LIGHT-BEAM BRAZING Russian patent published in 1997 - IPC

FIELD: brazing sheet metals and nonmetallic materials. SUBSTANCE: device for light-beam BRAZING uses inlet and outlet optical assemblies interconnected by a multiple-strans light conduit of single light-conduit fibres. The inlet and outlet optical assemblies have elliptical reflectors consisting at least of two parts made as surfaces of revolution of ellipses, whose longitudinal axes are positioned at an angle to the axis of symmetry of the respective assembly and intersect it in one of the focuses of the reflectors. The other reflector focuses represent focal circumferences. The multiple-strand light conduit is enclosed in mountings in the inlet and outlet assemblies, having holes for placement of the ends of single light conduit fibres in them. The holes in the mountings are positioned on the focal circumferences of the reflectors. Each reflector has a cover with a protective shield. EFFECT: enhanced reliability. 3 dwg
