dices 1 and 2. If stresses arising in the vicinity of collar-reinforced ports
are to be determined, their distribution is more reliably est-&bliahed by tensio-
metric measurements, particularly in large reactor vessels where the fabrication
is limited by the maximum weight of ingots so that It is Impossible to reinforce
the ports in conformance with.the code. A beending moment is also introduced in-
to the vessel wall at the points where the vessel. rests against supports. Prom
the viewpoint of material stress it is advisable to distribute the effects of
the reaction around the entire circumference of +brie vessel, so as to avoid for-
mation of isolated forces and moments. In very large and heavy reactors operat-
ing at comparatively low internal overpressures the reaction effect on the over-
all wall stresses is greater than In reactors operating at overpressures of 60,
100, or more atm, since the total weight represents but a small percent-age of t1r.
resultant axial force given by the overpressure. It has tc- be emphasized that
stresees involved in all the above cases qre the so-called shell stresses, which
have a linearly variable pattern through the wall thickness and, for a given per-
missible stress, prevent an economical utilization of the mechanical properties
of the vessel material. It is, therefore, necessary to avoid sources of this

stress by maintaining a uniform wall thickness. In addition to the shell
stresses, narrow, local peaks due to the concentration of lines of force arise
at sudden changes of the wall thickness and in the transition areas of the wall
into ports. In determining their magnitude we have to depend on tensiometric
and / or photoelastometric measurements. The problem of stress concentrations
in the wall is of similar significance, since it has to be considered that ir-
radiated material changes its mechanical properties after some time and the dan-
ger of brittle fractures arises. 3) Increase of stress in ths transition area
between the vessel and the lower head. Increased stresses can occur in the
transition area between the vessel and the lower head. A large majority of re-
actors, existing or projected, therefore, use a hemispherical or elliptical low-
er head rather than a flat one, Greater fabrication difficulties required by
the former are compensated for by their lower weight, smaller deformation due to
internal overpressure, and a more uniform cooling and / or heating at shutdowns
and startups. 4) Distribution of stresses in the vicinity of Inlet and outlet
pipe penetrations. The stress distribution In the penetration-weakened part of
a reactor head presents a 'Laborious calculation task. In a hemispherical head
(Fig. 4), -the transition stresses from the unweakened to the weakened part and to

the flange can be determined by-a rough caloulation. The mean vallue of the in-
creaae of the centerline radius in the free and weakened part of the sphere, due
to the overpressure p, is larger by a value T t a than that of the unweakened
part. From the condition of continuity of the deformed area and its firs" de-
rIvative accordipg to an independent variablei~, the marginal forces xl,2 and
moments D11 2 can be determined and on their basis also the mean values of addi-
tional stre'sees. A more accurate idea of the stress distribution in the weskmed
part of a hemispherical head can be obtained by comparing it to a system of me-
ridian ribs of variable thicknesses, connected by parallel rings. This involves
the solution of a system of linear algebraic equations that can be handled only
by a computer. Results obtained can then be verified by tensiometric measure-
ments which are already being conducted at several Czechoslovak research facili-
ties. 5) Thermal stresses due to uneven distribution of heat across the wall
thickness and the vessel-body length. In calculating the atrength of reactor
vessels, the problem of thermal stresses ie of great significance. Temperature

where ai and bi are "sical constants. With the rotation symmetry preserved,
the magnitude of thermal stresses can be determined by the solution of two one-
dimensional problems. At given'coeffioients of heattransfer on the inner and
outer surfaces of the vessel wall, the distribution of heat at a steady state Is
given by the solution of the differential equation ALJ t- -1 . In thin-walled

of the zero resultant of force Along the cylinder axis. The above relations and

is, therefore, necessary to place a compensating insert between the head and the
vessel, or to ensure that at startups and / or shutdowns a certain maximum tem-

triethyl aluminium and of dieth~i a'luminium- chloridel'using such experimental technique
as would limit to a mini= the possibility of contamination of the substances to be
measured. Whereas these compounds are industrially important, there is little pub-
lished data on their vapor pressure. The dynamic method was used to measure the vapor
pressure of these two substances by determining the boiling point in a vacuum distil-
lation apparatus. An equation for vapor pressure was derived from the measured values
which were used to compute the normal boiling point, the molar-heat of evaporation#

As the body is not stimulated spontaneously to form an effective rate of resistaAce
against micro-organiame during chemotherapeutic or antibiotic measures it must
be helped. otherwise relapses-occur due to resistant strains. The RES can be
stimulated by injections of sterilised cowls milk intrvauscularly as the most
easily available substance for this purpose. It is given in doses of 1.5. 1.0. 1.5
2.0. to 2.5 ml. every 2nd day in children up to one year and double those doses in
older children. The authors inaugusated this method in the most deplorable of
all relapses, those of purulent meningitis, in a child after the 3rd relapse. It
is given also to children with resistant p1siocytosis in the CSF after adequate anti-
bacterial treatment. Within 9 days the call count to normal and relapses coul4
be suppressed by the method although antibacterial treatment was stopped simul-
taneously. Mention is made of 5 cases; 2 meningococcal, 2 H. influenza@ and one
in which the micro-organioni could not be Identified. Bloch - Amsterdam (XX, 7,80

(Czech. patent cl. 421, 4/13, 42h, 20/01, no.99447,
April 1.5, 1961)
TEXT: The patented pneumatic rece'iver is based on the
schematic circuit of an American receiver. It consists of a
chamber, one wall of which is made of a material transparent to
infrared radiation. Inside the chamber an absorbing element
periodically receives infrared radiation through a shutter and is
thereby heated, which raises the pressUre of the gas in the
chamber. The pressure change is picked up by;an elastic
reflecting diaphragm. The surface of the diaphragm is fully sealed
.and it is a component of an optical system consisting of a
meniscus lens, a plane grating with transparent and opaque bands
of equal width, a condenser, a lamp, and a photocell with mirror.
If the diaphragm in flat the upper half of the grating illuminated

by the lamp is reflected from the diaphragm and gives a reflection
in the lower half of the grating. The transparent bands then
coincide with the opaque, and little light reaches the photocell
from the mirror and the current in the circuit is low. When the
diaphragm is deformed by pressure, it becomes convex or concave
and more or less radiation reaches the photocell, giving more or
less current. The current is then amplified and recorded in the
usual way. The chamber is connected with the internal space by a
capillary so that rapid changes in the pressure do not alter the
shape of the diaphragm. obviously the backing surface to which the
membrane is fixed should be very well finished and accurate so as
not to introduce errors into the light distribution. Hitherto the
backing has consisted of hardened carbon steel, which required
prolonged heat-treatment, accurate grinding and polishing and was,
moreover, rapidly corroded during the process of degreasing in an
ultrasonic field. This defect affected-the performance of the
receiver. In the device patented the backing surface is made of
easily worked minerals, whose surfaces do not corrode.

Abstract-: Author describes an apparatus that he designed for
evalua n of bioelectrical potentials. Circuit is based on an
integrating amplifier. Negative feed back is from amplifier
output to input. Desired voltage in capacitor starts blocking
of the oscillator. Resulting pulse unblocks the transistor
parallel with capacitor and discharges it. Circuit is linear,
but sensitive to temperature. Transistors in blocking oscillat-
ors nrovide returning of cores to initial state. Output pulses
are recorded as a series of short deflections; every t-enth de-
flect-ion is recorded with greater amplitude. 7 Figures, 2 West-

Abstract [English summary modifiedl: Changes to tolerance to hypoxia which
occurs during closed-circuit breathing in 8 healthy men aged 18 to 27
during 5 days' total fast were minimal; there was some lability and wider
individual scatter; training seemed to play a role; the lack of expected
decrease In tolerance is attributed to concomitant slowdown of metabolism
due to fasting so that tolerance remains essentially unchanged. Six tables,
