Patent CA-2288060-A1 (CA)
Inventor: NEVILL STUART MICHAEL
IPC: H04R1/28
Filed: 1998-04-29
Abstract: The loudspeaker system comprises: a loudspeaker drive unit (2) and a tube (4) acoustically coupled to the rear of the loudspeaker drive unit for leading away and absorbing sound waves produced at the rear of the loudspeaker drive unit. The tube is acoustically coupled to the loudspeaker drive unit by means of a hollow resonant enclosure (6) and the loudspeaker drive unit is mounted at an aperture (8) in an external wall of the enclosure. The tube communicates with the interior of the enclosure and extends outwardly from the enclosure. There is a significant change in acoustic impedance where the tube communicates with the interior of the enclosure. The fundamental resonant frequencies of the enclosure and the tube each lie between the first and second frequencies but the Helmholtz resonant frequency of the tube, when its distal end is open, lies below the first frequency. The effect of the enclosure is to "short circuit" sound at the frequencies of the higher order resonances of the tube so that those resonances are not excited to any significant extent.

Patent CA-2298789-A1 (CA)
Inventor: HAM HOWARD M JR
IPC: H01T15/00
Filed: 1997-08-14
Abstract: Electric arc monitoring is effected by exploiting the discovery that electric arcs are fractal phenomena with all essential information that signifies "arc" contained in each fractal subset. These fractal subsets are logarithmically distributed over the arc spectrum. Monitoring of arcs is most advantageously effected on a fractal subset of low logarithmic order where the amplitude is higher pursuant to the 1/f characteristic of electric arcs (22), where cross-induction among neighboring circuits is lower, and where travel between the arc and the arc signature pickup (23) is longer than at the high frequencies customary for arc detection. Fractal subset transformation reduces the danger of false alarms. Arc signature portions may be processed in out of phase paths or treated as modulated carriers.

Title: Chimeric binding peptide library screening method
Inventor: MCGREGOR DUNCAN
IPC: C12N15/10
Filed: 1998-09-02
Abstract: There is described a method of isolating nucleotide sequences encoding target peptides from DNA libraries using DNA binding proteins to link the peptide to the sequence which encodes it. DNA libraries are prepared from cells encoding the protein of interest, or from synthetic DNA, and inserted into, or adjacent to, a DNA binding protein in an expression vector to create a chimeric fusion protein.  Incorporation of the vector DNA into a carrier package, during expression of the chimeric fusion protein, results in the production of a peptide display carrier package (PDCP) displaying the DNA-bound fusion protein on the external surface of the carrier package. Employment of affinity purification techniques results in the PDCP particles containing sequences encoding the desired peptide to be selected and the desired nucleotide sequences obtained therefrom.
