Title: Labeled primer for use in and detection of target nucleic acids
Inventor: WEIMER THOMAS
IPC: C12Q1/68
Filed: 1998-12-14
Abstract: Labeled primer for use in and detection of target nucleic acids A labeled primer (for example for the polymerase chain reaction) is described, which primer is labeled at the two ends of the oligonucleotide strand with a reporter dye molecule and a quencher molecule, and in which labeled primer at least the last base at the 3' end is not complementary to the DNA sequence to be amplified. A process for detecting a DNA sequence (by means of the polymerase chain reaction) using the labeled primer is also described, which process uses, for the amplification, one or more thermostable DNA polymerases, one of which also possesses proof-reading properties and releases the unpaired bases of the labeled primer together with the quencher molecule which is attached thereto, resulting in an increase in the fluorescence at the wavelength of the reporter dye and thereby indicating the formation of the DNA sequence which is labeled with this fluorescent dye.

Title: Automatic fault location in cabling systems
Inventor: SORAGHAN JOHN JAMES
IPC: H04B10/07
Filed: 1997-09-26
Abstract: A method and apparatus (12-20, 32) for automatically locating faults in a network of signal carriers (cables) utilises an interrogation waveform which is pulse-like in form and receives composite reflected signals from the carriers which are a time distributed collection of individual reflections.  These are sampled and compared using the function of an adaptive filter (52) to minimise the difference signal. The difference signals are analysed to determine significant points of departure which identify the fault location which is then represented as a distance value.

Patent CA-2272012-A1 (CA)
Title: Communication plug having low complementary crosstalk delay
Inventor: PHARNEY JULIAN ROBERT
IPC: H01R13/6473
Filed: 1999-05-11
Abstract: A communication plug that generates crosstalk that complements the compensating crosstalk in a legacy jack or connector. The communication plug includes a dielectric carrier on which a plurality of electrical conductors are disposed. Each conductor is configured to wrap around a first end of the carrier thereby forming a series of adjacent inductive loops. Complementary crosstalk is generated between the conductors as a result of the fields created from current flow through the inductive loops and can be fixed to a desired level by modifying certain engineerable parameters. The inductive loops are positioned in the nose or front region of the plug where the conductors engage the jack spring wires or terminals thus minimizing the propagation delay between the crosstalk signals generated in the plug and the crosstalk signals generated in the jack or connector.
Patent CA-2275065-A1 (CA)
Inventor: LLOYD GRAEME JOHN
IPC: H02H3/08
Filed: 1999-06-17
Abstract: When directional overcurrent protection relays (22, 32) are included at the load end of a set of parallel feeders (20, 30) fed from an AC power source (10), a minimum fault-current threshold is specified based on the potential of a phase-to-phase fault at the source to cause a relay to operate misleadingly. This threshold is, for plain (transformerless) feeders, approximately 50% and, for transformer feeders, approximately 85% (nominally 86.7%) of rated pre-fault load current. These thresholds can, however, be ignored if, according to a second aspect of the invention, the relay outputs are processed in a 2-out-of-3 circuit (91), so that a relay on one phase will only operate its associated circuit breaker if a relay on another phase has also operated, a condition which has been found not to obtain in the case of a source fault.
