Abstract: Multimedia distribution and broadcast systems and related processes are provided for transmitting multimedia contents and control information from a central uplink facility to a remote downlink via a satellite. The system is preferably implemented in order to generate sequences of multimedia that are broadcast from the remote downlink facility to viewers. The display arrangements of the multimedia sequences are varied and customized by each downlink facility using the control information in order to better inform and entertain viewers.

Abstract: An Internet television program guide electronic-mail (e-mail) reminder system is provided. The system allows a user at a multimedia system to order and receive e-mail message reminders of scheduled television events over the Internet. The user can order e-mail reminders after selecting a program from the program listings or by supplying [a program title directly] specific user program preferences without having to consult the program listings. The user can specify when and how often the reminders will be generated and received. If desired, the user can view a list of all currently requested e-mail reminders. Entries can be added to the list or the user can cancel a previously ordered reminder. The user can order e-mail reminders for scheduled pay-per-view programs using the system. The user can also have reminder information periodically updated and available directly on the user's multimedia system.

Abstract: A powder metallurgy method for making valve guides for use in internal combustion engines advantageously utilizes uniaxial side pressing to form compacts. Such compacts are subsequently sintered, formed into a cylindrical shape, and then hollowed to form a valve guide. The valve guides exhibit improved uniformity and density and hardness from end to end of the valve guide when contrasted to powder metal valve guides formed with uniaxial end pressing.

Abstract: A valve guide of alloyed gray cast iron comprising from about 3 to about 3.5 wt. % carbon, about 0.2 wt. % phosphorous maximum, from about 0.35 to about 0.75 wt. % molybdenum, from about 1.8 to about 3 wt. % silicon, from about 0.6 to about 1 wt. % manganese, from about 0.8 to about 1.5 wt. % chromium, balance essentially iron, is heat treated by austenitizing, quenching, and tempering, to obtain a Rockwell C hardness from about 35 to about 45. The microstructure comprises at least about 3% intercellular carbide in a matrix of tempered martensite. Such valve guide exhibits improved wear resistance during use in an internal combustion engine.

Abstract: The present invention provides a system and method for transmitting and receiving data that can transmit data over a plurality of data paths simultaneously and that provides a plurality of transmission queues which enable data transmissions to be continuously prioritized and which do not cause bottlenecking of data. In the preferred embodiments, the present invention comprises a data transmission facility, at least one forward data path, at least one data reception facility, and at least one reverse data path. Data is transmitted in response to a request to transmit data which may be locally generated at the data transmission facility, or may be remotely generated at any of the data reception facilities and transmitted to the data transmission facility through the reverse data path. The requested data is then transmitted from the data transmission facility through at least one forward data path to at least one data reception facility.
