Abstract: Oil-in-water dispersions of .beta.-carotene and other carotenoids that are stable against oxidation, even in the presence of polyphosphates, especially sodium hexametaphosphate. These oil-in-water dispersions are typically prepared by contacting a water-dispersible beadlet comprising at least about 5 % colloidal carotenoid with the water phase to form droplets of the carotenoid that are in intimate contact with sufficient oil phase such that the carotenoid is stable against oxidation, even in the absence of an effective antioxidant such as ascorbic acid. The oil-in-water carotenoid dispersions of the present invention are especially useful in dilute juice beverages for providing vitamin A fortification and color, as well as other oil/water food and beverage products where vitamin A fortification and/or color are desired.

Title: Automatic sample testing machine
Inventor: FLENDER GREGG
IPC: G01N35/00
Filed: 1997-02-12
Abstract: An automatic sample testing machine for testing samples stored in test cards.  The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A  vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles. The test sample positioning system moves the tray to a cutting and sealing station and then to an incubation station and loads the cards one at a time into a carousel within the incubation station. A test card transport station transports the test cards from the incubation station to an optical reading station, where optical measurements (e.g., transmittance and/or fluorescence optical testing) is conducted on the wells of the card. When the card has been read, it is either moved back to the incubation station for additional incubation and reading or transferred to a stacking card disposal system when the reading is complete.

Title: A coating apparatus for applying coating material
Inventor: URSCHELER ROBERT
IPC: B05C11/10
Filed: 1998-02-27
Abstract: A coating apparatus is disclosed for applying coating material onto a moving surface. The apparatus includes a housing (16A) which defines a chamber (18A) for the reception therein of the coating material (12A). The housing (16A) also defines an exit slot (20A) for the passage therethrough of the coating material (12A) from the chamber (18A). A shear applying device (28 A-G) is disposed within the chamber for applying shear to the coating material prior to application of the coating material onto the surface (14A). The shear reduces the viscosity of the coating material and maintains a reduced viscosity of the coating material prior to application of the coating material onto the surface so that uniform flow of the coating through the exit slot taken in a cross-machine direction is facilitated.

Title: Third party management platforms integration
Inventor: BAKER STEVE
IPC: H04L12/24
Filed: 1998-07-31
Abstract: In a method of importing data into a data processing system from a third party platform, for each physical object an interface object having a canonical form mappable to an underlying, externally invisible form in said data processing system is first created. The interface object has a set of permissible extensions mappable to said externally invisible form. New interface objects can be added by deriving new mappings from said extensions. The data processing system is thus decoupled from the third party platform so that the data processing system can easily interface with multivendor products.
