Abstract: PCT No. PCT/EP95/05113 Sec. 371 Date Jun. 18, 1997 Sec. 102(e) Date Jun. 18, 1997 PCT Filed Dec. 22, 1995 PCT Pub. No. WO96/20135 PCT Pub. Date Jul. 4, 1996In order to treat water contaminated with warfare agents and containing less than 500 ppm of salt, a separation stage 10 is normally provided downstream of the reverse osmosis. In the separation stage, the untreated water is divided into residue and permeate. Warfare agents have the property of acting as softeners on the semi-permeable organic polymer membranes of separation stages. As a result of this, the warfare agents pass through the membranes of separation stages in increasing quantities once the latter have been in operation for a few hours. In order to improve the treatment of water contaminated with warfare agents, salt is added to the untreated water which, with a salt content of over 1000 ppm, is then drawn through the separation stage 10 down stream of the reverse osmosis stage. The invention is suitable for use with mobile facilities used for producing drinking water.

Filed: 1998-06-15
Abstract: The present invention pertains to a system and method for tracking object references in an object-oriented computing system including a number of independent computing nodes interconnected by a communications link. The reference counting mechanism tracks references to an object at three levels. At a first level, the server handler associated with an object is used to track local references to the object by other user applications within the same domain. At a second level, the inter-process communications facility (i.e., door facility) is used to track object references that are exported to different domains within the same node. At a third level, the kernel object request broker (ORB) is used to track object references that are exported outside the node. When all external object references are released, the ORB notifies the object's server handler of this occurrence. Similarly, the door facility notifies the object's server handler when all inter-domain references have been released. The object'sserver handler will initiate the appropriate reclamation procedures when it receives notification from the ORB and the door facility and when its own local references have been relinquished.
