Oxygen supply into the upper tuydres and paxti- cularly into the third row of tuy~res increases the temppratuxe of the flue gases and increases the heat loss. It is recommended to supply oxygen into the lower row of tuye'res of cupolas with a recciver and iyito the second row of tuyeres of cupolas without receiver.

The method of upsetting pipes both in a calibrated ring and "dth- out dies was submitted in 1955, and is under development at the NIIPTMASh (Krama- torsk). The NIIPTMASh in conjunction with ITM have tested 299 x 12, 299 x 14) and 180 x: 12 mm dimension pipes for excavators for 'which grade 20 or X steel ulth no more than 0.12% C, 1.3-1.7% Mn, 0.3-0.6% Si, 0.15-0.4% Cu, 0.01-0.03% Ti, 0.3% Gr and Ni, 0.045% S and 0.04% P, were used. The device, mounted on a lathe frame, comprised: a working tool, a wedged mechanism with hydraulic driviD for clanpIng down the upset pipes, a hydraulic drive for feedinj;,t the pipoij and a device for thei coordination of pipe and inductor feed. It is stated that (I the mechaniaal 'Oro_ _ perties and fiber texture in the upset metal did not differ fTom the initial metal; (2) the metal ain microstructure couia be iontrolled by the temp4irature of up- setting and (3fit was possible to upset pipes with a 2-3 fold wall thickening in a single operation by a continuous step-by-step method.

TITLE: On the drop of deformation resistance of metal wheti fox%,Iaig large ingots FERIODICAL: Referativnyy zhurnal, Mashinostroyaniye, no. 15, 1962,.J', abstract 15V13 (In collection: "Konstruir. i telchnol. mashinostr.it. Moscow-Kiyev, Mashgiz, no. 1, 1961, 203 - 207) TECT: When forging blanks out of large Ingots, a drop of the deformation resistance taken place as the degree of deformation increases. So when sinking a 125 t 40H (40N) steel blank the deformation resistance decroaaes J.n the pro- cess of sinking from 2.52 kg/mM2 at the first prossing to 1.28 ~.-IVM64~ lkt the last one. The deformation resistance of a metal in affeated by the temperature, degree and rate of deformation. When forging large blanks the inner'temperature practically does not change. -The conversicn of a part of mechanical emergy into thermal energy of the forging contributes to this phenomenon. Por tblis reason tfie main bulk of metal, with the exception of surface layers, has a coastant Card 1/2 sl i 2a/6 Wocolo 15/o 11/0 13 On the drop of deformation resistance of... AO5P_/A101 temperature. As in the process of forging the degree of defordation increases the deformation resistance can decrease due to the crushing of thecast dendrIte' structure; this crushing facilitates the softening processes. An increase of external friction farees with. the,4noreaso of the degree of detlormation has aaL insignificant effect on large'forgings, since because of their large dimensions the relation of the contact surface to the volume is rather loir as compared with small blanks. The rate of deformation when sinking heavy ingol;s decreases con- siderably in the course of one pressing and also from pressing to pressing, par- ticularly when the pread iz !qcrking at tha limit of its capacity which is the case at last pressings. At the same time the rate of deformatl.Qn drops from its maximum value to zero. Oiuch a sharp decrease of the rate results in a consider- able decrease of the deformation resistance of the metal of tho blank. A very considerable decrease of the deformation resistance at the end of a pressing, when the speed of the crosshead approaches zero, takes place also as a result of' the strain relaxation, that is if the transition of a part of clastio deforma-. tion Into plastic onej because o' this transition, the forglx4l recoWas iome deformation at a considerably lower C"Rforriation resistance.

TITLE., Distribution of the number of counts oi' a n(tubron dete6tor'~ placed in a reactor PERIODICAL.- Atomnaya energiya, v. 10, no. 4, 1961, 379-381 TEM The distribution of the number of counts of a-neutj".on deteotoi placed in a stationary sub-critical reactor deviates from Folgeon's law on account of the occurrence of reaction chains. In each interval of time, the mean number of counts depends on that of the prs(~eding interval and is unevenly distributed. It may be assumed in this case throt the actual distribution of the number of records can be described by a negative binomial distribution whose generating function is gi-ven by 2 (Z) ' Po +Piz +P2z + 11 --Y (Z - 1)3 I dk z where Pk -71 k is the probability of k counts ina given int erval, dz LO Card 1/6 S/089/61/0 10/004/013/027 Distribution of....

In order to verIfy experimentally', the pulses of an CHM-5 (SNU-5) proportional. counter placed,in a reactor were recorded on the film of a loop oscilloscope together with time markings and subsequently counted visually. The %2 crite.1-jan was applied to the results of two experiments and two a9lectiona each. For three selections, the agreement between the experimental restilts and the distribu- tion law (1) was found to be good, whereas a deviation ocetirrod in 26 (of.

The errcws of such parameters were estimated by conventional methods of mathematical statistics on the followine 6ssumptions: (a) the quantities Xi(i - 1,21 .. m), which are used to determine tho unknown parameters a and P, are independent random quantitioi following a woll- known dispersion law with the mean values Xi(alp); (b) the relative errors of a and P are small. The errors of the neutron resonance parameterd in the total cross section, determined from experimental. data on the passage of neutrons, are analyzed. The.parameters obtained with instruments of high resolution are analyzed by the method of least equareng while the method of areas is used for those obtained with poorly resolving inbtrumonta (of. D.
