The biggest installation in the world for continuous steel casting was put into operation at the Stalinskiy metallurgichaskiy zavod (Stalino Metallurgical Plant 9 a calcining process in quaeiliquid charge was introduced at the Nikitov- skiy rtutnyy kombinat (Nikitovka Mercury Kombinat), production of heavy automatic lathes of the type K)K-36 (KZh-,36) and KA-37 (M-37) as well as K >R-,25 (M-25) was started at the Kramatorskiy zavod tyazhelogo atankostroyeniya (Kramatorsk Plant for Heavy Machine Con- struction and the production of a new rotary excavator with an hour output of looo m3 was started at the Stalinskiy mashinostroytellnyy Card 1/4 The Plants of the Stalinskiy sovnarkhoz 5/026/60/000/009/005/006 (Stalino sovnarkhoz) Do Not Comply With B015/BO58 the POCT (GOST Standards) zavod im. 15--letiya LKSKU (Stalino MachLne Construction Plant imeni 15th Anniversary LKSUU). It was however2 established that some plants of the Stalino sovnarkhoz do not pay enough attention to quality-qAand the activity of thes4 plants was therefore investigated by the Stalin- skaya gosudarstvennaya kontrolinaya laboratoriya po izmeritellnoy tekhnike (Stalino State Control Laboratory for Measuring Technology). The deficiencies established thereby are mentioned in the present paper) and it -is stated that a deviation from the standards laid down is "main- ly the reason for a deterioration of quality. The following plants are mentioned and criticized: Konstantinovskiy zavod ogneupornykh izdeliy "Krasnyy Oktyabr" (Konstantinovka Plant for Refractories "Krasnyy Oktyabrl"), YasinovJ-s-klyzavod gornoprokhodcheskogo oborudovaniya (Yasinovataya Plant for Mine Sinking Equipment), Slavyanskiy armaturno- izolyatornyy zavod im.

The plants neglaot the following standards in the specification Card 2/4 The Plants of the Stalinskiy sovnarkhoz 3/028160/000/009/005/006 (Stalino sovnarkhoz) Do Not Comply With B015/BO58 the POCT (COST Standards) of drawings: "System of Administration of Drawings" and "Drawings in Machine Construction". A change of the OCT(OST) 10210-40 standard takes place at the "Krasnyy Oktyabr"I Plant and there is no OST NKTP 5853/140 standard "Methods of Measuring the Blunting of Angles and Ribs in Re- fractories" at that plant. There are various inaccuracies in the tech- nical documentation of the Yasinovatays, Plant, with reference to GOST 977-53, GOST 1284-45, BH-46-51 (VN-46-~-51); in some a.;:awings, for example, the weight of individual parts is not mentioned OK1-13-0101 (DKI-13-0101), AK4-148 (DK4-148)),,some drawings of bushes of the type ARI-0212 (DK1-0212) and lids of the type AKI-0206 (DKI,-0206) are used without introducing the essential modification; technical references for the crusher of the type AA ~-lM (DDZ-lM) are missing. At the Plant imeni Artem) articles are produced according to a modified GOST 2634-44 standard, instead of the valid GOST 2634--59 standard, and certain notes are missing in the drawings for suspension insulators of the type M-4-5 (PM-4-5)- Furthermore, technological discipline is not kept up in the plants being criticized, i.e.2 the production process is modified arbitrarily, and the quality of production is thus impaired.

TITLE: Some Organosilicon Liketodicarboxylic Acids PERIODICAL: Zhurnal obshchey khimii, 1961, Vol- 31, No. 1, pp. 234 - 238 TEXT: Following the paper of Ref. 1 on the acylation of organosilicon compounds,-the authors in the present paper studied the synthesis of organosilicon diketodicarboxylic acids. Phthalic and maleic anhydride were used as acylating agents, and methyl-phenyl-siloxane groups were introduced into the molecule of diketodicarboxylic acids at the same time. When changing the ratio of the acylation product (I) to methyl-phenyl- dichlorosilane in the hydrolysis process, organosilicon diketodicarboxyl.ic acids resulted, which contained X methyl-phenyl-siloxane groups (X - 1, 2, V~ 3, 4, 5 or 10). These acids are well soluble in alcohol, acetone, ether, benzene, toluene, CC14, and chloroform; in unpurified and purified state they are viscous, transparent liquids, and do not crystallize even on prolonged standing at room temperature. Their viscosity is related to the number of methyl-phenyl-siloxane groups in the molecule; it incraases with Card 1/3 $8437 Some Organosilicon Diketodicarboxylic S/079/61/031/001/021/025 Acids BOOI/BO66 the number of these groups. Composition and structure of the resultant acids were confirmed by chemical and spectroscopic analysis. Diagram I gives the infrared absorption spectrum of diketodicarboxylic acids with X 10 in the molecule. The vibration frequencies correspond to the groups - Si(450 cm- and (500 cm- Si-CH (815 cm- 1 3 S (855 Cm -1 OH(936 cm -1 ), Si-00036, 1072, 1088 cm- 1 4,FH 3 ) 2 1 COOH(1285, 1306 cm- C-0(1678, 1700 cm- ). In the cohydrolysis of compound (III) with methyl-phenyl-dichlorosilane, acids were formed with X methyl-phenyl-siloxane groups in the molecule (X = 1, 2, 3, 4, 5, or 10). They are viscous liquid products well soluble in the above solvents.

A simple method was worked out for quantitative de- t~~rmiziation of Si in organosilicon compounds (OSC). mi- neralization of analyzed substance is effected by wet pro- cedure with a iuxture of oleum or H2S04 and fuming H'103 With most OSC minQralization occurs readily, only lower al- kyl silanes (in particular tetramethyl silane) exhibit con- siderable stability. To avoid losses in the case of more Card 1/3 CZECHOSLOVAKIA/ Amlytical Chemistry - Analysis of Organic G-3 Substances Abs Jour Referat Zhur - KhimiYai No 4, 1957, 12144 volatile halogeiiated silanes,the authors recommend to weig~i the latter in cooled pyridine. Determination of Si is effected by acidiinetric method based on formation of K SiF6 in acid medium. Use is made of mixed indicator 2 In or- (methyl red and bromcresol green at a ratio 6-5). der to obviate hycholysis oZ K2SiF, at high pH values it is necessary to carry out the titrktion vith a small volu- me of liquid being titrated and in a solution saturated- with K ions. By the above-stated method the Si content was determined in several hut7dred samples of osC with ve- ry good results. VII. The authors have developed a reliable method for de- termination of halogen in OSC of the type R SiX4 n (R -- alkyl, aryl or hydrogen, X -- halogen).
