Patent CA-2025522-A1 (CA)
Title: Explosion pulping
Inventor: HORNSEY DEREK
IPC: D21C7/00
Filed: 1990-09-17
Abstract: ABSTRACT           In an explosion pulping process an inert gas  is  injected  into  the  steamed  pulp  prior  to explosion,   to  raise  the  pressure;   the  resulting exploded pulp displays improved mechanical properties and requires less refining time and refining energy.          By  employing  lime  in  a  presoaking  treatment  and carbon dioxide in the inert gas,  deposits of calcium carbonate  are  formed  on  the  fibres,   providing improved brightness characteristics.

Filed: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE            A method is disclosed for producing hybridoma cell lines by fusion of immunized splenocytes of the mouse with mouse myeloma cells.  The splenocytes are immunized against interleukin-6 prior to the fusion.  Three different cell ines can be identified and isolated from the fused cells, that is the hybridoma cell line with the C.N.C.M. deposition number I/913 (BE-8), the hybridoma cell line with the C.N.C.M. depositon number I/911 (BE-4) and the hybridoma cell line with the C.N.C.M. deposition number I/912 (BF-6), which produce monoclonal antibodies which recognize human interleukin-6 and which in dependence upon the different cell lines each bind themselves to a different epitope on the interleukin-6 molecule.

Title: Interference fixation screw with integral instrumentation
Inventor: MAHONY THOMAS H III
IPC: A61F2/08
Filed: 1991-02-04
Abstract: Express mail No. 311460550W               ABSTRACT OF THE DISCLOSURE A  fixation  screw for  securing  a  bone graft  of  a tendon section in place in a ligament tunnel is formed from a biocompatible plastic or bioabsorbable material. The tendon section is used to replace a ligament and has a tendon section attached at each end to bone grafts. The fixation screw is tightened between the bone graft and bone surrounding the ligament tunnel to secure the bone  graft  in  place  by  forcing  it  against  the bone surrounding the ligament tunnel.   The material is soft compared to bone so that threads of the fixation screw do not cut into the bone graft or bone surrounding the ligament  tunnel when  the fixation screw is tightened. The   fixation   screw   is   formed   to   have  integral instrumentation.  A body is molded or fabricated as one piece from the material and has a threaded end, formed as  an  interference  screw,  and  a  relatively  thicker handle  portion  connected  to  each  other.   The  handle portion forms the integral instrumentation in that it is grasped to turn the fixation screw to tighten it.  The threaded end is inserted between the bone graft and bone surrounding the ligament tunnel.   The handle is turned to tighten the threaded end between the bone graft and surrounding  bone.   After  the  fixation  screw  has  been tightened,  the  portion  of  the  fixation  screw  which extends  beyond  the  surface of  the  bone  at  which  the ligament  tunnel  opens  is  trimmed  off,  leaving  all surfaces flush.

Title: Circuit for demodulating psk modulated signal by differential-detection
Inventor: SHIMAKATA YUKIHIRO
IPC: H04L27/00
Filed: 1991-03-22
Abstract: ABSTRACT OF THE DISCLOSURE    In a demodulator circuit which is simple in construction, a PSK modulated signal is  converted in frequency into a quasi-base band signal and is then  subjected to complex  separation.          Partly  since a  phase  angle  sampled from  a  digital complex signal  is supplied  to  a differential-detector  circuit,  and partly since the  differential-detector circuit  processes only the  phase  angle,  the  differential-detector  circuit  has  a simple construction.  As the detected  phase difference between two  successive symbol  data, an  error between  a carrier wave contained  in the  modulated  signal and  a locally  oscillated frequency on the  receiving side is compensated and is  output-ted as a digital demodulated signal.

Inventor: YUN YOUNG-HAN
IPC: H04L1/00
Filed: 1991-09-19
Abstract: A method for receiving and processing predetermined signals in paging receiver with a battery save function.          A  first  to  third  predetermined  codes  of  a  batch  are detected.    Then,   if  an  error  occurs  in  a  second predetermined  code  of  a  next  batch,  not  a  second predetermined code of the next batch is searched for but continuously the BCH-decoding is performed with code words in the next batch by the BCH decoding algorithm.  Thus, if a non-error code word is detected in the code words, the second  predetermined  code  in  which  an  error  occurs previously   is   recognized   as   the   normal   second predetermined code and a subsequent address code word is searched   for.    Accordingly,   even   if   the   second predetermined  code  is  missed,   at  the  normal  batch construction, the missed second predetermined code can be compensated by the subsequent code word.
