Patent CA-2068165-A1 (CA)
Title: Treatment of chips with black liquor
Inventor: HENRICSON KAJ
IPC: D21C3/24
Filed: 1992-05-07
Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus provide for the production of low kappa number (e.g. below 20) kraft paper pulp, and a low viscosity black liquor which is easily transported to a recovery or disposal stage. Comminuted cellulosic fibrous material is steamed, passed to a treatment vessel, and then introduced into the top of a continuous digester.  Black liquor is withdrawn from the digester and heated about 20-40 degrees C above cooking temperature (e. g. to about 170 degrees C), and then introduced into contact with the material in the treatment vessel.  After the material is treated with the black liquor, it is withdrawn from the treatment vessel, and passed to the recovery or disposal stage.  White liquor may be introduced into the treatment vessel after black liquor withdrawal, after passing in heat exchange relationship with liquid recirculated from an impregnation vessel to a high pressure feeder. Alkali may be added to the black liquor withdrawn from the digester, prior to heating, and after heating it may be passed to a reaction vessel.

Patent CA-2073247-A1 (CA)
Title: Coronary tracking display
Inventor: WHITING JAMES S
IPC: A61M25/01
Filed: 1991-11-12
Abstract: A method of displaying details of a coronary artery lesion in a cineangiogram, by adjusting each frame of the cineangiogram so that the lesion is continually displayed at a fixed location on a display. The remaining cardiac anatomy appears to move, in background, past a stationary arterial segment, thus making the displayed arterial segment easier to identify and to examine by medical personnel. Cineangiographic image frames are digitized and processed by a processor (201) and the image frames are digitally shifted to place the arterial segment in substantially the same viewing location in each frame. Sequential image frames may be presented to the viewer as a stereoscopic pair, to produce pseudostereopsis. The arterial segment appears to the viewer in foreground, as if it was floating in front of the remaining cardiac anatomy. Image frames may be further processed to aid examination by medical personnel. The processor may make quantitative measurements of the cineangiogram and may display results of those measurements to aid review of the cineangiogram. Frames may be averaged to reduce quantum noise and to blur any structure noise; frames may be compared with prior cineangiograms to increase clarity or contrast. Coordinate adjustments for a cineangiogram may help guide therapeutic procedures, or may help enhance other imaging procedures such as fluoroscopy.

Abstract: A METHOD FOR REDUCTION OF CENTRAL NERVOUS SYSTEM (CNS) EDEMA RESULTING    FROM HEAD AND SPINAL CORD TRAUMA                       ABSTRACT A method for reducing the rise in intracranial pressure accompanying head trauma includes the steps of significantly reducing the mean trauma induced increase in blood brain barrier permeability by administering an effective dose of an analog of amino acids 4-9 of adrenocorticotropin hormone, thereby significantly reducing the peak rise in intracranial pressure which normally accompanies the trauma.
Patent CA-2078049-A1 (CA)
Inventor: KUROKAMI YUZO
IPC: H03H15/00
Filed: 1992-09-11
Abstract: In a decision-feedback equalizer for use in combination with a demodulator (13) to equalize a demodulated signal into an equalized signal through a transversal filter (15), the transversal filter filters the demodulated signal into a filtered signal in accordance with a plurality of controllable tap gains.          The filtered signal is processed into the equalized signal on the basis of the binary level of the filtered signal.  The controllable tap gains are produced dependent on the demodulated and the equalized signal and a plurality of parameters.  A delivering circuit (38) delivers limiting values as the parameters to the transversal filter when the demodulator is put in a synchronization state.  The delivering circuit delivers additional values as the parameters to the transversal filter when the demodulator is put out of the synchronization state.

Patent CA-2087073-A1 (CA)
Title: Differential polarization ladar
Inventor: ANDRESSEN C CLIFTON
IPC: G01S7/499
Filed: 1993-01-11
Abstract: The present invention provides a long range LADAR (Laser Detection and Ranging), that employs in combination a 1.32 micron, Q-switched, diode-pumped Nd:YLF laser whose output beam is linearly polarized.  A quarter-wave plate is positioned in front of the laser such that the laser's (e.g. vertical)polarized light is converted to right circular polarization.  Reflection from a specular surface returns left circular polarized light.  A second quarter-wave plate transforms the left circular polarized light to horizontally polarized light which is then propagated through a beam splitter to two Gallium Arsenide Avalanche Photo-Diode detectors.  This invention provides both substantial reduc-tion in eye injury potential and good transmission in the atmo-sphere while improving scattering performance.

Title: Method and device in a crawling operation of a press felt in a paper machine
Inventor: HIRSIMAEKI MARTTI
IPC: D21F3/00
Filed: 1993-02-22
Abstract: The invention relates to a method and device in the crawling operation of a press felt in a paper machine. The press felt is passed as a closed felt loop through a nip defined between a center roll and a press roll in a press section of the paper machine.  The felt is driven during the running operation of the paper machine by means of a nip drive between the center roll and the press roll of the press.  When the paper machine is not operating, and the nip between the center roll and the press roll in the paper machine is open, the felt is moved, so as to moisten the new felt, by means of the crawling drive by rotating the drive roll.  An axle of the drive roll is permanently connected to a drive rim.  During the crawling operation, a drive wheel of a hydraulic device is brought into engagement with the drive rim.          When the crawling drive of the felt is not in operation, the drive roll is switched to the free revolving position by shifting the drive wheel of the hydraulic device apart from the drive rim.          The drive wheel is operationally connected to the drive rim.

Abstract: RECEIVER FOR LOCAL CALLS            ABSTRACT OF THE DISCLOSURE      This receiver,  commonly referred  to as a pager,  is intended to receive radio broadcast message signals, compr-ising  call  signal  information  and  message  information. It comprises a receiver (3) intended to receive and demodul-ate  coded message  signals,  a  memory  (5)  for memorising said message information,  a coded message  signal decoder (4)  for selectively furnishing message information to the memory (5) and function control means (8) capable of furn-ishing control signals to the memory and of receiving there-from message information  stored  therein.  The memory  (5) comprises  internal  processing means  for  controlling  the reception of message information coming from said decoder (4).  Thus  the  selected  message  information  furnished by the decoder  (4) may be stored in the memory without the necessity of having control available from a micro-computer or  processor outside  such memory which  thus becomes,  in a  manner  of  speaking,  "intelligent".  In  particular  the receiver may be applied to pagers incorporated in wrist-watches.
