Filed:

Feb 20, 2001

Appl. No.:

09/788967

Inventors:

Jeffrey A. Gates - West Chester OH
Michael S. Sharp - Brookville IN

Assignee:

Cognis Corporation - Gulph Mills PA

International Classification:

B01D 3315

US Classification:

210782, 525444, 528302, 528303, 528306, 528307, 528308, 5283086

Abstract:

A polyester is provided which facilitates the separation of blood into light and heavy phases via centrifugation in a blood collection vessel. The polyester is useful as a component of a partitioning composition formulated to have appropriate specific gravity to be positioned intermediate the light and heavy blood phases during centrifugation. The polyester composition can be prepared with relative ease compared to prior art polyesters useful in blood partitioning compositions. The polyesters of this invention comprise a dicarboxylic acid member, a polymeric fatty acid, a diol member and a moiety having at least one polymerizable carbon-carbon double bond and at least one functional group capable of reacting with the ends of the polyester chain. The polyesters have a lower viscosity when synthesized and are later cured to increase their viscosity to the desired level.

Assignee:

Cognis Corporation - Ambler PA

International Classification:

C08F008/14

US Classification:

525386, 5253273

Abstract:

Powder coating compositions having reduced volatility and improved processibility compared to conventional powder coatings consist essentially of a copolymer having pendant functionalities or pendant groups capable of reacting with a dicarboxylic acid such as the glycidyl groups of glycidyl acrylate or methacrylate copolymer and a cross-linking effective amount of a dicarboxylic acid. The reaction of the above pendant groups and the dicarboxylic acid cross-links or cures the powder coating after application to a substrate. The dicarboxylic acids according to the invention eliminate the need for a third component which is a flow control agent which improves the processibility of a two-component powder coating. The dicarboxylic acids according to the invention have a sublimation temperature great enough to decrease or prevent their vaporization during the curing of the powder coating and have a melting point low enough to impart improved flow properties to the powder coatings.

US Classification:

463/042000, 434/037000

Abstract:

According to various exemplary embodiments, a content-providing system for a flight simulator suitably includes a gateway having an interface to a digital network and at least one host computer system executing a server portion of the flight simulator program such that the gateway is operable to receive a request for a connection to the server portion from a user executing a client portion of the flight simulator program over the digital network, and to establish a connection between the client portion and the server portion such that primary processing for the flight simulator takes place at the server portion, and such that interface updates are processed at the client portion.
