摘要:
Disclosed is a convertible article of furniture. The article includes a pair of side rails, with braces formed along an intermediate extent of the side rails. A series of pivotal support bars are also positioned along the pair of side rails. Forwardly and rearwardly located legs are included for supporting the side rails above the ground. The legs are pivotally related to the side rails. The article also includes a series of shelves, with each shelf being pivotally mounted between the pair of side rails. As such, the support bars can be used to selectively support the shelves at an angle relative to the side rails. Alternatively, the shelves can be supported by the braces such that the shelves are aligned with the side rails.

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.

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.

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. The server system can include a web page that the receiving system can access to obtain the stored digital information. The notification can include a resource locator that addresses the Web page on the server system. The Web page can request valid authentication of the receiving system before granting access to the digital information. Delivery of the digital information can be canceled by the sending system after the sending system transmits the digital information to the server system until the receiving system uses the digital information.

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.

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.

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.
