Title: Method for measuring of absolute value of body density
Inventor: KAPRANOV BORIS I
IPC: G01N23/20
Filed: 1994-04-08
Granted: 1997-08-10
Abstract: FIELD: instruments, in particular, Compton computer tomography. SUBSTANCE: method involves treating body in different directions with gamma and X-ray collimated beams which powers are E 1  and E 2 , detection of reflected radiation with collimated detectors D 1  and D 2  and calculation of absolute value of density by means of given algorithm. Initially axes of collimators and detector are oriented so that they intersect in point which is located on surface of body. Then, method involves discrete movement of rigid system of source and detector in direction of given coordinate X which runs through body and measurement of radiation flow N 1i  that enters detector D 1  for each step of movement, which is run until intersection point of axes of source collimators and detector reaches inner surface of body. Then method involves setting source power to energy of quanta which are dissipated by angle θ in direction of detector E 2 = E s (θ), locating radiation source with energy E 2  in position of detector D 1 , locating detector D 2  in position of radiation source with energy E 1  and discrete movement of system of source and detector along X coordinate towards body surface. Simultaneously method involves measurement of radiation flow N 2i  which is detected for each step of movement until intersection point of axes of source collimators and detector reaches body surface. Then given algorithm is used for calculation of density ρ i  in series for each movement step. EFFECT: increased functional capabilities. 2 dwg

Title: Machine for pipe cutting
Inventor: LENKEVICH YURIJ EVGENEVICH
IPC: B23D21/14
Filed: 1995-08-22
Granted: 1997-06-10
Abstract: FIELD: mining industry, oil and gas industry. SUBSTANCE: invention deals with pipe cutting by lowering of machine into interpipe clearance of string of pipes to be out. Fluid from pipe conduit goes to central conduit, then goes into ring space through radial conduit, comes through conduits from body into interpipe clearance and rises through it to well-head. Pressure of fluid caused by velocity head acts on piston since summary passage of radial conduits is less than passage of pipe conduit. Under action of force caused by this velocity head piston moves downwards and presses on cutters with its end forcing them turn about axes. Cutters come out of grooves with turn. Cutters acts on pusher which moves together with stepped shank in axial hole. Moving pusher compresses spring which rests against thrust plate with other end. Cutting process starts from moment of touching of internal surface of cut casing with cutters. EFFECT: improved cutting efficiency. 2 dwg
