there Is some change.in the molecular Interaction causing the retarding bond

decreases for elongations in the range 250-340%. The decrease is attributed to _&
decrease in the energy of the interchain bonds as a result of the straightening ofl

TITLE: Calculation of Permittivity of Dry and Humidified Rubber (K raschetu

PERIODICAL: Sb. nauch. tr. Yerevansk. politekhn. in-t (Collection of Scientific
Works of the Yerevan' Polytechnic Institute), 1956, Nr 12, pp 91-98
ABSTRACT: For the sake of simplicity, it is assumed that the permittivity of a
cured mixture is due to all components that are represented in large quantiti"
in the mixture. The equivalent permittivity for dry rubber is computed from a
scheme of a series (layer -by -layer) connection of two components, the rubber
proper and the filler A comparison of calculated and measured permittivity
revealed a good agreement for the rubbers (TS-30, TS-35, TS-45, TSShM-35)
examined in the work. Better mixing and seasoning conditions are conducive
to a more uniform distribution of fillers through the rubber mass and, conse-
quently, make the present calculation more reliable. Permittivity computation
for humidified rubber is made according to the stages of moisture absorption

Galculation of Permittivity of Dry and Humidified Rubber
It is assumed that, in the first stage of absorption. the moisture is placed in
parallel with the fundamental components of the rubber. During this period, a
deterioration of all electrical characteristics of the rubber is observed. The
formula for calculating equivalent permittivity corresponds to a scheme of a
moisture layer connected in parallel with a dry-rubber layer. This formula
holds true for an initial period of humidification (408 hours for TS-30, 72 hours
for TSShM- 35, etc . ) - Therefore, it is assumed that in the next stage of humidi -
fication, the moisture uniformly pervades the entire thickness of the rubber.
In this stage, the permittivity grows slowly. A formula is presented for calcu-
lating the permittivity in this stage. The third stage of the process is charac -
terized by cessation of moisture absorption. The permittivity no longer grows.
Formulas are presented for calculating the capacitance of moisturi zed -rubber
samples.

mechnaical properties of polychloroprene coatings are satisfactory and meet the
requirements of cable hose rubber as shown in Fable 2, The moisture absorption
of polychloroprene coatingsdepends on emulsifiers and stabilizers, Figure 2
shows the dpendence of the ausorbing capacity of L-3, L-4, and L-7 coatings and
also of L-7 Plus 10 % furnace carbon black coatings on the period of immersion at
d
to = 200C. Tests revealed a strong effect of polychloroprene on copper. HCI an
C12 separated from polychioroprene show the following reaction on copper: HC1+
Cu-.> CuC12+ H2 and C12-+ Cu -->CuC12. The resistance of these coatings to heat
oil, light and moisture can be Increased by addition of furnace carbon black
(Table 3) and MBM (MVM) vaseltne oil (Figs. I and 4) to the polychloroprene
mixture. The disadvantage of vasellne oil is that It facilitates the propagation
of micro-organisms; this Is countered by an addition of fungicides consisting
of a water emulsion of salicylanilide staDlIlzed by ammonium caseinate, TablA
4 gives the composition of L-7 latex mixtures. The coating process Is the fol-
lowing; the Item Is plaoed In a concentrated solution of 30 % CaC12 and then
Immersed in a latex bath. A negative feature of this method Is the eaturation
of the coating with saJts which Impair its electrophysical properties. Another

possibility is the "electric deposition" which is achieved by electrophoresis
and produces more resistant coatings (Fig. 5). The electrophysical properties
of coatings are Improved by syneresis which completely removes all stabilizers
and salts. Figures 6 and 7 show the results of tests in regard to dielectric
losses of polychloroprene latex coatings and volumetric electric resistances as
depending on the period of immersion. The use of latexes in cable production
produces airtight coatings of 0.3 mm or less, whereas type L-7 is considered
most suitab2e for thIs purpose Latexes mixed with fungicides and vaseline are
suitable for wires and cables used in the tropics. There are 6 figures, 4 tables

Abstract: It has been established by the work carried out
at the Institute of Apiculture that, during the
period of subsistence collections, no definite
difference has been observed between the egg-
laying capacity of the grey Armenian bees and that
of the yellow ones. During the period of general
collections, the queen bees ef the grey breed
restrict their egg laying, while in the yellow
