Title: Control of furnace cleaning for reflective ash using infrared imaging
Inventor: CARTER HUDSON R
IPC: F23M11/04
Filed: 1991-12-02
Abstract: A method and apparatus for monitoring reflective ash deposited on a furnace wall to be cleaned comprises an infrared video camera or other mechanism for taking an infrared image of the fur-nace wall. The image must include an area to be cleaned by the waterblowing as well as a surrounding uncleaned area. Photo detectors or other mechanisms are utilized to measure the image intensity at locations on the cleaned and uncleaned areas with a ratio between the intensities being taken. The cleaned area has low reflectivity and is dark compared to the uncleaned area which is white and has high image intensity. The image intensity ratio between the cleaned area and the uncleaned area thus rises from a low level immediately after waterblowing to a high level which approaches unity as the initially cleaned area becomes as unclean as the uncleaned area. This can be used as an indication when waterblowing must be manually initiated, or the ratio signal can be used directly to operate an automatic system to initiate waterblowing.

Patent CA-2065785-A1 (CA)
Title: Fiber optic cable monitoring system
Inventor: VOKEY DAVID E
IPC: G01M11/08
Filed: 1992-04-10
Abstract: ABSTRACT The invention provides a monitor for monitoring the condition of fibre optic communication cables. The system employs one or more of the optical fibres of a cable to monitor the cable structure for damage or kinks. By using two separate laser sources and simultaneously monitoring the optical losses at two distinct and separate wavelengths, the loss signature of the monitored fibre is determined, analyzed and related to the mechanical condition of the cable structure. To monitor splice points for moisture, a special optical splice sensor unit detects any penetration of water into the splice and transmits a coded alarm signal over the monitored fibre to the optical receiver. Every splice location is assigned a unique sensor code. The optical splice sensor is driven by moisture detection cell, which forms a single cell water activated battery. Water entering the monitored splice closure wets the tape, which activates the cell. The cell generates sufficient voltage and current to power timing, code generation and modulator circuits in the sensor unit for an extended period of time. The activated circuit drives a modulator which modulates the light travelling down the fibre. The modulated light is monitored at the equipment office and the address of the alarming sensor decoded.

Patent CA-2078740-A1 (CA)
Inventor: COLLES JOSEPH H
IPC: H04N5/12
Filed: 1992-09-21
Abstract: A system eliminates the adverse effects of serration and equalization pulses (periodically generated during the vertical sync interval) in regulating the frequency of horizontal sync pulses. These sync pulses provide timing information to regulate a video display. The system includes circuitry for stripping and processing the horizontal and vertical sync signals and the serration pulses from the video signals. These pulses are introduced to a first AND gate and through a first delay line to an input of a second AND gate.      Frequency divider output signals are introduced to the first AND gate and to a third AND gate through a second delay line having an equal delay with the first delay line. The output from the first AND gate passes to second inputs of the second and third AND gates. The second and third AND gates produce signals which represent the time difference between the sync and divider output signals and which have a maximum time difference equal to the delays of the delay lines. In doing so, the gates eliminate the effects of the serration and equalization pulses. A phase comparator compares the times of occurrence of the second and third AND gate signals and introduces to a low pass filter the signals representing the time difference. A voltage controlled oscillator produces a signal having a frequency dependent upon the magnitude of the output voltage from the filter. The frequency of the oscillator signals is passed to a frequency divider. The resultant divider signals are introduced to the first AND gate and the second delay line.

Title: Fixed and temperature tuned fiber fabry-perot filters
Inventor: MILLER CALVIN M
IPC: G02B6/34
Filed: 1992-11-30
Abstract: ABSTRACT OF THE DISCLOSURE    A fiber optic Fabry-Perot etalon filter constructed with a resonance cavity which is variable in length to enable variations in temperature to tune the filter to a desired frequency while maintaining accurate alignment of the fiber across the filter.  Each fiber end is encased in a ferrule with the two ends placed in a facing relationship.  The fibers are aligned and held by an appropriate fixture designed to allow a portion of the ferrule assembly containing the resonance cavity to expand or contract with temperature variation.  The two mirrors defining the nominal size of the resonance cavity may be deposited on the facing end of each of the two ferrules, on an end of a separate waveguide located between the ends of the  ferrules,  or  on  any  combination  of  these  elements.          Ferrules may be wafered, that is, a wafer of material may be bonded to the mirrored end of one or both ferrules.  A portion of the ferrule assembly including the facing ends of the two ferrule  assemblies  may  be  of  smaller  diameter  than  the remainder of the ferrules.   By altering the length of the reduced diameter portion, filters are fabricated with greater or lesser freedom of movement in adjusting cavity size, thereby enabling tunable filters of differing spectral ranges.  A fixed fiber optic Fabry-Perot filter is also disclosed utilizing ferrules, at least one of which is wafered and using one or more rotary mechanical splice fixtures to hold the ferrules in rigid alignment.
