1980s IPC research efforts cover a wide range of areas, including
MAPPS (Modular Analysis of Pulp and Paper Systems) development,
conifer cloning, corrosion control, impulse drying, strength
property measurement using ultrasound, PCB analysis, fast-growing
hybrid aspen, black liquor combustion research, and scanning
electron microscopy.
Microsphere retention systems improved consistency, formation,
and productivity due to increased drainage.
Gunnar Nicholson, a TAPPI Gold Medal winner and a notable
industrialist, donated $1 million to the Institute to establish
a fund encouraging student and faculty exchanges with corresponding
institutions in Sweden.
Precipitated CaCO3 made alkaline papermaking possible in areas
where lime could not be obtained from the ground. This resulted
in a net 2-3 point increase in the brightness of finished grade
paper.
Extended nip processing developed during the mid-1980s improved
production and quality and made it possible to have lower headbox
consistency.
Forest product research in growing eucalyptus trees and research
in pulping technology contributed to new strains and grades
of hardwood pulp suitable for a wide variety of end use products.
Eucalyptus pulps were used to provide increased capacity for
papermaking grades, increased softness in tissue and towel
grades, and because they offered a new unique combination of
strength and flexibility.
Environmental pressures to reduce the amount of bleaching
chemicals used led to the development of several processes
for extended delignification. These processes reduced the kappa
numbers by 50%. Pulps made by extended delignification were
then bleached cost-effectively with a variety of bleaching
agents and sequences.
IPC in cooperation with the U.S. Department of Energy and
the American Paper Institute conducted a full-scale plant trial
of the cold corrugating process at a Union Camp box plant in
Savannah, Georgia. Commercially available equipment was purchased
and installed with minor modifications.
Drs. Mann, G. Baum, and C. Habeger of IPC published research
on the determination of all nine orthrotropic elastic constants
for machine-made paper.
A Canadian patent was assigned to D. Johnson and M.D. Nicholson
for their research on solvent systems for polysaccharides.
A Japanese patent was assigned to Shu-Tang Han for his research
on fibrous material and its treatment.
A U.S. patent was assigned to G.A. Baum and C.C. Habeger for
their research on the on?line ultrasonic velocity gauge.
IPC assisted in the development of a rubber platen caliper
gauge to measure paper thickness. IPC conducted research
on ultrasonic measurements in the thickness direction of
paper.
A Canadian patent was issued to G.A. Baum and C.C. Habeger
for their research on the on?line ultrasonic velocity gauge.
IPC was awarded a research contract by the U.S. Department
of Energy to study high intensity drying technologies that
led to the development of impulse drying.
Laboratories were able, for the first time, to analyze dioxins
in parts per trillion. At this point, ultraminute quantities
of dioxin were discovered in some paper samples. Substantial
effort and research by industry was expended to identify
the sources and the various products and effluents that contained
dioxin. Within three years, many millions of dollars had
been spent, and solutions were available to minimize the
presence of dioxin in paper manufacturing.
Richard A. Matula was named fifth president of IPC.
IPC research on ultrasonic polar measurements of specific
stiffness identified variations in polar angle across the paper
machine and helped describe how transverse jet flows affect
paper properties.
IPC was awarded a research contract by the U.S. Department
of Energy to develop on-machine sensors to measure paper
and its mechanical properties.
A U.S. patent was assigned to D.T. Clay and T.B. Cartwright
for their research on the method for drying pulping liquor
to a burnable solid.
IPC's Board of Trustees reaffirmed the historical three-fold
mission and approved a plan to create an alliance with the
Georgia Institute of Technology and relocate the Institute
to Atlanta, Georgia.
An architectural firm was selected to design the Institute's
new facility on the Georgia Tech campus.
IPC Board of Trustees decided to relocate the Institute operations
to temporary quarters in Atlanta during the summer of
A U.S. patent was assigned to C.C. Habeger and G.A. Baum for
their research on the ultrasonic transducer.
IPC was awarded a research contract by the U.S. Department
of Energy to study black liquor delivery systems and nozzle
spray design for improved recovery boiler performance.
IPC modified its laboratory single-facer to determine the strength
of the green (uncured) adhesive bond at the time it exited
the pressure roll nip.
Institute received certificate of authorization from the Georgia
Department of Education to operate in Georgia. Facilities
on the comer of 14th and Hemphill Streets were leased by
IPC from the Georgia Tech Foundation. The building was completely
refurbished and occupied in July as the temporary quarters
for the total operations and the permanent facility for industrial
research.
Institute amended and restated its Articles of Incorporation
and Bylaws, effective July 1, 1989.
The total IPC graduates reached 1302.
A U.S. patent was assigned to G.A. Baum and C.C. Habeger for
their research on the method and apparatus for measuring
fiber orientation anisotropy.
The Institute's accreditation was transferred from the North
Central Association of Colleges and Schools to the Southern
Association of Colleges and Schools.
The Institute of Paper Chemistry was renamed the Institute
of Paper Science and Technology. A new logo helped to establish
the Institute's new name and preserve the familiar woodcut
drawing from the traditional logo.
The IPST first employees arrived in Atlanta to unpack and open
the Institute for business. The temporary facility was named
the IPST Industrial Research Facility.
IPST and Georgia Tech established a formal alliance agreement.
IPST students attended their first full day of classes in Atlanta.
IPST received a $15 million bequest from the estate of Florence
Thomson Kress to endow the Otto Kress Scholarship Fund.
IPST became a member of the University Center in Georgia, a
consortium of 18 public and private educational institutions
in Atlanta and Athens, Georgia.
IPST received notification of a $1.65 million challenge grant
from The Robert W. Woodruff Foundation toward the purchase
of the Industrial Research Facility.
IPST membership included 35 supporting members, 21 associate
members, and five subscribing organizations.
