A tabulated analysis of 114 cases of eczema reveals a high incidence of viscerAl
pathology. Correlations were as follows- Eczema of stage I (early circumscribed
foci) shows a high level of association with cardio- and neurological affections and
with visceral inflammatory processes. Eczema of stage If (recurrent widespread
circumscribed foci) shows predominance of associated cardiovascular, visceral and
a number of miscellaneous affections. Eczema of stage fit (diffuse) shows a high
rate of concurrence of visceral diseases only. In stages I and 11 th( re was a mean
incidence of 1.5 and 1.2 pathologies respectively per eczematous patient. Thus,
intrinsic as well an extrinsic factors play a role In the causation of eczema.

TITLE: A New Book on Helicopter Flying (Novaya kniga, o pilotirovanii vertoleta)
PERIODICAL: Grazhdanskaya aviatsiya, 195T, Nr 12 P 30 (USSR)
ABSTRACT: The article is a review of the book by G. A. TInyakov, Helicopter
Piloting (Pilotirovaniye vertoleta), published by the Voyenizdat,
Moscow, 1957. The author welcomes the book as filling a gap in
aviation literature. The only existing publication an the subject,
a description of the Ki-4 helicopter issued by the Redizdat of the GVF,
is considered a "failure". The reviever comnends the book's compre-
hensiveness, but objects to the lack of basic theoretical considerations,
and to the inadequate treatment of the problems of stability and control.

ABSTPAtT; The how of a vi,-.ous'incompressible liquid in conical slits is analyzed
on the basis of Navier-Stokjs' and flow-contin"ty aquations. It is shown that the
flow rate is of parabolAc character at any slit section and is a function of the
conicity parameter K . nj n. where ho and h, are the Inlet or exit clearances.
The pressure varies 'accor gg to convex (contracting slit) or concave (expanding
slit) curves, with & straight dividing line between these at X - 0. The smaller
the inlet clearance'at constant slit conicity and the higher the conicity at
constant Wet clearance. the mom sigmif icant are the deviations from the dIv14I a

ABSTRAM This is a work based mainly on the
results of r.-.-,.;aces 1-4 as applied to the piston
control valves used in aircraft hydraulic systems,
consisting of a double ended piston and a cylinder
with ports as shown in Fig 1. The clearance between
the piston and the cylinder can be made extremely
small so that the leakage past the piston lands is
very small even at high pressures. On the other hand,
it may not be reduced to nothing as this would induce
high friction forces. Based on practical experience
it seems appropriate to allow abouc one micron for
each 2.5 mm of the piston diameter. Due to pressure
difference at the two ends of the valve, there is a
Card 1/6 flow of liquid from the region of the higher pressure
SOV/147-59-2-10/20
Investigation of the Hydraulic Lock Phenomena in Piston Valves
towards the region of the lower pressure. For
viscous flows in a narrow clearance the rate of
flow is given by Eq (1) whose solutions for the
three different types (1, 11 and III) of the clearance
an shown in Fig 2 are given by Eq (2), (3) and (4)
respectively. Fig 3 shows the axial pressure drop
along these clearances. For the parallel clearance
the pressure drop is linear, i.e. depends only on
the axial position of the given poiat. But for the
divergent and convergent clearances it is curvilinear
and depends not on the axial distance (x) but also
on the size of the inlet clearance (hl) and the
tapering ratio (m). Figures 4, 5, 6 and 7 show the
effect of these as follows: Figures 4 and 5 apply
to the divergent clearance and Figures 6 and 7 apply
to the convergent clearance, in the first diagram,
in each case, hl being constant and the tapering
increases, while in the second diagram the tapering
is constant but the initial clearance decreases.
Due to the asymmetrical distribution of pressure
Card 2/6 around the piston there appears a transverse force N
SOV/147-59-2-10/20
Investigation of the Hydraulic Lock Phenomena in Piston Valves
which displaces the piston further and further until
it eventually contacts the cylinder, thus evoking a
frictional force which opposes any axial movement of
the piston. As the coefficient of viscous friction
decreases with the thIcknesa of the oil film
(see Fig 8 and Ref 5) it is seen that the locking
force increases not only because the transverse force
on the piston increases with the pressure in the
cylinder but also because the coefficient of
friction increases: at first on account of a
decreased clearance gap (and hence decreased the oil
film) and then on account of the viscous friction
being transformed tnto semi-dry friction when the
piston is in contact with one side of the cylinder.
Fig 9 shows under what conditions a locking force can
be produced: I - the clearance is parallel, the
pressure distribution is axisymmetric and, therefore,
there is no transverse force on the piston;
II - unstable position of the piston with a sideways
Card 3/6 thrust on the piston tending to push it back into its
SOV/147-59-2-10/20

central position4 III - divergent clearance, piston
axis displaced to one side by an amount c due to
which the pressure distribution is asymmetrical and
a transverse locking force is directly proportional
to c; IV - Converging clearance; when piston is
displaced sidewards there will be a restoring
transverse force produced, which pushes the piston
back into its central position, i.e. the piston is in
a stable equilibrium when situated centrally in its
bore; V - local attachment of some foreign body also
produces a transverse locking force N. The magnitude
of the locking force for the case of divergent
clearance is found from Eq (6) by integration, the
solution being Eq (7) which is obtained on the
assumption that the flow is laminar, entirely in
the axial direction and the coefficient of friction
being constant. The last relation may be expressed
in a dimensionless form as given by Eq (8), by
dividing it by a force N Z p,2.Z,r, which is a
reference force, and by intro ucing the relative taper

normalised pressure. Fig 10 shows its dependence on
the taper ratio when e =-O. Experiments confirm
these theoretical formulae as shown in Fig 11 where
the effect of pressure on the locking force is given
for the p~.stons A and B shown in Fig 12.1 and the
table under the figure (for the piston of Fig 12.11
there is no locking force). A simple method to reduce
the unbalanced radial pressures on the piston is to
make small circumferential grooves in it (Fig 13 and
14). Experiments with one type of valve showed that
d single groove reduces friction force from 100 to 40%
and seven grooves give only as little as 2.7%. Since
grooves and tapering of the piston help to maintain
the piston in its central position, this means that
they reduce leakages as well, because leakage
increases directly proportional to the eccentricity
of the piston position In the cylinder. To reduce the
friction more radically, the piston may be made to
revolve or to oscillate about its axis. This increases

Eg for a 55 mm piston with a flow of 120 k./min of the
liquid under a pressure of 6 kg/cm2, the friction
force of an ordinary piston valve was found to be
5 kg. while the same valve with rotating cylinder
suffered only 70 gr frictional force. There are

ABSTRACT: The article is an extension of earlier work, published
in Nr 2, 1959 of this journal, and deals with the friction
forces between the Riston-Xalyea and their casings. the
influence of high pressure on the hydraulic lock as well
as the effect of the total fall of input pressure on the
friction force. The characteristics of systems with very
high working pressure differ from those of syztems with
low and medium pressures. As shown in the earlier paper,
the force required to move the piston-valve increasas
steadily with pressure but when the working pressure is
of the order of hundreds of atmospheres new factors
appear and influence the locking of the valve. Both-tikLe

and hence the clearance changes so that the geometry
and configuration of the system alters. Also the
viscosity of the fluid along the clearance at these
pressure gradients can no longer be considered as
constant. Fig I shows the axial and transverse section
of d hydraulic valve pair, the inner and outer radii of
the cylinder being r I and r2 respectively, while the
maximum radius of the valve is r and it tapers down
to (r - 0. The radial deformahon of the cylinder due
to prassure p is then given by Eq (1), where a is the
Poisson's ratio for the cylinder material. Similarly
the radius of the piston will decrease by an amount
given in Eq (2), rnA being the local value of the
piston radius. Hence the total increase of the clearance
is the sum of the two as given by Eq (3), in which k is
a constant which depends on the geometry of the system
and the properties of the materials used. Eq (3) does

resulting from the pressure change (gradient) along
the cylinder. Since the maximum pressure is at the
inlet p, and diminishes along the cylinder (to P2)
hence the clearance will change in a similar manner,
e.g. for the system as in Fig 1, when r 1 = rnii = 6 mm,
r2 = 12 mm, T = 0.002 mm, to = 10 Mm, C = 0.005 mm
material of the piston and cylinder b9ing thg same
(cast steel 12KhNZA) with E = 2.04-100 kg/cm- and
a = 0.28, then with exit pressure p 2 = I kg/cm 2 the
change in clearance for various pressures is as quoted
in the table on P 5, from which it can be seen that
very high pressures produce changes in the clearance
of the same order as their initial values or of the
order of the tapering. Thus in the case of a system
with initially increasing clearance (susceptible to
hydraulic locking) deformation produced by the pressure
will tend to reduce the tapering, so that the clearance
Card 3/8 will become uniform at first and then, at very high

pressures, the clearance will actually decrease; under
these conditions the valve will not get locked.
Experiments confirm this conclusion. In the example
considered above, the uniformlty of the clearance
gap was obtained at 300 kg/cm . In the case of small
inaccuracies of the shape the pistcn may become free
from locking forces even at relatively low pressures,
as shown in Fig 2, where the full line represents the
force (F, in g) required to move the piston from rest,
and the dotted line represents the electric resistance,
in ohms, of the clearance (the lubricant between the
two metals acts as a dielectric). The graph in Fig 2
is the result of experiments carried out on a system
as shown in Fig 3, where (1) is the manometer
registering the inlet pressure, (2) is the valve,

minute before the readings were taken. Each experiment
was repeated three times. The initial force needed
to move the piston with no pres aure was 44 g; it
increased to 21500 g at 75 kg/cm and then decreased until,
at 200 kg/cm , the piston was completely free from
locking, the force needed for the axial moveient becoming
again 44 g for all pressures up to 300 kg/cm . With no
inlet pressure into the lubricant the resistance of the
system oscillated between 0.5 to 3 ohms. As the pressure
increased the valve was pushed towards the wall on one
side squeezing out the lubricant from that side until
full contact was established so that resistance fell to
zero. This happened at pressure of about J5 kg/CM2 and
conditions remained static up to 150 kg/cm , after whic
the resistance began2to increase (2.8 ohms at 200 kg/cm
11 ohms at 250 kg/cm ) indicating that the contact between
the piston and the cylinder was broken and the valve

the causes of hydraulic jamming of valves may be the
insufficient elasticity of the housings. These, very
often, may have a variable outer form so that the
thickness of the wall is variable. When the initial
clearance is small, it is possible, therefore, that at
high pressure with deformed piston the magnitude of the
clearance in some places will increase while in the
other will decrease so that the piston becomes jammed
and no movement is possible at all. Experience shows
that the magnitude of the locking force depends on the
time during which the pressure acts on the system.
This may be explained by the accumulation in the
clearance of small foreign particles from the lubricant
and also by absorption of the charged ions by the
metallic surfaces. If the inlet pressure is then
suddenly reduced to zero, the conditions do not return
immediately to those of the initial state and the force
Card 6/8 needed to move the piston may be many times larger than

that which would have been required if the pressure
were not applied at all. In fact, several movements
of the pistons are required before the conditions
return to the initial state. The plot, Fig 4, shows
the effects of time and pressure on the magnitude of
the locking force F. The results were obtained
during the tests of a system shown in Fig I in which
the dimens ons were as follows4 piston dia. 12 mm,
piston w!G'h 10 mm, diametral clearance 10 microns,
outer diameter of the cylinder 50 mm- Both the piston
and cylinder were made of U12 carbon tool steel. The
surfaces were heat treated until their hardness reached
the value of R = 50 and then they were ground and
polished. Eachcexperiment was repeated three times
and the data were taken over the first minute after the
pressure was removed. The effect of impurities in the
lubricant on the locking force F is shown in Figs 6

by passing it through special paper filters supported

valve and the piston were washed with aviation gasoline

TEXT, Experiments with hydraulic. piston valves employed in
governing mechanisms etc show that if the hydraulic pressure is
large the frictional. forces against the motion of the valve inay
increase up to a hundred times the corresponding values under low
pressures (Refs' 1. 2), Such a large increase in resistance to
the movement of the valve may cause partial or total failure of
the system. In order to diminish the re5istance, it is usual to
make one element of the hydraulic pair either to oscillate with
high frequency and small amplitude or to rotate about 1.ts axi5.
The earlier work of the author T..M. Bashta shows that such a
rotational motion of the tube diminishes the force of resistance
from 5 kg to 70 grams. The present work was carried out in order

to evaluate the effect of the oscillatory motion of the piston on
the resistance to its motion. The range of oscillations tested
was from 0.1 to 2.4 mm, with the frequency of oscillations from
2 to 30 r_p_,;. Oscillations of the piston were produced by an
electromagnet which was connected axially with the piston and was
fed by d,c. of alternate polarity using a rotary switch. This was
driven by a variable cpeed (120 to 1800 r p.m.) motor giving
s,witching frequ3ncies of 2 to 30 per sec, The piston -.,alves
tested were of two-collar type with a single groove between the
collars; diameter of the collars 12 mm, width of tbe collars
10 mm. The shape of the valves was so chosen that under pressures
used, they seized. as described in earlier work of the authors
(same journal,. 1.959, No. 2). Experiments showed that the change
of amplitude of oscillation in the range from 0.1 to 2.4 mm at the
given pressures did not affect the magnitude of the seizing force,
but the higher the pressure of the fluid the higher the value of
the seizing force. As the frequency of oscillation increases, the

seizing force diminishes at first but then becomes sensibly
constant as shown in Fig-3. In order to determine the force
necessary to move the valve under various pressures when the
valve oscillated a series of experiments was carried out up tc
a pressure of 400 kg/cm2, The valve was kept under a given
pressure for a minute and then it was moved. Fig.4 shows the
results of these experiments for three different valves., a, 6
and C, . Ringed dots indicate the forces necessary to shift
the valve without oscillations, while solid dots indicate the
corresponding forces with the same valves when oscillating. it
is clearly seen that oscillations reduce the resistance to the
motion of the valve, Finally, some experiments were carried out
to find out the effect of a sudden drop of the pressure in the
system. Figs 5 and 6 show these results. The pressure was
built UP to 500 kg/cm2. kept at that value up to 20 minutes and
then suddenly reduced., As is seen from Fig-5. the forces
necessary to move the piston in those circumstances fall

substantially when the piston oscillates (ring dots) as compared
with those when it does not (solid dots). The explanation is
that when the piston is not oscillating the flow of the fluid
past it is greatly reduced with time at high pressures, while with
the piston oscillating the flow of the fluid is not impaired at
all, as shown in Fig 6.

TEXT; The possibility of using different types of plastic materials as
supporting connections between structural elements of madified and non-
modified wood and even of plastics was examined. It was established that
pine and bolts of different plastics can suitably be used owino to their
high supporting capacityq slight deformation, low weight, and simple
manufacture. It is stated that it is most expedient to use pine and
bolts pressed of plastics; this does, however, Dt exclude the use of
similar pine and bolts obtained by machining. Abstracter's notet Com-
