Abstract: FIELD: mechanical engineering; turbocompressors. 
     SUBSTANCE: according to known method of surge control including stabilization of complex of parameters characterizing position of operating point of compressor in accepted system of coordinates at level of task determined by line of control shifted through preset value in safety zone from surge line to zone of stable modes of operation of compressor by formation of control action onto position of surge valve by closed control circuit containing proportional and integral parts, value-of deflection of operating point from control line in direction of surge line is compared with preset threshold value, and if said deflection exceeds threshold value, formation of proportional part of control action is done at amplification factor in jump increased by preset number of times.  Amplification factor of proportional part is increased 10-100 times, determining its particular value at adjusting the system so that control action formed by proportional part at increased amplification factor should provide, firstly, maximum constructionally possible speed of opening of surge valve, and secondly, complete opening of valve when operating point reaches surge line.  Formation of control action by proportional part at increased amplification factor is continued until operating point returns to control line.  When operating point reaches control line, amplification factor of proportional part is reduced to initial value providing stability of control process. 
     EFFECT: increased accuracy, economy and efficiency of surge control.

Granted: 2006-02-27
Abstract: FIELD: medicine, surgery. 
     SUBSTANCE: the present innovation could be applied in the course of endoscopic operations dealing with extracorporal development of a flat knot loop, spiral and a knot. The spiral should be formed out of 3 coils. One should wind one end of ligature around a flat knot loop with a coil to locate both ends at one side. Then the same end of ligature should be introduced into a coil to be tightened at simultaneous tension of another end to develop a knot. Then one should tighten two knots as a counter-tightening lock around each loop's branch successively with free end of ligature. As a result, formation of a spiral out of three knots enables to deform a flat loop that enhances friction power and makes the knot to be more compact and stronger. The innovation decreases the chance of a sliding knot for unbinding due to tissue pressure upon it from inside. 
     EFFECT: higher efficiency.
