Abstract: The system allows for the allocation of email addresses to almost every possible person within a country, and allows for easy lookup and/or addressing of messages whether by email, telephone, mail or fax to those subscribers. It makes use of a combination of the subscriber's telephone number and an alphabetical component chosen from their name, for individuals, or an alphabetical description of a department within a business, together with a database server that stores information about each subscriber, and their preferred mode of delivery. The system requires users to create or modify their primary account by a telephone interface, as the system allows for delivery of email messages to subscribers by telephone, mail or fax, to those subscribers who do not have access to a computer and thus access to software to read their emails.

Abstract: A rotary sliding closure unit for use in a liquid melt container extends inwardly through the jacket of the container and into the lining thereof to selectively block and unblock a pouring opening of the container. The unit includes a stationary refractory plate positioned within the lining and having therethrough a flow passage in communication with the pouring opening, and a rotary refractory plate positioned in sliding abutting contact with the stationary refractory plate and having therethrough at least one flow passage to be selectively moved into and out of alignment with the flow passage of the stationary refractory plate. The two refractory plates have complementary abutting relative sliding surfaces located within the interior of the jacket of the container. A stationary tube member extends through the jacket and into the lining and has an inner end grasping the stationary refractory plate.
