It ts a two-port with matrix a,, a,, a21 a n ! Connected in cascade with other two-ports it increases the signal by a factor of K in one direction and by I/K in the other,'' independently of the input impedances of the two-ports on either side.

The physical realization of ideal power converters is the subject of the present article. Analysis showd that the circuit of Fij.1 will behave as an ideal power converter under certain conditions.

The authors list several applications in measurement techniques. - The most inter-esting application is as a negative-resistance amplifier (rig.4 and 5). Bridging the converte'r (Fig.4) gives a short- circuit-stable negative-resistance amplifier, putting the impeo.-ince in the common lead (Fig-5)'gives an open-circuit-stable amplifier.

TITLE: The Stability of the Modulus of Amplification of a Feedback Ampli- fier iLf PERIODICAL: Elektrosvyazl, 1960,NNo. 6, pp. 14 - 17 TEXT: The author discusses the disagreement between the formula and , the verbal definition of the quantity of sensitivity of a feedback amplifiel-,.which is found in the well-known book by G. Bode (Ref. 1). Here, the sensitivity is defined as "the ratio of the percentage change of the value /Ato the per.,entage change of originating in this case". The author states that complex values have been u ed in the formula, while their moduli have been used in the verbal definition. Bode further holds that a flat frequency characteristic T is best within the limits of the working range. In the author's opinion, a flat freqUEn/ cy characteristic is not the optimum solution for obtaining-a high degree of stability of the amplification modulus ~p at an instability of the value(A. He introduces the conception of the modulus of sensitivity Sn which determines the stability modulus of a feedback amplifier.

In order to obtain the smallestpossible values of noisy real resistances should be eliminated as far as possible, and for this purpose it is of advantage to use a two-winding trans- former to supply bridge feedback.

Installations for the utilization of waste G's are planned in Lisichansk, Chirchik, Rustavi, and other cities. The cost of the C02 supplied by these installations will amount to 275-300 rubles per ton. Shipped-in GO? may be cheaper than the locally produced variety, provided the dry ice is supplied in containers.

Supplying the Industry With COZ Gas SOV/137-59- 1-734 C02 may also be obtained from fuel G's of local industries by the absorption- desorption method. This method involves the expenditure of chemical reagents, electrical energy, water, and steam. The cost of the COZ thus obtained is 650- 850 rubles per ton. In the case of small installations, producer (combustion of solid or gaseous fuel in a stream of 02) and sulfuric-acid (chemical reaction of CaG03 with H2S04) methods may be employed. The cost of C02 produced by these methods amounts to 935 and 750 rubles per ton, respectively. A. M.

Farberova, 1. 1.-- TITLE: Wear (abrasion) of plastics and methods for its evaluation PERIODICAL: Plasticheskiye massy, no. 1, 1962, 60-66 TEXT: Specimens of plastics were tested without lubrication at low speeds and loads, either with monocorundum abrasive paperM150 (M 150), rocT344-57 (GOST 344-57) on Schopper machines (produced by the Metallist Plant, Leningrad) ~ or with steel-wire cloth r-Of,"T'3826-47 (GOST 3826-47) on Grasscli machines. The nondimensional wear coefficient v for plastics does not depend on the cross section of the specimens~ The exchange of abrasive paper and wire cloth affects neither wear nor the spread of test results, which was estimated from the mean square deviation a and from the variation coefficient 6 -100%, Since the spread increases during the abrasion of small masses, 6
