Title: Remote monitoring of grade crossing warning equipment
Inventor: MOLLET SAMUEL R
IPC: E01B7/20
Filed: 2002-12-19
Granted: 2010-04-06
Abstract: A system (40) and method for remotely monitoring the operating status of railroad grade crossing warning equipment. A sensor (46) generates a signal (48) responsive to the operation of a grade crossing annunciator (42). In one embodiment, the annunciator may be a bell or speaker horn (92) and the sensor may be an accelerometer (99) mechanically coupled to the bell. A wayside controller (52) uses the signal as input for developing information (70) indicative of the operating status of the annunciator. A communications link (74) transmits the information to a location remote from the grade crossing. A system controller (78) located at the remote location may diagnose the information to direct a maintenance center (82) and/or operations center (86) in response to an indication of degraded performance of the annunciator. The communications link may include the Internet and may be used for two-way communication between the remote location and the grade crossing location (22).

Title: Methods for increasing the production of ethanol from microbial fermentation
Inventor: GADDY JAMES L
IPC: C12R1/145
Filed: 2001-07-23
Granted: 2010-07-13
Abstract: A stable continuous method for producing ethanol from the anaerobic bacterial fermentation of a gaseous substrate containing at least one reducing gas involves culturing a fermentation bioreactor anaerobic, acetogenic bacteria in a liquid nutrient medium; supplying the gaseous substrate to the bioreactor; and manipulating the bacteria in the bioreactor by reducing the redox potential, or increasing the NAD(P)H TO NAD(P) ratio, in the fermentation broth after the bacteria achieves a steady state and stable cell concentration in the bioreactor. The free acetic acid concentration in the bioreactor is maintained at less than 5 g/L free acid. This method allows ethanol to be produced in the fermentation broth in the bioreactor at a productivity greater than 10g/L per day. Both ethanol and acetate are produced in a ratio of ethanol to acetate ranging from 1:1 to 20:1.

Title: Sealing method and device for a gas turbine shaft
Inventor: BRUNO VITTORIO
IPC: F01D11/02
Filed: 2002-09-04
Granted: 2010-07-13
Abstract: A method and apparatus for sealing a radial gap (27) between coaxial inner and outer rotating shafts (26, 28) of a gas turbine engine includes using a radial seal (64) as a main seal to seal the gap (27) for a normal engine operation condition, and using an axial seal (70) as a back-up seal for a double seal of the gap. The radial seal (64) provides a seal which meets relatively restrictive leakage requirements for the normal engine operation condition and the axial seal (70) provides a back-up seal which meets less restrictive leakage requirements but is much more tolerant of radial displacement and vibration between the coaxial inner and outer rotating shafts. An engine operable condition is ensured under abnormal conditions, such as bird strikes, in which the coaxial relationship between the inner and outer rotating shafts (26, 28) are affected by unbalancing forces caused by the bird strike, thereby causing a failure of the radial seal.

Title: Method and apparatus for transmission of upstream data in an optical network
Inventor: HORNE DAVID M
IPC: H04B10/272
Filed: 2002-09-27
Granted: 2008-01-22
Abstract: In an optical network that communicates upstream data utilizing a time division multiple access (TDMA) technique, end nodes transmit upstream data on a first wavelength in accordance with a transmission sequence. The end nodes transmit a timing signal on a second wavelength following the upstream data.  The timing signals are reflected by a wavelength selective reflective element to each of the end nodes. The end nodes track the timing signals to determine when to transmit upstream data in accordance with the transmission sequence.  The optical network includes an outside plant node coupled to the system head end with a distribution fiber. The outside plant node is coupled to the end nodes with drop fibers. The outside plant node includes a splitter/combiner and the wavelength selective reflective element. The wavelength selective reflective element reflects the timing signals on the second wavelength and passes upstream and downstream data on other wavelengths.

Abstract: A method and apparatus for producing a discrete particle for subsequent analysis (such as mass spectrometry) or manipulation is disclosed. A discrete particle is generated by a particle generator. A net charge is induced onto the particle by an induction electrode. The particle is delivered to a levitation device where it is then electrodynamically levitated. If the particle is a droplet, desolvation will occur, leading to Coloumbic fissioning of the droplet into smaller droplets. The movement of the levitated droplet(s) can be manipulated by an electrode assembly. The droplet(s), and the charge thereon, can be delivered to a mass spectrometer in one aspect of the invention, providing an ion source for mass spectrometry without the detrimental space charge effects of electrospray ionization techniques. In another aspect of the invention, the levitated particle(s) may be controllably and precisely deposited onto a plate for subsequent analysis by matrix assisted laser desorption and ionization mass spectrometry.

Abstract: A bone cutting guide block has a saw guide surface thereon and has a body shaped to conform to the anterior-medial shape of the proximal left tibia and distal left femur and also to the anterior-lateral shape of the proximal right tibia or the distal right femur. The block is used by placing the curved inner surface adjacent the anterior-medial or anterior-lateral quadrant of either the tibia or the femur and utilizing images from a computer database utilizing an optical tracking system mounted on the cutting block and referencing to the bone to be cut. Utilizing the tracking system, the cutting guide is positioned preferably by hand in the proximal-distal direction to set the depth of the resection. The cutting guide surface is then oriented by hand to the correct varus-valgus and/or flexion-extension angles and pinned to the bone. Preferably, the block is pinned using a single pin in either the correct varus-valgus or flexion-extension position and then the other of the angles not initially selected is set by rotating the block about the single pin. Once the other of the varus-valgus or flexion-extension angles is determined, additional pins are utilized to fix the guide in position for use during the resection of the proximal tibia or distal femur. A second block is provided conforming to the anterior-lateral left tibia and femur as well as the anterior-medial shape of the right tibia and femur.
