Title: Pulp bleaching
Inventor: LEE ROBERT
IPC: D21C9/147

Granted: 1992-05-12
Abstract: "PULP BLEACHING"     ABSTRACT A method of reacting oxygen with a cellulose pulp slurry having a consistency from 8% to 16% to effect delignifi-cation or bleaching.  The slurry is dosed with oxygen incremen-tally by feeding a stream of it under pressure through a reaction path made up of a plurality of stages.  In each stage the stream is first confined to a cross-section at which it has a velocity such as to provide turbulent liquid flow and is then expanded to a cross-section at which it has a velocity such as to provide plug flow.  In each stage oxygen is introduced into the liquid flow under pressure in the form of a mass of minute bubbles to disperse them throughout so that the oxygen is brought into intimate contact to react with the pulp in the plug flow.  The treated slurry is recovered from the final stage.

Abstract: Abstract A method  and  arrangement  for  a  speech recognition system employs channel bank information to represent speech.  The method considers background noise included  with  the  speech.    The  method  includes determining three energy levels  for each channel,  the first  representative  of  background  noise,  the  second representative  of  the  input  frame  and  the  third representative  of  the  word  template  frame.    Values representing energy level differentials are assigned at each channel.   If the second energy level is less than the first energy level,  then a predetermined constant value  is assigned at that particular channel.   These values  are  combined  to  generate  a  distance  measure depicting the similarity between the two frames.

Title: Immunotherapy of tumor with monoclonal antibody against the 17-1a antigen
Inventor: SCHOEMAKER HUBERT J P
IPC: C07K16/00
Filed: 1987-07-07
Granted: 2001-08-07
Abstract: Gastrointestinal tumors are treated by administering to a patient afflicted with a gastroin-testinal tumor, a murine monoclonal antibody which specifically binds to an epitope of 17-1A antigen, the antibody being administered parenterally in multiple doses of 100 milligrams or more per dose for a total dose of about .1 - 5 grams of antibody.      The high dose murine antibody therapy is well tole-rated in patients. Further, the anti-murine anti-body response which generally develops in treated humans, surprisingly does not alter significantly the plasma half life of the murine antibody on repeat administration. Thus, high blood levels of antibody can be achieved with sequential injections of high doses to enhance transit of the antibody from intra-vascular space into the tumor bed and thus provide higher concentrations of the therapeutic antibody to the locus of action.

Abstract: ABSTRACT OF THE DISCLOSURE      A  method  for  accurately  assessing  and  rapidly modifying the phase and amplitude of the endogenous circadian pacemaker is disclosed.   A circadian cycle modification  capacity  assessment  method  comprises (before  and after a  stimulus)  eliminating activity-related confounding factors) associated with the sleep-rest  cycle which  otherwise  mask  the  state  of  the endogenous  circadian  pacemaker.    Based  on  either individual or normative assessment data, the circadian phase and amplitude modification method involves the application of  bright  (about  9,500  lux)  light  and, advantageously,  episodes  of  imposed  darkness,  at critically chosen phases to achieve rapid and stable changes in phase and amplitude.    The timing of the episodes  of  bright  light  may  be  chosen  either  by reference to empirically-derived phase response data, or by using a mathematical model in which the endogenous circadian pacemaker is a van der Pol oscillator.    A forcing function in the model  is substantially propor-tional to changes in the cube root of the surrounding illuminanco, in lux.  The amplitude of the endogenous circadian pacemaker may actually be reduced to substan-tially  zero,  so  as  to  bring  about  dramatic  phase modifications in diminishingly small periods of time. The methods find special utility in treating "jet lag" sufferers,  shift  workers,  advanced  circadian  phase experienced by many elderly subjects, and those afflic-ted with delayed sleep phase insomnia.
