Filed: 1996-10-09
Granted: 2003-09-20
Abstract: FIELD: methods of control of drilling by drilling machine. SUBSTANCE: in realization of claimed method, position of drilling is controlled by pressure acting on, at least, one piston movable in direction of drilling machine front end from position corresponding to optimal impact point. In this case, for preservation of contact of drilling bit with drilled rock, pressure acting on, at least, one piston movable in direction of drilling machine front end from position corresponding to optimal impact point, is built-up of such value that force developed by this piston for pushing the drilling bit is less than force of drilling machine feed. According to the other version of claimed method, pressure acting on, at least, pistons of one group is controlled for changing drilling position. Drilling machine has, at least, three groups of pistons in which length of working stroke rises from the first to third groups. For control of drilling, bit shank is installed in preliminarily determined preset impact point by supply of working fluid at sufficiently enough high pressure exerted on, at least, those pistons of three groups whose working stroke corresponds to impact point determined so that force developed as a result, acting on shank exceeds force of drilling machine feed. Invention also covers drilling machine having working fluid channels separate from one another and leading to piston working spaces and means for supply of working fluid to working spaces behind pistons and located so that pressure acts on them irrespective of one another. As a result, drilling is controlled rapidly and simply, and machine impact power may be accurately calculated. EFFECT: higher efficiency of method. 17 cl, 5 dwg

Abstract: FIELD: optical diffraction methods of nondestructive test. SUBSTANCE: invention is related to optical diffraction method of nondestructive test of structural geometrical periodic parameters of opaque woven cloths of any nature. It can also find use for test of any flat textile cloths transparent or non- transparent for light which are inaccessible for direct diffraction analysis but accessible for photographing, for instance, museum woven specimens. In accordance with proposed technique negative or positive frontal image of tested material placed on any transparent base, for instance, on photographic film, generated by its direct or backward illumination when it is illuminated by parallel beam of monochromatic light with wave length λ perpendicular to its surface can be used in the capacity of tested specimen. Value of structural parameters of tested material is evaluated by symmetry and mutual arrangement of maxima in diffraction picture produced by image of tested material put on transparent base. Density (P w ) of the weft is evaluated by value of distance measured between adjacent rows of basic maxima (ΔX) going in direction of thinned filaments in image of tested material and value (P wt ) of warp texture is evaluated by value of distance measured between adjacent rows of basic maxima ΔY going in direction of filaments of warp texture in image. In this case values P w ,P wt  are calculated by formulas P w = KΔX/(Lλ);P o = KΔY/(Lλ) where K is magnification factor of image of tested material which is equal to relation of true dimension of tested material to dimension of its photographic image on transparent base; L is distance from image of tested material to screen.
