Patent CA-2415363-A1 (CA)
Title: Repetitive-pn1023-sequence echo-cancellation reference signal for single-carrier digital television broadcast systems
Inventor: LIMBERG ALLEN LE ROY
IPC: H04N5/44
Filed: 2001-07-11
Abstract: DTV signals transmitted over the air with a symbol rate of around 10.76 million samples per second include echo-cancellation reference (ECR) signals each of which includes or essentially consists of a repetitive-PN1023 sequence with baud-rate symbols, which repetitive-PN1023 sequence incorporates a number of consecutive data-segment synchronization signals. Receivers for these DTV  signals respond to these ECR signals to generate initial weighting coefficients for adaptive filters used for channel equalization and echo suppression. The initial weighting coefficients are calculated from a cepstrum extracted from the repetitive-PN1023 sequence ECR signal by DFT methods or with a PN1023 auto-correlation match filter.

Title: Mass spectrometer
Inventor: BATEMAN ROBERT HAROLD
IPC: H01J49/40
Filed: 2003-08-08
Abstract: A mass spectrometer is disclosed wherein a relatively energetic pulse of ions having a relatively narrow spread of mass to charge ratios are ejected from a quadrupole ion trap T2 and received in an ion trap TO upstream of a Time of Flight mass analyser. The ions are collisionally cooled within the ion trap TO and are pulsed out of the ion trap TO and into an extraction region 3 of the Time of Flight mass analyser without substantially exciting the ions. This enables improved operation with the Time of Flight mass analyser.      According to another embodiment parent ions are fragmented and the resulting fragment ions are stored in two ion traps having different low mass cut-offs. The trapping system enables MS/MS experiments to be performed with a very high duty cycle.

Abstract: An inspection system for detecting flaws in oil and gas well borehole ferromagnetic tubulars. The inspection device operates inside the tubular by first saturating tubular wall with magnetic flux. Flaws in the wall causes flux leakage, and the magnitude of the flux leakage are measured with Hall effect sensors disposed within the inspection device. The magnitude of flux leakage is then related to the amount of ferromagnetic material loss resulting from the flaw. Eddy currents induced in the wall are also measured and combined with the Hall effect sensor measurements to define location and geometric shape of the flaw.

Abstract: A method of conveniently and efficiently producing reduced coenzyme Q10having excellent qualities which is useful in foods, foods with nutrient function claims, foods for specific health uses, nutritional supplements, tonics, animal drugs, drinks, feeds, cosmetics, drugs, remedies, preventives and so on. This method is suitable for industrial production thereof. An oily oxidized coenzyme Q10product is reacted with a reducing agent in water and the aqueous phase is separated from the thus obtained reaction mixture.  Alternatively, an organic phase containing reduced coenzyme Q10 is concentrated by distilling off the coexisting organic solvent at the melting point of the educed coenzyme Q10 or higher. Thus, an oily coenzyme Q10 product with excellent qualities having a low viscosity and favorable handling properties can be produced. Further, a desired solvent is added to the oily product thus obtained to give a solution or a slurry of the reduced coenzyme Q10. Alternatively, it is brought into contact with seed crystals to thereby give a solid reduced coenzyme Q10 product.
