20090011913 | Tire for material treatment system - The invention provides a tire and a roll wheel assembly used to crush material in a pulverizer including a generally toroidal body having a crushing surface on the outer periphery thereof. The crushing surface is configured and adapted to contact and crush the material within the pulverizer. At least one beveled surface is defined on an inner periphery of the body. The beveled surface is configured and adapted to engage a wedge disposed on a roller wheel of a roll wheel assembly to hold the tire on the roller wheel. The invention also provides a method of securing a tire to a roller assembly in a pulverizer for crushing material. | 01-08-2009 |
20140099239 | Reduced sorbent utilization for circulating dry scrubbers - Circulating dry scrubbing (CDS) systems and methods utilizes a particle classification unit operation to separate unreacted sorbent (such as lime, limestone, or sodium-based sorbent) such that a reactive fraction of the cut stream may be selectively recovered to a flue gas scrubbing system. This reduces the amount of fresh sorbent that must be supplied for pollutant removal. | 04-10-2014 |
20150093295 | GAS DISTRIBUTORS FOR CIRCULATING FLUIDIZED BED REACTORS - A distributor for a circulating dry scrubber reactor includes a venturi section with a venturi section wall extending from a venturi section inlet to a venturi section outlet along a longitudinal axis, with the venturi section inlet connected to an inlet plenum and the venturi section outlet connected to a circulating dry scrubber reactor. A hub is mounted within the venturi section wall with an annular converging-diverging flow path defined between the venturi section wall and the hub for distribution of gas flow from the venturi section outlet into a circulating dry scrubber reactor space and for maintaining stable bed fluidization in a CDS system at a comparatively low system pressure loss. | 04-02-2015 |

20090232466 | COVER FOR OPTICAL FIBERS AND/OR OPTICAL DEVICES - Apparatus and methods are provided for controlling a light emission from an end of an optical fiber by utilizing a cover that blocks the light emission at the fiber end, a detector situated between the fiber end and the cover that detects the blocked emission, and a signaling device, such as an LED, associated with the detector that illuminates in response to the detection of the blocked emission. The apparatus and methods may further provide for the filtering out of light from the emission that is not used for communications. The apparatus and methods may also provide for the attenuation of the power of the emission before the emission reaches the detector. | 09-17-2009 |
20100162332 | METHODS AND APPARATUS FOR GENERATING LOCAL OSCILLATION SIGNALS - Generating oscillator signals with which selected signals may be mixed. Such oscillator signals may be generated by dividing a pilot tone, such as a 120 MHz pilot tone found on many cable TV systems. Oscillator signals for demodulating received selected signals may be similarly generated. | 06-24-2010 |

20090257747 | TESTING A FIBER LINK IN A COMMUNICATION SYSTEM WITHOUT INTERRUPTING SERVICE - There is provided a method for testing an optical fiber link. The method includes employing a wavelength division multiplexer (WDM) to receive a signal via a port of the WDM and multiplex the signal onto the optical fiber link. The signal is used in a test of the optical fiber link. There is also provided an arrangement of components for testing the fiber link. | 10-15-2009 |
20110135298 | OPTICAL SIGNAL SHUTOFF MECHANISM AND ASSOCIATED SYSTEM - A mechanism for adjusting or shutting off an optical signal within a network system is provided. The system may include a generating element for providing an optical signal and a bi-directional coupler for transmitting the optical signal to downstream components and fiber links and for transmitting a reflected optical signal based on the reflection characteristics of the downstream components to a converter element. The converter element converts the reflected optical signal to an electrical trigger signal that is used by a processing element to monitor the degradation or operational conditions within the network system. Based on the electrical trigger signal the processing element may adjust or shut off the optical signal at the generating element or at another element within the network system or another network system. The processing element may also send a communication signal to other elements or an operator to indicate unacceptable noise within the network system. | 06-09-2011 |

20130130519 | COUPLING MECHANISM FOR A PCB MOUNTED MICROWAVE RE-ENTRANT RESONANT CAVITY - The microwave signals are coupled from a transmission line embedded in a Printed Circuit Board PCB to a resonant cavity mounted on an external metalized surface of this PCB. The coupling mechanism implements an easy-to-fabricate mechanism leading to high-quality filtering owing to the fact that the end of the transmission line is provided with a metalized feeding pad located at the external layer of the PCB inside the resonant cavity. The resonant cavity is provided with a re-entrant inner stub orthogonal to the PCB and separated from the PCB by a capacitive gap. The metalized feeding pad is facing the inner stub in the area of the capacitive gap and is offset from the axial direction of this inner stub. The metalized feeding pad is further separated from the external metalized surface of the PCB by a surface capacitive gap. | 05-23-2013 |
