Abstract: A full opening subsurface control valve for use in subsurface closure of a well annulus; includes a body (32) with a sleeve (50) reciprocably disposed in the valve body. The body is releasably attachable to an upper tool string portion, and the sleeve is attachable to a lower tool string portion. An actuator arm (72), mounted on the body and stationary with respect thereto, engages a ball valve element (66). When the body and sleeve are in a relatively converged position, the ball valve element is in a closed position (as shown). When the body and sleeve are in a relatively extended position, the ball valve is in an open position, such that the ball valve element, body and sleeve define a substantially unobstructed flow passage through the valve. A spring (156) is utilized for relatively biasing the body and sleeve toward the converged position. The weight of the lower tool string portion overcomes the spring force such that the valve is maintained in an open position as it is longitudinally positioned in the well bore. A pressure balancing piston can be provided for balancing forces exerted by test pressurization of the valve so that undesired opening of the valve is prevented.

Abstract: For some applications of slide layers, for example in connecting rod bearings of internal combustion engines, for individual sites of a formed piece, high load bearing capability are required while for other places of the same formed piece good embedding abilities are demanded. A composite material with a slide layer applied by cathode sputtering of a tightly cohesive matrix and an insoluble component distributed statistically in it, is adapted to these opposite demands in that the diameter of the particle of the insoluble material has gradients at predetermined sites, which extend parallel to the surface of the slide layer, and to which slide layer hardness gradients correspond. These gradients are generated during the cathode sputtering process in the substrate to be coated to form a growing slide layer having temperature gradients which are maintained and which extend parallel to the substrate surface.

Abstract: Toroidal-core transformers normally have a plurality of windings wound concentrically spaced at a distance from the cross-section of the toroidal-core (9). By means of insulating rings (7), preferably of roof-shaped design, which are supported on opposite sides of a toroidal-core, a plurality of concentric windings (6, 10) can be fitted, with a defined separation from the toroidal-core. In comparison to insulation arrangements with plastic housings (troughs) this results in improved dielectric strength with the same dimensions. Moreover, toroidal-core transformers of different core heights can be produced with the same types of insulating ring. <IMAGE>
