Abstract: An electronic parcel delivery system for delivering digital information between computer systems over a network is described. The parcel delivery system includes a server system interposed between a sending system and a receiving system. The server system stores digital information received over the network. The digital information can represent a parcel, document, image, executable software, audio file, etc. The sending system transmits a notification to the receiving system. The notification signifies that the sending system is transmitting the digital information to the server system over the network and that the digital information may be accessible by the receiving system. The receiving system can receive the notification directly from the sending system or through a second server system connected to the network. The server system can receive the digital information directly from the sending system or through a second server system connected to the network.

Abstract: Techniques are provided for using an authentication proxy server for a destination server to authenticate the identity of the user of a client system based on a digital certificate and a user password. The authentication proxy server also cryptographically associates a digital signature with hardware of a particular client system and later authenticates the hardware of the client system based on the digital signature associated with the hardware. When these techniques are combined with authenticating the destination server based on a digital certificate and authentication the encryption of communications between a browser of the a client system and the a destination server, an authenticated identity for an application user may be provided to the application and the need for the application to request and authenticate a user identifier and password is eliminated.

Abstract: Substituted polyphenylenes and methods for producing such substituted polyphenylenes using supported transition metal catalysis are provided.

Abstract: A golf training apparatus is formed of a body of a typically rigid material and includes a head portion corresponding in shape and dimensions to that of a regulation golf ball, and a stem portion, extending from the head portion. Adhesive is placed on a side of the body at the head and the stem portions, allowing the stem portion to attach the body to a support member, while the remaining portion of the body, including the head portion, extends upward and stands unsupported. A golf club can now be brought into contact with the body, and if contact is made between the club head and the first portion, the body will separate from the support member and the first portion will adhere to the club head, indicating the location on the club head where it contacted the golf ball. Based on this information, the golfer can adjust his swing, such that contact with a golf ball will be made at the desired “sweet spot” or other location on the club head.

Abstract: A method and apparatus for providing protection from unauthorized use of messages received by a system is described. The receiving system can receive a message from a sending system, for example, over a network or from local media. The message can be an e-mail message, the contents of a Web page, music, or software, etc. The receiving system stores the digital information in a storage device in a manner designed to conceal the message from unauthorized access. When a user of the receiving system wants to view the message, the digital information is accessed, the message is generated from the digital information and displayed at the receiving system. Use of this generated message is restricted. In another embodiment, this use is limited to outputting (i.e., displaying and producing sound) the generated message at the receiving system. The receiving system cannot copy, modify, save, forward, or capture any portion of the generated message.

Abstract: An electronic mail system is modified to produce a secure delivery system by modifying a user interface of the electronic mail system to present a secure delivery icon and causing the electronic mail system to initiate a secure delivery in response to actuation of the secure delivery icon. The secure delivery uses a delivery protocol different from a protocol provided by the electronic mail system, and the secure delivery icon is presented in addition to a normal delivery icon of the electronic mail system.

Abstract: Systems and techniques are provided for controlling and managing digital assets. These systems and techniques are particularly useful when digital assets are transmitted electronically using, for example, the Internet, as these techniques serve to make the Internet secure for communication and control of digital assets. In addition, they permit dynamic control and management of digital assets, regardless of where the assets reside. Use of these systems and techniques promises to enable new, Internet-based distribution models, and to provide superior insight with respect to the use and status of digital assets. Particular implementations of the systems and techniques permit features such as lifetime control of digital content, multi-level control of digital content (including session encryption, asset encryption, and remote management), and try-before-you buy marketing approaches.

Abstract: An apparatus for monitoring a negative pressure atmosphere, e.g. a regenerative furnace atmosphere during an exhaust cycle, has aspirating facilities for aspirating an atmospheric sample from the negative pressure atmosphere and moving the sample past an analyzer for content analysis thereof.

Abstract: Pneumatic control of flow patterns in regenerators is improved by the use of flow amplifier nozzles.

Abstract: Regenerator packing members are constructed and arranged to form tapered passageways interconnecting regenerator flues to induce transverse flow of gas between flues for increased heat transfer. A preferred embodiment includes parallelepiped bricks arranged in an open basketweave pattern, with spaces between brick ends and side faces defining the tapered passageways.

Abstract: A method and apparatus for the controlling of longitudinal distortion of float glass is disclosed. It is disclosed that longitudinal distortion may be reduced by asymmetric cooling beneath the molten metal bath of a float glass forming chamber.

Abstract: A method and apparatus for reducing longitudinal distortion in float glass is disclosed. A beam or barrier having cross-hatched grooves is installed below the advancing float glass ribbon in a float glass-forming chamber. The barrier acts to divert or diffuse laterally the molten metal which is being drawn by interfacial drag with the bottom surface of the glass. The diffusion evens the heat on the undersurface of the glass and reduces glass distortion.

Abstract: A method and apparatus for the formation of flat glass are disclosed. The invention involves the utilization of transversely inclined barriers in the molten metal bath of a flat glass forming chamber to create asymmetric currents in said bath.

Abstract: Method and apparatus for achieving other than equilibrium thickness of float glass is disclosed. The thickness of the float glass is regulated by applying a rotating, toothed cylindrical member to the upper surface of molten glass as it moves on a molten metal bath. The cylindrical member preferably has teeth in a worm arrangement and is utilized with its axis parallel to a plane normal to the glass surface and extending in the direction of the movement of the glass ribbon.
