A block diagram of an automatic phase frequency trimm- ing circuit with reduced phase.instability is shown in Pig 1. For reducing t-he phase instability, the fre- quency deiuning of a free self-oscillator (jog in re- gard to the frequency.of an external. force, is compen- sated by trimming with a frequency detect-or.

The calculation Is based. an the involvement of methods of operational computationq~, the theory of filters, and the similarity of the theory of filters to the theory of long lines. The voltage on the active load is'presented in the form of an electric- series containing analogs of incident and reflected waves while the waves. reflected from the load, are not taken Into conrjideration. rhe effect of the number of links of the artificial line on the pulse shape is indicated. Experimental oscillograms of pulses are in.kood agree- 1/2 UDC: 621.376.5 of SMBRYAKOV, Yu.0 gvardii inihener-podpolkovnik; YEVTYMMII, 1, POdPolkovnlk. inzhoner- For an efficient operation of automobiles.

The study reported was mainly devoted 'to the investigation of the lubricating properties ofhigh and medium concentration suspensions and pastes-, as littla attentiorL has been &Ivan to their study in spite of their wide-spread use. Rheological properties (tha so-called strength limit). colloidal *stability, antivear effec .6 t coefficient of friction and t 'he longevityJo4 films were determined. It L M was found that pastes and suspensions, which can be prepared with MoS 2 and a surfactant in a nonstructured or structured modification (the Card 62i.893 ACC M AP7002727 lattar having a three-dimensional solid phase network.structure), do not"* ;differ significantly in their coefficients of friction a~d longevity of ~:films. (Structuring is achieved by introducing a surfactaat, i.e., a soap, usually lithium Atearate on heating, when soaps.swell in the ambient oil and produce the three-dimensional network). The high a trength ;limit, especially in structured suspensions, is detrimental for theanti- wear efZect because of's decrease In the mobility of the lubricant. The colloidal stability. determiiLqd by centrifuging 'Increases- with. the cou-t_ Idantration of'HoS2 ana the viscosity of the.sv'steim. The structural activity of soaps Is stronger In low concentration suspensions than In !highly concentrated ones. The addition of MoSa increases the antiwear effect of lubricating oils, e.g., the introduction of this solid lubri-- cant into UIATLIK-221 grease increases thelongavity of its films by 10-12 tizaa under a $600 kg/cm2 load.

Cast,cutting tools PIMIODICAL.- Litaynoye proizvodotvo,, no. 3, 1962, 38 39 LIECT: The authors describe the technoloa of manufacturing cast cutting ti)ols, f rom the hif~i-specd steel gradles P 9 (R9) and P 18 (R18) modified with bovoil. Tho burning out of carbon during the smelting process was compensated for by the addition of - O.',~*, and 0. 1%1 C for the gradon R18 and R9 rospectively, in the form of. R18 steel carburized up to 5%. The addition of thiu alloy, without re ducing the basic quantity of alloying elements, considerably increases the C- ccntent of the melt. The steel was reduced with 0.2% Al, then O.OIOPC" boron was added 70 - 90 seconds prior to casting at a constant temperature of 1,1150 - L-~ 1,1180'3C into the molda. The authora give a description of the used chills and casting technology,according to which cutting-off, profiling and ollazing tools were manufactured, the steel grades having ~the following composition. 0.66 - I - 1% C; 7.8 - 9 - 1% W; 3.0 - 4.0% Cr; 2.0 - 2.Z V; 0.001,"S B, and 0.8 - 1. 1% C; I T.6 - 18.5% W; 3,.7 - 4.9,L"o' Cr; 0,92 1.2% V; 0.001% B. The heat treatment Card 1/2 - S/128/62/000/003/004/007 Cast cutting tools A004,/AI27 consisted of double tempering for I hour each at 600 6200C. The following parameters were obtained: MG 63 - 64, 6b = 80 95 Ic&/mm2, ak - 0.2 1.0 kgm , /cm ~ The tools were tested on automatic turret lathes. The tests showed that the life of cast tools exceeds that.of forged "U'ools b,,,, a factor of 1.15 viith radial feed and by a factor of 2.4 with tangential feed. The life of cast cut-off tools ex- Qeeds that of forged tools of the same type by a factor of 1.6. The authors point out that the life of cast tools can be compared with sintered carbide tools.
