Abstract: The present invention relates to a mixture of at least two different dispersing agents, an aqueous dispersion containing a UV absorber selected from benzotriazoles, benzotriazines and benzophenones and a mixture of at least two different dispersing agents and a method for reducing the differential pressure in the static dyeing process.

Abstract: A method, apparatus, system, and signal-bearing medium that, in an embodiment, determine whether a user at a first client has a chat session already active at a second client with a third client in response to a request for initiation of a chat session for the user at the first client. If the user does already have a chat session active, the third client is notified that the first client replaces the second client in the chat session. Then chat data from the second client is copied to the first client, and a disconnect message is sent to the second client from first client. In various embodiments, the determination may be made by sending a query to a plurality of clients connected via a network or by sending a query to a server that serves the first client, the second client, and the third client. The copied chat data, which may include messages sent between the second client and the third client, is presented at the first client.

Abstract: The disclosure relates to an apparatus and method for controlling a system used to pasteurize food products such as milk, orange juice and raw eggs. Such system has components including at least one product tank, a pump for flowing a product through the system, a flow diversion device and a heat exchanger. The apparatus has a programmable logic controller linked to at least one component and also includes a display panel having (a) a depiction relating to one of the components, and (b) an input device such as a touch-pad type pushbutton connected to the controller for controlling a component. There are several depictions displayed in sequence and when a depiction is displayed, the input device associated therewith is also displayed and may then be actuated. After pasteurization, a batch report is printed. Vitamin injection is optionally available.

Abstract: The improved milk pasteurizing control apparatus is of the type having a flow diversion valve controller in an enclosure with a door, panel or the like required to be sealed on the outside of the enclosure by a regulatory official. Such seal is applied only after the official is satisfied that the controller and its control routine is operating properly. The improvement includes a controller with a computer chip for executing a control routine programmed in the chip. A barrier, overlay or other obstructing technique within the enclosure "blocks" access to the chip program and prevents alteration of the routine. If the exterior seal is broken (to perform certain types of maintenance, for example), the door may be re-sealed by the official without again testing the entire control routine.
