Abstract: It is possible to improve significantly the optical performance of diacetal or DBS-based nucleating or clarifying agents using a co-additive. Haze is a measure of the lack of clarity in a thermoplastic or plastic material. A low level of haze is usually quite desirable, and nucleating/clarifying agents are designed to reduce the degree of haze in a plastic or thermoplastic material. A co-additive may be used in connection with a nucleating/clarifying agents in a polymer or copolymer to achieve even greater results in terms of improved clarity (reduced haze), or in terms of a higher crystallization temperature (Tc) of the polymer. A method for reducing haze in polymer articles using a co-additive composition in addition to nucleating and clarifying agents is disclosed.

Additionally, the fluid catalytic cracking system can include a gas distributor contained near the bottom of the riser in communication with a hydrocarbon feed.

Abstract: A high precision micro/nanoscale machining system. A multi-axis movement machine provides relative movement along multiple axes between a workpiece and a tool holder. A cutting tool is disposed on a flexible cantilever held by the tool holder, the tool holder being movable to provide at least two of the axes to set the angle and distance of the cutting tool relative to the workpiece. A feedback control system uses measurement of deflection of the cantilever during cutting to maintain a desired cantilever deflection and hence a desired load on the cutting tool.

Abstract: An object of the present invention is to create a migration mapping definition based upon computer program changes and use the migration mapping definition to migrate instance data from an older software version format to a newer software version format. A developer uses edit commands, such as mouse commands and keyboard commands, to update a computer program. For example, a software developer may upgrade “Application XYZ” from version 1.0 to version 2.0 in order to include a simpler approach to import images, as well as the ability to import newer image format types. As a developer updates a computer program using edit commands, the edit commands are stored in a migration mapping definition. In turn, the migration mapping definition is deployed, along with the updated computer program, to an end user. The end user then uses the migration mapping definition to migrate instance data generated by the original computer program to instance data that is usable by the updated computer program.
