Patent CA-2069017-A1 (CA)
Inventor: JOSEPH JAMES C
IPC: D21C9/153
Filed: 1992-05-20
Abstract: A process for conditioning an ozone gas recycle stream in an ozone pulp bleaching process, wherein the level of carbon dioxide in the recycle stream is controlled to allow full capacity operation of the ozone generator. Carbon dioxide concentration is identified over the relevant operational ranges and maximum concentration is identified for full capacity/optimum efficiency operation.  Specific methods are described for controlling carbon dioxide concentration including purging a portion of the recycle stream, counter-current scrubbing of the recycle stream with an alkaline solution and passing the recycle stream through an adsorbent material. Contaminants entering the system also may be reduced by directing the purged recycle stream, which is relatively oxygen rich, into the dewatering press where pulp consistency is increased.  In this manner nitrogen surrounding the pulp is displaced by oxygen and thus, does not enter the bleaching/ozone system with the pulp.

Title: Method for evaluating similarity of signals having a carrier frequency offset
Inventor: INKOL ROBERT J
IPC: G01S7/02
Filed: 1993-01-05
Abstract: A method and apparatus for evaluating the similarity of multi-mode radar pulses detected by a passive ESM receiver. The method consists of fitting a straight line to the differential phase of pairs of received signals, one signal of a pair being a currently received signal pulse and the other a previously received signal pulse, by a best least squares fit method. The slope of that straight line gives the frequency offset between the signals and the mean square error between the actual phase-time data and the straight line indicates the similarity of the signals. A second measure of the similarity of the signals can be obtained by applying statistical tests for serial correlation in the difference between the phase-time data and the straight line.

Patent CA-2088459-A1 (CA)
Inventor: WEDDING BERTHOLD
IPC: H04B10/2513
Filed: 1993-01-29
Abstract: When digital signals are transmitted over optical fibers (3), which have a considerable chromatic dispersion at the wavelength being used, the length of the transmission path is very limited when the digital signal to be transmitted is converted into an optical signal by means of intensity modulation. If frequency modulation (also called FSK = Frequency Shift Keying) is used instead of the intensity modulation, the bridgeable path can be greatly increased, but requires a suitable optical receiver at the receiving end. The invention utilizes a simple optical receiver (4), which is not sensitive to frequency modulation, but to intensity modulation. This is possible, because an intensity variation is created, due to the chromatic dispersion of the optical fiber (3) and the resulting running time differences of signal portions at different wavelengths (.lambda.0, .lambda.1) from the initial frequency modulation during the transmission over the optical fiber (3), which process is contained in the digital signal.

Title: Recoilless projectile launcher
Inventor: CLARK ROBERT O
IPC: F41A1/08
Filed: 1992-03-03
Abstract: A projectile launcher and in particular a mass/countermass projectile launcher in which the piston intercepts) comprises a braking collar (8) made of a material which exhibits constrained progressive crushing. When a projectile (18) is fired the launching piston (10) impacts upon the braking collar (8) at the muzzle of the launcher and initiates constrained progressive crushing in the collar (8). The crushing of the collar (8) absorbs the kinetic energy of the piston (10) thus arresting the axial motion of the piston (10). The projectile launcher according to the present invention can be less massive than similar launchers that use conventional metal piston intercepts which is an advantage if the launcher is designed to be shoulder-launched by a human operator. The type of collar material preferably used is made of a solid filler embedded in a plastics matrix and in particular the solid filler is made of reinforcing fibres.
