Title: Method for synthesizing a peptide containing a non-peptide bond
Inventor: COY DAVID H
IPC: C07K1/10
Filed: 1987-06-26
Granted: 1992-09-15
Abstract: Abstract This invention features a method for the solid phase synthesis of non-peptide bonds (CH2-NH) in polypeptide chains.  These polypeptides are synthesized by standard procedures and the non-peptide bond synthesized by reacting an amino aldehyde and an amino acid in the presence of NaCNBH3.         This invention also features somatostatin analogs with non-peptide bonds.         This invention further features a solid phase method of chemically modifying a peptide.  The method involves synthesizing .alpha.-N-R and side group N-R analogs of peptides, where R is an alkyl or aryl group, by reacting a carbonyl- containing compound and an amino acid in the presence of NaCNBH3.

Abstract: ABSTRACT      An apparatus for varying the pitch of propulsor blades of a gas turbine engine by eccentrically driven gears.   The  gas  turbine  engine  includes  a  rotating structure,  an annular  gas  flowpath  coaxial with  the rotating structure, a plurality of rotor blades coupled to the rotating structure and extending into the gas flowpath  such  that a gas  stream flowing through the flowpath causes the rotating structure to rotate with respect to the stationary member  and a plurality of variable pitch propulsor blades coupled to and disposed radially  outwardly  of  the  rotating  structure.    The pitch of the blade is varied by a pinion gear coaxially coupled to one of the propulsor blades and and interal gear  radially  disposed  about  the  pinion  gear  for driving the pinion gear.   Annular displacement of the pinion  gear  causes   angular   displacement  of   the propulsor blade with respect to the rotating structure.          The  internal gear  is revolved about the pinion gear whereby the pinion gear  is  angularly  displaced  with respect to the rotating structure.

Title: Granular inorganic moldings and a process for production thereof
Inventor: NAKAMURA SEISHIRO
IPC: A61F2/28
Filed: 1987-10-06
Granted: 1993-11-23
Abstract: Abstract According to  the present invention,  there  is provided granular inorganic moldings characterized in that when the ratio A/D  of  the  maximum  diameter  D  and  the  maximum  length  A perpendicular to the maximum diameter of the granular molding is 0.5 to 0.9 and in that at least 80% of the granular moldings have a shape such that the crossing point of A and D is within 0.3D from both sides of the center of D.   Such moldings can be obtained in a high yield by filling inorganic powders capable of calcination into an organic porous body having a 3-dimensional net-like structure and subjecting it to press forming thereby to form granules of the inorganic powders in pores of the porous body and then burning off the organic porous body and at the same time, calcining the granular molding.  The granular inorganic moldings are useful as bone fillers, etc.

Title: Method and apparatus for sorptively storing a multiconstituent gas
Inventor: TURKO JOHN W
IPC: F17C11/00
Filed: 1988-04-25
Granted: 1993-02-16
Abstract: ABSTRACT OF THE DISCLOSURE The disclosure relates to a  method and apparatus for  sorptively storing a  multiconstituent gas  in, and  for selectively  releasing  the multiconstituent gas from, a vessel having a  predetermined  sorbent material therein, while  substantially preserving  minimum quantities  or concentrations of certain constituents of the gas.  In such a method  and apparatus, a first of the constituents of the multiconstituent gas  which is preferentially  sorbed by  the  sorbent material,  is present  in  the multiconstituent gas  in  a  predetermined  minimum  concentration  level substantially less  than  that of  the  second constituent.   First,  the sorbent material in the vessel being sorptively saturated with a pre-storage quantity of  the first  constituent at  a first  predetermined  pressure. Then the multiconstituent gas to  be stored is introduced under  pressure into  the  vessel,  with  the  vessel,  being  pressurized  to  a   second predetermined pressure above the first predetermined pressure.  Thus both of the first and second constituents are sorptively stored in the  vessel on the sorbent material therein.  When the stored multiconstituent gas is selectively released from the  vessel, the sorbent material desorptively releases the  multiconstituent  gas  with  the  first  constituent  being present in at  least the above-mentioned  predetermined concentration  as the pressure in the vessel decreases.

Abstract: ABSTRACT      Ozone and chlorine are used to bleach cellulosic fibrous material pulp in the production of kraft pulp for paper and paper products, being applied together in a mixture.  When the ozone and chlorine are applied simultaneously it is possible to achieve delignification to a greater extent than is possible utilizing chlorine at any level.  The total chlorinated ring compounds in the bleach plant effluent are remarkably reduced utilizing the ozone-chlorine mixture, compared to all chlorine, with resulting decrease in the fish toxicity of the bleach plant effluent.  Utilizing an O3/Cl2 Eo D bleaching sequence (only three stages) it is possible to obtain pulp with 90 TAPPI Absolute, or greater, brightness.
