ABSTRACT: It might be possible that the existence of the-Z-hyperon is the
cause of the observed differ8nee between the experimentally de-
termined mean lifetimes of A -particles which were oboerved in
cosmic radiation and in accelerators. In this paper the nuthor
examines this problem. AM-7 - n + 1t- decay has hitherto not
been noticed. Gell-Mann and Pais (Pays) herefrom drew the con-
clusion that for decays with participation of strongly inter-
acting particles the compensation rule ILS1 - I applies, which
forbids decays with a "strangeness" variation by two units
(Ref 1). It follows herefrom that for a strangeness of the
..Z1
-.particle of -2, its decay products would have to have the
total 3trangeness of -1. It follows from Q - 1 2 + 14/2 312 that

served. Therefore, the hypothe:3is 1431 - 1, as Okun' and
.Ponto-korvo (Ref 2) have shown, is no longer justifiable, except
when in decay the strangeness extends to norz~l particles.
Measurements of th6 mean lifetime of cosmic A -particleD gave

was obtained. The higher value in the former case could be ex-
plained by the fact that recording 0extends also to aucii Ao-par-
ticle s as are produced by *_E - A + 7-L0 decay. Therefore,
knowledge of the lifetime and the relative probability for
Z-hyperon production would be of great impDrtunce, because
then it would be po~;sible to decide whether the yield of-2-0-de-
cay actually quantitatively satisfies the higher value of the
lifetime in cosmic radiation. The author makes the attempt to
ve a rough estimate of lifetime and production probability for
-hyperonz for the purpose of explaining the difference in life-

ABSTRAVT3 In the present "Letter to the Editor" the authur discusues
the probability of the annihilation of the antiproton on
the deuteron and the probability of such reactions on the
basis of the material published In this field. Pontekorvo
(Ref 1) already showed that besides the ordinary annihilation
of the antiproton on one of the deuterium nucleons also the
so-called process of one-mesonic annihilation i + d --lo p T Tr_
(1) or j + d --,* n + ro (2) 12 possible. It is possible to
show that the relative probability of processeB+of this
kind cannot be less than that of the reaction + d ---~ p + p
if statistical corrections are taken into account. In the

detail and contains many expeTimental details). The second part
of the paper deals with the decay properties of hyperons.
Individual chapters deal with; The AP-hyperon (Vables 6 and 7
contain data on life-time measurements carried out by various
authors)~ the 1-hyperons, the cascade -B-hyperon, hyperon spin,
the lepton-decay of hyperons, the nonconDervation of parity in
the decay of byperonn, ant1hyperons. The next chapter deals with
the experimental verification of the selection rules

proton synchrotron at the 017a1 (Joint Institute of Nuclear Research).
Out of 140 Xo decays recorded, one four-yronged decay was found (at
8 M distance 2from the inner target). A photograph of this event is given
on an insert between pages 64 and 65. Tho tracks to be seen on this
photograph and denoted by A, B, C, D are discussed in the introduction,
ana the results obtained from measurements of the tracks are tabulated
(momentum, sign of the charge, angles). All possible ways of e3plaining
this event are next consideTed4 The conclusion Is that considering all
data of measurement as well as the CP-invariance, only the following

TEXT3 The present paper follows Bef. I in which the author jointly with
1. 1. Shirokoy has shown that a study of the dSCay Of Proton 4 antiprotons
into two pions may give information on the inner spatial and charge
.parities of the p-p system. Exrerimentally, the reaction ~ + p-;OX++Z- has
not yet been found. The author discusses all possibilities Of the
occurrence of such a reaction from the theoretical point of viev, an well
as -the results of a number of related publications. Supposing that the
annihila+ti*n transition matrix is strongly dependent on the isotopic and'
spin BtAteB of the p-p system, the annihilation process Is considerably
affected. Specifically, the fact 'that the 3 state predominateg in

annihilation leads to an increase in the mean multiplicity of the pions,
and since annihilation takes place primarily in the singlet state,
annihilatiom into two pions nay be suppressed (Ref. 4). In this case,
two-pion annihilation for the lover orbital states of the j-p system is
forbidden by the law of conservation of spatial and charge parities. The
question as to whether there is really such a close relationship between
the transition matrix and the state of the i-p system can be solved by
studying the reduced probability for annihilation from different states
of the p-p system, eDpecially from the S-states. The following ache=e io

ABSTRACT: The new rules revise the methods of inspection of welded
joints. Vew standards have been issued for crane hooks (r'OCT
2105-53 for solid hooks and roCT 6619-53 for plate hooks).
Building-up of worn-out hooks of wear does not exceed 10% is
acceptable. The safety factors for ropes have been reviewed.
Hoists for passenger transport require a factor of 9 instead
of 16. Cast iron supporting wheels are not allowed. The brake
torque reserve factors have been reviewed. A more refined
procedure is introduced for the stability analysis of derrick
cranes. The conceDtion of inherent stability is introduced
expressing the overturning moment due to wind action; numerical
stability margins are given in conjunction with analytical
formulae for computing the margins.
There are two figures.

TEXT: It was previously considered that the use of water a3 a shleldln4~,
medium in arc welding was Inefficient due to its oxidizing effect on the metal
and the increased hydrogen saturation of the metal. The authors present
calculational and experimental data characterizing the efficiency of using
water for protecting the metal against oxygen and air nitrogen during vllbrc-arc
building-up process. 'The protective effect of water was determined from the
saturation -of the metal with nitrogen and from the magnitude of the coefficients
of transition of C, Mg and Si from the electrode wire to the built-up metal,
Experiments were made using a vibro-arcBAT--5 3(VDG--5E) head on d-c of rever3ed
polarity from two or three aerles-connected rectifiers. Orade "20" steel
specimens of 40 - 50 mm were built-up (welding speed was 58 m/hr; amplitude
of electrode vibrations - 2 mm; operational length of 'the electrode wire:

voltage of the are and the frequency of electrode vibrations varied during the
experiments. Figure 1 shows the wire and liquid feed to the part to be welded.
Inductivity of the welding circuit was set-up depending on the frequency of'
ol.?rctrodo vibrations. A chemical analysis wan made of metal built-up with
60 and 70 grade steel -electrodes and an automatic OW-5 (KUMA-5) head, differi;-w,
from the VDG-5E head by a circular motion of the electrode -wire and by tho
liquid feed supplied in the fom of a hollow cone-shaped jet around the electrode.
The electrode composition was 0.74% Cil O.W Mn, 0.3C~% S1. The welding
conditions were; 18 v average arc voltage; 53 m1hr electrode wire feed;
building-up speed: 24 m1hr; speed of the circular motion of the electrode

Water h3z essential protective properties. Its use in building-up with vibrating
and non-vibrating electrodes reduces the saturation with nitrogen of the bull'.-
up metal and the burning-out from the metal of C, FZ, Si and other elements,
The degree of the protecting effect depends mainly on the quantity of the water
supplied to the are zone, and on the method and location of feed. The water used
In vibro-arc welding is converted into vaporous state in the are zone. Since
tbe contact of the arc with large water drops impedes the building-up process,
the jse of steam as a shielding medium supplied to the are zone Is recommended.
The built-up metal should be cooled by am individual water jet. 7here are

ABSTRACT: A considerable reduction of gas contents and non-metallic
impurities in steel and alloys has been obtained by
remelting in a special arc-vacuum furnace constructed
in the Metallurgical Institute of the Ac.Sc. USSR., a
sketch of which is shown on P 60 Ten reneltings of
ball-bearing steel under I x 10-1 mm pressure of
mercury at the rate of 0.6 kg/min resulted in a
reduction of oxide and sulphide contents by 40-50%.
The same steady 40-50% reduction of oxides and sulphides
has beel; obtainedoWer a series of remeltings (under
1 X 10--) to I X I mm pressure) of steel, previously
rejected because of its high contents of non-metallic
impurities. After remeltings it proved in many ways

Removal of oxygen in arc vacuum remelting of special steels
remelting of low-carben iron initially d*oxidized with various
dooxIdizors or initially not deoxidized, It was proposed that
oxygen In the form of stable non-notalliz inclusion could be
removed without partic.1pation of the carbon tRef.8). To check
those results the exper;--entz have been repeated. Ingots from a
.12-kg open induction furnace war* forged to 40-115 mm diameter rods
and two electrodes from each ingot war* prepared. These wore
resolted.in -an Arc -YAcuum furnace with a 73-Am diameter mould, on*
of each pair in -vacuum (10-2 to lo-3 mm HS) and the others in still

deoxidation. Both procedures were effective in r4moving oxygen,

The rate of melting of deoxidized iron van 430-400 and of

assumed to be CO. The results are shown in Table 2. In the
deoxidized metal the product of dissolved oxygen and carbon changes
little on vacuum remelting and remains well above even the
atmospberic-pressure equilibrium value. From the malting
conditions it appears that flotation (i.e. effects leading to the
concentrations of inclusions at or near the surface) nuat be an
important factor. In manganoBe-deoxidized metal, where the carbon
reaction in favoured by inclusions of x Foo. y XnO or Mno on which
CO bubbles can nucleate, both factors are Important; in undeoxi-

inclusions. It has been shown that repeated art remelting of
W 'A -15 (SbXh-15) steel (0.0045% 0, 0-018 5, 0.38 Mn) reduces the
inclusions greatly and that the effect Is not duo to increased time
in the molten state (variations represented by different injot
weights) but by the remelting process itself. The demonstrated
decisive role of mechanical factors as distinct from the carbon
reaction in vacuum arc remelting of special stools provides a
theoretical justification for applying the method irrespective of
