Consequently, if one could calculate the pressure for even one such low-flow operating point, this would permit a'much more exact estimate of the entire pressure characteristic than is the case at the present time. The case of zero flow rate probably corresponds to the most characteristic point of this kind, and the authors therefore investigated the mechanism of fluid motion at the input of a centrifugal wheel during zero flow. This to followed by an outline of the method for the calculation of tht pressure Card 1/2 ACCESSION APS012437 generated by the wheeL based on the model of the fluid motion. Calculated re- suits are in good agreement with experimental data published by M. 1. Nevel'son (Tsentrobezhnyye ventilyatory (Centrifugal fanq3, G03energoizdat, 1954). The "cellent agreement seems to indicate that there is no need for the introduction of an experimentally derived coefficient nor does one have to include any coef- ficients describing losses (their influence on pressure within the framework of the calculation seems to be negligible). During the operation of fans within casings, additonal factors appear which affect the pressure; however, this issue was not investigated. Orig. art. has: 18 formulas and 3 figures.

TITLE: On the classification and separation of levels in an external field PSHIODICAL: Optika i spektroskopiya, v-13, 6o.4, 1962, 580-581 TEXT: The classification of levels is based on the following property of representations of point Srpups of symmetry of the second kind (i.e. containing only one rotation): all irreducible representations of each such group G occur in pairs; the operators of the representation D(g) in each such pair coincide over 11 alaments of tho first kind (pure*rotations) g' - jgj~g' I Tnd differ in sign over-all elements of the secon kind g" = g"IS" (transfokmations which arc not ppre 1 2 rotations). .~11 characi..'r..-lof irreducible representations of points groups of the second kind can be divided into throe classes: the characters of the first two classes coincide in pairs over all pure rotations and differ in sign over elements of the second kind; characters of the third class are zero for all elements of the second kind. In the case when the group G of a symmetrical Card l/ 3 S/051/62/013/004/012/023 On the classification ... E031/E413 quantum-mochanical field is of the second kind but does not contain an inversion, a unique determination of the evenness or oddness of the levels cannot be made since the character of one and the same irreducible representation of such a group can be a positive number for one element of the second kind and negative for another equivalent alement of the second kind. However, the energy levels can still be classified by observing that the characters of the irreducible representations of the levels fall into three classes, of which the first two can be divided into conjugate pairs of lovels. The levels of the third class, corresponding to characters zero for elements of the second kind are called "neutral", being neither even nor odd. If the group of symmetries of an external field is of the second kind, not containing an inversion, even and odd levels of a free atom can ach be separated into three classes - even, odd and neutral - nd the following rule can be formulated: if some even level of : a free atom is separated in an external field into n, even, n2 odd and no neutral levels, then the same, but odd, level of the free atom in separated into n2 even, n, odd and no neutral Card 2/3 s/o5i/62/013/004/012/023 On the classification ...

Estimated and experimental noise -distribution curves (duration va. noise level) for an EPO-400 h-f tole-station are shown. An experimental noise (4Z-124 mv) vs. time (0-2000 sac) curve exhibits fast and slow noise-level variations; the noise was measured on a. carrier channel connected to a 400-kv power ACC NRt AT6012347 6 line. The noise level Is clearly correlated with the amount of power transmitted by the line. The effect of noise level on the flow of errors in the tole-channel is briefly discussed. Usually, the rate of Information transmission decreases when the noise level increases, which may result in an operational paradox., the information flow may stop (under system emergency conditions) at the moment when the information is most needed. Hance, the transmission process proper should be automatically optimized; a transmission-adaptive system matches the and-apparatus parameters with the variable traffic capacity of the channel. The adaptation efficiency can be evaluated by: (a) the decrease in the number of errors against the decreased trans- mission rate and (b) the decrease In apparatus reliability as a consequence of the, increased apparatus redundancy.

The voltage@ to be measured enter 9 multi- channel commutator, where a control block governs their successive entry in' he imput of a cathode-ray indicator (CRT) over a time v . The scanning of the T , Is synchronized with the beginning of the commutation, and its duration to seletwir to equal the commutation period of the entire ensemble of the voltages to be T.4". ured. The 3 alternative versions of We arrangement differ in the type of the com- mutator used and the method of the synchronous scanning along the axis of the abscissas: (1) An electromechanical commutator with a step-by-step switch. Card 2/7 Device for the visual observation of the .... S/777/6110001000/004/005 (Z) An electromechanical commutator with a collector. (3) An electronic commuta- tor. An experimental investigation of these 3 types of commutators denotes their respective advantages and shortcomings: Advai%tjj!*: Type (1) -simple design; permits the use of stock types of step-by-M-pswitches; type (Z) - relative freedom from noise; type (3) - total freedom from noise. Types (1) and (2) - direct voltage commutation with a transmission coefficient equal to I in all channels; type (3) - elevated commutation rate. Type (1) - commutator can be stopped at any step of the switch; type (2) - can operate with the ordinary 307 (E07) indicator; type 13) - no mechanical contacts, no rotation. Shortcomings: Type (1) - requirement for an in- dicator with prolonged image persistence; type 13) - awkward design if ordinary electron tubes are used for the commutation with a Large number of points. type& (1) and (2) - requirement for mechanical contacts and rotating parts; type (3) - need for equalization of the constants of the component gates and of the amplification according to channels to prevent a scatter of circuit and tube parameters when tubes are replaced; typo (1) - significant noise effact# during the tn~tlon of the switch. ALL three types do not permit the reading of voltages when the Letter vary with a frequency that Is close to the scanning frequency. ' Thsr~ are 6 figures.
