Title: Food dressing
Inventor: BIALEK JADWIGA MALGORZATA
IPC: A23L1/00
Filed: 1996-09-18
Abstract: Process for the preparation of water continuous emulsions, containing 10 to 60 wt.% of dispersed oil. The emulsion contains protein obtained from egg, milk, vegetables or fruit, but no substantial amounts of polysaccharide thickeners. The process comprises the following steps (not necessarily in the indicated order): a) dispersing or dissolving the protein in either an aqueous phase or an oil phase; b) mixing the aqueous phase and the oil phase so that a coarse emulsion comprising oil droplets results; c) homogenising the emulsion until the [D3,2] size of at least 95 % of the oil droplets is less than 5 µm; d) acidifying the emulsion until a pH 3.5 to 4.5 is attained; e) adding, under shear conditions, an aqueous electrolyte solution to the emulsion having a temperature of 10 to 55 °C. The electrolyte addition causes flocculation of the emulsion. This flocculation increases the viscosity and imparts an attractive texture to the food dressing.

Title: Compounding assembly for nutritional fluids
Inventor: MARTUCCI JAMES P
IPC: G05D11/13
Filed: 1997-11-19
Abstract: A mixing assembly which transfers a num-ber of nutritional fluids from individual source containers into a collection container while non-invasively sensing the type of fluid being trans-ferred is provided. The mixing assembly utilizes a transfer set to establish fluid communication be-tween the source containers and the collection con-tainer. A sensing assembly is configured to non-invasively sense a number of the types of fluid flowing through the transfer set to help to prevent improper mixing. For other fluids for which the sensing assembly alone may not be able to distin-guish with the desired accuracy, the mixing device utilizes a method to approximate the flow rate of that fluid with the flow rate also providing an in-dication of that type of fluid. By combining the output of the sensing assembly with the flow rate determination, additional fluids can be identified.

Title: Interactive multiple bladder seating comfort adjustement
Inventor: LONG BRUCE T
IPC: B60N2/90
Filed: 1997-12-12
Abstract: A system of inflatable air cells is constructed and installed in a seat at locations that are strategic to the comfort of the user. The air cells are connected to a pump (134) trough a manifold (130) which sequentially connects each cell independently to the pump (134). The manifold (130) controls the flow of fluid in the air cell distribution system by means of a system of valves (130a-130h), and senses the pressure in each cell by means of a transducer (139). A microcomputer (128) is programmed with data representing a desired comfort level for each of the air cells. By sequentially activating individual manifold valves (130a-130h), a pressure signal from the transducer (139) can be generated for each cell. The pressure signals are received by the microcomputer (128) and are correlated with the predetermined comfort data to generate a control signal which activates the pump (134).
