TITLE: An Experiment in Casting an Eight-ton Ingot With Small Height- diameter Ratio (H/D:z 0.5) F-Opyt otlivki vos'mitonno o slitka s malym otnosheniyem vy3oty k diametru (H/D = 0. 5)n PERIODICAL: V sb. : Novoye v liteyn. proiz-ve. Nr 2. Gor1kiy, Knigoizdat, 1957, pp 222-232 ABSTRACT: An experimental ingot of the 40-A type was cast. The small ratio H/D= 0.5 was dictated by the conditions of forging. In order to achieve horizontal orientation of the crystallization plane, the following steps were taken: the exterior of the mold (M) was covered with heat-insulating slag-wool, the bottom of the M was cooled by air-water jets, anri the shrinkage head wa,-, heated by an electric arc of a capacity of 1500 A. The pouring of the body of the ingot required 300 seconds, and the pouring of the shrink- age head (12 percent of the weight of the ingot) 210 seconds. The solidification time was 7 hrs. The horizontal orientation of the Card 1/2 principal crystallization plane was not achieved. A study of the 1 ~7- 1957- 1 Z -23412 An Experiment in C~aiting an'--Eight-'ten ingot, (C*Org.') longitudinal templet-. showed &:lack of axial srortG~.nes5, and a satisfactory macrostructure, with the shrinkage cavity open on top. ' LiqlLiation beyond the axial zone was observed. In the cross-sectional templets the zone of zmiall cry!-Jals occupied 20-30 mm, that of acicular crystali 50-00 mm, the remainder being non-oriented crystals of medium magnitude. On the cross - L3ectional templets taken from the center area and from the area below the sink-head, large liquation-spot~ were discovered, The heat- insulating layer around the walls of the M proved to be detrimental, since it placed the liquation zones further away from the area of the arc's action. The employment of electrical heating improved the quality of the axial portion of the ingot. Plans for the cooling of the lower section of the ingot and for the design of a mold are presented. G.

The following conclusions were drawn'. 1) in the normal dog. not more than ,56 per cent of the total chromogen in blood plasma is true creatinine, the ramaining 44 per cent consists of pseudocreatinine. 2) The renal clearance of true creatinine Is equal to the inulin clearance and can be used for-the .estimation of the glomerular filtration rate. T,.~ chromoCen clarance,on .:the other hand, is not suited for even an approximate evaluation of the G.FR in a normal dog. 3) After nephrectomy, the chromogen concentration in L31084-66 XCC Nl~ AT6022822 plasma rises concomitantly with the non-protein nitrogen. In the azotemic .animal, a consistently smaller fraction cf the total chrcinogen Is made up of pseudocreatinine and the elevation of chromogen concentration, under such conditions, is almost ntir 1 due to an increase in, the-true creatinine level...

Then the pressure head satisfies the equation 9H ~2 2 yt- m a 'a x2 where a is a constant which depends on the properties of the porous medium and the fluid. Let-the initial and boundary conditions be H(X,O) - ~(X), H(O,t) = Y(t). Then the following is proveds The functions ~(')(x), are assumed to correspond to the solution R(l)(x,t) and the functions (~ 2 (x),_qS2)(t) are to correspond to the solution 9 (2) t If then $(2) (X) it follows: X(2) (xjt);;~H()(x,t). This monotone dependence of the solution on the initial and boundary conditions is applied to prove the well-known fact that in this case the velocity of propagation of the lldisturbance~ (wave zone) is finite.
