Control have been completed &ad a report
issued.
AEY/JXM. (2) A photo-electric system has been
shown to give a aignal the value of
which is related to the amount of ecretage return.
The way in which this
signal should be compared with the variation of
individual cigarette weights
is being considered.
ku/ZKM. (4) The combination of a differential
transformer height measuring unit and
a U.V. recorder give a good trace of ecreteur
knife movement. A pressure
tranaduaer and meter unit, which will give a
similar comparable trace of the
pressure in the pressure call, are to be purchased
and fittad.

PROXECT 4300 PACKAGIRG STUDI M, AND PRODUCT
DEVELOP14EM
1,310 Studv of the Overwrap
NF/DEC. (4) The comparison of laboratory with
machine results is continuing.
DE3. (6) The evaluation of the influence of
external conditions on the flavour
transmission of polypropylens-based films in
continuing.
DEC/NF. (8) The work on tear-tape adhesion to
polypropylene-based film has been
completed. Two solvents have been obtained which
induce satisfactory bonding.
4320 Studv of Carton Materials
NIF. (4) The subJective assessment of H.L. packs
is continuing.

DEC. (4) The survey of materials for a flexible
pipe tobacco pouch is proceeding
satisfactorily. The work in covering water and gas
transmission and beat
sealing characteristics.
4340 Bondinx and Finiohes
NF. (1) No progress has been made an beat coated
H.L. blanks due to the full
time use of the packing machino under 4540(2).
NF. (2) The heat resistance of carton board
lacquer testing device is now being
assembled.
PROJECT 4400 FILTFR MANUFACTURE
FH/DM/~Gll. (3) Various methods of retaining water
in filters are betng examined.
These include the previously mentioned use of
additives to paper, such
as lithium chlorides together with the use of
various types of capsule
and sachet.
FH/DEC. (4) Preliminary trials on the manufacture
of granular filters of low
density materials have been completed.
FH/PGC. (5) Low density gramilar filters have been
made from milled righ'polyurethane
foam but with tri-aodium orthophosphate as a
bonding agent. The BONDEX
machine has been used with an experimental feed
system. The filters have
been made with different concentrations and
partials sizes of tri-sodium
orthophosphate and different particle sizes of
milled foam and samples taken
for measurement of filtration efficiency.
It is also being found possible to manufacture
these filters at high
pressure drops using a conventional cigarette
machine garniture system
together with the above mentioned feeder.

a particular coating
weight recommended. Another sample of printed
tipping more likely, to be
acceptable by B.A.T. is expected from Stzuel Jones
Ltd. soon.

compensated pneumatic/hydraulia
weight control to a 1964 type Mk.8 to overcome the
difficulties experienced
with a cloth t7pe filter. The performance is being
evaluated.
JXM. (7) A compressor and filter combination is
being tested for Southampton
Branch to see if the oil content of the discharged
air is sufficient17
low to prevent the staining of cigarettes.
