    摘要: A method of extending the shelf life of foodstuffs comprises the steps of evacuating gas from the foodstuff and treating the foodstuff with carbon dioxide and sulphur dioxide either in admixture or sequentially. The gases are then evacuated from the foodstuff, which is sealed into a container under an inert gas. In cases where the preserved foodstuff is likely to exude moisture during storage, water may be removed from the product. Foodstuffs treatable by the method include fruit such as apples.

    摘要: A slickline data transmission system for a high pressure oil-field well comprises inductive couplers at opposite ends of a slickline in order to establish real-time radio communication between down-the-hole logging toolstrings and supervisory control and data acquisition equipment on the surface. A frequency shift keyed (FSK) carrier centered around radio is used to send data up to the surface and commands back down to the toolstring. The toolstring itself can be a conventional one with a TDMA interface originally intended to be memory-dumped when the toolstring is returned to the surface.
