ABSTRACT: This AuLhor cr,rLiffcate introduces a method of manufacturing composite
billets from powder nia(crials by hydraulic pressure. In order to improve the quality
of the product, first Hit- billet of the base material is compacted. This billet is
then machined to obtain i1 rOUgh or corrugated surface. The machined billet is placed
in a mold of larger diami,rer, the mold is filled with powder of the cladding material
and Is pressed again. [WW)

TITLE: Synthesis of Cis and Trans Homocincho Loipone (Sintez tsis-

PER.10DICAL: IZVe3tiya vysshikh uchebnykh zavedeniy. Khimiya i khimichesk

ABSTRACT: The authors extended the earlier (Refs 1-4, 6, 7) devised
synthesis scheme to the compounds of indole structure, as far
as alkaloids of this group are of theoretical and practical
interest as well (Ref 5). Homocincho loipone and homo mero-
chinene are of importance for the synthesis of the alkaloids
of the indole group according to the scheme mentioned. The
synthesis of homocincho loipone described in the present paper
was carried out on the basis of the diethyl ester of the
p-(af-cyan)-propyi glutaric acid. This ester is the most im-
portant semiproduct in the synthesis of the alkaloid emetin
(Refs 6, 7). By hydrogenating the said ester 4-carbethoxy
methYl-5-ethyl-piperidone-2 (by-product in the emetin productl~f
is obtained in 2 isomeric forms: 1) Crystalline (11-a), and
Card 1/4 2) Oily (II-b). The synthesis with these two substances was

carried out separately. The reduction of the said piperidone
with lithium aluminum hydride leads to 3-ethyl-4-(P-oxy ethyl)-
piperidinea (111-a and b). The crystalline piperidone un-
soluble in ether was red~oed in dioxane, the oily one in ether.
By the action of thionyl chloride upon the hydrochlorides of
the said piperidines hydrochlorides of the 3-ethyl-4-(P-ethyl
chloride)-piperidines are formed. Without isolation these are
transformed into 'N-acety1-3-ethyl-4-(P-ethyl chloride)-
piperidines (IV--a and b). When treating the lat-ter with potas-
sium cyanide N-acetYl-3-ethyl-4-(P-ethyl cyanide)-piperidines
(V-a and b) are formed. The saponification of these piperidines
finally yields 3-ethyl-4-lp-carboxyl-ethyl)-piperidines, i. e.
homocincho loipones (VI--a and b). Chlorine aurates of homocincho
loipone were synthesized: a) from the crystalline form of
4-carbethoxy-methyl-5-ethyl-piperidone-2 (II-a) with a
melting point of 174.4-el750; b) from the oily form (II-b) with
a melting point of 194.5-1950. The structure of the synthesizea
substances was checked by comparison of the intermediate
products (III-a and b) with 3-ethyl-4-(P-OxY ethyl)-piperidine
(III-v), which had been synthesized by way of the merochinene
Card 2/ 4 stage from natural quinine. As is known, the plperid~r_e T~r- 4- -t e

of the cinchona bark-alkaloids maintain their cis configurati..,n.
Table (P 48) gives the characteristics of the compounds
synthesized. Infrared spectra (Fig p 48v taken by Yu. N.
Shenker) proved the identity of the synthesized substances
mentioned (III-a, b and v) with those from natural quinine*
Based on these spectra as well as on the melting points the
authors arrived at the conclusion that the homocincho loipone
synthesized from the semi-product corresponds to a cis-con-
figuration, whereas that from the oily type corresponds to a
trans-configuration.

TITLE: The Design of Tapers for the Symmetrical Magnetic Wave
in a Circular Waveguide
PERIODICAL: Radlotekhnika i elektronika, 1961, vol.6, No.2,
pp.228-233
TEXT: The problem is to design waveguide tapers for transmission
of the Hoi-wave in circular waveguide with minimum conversion loss.
The method used is based on the authors' previous results (Refs.1
and 3) (studied also by H.Unger, Ref.2). The treatment of
critical sections is based on the authors' previous work (Ref.4).
The method is based on the now well-known analogy applying to a
certain approximation between the problem considered and that of
finding the optimum form of variation of transmission line wave
impedance for a matching section between two lines with differing
wave impedances. The precision of the method depends on
neglecting the difference between the wave length of the Hol-
and H02-waves in the waveguide and in free space. Under these
conditions, the waveguide taper is calculated on the basis of
optimal results known from transmission line theory. Two cases

are considered, one with the absence of critical sections, the
other in their presence. The results obtained show that the
approximation used is valid in the former case. To handle the
latter case a more exact approximation, involving greater
calculations, is given, This modification, being more general, is
also applicable to the case of absence of critical sections but the results
are not more satisfactory than the simplified method applicable to
that case, There are 4 figures, I table and 8 references:

Abstract XLVIII. In amoniacal media, in the presence of Comple-
xon III, action of H202 on salts of Fe(3+), Al and Th,
brings about a quantitative precipitation of only Th
(after 30-60 minuted). Precip-itation of Fe and Al does
not take place even af*C'er several days. On precipita-
tion of Th in the presence of Fe, Al and other elements,
the readily filterable precipitate is washed with water,
calcined and weighed as Th02- In the presence of 10-
fold excess of Al, reprecipitation is utilized. Th can

dissolution of the precipitate in HC1, using pyrocatechol
violet as an indicator (RzhKhim, 1.955, 5763)- In the fil-
trate Fe is deternined p7avimetrically, after removal of
H202 by boiling, and precipitation with alkali in the
