Abstract: A sliding sleeve for frac operations or the like has a housing, a sleeve, and a shock absorber. The sleeve is movable within the housing's internal passage relative to flow ports. The shock absorber, which can have a cylindrical body, positions partially in the sleeve's internal passage and has a distal end that extends beyond the sleeve. A lip on the sleeve's end is engageable with the internal shoulder. When a ball is dropped on the sleeve's ball seat and pumped fluid forces the sleeve to an open position, the shock absorber absorbs the movement of the sleeve. To absorber the movement, the shock absorber breaks one or more shear pin connections with the sleeve, interposes its lip between the sleeve's distal end and the internal shoulder, and fractures at least a portion of its distal end from the impact with the sleeve.

Abstract: A device for use in the control of mechanical forces. The device comprises first and second terminals for connection, in use, to components in a system for controlling mechanical forces and independently moveable (2, 3). Hydraulic means are connected between the terminals and contain a liquid, the hydraulic means configured, in 4 use, to produce upon relative movement of the terminals, a liquid (4) flow along at least two flow paths (5, 15, 90). The liquid flow along a first flow path generates a damping force proportional to the velocity of the liquid flow along the first flow path, and the liquid flow along a second flow path generates an inertial force due to the mass of the liquid, the force being substantially proportional to the acceleration of the liquid flow along the second flow path, such that the damping force is equal to the inertial force and controls the mechanical forces at the terminals.

Abstract: Vibration damper, including a damping element and a pneumatic spring, wherein the damping element has a container tube, which is connected to a roll-off piston of the pneumatic spring. The roll-off piston is connected via an air suspension bellows acting as a rolling diaphragm to an external guide mounted concentrically and with freedom of axial movement with respect to the roll-off piston, the air suspension bellows and the roll-over piston forming the boundaries of a space filled with pressurized gas. The container tube is prepared for the installation of the roll-off piston by a non-cutting procedure suitable for mass production, wherein a length of tubing having the diameter of the container tube is mounted on a mandrel and clamped at both ends so that its length cannot change, and a pair of flow-turning/rotary-swaging rolls is pressed against the tubing and advanced toward each other to form an area of squeezed material. The rolls are then moved radially while being advanced axially over the area of squeezed material to form a first contour having a bevel, a cylindrical surface, and an axial stop for fitting the roll-off piston to the container tube.

The guide bushing has a radially inner guide tube, the tube passage of which forms a guide. An annular insertion region extends radially outwards on an end region of the guide tube and is inserted with its outer circumferential surface into the upright tube. A plurality of circumferentially spaced ribs of the guide bushing adjoin the annular insertion region axially, and extend radially outwards from the guide tube to outer end surfaces which bear against the inner wall of the upright tube, forming open chambers between them towards the side facing away from the annular insertion region. The upright tube has a color coating which completely covers its outer circumferential surface. Continuous openings pass from the chambers through the guide tube to the interior of the guide tube.
