ABSTRACT: A method is proposed for processing gravimetric survey data
based on analysis of isoanotnaly gravity maps. The isoanomaly map is
put on a dielectric sheet, the interspaces between isoanomalies are
filled with conductors, and a potentiometer adapted for each interspace
Is attached. A point-shaped charge is moved above the dielectric sheet
which measures the current. Parameters of the gravity field are deter-
mined from the intensity of the induced current. This method permits
a continuous distribution of the gravity field, higher accuracy, and a
shortened processing to be obtained. Orig. art. has: 1 figure.

TITLE: On the Linear Correction of Transient Processes in
Finite-Bandwidth Systems
PERIODICAL: Radiotekhnika i elektronika, 1961, Vol.6, No.2,
PP-193-196
TEXT: The article considers an idealized linear system with
infinite attenuation in the stop band. An energy criterion is
adopted to estimate the intensity of the transient process occurring
in such a systemo The ideal frequency characteristics of the
system are assumed to be unity transmission in a band of frequencies
+ fl and zero delay over the band, with zero transmission outside
of the band, The response of the filter to an arbitrary waveform
y(t) is given by the Duhamel integral, The problem is to
calculate the waveform y(t) of duration T resulting in minimum
energy of -the filter response outside of the time interval in which
the waveform is actually present. The problem is solved in
functionals, leading to the Fredholm integral equation with
positive-definite kernel, Not surprisingly, the solution
obtained for the present problem corresponds to that obtained IX

ABSTRACT: This theoretical conclusion was verified experimentally: with a specified
overall vocoder channel band, it is expedient to have individual-channel bands of
different widths; wider bands should correspond to the Fourier coefficients with

correspond to h0i and hkt of the monoclinic system,
differ from the analogous equations of t1ae orthorhombic

change their values depending on the displacement of

in Pe form of moveable wires,relative to the lines

may be found on the instrument as the difference between
the ordinate of the h06 wire and the o5dinate of the

ing to these indices. The indices hk& may be found
in a similar way. Thus, the instrument may be used to

index X-ray powder photographs of orthorhombic and mono-
clinic crystals. Chrysotile is here used as an example,
although the parameters were known. Pata from J.W.Gruner
(Ref 3) were used for which Gruner hiiziself had found
a = 5.33, b ;= 9.24, c = 7.33 1, 0 = 13 0161 The metho

ABSTRACT: The proposed contactless overload relay utilizes semiconductors
and contains an input relay unit, R-C circuits with an adjustable delay, and an
output unit using electromagnetic slave mechanisms. To divide the controlled
heteropolar lines galvanically and thus insure relay sensitivity to the overloads
of both polarities, the relay contains two transistorized balanced amplifiers

In order that a frame loaded with forces consistent with the parameter P mav be
stable, it is necessary and sufficient that the basic system of the s lope -deformation
method be stable and that

For a practical computation of the critical parameter, the range of its variation
must be given from the outset; this range is later narrowed by means of successive
approximations with the application of criterion (*). This process of computation
coincides in each step with the evaluation of the determinant of the canonical cqua-
ti~ons of the s lope -deformation method with the aid of Gauss' algorithm. The
arti.cle is in line with the author's other works on the same subject [e.g., "Metody
opredeleniya sobstvennykh chastot i kriticheskikh sit dlya sterzhnevykh sistem"

Considerable success has beet achieved with insecticidal baits as a
mesas of controlling harmful insects. The usual methods of applying in-
secticides, i.e., dusting, spraying, aerosols, and insecticidal smokes,
,are not always fully effective, and in many cases their use is inconven-
A~nt since they require the removal of foods or other objects with which
bwans may come in contact from the area to be treated. Insecticidal baits
fisve two advantages: first, they bring the insects into close contact with
.the poisons, and second, if the bait is a food, the poisonr kill the in-
,sects through intestinal absorption. The use of insecticidal baits became
#wsible with the development of organophosphorus compounds -- parathion
Ithicf0s], diazinon, dipterex, malathion (karbofos], and others -- which
.iie used with sugar water, powdered sugar, and other sugar preparations
f6t the destruction of flies, and with food products for the destruction
.of-roaches. One of the more effective organophosphorus compounds is the
.tw.wly developed insecticide DDVF, which has the following structural for-

isno less toxic to flies than parathlon, b t in considerably less

Sugar-baited insecticides, however, fail to attract fruit flies. In
1952, it was found that certain protein hydrolysates had the capacity to
attract insects, and when used in combination with parathion, malathion,
~aad DDVF formed insecticides which were effective against fruit flies.
Ode of the more effective lures, whose action has not yet been clarified,
is methyl eugenol which has the following structural formula,

Methyl eugenol is marked by high selectivity, and attracts only male
friAt flies. The great power uf its attraction makes possible its applica-
tion in small quantities and over small areas.

TEXT: The present article is dedicated to the experimental confirma-
tion of the condensation of alkoxy-derivative metals, metal-organic groups
and silicon of the general farmula M(OR)n, (where M is a metal, Bilicon,
etc., R an alkyl or aryl group, n the valency of M), at the hydroxyl groups
of the polysiloxanes and also to the study of the mechanism of this conden-
sation. It is proven that the condensation of the polyalkoxyailanes with
polydimethylsiloxanes takes place only at the hydroxyl gromps of the latter.
The complex-catalytic nature of the solidification of the polysiloxanes at
room temperature is also shown. In order to clarify the mechanism of con-
densation at the free hydroxyl groups, the effect of certain admixtures on
this reaction was investigated. For example, by adding aluminum pyriaine

with butylate to polysiloxane or triethylamine (molar ratio of the amine
to the butylate of aluminum, 1:1), the reaction was considerably slowed
up and the nature of the formed products changed. If amine in "he ratio
of 2:1 or 3:1 is added, no structuralizing takes place at all. The authors
(Ref. 6) had already shown that when mixing polysiloxane rubber with alkoxy-
-derivatives of many metals and metal-organic groups, rapid gelatination
of the rubber takes place with the formation of high-molecular and in some
cases nonfusible products and products insoluble in benzene. In that case
it can be assumed that the reaction takes place at the outer hydroxyl
groups of the polysiloxane rubber. The condensation arrangement 6f the
hydroxyl groups requires confirmation since there are several variations
of the reaction, e.g., the break in the large polyBiloxane rings or chain's
with simultaneous bonding of the liberated ends with the structuralizing
agent. The interaction of metal alcoholates with two types of polysiloxan-
es was investigated. Table 1 shows the relationship of the aluminum buty-
late quantity needed for the complete structuralizing of the polysiloxane

is outlined and the structural formulae of the reacting compounds are
presented. The results of the indicated experiments point in favour of
the reaction scheme of the polysiloxanes and the alkoxy-derivatives of me-
tals at the hydroxyl. groups. It is stated that the reaction of polysiloxane
with butylorthotitaniumlis a hydrolysis of the latter by the moisture of
air to orthotitanic acid and subsequent condensation of this acid with
hydroxyl groups. Another possible mechanism is the formation of an inter-
mediate complex compound, metal alcoholate with the polysiloxane, as a re-
sult of the donor-accepting bond of the metal atom with the oxygen atom of
the hydroxyl group with subsequent detachment of the alcohol. As a result
of the experimental facts, the authors claim that it is easy to explain
the difference in the nature of the gels obtained from polydimethylsiloxane,
aluminum butylateland butylorthotitanium. The accepted assumptions on the
mechanism of the condensation reaction made it possible to use tetraethoxy-
silane as the structuralizing agent in this reaction or other polyalkoxy-

PERIODICAL: Kauchuk i rezina, 19600 1, No~12, PP~ 3-7
TEXT: In a previous work (Ref.D the authors dealt with the catalytic
reaction of structuralizing of polydimethylsiloxane rubber with alkoxysilaneq,
which takes place by condensation of the latter with the hydroxyl groups of
polydimethylsiloxane and separation of alcohol. In this acticle it is point-
ed out that the mechanism of the reaction has been only slightly investigated
and it is further suggested that the kinetic3 of the reaction be studied
during the period from its start until the moment of the spatial lattice
formation. Such an investigation was carried out by measuring the elasticity
growth of the benzene solution of the CKT (SKT) rubber after it had been
mixed with the catalyst and the structuralizing agent in a spherical Hepler
viscosimeter. It was shown that the elasticity growth was determined-only by
the growth of the molecule. Fig.1 shows that the growth process of the

TITLE: Synthesis of linear alumosiloxane polymers by silanol
condensation
PERIODICAL: Vysokomolekulyarnyye soyedineniya, v. 3, no. 6, 1961, 641-645
TEXT: Since no method han been described for the preparation of linear
metallosiloxanes of preset struoture, the authors tried to synthesize
these polymers by appl ing silanol condensation (Ref. 1: Kauchuk i
rezina, 1960, 1 ~. This condensation takes place on mixing organo-
silicon compounds containing the silanol group Si -OH with alkoxy
derivatives of metals, organometallic groups or silicon (e.g. aluminum
alcoholates, dialkoxy derivatives of the monoacetylac,,etonate, other
aluminum complexes, alkoxy derivatives of titanium, tin and iron, etc
Separation of the alcohol and formation of the metallosiloxane bond tak;
place under very mild conditions according to the following scheme:

used a bifunctional aluminum alcoholate with 2 reactive alkoxy groups,

Oving to its uniform electron density distribution over the ring, this
complex ifj more resistant to hydrolysis than the alkoxy groups. On treat-
ment with water, the alkoxy groups are hydrolyzed off, and condensation
yielding a linear alumoxane polymer takes place. A similar behavior was
to be expected in ailanol condensation. Polydimethylsiloxane (molecular
weight 3,000-50,000) having silanol groups at the ends of the chain was
used as reaction partner. The two components were mixed in benzene in the
required ratio and the polymer formed then precipitated with acetone. The
polysiloxane molecules of high molecular weight determined the basic

properties of these modified alumosiloxane derivatives (RAS), which are
modified by aluminum links. The time required for the reaction is
directly proportional to the molecular weight of the polydimethylsiloxane
derivative used. A comparison of the viscosities of MAS (Table 1) in
toluene and solutions of the initial siloxane indicates the increased
molecular dimensions of MAS. Their greater hardness is due to the
formation of donor-acceptor bonds between the aluminum groups of different
polymer molecules and to multiple coordination of the aluminum atom. The
oxygen atcm in the alkoxy group of the acetoacetic ester has the greatest
electron density and is able to form complexes. For.this reason the
ethyl and octyl esters of acetoacetic acid , having different complexability
were used. Hardness was determined thermomechanically according to
Kargin in the temperature range -600C to 2000C (at a rate of-40C per
10 min). The extent of intermolecular interaction is mainly determined
by the relative number of aluminum links in the chain. The properties
due to the aluminum links are more marked if the initial oiloxane in
lower-moleoular. The Al content of MAS depends only on the molecular
weight of the initial siloxane and not on the ratio aluminum complex/ailoxane
(26,300 -1-99 % Al; 3160 -3.61 % Al). The greater hardness of the second

polymer is due tn its higher Al content and the numerous Al links. The
above-stated comDositiori is confirmed by the findings that the polymers
are completely soluble in benzene and toluene, flow under pressure, melt
on heating and sinter at high temperatures. The residual compression is
also characteristic of structureless polymers. This is corroborated by
the viscosity (Table 1) and the presence of Al in these polymers.
Acetylacetone forms very stable acetylacetonates with the Al of many
aluminum compounds, splitting the Si -0 -Al bond, On treating MAS with
excess acetylacetone at room temperature (Table 2), the initial polydi-
methylsiloxanes were regenerated, which shows that condensation did not
take place: Si-OH +HO-Si Al 0 Si-O-Si + H 20. Heating of MAS to
> 2000C leads to reversible softening, which together with its resistanae
to pyridine, is not in agreement with the presence of a large number of
complex bonds H N/ V
