Abstract: A method of manufacturing a charge dissipative surface layer on a member made from or consisting of a dielectric polymeric material or polymer-based composite which is intended to be used in space and other extreme environments, the member having at least one surface, in particular two opposing surfaces, each of the surfaces having a flat or a three-dimensional shape. The method includes carbonizing the at least one surface of the member in a vacuum environment through ion bombardment with simultaneous surface renewal in a dynamic way, by bombardment of the at least one surface with an ion beam formed in a gaseous linear high-current technological ion beam source of rare gas and added predetermined amount of a carbonaceous gas in the same ion beam gas admixture in order to achieve a treated carbonized surface layer with a uniform surface resistivity in a charge-dissipative range.

Abstract: An ultrasound device for the treatment of surfaces and welded joints is disclosed. The device has a housing with a plurality of shaped slots formed therein. A reciprocally moveable sleeve is attached to the housing, and contains an ultrasonic transducer. A reciprocally moveable attachment is attached to an operating end of the sleeve, and has a detachable working head mounted thereon. A pin is positioned in a pin slot on the housing, and anchors the sleeve to the housing to limit movement of the sleeve. The pin is biased towards the front of the pin slot by means of a spring, and a moveable spigot provides a predetermined contact force between the ultrasound device and a work surface. The spigot has spigot pins that are inserted into the plurality of shaped slots in the housing in order to restrict axial movement of the spigot, thereby providing added compression or tension to the spring in order to provide the predetermined contact force.

Abstract: Ultrasound Device for Improvement Treatment of Parts and Welded Joints; said device comprises a housing with a handle and sliding guides, wherein a sleeve with an attachment possessing the ability of reciprocal motion is affixed; said sleeve contains, over vibro-insulation packing, an ultrasound transducer installed on the nodal plane and connected to the oscillation velocity transformer; a temperature sensor and a sensor of the sleeve position in relation to the housing; a forced air-cooling system for the transducer based on feeding compressed air at the butt end of the sleeve and discharging it in the area of the exit opening of the velocity transformer, said transformer being in contact with the striker tips capable of the reciprocal motion and positioned within a working head; the cylindrical end of said working head is mounted on the attachment with the ability of rotation and quick removal; the movement of the sleeve is limited by means of a pin anchored on the sleeve and positioned in a longitudinal s
