The saliva discharge was provoked by powdered neat bisquits being eaten, or by an oral induction of lemon citrate.

Hypotheses of Nakbmonzon on the role of acetylcholino in Itransmission of nerve impulses and of Kelly on the presynapt-';-c action of $primary acetylcholine and the postsynaptic action of secondary ;acetylcboline are discussed. Possible importance of acetylcholine as a hormone in nerve deprived tissues is considered. Date are presented on .the characteristics of acetylcholine effects on the central nervous :system with different routes of administration, and the effect of acetylcholine on the reticular formation. Works are cited showing the i Card 1/9 UDC: 615-785-4 L 4bIC--i--66 ACC NR:AR6 oo8635 deperidence of the acetylcholine level of the brain on its activity leveL. Syntheses and breakdown of acetylcholine in the tissues are examined. .The properties of cholinesterase, its level in various organs and .tissues, and activity change in the process of ontbogenesis are described. A classification of cholinesterase inhibitors (according to Ammon) is Eiven. The relation of certain pathological states (allergy, inflammation and others) to acetylcholine metabolism is discussed. Data'! are presented on change of cholinesterese activity and acetylcholine .concentration in tissues and body fluids during some diseases of the central nervous system, liver, infectious diseases, radiation injury :2nd others. High efficacy of cholinesterase inhibitors during certain ~di,-ease3 is shown, and the need for long range studies of acetylcholine metabolism and factors affectin it is emphasized.

The interference-ii;muniity of transirdttinE; telemetering signals is determined for amplitude, frequency, pulse-frequency, uridth and code modulation with weak and relatively strong fluctuatine interference. The magnitude of the reduced mean- square error is used as the criterion to estixiate the interference-immunity. The error .Cor weak fluctuating interference in a com-unication channel is deterrined by T-he method explained in a V. A. Kotelf nikov work. It is shown that optimum transirdssion parameters eydst for FN, F:1141, and FGii wUch quarantee a rdnimum value of the reduced mean-square error for a given inter*L'erence level in the comeTiurdcation channel. A comii;arison is made of these kinds of :-no-dulation for op-tiiaun and nonoptimum transmission parameters. 03 J- code i-ty TIT__f ~.Odo' Ci-i i v0sti Vn 3 2b u th Tee 'c.~,' '3. u - T ar Dr -1 _j_,ja_Is bi a-rY cOaO C'CC di _01-e. ue S - 1 0 C_ code, (2) t'! a iren" ly b:Li ary -ftd- a!7-' ass nt -.11', ~'isxial 0 '- 4- Cl Co~_C 15 S U- code 4 -he -)Ssio' the a it _e cocl_ , TO to I I 'j c-llrl: -t-~_jice an c, of er3:01 rres~~Tlcl- 'R__ I) is Ol t U_L. ..-o u 7 e s ame :aessa-e T; - ti-le . , t, thall S 3- i:1 an d. 10' ,b Of e S u t1a. 0 il 2. t e r t1le ET. t - )J ar b-- ty re lor r~. 1 /4 Cc N J. r If bi-n-ary (,Ii-- robabi Lity of d JL 3 ~v- o rt- i -) aof the oir-al (c -D f 1:~ ) ai,(: lcrivod. a.

Moscow, Izd-vo AN SSSR, !961, 368 - 383 TEXT: The authors present the results of their lnvesiigatJon at the Institut avtomatiki i telemekhaniki AN SSSR (Instoituote~Lof Auto- mation and Teiemechanics, AS USSR), of the interference-killins properties of telemetering systems in the presence of weak. compa- rat-41-vely strong and strong fluctuation and inpulse interference. In general, without specific limitations, good interference-killing properties may be obt-ained with d'ifferent methods of telemetering, In most cases of actual industrial telemetering systems and in *ransistorized radio-telemetry systems, -the signai is 4rited In Card 1/-i 32589 S//569/61/0n,3/000/UC8/0;1 interference-ki'Iling properties D201/D305 amplitude. The auihors show that, as opposed to the earlier assump- tion,the best interference-killing properties are exhibited by cooled binary teiemetering systems, the maximum interference-kili- ing properties are actually shown by frequency systems of teleme- terming, for a wide range of changes of parameters and interference level. Such a Performance could not be obtained with coded teleme- tering systems without considerable technical complications, As the most suitable method of noise analysis in telemetering systems, a simple photographic method of determining the probability density of amplizude is suggested. I-t consists of taking photographs of the random process displayed on the screen of a CRO with subsequent analysis of the film by means of a micro-photometer~ This method was found to be suitable for analyzing fluctuazing processes at frequencies from 1 Kc/s upwards, using standard after-glow tubes (hall-glow time 10-2 ~. ~ I. u 10-3 sec).

The signal of the control command 'connect' or 'disconnect' is transmitted, after addressing, by means of any ex- i'stin;y method. In comparison with a multichannel system, a coded selection transmission may be used for statistical coding in sys- tems controlling several objects. The speed of operation is the same, and the efficiency and the interference-killing properties are much better. For a given delay probability and statistics of information, the maximum number of objects which can be serviced ,--may be determined by a single system of address transmission.

Ex 'pediez-uy of using either of the above methods can be determined from the "average-loss criterion" which is defined in the article. The methods (a) and (b) result in practically the same amount of losses when the average interval between two consecutive info sendings is much shorter than the repair time. The method (c) cuts the losses, as compared to the method (a), if the repair time is less than the average interval between sendings multiplied by 5. Orig. art. has: 3 figures and 8 formulas.

It is found that: (1) In telemeters with an error of I - 10%, the best noise immunity can be achieved with an optimum FM; time division of channels may be recommended for multichannel systems; (2) In telemeters with.an erro.- tmder 15a, code methods are expedient. the code methods ensure a high noise immunity but require a rather broad 'frequency band; binary all-combination codes provide the beat efficiency; (3) In high-accuracy systems, wherever an excess frequency band is available, a high noise immunity can be attained by using high-energy codes; (4) The high-energy codes cover m any-frequency, codes in systems with a limited signal amplitude and; f also C:' codes (m. >> n) in systems with a limited mean power.

An illustration shows this device. It consists of a cast-iron case mounted on the slotting machine in which in a dovetail-guide a steel ruler moves with a rigid- ly fixed model rack (modulus and lenGth correspond to that to be worked). On the slotting-machirie spindle on the thorn a cog- wheel is moubted which is coupled with the model rack. The ad- justment of the slottin,-, machine is carried out in dependence on the number of teeth of the cogveheel. The workpiece is fixed to the ruler by means of the castin.-s. Slotting is carried out by means of a tappet in one stroke all through. For the passage of the ruler a rectangular opening is provided in the supporting fraine of the slotting machine.
