Abstract: A method of removing water from an organic liquid in which the water is substantially immiscible is provided. The mixture of water and an organic liquid is directed through a coalescing element which includes a packing material having a critical wetting surface tension intermediate the surface tensions of the water and the organic liquid, to form a mixture of water droplets and the organic liquid.

Abstract: It is now recognized that oxidative stress, an imbalance of antioxidant system against free radicals and reactive oxygen species in ow body, is the basic pathophysiology of many diseases including life-threatening heart disease, stroke, certain cancers, Alzheimer's and age related dementia. Boosting the antioxidant system at specific vulnerable biochemical pathway sites will therefore help to prevent, delay or treat these diseases - an observation confirmed in many studies around the world. There is no existing patent covering 3 different classes of antioxidant ingredients namely Vitamin, (Vit. C, E.), essential minerals (Selenium) and phytonutrients (proanthocyanidins) and co-factors (Vit. B 12, folic Acid) formulated at optimal doses with minimal side effects. In addition, the composition of Ultra-Vit. Plus is based on the synergistic actions in the newly discovered endogenous antioxidant biochemical system in the body.    Ultra-Vit. Plus formula will contribute immensely in the technical field of integrated preventive medicine and basic understanding of mechanism of action in the biotechnology of antioxidant systems.      The Ultra-Vit. Plus formula applying for patent consist of Vit C 500 mg (as calcium ascorbate) Vit E 400 I.U. (as mixed Vit. E Tocopherals, and Tocotrienols) Folic Acid 0.5mg Vit. B 12 500mcg Selenium 90mcs. Proanthocyanidins 90mg (mcg) (Equal mixture of maritime Pine Bark Extract and Grape Seed Extract.) In addition, it is applying for patent use for prevention and treatment of oxidative stress and related diseases.

Title: Adaptive interaction using an adaptive agent-oriented software architecture
Inventor: HODJAT BABAK
IPC: G06F40/00
Filed: 1999-06-14
Abstract: Method and agent network architecture for processing a subject message, wher e each agent has a view of its own domain of responsibility. An initiator agen t which receives a user-input request and does not itself have a relevant interpretation policy, queries its downchain agents whether the queried agen t considers such message to be in its domain of responsibility. Each queried agent recursively determines whether it has an interpretation policy of its own that applies to the request, and if not, further queries its own further  downchain neighboring agents. The further agents eventually respond to such further queries (2024), thereby allowing the first-queried agents to respond  to the initiator agent. The recursive invocation of this procedure ultimatel y determines one or more paths through the network from the initiator agent to  one or more leaf agents. The request is then transmitted down the path(s), with each agent along the way taking any local action thereon and passing th e message on to the next agent in the path. In the event of a contradiction, t he network is often able to resolve many of such contradictions according to predetermined algorithms. If it cannot resolve a contradiction automatically , it learns new interpretation policies necessary to interpret the subject message properly. Such learning preferably includes interaction with the use r (but only to the extent necessary), and preferably localizes the learning close to the correct leaf agent in the network.
Patent CA-2335238-A1 (CA)
Inventor: SOBERON PETER A
IPC: H01M50/202
Filed: 1999-06-04
Abstract: A cover for a battery compartment in a medical device such as an ambulatory pump that is used for infusing a medicinal fluid. The battery compartment cover includes a lever (18) that is pivotal between an open and a closed position. The lever is connected to a plunger (22) that applies a compressive force against an O-ring, which is trapped between a shoulder on a washer through which the plunger extends and an end of the plunger. When the lever is pivoted to its open position, the compressive force on the O-ring is released, enabling the battery compartment cover to be removed from the opening into the battery compartment. However, when the lever is pivoted to its closed position, it draws the plunger outwardly, applying a compressive force to the O-ring that causes the O-ring to expand radially outward, sealing the opening into the battery compartment against the intrusion of water or other liquids and securing the battery compartment cover in engagement with the opening.
