Patent CA-2319059-A1 (CA)
Inventor: SMALL LEONARD EDWIN
IPC: A23L27/30
Filed: 1999-01-29
Abstract: La présente invention concerne un agent édulcorant destiné à divers aliments/boissons instantanés. La composition de cet agent est la suivante: 1) entre environ 90 % et environ 99,5 % de sucrose, fructose, lactose, glucose et tout mélange desdits sucres; 2) entre environ 0,001 % et environ 5 % d'aspartame; et 3) entre environ 0,001 % et environ 5 % d'acésulfame K. L'agent édulcorant selon la présente invention convient aussi bien pour des préparations médicamenteuses que pour des denrées alimentaires et des boissons. Il est idéal pour les compositions alimentaires qui renferment classiquement des matières solides en proportion élevée (plus de 12 % généralement). L'agent édulcorant peut s'utiliser dans des boissons en poudre ou prêtes à l'emploi (cafés et thés aromatisés ou non, chocolat chaud, boissons à base de jus), boissons nutritives sous forme de boissons frappées, de malts et analogues (par exemple Ensure?); puddings; sauces, jus de viande; sauces à salade; mousses; crèmes glacées; yogourts; fromages à la crème; sauces au fromage (dips) pour amuse-gueule et fromage à tartiner; crème aigre; sauces pour fondues de légumes ou pâtés végétaux; glaçages; nappages fouettés; préparation surgelées; lait, colorant à café; sauces de type "dip" et produits à tartiner. Le mélange de sucre (sucrose, fructose, lactose, glucose et tout mélange desdits sucres) et d'édulcorants (aspartame et acésulfame K) permet de réduire le pourcentage de denrées solides (quantité de poudre) nécessaire pour confectionner de multiples denrées alimentaires et boissons (telles que boissons sans alcool, entremets à la gélatine, desserts surgelés et analogues). Ce mélange accentue davantage la saveur sucrée que ne le ferait la simple adjonction de ces trois produits. L'agent édulcorant selon la présente invention a également pour effet de rehausser la saveur et la richesse de goût des boissons ou des mets préparés; alors que les autres édulcorants font office d'exhausteurs de goût. De plus, l'agent édulcorant selon l'invention ne laisse pas l'arrière goût caractéristique associé aux autres édulcorants et dont l'amertume est généralement attribuée à l'aspartame.

The aperture wall, filter support and filter member are removably mounted within the dirt cup to provide for removal and cleaning thereof.
Patent CA-2335006-A1 (CA)
Title: Method and apparatus for performing packet loss or frame erasure concealment
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

Title: Improvements in ms/ms scan methods for a quadrupole/time of flight tandem mass spectrometer
Inventor: THOMSON BRUCE
IPC: H01J49/42
Filed: 2001-06-01
Abstract: There is provided a method of effecting mass analysis on an ion stream, the method comprising passing the ion stream through a first mass resolving spectrometer, to select parent ions having a first desired mass-to-charge ratio. The parent ions are then subject to collision-induced dissociation (CID) to generate product ions, and the product ions and any remaining parent ions are trapped; the CID and trapping can be carried out together in a linear ion trap. Periodically pulses of the trapped ions are released into a time of flight (TOF) instrument to determine the mass-to-charge ratio of the ions. The delay between the release of the pulses and the initiation of the push-pull pulses of the TOF instrument are adjusted to maximize the duty cycle efficiency and hence the sensitivity for a selected ions with a desired mass-to-charge ratio. This technique can be used to optimize the performance for a parent ion scan, and MRM scan or a neutral loss scan.
