TITLE: On the problem of pressing rate In die-casting machines
PER10t,)ICALi Liteynoye proizvodstvo, no. 1, 1963, 10 - 11
TEXT: To vary tM ~;ressing rate during die-casting, it is necessary to
change over from the differential feed of the hydraulic fluid to the eylinder to
the non-differential feed. An accurate determination of the change-over moment
requires a device which measures the rate cfpressing. A prototype model of a de-
vice determining the average speed of the plunger over a distance of at least 10
mm has been developed by the Novosibirsk "Siblitmash" Plant. The time intervals j
In which the plunger travels the necessary section of stroke are determined by
two contact pickups which are mounted on the path of travel of the preas'plunger.
The authors present a brief description of operation and a block diagram of the
device. There are 2 figures.

TEXT: Alumosilicate -,,atalystj3 used for the cracking of Iiydrocarbons have
an acid character-. The type of acid and the role of the various acids upon
the catalytic process have hitherto not boen clarified. V. A. Chernov
(Ref. 7) showed that in montmorillonite alumina, besides proton exchange,
also an exchange o-f aluminum ions is possible, and that alL.MIna can be,
regarded as an alumin salt of alumosilicic acids. The prtc!sent paper deals
with the ion exchange rf an alumosilicate catalyst in aqueoua salt. solutions
of alkali metals, A commercial catalyst (14.01%A1,)0,, 84.6()%Sio 0.36'/"ONa 0

conducted with NaCL U01, and sodium acetatesolutione of alfferent cart-
centrations. The acddity oause-I by the exchange of the alkali. metal for the
proton in the catalrst was determined by a method of V. A. Chernov (Ref. 8).
The ion exchange wa;3 determinel by potentiometric titration of the Sol-iticm
(after two days, vigorous shaking with the catalyst). The rosults obtained
show that the amount of the exchanged protons is much smallor than thal cf
the aluminum ions. After the exchange reaction, aluminum wao detected in
the NaCl and LiCl solritions, while this was not the j7ase with the sodium
acetate solution. Thiv is due to the fact that aluminum acetate hydrolyzes
immediately on the surface of the catalyst where It 44a depo,aited as aliLmn-frium
hydroxide, an equivaient amount of acetic acid being dissolved. Experiment
and calculation show that the maximum amount of the hydrogen and aluminum
ions of the catalyst exchanged. by alkali metal ions is practically independ-
ent of the type of the latter (i.e., the values for Li and Na ions are
practically equal). For the above reason, the amount of acetic acid
forming from the sodi-ara acetate solution (luring the exchange of the icns
of the catalyst for Na ions corresponds to the sira of the equivalents of
the exchanged hydrogen and ajuminum ions of the catalyst- 1here are

PERIODICAL: Zhurnal obshchey khimii, 1950, Vol. 20, Nr 6

ABSTRACT: Of the derivatives of prinary aminee only the dinitro-subatituted
ones were known (Rof 1). One of the authors rynthotizod the
corresponding anilinederivativen and other primary aromatic amines
(Refs 4,5)- However, the nature of these compounds was not in-
Yestigated in detail as their yields were toosmall. In order
to investioate similar compounds more closely the authors elabo-
rated a method of 3~,nthe3ie of the derivatives of aniline and of
other amines; in some cases they obtained consilerable yields,
and the authors could investii,-ate their condensability with aro-
mantic amines a-nd compounds containing active methyl groups. The
condensation of the monoanils with aromatic amines was carried
out under different conditions: in acetic acid in the presence
of hydrochloric acid, in acetic anhydride in the presence of
Card 1/3 hydrogen chloride and in pyridine in the presence of hydrogen

chloride. Only in the last mentioned case a color change
occurred, which could be taken as an indication as to the nature
of the process of reaction, however, no definite result could
be achieved. The investir,-3Ltions carried out of the monoanils
of glutacone aldehyde showed in any way that they are of ampho-
teric character. Their condensability with compounds having
active methyl groups can serve as indirect proof of the structure
of thqobtained monoanils. Thus the monoanils of glutacone alde-
hyde are investigated as derivatives of aromatic amines. It was
shown that the unsubstituted monoanil &nd the monoanils of
glutacone aldehyde with nucleophilic substituents in the aro-
matic nuclei do not enter the condensation with aromatic amines.
The condensation of some nonoanils with the methiodide of
2-methyllben2thiazole was carried out, however, the structure of
the initial products could not be determined. There are 2 tables
and 9 references, 3 of which aro Soviet.

ABSTRACT: This work investigates the character of the distribution of
the colloidal silicic acil a+epre sent at ive of a new glass of
intensifiers in sodium-butadiene rubber. This test object also
was chosen for the following reason: Of the same raw material and
also by the same method, only varying of the conditions of the
technological process# samples of colloidal silicic acid with
essentially different reinforcing effect can be produced. From
this the possibility of the comparison of active and inactive
fillers results. For the performance of these experiments a

Colloidal Silicic Acid as Filler of Synthetic Rubber
reinforcing action in rubber sorts of oodium-butadione rubber
was produced. The chemical composition of theae samples prac-
tically was equal and they also differed only very little with
regard to the specific aurfacet pH9 and various adsorption
characteristics. But the rubber mixtures produced on the base
of sodium-butadiene rubber, which contain the samples mentioned
have an essentially different structure of the mixture and also
essentially different physical-mechanical properties of the
vulcanisates. The degree of the structuring of the filler in
the mixture is characterized by the lixivation coefficient which
is determined by the share of the filler, which passes over
into the basic solution, in its total content in the mixture.
A diagram illustrates the dependence of the lixivation coefficient
on the rate of filling for samples of colloidal silicic acid
of the highest or lowest reinforcement coefficient reap. (active
reap. inactive samples)* The most active silicic acid is
leached out much easier than the inactive one. The higher the
lixivation coefficient is for a given system the stronger
Card 2/3 marked are also the strength properties of the vulcanisate.

The activity of the colloidal silicic acid can be decreased
considerably by heating at 6oooC. There are 4 figures, 3
tables,and 7 references, 3 of which are Soviet.
