of microcapsules encapsulating the solvent adhesive composition are bound to a polymeric surface of a conduit, such as a pipe connector or fitting, by a binder composition, to form a surface coated with a layer of rupturable microcapsules. When the microcapsules are ruptured upon joining of the coated conduit to a second conduit, the volume of the released solvent adhesive composition is sufficient to cement the surfaces together.

Title: Receiver decoder circuitry, and associated method, for decoding a channel encoded signal
Inventor: KHAYRALLAH ALI S
IPC: H03M13/01
Filed: 1997-12-12
Abstract: Decoder circuitry, and an associated method, decodes an encoded signal received at a receiver. A determination is made of the levels of distortion introduced upon a signal during its transmission to a receiver upon a nonideal communication channel. If the communication channel introduces moderate amounts of distortion upon the signal, a complex decoding technique such as a standard trellis decoding technique is utilized to decode the signal. If the channel is determined to introduce only small levels of distortion upon the signal, a relatively simple, decoding technique is instead utilized.

Title: Method of detecting corrosion in pipelines and the like by comparative pulse propagation analysis
Inventor: BURNETT GALE D
IPC: G01N17/00
Filed: 1998-06-04
Abstract: A method of dectecting corrosion on an elongate member (10), such as a pipe (10). Far side and near side electric pulses are transmitted into a magnetically permeable pipe (10) at spaced locations to travel toward one another. These are synchronized to intersect at various locations on the pipe (10). The resulting waveforms are analyzed by combining adjacent waveforms resulting from pulses intersection at spaced locations. Two combined waveforms are analyzed by subtracting one from the other to produce a difference waveform and the difference waveforms are compared to detect corrosion.
