The central water supply installation of a town was studied. The purification station
of the installation treated river water of a low 'hardness' by means of coagulation
with aluminiurn sulphate. The resulting drinking water was transported to the town
through a 14 :,m. pipeline. The quality of the water on leaving the purification
station was acceptable, but at the end of the pipeline it was turbid and yellowish and
had an unpleasant taste. The deterioration of organoleptic properties was due to
corrosion within the pipeline, evidence of which are the negative value of the
stability index. the high concentration of divalent carbonic acid, and the increase
in iron concentration during transport.

T A method is Datented in which the local exchangeo or e.x-ch.an-
.--e areas are described by direction numbers with a variable number
of digits. T'he outgoing register fixes the ahole-dialled nu,..'Iber and
sends to the transit register a group of digits only equal to the
number of dir-its of the longest number -found in the given system of
numeration. Fo.- shorter direction numbers the missinr numaber of
digits is supplemented by the initial digits of the subscribe.-Is
c-
numbt?r. The digit group so obtained is sent successively by cn-,ren-
-ers to -'-he last transit re-
tional means between the transit re-ist U
Gister which selects from the received group only the digits of
the subscriber's number contained there and sends them to the local

assumed in the form
P - RT,

In A C T
where p is the pressure, V the volume, T the temperature, and r V1/3. R is the
gas content, A, C, and rm are characteristic constants of the strongly compressed
gas or liquid. The article supplies the values of these constants for nitrogen,
amnmonia, and water. The equation can be used to determine a number of.thermo-
dynamic quantities; in particular, the heat capacities cp and evs the adiabatic

by the common relation

Formulas are given for cps cvj and Us and these quantities are calcula-L'ted numeri-
cally for nitrogen as functions of p for T = 50 and 1000C. It is noted that,
unlike what happens in ideal and weakly compressed real gases, the velocity of
sound drops with temperature increase in a strorZly compressed gas under conditicrs
of constant-pressure.

The theory of,the Brown'motion in the critical range
PERIODICAL: Doklady Akademii nauk SSSR,' v. 136, no. 6, 1961, 136.8-1371
TEXT: Proceeding from earlier papers (Refs. 1-3), the authors study the.,
vanishing of the Brown motion in,the critical range when a mixture is
senarated into two layers. For the mean square displacement of the
particle, they write down: ST - 2Dt (1). As D is a diffusion
coefficient, it must vanish in the critical range as was experimentally
proved in Ref. 4 on iodine dissolved in C02. The present paper interprets
this standstill of the particle. The authors prorceed fr' OM
Smolukhovskiy's equation:
(t., R.; t + r, ca (t., )q.; t7) w (t, r; t + -r, R) dr, (2)1
where Lj is the Drobability density for that the particle passes over from

placement of a particle along a straight line in the form of a series of

It is assumed that N steps of the second type correspond to a distance L.1
