The gial c' th's work is the. redaction of product variabilit@_-- cc-n-

tneans of achia,-,Lng this control is to have;
(at on-rachine perforation
and on-rachine ventilation Monitoring
with (z) feed-back control from the monitor to the per-47rator.
The role assicne.1 to GRFMC has Leon the assessment, and d&-.--:!_'.)pment
whare appropriate, of the various oerforation and monlt2rinq te=@:niqties
p,.;t fcrward by the major machinery suppliers in order that su:7. tech-
nicues, when effective in their own right, may be brought tocether to
prov'(Ie cc.)ntrolled ventilation levels. The direct involvement :f GR&..')C
will cease when the tc=hniques have been validated sufficiently -'zr them
to be for long term trials in the factories and when prota-
tvoes ha-.-a been developed to the stage wfiere the nachinery
can pr-)ceed with the manufacture of production units. Thereaf@ir, the
.G7&:.IC role will' change to one of Assisting the transfer of on--@ach:.ne

factories.
initially, some two years ago, it was foreseen that thIs shoull become
a major worst area of the CR&DC programme for a few years only. 3v the
end of 1?53, -,;R would expect most of the work in th.Ls area =3 have
been concluded and resources reallocated. There are, there-4:re, no
su.'.,stantial revisions proposed to the progra=mt. however, '-@_M'.n the
rr@ar@.,ss -.5- ar.Ttier year, it is possible to se--- the remainder
of this progra-ra morn clearly.

With tha completion of our testing of the preproduction C106 and the
recor.iendatici that i@ s'-c,.:Id undergo full' production trials in a
factory, no furt."r invL'.ement Is recuired from GR&DC for the time
beinq. Progress with on-nac'n_,.no perfo ration is dependent on Molins,
who do not seem to be puttin; great effort into the project.
3. SASID Ventilation System
Development of both the electrostatic perforator and the ventilation
r3onitor is progressing jat43!actor_,Iy and this Ls likely to be the
first automated ventilation control svstem to be tested in GR&DC.
Exoerimcnts will continue sen-arately With the perforator and the
monitor during 1932 and fead-back control experiments can be expected,
to continue well 1983.
Future Allocation af Resources
As previously mentioned, the pro4cc@s in this -omrk area are relatively
short term. 11, is hoped that t.-.e-, w-JI'l core to fruition during the
next year with transfer intc the factories of the developed
technology. Therefore, it is to be excected that resources -nay be
transferred to other projects during the latter part of the coming
three years. Likely reciptent projects are described under Work Area
!3. For examnle, work an :.Ie manufacture of cigarettes with expanded
tobaccos can be conveniently undertaken during and between ventilation
project tasting and this is also thn case with investigations into the
objective and subjective az;c--ts of different methods of cigarette
ventilation.
