Title: Dosage de la vigueur d'une semence
Inventor: BUCKLEY WAYNE T
IPC: A01C1/00
Filed: 2002-04-18
Abstract: La vigueur de la semence de diverses plantes cultivées, notamment des plantes à petites graines, est déterminée par mesure des gaz volatiles émis par la semence lorsqu'elle est exposée à diverses conditions. Par exemple, l'éthanol produit par la semence de colza canola (Brassica napus et Brassica rapa) dans un contenant fermé stocké durant 24 heures à température de laboratoire après ajout de 20 % d'humidité à la semence est mesuré par chromatographie gazeuse, par d'autres appareillages de surveillance des gaz ou par changement de couleur dans une substance indicatrice. La quantité d'éthanol déterminée par cette méthode d'analyse indique la vigueur de la semence.

Title: Transformers and cores for transformers
Inventor: GRIMES FRANK H
IPC: H01F27/25
Filed: 1989-12-13
Abstract: ABSTRACT OF THE DISCLOSURE A method of making a transformer having a core composed of a web of magnetic amorphous metal of small thickness. The laminations of the core of the transformer are the stacked turns formed by winding the web into a spiral having a window in the center.  The coils are wound as integral structures having openings for telescoping the coils onto the core.  for the telescoping, the core is cut and converted into a U-shaped structure on whose arms the coils are telescoped.  The cut joint is a butt lap-step joint.  To produce such a joint, the laminations are divi-ded into groups and each group is divided into steps which are spaced longitudinally of the web.  After the coils are telescoped onto the core, the cut ends of the arms of the U are abutted to form a closed core.  The cuts in the lam-inations that make up alternate groups in the stack are inclined to the longitudinal center line of the web at a first angle different from 90°.  The cuts in the laminations that make up intervening groups in the stack are inclined oppositely to the cuts in the alternate groups at an angle which is also different from 90°.  Because of the different inclination of successive cuts, the undesired abutting of laminations from different groups during the reclosing of the core is precluded.  There is also disclosed a core and a transformer made by the method.

Abstract: FAST PURGE BALLOON DILATATION CATHETER                ABSTRACT OF THE DISCLOSURE     A balloon dilatation catheter having a guidewire lumen that extends to the distal tip of the catheter, a balloon mounted on the distal end of the catheter and an inflation lumen extending through the shaft and communicating with the interior of the balloon is provided with an improved arrangement for filling the inflation lumen and balloon with liquid while purging air from the system.  The device includes a one-way valve means carried by the catheter shaft within the balloon which permits fluid flow from the guidewire lumen into the balloon under a predetermined pressure greater than about one atmosphere.  The system is used by first plugging the distal end of the guidewire lumen and then pressurizing the guidewire lumen with inflation liquid sufficiently to open the one-way valve means to permit inflation liquid to fill the balloon.  As the balloon fills, air is forced out of the balloon through the inflation lumen and is vented through the open proximal end of the inflation lumen.  The one-way valve means is constructed to preclude reverse flow under pressures greater than 20 atm and to preclude opening in response to aspiration through the inflation lumen at a level not greater than 1 atmosphere pressure.

Abstract: An AFC circuit for use in a chrominance signal processing circuit of a VTR basically includes a NCO (9), a frequency divider (9, 10, 11, 12, 13) for frequency-dividing an output of the NCO, and a phase comparing circuit (17) for comparing phases, of the output of the divider and a horizontal synchronizing signal extracted from an inputted video signal to supply an error output to the VCO. When a phase relation between the output of the divider and the horizontal synchronizing signal becomes a miss-locked state out of the phase-locked state, a frequency-dividing operation is stopped at a timing corresponding to a rise of a normal inputted signal in a phase-locked state and the frequency-dividing operation is restarted after the inputted horizontal synchronizing signal is counted by a predetermined number.      As a result, the phase-locked state of the inputted horizontal synchronizing signal and the output signal of the divider is forcibly restored.

Abstract: METHOD AND APPARATUS FOR   BAUD TIMING RECOVERY                 Abstract A data communications receiver for use in a modem. A fixed sample clock and a dominant tap tracking algorithm lock the local baud timing in the receiver to the baud timing in a remote transmitter. An interpolating filter provides a plurality of discrete delays. A filter control circuit inspects the tap coefficients of an adaptive equalizer to determine the location of and any movement of the dominant tap. The filter control circuit selects the rate of cycling through the discrete delays to compensate for any frequency difference between the local baud timing and the remote baud timing, and to prevent movement of the dominant tap. A baud detector circuit monitors the sample clock and the operating state of the filter control circuit to identify the end of a baud and detects and corrects for any frequency difference between the remote baud timing and the local baud timing by providing one additional sample or one less sample to the adaptive equalizer. A bit clock circuit monitors the operation of the baud detector and adjusts the bit clock frequency to compensate for the additional or discarded sample.
