195 results about "Regenerative process" patented technology

In applied probability, a regenerative process is a class of stochastic process with the property that certain portions of the process can be treated as being statistically independent of each other. This property can be used in the derivation of theoretical properties of such processes.

Self-regenerative process for contaminant removal from liquid and supercritical CO2 fluid streams

A method for the decontamination of fluid (liquid or supercritical) carbon dioxide fluid, especially of hydrocarbon contaminants, down to <=100 ppb concentration are described. The critical component is a high silica zeolite, preferably a high silica Y-type zeolite, ZSM-5 or a high silica mordenite, which in a variety of physical forms is capable of decontaminating such fluid CO2 to <=100 ppb, <=10-50 ppb, or ~1 ppb, without being detrimentally affected by the supercritical operating environment. The high silica zeolite may be produced by the removal of alumina from a natural or synthetic zeolite while retaining the desirable zeolite structure, to a silica:alumina ratio of from 20-2000:1. Preferably the zeolite is disposed in separate quantities in at least two vessels, which operate alternately. A portion of the purified product from the operating vessel is directed to the other vessel and there used to remove accumulated contaminants from that vessel's zeolite. The process thus provides self-regeneration, in that regeneration of one vessel occurs while the other vessel decontaminates contaminated fluid carbon dioxide, so that use of the two can be alternated for substantially continual production of purified fluid carbon dioxide. The invention provides purified fluid carbon dioxide used in manufacture of such products as high purity electronic, optical, prosthetic or similar products or polymers or pharmaceuticals or in beverages.

Dietary regimen of nutritional supplements for relief of symptoms of arthritis

This invention is directed to a dietary regimen and a unique combination of nutritional supplements and a method. More specifically, this invention is directed to a unique combination of nutritional supplements which provides symptomatic relief from arthritis. The unique combination of nutritional supplements of this invention is believed to function by both increasing the available (effective blood level) of anti-inflammatory agents and promotion of the healing/regenerative process in the effected joints, thus, producing unexpected and lasting symptomatic relief from the debilitating effects of both osteoarthritis and rheumatoid arthritis. The essential nutritional supplements of the dietary regimen of this invention are as follows: (a) gamma linolenic acid (unrefined), hereinafter "GLA"(b) a mixture of eicosapentaenoic acid and docosahexaneoic acid, hereinafter collectively "EPA"(c) a mixture of chondroitin sulfate, N-acetyl glucosamine sulfate, glucosamine sulfate and manganese aspartate, hereinafter collectively "CHONDROX"The regimen is adjusted based upon the weight of the individual, and once symptomatic relief is achieved, the individual remains essentially free from the debilitating effects of arthritis so as long the daily regimen is faithfully followed.
