Abstract: A configuration for a transport node of a telecommunication system comprises a pair of transparent mux/ demuxs provided at two sites and connected over a high rate span. The T-Muxs provide continuity of all tribs and maintain a lower bit rate linear or ring system through the higher bit rate span. The lower bit rate linear or ring system operates as if it were directly connected without the higher bit rate midsection. For the forward direction of the traffic, the T-Mux comprises a multi-channel receiver for receiving a thetrib signals and providing for each trib signal a trib data signal and a trib OAM&P signal. The data signals are multiplexed into a supercarrier data signal and the OAM&P signals are processed to generate a supercarrier OAM&P signal. A supercarrier transmitter maps the supercarrier data signal and the supercarrier OAM&P signal into a supercarrier signal and transmits same over the high rate span. Reverse operations are effected for the reverse direction of traffic. With this invention, an entire ring system does not have to be upgraded to a higher line rate due to fiber exhaust on a single span. The invention is particularly applicable to SONET OC48/OC-12/OC-3 linear and ring networks and the high rate span could be an OC-192 line.

Title: Process and device for producing pipes as per the uoe-process
Inventor: GROSS-WEEGE JOHANNES
IPC: B21D3/12
Filed: 1997-01-20
Granted: 2005-08-02
Abstract: The invention related to a process for producing pipes, especially large pipes, according to the UOE process, wherein a pipe, after internal and external seam welding, is incrementally calibrated by cold expansion up to half the pipe length. The cold expansion is simultaneously used for straightening. For this purpose, the pipe is clamped at the shortest possible distance in front of an expander head, the free pipe end is flexibly deformed, and the pipe is then cold expanded in a known manner. The prestress force thereby decreases and then, after the release of the clamping and the remaining prestress, the pipe moves incrementally by the amount of and expander step width, up to half of the pipe length. The process is then repeated for the second half of the pipe.

Title: Rubber dam and method of application thereof
Inventor: MURAMATSU TATEO
IPC: E02B7/00
Filed: 1999-01-12
Granted: 2007-04-10
Abstract: A rubber sheet is formed in a bag shape, and a seam portion of the bag-shaped rubber sheet is fixed to a summit portion of an overflow dam. When the bag-shaped rubber sheet is expanded, a rubber dam is raised, thereby damming up water and adjusting the amount of running water. Next, when the bag-shaped rubber sheet which has been expanded is contracted and collapsed, the rubber sheet is supported by pipes, which extend substantially horizontally from the summit portion of the overflow dam toward the downstream side at a predetermined distance from each other.      For this reason, the rubber sheet hangs down with its own weight and with the weight of water running downstream so as to droop down between the pipes. As a result, a rubber dam that does not bulge at the downstream side is obtained.

Title: Fdd forward link beamforming method for a fdd communications system
Inventor: RYAN DAVID JAMES
IPC: H04B7/06
Filed: 1999-02-23
Granted: 2002-12-31
Abstract: A highly bandwidth-efficient communications method is disclosed, to maximize the signal-to-interference-noise ratio (SINR) of transmissions from a base station to a remote station in a wireless communications system. The method is used for base stations that have a plurality of antenna elements that are capable of spatial beam steering by altering the relative phase of transmission of signals from the respective elements. The method of the invention is based on providing calibration frames that sequentially transmit calibration bursts from the respective antenna elements for a particular destination remote station. The calibration bursts include a plurality of tone frequencies arranged in a distinctive orthogonal frequency division multiplexed pattern unique to the base station. The unique pattern enables a remote station to distinguish the base station's bursts from other signals present in a crowded area. The distinctive orthogonal frequency division multiplexed pattern can be a Hadamard code pattern, for example. The plurality of calibration bursts are part of a transmission frame having a reference phase. The remote station receives the calibration bursts and measures values related to the relative phase difference between the calibration bursts and the reference phase. The remote station also measures the SINR of the received bursts. The measured values are then prepared as a sampling data message that is transmitted by the remote station back to the base station. The base station then calculates therefrom a beam steering correction to modify the relative phase difference. This beam steering correction is then applied to traffic bursts that are respectively transmitted from the plurality of antenna elements at the base station, to steer the plurality of traffic bursts toward the remote station. The beam steering correction steers the traffic bursts to maximize the signal-to-interference-noise ratio (SINK) of the traffic bursts at the remote station.
