Granted: 2000-01-27
Abstract: FIELD: control systems of flight vehicles, in particular, guided missiles. SUBSTANCE: the design is based on registration of actuator operation in response to zero, direct and harmonic input and output signals. The output signal is subjected to a harmonic analysis concerning the direct component, amplitude and phase shift of the first harmonic of expansion into a Fourier series. Measured are the free-running frequency and amplitude from the feedback transmitter output in the absence of an input signal to the actuator and compared with the rated ones. Then the signal from the feedback transmitter is passed via a ripple filter, whose time constant is selected from the condition of effective suppression of the free-running frequency at a minimum sluggishness of the filter. The control actuator zero drift and static gain are judged by the value of the filter output voltage; and the value of phase shift - by the value of shift of the filter output signal relative to the input one. EFFECT: objective control and enhanced accuracy, reduced labour input and cost of control. 3 cl, 5 dwg

Abstract: FIELD: biotechnology. SUBSTANCE: invention can be used in medicine and veterinary for treating and preventing conditions caused by disturbances in composition and functions of normal human or animal microflora. Bifid bacteria and lactobacilli are isolated simultaneously in the form of natural human or animal intestinal complexes employing decontamination of intestinal contents from foreign microflora. Sampled material is repeatedly diluted with a liquid selective nutrient medium suited to isolate and culture bifid bacteria and lactobacilli. In particular, allochtonic microflora is removed by adding blood serum material from the same host diluted by 1 mln times. Culturing is carried out at 38 C for 48 hr and cultured material is then transferred on the same nutrient media, which are free of selective agents added. Resulting biomass contains bifid bacteria and lactobacilli that really represent indigenous host microflora. This mass can further be used to restore human intestinal microflora and that of valuable animal and bird specimens.
