Title: A process for the production of biodegradable encapsulated fertilizers
Inventor: MARKUSCH PETER H
IPC: C05G3/00
Filed: 1997-12-11
Abstract: This invention relates to a process for the preparation of polyurethane encapsulated fertilizer particles. This process comprises applying an isocyanate-reactive component to fertilizer particles, and applying an aliphatic polyisocyanate to fertilizer particles in separate steps to form polyurethane encapsulated fertilizer particles. The two reactants may be applied in either order, with the polyisocyanate being first or last.      These two steps may optionally be repeated as many times as necessary to yield polyurethane encapsulated fertilizer particles which contain from 0.5 to 15% by weight of polyurethane, based on the total weight of the encapsulated fertilizer particles. It is also possible to mix the isocyanate-reactive component and the polyisocyanate together to form a mixture which is then applied to the fertilizer particles. These polyurethane coatings which encapsulates the fertilizer particles are biodegradable.

Title: Ceramic membrane for endothermic reactions
Inventor: PRASAD RAVI
IPC: B01J19/24
Filed: 1999-08-30
Abstract: Syngas, a mixture of hydrogen and carbon monoxide, is an intermediate in the conversion of methane to liquid fuels. For certain applications, it is desirable to maintain an H2/CO molar ratio of about 3.      This molar ratio is achieved by steam reforming of methane in accordance with:      CH4 + H2O ~ 3H2 + CO.        To provide the heat required to drive the endothermic steam reforming reaction, a low grade fuel is combusted in a reactor and the heat of combustion conducted to the endothermic reaction. By using an oxygen selective ion transport membrane element to transport the oxygen required for combustion, the formation of undesirable NOx compounds is minimized.

Title: User directed heuristic design optimization search
Inventor: TONG SIU
IPC: G06F17/50
Filed: 1998-07-17
Abstract: A directed heuristic search (DHS) (102) has been developed for an optimization design system. The DHS directs a design optimization process that implements a user's selections and directions, the order and directions in which the search for an optimal design is to be conducted, and how the search is to sequence through potential design solutions (116). In addition, DHS is tractable, in that it records a log (118) of the sequence of design solutions that were evaluated during a particular design optimization search. The user may review this search log, to understand how and why the DHS made design optimization decisions. The user may change search parameter settings in a user defined dependency (114) to change future search patterns for optimal designs.
