Patent CA-2213013-A1 (CA)
Title: Combination motor/pneumatic driven train brake pipe pressure exhaust valve
Inventor: BEZOS ANGEL P
IPC: B60T13/66
Filed: 1997-08-13
Abstract: A valve device is used to reduce the air pressure in a brake pipe disposed on a railroad car in a train consist at a location in the train consist remote from the locomotive of the train consist.  The valve device defines a primary supply passage, a branch supply passage and an exhaust passage.  The primary and branch passages communicate with the brake pipe.  All of the passages communicate with an elongated bore defined within the valve device.  The valve device includes an adjustable first valve, a second valve, an electric motor drive and an pneumatic drive.  The adjustable first valve and the second valve are both part of an elongated valve body member that can move reciprocatingly within the elongated bore.  The adjustable first valve is used to vent air pressure from the brake pipe via the primary and exhaust passages at various rates of discharge.  The rate of discharge is in proportion to the extend the adjustable first valve is commanded open.  The electric motor drive responds to a drive signal for a service brake pipe air pressure reduction through which it opens the adjustable first valve, but not the second valve.  The second valve is used to quickly vent air pressure from the brake pipe via the branch and exhaust passages.  The pneumatic drive responds to an actuating signal for an emergency brake pipe air pressure reduction through which it fully opens the second valve thereby also fully opening the adjustable first valve.
Patent CA-2213764-A1 (CA)
Inventor: KLEMENSKI RICHARD S
IPC: B61L15/00
Filed: 1997-08-20
Abstract: A  radio-based  system  for  a  train  including  a  lead transceiver unit and multiple remote transceiver units.  The lead  transceiver  unit  initiates  a  command  by  sending  a command message.  Each of the remote transceivers receiving the command message transmits a reply message which repeats the command message and contains the status of the sending remote.   Remote   transceivers   not   receiving   the   lead transceiver's  transmitted command message, but receiving  a reply message  from one  of  the  other  remote  transceivers, transmit a reply message containing the remote's status. The lead transceiver detects whether reply messages are received from the remote transceivers and may transmit a request in response. One or more remote transceivers may store and re-transmit reply messages from other transceivers in response to the request.

Patent CA-2219079-A1 (CA)
Inventor: HOGEBOOM JOHN GORDON
IPC: H03L7/089
Filed: 1997-10-22
Abstract: A phase-locked loop (PLL) includes a voltage controlled oscillator (VCO), a charge pump, a phase detector and a frequency detector. The phase detector detects the phase difference between an incoming signal and a VCO signal. The frequency difference between the incoming signal and a reference signal is detected by the frequency detector separately from the phase detector. During the process of attaining phase lock, the phase and frequency detectors operate simultaneously. The VCO signal is phase-locked to the incoming signal when it is present. When the incoming signal is absent, the VCO maintains a frequency close to an intended bit rate by frequency locking to a multiple of the reference signal. It, thus, avoids extreme system behavior and greatly assists rapid reliable phase lock when the incoming signal is applied following a period when it is absent. The PLL is analog for simplicity, low power, and the ability to achieve the finest possible phase resolution, while the frequency lock mode is digitally controlled for high parametric insensitivity and ease of disabling to minimize power consumption and jitter once phase lock is attained. The frequency detector includes two counters for counting the VCO and reference signals. The frequency detector inhibits either of the counters as needed to force them both to count at the same rate and uses inhibit pulses to control a separate charge pump connected directly to the integration capacitor of the PLL. The frequency detector can be easily added to a wide range of charge pump PLLs.

Title: Telomere maintenance assays
Inventor: WELLINGER RAYMUND J
IPC: C12Q1/68
Filed: 1997-05-02
Abstract: The strand of telomeric DNA that runs 5' to 3' towards a chromosome end is typically G-rich. Due to the properties of conventional DNA polymerases, telomerase-generated tails of this G-rich strand are expected on only one end of individual linear DNA molecules. In Saccharomyces, TG1-3 tails are detected on chromosome and linear plasmid telomeres late in S phase. Moreover, the telomeres of linear plasmids can interact when the TG1-3 tails are present.  Molecules were generated in vitro that mimic the structures predicted for telomere replication intermediates. These in vivo generated molecules formed telomere-telomere interactions similar to those on molecules isolated from yeast but only if both ends that interacted had a TG1-3 tail. Moreover, TG1-3 tails were generated in vivo in cells lacking telomerase. These data suggest a new step in telomere maintenance, cell cycle regulated degradation of the C1-3A strand which can generate a potential substrate for telomerase and telomere binding proteins at every telomere.
