Abstract: A device for intermediate storage of condensation water includes a swirl body which causes an inflowing air-water mixture to rotate, and a venturi tube through which the air-water mixture leaves the device. A ring groove in which water accumulates because of the swirl is arranged downstream of the swirl body, and water accumulated in the ring groove is sucked into the venturi tube via one more suction pipes. An expansion zone has an expanded cross-section and a step shaped interior for generating increased surface adhesion. Separating metal sheets in the expansion zone brake the swirl, bind the accumulated gushing water by adhesion forces, and guide it by capillary forces to the interior surface of the expansion zone. Gushing water accumulated at the ends of the separating metal sheets is drained by one or more suction pipes, into the venturi tube.

Abstract: A system for controlling sensor motion during a time-dependent measurement, comprising a drilling assembly having a drill bit at one end and engaged with a drill string extending to a surface location at an opposite end thereof. A sensor is disposed in the drilling assembly for making a measurement of a formation parameter of interest. A non-rotating stabilizer is disposed in the drilling assembly proximate the sensor. The non-rotating stabilizer is adapted to reduce motion of the sensor below a predetermined level during the measurement. In one embodiment the rotational axis of the stabilizer is eccentric with respect to the borehole. In another embodiment, the non-rotating stabilizer has an extendable rib for changing the effective diameter of the stabilizer.

Abstract: A device for intermediate storage of condensation water includes a swirl body in the inlet area, which causes the inflowing air-water mixture to rotate, and a venturi tube through which the air-water mixture leaves the device. A ring groove in which water accumulates because of the swirl is arranged downstream of the swirl body, and water accumulated in the ring groove is sucked into the venturi tube via one more suction pipes. Because of a flow rate reduction and because of the swirl splashing water accumulates in an expansion zone which has an expanded cross-section, and which has air interior surface with a step-shaped construction for generating an increased surface adhesion force. Several separating metal sheets in the expansion zone brake the swirl and bind the accumulated gushing water by adhesion forces, and guide it by capillary forces to the interior surface of the expansion zone.

Abstract: The present invention provides an electromagnetic telemetry apparatus and methods that include an insulating connector that comprises an outer metallic female member that has an inner conical longitudinal surface. In one embodiment, a tubular metallic male member is disposed in the female member, thereby crating an axial conical gap between the male and female members. A conical metallic sleeve having dimensions that substantially correspond to the axial conical gap is disposed in the axial conical gap. The outer tubular surface of the male member is coated with an insulating material, such as a ceramic material. A shoulder at one end of the male member prevents axial movement of the sleeve in one direction and a parallel key between the female member and a stabilizer member prevents rotational movement between the male and female members. The sleeve remains stationary relative to the insulated surface of the male member when the male and female members move longitudinally relative to each other.
