Title: Method of melt treatment in ladle with varying position of lance
Inventor: LEBEDEV V I
IPC: C21C7/072
Filed: 1995-09-05
Granted: 1998-06-20
Abstract: FIELD: metallurgy; melt treatment in ladle with varying position of lance. SUBSTANCE: in the course of main period of melt blowing in ladle with inert gas, lance position is varied in time, for instance, by saw-tooth law. Information on pressure before lance is smoothed and reduced to the limit lower position of lance. Continuously sought on obtained relationship curve is absolute minimum and information characteristics Δ 1 (t)-Δ 4 (t), are determined. They indicate the actual lance section narrowing due to metal deposition and lance shortening. At low values of information characteristics blowing conditions are realized at the preset level. In case of considerable and slow shortening of lance, blowing is changed to the limit lower position. With further shortening of lance or considerable and slow narrowing of lance due to metal deposit, blowing time is increased in function of narrowing or shortening of lance. In case of intolerable narrowing or shortening of lance, blowing is to be discontinued and lance to be lifted. EFFECT: efficient treatment of melt in ladle due to position varying of lance during blowing, consideration of lance condition and improved quality of melt treatment. 2 dwg

Title: Compensation method of car weight determination and device for its embodiment
Inventor: DJUKOV G N
IPC: G01G19/04
Filed: 1996-03-26
Granted: 1998-10-27
Abstract: FIELD: measurement technology. SUBSTANCE: method consists in conversion of transducer signal proportional to action of wheel pair force on rail to voltage and in determination of weighed car mass. In rail track cross-section in which bending moment and deflection caused by action of wheel pair located above main transducer are equal to zero, measurements are made of signals coming from interfering bending moments of all wheel pairs not positioned above main transducer. Signals of all transducers are converted to root-mean-square voltages. Interfering bending moments are reduced to coordinate of wheel pair position above main transducer. After reduced bending moments are averaged interfering actions of wheel pairs not positioned above main transducer are compensated with due regard for root-mean-square voltages. Mass of car is determined with account of electromechanical sensitivities of main and auxiliary transducers. EFFECT: enhanced accuracy of measurement. 2 cl, 4 dwg

Abstract: FIELD: construction engineering. SUBSTANCE: this relates to reconstruction of 4-5 story houses made of large prefabricated panels, large blocks or brick in condition of urban building-up areas. According to method, reconstruction procedure is as follows: arranged along longitudinal walls of building beyond zone of compressed thickness of ground of foundation base are cast-in-situ piles with strip pilework. Installed on strip pilework is load-bearing metal or reinforced concrete framework to entire height of building. Mounting platform is erected beyond limits of longitudinal walls at one of ends of building. Height of mounting platform is equal to height of building. Longitudinal guide members are arranged over upper band of framework and mounting platform. Assembled on aforesaid guide members above mounting platform on rolls are large-size sections in the form of three-dimensional structural modules which are successively moved by means of rope-and-pulley system and pulling winches along longitudinal guide members to design position. Each structural module is fixed in design position by concreting of rolls and by connecting given structural module with preceding module. Application of aforesaid method allows for increasing useful floor area of building with retaining possibility for normal functioning of existing premises through entire period of reconstruction irrespective of weather conditions. Work performing cycle and labour-intensity are reduced. In addition, aforesaid method allows for not using load-lifting facilities moving along building for erection of added stories.
