Abstract: A method of measuring the quenchability of a liquid coolant used to cool objects such as ingots produced by direct-chill casting. The method involves providing a sample of the liquid coolant; providing a probe for immersion in the sample, the probe having a temperature-sensing electrical device contained therein which generates an electrical response corresponding to temperature sensed; heating the probe in a gas, preferably by means of electrical resistance heating by a circuit which is electrically connected to the temperature-sensing electrical device, to a predetermined temperature measured by the electrical response of the temperature sensing device, immersing the probe into the sample and measuring the electrical response for a predetermined measurement period, and comparing the measured electrical response to a response of a reference liquid measured under equivalent conditions, to thereby determine the quenchability property of the liquid coolant. The invention also relates to apparatus for carrying out the method, as well as a method and apparatus for controlling the cooling of the object based on the measured quenchability of the coolant. In an alternative, the probe may be heated by means other than the electrical resistance heating at a rate of at least about 40 °  C/second.

Patent CA-2299330-A1 (CA)
Inventor: DRUBE THOMAS K
IPC: F25B19/00
Filed: 1998-08-05
Abstract: A cryogenic liquid transfer system releases stored cryogen from a bulk storage tank (12) to a gas supply tank (16, 26) and a dispenser tank (18. 28). The liquid cryogen (10) in the gas supply tank (16, 26) is circulated through a heat exchange (54) and the gas generated is returned to the gas supply tank (16, 26) to pressurize it. The pressurized liquid cryogen is released from the gas supply tank (16. 26) so that it flows through a vaporizer (64). The gas produced by the vaporizer is bubbled through the liquid cryogen in the dispenser tank (18, 28) so as to raise its temperature and pressure to the level required by the use device being serviced. Gas from the vaporizer is then delivered to the space above the liquid cryogen in the dispenser tank (18, 28) to create a pressure head to cause the liquid cryogen to flow to the use device. A venturi (40) is used to reduce the pressure in the bulk storage tank.

De cette manière l'arbitre de bus est programmable en raison de sa capacité à configurer l'arbitre de bus pour organiser et conduire le transfert de données entre les divers dispositifs et parmi ces derniers. Les divers bus peuvent comprendre un circuit d'interface pour leur permettre d'être reliés correctement au bus programmable. Chaque dispositif comprend un tampon d'entrée et un tampon de sortie, le tampon d'entrée comportant des premier et deuxième tampons et le tampon de sortie comportant lui aussi des premier et deuxième tampons. Le bus programmable est également constitué d'une ligne de sélection de tampon transportant un signal de sélection de tampon, de manière à ce que le signal de sélection de tampon informe les divers dispositifs s'ils doivent utiliser le premier ou le deuxième tampon des tampons d'entrée et de sortie pour transférer les données. Dans une forme de réalisation, le double tamponnage facilite le transfert des données sur la base d'horloges de fréquences d'échantillonnage différentes.

Patent CA-2311081-A1 (CA)
Title: Rfi canceller using narrowband and wideband noise estimators
Inventor: FENTON DAVID KENNETH
IPC: H04L25/02
Filed: 2000-06-09
Abstract: In order to overcome problems when using an adaptive filter for cancellation of common-mode noise in digital subscriber loops, caused by a portion of the differential signal being converted to common mode, which degrades the performance of the filter, a noise cancellation technique is proposed which compensates for this cross-coupled signal energy. In particular, a narrowband noise estimator is used to detect one or more noisy frequency bands of the common mode signal and derive therefrom a first noise estimation signal. A wideband noise estimation unit derives from the remainder of the common mode signal a second noise estimation signal. Both the first and second noise estimation signals are subtracted from the differential signal. The wideband noise estimation unit comprises a bandstop filter for removing the frequencies detected by the narrowband noise estimator, an analog-to-digital converter for converting the bandstopped signal to digital form, and an adaptive filter for deriving the second noise estimation signal from the digitized bandstopped signal and in the process compensating for phase and gain differences, especially attributable to the interference being injected at different points along the length of the channel.
