determined colorimetrically. Satisfactory yields can be
obtained only on a rapid addition of the oxidizing agent.

TITLE: Polarograp ic Study of Hydroxi-triphenyl-methane
PVestufts N
FMIODICAL: Chemicky pAmYsl, 1960, Nr 3, pp 129-132
ABSTRACT: The authors present a detailed contribution to polaro-
graphic investigations of hydroxi-triphenyl-methane
dyestuffs. The literature mentions that the reduction oL
the dropping mercury electrode of trihydroxy-triphenyl-
methane (aurine) and its substituents, proceeds in tNo
distinct mono-electronic waves. The authors offer t.ae
following electronic explanation: in mesomerie stru,3ture
I, the dyestuff loses its quinone configuration and
acquires a positive charge on the central carbon atom.
Simultaneously oxygen acquires a negative charge. During
reduction an electron is taken up by the central carlton
atom, producing a free radical of structure II, In the
second phase an additional electron is taken up producing
the unstable form III.,having a lone pair of electrons
with a negative charge. This is stabilised into the
anion of the leuco-base by acquiring a proton. The

two-step reduction is therefore explained by the existence
of a free radicle. The authors have studied the
polarographic behaviour under neuttal, alkaline and
acid conditions. The most characteristic two-step waves
were obtained in a neutral medium ;~.hereas acid.-Le
conditions suppressed it. Under -lkaline conditions
a not very well developed one-step dielectronic wave
was obtained. The authors have established that basic
dyestuffs, such as malachite green, show analogous
polarographic properties to aurine. Two independent
mono-electronic waves were obtained under neutral
conditions. The authors have also established that the
peak of the polarographic waves dependB to a high degree
upon the quantity of ethanole used as a solvent. They
conclude that a standard solution of aurine undergoes
a structural change, which manifest itself by decrease

ABSTRACTz The favorable influence of tracer elements upo:.% the breediN;

emphasized (Refs 1-4)- In spite of the well-kn:,wn important role
of molybdenum in the life of higher plants (ReJ's 6-14) this
effect has been little investigated. It was tho aim of the
author3 to observe the changes of soil microflora in the ca3e
of a molybdenum introduction into peat soils. In this
connection they wanted to determine the amount of NPK-elemeats
accumulated in the plants (mineral nutrition r1trogen,

that molybdenum promotes the absorption c N11Y.Aements and tLe

without infeed wheels on a ceramic binder of a hardness from M3 I;o CM 1 (SMI)
mid a grain size of 80 - 100 are used. Steel parts are ground wi.th wheils from

given dimension is reached. In grinding with fine dressing of tae wheel the
grinder Is equipped with a special device which makes it possibliq to dress the
wheel at a longitudinal feed of 0.01 mm per Dne revolution of tk.,a wheel. Wth
this method the allowance amounts to 0.04 mm, the wheel speed U 35 m/sec, com-
ponent speed 4 - 7 q/min, transverse feed 0.01 mm per double molLon and longi-
tudinal. feed 3 - 0.5 mm per one revolution of the component. Tta wheel is dressed
at a longitudinal feed of 0.01 mcVrev of the wheel and a depth or 0.01 mm. Grind-
ing with graphite wheels is based on the method of grinding witk.-.,ut infeed. The
components are ground with wheels on a-bakelite binder with gralitLite filler having
a grain size of M8 and a hardness of K3 or CZ 3 (SM3). These miethods of fine
grinding increase the efficiency and make It possible to automate finishing opera-
tions. There are 4 figures.

TOPIC TAGS: metal forging. forge press., hot forging, metal industry
ABSTRACT: Owing to the conical and spherical shapes of mold bottoms, the production of
hollow forgings normally involves the wastage of as much as 5-7% of ingot vietal. In this
connection, during 1963-1964 the Bolshevik Plant carried out a study of the ;ossibility of
producing hollow forgings of the centering-iEj -type without having to wrap the bottom part of
the ingot. It was found that this can be accomplished by using a core punch vrith a diameter that
is 50 min greater than the diameter of the cone-shaped part of the Ingot bot0m. Then the
wastage of metal can be reduced to 1. 42-1.48% and the labor-consuming as viell as relatively
unsafe operation of trimming the ingot bottom can be eliminate& The residting blanks can be
