The switching is performed by germanium alloy transistors. The basic circuit of the device is: T2 'Q I3-c~a- I -E "~- 0 (:b) (a) (b) (c) r~ inDU Y ~)ut outp ~t ,16jr Card 1/2 L 4C)C)66-60' ACC NR1 AT6019742 When transistor T, or T2 or T3 is conducted (while the others are cut off) the output voltage will be connected to the output from point a or b or c of the step attenuator. The conduction of the transistors is controlled by the base current through resistors I R. To obtain better switching, an additional transistorized device is added to each stage to provide minimal inpum base resistance R (when the transistor is cut off) and maximal R during conduction. The attenuator is controlled by logical circuits working between levels of -10v to tl0v, and 0 to +20v. The maximum error of the output volt- age-at frequencies between 100 kc and 20 Mc was 15%.

The Congress was attended by 1,240 scientists, engi.neers and specialists, employed at 300 scientific-research organizations and vuzes, scientific- technical societies of the electric power industry, mining industry and water transport, and 35 specialists from Albania, Bulgaria, Hungary, East Germany, China, Mongolia, Poland, Rumaniag Czechoslovakia and Yugoslavia. The Congress examined the conditions and prospects for research into the hydrology continents, and pointed out the great achievements accomplished in the field of hydrology and water resources of the USSR. A number of reports was heard by the Congress, among which may be mentioned the report of Candidate of Technical Scien- ces V~A- Uryvayev (State Hydrological Institute) "The Study Card 1/4 of the USSR Continental Waters and Further Tasks in This The Third All-Union Hydroloffical Congress SOV-98-58-2-18/21 Field", The Doctors of Technical Sciences 3,N, Kdtskiy and M.F.

Professor A.N. Voznesenskiy (Institute "Energoproyekt-') spoke on "The Utilization of the USSR Water Resources and the Pro- spects for Developing 'Nater Power". A total of 9 special- ized sections were working at the Congress: Calculations and Prognoses (Chairmen - Doctor of Technical Sciences, Pro- fe3sor DcL.

Over 400 report3 or, a1L principal problems of the hydroio6, cf co.,- tinents were deli-rered and discussed at the sections. The author lists the work performed during the 40 years of Soviet regime and speaks of current needs., The Congress adopted several decisions, approving the resolutions of the sections, and considered it necessary to establish an inter-depart- mental committee to co-ordinate scientific research work. The Congress decided to take necessary measures for an urgent exploitation of the State Hydrological Institute's River-Bed Laboratory, whose activity should further the solving of im- portant scientific problems in the field of hydrodynamics Card 3/4 and river-bed processes.

The following paradox arises from calculations made at home and abroad (Ref. 2)t in the range of rarely reoccurring maxima, the probability curve drawn after the rain course is higher than the curve of the highest maxima during the year (maxima due to snow malts or rainfalls, respectively). This paradoxical situation is explained here, and a calculation procedure satisfying the nature of objective phenomena is shown. When setting up the curves, the parameters of the three curves (of water amounts caused by snow melts, such caused by rainfalls, and the curve of the yearly maximum amounts) are estimated on the basis of data available. The third parameter, the coefficient of Card 1/3 On the Estimation of the Probabilities of S/050/60/000/05/08/020 Excess Maximum Water Deliveries in Rivers Fed B007/BO14 by High Waters of Different Origins asymmetry, however, is assumed on the strength of general considerations. Its values are assumed for the common curve and do not correspond to the distribution laws of each individual high water type. This gives rise to the mentioned discordance which can be eliminated by a proper selection of the coefficient of asymmetry. The correct procedure is illustrated by the diagram in Fig. 1. This diagram contains the probability curves for each of the high water types. It is assumed in this connection that there be no-statistic relation between the two high water types observed during the same year. The formula from paper (Ref. 1) is written downs It is possible by this formula to set up a curve of the yearly maxima, based on the given probability curves of the maximum water deliveries of each of the high water types. In the upper part of the diagram, this curve forms, so to speak, an envelope for the curves of the two high water types. In the range of low probabilities of an excess in the maximum water deliveries it practically coincides with the curve giving the higher values of the very rare peaks. Usually, the rain maxima fluctuate loss, from one year to another, than is the case with the snow maxima. Therefore, the upper branch of the common probability curve approaches the Card 2/3 On the Estimation of the Probabilities of 5/050/60/000/05/08/020 Excess Maximum Water Deliveries in Rivers Fed B007/BO14 by High Waters of Different Origins corresponding branch of the rain-peak curve. For an illustration of the foregoing, the example shown in the Fig. is given in all details. There are I figureq 1 table, and 2 references, 1 of which is Soviet.

The whole is boiled to a complete dissolution of the specimen. 100 cc H20 and 40 cc NH40H are added, and the solution is diluted up to the mark. The first portion of the filtrate is discarded, the second is investigated on an FEK-M photoelectric colorimeter with a red light filter in a 20-cc cell, The calibration curve is drawn with the aid of specimens of Al alloys with known Cu contents, K.

The direction of the current was reversed by means of a throw-switch; the swit6hing frequency was controlled with a stop watch. Before plating, the steel specimens were cleaned with emery paper followed by boiling in alkali and dipping in HCL solution. The current efficiency of the plating process was determined by the use of a copper coulo- meter.
