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.

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 , 2 2' 0-13%Fe2 03" 0.60%Cao) with a specific surface of 30-,~ m Ig was used, and annealed at 550 0C for- two hours before the experiment. Tne experiments were Card 1/3 Exohange Capacity of' Alumosiliuate S/076J60/034/010/00T/022 Cracking Catalystv B0151B064 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 Card 2/3 ~L 140546 :ACC Mi AF6008352': SMCE CODE: HU/0036/65)'072/005/0305/0319 AUTH(R99 01 _(co reisponang member NTAq DJxector) tpml - y MG: Re qqLpl mff$ un of Sciences.6 search Grov 5,_ _%glar _VLAcadow magyar TudowWon Almdamia FoldrajstudomaMd Kutatocic AjaT TITLISa Current pmblems of thet genpaphi~g. sciences SOURCE: NLgyar tiklowxyl, v. 7,,!# no 5v 1965p,305-319 TOPIC TAGst ograiphy,, gemorphologyt cartographyp economic pographyp ge demography3, agric%CLtwle A Seneral ;made o! the subjects Covered by, the desilr", AMFLkCT:: worway Was, apgrapbleal rossaimbAn ftestr7g, poSra- raw phical. research VrDjegtg.of & general nature., geowrpbological eartog pby.% research an the spatial distrLbution of the facilities of the lbaga- x1an *c0nqAyp Usps for agricultural investigations am for �01.1 Utilize- twastrial-Sw*rafts dewp&phical goograpbys,'ths Mattimal Hunts- mlatlau' betweas N4r4arLan Swaraphical "60019b , OrPutla- forsits "J. x!~~texa of abdulatira kol EJPRS1 SUB.:doMl 08 MH DA79: none OUG RIFt OD3 SM MTS 001 Aikr4 2A .Ipf)cs4 , Marton' bela[Sarfalvi, Deli); .1; SIj-dtFALVI, S.I.,, red. ; ZALBIROV, B.Sh., red.; SILUIOVAIJ)VA, U.S. mladshiy red.; KRILINA, Z.A., red. kart,; 13TRIAKA, W.F., tekhn. red.

Darivativea of Primary Aromatic Amines (I. Proizvodnyye pervichnykh aronaticheskikh aminoy) PERIODICAL: Zhurnal obshchey khimii, 1950, Vol. 20, Nr 6 , pp. 16771 - 1601 (USSR) 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 Monoanils of Glutaconedialdehyde. I. Derivatives of SOV/79-28-6-54/63 Primary Aromatic Amines 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.

TITLE: On the Structure and the Reinforcing Action of Colloidal Silicic Acid as Filler of Synthetic Rubber ( 0 strukture i usilivayushchem deystvii kolloidnoy kremnekisloty kak napol- nitelya sinteticheskogo kauchuka) PERIODICAL: Doklady Akademii nauk SSSR, '1958, Vol. 119, Nr 6, PP- 1170 - 1173 (USSR) 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 Card 1/3 series of samples of colloidal silicic acid with high,mean,and low On the Structure and the Reinforcing Action of 2o.-119-6-33/56 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. On the Structure and the Reinforcing Action of 2o-119-6-33/56 Colloidal Silicic Acid as Filler of Synthetic Rubber The activity of the colloidal silicic acid can be decreased considerably by heating at 6oooC.
