Abstract: An electric dust-collection unit includes needle electrodes for charging particulates within the air caused by corona discharges around their tips. Collector cells (collector electrodes) are arranged in a tubular shape corresponding to the needle electrodes for attracting and collecting the charged particulates by static electricity.      Deflecting electrodes are arranged to be inserted within the collector cells to impart a deflecting force on the charged particulates in the direction of the collector cells. The deflecting electrodes are in the form of a hollow column including a forward plate section having a mounting hole for fitting and retaining the needle electrodes. The deflecting electrodes also include side plate sections facing the collector cell at a prescribed distance. The needle electrodes are fixed on the forward plate sections so their tips protrude from the surface of the forward plate sections while their bodies are firmly inserted in the mounting hole.

Abstract: A regulating valve device is provided for utilization with an end-of-train unit in order to reduce a train brake pipe pressure from the rear end in accordance with a pressure reduction initiated at the locomotive on the front end.  A stepping motor under control of a microprocessor controls the compression of a spring to establish a target pressure corresponding to a pressure command signal transmitted from the locomotive to the end-of-train unit.  The service exhaust valve device regulates the brake pipe pressure to the target pressure corresponding to the spring compression set by the stepping motor and includes  an arrangement for overriding the motor control in the event of a fault condition that prevents the motor from resetting the spring to its initial compression when it is desired to recharge the brake pipe to release a brake application.

Abstract: The invention provides for a method for transporting a SONET formatted asynchronous transfer mode (ATM) signal and/or a synchronous transfer mode (STM) signal on a line switched ring over a unidirectional path. The SONET formatted ATM signal comprises cells mapped into a STS-Mc or MxSTS-1s while the STM signal comprises STS-1s/VTs mapped STS-W. A unidirectional line switched ring is provided for transporting the STM STS-W using a unidirectional path switched protection protocol and the ATM STS-Mc using a unidirectional line switched protection protocol. A ring node comprises input and output ring interfaces, an STS management block, an ATM cell management block, and a non-ATM payload management block. The STS management block routes the traffic to the ATM cell management block and to the non-ATM payload management block, according to the traffic type. The STS management block also provides the UPSR protection for the STS-is and ULSR protection for the STS-Mc. The ATM cell management block maps the add ATM cells received from the ATM ports into the STS-Mc signal, and delineates the cells from the STS-Mc to present them to the ATM ports. The non-ATM payload management block routes STM VTs or STS-1s to/from the non-ATM ports.

Abstract: Methods for determining quantities of nucleic acid sequences in samples include the steps of amplifying a plurality of known quantities of a nucleic acid sequence in respective calibration samples and an unknown quantity of a nucleic acid sequence in a test sample, in parallel, during a time interval. These samples may be amplified using an isothermal amplification method such as Strand Displacement Amplification (SDA), or a thermal cycling amplification method such as Polymerase Chain Reaction (PCR), for example. Indicia of the quantities of a nucleic acid sequence being amplified in the calibration and test samples are then measured using conventional techniques, at measurement points in the time interval. Steps are then performed to determine for a first potential cutoff level, a corresponding first set of time points in the time interval at which the indicia of the quantities of a nucleic acid sequence being amplified in each of the calibration samples equal the first cutoff level. This step is then repeated for each of a number of different potential cutoff levels so that respective sets of time points in the time interval can be obtained for each potential cutoff level. According to a preferred aspect of the present invention, a step is then performed to determine, relative to a statistical criterion, which of the sets of points in the time interval better satisfies thestatistical criterion against the known quantities of a nucleic acid sequence in the calibration samples. A quantity of a nucleic acid sequence in the test sample is then determined based on the set of points determined to better or best satisfy the statistical criterion. The accuracy of the determination can also be improved using a relatively large number of potential cutoff levels.
