Abstract: The present invention addresses the critical needs of publishers seeking to create and publish hypermedia content in electronic form across the wide area networks (“WAN's”) such as the World Wide Web. Toward this end, a client-server development platform is provided for handling the important functions of document authoring, content-based indexing and retrieval of documents, management and control of proprietary assets, and a support for developing form-driven interactive services, all in a manner that is uniquely and seamlessly WAN-integrated.

Abstract: A method for inhibiting diffusion of silicon into a support structure from a component formed of a silicon-containing material, and an assembly formed thereby. The component is supported and contacted by the support structure so as to define a contact interface therebetween. An barrier coating is present on the component and/or the support structure, so as to be disposed at the contact interface to prevent direct physical contact between the silicon-containing material and the superalloy substrate.

Abstract: A valve assembly for use in an animal feeding teat and an animal feeding teat in combination with the above valve assembly. The valve assembly includes a piston shaft with a piston head, a valve head attached to the piston shaft at the end of the shaft opposite the piston head, and a biasing structure co-operable with the piston head, so that in use in an animal feeding teat the valve head is seated to cover a first aperture in the teat and pressure on the piston head against the biasing structure will unseat the valve head and open the aperture.
