Abstract: The present invention relates to downhole apparatus and particularly, but not exclusively, to multi-cycle circulating subs used during downhole drilling operations. Apparatus is provided comprising a piston (242) slidably mounted in a body between positions in which at least one aperture in the body is opened and closed. Movement of the piston (242) is controlled by a pin (86), secured to one of the body and a control member, and a control groove (52) formed in the other of the body and control member for receiving a portion of the pin. An arrangement of elements (232, 276) respectively connected to the control member and body is such as to normally resist axial movement of the control member from a first axial position to a second axial position. A spring (44) is located in a chamber for biasing the piston (242). The chamber is vented by an opening in the body.

Abstract: Absorbable polyester fibers, braids, and surgical meshes with prolonged strength retention have been developed. These devices are preferably derived from biocompatible copolymers or homopolymers of 4~-hydroxybutyrate. These devices provide a wider range of in vivo strength retention properties than are currently available, and could offer additional benefits such as anti-adhesion properties, reduced risks of infection or other post-operative problems resulting from absorption and eventual elimination of the device, and competitive cost. The devices may also be particularly suitable for use in pediatric populations where their absorption should not hinder growth, and provide in all patient populations wound healing with long-term mechanical stability. The devices may additionally be combined with autologous, allogenic and/or xenogenic tissues to provide implants with improved mechanical, biological and handling properties.

Abstract: The invention relates to devices for drilling controlled directional wells. The inventive control device consists of a central hollow element and three hollow out-of-line with respect to each other tubular elements connected thereto. Said central element and the first element on the side of the connection thereof to a spindel are provided for each with its own contact segmental section, thereby forming a pair of contact segmental sections arranged therebetween. Said sections are disposed on the opposite sides with respect to the meridian plane of the spindle in the bending plane of the drill string and at a distance L between the nearest edges of the contact segmental sections along the central axis of the first element at L>=D. The contact segmental section of the first element is deviated from the meridian plane of the spindel in the bending plane of the drilling string in an opposite direction with respect to the reaction torque of a drilling bit. Said invention improves stability, increases the deviation angle of a gerotor type motor provided with a spindle and drilling bit and the drilling accuracy of a bottom hole heterogeneity.
