Comrade 7,dorenkop chief engi- neer of the,Krasnoyarok Administration, and comrades Ross and Vinkner, foremen at the local Krasnoyarok LERM, shortened the time of routine service from 200.hours'to one.or one and a half days. Controller com. Kiryanov suggested a new method (not specified) to lengthen the service of manifold tubes. Comrades Koshmanov and Ivanov invented a new device for,starting aircrift-angines withIcurrent from the airfield electric rovements in radio navigation(not specified) and power network. Imp introduction of the automatic landing system have i. vicreased efficiency at the,Xhartkov airport, Comrade Chistota complains of careless hand- ling of equipment in.the Novosibirsk LERM. Comrade Kocharov,,unit chief~.of the Krasnoyarsk Terr.,Adm., reported that his unit lowered the carr7ing cost per 1 ton/km. by 8kopeks .

Thelcontinuoussinusoidal signal is obtained by using time -quantization in which-the continuous signal,is converted into a sequence of pulses -whose,,duty cycle varies according to the input signal changes. The functional dia- -p~ase'frequency converter is given. A continuous reference sinus- gram of a single *oidal signalis'applied to the frequency converter from a starting generator. The schematic diagra~as and descriptions of specific frpquency converter circuits are given. Theoutput,current. and voltage oscilloscope traces corresponding to.the'sin- gle-phase frequency converter driving a two-phase asynchronous motor are presented..'' The output voltage amplitude of this frequency converter may be varied by 50% while its quasisinusoi 4al shape is pres erved. The output frequency and amplitude may also ~be regulated independently..
