the exit of the smoke. The pipe is ordinarily
held in place by the teeth, not the lips, and the
smoke is drawn into the mouth well behind the
lips. The problem is caused by the combination of
factors noted above and is best corrected by a
disposable protector unit which is changed
periodically. Therefore, the evidence strongly
indicates that a continuous, at length, cooling,
condensing, absorbing, filtering, gas-releasing,
and air-diluting device can reduce detrimental
biological effects from tobacco smoking. The
effect on smokers of such a device would be (a)
air dilution of the toxic gases of tobacco (b)
cooling the particulate phase of tobacco smoke
(the Surgeon General's report cites many cases in
which cancer has not been produced using cooled
tobacco condensates) (c) adjustment of the heat
of the smoke to be further filtered by body
ciliary action once the toxins are no longer
vaporized and in full strength (d) exhalation of
toxins which have not been trapped in opened
pores, and (3) the combination of a fresh pipe
mouthpiece with cooled smoke as a means of
removing the irritation to the lips of pipe
smokers. Initial tests have shown that use of the
thermostatic filter may eliminate such symptoms
as cough and throat, tongue, lip soreness.
Logically, the elimination of such symptoms is
more difficult than preventing them to begin with
. It is anticipated that this proposed research
study will reveal that the thermostatic filter is
particularly effective in lowering the tendency
for new pathologies to develop in tobacco
smokers. Every effort will be made to review the
experience and claims made during the initial
test period and to determine through closely
controlled studies the relative merits and health
benefits of this filter technique. The
thermostatic filter is comprised of the protector
unit (1). Within the filter as shown is embodied
the filtering-absorbing tubular core (2) made of
balsa wood, which is best suited for this
function. To provide a constant circulation of
fresh air to mix with the smoke passing through
channel (3) and thus continuous sufficient
cooling, condensation and dilution, there are
four rows of five 1 mm. holes (5) along the stem
(4), which are spaced one-half inch apart. Each
row is staggered and spaced 90 degrees from the
next. Over the stem (4) of the protector unit (1)
is the tubular sleeve (6) with four rows of five
1 mm. holes (7) spaced one-half inch apart. Each
row is spaced 90 degrees from the adjacent row.
These holes are positioned so that when the
sleeve is revolved to a stop position, there will
be alignment with holes (5) for maximum fresh air
intake, exhaust and dilution. At 45 degrees from
holes (7) four other rows of five .80 mm. holes
(8) are provided so that the sleeve, when
revolved to the opposite stop position, will be
aligned with the holes (5), thus reducing the
opening to .80 mm. To fix the position to align
with the holes, a cutout (9) is provided on
sleeve (6). By turning the sleeve to the right to
stopper (10), which forms part of the protector
unit, the 1 mm. holes align to the left of the
smaller holes (8). A variation can be obtained by
revolving the sleeve slightly off of alignment.
The sleeve is necessary for more efficient
operation and serves to reduce the draft tot he
burning tobacco when smoking in windy areas, thus
preventing it from burning too rapidly and
increasing in heat content. The necessity for
decreasing air intake may be a factor when the
protector unit is new or the smoker has a weak
draw. The operating feature of the filter is
based on the principle that since smoke travels
fast, it must be processed at length. The maximum
length is shown in Figure 1 to which the
thermostatic principle can be applied without
causing difficulty in the draw or the smoker
experiencing a loss of flavor. Here the smoke is
processed for five inches, with 20 holes. A
minimum of eight 1 mm. holes over a two-inch
process is the least required for satisfactory
results. In the smoking process, fresh air is
incredibly admitted to the smoke channel. The
intake increases by virtue of the smoker's
sucking action. The smoke components liquify in
part. The gas phase, being volatile, in part
escapes through the openings--some is forced out
of the channel by the exhaling action of the
smoker himself the same holds true for the heat.
That which does not condense or escape becomes
diluted by the continually circulating fresh air.
Through this process, heat and chemical strengths
are reduced by as much as 80 per cent. Thus only
a cool, moderate-dosed smoke enters the mouth
which is not hot enough to cause the opening of
pores, allowing tobacco irritants to penetrate
them. While smoking, the condensed matter is
absorbed by the balsa core. Periodically,
replacement of the protector unit is necessary.
Lip cancer, in part, appears to be caused by a
stale mouthpiece as mentioned herein. The
protector unit (1) is expressly designed to
incorporate the mouthpiece (11) to avoid this
danger. Therefore, according to Dean Burk and
other researchers, smoking tests indicate that
cooled carcinogens do not penetrate the body to
produce cancer. The thermostatic filter provides
ample cooling and the nicotine is reduced in
strength. Heat which plays a significant role in
the pathologies related to smoking is sub
11292734 INTRODUCTION The Mankind Research
Foundation (MRF) is pleased to submit this
proposal for an experimental research program
designed to evaluate the potential effect of the
thermostatic filter on the health of smokers. It
is an established fact that the temperature of
smoke entering the body has a significant
biological effect on the smoker. Inasmuch as
smoking per se has not been significantly reduced
by health warnings, it is important to find means
of making smoking a less hazardous habit for the
smoker. MRF believes that the thermostatic filter
may provide such a means. Statistical methods
will be employed to analyze the results of the
use of the thermostatic filter on several
different control groups. It will then be
possible to determine whether or not the filter
should be recommended for public use with
commercially available tobacco products. It is
anticipated that the thermostatic filter may be
found, as a result of this research, to reduce
the health hazards of tobacco smoking, in a
manner comparable to earlier research, for
example, in the regular use of fluoride to reduce
the incidence of tooth decay, etc. The heat of
smoke plays a significant role in the pathologies
related to smoking. Tobacco burns at 1, 616
degrees Fahrenheit as air is drawn through it.
Whether it burns in a pipe bowl, cigar, or
cigarette, it produces a hot smoke which consists
of a heterogeneous mixture of toxic gases,
uncondensed vapor, and minute particulates.
Without a thermostatic filter, the smoke that
enters the mouth is hot from the beginning and
becomes hotter as the tobacco burns lower. The
internal areas of the body are already in the
upper 90's. The introduction of hot vapor causes
the pores to open in the cavities of the mouth,
the tracheobronchial tree, and the lungs. As a
result, the open pores more readily absorb the
harmful agents of the tobacco. These harmful
agents consist of a concentrated aerosol of
millions and perhaps billions of tiny particles
less than 2 microns in diameter. This aerosol is
formed of a vast number of compounds, 254 of
which have been isolated in the laboratory. At
least seven of them have been found to be
carcinogenic Benzo (a) pyrene, Dibenzo (a, i)
pyrene, Dibenzo (a, h) anthracene, Benzo (c)
phenanthrene, Dibenz (a, i) acradine, Dibenz (a,
h) acradine, the proposed design to be described
herein, are the old Arabian "hookahs", or
water-filtered pipes, and the recently advertised
"Aquafilter" cigarette holders. The latter, being
commercially available, provide the opportunity
for structuring a special statistical comparison
group as part of the suggested test program. (2)
The Surgeon General's Advisory Committee reported
that cigarette smoke and cigarette condensates
have failed to produce cancer when applied to the
oral cavity and pharynx of mice and rabbits or to
the palate of hamsters and that the oral mucosa
appears to be generally resistant to cancer
induction even when highly active carcinogens
such as Benzo (a) pyrene are applied. Some of the
difficulties in experimental design are
attributed to mechanical factors, such as the
secretion of saliva on the tissues of the oral
cavity and pharynx. Once again, as in the case of
chamber tests, there is no heat to open the pores
and assist the absorption of carcinogens into the
internal cells. The contention in view of the
fact that humans, who also produce saliva, appear
to be victimized by lesser amounts of irritants.
(3) Mouth and lip cancer tends to develop at the
location where a pipe, cigar, or cigarette is
habitually positioned. It is clear that the heat
of tobacco smoke entering the body is greatest at
the point of contact between the mouth and the
smoking implement. If the smoke alone were
responsible for the cancer, the damage should
logically be distributed equally among all areas
which the smoke penetrates. (4) Pipe smoking, in
particular, is causally related to lip cancer.
Mouthpieces of all present commercially marketed
pipes are permanent. These become stale and
impregnated with saliva, which contains a high
dosage of tobacco irritants, as evidenced by the
grey-tan-white appearance of a used mouthpiece.
This concentration of irritants, reacting with
the additional new irritants and hot smoke
filling the mouth with each draw, eventually
tends to produce lip cancer. It should be noted
that lip cancer is not necessarily a direct
result of the hot smoke, as the lips touch the
surface of the stem of the pipe which is never
hot some distance from the exit of the smoke. The
pipe is ordinarily held in place by the teeth,
not the lips, and the smoke is drawn into the
mouth well behind the lips. The problem is caused
by the combination of factors noted above and is
best corrected by a disposable protector unit
which is changed periodically. Therefore, the
evidence strongly indicates that a continuous, at
length, cooling, condensing, absorbing,
filtering, gas-releasing, and air-diluting device

Whether it burns in a pipe bowl, cigar, or
cigarette, it produces a hot smoke which consists
of a heterogeneous mixture of toxic gases,
uncondensed vapor, and minute particulates.
Without a thermostatic filter, the smoke that
enters the mouth is hot from the beginning and
becomes hotter as the tobacco burns lower. The
internal areas of the body are already in the
upper 90's. The introduction of hot vapor causes
the pores to open in the cavities of the mouth,
the tracheobronchial tree, and the lungs. As a
result, the open pores more readily absorb the
harmful agents of the tobacco. These harmful
agents consist of a concentrated aerosol of
millions and perhaps billions of tiny particles
less than 2 microns in diameter. This aerosol is
formed of a vast number of compounds, 254 of
which have been isolated in the laboratory. At
least seven of them have been found to be
carcinogenic Benzo (a) pyrene, Dibenzo (a, i)
pyrene, Dibenzo (a, h) anthracene, Benzo (c)
phenanthrene, Dibenz (a, i) acradine, Dibenz (a,
h) acradine, the proposed design to be described
herein, are the old Arabian "hookahs", or
water-filtered pipes, and the recently advertised
"Aquafilter" cigarette holders. The latter, being
commercially available, provide the opportunity
for structuring a special statistical comparison
