TITLE: An autoclave for setting cement at high temperatures and pressures
SOURCE: Bureniye, no. lo, 19660-26-28
TOPIC TAGS: cement, netrolVm engineering, test facility, pressure effect$ high tem-
perature *ff4wt
ABSTRACT: The authors describe alarge autoclave designed for studying the physical
and chemical properties of cement after setting under the conditions which exist in
deep gas and oil wells. A diagram of the autoclave exid'its hydraulic system is shown
in the figure. The unit-coneisto of casing 5 which is 1800 mm long with an outside di-
ameter of 178 mm and an inside.diameter of 90 mm. Plugs 3 with tapered threads are
F- screwed into both ends of the casing. Inside each plug is a rod 2 with support plates.
An, elastic sealing ring 4 'is, located. between the support plate and the face of the
plug. Tension on nut I cMpresses the seal sufficiently for holding the starting pres--
sure. As the pressure increases. the plate compresses.the-ring further to provide re-
liable sealing. A thermaeter bulb T and wncmeter tube 11 are-threaded into the
top
of the casing. Installed. in the manometer tube is.a needle wave 12 for releasing air
from the autoclave as* e

Time distribution of exten;ive cosmic ray air showers
-PERIODICAL: Referativnyy zhurnal, Flzika, no. 10, 1962, 62, abstract 1OB464
(In collection: "Kosmicheskiye luchi, no. 3", Moscow, AN SSSR,
1961, 220 - 221, summary in English)
TEXT: As is known, the frequency distribution of extensive cosmic ray air
showers, investigated by cal ulating the number of shower events for equal time
intervals, obeys the Foision law. However, more precise data on the distribution
character may be obtained from the form of the time distribution function, i.e.,
the distribution of time intervals between ~he.shower events. Investigations into
this kind of distribution, conducted for large time Intervals, showed the a~pli-
cability of the Poisson law within the intervals concerned. The author studied
.the time distribution of extensive air showers for small time Intervals (up to
1 see) on a large apparatus of the Yakutskaya laboratoriya fizich. problem
(Yakutsk-Laboratory for Physical Problems) continuously recording up to 1500

Time distribution.of extensive cosmic ray air showers. A061/Aioi
showers per hours Showers with'~ mean number N=1.11.10 of particles were recorded.
The distribution of intervals, obtained experimentally, was compared with the ek-
pected Poisson distribution. It is noted that the distribution of intervals in
the first period (from 9.30 to 11.18) of the experiment which took place on March
5, 1960, is well described by the Poisson distribution, whereas great deviations
from the Poisson law are observed in the second period (from 11.20 to 13.10). The
necessity of repeating the experiments is pointed out.

ABSTRACTs Let M be a set in the Banach space X Let the distance
from x C.X to M be defined by f(x,M) inf 11x-y[1 . The
y FE M
set is called a Chebyshev setv if to every x 6X there exists
exactly one element y 6M so that 9(x,M) - y(x,y).
Theoremt If the unit sphere of the n-dimensional Banach space
Xn possesses no conic points, then each bounded Chebyshev set
M C:X is convex.
n
Theorem: In the n-dimensional Banach space X n the class of the
bounded Chebyebev sets is identical with the class of the
bounded convex sets if and only if the unit sphere of X n is
strongly convex and contains no c6nic points.
For the case of the general Banach space X only some evident
geometric considerations are given.
