Initially, the cumulants of the voltage distributions at the accumulator output are determined and the connection between the cumulants of the nth order at the output and at the input of the accumulator is established. Knowledge of the cumulants of any order of the output Card 2/5 25815 Distribution of random voltages s/l42/60/003/oo6/oo5/ol6 E033/E135 voltage enables the distribution law of this voltage to be obtained to any desired degree of accuracy. This law can be presented either in the form of an Edgworth series or in the form of a system of Laguerre orthogonal functions. The Edgworth series has been examined in previous literatiftre (Ref.St G. Kramer, Matematicheakiye metody statiatiki, lzd-vo in. lit-ry, 1948) and (Ref.6: B.P. Levin, Izd-vo Sovetskoye radio, 1958), and therefore only the Laguerre system is considered in this article. The coefficients of both series are expressed by the cumulants of the output voltage distribution. The Edgworth series are suitable in the case where the investigated process approximates to the normal, e.g. the voltage at the output of a non-coherent accumulator consisting of a linear detector and an accumulator having an exponential weighting function corresponding to m = 0.8-0-95, the input voltage being a train of a large number of pulsed signals Accompanied by noise. With square-law detection and an accumulator (m = 0.8-0.95) the distribution law of the output voltage differs significantly from normal, and it is then more convenient to use the Laguerre orthogonal system.

PERIODICALs Izventiya vysshIkh uchebnykh zavedeniy, Radiotekhnika, 1961, Vol.4, No-2, PP-148-154 TEM The aim of this article in to determine approximately the threshold signal/noise ratio detectable by a non-coherent accumulator with an exponential weighting function (EWY). Such apparatus comprises a non-coherent (amplitude-) detector followed' by an Integrator with a: de-layed'feedback loop, the factor m of which is less than unity. The threshold signals of square-law And linear accumulators with EWF for rectangular pulse-signal trains.accompan:Led'by Gaussian noise are determined-. Ther threshold signal/noise ratios of coherent and non-coherent- accumulators with ZWF are compared and the gain due to an Integrator with EWF after a non-coherent detector calculated. Approximate expressions are obtained*for the probability D- of correct observation (PCO) and for the Probability F of false alarm (PFA) for square-law and linear accumulators with EWF.

However, when a coherent accumulator with EWF is replaced by a non-coherent accumulator with EWF; then a.power gain of the order of 2 to 2-5 is obtained- (D -0.9). For relatively long pulse~tredhs and when 10-4# the power gain due to using an accumulator with ZWF after a.linear detector equals 4.6 for m w-0.8, 7.5 for m w-0.9 and 11.4 for m =70.95..

Eq.(3) can therefore be integrated by the method of' slowly varying quantities. It is found that the accumulated noise, power Is proportional to the input noise Intensity and the filter passband. The noise power for an ideal lowpass filter is given by' the expression 2 m The author then proceeds to consider noise accumulation for a systemeonsIsting of two or three series-connected delayed-feedback- devices. It is found that the noise accumulation factor increases sharply as the feedback factor approaches unity and with m =-0.9 reaches 291 for two series-connected devices and 142600 :eor three. devices. This results from the fact that at the output of the f3.rst comb filter the remaining noise is already strongly correlated. There are 3 figures and 7 references: 6 Soviet and I non-Soviet. Card 2/3.

The band-pass width is also exa- mined. An optimum filter for a square wave of N square shaped pul- ses applied together with white Gaussian Noise, consists of an op- timum filter for a single pulse signal, a summing system with a feedback circuit delaying for a 6ime T equal to the repetition rate of the pulsesy an assembly delaying for a time NT, and a read-out system. An integrated pulse of lengths T enters the optimum filter and a saw-tooth pulse appears at the output of twice the length and of amplitude U T where U is the amplitude of the in-going pulses, 1 1 Card 1/2 34027 S/109/62/007/001/004/027 On the efficiency of a system of D273/D301 The wave-train of these saw-tooth pulses is applied to the input of the summing system where the amplitude is increased N times. This potential is applied to the input of the read-out system and the output potential is a wave-train of pulses, the maximum value of which coincides with the termination of the wave-train at the in- put. The optimum filter for the single pulse can be replaced by a simpler RC-filter of lower frequency C51 with transfer function (W) = 1 - + JW 2 -jr 6 F1 where A F1 Is its band-pass. An attenuator with a transfer coeffi- cient m has to be included in the circuit in order to prevent self- oscillation of the summing system and it is shown how a practical approximation to an optimum filter is a combination of a frequency filterp a summing system and a feedback circuit with a delay time T9 an attenuator of coefficient m and a filter 0 [Abstractor's note: This should probably read 021.

B117/41e6 towards a stronger field. ihia shows that in the latter case the hydrogen bond-between the phenol molecules is weaker. The importance of steric screening (volume of ortho-substituents) for cyclic association, in which mainly tetramers and only small amounts of dimers are formed, was studied in some alkylphenola dissolved in C01 4# When the number of ortho-sub- stituents is increased, the band of the bound hydroxyl is shifted to higher* frequencies and the shift from the H bond AT becomes smaller, probably due, to its.effective elongation. Owing to the weakening of the hydrogen bond the inhibiting activity decreases in the following orderz .2,6-dimethyl-, 2,6-diisopropyl and 2,6-di-tort-butylphenyl, and a further growth of the C6-0 8 radioals-is prevented. In di-ortho-alkylphenolop.disi3olved in CC1 4 at low concentrations the chemical shift of i on a horizontal section is dependent on the concentration. When the number of ortho-substituents is increased the "saturation" of this dependence takes place in the region of higher concentrations. In 2,6-di-tert-butylphenol and ionone, the shift of the hydroxyl is independent of the concentration.

Cold rolling of IKhl5N9S3BIsteel tubes presents serious difficulties owing to'the formation of large, a_1~0_-U_n_ts_T0-70%) of martensite. This martensite appears to be the only cause of difficulties since it has been proved experimentally that the steel in fully austenitic condition is not age-hardenable. Tensile tests at 20 to 500C showed that:deformation at temperatures below 150C promotes martensitic trians formation. The maximum amount of martensite (40-57%) forms with deformation at 20C. Additional annealing at 850C (after annealinf at 11000 intensifies the martensite formation. . Annealing of cold-ro3_led_kv_bMr'at 450-700C brings about a reversed alpba-to-gamma. transformation, but in following cold working, the austenite transforms back into martensite. Examination of a tube section taken from a stopped 4ttird 1/2 uDc: 62o.18,669.14.018.8 10891-66 Ap6oo&607 cold-rolling mill showed that as.the reduction increases from 0 to 38%, the amount of martensite increases from 0.3,to~ 38% and the hardness, from 235 to 388 H At this point,~ -*ap'p" iren~l and no more the temperature of the metal becomes higher than 150C. viartensit is-- formed with a furth& increase in reduction' to 45%. On the basis of the above experiments., "warid' rollinglIs recommended for lKhl5N9S8B steel tubes; either the tubes should be. ~preheated to 300-350C. before entering the cold-rolli.ng mill, or the mill rolls should be preheated. The rolling should be.. done without a coolant. Orig. art. has: .4 figures.

TITLE: Effect of structure of various polyphenols on the properties of epoxy resins PERIODICAL: Plaste und Kautechuk, v. 8, no- 4, 1961, 171-174 TEXT: The effect of structure of the phenolic component on the properties of epoxy resins of medium molecular weight was studied. Preparation of the phenolic component: The bisphenols (2)-(9) in Table 1 were prepared by con- densation of the corresponding ketone and aldehyde, respectively, with phenol or o-cresol at a molar ratio 1:1.78 in the presence of 72.5% H 2s04 and a small amount of toluene and thioglycolic acid at 40 C; (12) by melting 62 g of 2-methyl-4-tert-butyl-6-methylol phenol with 105 g 8f 2-methyl-4-tert- butyl phenol, addition of 5 g of HCl concentrate at 90 C, heating to'120 0C for one hour, distilling off in vacuum of the nonreacted 2-methyl-4-tert- butyl phenol, rinsing of the residue with petroleum either, and recrystalliz- ing from gasoline; (13) by melting 42 9 of 4-tert-butyl-2,6-dimethyl phenol with 280 9 of 4-tert-butyl phenol, addition of 7 ml of HCl concentrate, slow Card 1/8 G~004/61/008/004/001/003 Effect of structure ... tj 20/B206 solidifying under stirring and cooling, distilling off the nonreacted 4-tert- butyl phenol through water vapor distillation, and double recrystallizing of the residue from ethanol. Preparation of epoxy resins: To a mixture of 1 mole of bisphenoll 1.33 moles of epichlorohydrin and dioxane (30~6, related to bisphenol)t 1-40 moles of NaOH (in 3q- solution) was added dropwise at 700C in the course of 2 hr, then kept for 2 hr at 75 0C, and then the mixture butanol - xylene (113) was added in the same proportion by weight as the original bisphenol. In the bisphenols (2) and (11) (see Table 1) dioxane had to be used as solvent, in (1) the part insoluble in butanol - xylene was dissolved by addition of dioxane. Two layers formed which were separated, the resin solution was cooled, neutralized with C02, dehydrated by azeotro* distillation,filteredt and the solvent was finally removed at 1700C in vacuum. The resins from bisphenole (6) and (10) were dried by means of silica gel. Properties of epoxy resins as dependent on the structure of the phenolic component: see Table 2. Explanations: Column 9t the cementing was hardened at 180-C for 2 hr, and the properties were rated according to Lidarik, M., Plaste und Kautachuk, V- 7 (1960), P- 55- Column 12: test of the produced epoxy resins for their suitability as Btoving lac uers, These were produced according to Swiss patent 257115 of the Ciba AG Nugust 30, Card 2/8 G10041611008100410011003 Effect of structure ...

Stoving lacquers made from the very easily accessible 2,2-bis(4- hydroxy-3-methyl-phenyl)-propane of good yield show unsatisfactory properties, even after combination with a resin from dimerized fatty acids and tri- ethylene amine. Casting resins from 2,2-bis(4-hydroxY-3-methyl-phenyl)- propane, hardened with -~hthalic anhydride, show insufficient strength properties as compared with those from 2,2-bis(4-hydroxy-phenyl)-propane (the values of resins made from 2,2-bis(4-hydroxy-phenyl propane are in arentheses): tensile strength 147 (460-510) kg/cm~, flexural strength 541 700-810) k~/=21 impact flexural strength 5 (16-24) 0kg/CM2; the resistance ~ to heat according to Vicat is about equal: 116(115) C; the electric insula- tion properties are inferior: dielectric constant 4-58(3.66), loss factor at 800 cycles, 0.069(0.0011), resistivity jo15(j016jS?-cm. Table 3 shows thE measured values for the deformation test according to H6ppler after hardening the resins with phthalic anhydride (one molecule fog 2 epoxy groups). Prepa- ration of test pieces: the resin was heated to 120 C, the phthalic anhydride was stirred in for 10-15 min, the mass was then poured into the mold, and the test pieces (cylinder: 11.5 cm diameter, 8 cm height) were dried at 1200C for 17 hr. Conclusions: The epoxy resin properties strongly depend on the stvacture of the initial polyphenols. 2,2-bis(4-hydroxy-phenyl)-propane producc.es resins of universal applicability. Resins of special properties Card 3/8 G/004/61/008/004/001/00,A Effect of structure B120/B206 can be produced by using other polyphenols.

TITIE: The influence of accumijlAtov parameters on their operating efficiency PERIODICAL: Radiotekhnika i elektronika, Vol.61 No*49 1961, pp. 529-535 TEXT., The author continues his investigation of comb filters (see Ref.2t Radiotekhnika i elektronika, 1961, Vol.6, No.2, 187). The effectiveness of such accumulators can be judged on the basis of the improvement in signal/noise ratio. The comb filters are characterized by the author by the following two parameterst bandwidth &F and feedback factor m. The improvement in signal/ noise ratio as a function of these parameters is calculated for rectangular pulses in normal white noise. it is found that optimal values for the filter parameters exist. The optijual value of bandwidth increases sharply as the feedback factor approaches unity, and is not very critical for a single accumulator. Compared with an optimal.filter, a comb filter with m = 0.9 gives gains of 3.5, 9.56 and 12.5 for one, two and three accumulators in series, Card 1/2 22890 S/109/61/006/oo4/004/025 E140/E163 The influence of accumulator parameters on their operating efficiency respectively. while the use of the second accumulator gives an improvement of a factor of 2.5, a third accumulator gives only an additional 30%. The author therefore concludes that in view of other complicatIng considerations, two filters in series are useful, but not three. There are 7 figures and 4 references: 3 Soviet and I English.

C. Go Stuckelberg and Go Wanders (Hely. Pbys. Acts. v. 2T, 667, 1954) on the incompatibility of macrocausality, which consists in the requirement that the interaction aver macroscopic time inter-' Yale be mediated by quanta with positive energy, with unitarity in nonlocal field theory is due to an unfavorable choice of the anti-bermitian part of the vertex graph. It, is shown by transforming the appropriate integral that the macrocausality conditior is actually satisfied formal3y in a vhole class of nonlocal theories for which the re- duction formula of:Lehmann, Symmik, and Zimermann is applicable.
