ABSTRACT: The shear deformations corresponding to the ultimate stress

Pr - Pr at which the deformation corresponding with the
ultimat stress limit, F_r, reaches its highest valueF, rm (by
the increase of the velocity of deformation) increases in
proportion to the concentration of the system and is a linear
function of the number of local bindings between the separate
chains. The depenedence of the value oft rm on the concentration
C corresponds to a hyperbola of the first degre.eit-~ The deformation
energy to be applied up to breaking quickly increases at low
concentrations of the gel; in the case of higher concentrations
c--.j 6 - 8% it practically tends towards a constant value. This
constancy indicates that the increase in bindings in the net
of the lattice is compensated by a decrease of the deformation
which corresponds with the ultimate stress limit. There are

ABSTR&CT: It was found (reference 1) that the fatty acid crystals are
capable of sorbing cations from aqueous salt-solutions and
are on this occasion converted to corresponding metal soaps.
The velocity of the exchange reaction is highly dependent on
temperature. This is especially connected with polymorphous
transformations of these crystals and with the hydration acting
upon the crystals. The metal cations especially strongly
penetrate into the lattice near the melting point of the
acid. The present paper studies the separation of hydrogen-
ions by crystals of lauric-, myristic-, palmitic- and
stearic acid in aqueous solutions of CuSO of various
concentrations. Figure 1 shows the dependince curvesTr'

of the PH .of the solutions (table 1) for the C 16_'C14_ and
C~2 -acids at various moments, up to 200 days.
T e curves of the acids pass a maximum at PH - 4,75, which
corresponds to C - 0,05 and to a quantity of hydrochloric
acid like 10:1. The poaition of the maximum is for the 3 last-
mentioned acids practically independent from the length of
chain of the acid homologue and is determined by the nature
of the electrolyte
[AgNO 3' Th(NO 3)4' Ce(NO3 )31
With a shortening of the chain of the acid homologue the
height of the curve increases, i.e. the H+-ions are separated
more intensively. The above-mentioned maximum represents an
anomaly which may be explained in the following manner: In
tests with palmitic acid in AgNO 3- solutions according to the
conductometric method the author found that the conductivity
Card 2/4 of this solution at first solution at first decreases, then

passes a minimum and again increases, in order to surpass
the initial value (figure 2). This Is to be traced back
to the initial decrease in the total concentration of the
electrolyte, apparently due to the molecular sorption of
AgNO 3. This sorption should thorofore be taken into account
in tests with fatty acid crystals. This sorption must
increase with increasing concentration of the electrolyte.
The deceleration of the separation of H+-ions with increasing
CuSO 4-concentration may therefore be in connection with the
influence of the same sorption. The inhibitions of the separat-
ion of H+-ions are less distinct in the shortest acid homologues.
Therefore the higher activity of the acid and the mobility
of its molecules in th( crystals, i.e. the "loosening" of the
lattice, reduces the effect of the inhibiting barriers.
This assumption was confirmed by additional tests. With an
increase in the weighed quantity of acid the anormal curve
with a maximum is transformed into a normal, uninterruptedly
ascending curve. In this connection the pY, drops to much
lower values (tabke 2, figure 3). Thereby the specific
Card 3/4 influence of the passivator decreases. Due to a larger

surface of the sorbent the reaction within a short period
of time only takes place in the surface layers without
penetrating into the interior of the crystal. Therefare the
"barring" influence of the adsorbed ions hadrly takes any
effect. The penetration of the electrolyte into the lattice
of the acid apparently begins at the more damaged parts of
the crystal, i.e. at the corners and edges where the acid
molecules are less completely packed and the polar groups
are better accessible for tha molecules of the electrolyte.
The supposed staFes of this process are described. The
polymorphous transformation accelerates the exchange reactions.

ABSTRACT: The simultaneous investigatiom of the mechanical properties of me-

presents a new mBthod for the study of the properties and of the com-
position of two-sided f ilzo,, The present paper employs the method of
shaar strength of surface layers and of two-aided films. Twoconcens
tric rings consisting of platinum wire with a diameter of 0,1 cm, and
with the radii R. - 2,738 cm and R2 - 2P995 cmi were mounted in a ho-
rizontal, position. The further set-upof the experimental arrangement,
is described. The authors investigated various saponines, which: obvi-
ouslq display widely differing abilities for th4~formatiom of films
and of foam and different mechanical properties. Here, imported and
Sovietic saponines were examined. The present paper inve5tigates the
data of one of the imported saponines, that is to say Kahlbaum. (Kalt-

the flowing process. The quantity P r of the surface layers increases
continuously with an increasing concentration, the quantity Pr of the
films produced from the same solutions passes through a sharp maximum
in the range of comparatively law concentrations of the solution. The
strength of the adsorption layer of the film reaches only half the
amount of the strength of the surface. Without doubt,, even saponines

ABSTRACT: The author has shown (Ref.1) that a large number of gel-

cent) limiting deformations. A system consisting of iwo
coaxial cylinders is described which can be used to measure
such deformations at different rates of deformation and pre-
set values of the deformation. The instrLuuent (illustrated
in Fig.1) incorporates the following features. The outer
cylinder can rotate at constant speed and is automatically
brought to rest at a preset angle. The instrument measures
the maximum shear stress wiiich develops when deformation up
to the preset angle takes place. The inner cylinder may be
kept practically in the initial position while the outer
cylinder rotates up to tiie preset angle. The inner cylin-
der is automatically released a short time after the

ABSTRACT: The authors developed a precipitation method for the pre-
paration of aluminum-ooapa in which aqueous solutions of
Al (so ) and sodium soaps are poured together, the pH being
heid Anhant. The general view of the laboratory equipment
used in the precipitation of aluminum soaps of naphthenic acids
is shown in fig. 1. It was established by experiment that the
thickening properties of the soaps and the structure and sta-
bility of their oleogels are strongly affected by the following
factors:
1. The ratio of free to bound alkali (fig. 2 and 3). The vis-
cosity of the oleogels of Al-soaps grows with their free alkali
content, attaining a maximum at 75-100o. The stability decrea-
ses when the alkali content increases. The most stable oleogels
are those precipitated with a free alkali content below 50%o.

the oleogels precipitated at different PH values (10-3-5)
grows with diminishing PH passing through a maximum at PH 5.
3. Temperature. The thickening capacity of the Al-soaps
increases with the temperature (20-920C) passing through a
maximum at about 800C. Thermal treatment of the prepared soaps
also raises their thickening capacity (fig. 8). The precipi-
tation and treatment temperatures have no significant effect
on the stability of the oleogels. "
Diminishing the concentrations of the Al 2(50 ) solutions
and particularly of the sodium soaps used for p~ehpitating
the Al-soaps raises the thickening capacity. A comparison of
the thickening properties of the Al-soaps prepared by the
"direct" precipitation method and by precipitation at constant
PH of the medium showed that on precipitating under optimal
conditions (PH 5, elevated temperatures) soaps with higher
thickening capacity are obtained by the latter method. The
dependence of the viscosity on the time of keeping the oleogels

ABSTRACT.- The composition and the thickening properties of aluminum
soaps are determined by the molecular weight and the natu-
ral organic radical of the acid, and by the ingredients
and preparing conditions of the acid. Among these factors,
the ratio of free to bound alkali plays an important role.
In this article, the p-eparation of aluminum soaps from
naphthenic acids with a molecular weight of 250 is des-
cribed. The temperature was 60 0C. The free alkali con-
tent varied from 25 to 200 %. Figure 1 shows that the best
results were obtained with an excess of 75 % of free alkali.

developed a method of automatic recording. The device
for this recording operates as follows: On the axis of
a cylinder a small mirror is fastened$ on which a beam of
light with rectangular cross section is incident through
a condenser and a focusing lens. This beam of light is
reflected by the mirror onto a selen-photoelement, the
illuminated surface of which is limited by a special

of the angle of rotation y of the interior cylinder of the

of the angle of rot tion e of the exterior cylinder, i.e.

initiation of the process. Subsequently the curves

side of less molecular interaction between additive and

ABSTRACTs In the introduction to the present paper the increasing
importance of consistent lithium lubricants is pointed out
and it is shown that their properties depend on the nature of
cooling. In the first part of the paper the material and the
methods of the investigation are described and the dependence
of the solid state of a 10 % isotropic solution of stearate
of lithium In medical vaseline on the nature of the two-stage
cooling is shown in a diagram (Fig 1). The curve has marked
maxima and minima. As shown by electron-optical investigation,
also the shape and size of the fiber-structure of the
Card 1/2 solution is connected with this phenomenon. Figure 3 gives

ABSTRACT: An apparatus is described which operates on the principle of
the tangent shift of a steel lamella, which has already been
used in asphalt investigations (Ref 1), etc (Refs 2-4). One of
the advantages of the apparatus is that the striicture of the
system to be investigated is not destroyed when the correspond-
ing substance is filled in. The apparatus (Fig 1, Draft) has a
ouvette and a drive. The latt.~_r.can load the measuring metal
lamella either constantly or _-',ncreasingly~in certain intervals.
The cuvette consists of t-wo 3cre-ired metal lamellas (Fig 2) of
stainless steel. The substaxc~~ to be investicated is filled in
a grooved indentation of th ~! cuvatte bottomNhere also the
equally grooved measuring metal lamella is inserted. The shift
