METHOD OF FILLING OF LIGHT SOURCES AND DEVICE FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: in manufacture of light sources for their filling. SUBSTANCE: at filling of incandescent lamps with gaseous mixture on an evacuation automatic machine, components of filling gaseous mixture are fed alternately at different seats of the evacuation automatic machine. The sequence of proportioning of gaseous mixture components is accomplished in growing dependence on their pressure at filling; the component with a low molecular weight is the last to be proportioned. Light sources are filled through a nozzle installed between the reducer valve and slide valve of the evacuation seat of the evacuation automatic machine; the diameter of the nozzle diameter is calculated by the formula given in the description of the invention. EFFECT: saved components of filling gaseous mixture; improved homogeneity of gaseous mixture; enhanced accuracy of proportioning of gaseous mixture components. 5 cl, 3 dwg , 1 tbl
