assist in the cf t-.~bc-nanizfacturing processes
in the Dnepropetrovsk economic and administrative region.
The following are mentioned: 1) scheme of an experimental
mechanism for turning Bemis in a roller beating furnace

pipes with the cores are supplied to the rest whoso jaws retair. *,he pipes during
the extraol;ion of the cores. The opening of the Jaws allows th:~ passage of the

One or two cor,~s may be extracted. The slariltane,nis extracti-;r, of two cores is
performed with the aid of the automatic tralley. 'No toTurs with jaws ar! opened

;ABSTRACT: Thi.s Author's Certificate introduces: 1. Amultiple-drE,ft mill for drawing
1pipe on a short mandrel. The unit consists of a tru.ck with a drive, unloaders, a
!stand with draw plate,, a receiving table with trougEs and a unit for setting the rods
~along with the mandrels into tubes. Operational reliability is i3iproved and servicing
is simplified by mounting the rods .6n a common movat-le truck and equipping them with
,spring compeni3ators. 2. A modification of this device equipped with a lever mechanism
ifor each drawing unit for clamping 'tubes, and a screw arrangement for moving the
,support.

AbSTRACT: At present there Is no sat:L;3factory theory of anti-
ferromagnotisim of transition metals. Lidiard (Ref.6) and
Matsubara (Ref.8) used Slater's ideas of alternating
potential In an antiferromalpietic. Hober (Ref.9) and
'Kasuya (Ref.10) employed Zener's new riechrenism of
ferromagnette and ant if erroituignet ir.- bindinE; in transition
metals. Both these theoril),13 provoked serious objections
(Ref.11). The present authors suggest an s-d exchange
model of an alit if erromagnet L(,. transition metal, similar
to that used for ferromagnetlos (Hef.12). A system

N conduction a-electrons, is considored. Tne present

ABSTIMT: The occurrence of tbermal equilibrium :.ii a system of
Bpin waves In an antiferromagnetic metal may be due to
various factors such as interaction with phonorts
collisions of spin waves wit'j,,i each othir, interaction
with conduction electrons The firE.t two mechanisms
were considered by Tsukernik (Ref 1). The present
authors have considered the i-,hird mechanism. The
calculation is based on the n-d exchange model

notation is the same ai3 in Ref 3. For the d-electrons
the usual spectrum of spin wave energies is obtained
while for the a-electrons the splitting of the
conduction band has already been described earlier
(Ref 3). The part of the energy operator which contains
triple terms in the second quantisation operators and
which describes quantum transitions due to the inter-
action of spin waves with conduction electrons leads
to the following equation for the mean frequcncy of
