AUTHOR: Yagn, Yu.I., Shishmarev, O.A. 20-119-1-11/52 TITLE: Some Results of the Investigation of the Limit of the Elastic State of Plastically Stretched Pieces of Nickel (Nekotoryye rezul'taty issledovaniya granits uprugogo sostoyaniya plasticheski rastyanutykh obraztsov nikelya) PERIODICAL: Doklady Akademii Nauk, 1958, Vol 119, Nr 1, PP 46-48 (USSR) ABSTRACT; The authors describe the results of their experimental investigation of the limit of the elastic state for a plane state of tension which was generated by a stretching and torsion of thin-walled nickel tubes. A high exactness was aspired. The exterior diameter of the tubes was 5 mm for a thickness of the wall of 0,2 mm. The experiments were carried out under a direct load by weights, the measurements were made b~ mirror instruments. The determination of all points of the sought limit at a piece of the tube was inexact because of the remaini-ng action of preceding experiments. It is stated that reliable measurements are possible only ca. 10-15 minutes after the plastic deformat-ion, because before this time the creeping is too large. On none of the obtained limits the authors found angles, the existence of which is asserted by Card 1/2 many authors [Ref 3,5,61 - Some Results of the Investigation of the Limit of the Elastic 20-119-1-11/52 State of Plastically Stretched Pieces of Nickel There are 6 references, 2 of which are Soviet, 4 American.

The authors consider the effects of air bubbles on the gyro errors and describe a special installa- tion and method of filling.

A schematic diagram of ~:x such a transducer is shown in Fig. 1 of the E nclosur6. This moment can,be produced either by mechanical springs or by a special system which is called an~ "electrical springf.x The present paper describes a transducer with a potentiometric putputin which the Cdrd 1/4 L 12615-65 ACCE SSION NR: AT4046039 opposing moment Is obtained by mechanical springs. On the basis of a mathematical analysis, I the following conclusions are reached- 1. The output-signal of a transducer. having a mechanical spring Is directly proportional to the -voltage applied to the potenffo~-, meter.. 2. When the supply voltage to the gyrometer varieswIthin the limits. + 5%, the.~ magnitude of the output signal Is practically directly proportional to the voltage and varies within the limits + 0. 84% about its meam value, correspondingto, the nominal value of the supply voltage. 3. When the supply voltage frequency oscillatek within the limits + 2%, the magnitude of the output signal Is practically directly proportional to the frequency and changes within the limits + 1. 4% of the value for the nominal supply frequency. 4. The ranges of tolerance !or voltage and frequeacy can be computed, using two formulas derived in the paper, on the basis of a given range of.. toleiance for the speed of the gyromotor. 5. In order to obtain a high accuracy in such a transducer it is necessary to impose stringent requirements onthe supply sources (particularly the- ;-,V, supply frequency stability), 6. In 6rder to estimate the quality of production of such all instruments, It is recommended to use the concept. of the llaccuracy of productio as distinguished from the "accuracy of the Instrument", and to measure theau'tputparameters., of Instruments at nominal supply parameters which must he controlled during measime ments by high precision meters.

Contact failure is the most serious reliability problem in automatic pilot instrumentation. The design of-are-, liable contact is therefore discussed In detail and a few design examples are described.: ' ii ;f increasing the reliability by providing a second parallel contact to The possibility erformance and error is illustrated by otentio eter th ff t d it d m on ec an s e e p examlne p Card 1/3 F ACCESSION NR: AT4046040 specific examples. Ile reasons forcontact, failure are discussed,. and the case when t*d parallel contacts are used, one of which is displaced with respect to the other by either- one turn or a half a turn of the potentiometer winding, Is examixied In detail. In the first case, one turn between the contacts Is shorted and. this has no effect. with.windings having more than 1000 htrns since the tolerance in the winding Is usually. greater than I turn. The characteristic, reeolution (defined as the variation of resistance or voltage at the contact when the contact Is displaced by one turn) and accuracy.of such'a % potentiometer is also practically unaffected. When the contacts are shifted by'half a, turn with respect to each other, the aceuralcy of such a potentiometer Is iner eased in its middle range by a factor of two. The theoretical conclusions concerning the relative displacement of two parallel contacts were corroborated experimentally. The agreerne at between theoretl6al and experimental characteristics obtained cofifirms'the validity of the proposed method of decreasing the winding error of potentiometers In their middle'. range by displacing two parallel wiping contacts by half. of the distance between the turyisi' A detailed examination of the characteristie of a potentiometer which has two dlametrk~- ally opposed parallel wiping contacts shows that.the resolutloa and the winding error decreases by a factor of two throughout the entire potentiometer length compared with Card Card 3/3 ACCESSION NR: AT40,16041 S/2536/64/000/059/0138/0168 AUTIlOR- Sliislimqroy,_V.-Yu..(EngipgLqz!); Zakharova., L, It (Engineor)j UrazatyevILF., (Candidate of technical sciences) TITLE: A method of designing current-carrying wipers for potentiometers used in gyroscopic Instruments SOURCE.

'rho effect of the contact pressure of wipers is examined In deudl. Formulas for the minim al contact pressure assuring a reliable contact pressure are derived. For contacts between noble metals the contact prossure should be betweei 0. 2 and 1. 2G. ne problem of the constancy of tile contact cu,,j 1/3 ACCESSION NR: AT4046041 pressure with time is investigated. In this connection, it is noted that for small objects like wipers the effect of internal stresses due to thermal and mechanical processing can be relatively large. The effect of the natural frequency of oscillation of a wiper or the wiper assembly on the reliability of contact is examined, and it is concluded that the frequency of natural oscillation of a wiper must be about twice as high as the maximum frequency of the vibrations actually occurring. On the basis of the above codsiderations a method for designing the main parameters of wipers is developed which takes into account given operating conditions such as vibration and overload; in this design method a wiper is considered as a beam, one end of which is fixed and the other end of which, the point of contact, is considered to be supported. on rollers. Design formdlas are derived for arm-type wipers of constant circular cross-section having a flattened segment near the mounting place. The design formulas derived are conveniently summarl7ed in a Table, and their use Is illustrated in specific examples. The method shows that for given operating conditions and material the magnitude of the desired contact pressure uniquely determines the optimum value of the wiper diameter and length. The operating conditions as well as the wiper metal uniquely determine the optimum magnitude of the Card 2/3 ACCESSION NR: AT4046041 wiper bend inflection to be used. Following this design method the rellabillbr of potentio- metric transducers and, consequently, of the instruments where they are used, will be Increased. The method proposed can also be employed to design other types of current- carrying wipers like commutator brushes, elastic parts of central contacts, 9tc.

The two crystals are separated by a grounded plate, and the amplified crystal signals are fed to a synchronous detector. The presence of two synchronous electrical oscillations permits the use of a simple correla- tion method for suppressing the fluctuation noise. By this method a reference voltage being synchronous with the signal (synchrophone principle) is obtained, so that highly stable piezoelectric elements can be used as pickups at low sound Card 1/2 S/589/62/000/061/OOZ/005 A correlation method for fluctuation-noise....

PERIODICAL: Doklady All SSSR, 1958, Vol- 118, Nr 3, PP. 540,542 (USSR) ABSTRACT: Ascangel is one of the most characteristic representatives of true bentonites in the USSR (Askani Mine, M&kbarafte Di6trict, Georgiqn M)~ ~ lt8 highly disperse fraction is a typical alkaline MOLItmorillonite. Because of its properties this mineral plays an important r8le in the technique of trial borings. The isolation of colloidal fractions of ascangel is of great importance also for the following industries: foundry-, soap-, rubber-, paper-, cramic-, varnish- and color-, building material-, weaving-, perfume-, pharmaceutical, and many other industries (ref. 6,P). The coarsly disperse fractions of ascangel (contents approximatelY 30%) exert a negative influence on the colloidal properties of suspension. It sediments in the case of small concentrations (3,5 - 4 %). With increasing concentration (5 - 8 %) the mechanical resistance of the system increases only slowly and the tixotropic properties decrease. The Card 1/3 influence of stabilizing and peptizing reagents on coarsly Concentrated Ascangel 20-3-35/59 and highly disperse fractions shows very different results. Therefore the properties of the suspensions with coarsly disperse fractions can be regulated only with difficulties. Thus, the problem of a suited raw material for colloidal bore sus-Densions is solved by the isolation of highly disperse fractions of ascangel. The present methods are in-sufficient Since the chlorine salts of 2- and 3-valent cations are the most aggressive electrolytes (ref. 9) there is possibility of separating suspension phases of ascangel with small concentration of the electrolyte by means of the usual industrial centrifuges (UP to 3000 rev/min.) in a productive way. BaC12-solution was used as precipitator. After the separation of the dispersion medium a paste of the highly disperse fractions was formed. The paste was peptized with NA2SO4 in order to restors its colloidal properties. The obtained product, analogous to the American Akvazhel was called "enriched ascangel"..Separation of the coarsly disperse fractions (31 %) from a diluted ascangel-suspension was achieved by a vertical centrifuge. In order to avoid the formation of barium carbonate the suspension was first Card 2/3 acidified with HC1 to PH 6. The peptized paste had a PH - 6,8. Concentrated Ascangel 20-3-35/59 Water suspensions of enriched ascangel show highly tixotropic properties which they.retain within a wider range of concentration than the formerly used ascangel preparation "Askankoll" (fig. 2). The suspensions of the new preparations are durable and can be used in the above industries as active interstitial, binding, adhering, and suspending material, plastificator, fat substitute, etc. There are 2 figures, I table, and 11 references, all of which are Slavic.

The obtained product, which is similar to the American aquagel, was called "enriched ascangel". 0 CD The i-esults of the inveslUi-ation can be sunma-rized as follows. It is possible to isolate highly dis- persed ascangel particles vrith the aid of small Card 2/4 cuantities of BaC12 (25 mg-equ/100 g, or 2.5/'a' of the SOV/69-21-3-23/25 Obtaining and Investigating the Thixotropic Qualities of a Sus- pension of Highly Dispersed Ascangel Particles weight of ascangel). The separation of the phases of such a suspension is possible in a centrifuge (1,500 - 3,000 rmp) or by means of vacuum filtration. Coarse ascangel particles, which constitutue about 300/./ ascangel in the natural state, can be separated from a dilute suspension (- 2.5%) in a vertical se- dimenting centrifuge (1.620 rpm) of high capacity. Colloidal properties can be restored to the paste by the use of Na2SO 4 in stoichiometric proportion to the initially added BaC12. The obtained colloidal product represents a highly disperse fracture of true alkaline bentonite (ascan~,-el). Suspensions of 'len- t; riched ascangel" are characterized by conoiderable fluidity and thixotrODY. It can be used therefore, for the preparation of highly dis-perse drilling sus- Card 3/4 pensions and for other purpose-s.

SOV/20-126-2-54/64 TITLE- New Kinds of Organic-mineral 1,11licrofertilizers and Their Application Possibilities (Novyye vidy organo-minerallnykh mikroudobreniy i vozmozhnosti ikh primeneniya) PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 126, Nr 2, PP 421-423 (USSR) ABSTRACT: The arrangement of the electrolytes between the soil and the plant determines the assimilability of the elements serving as nutritive substances. This is one of the processes originating in the soil, which are connected with its absorption capacity. In many cases the equilibrium concentrations of the necessary substances are rather slight. This especially concerns the oxides of polyvalent elements in carbonate, alkaline and other soils. In theea cases the adsorptive distribution of these and other elements can be thoroughly changed by introduction of organic substances which form organic-mineral complexes with polyval~ant elements. Such complexes can be formed by oxidative destruction Card 1/4 of polymeric hydrocarbons (various waste of vegetable raw New Kinds of Organic-mineral j"icrofertilizers SOV/20-126-2-54/64 and Their Application Possibilities products). They are excellent substances for the formation of new kinds of microfertilizers mentioned in the title in easily accessible and assimilable form (Ref 1). Thus elements necessary for the plants can be introduced as non-ionizable complexes. They are absorbed by the soil to an incomparable weaker extent than the ions of the same metals. Further they are able to stand the conditions with sufficiently high pH-values. Chemically similar compounds were used mainly in foreign countries - so-called chelates (Ref 2). They differ, however, considerab'y b~- their influence on the plants. Figure 1 shows the dii.,~rams of potentiometric titration of organic iron compounds, called OP-V-Fe and OP-M-Fe by the authors, beside a diagram of FeC12 and FeCl 3- solutions with a 2 n-solution of NaOH. The first mentioned microfertilizers are not precipitated by this titration, but change their coloring and turn into colloidal solutions. This is their specific characteristic. Further investigations lead to the production of preparations Card 2/4 of higher value. In collaboration with M. V. Pirtskhalava the New Kinds of Organic-mineral Microfertilizers SOV/20-126-2-54/64 and Their Application Possibilities author developed 13 kinds of microfertilizers (Ref 1). Apart from polyvalent metals they contain carbohydrates with different molecular weight and optical activity, a composition of salts of organic acids, decomposition products of vegetable proteins et al. Some of them apparently play the part of biogenic stimulants. Experiments with these preparations indicated a large range of application under working conditions; fighting vine chlorosis, in which case Fe- and Mn-compounds proved the most successful. The resistance of the plants against the factors of surroundings such as temperature, soil acidity, soil salt content et al is increased.

Surface-Che mical Phenomena and Structuration in Ascangel'\Su spensions PERIODICAL: Kolloidnyy zhurnal, 1960, Vol XXII, Nr 1, pp 49-56 (USSR) ABSTRACT: The present paper, which was delivered as a report during the IV Vsesoyuznaya konferentsiya po kolloid- noy khimii (4th All-Union Conference on Colloidal Chemistry) in Tbilisi (1958) offers the results of a study of the effect of different electrolytes on thixotropic structuration in suspensions of--ascangel from the Ts ikhis-Ubani deposit in the Gruzinskaya SSR. The authors investigated the structural-mechanical properties of suspensions in dependence on adsorptive, electrokine tic and o-t;her surface-cheminal changes Card 1/5 68703 S/069/60/022/01/009/025 D034/DO03 Surface-Chemical Phenomena and Structuration in Ascangel Suspensions occurring during the interaction of ascangel with the electrolytes. The change of the structuro-mechanical properties of suspensions of electrodialysed or al- kali-treated ascan-el greatly depends on the change in character and content of easily soluble Al and Si compounds. Curve 1 in graph 1 shows that the quantity of exchangeable Al (basic and trivalent Al ions) formed during electrodialysis on the surface of the particles sharply increases with diminution of the pH value of the suspension, After prolonged interaction with growing quantities of NaOH the quantities of exchange- able Al and Si compounds in ascangel suspension are also on the increase. The content of dissolved sili- cates in alkali-treated suspensions increases by se- veral times at a temperature increase from 25 to 130 Cc The sharp break in the structuro-mechanical Card2/5 68703 S/069/60/022/01/009/025 D034/DO03 13ur-race-Ch"mical Phenomena and Structuration in Ascangel Suspensions properties of the suspension with the change of the pH of the suspension coincides with the beginning of abun- dant formation of exchangeable Al and Si (graph 1). The effect of the electrolytes (Na 2SiO39 Na4P207? (NaPO 3)6 9 NaA102, 'TaOH, Na C03, etc,) on the structura- tion of electrodialyzed asLngel suspension was different. On interaction of the suspension with Na 2sio 31 (NaPO3 )6 and Na4 P207 the formation of thixotropically fully reversible sbructures could be observed. These structures formed-as a result-of intensive adsorption of multivalent anions, the increase of the quantity of easily soluble Si compounds on the surface of the particles and the high values of the f -potential. Electrolytes enriching the ascangel pSrticle surface Card 3/5 66703 $069/60/022/01/009/025 D034/DD03 Surface-Chemical Phenomena and Structuration in -I'Lscangel Suspensions with various truly soluble and sparingly soluble Al compounds or depriving it of the easily soluble Si compounds and of the anions of the potential determin- ing layer favor the increase of non-thixotropic bonds between the suspension particles. NaOH and Na2CO3 occupy an intermediate position between these two kinds of differently acting electrolytes. In their introduc- tor notes the authors mention A.V. Dumanskiy Z-Ref. 1 7, who with his collaborators ascertained that the formation of colloidal systems with thixotropic proper- ties mostly depends on the lyophilic character of the disperse phase, P.A. Rebinder and his school f Ref. 2-7 maintain that thixotropic. structuration in aqueous clay suspensions with anisodiametric particles is favored by the highly hydrophilic character of most of the par- ticle surface, I,A. Uskov 4'Ref, 9 7 forwarded the opin- Card 4/5 C) L) 70 3 S/069/60/022/01/009/025 D034/DOO3 Surface-Chemical Phenomena and Structuration in Ascangel Suspensions ion that the change in the structuro-mechanical prODer- ties of clay suspensions depends on the excess amount of introduced electrolyte. According to S. Mattson Z-Hef. 10-7 dispersity, hydrophilic character, plas- ticity and other properties of Al-Si colloids are pre- valently connected with the chemical nature of the par- ticle surface which changes on their interaction with the elctrolytes.

Colloids were produced with di- and. trivalertiron, manganese, aluminum, chromium, cobalt and copper. Sols were purified by ordinary dialysis in cellophane sacks to pH 7-9 and specific conduct- ance of 10-3-10-4 ohm-1. cm-1. Only sols of trivalent iron were obtained even in the acid region. Sols were stabilized by the new type of stabilizers madefrom natural polymeric carbohydrates (wastes from plant materials) by oxidation and Card 1/2 L 18590-65 ACCESSION NR: AP4045406 thermal destruction. These stabilizers are complex mixtures consisting of the Lype of polyhydrdxy carboxylic acids of low molecular weight, capable of produc- ing water soltble and stable in alkaline medium complexes with polyvalent metals., These complexes are similar to metal-EDTA Complexes, but are much more stable. These stabilizers enable production of ferric hydroxide colloids up to the concentration of 119 g/1. Further increase of the concentration of sols Was done by evaporation at 50- 600C. Without exception all sols of polyvalent metal hydroxides were negatively charged, which is characterized by-the nature of the stabilizer. All these sols are polydispersed and consist of spherical particles. Their particle size ranges from 10 to 460 m Orig. art. has: 2 tables and 2 figures. ASSOCIATION: Institut khimii AN GSSR im.
