  • Patent number: 5247650
    Abstract: A method and apparatus are disclosed which allows a plurality of dissimilar simulation systems to act in a cooperative manner such that they may act to provide a single overall simulation of a system. The system to be simulated is partitioned into these simulation systems and subsequently these systems are networked and synchronized. This interaction of these dissimilar simulation systems is accomplished by a simulation tool which allows a simulation system to route messages to other systems, synchronizes the operation of all simulation systems, allows partitioning elements to be stored and downloaded to these systems, and allows each simulation system to utilize its own native programming language during the creation of the single system simulation associated therewith.

They have non-caloric food values, with good organoleptic characteristics, are substantially resistant to intestinal absorption and do not appreciably hydrolyze in the digestive tract. Suitable polysaccharides are preferably selected from xanthan gum, guar gum, gum arabic, aliginates, cellulose hydrolysis products, hydroxypropyl cellulose, starch hydrolysis products, casein, Karaya gum and pectin. C.sub.5 and C.sub.6 oligosaccharides of n=3-10 units are preferred. The polysaccharides are transesterified with fatty acid methyl esters to create PEPs of a degree of esterification determined for each polysaccharide.

  • Patent number: 4558154
    Abstract: A novel synthesis of methacrylic acid and methacrolein from isobutylene oxide is provided. This method includes contacting isobutylene oxide with a catalyst, preferably a heteropolyacid catalyst, in the presence of oxygen. Using this method, isobutylene oxide conversion is nearly 100% complete. Depending upon the reaction temperature selected, yields of up to about 60% methacrolein and up to about 12% methacrylic acid may be obtained. A simple, inexpensive high yield process is thus provided for producing reaction mixtures containing methacrylic acid and methacrolein.
