The present invention produces a cold gas stream having a constant temperature and pressure. The gas stream is obtained from two initial streams, one being a liquefied gas and the other being a gas at ambient temperature. The liquefied gas stream is combined with the warm gas stream, causing the liquid to vaporize. The two streams are combined in proportions that yield a cold gas mixture having a desired temperature. The resulting cold gas mixture is directed into an insulated container having a volume significantly larger than the volume of the conduits through which the streams flow. The container therefore acts as a buffer to reduce pressure fluctuations in the stream. A temperature …

Why it's free to use
- Filed October 6, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 6, 2012.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
