Pulse frequency ros@ significantly, ''2 !during mild physical exertions and changes in the position'of the body. @There was an increase in intraventricular conductivity, " Increase in ;the systolic index (7-1176), and a delay in restoration of hemodynamic indices after physical exercise.

Vital capacity of the lungs diminished by 8-1216, while pulmonary ventilation increased by 151-18%. 'Neurological examinations revealed a light tremor of. the fingers a high orthostatic reflex with an absence of pulse reaction to the oculo-, cardiac reflex, and an increase in the slow bioelectrical activity of the brain cortex. , Psychological tests revealed an increase in distribution and in the middle magnitudes of the duration of the period of sensory motor reaction.

Approx@anate method for analysis and calculation of.principal characteristics of the amplitron SOURCE: Vsesolruznaya nauchnaya sesslya, posvyashehennaya Dnyu radio. 22d, 1966, Sektsiya elektronikis Doklady. Moscow, 1966, 10-19 TOPIC TAGS: waplitron, platinotron, SHP amplifier ABSTRACT: Mutinct from the well-known G. Dombrowskiy method (Trans IRE, 1959, ED-6I no. 4, 419), a new method is suggested which uses the averaging of S11F potential f along the interaction space in the amplitron; this technique permits reducing the amplitron problem to a problem of an induced current in an equivalent magnetron. The space charge is represented as phase-focused converging electron spokes; thanks to th6: radial SHF-field component, the electrons are focused as they fly toward the anode, which makes the charge density, in the spoke, under dynamic conditions practically Iconstant. A formula for the induced current-is developed which is applicable to narrow spokes having any base shape. By using the above space-charge representation and the induced-current relation, formulas are deduced for the amplitron gain, output power, and efficiency; they permit calculating principal characteristics and parametersI., of the amplitron under normal conditions of its operation. Orig. art. has: 3 figures and 26 formulas.

Sov. nar. kh-va Chelyab. ekon. adm. r-na, 1958, Nr 2, pp 15-18 ABSTRACT: The cooling systern-of blast furnace Nr 5 is evaporative. Wate r consumption for cooling is reduced, by an average of 98.750/o. Co.n- sequently it is possible to use softened water free of matter in sus- pension and scale-formers. The blast-furnace coolers, and the stove hot-b,!ast and cut-off valves are being re-equipped for.evapor-; ative-cooling. The overall economic effect of the utilization of evaporative cooling will be about 1.5 to Z.0 million rubles per year. M. M. Card 1/1 KREXLYANSKIY, Aleksandr Nikolayevich; redaktor; SXKBNOTA.

In the forties, it became obvious that photo-electron multipliers can be very useful and con- venient ixL the measurement of very weak light sources, e.g. in spectroscopy and astonomy. A new stage in the development of these multipliers began in,1947 when Kallman (Ref.4) showed that, In oonjunction -with a phosphor, electron multipliers can be used as dete6tors of raiAio-activity. Applications to nuclear physics soon followed. Such.multipliers have three important properties, namely, high amplification (up to 8 Card@3 10 109), very small inertia and proportionality between th@@ Photo-electron and Electron Multipliers (A Review) 120-6-:,2/36 input and output signals over a wide range of inputs. a) Multipliers nsed in nuclear physics, Table 1'gives:conplete data for 14 multipliers used in scintillation counters. @The photociathode diameters range from 15 to 190 mm and the number of dynodes from 9 to 13. Both focussed and Venetian blina x 104 to 10 are produeed. 'Amplification factors range from 5 and rise times from 10-8 to 5 x 10-9 seese b) multililiers used for weak.light sources. Characteristics of 6 such multipliers are giveg fully in Table 2. The sensi- tive areagi range from 5 x 5 =6 to 5 x 16 mm2. Two multipliers having.sensitive elements of diameter 15 mm are also given. Sb-v"sl Cs.,O-Ag and Sb-Cs photocathodes are em loyed. Spectral regions covered lie between 2 000 emd 10 000 1. c) Electron multiplier 'S. The first practical use of the secondary electron emission multiplier without a photocathode was described by Allen (Ref.13)- Such multipliers can be Used for counting positive ions in mass-spectrometers. In the Soviet Union-analogous work was carried out by Livshits (Ref-16). The. present aUthors have investigated various multiplier systems as well aa the following alloys for dynodes: Cu-Be, Cu-Mg, Card2/3 ou-Al-mg, Al-Mg-Si. The latter alloy was finally chosen as the Photo-electron and Electron Multipliers (A Review). 120-6-2/36 most convenient technologically. It ispointed out that it would be very interesting to compare Soviet multipliers with foreign. @: Unfortunately, there is almoit a total absence of foreign multipliers in the Soviet Union.

Nr 1, pp. 7o - 77 (USSR) ABSTRACT The Investigation-of the properties of the -19 which are also'described here served as a starting point for the develop--.. . ment of new photoelectron-multipliers. The production of, photo- elec,tron-multiplierd_(PV) better corresponding to the require- ments of nuclear physics than thei . T3Y-19 is needed. The produc-. tion of a sdisfactory spectrometri c multiplier, i.e. of a photo- electron-multiplier with a good amplitude-di8solving-power was considered the most important task. The investigations were ma- de with about loo YY -19 of current production. The results of , .the investigations were used by the authors as the basis for some,modifications at the input ol' the device. Besides, problems viere raised in this connection which referred to a more expe- dient construction and to a number of processes in the product- ion of device. The call for the pairing of the front-photocatho- de-with the dynode-system was fundamental, namely the selection.

Investigations showed that the solution found.A n this :i.,espect is inexpedient in tho@q*J-19 in the elaboration of quality-PV for scintillation-counterB. The necessity of using additionallenses at the input also became evident. The inve- stigation for stability slzwad that most of the devices are un- stablo. - It is shown that in the case that the focusing of the flow of electrons from 'Uhq. cathode is sufficiently sharp (for thi8jtdditional electron-lenSes at the input are necessary) all demands made on the device at the input to the spectrometricEV are fUlfilled. Taking into account that for the purpose of ob- taining PV working more stably, it is necessary to obtain other dynodo-materials beside the Sb-Cs-layers, Ye. S. Shpichenetskiy and I. L. Rogellberg tested some cpecLal alloys in the"Gibro- tsvetiiietobrabotka"-Institute .and finally selected an aluminum- magnetAum alloy as the most convenient one-in the technological respect. The first spectrometric PV was given the laboratory- mark 1 C. The establishment of the input guarantees the spectro- metric properties of every PV which also corresponds to the other fundamental properties - quantum yield at the photocatho- de, uniformity of sensitivity, amplification. The same results (,v lo(:$ collection of electrons) were also obtained in all PV of tho.:t type 1 5 . The muliplier with a highor diew1ving power Card 2/3 with respect to time was given the mark I B.

Type 2 (diameter of thephotocathode.150 M-1) @nd @ Ll (diameter of the photo,mathode 27 mm) were directly developed from this group of multi-pliers. The :Ikrre&ching tests of types 1 C, 1 and 1 B ehowel good results. The further works will follow the following direobions: 1) mastering of the new dynode-system of the circu- lar type with a large number of dynodea, 2) elaboration of a new chron,DXOgical system of a linear type with ring-shaped dynodes and 3) elaboration of chronological PV with a large photocatho- de-surface.

The ilavestigation reported in the article was carried out d!aring 1950 1953,and its aim was to.obtain the. ,data iaccessary for the design of.an electron-optical systein..employing.complex photocathodes.

The experimental tube containing a spherical contlenser was in the form illustreted: in Figure 2. The experimental results are, shown in Figur@iss 3-11.
