IPC: H04B7/185

Abstract: A multibeam communications satellite has direct links with at least one other satellite. The satellite's repeater operates in the bent-pipe mode and can provide service to users independent of signal content, format and protocol. Each incoming electromagnetic (radio) beam received by the satellite contains at least one channel of information, and each channel is divisible into subchannels. Naturally, each subchannel is of a bandwidth which is less than the bandwidth of the channel from which the subchannel was derived. The other satellite has outgoing beams that complement the first satellites incoming beams. Generally, both satellites have processors on board designed to interbeam-switch at the subchannel level. (However, a description is given also of an instance where one or the other satellites may not have subchannelizing capability and limited use may be made of the invention). The satellites are linked by an intersatellite link carrying information on a channel consisting of subchannels constituted from several incoming channels. Therefore, an outgoing beam from the second satellite can contain a channel having information combined from several incoming channels to the first satellite and the channel information on any incoming electromagnetic (radio) beam can be delivered at the subchannel level to several output beams from the second satellite. The system can operate in a broadcast mode whereby information at the subchannel level can be distributed simultaneously (i.e. in parallel) to several outgoing electromagnetic (radio) beams. The intersatellite link is treated as any other beam (incoming or outgoing, as the case may be), although its operating wavelength may be different from the operating wavelengths of the beams having terrestrial origin or destination. For example, the intersatellite link could be at microwave, optical or some other suitable frequency. The basic concept may be extended to a system supporting multiple intersatellite links, e.g. links in both directions between the two satellites or, in some circumstances, among a constellation of more than two satellites.

Abstract: The invention is a method of in-line addressing, for both matched and non-matched mail, comprising a number of steps which begin with the generation of document data in a data processing system and then transmitting that document data to a document printer. The document data is printed, at the document printer, onto a substrate which is subsequently fed to an accumulator. Additionally, address data is generated in the data processing system and transmitted to an envelope printer where the address data is printed to one or more envelopes. The envelope printer is capable of printing a return address, a destination address, and a bar code in respect of the destination address upon the envelope. The address data can be merged with graphics data so that the envelope printer is further capable of printing graphics on the envelope. Once at the accumulator, predetermined batches of one or more sheets of the printed substrate are fed into a sheet folder. The sheet folder folds the predetermined batches and then subsequently feeds the folded batches to the insert feeder. The folded batches are inserted into the printed envelopes to form a mail piece which is then transported to a mail processing apparatus; in an alternative embodiment, the envelopes can be printed upon after stuffing.  Taken together, the sheet feeder, accumulator, sheet folder, and insert feeder comprise a folder/inserter system The envelope throughput is timed to match batch throughput of the folder/inserter system.

Title: High frequency heating device which is safe when its exterior is removed
Inventor: HARADA KEIJI
IPC: H01H9/22
Filed: 1997-07-17
Granted: 2000-09-19
Abstract: A high frequency heating device according to the present invention has a switching member screwed into a screw hole formed in a flange and thus fixed to the exterior.  When the exterior is fixed to the body, a through hole formed at that portion in the rear plate of the body through which the switching member passes is too large for the switching member.  Thus, while switching member is fixable to the exterior, the switching member cannot be fixed to the body onto which the exterior is not mounted.  Thus, a high frequency heating device can be provided, wherein an exterior switch more surely keeps the power supply circuit open when the exterior is removed.

Granted: 2003-04-15
Abstract: The present invention is an integrated process and apparatus for supplying at least a portion of the reducing gas feedstock to a reduction reactor, such as a reactor for the direct reduction of iron, wherein the reducing gas contacts a feed material at a mean operating gas pressure and effects reduction of the feed material to provide a reduced product.          The integrated process includes gasifying a hydrocarbonaceous feedstock in a partial oxidation reaction to produce a synthesis gas which comprises hydrogen, and carbon monoxide at a pressure substantially greater than the mean operating gas pressure in the reduction reactor. The synthesis gas is expanded to lower its pressure to substantially the mean operating gas pressure in the DRI reduction reactor to thereby form the reducing gas feedstock at the pressure conditions used for the DRI reaction. The lower pressure reducing gas mixture generated by the expansion is introduced into the DRI reactor as part or all of the reducing gas requirement for the direct reduction of iron.

A layer 3 address may be extracted from a layer 2 frame, and the layer 3 address information may be used to route a data packet over a packet-switched network according to the service classes, feature sets, and/or CUGs selected. At the destination, the layer 3 data packet may again be enclosed in a layer 2 frame with a DLCI indicating the service classes, features sets, and/or CUGs. Because the use of conventional permanent virtual circuits (PVCs) is not required in aspects of the invention, new methods of measuring and managing network traffic are presented.
