Title: Ranging process for point-to-multipoint communication systems
Inventor: MUSIOL TORSTEN
IPC: H04J14/08
Filed: 1995-10-20
Abstract: A ranging process is disclosed for point-to-multipoint communication systems having a central station (OLT) and several terminals (ONU) connected to the central station (OLT) by a network, in particular a passive optical network. Each terminal sends a pseudo-noise sequence (ONU-PNS-TX) on a carrier outside the data transmission band, the pseudo-noise sequence is received with a delay (ONU-PNS-RX) by the central station (OLT) and is correlated with a pseudo-noise sequence (OLT-PNS) identically generated in the central station (OLT). The two-way delay to the terminal (ONU) is determined from the extreme value of the correlation function and the required delay between the burst received by the terminal and the burst sent by the terminal is derived from the two-way delay. In order to create a communication system in which the terminals have a as simple as possible ranging hardware, the ranging sequence is a binary sequence whose autocorrelation function has an extreme value at the zero point. The relative phase position between the received ranging sequence (ONU-PNS-RX) and a clock signal (OLT-CLK-SEQ) derived from the data rate (OLT-CLK-DATA) is at first determined at the central station (OLT) and the ranging sequences of the terminal and central station are then correlated in phase.

The telescoping section provide a more compact line and easier access to the complex equipment downstream of the die. The extrudate from the die passes down into the pond (72) and then through an orifice (74) in a hood (75) projecting from the chamber into a lower level portion of the pond (78) exposed to atmosphere. The hood also includes a tractor drive (88) to push the extrudate through the underwater orifice. The hood and its contents are accessible through the atmospheric pond. A tractor haul-off and the tractor drive in the hood are the only extrudate drives between the calibration equipment and atmosphere. The higher level of the pond (72) within the chamber downstream of the dam is controlled by a valve in turn controlling the output of a pump. The valve control senses the pond level and operates independently of the vacuum controls. <IMAGE> <IMAGE>A horizontal vacuum extrusion line includes a fixed bulkhead (23), a die (24) inside the bulkhead, a telescoping vacuum chamber section (27) and fixed chamber sections (28,29).

Patent AU-4658285-A (AU)
Title: Steel tension rod production and the product thereby
IPC: E04C5/16
Filed: 1985-08-23
Abstract: To produce threaded steel tension members, steel is used with a C-content of 0.50 to 0.80%, preferably 0.75%, a Si-content of 0.20 to 0.50%, preferably 0.25%, and a Mn content of 0.30 to 0.80%, preferably 0.60%. Exiting from the rolling heat at the outlet side of the finishing stand after hot rolling, the tension member or rod is subjected to surface quenching by a cooling medium, preferably water, so that the steel in a rim zone R1 is transformed immediately and completely into martensite, while the heat content remaining in the core zone K1 does not effect a tempering of the martensite rim zone during the subsequent cooling beyond the range of the intermediate stage. Steel tension members of this type have a high ductility and toughness at a high yield limit and high strength, they are corrosion-resistant to a great degree and have a wear resistant surface which makes them particularly suitable for threaded tension rods in which the threads are produced either by a cold forming operation or hot rolled ribs.

Title: Method and apparatus for d.c. offset correction in digital-to-analog converters
Inventor: WALKER BRETT CHRISTOPHER
IPC: H03M1/66
Filed: 1999-06-29
Abstract: A method and apparatus for adaptively correcting D.C. offset errors imposed upon signals in a communication device. The present invention includes a feedback loop correction circuit and method for measuring and reducing D.C. offset errors imposed upon analog transmission signals by transmit digital-to-analog converters (DACs) and associated analog reconstruction filters. A digital feedback loop is used to remove the D.C. offset errors from the analog transmission signals prior to transmission. In the preferred embodiment, the digital feedback loop includes a pair of analog-to-digital converters, a digital D.C. offset correction circuit, and a pair of adders. The transmission signals are digitized, filtered, and digitally processed by the correction circuit to generate offset correction signals that are equal to the undesired D.C. offset error present in the transmission signals. The correction signals are added to the digital input baseband signals thereby removing the undesirable D.C. offset errors from the transmission signals. In one preferred embodiment, the analog-to-digital converters comprise differential comparators that generate digital signals representative of the signs of the analog transmission signals. The digital D.C. offset correction circuit processes the digital signals output by the differential comparators using a selected digital signal processing technique. In one embodiment, the offset correction circuit uses a "sign bit" digital signal processing technique whereby the sign bits generated by the differential comparators are continuously integrated. The preferred embodiment of the present invention uses an MSB technique whereby sign characteristics of both the digital baseband signals and associated transmission signals are analyzed to produce the feedback correction signals. In accordance with this technique, integrators are disposed to measure zero crossing time delays between the baseband signals and the filtered signals. The zero crossing time delays are measured by analyzing the relative signs of the baseband signals and the filtered signals. The zero crossing time delays are used in the preferred embodiment as an estimate of the D.C. offset errors present in the transmission signals.

Title: Friction driven flexible, endless conveyor belt
Inventor: COLDING-KRISTENSEN HOLGER
IPC: B65G21/18
Filed: 2000-05-31
Abstract: An endless conveyor has a driven drum that rotates about its axis. A flexible band forms a helix by being wrapped around the drum. A fixed helical support supports the outer edge of the band. A secondary conveyor moves an endless series of stacking blocks. The stacking blocks are in frictional engagement with the drum to transfer driving forces from the drum to the blocks. The stacking blocks also keep the turns of the flexible band spaced apart by a distance equal to the height of the blocks. The secondary conveyor includes guides at both the top and bottom of the drum to guide the stacking blocks into and out of engagement with the inner edge of the flexible band. The stacking blocks are in slip-free and backlash free engagement with the inner edge of the flexible band, and the frictional engagement between the stacking blocks and the drum permits the stacking blocks to be displaced both axially and circumferentially on the surface of the drum.
