DR. S.R. EVELYN. llth January, 1973-
All PCL9 were made at Ajax by the Mark I PCL
process i.e.
three parts dryside materials to one part binder
and 7.5%
glycerol d.w.b. on product added. No physical data
on the
ma terials is available but there are important
differences.
PCL for B3.
It was requested that this be made by normal
Canadian
process in which drY5ide materials consisted of
.75% lamina
waste and 25% winnowings and the binder was made
from VSR
stem.
Thus, for the JANUS sample the dryside materials
consisted
of 75% lamina blend and 25% VS stem and the binder
was made
from VS stem.
(In Canada the stem was sieved over ill. Oversize
from
mixed grades classed as VS; oversize from sand
leaf grades
classed as VS-1 and undersize classed as VSR.)
The dryside materials were milled to 93.2% less
than
270 mesh.
PCL for B9. a3.
For this PCL the dryside consisted of~lamlna
Iblend. only
The binder was made from Canadian flue-cured stem

The lamina blend was milled to 78.4% less than 270

PCL for B10.
This PCL was made from three parts milled lamina
blend
and one part binder made from a new batch of
Canadian flue-
cured stem.
At the time this was made it was commented that
there
was difficulty in achieving a "coarse enough
flour" from the
lamina blend, 90% passing 270 mesh compared with a
normal 75%
in production. It was stated that the sheet was
denser than
normal production (It should be noted, however,
that the
fineness of the flour was similar to that for the
B3 PCL sample).

DR. S.R. EVELYN. Ilth January, 1973.
For previous PCL samples reasonable agreement
between
found and calculated chemical constituents was
obtained.
This was not the case for this sample and the
discrepancy
could not be accounted for :-
Calculated% Found %
Nicotine alkaloids 1.73 0.89
Total sugars 15.8 11.8
Reducing sugars 12.5 9.6
Ash 10.1 16.3
Water solubles 45.7 56.5
Calculated figures allow for 25% stem solubles in
the
binder - which is normal for Canadian PCL.
