and design of parts commonly used in machine design. Approximate
calculations of aircraft components are also covered. All
mathematical arguments and calculations are presented in such
a manner that the specialist in aviation or in other branches of
the armed forces can use them easily in practical maintenance,
work, engineering application, and production. To clarify prac-
tical calculations, numerical examples are given at the end of
each section. A large number of' well-known Russian scientists
are mentioned. There are 7 references, all Soviet.

ABSTRACT: The authors investigated the ability of in 1 3-trimethylsilylpropionate
to copolymerize with vinyl acetate methyl acrylate~, Zthyl methacrylate, acryloni-
trile, and styrene in the presence of azo -s-oru-tyraraitrile. It was found that vinyl
3-trimethylsilylpropionate can copolymerize with all the above monomers, with the
exception of styrene. When the content of vinyl 3-trimethylsilylpropionate in the-
starting mixture is increased, the yields and molecular weights of, the copolymers
are decreased., It was shown that, unlike the homopolymers, the copolymers are more
easily soluble.in/organic solvents and have lower melting points. The relative

TITLE: Laboratory, Pilot-plant, and Industrial-scale Tests of Zinc
Concentrate Roasting [Obzhig tsinkovykh kontsentratov (labor-
atornyye, polupromyshlennyye i promyshlennyye ispytaniya)]
PERIODICAL: Tr. Tekhn. soveshchaniya po obzhigu materialov b kip-

ABSTRACT: As a result of scientific research and design work performed
in 1946-1954 at the Elektrotsink Plant, a new method of Fluo-
Solids roasting of zinc concentrates was introduced on an in-
dustrial scale. The design of the furnace as a whole, and of a
number of its elements, was taken into account in developing
the method. Industrial operation of the furnace demonstrated
the following advantages of the new method and the new furnace
design. Higher quality ash was produced: extraction of Zn from
the ash in acid-50luble form was 2-3% higher, the content of
harmful impurities was lower by a factor of 1.5-2, and all the
ash was reduced to powder, not requiring screening and grind-
Card 1/2 ing. The concentration Of S02 in the roast gases was twice as

Laboratory, Pilot-plant,. and (cont,
h~lqh (7.5-9% instead of 4-4.2%). The unit productivity in concentrate roast-
3 useful volurne of the furnace per 24 hours was 7.5 times as high
ing per m
(1887 kg instead of 200-250 kg). No added fuel is required, as the process
yields heat equivalent to the generation of 0.7 t steam per ton of Zn concen-
trate. The furnace design is simpler and the working conditions are better.
For plants now in operation one may recommend the construction of large
furnaces if it is necessary to use the space where the old multiple-hearth
round furnaceshad stood. In this case it is necessary to provide for the pos-
sibility of regulating delivery of air along the line of motion of the concentrate-

TITLE: The Use of Water-Emulsion Varnish Grade 321-T
ICA
PERIOD &%L: Vestnik clektropromyshlonnosti, 1961, No.1, pp.18-20
TEXT: Water-emulsion varnish grade 321-T is an aqueous emulsion
of oil-resin-based varnish aiXd is an oil- and heat-resistant
light-coloured stoving impregnating varnish. The water-emulsion
varnish has better resistance to heat and oil and to fire than oil-
bitumen varnishes; it also has better binding properties and does
not damage wire insulating enamel. The water-emulsion-varnish is
made in a simple plant consisting of an emulsifier of 30 litres
containing a stirrer, a tank for heating the basic varnish and a
tank for storing the finished varnish. Tests showed that the best
proportion of film-forming component in the varnish is 30 to 35%;
if it is increased from 40 to 42% the drying time is much longer
and if it is reduced to 259,0' the turns are not sufficiently well
bound together. The conditions to be used in impregnating the
windings of electric motors were determined by tests on stators of
No-5 and No.9 frame sizes. Before winding the stators and

procedure for impregnating and drying stators was: first dip in
varnish for 15 minutes, drain for thirty minute.; and give first
drying for eight hours at 125 to 1350C; then give second dip in
varnish for 1.5 minutes, drain for 30 minutes and give second
drying for 10 hours at 125 to 1350C. This is the procedure now
used for treating stator and exciter armature windings. A longer
drying period is used for rotors. To avoid deposition in the
dipping tanks the varnish temperature did not exceed 40 to 500C.
Varnish that has once been precipitated cannot be re-cmulsified.
1,.'ater-cmulsion varnish binds the windings better than varnish
No.447. When it is required to repair windings impregnated with
water-emulsion varnish, they are first heated to a temperature of
80 to 1000C and can then be withdrawn from the slots, Generators
Of up to 50 kW and induction motors of up to No.9 frame size are all
now treated with water-emulsion varnish. Comparative tests were
made of varnishes No.447 and 321-T water-emulsion-. The electric

strength was determined by gradually raising the voltage to
breakdown; stators impregnated with the two kinds of varnish were
found to be of similar breakdown strength,namdY5 to 7 kV. Similar,
tests were made after thermal ageing for 15 days at 150*C and again:
the breakdown voltage was similar for both kinds of varnishl being
about 4.2 kV. However, it was evident that the windings
nish No.447 were not in such good condition as
impregnated with var
those impregnated with water-emulsion varnish 321-T. The two
kinds of varnish were similar in their resistance to water, but the
windings impregnated with water-emulsion varnish regained their
insulation resistance somewhat faster on drying. Tests were also
made on end windings which were *finished with enamel grade Cj3A
(SVD). They were found to have somewhat better properties than
end windings that were not enamelled. Because of this and the
better appearance, enamel SVD is used on end windings. There are
3 figures and 2 Soviet references.
