Abstract: A shoe is for a hoof of an animal. The shoe has a sole for being mounted to an underside of the hoof of the animal. The shoe comprises at least two fixation areas for fixing the shoe to the hoof in operational use, wherein the fixation areas are located on opposite sides of the hoof, each fixation area comprising at least one protruding element, which penetrates, in operational use, into the hoof for fixing a position of the fixation area relative to the hoof. Each fixation area is connected with the sole by at least one elastic connection. The shoe can comprise an elastic clipping element for applying by an internal pretension force in the elastic clipping element, in operational use, an inwardly-directed pressure on the fixation areas for pressing the protruding elements into the hoof. A mounting tool is configured for applying the elastic clipping element to the shoe.

Abstract: A shoe for the foot (5) of an animal. The shoe includes a sole (10) and an upper part (20) that are connected to each other, and where the upper part (20) has an opening with a tightening mechanism (70) to tighten the shoe against the foot (5). The tightening mechanism (70) includes at least one attachment part (50) which is secured to a toe portion (15) or a heel portion (35) of the sole (10), and the at least one attachment part (50) is located lower than the tightening mechanism (70) in the upper part (20) so that the upper part (20) is drawn down against the sole (10) upon tightening to give a snug fit around the foot (5).

Abstract: A shoe for the foot 5 of an animal, the shoe comprising a sole 10 and an upper part 20 that are connected to each other, and where the upper part 20 comprises an opening with a tightening mechanism 70 to tighten the shoe against the foot 5. The tightening mechanism 70 comprises at least one attachment part 50 which is secured to a toe portion 15 or heel portion 35 of the sole 10, and where the at least one attachment part 50 is located lower than the tightening mechanism 70 in the upper part 20 so that the upper part 20 is drawn down against the sole 10 on tightening to give a snug fit around the foot 5.

Abstract: A sole for the foot of an animal, where the sole is constructed such that during use it maintains a stable and unchanged position between the foot and the sole independent of the surface and independent of whether the foot is loaded during the down step or unloaded during the up step, and furthermore where the sole, when in use, forms a natural and dynamic bio-mechanical anatomical chamber which takes up frictional forces that arise between sole and foot in a self-adjusting way in relation to the forces that are applied. The sole has damping and energy control of forces caused by internal and external influencing factors, i.e., the animal's foot and the surface on which the sole is used, respectively.

Abstract: The present invention relates to a saddle for riding or carrying other load. The saddle includes at least two segments forming a frame, wherein, between the segments and between the right and left hand sides of each segment, flexible segment links allowing for relative movement thereof are provided, with the size, shape, flexibility, and stiffness of each segment being adapted to achieve an optimal weight distribution and freedom of movement, the segments and segment links or hinge elements are configured to allow for a relative independent movement thereof.

Abstract: A pressure-driven apparatus sequential controls a multiphase operation, e.g., of a cementing head. A transmission arm including a pawl is supported on a cam shaft connected to a pawl cylinder having a built-in return force, directional control valves with a spring return member and roller, operated by the cam plates of the cam shaft, that are staggered relative to each other in a predetermined angle to a pawl disk supported in bearings. The pawl cylinder will rotate cam shaft to a predetermined angular position in the same rotational direction each time the system is supplied with pressure, and operate the directional valves with rollers, whereby the directional valves will apply pressure to actuators present so that cementing valves or other types of valves will open for a predetermined period of time until a timer control shuts off the pressure supply, the pressure is discharged, and the pawl cylinder returns to the starting position thereof.

Abstract: Sole (5) for a shoe adapted for use on hoofed or cloven-hoofed animals where the sole (5) at least comprises: a forward (10) and a rear part (11) plus at least a coupling/joint (14) which allows the at least one forward part (10) and the at least one rear part (11) to move completely or partly independent of each other. The invention also discloses a shoe (1) for use of said sole (5).

Abstract: The present invention relates to a cementing or inflow regulation valve for conducting cementing operations or inflow regulation in a wellbore comprising a casing or tubing (2), wherein the cementing or inflow regulation valve (1) is inserted between the casing or tubing (2), wherein the cementing or inflow regulation valve (1) comprises an inner sliding sleeve valve (3) which in a closed position covers a number of openings (4) through an outer pipe (5) of the casing or tubing (2) and which in an open position uncovers said openings (4), the sliding sleeve valve (3) comprising a releasing means (6) requiring a certain force to be released both from the closed position to the open position, and vice versa.

Abstract: A cementing valve for conducting cementing operations in a wellbore comprises a casing, wherein the cementing valve comprises an inner sliding sleeve which in a closed position covers a number of openings through an outer pipe surrounding the inner sliding sleeve, and in an open position uncovers said openings, the sliding sleeve comprising an actuating unit requiring a predetermined force to be actuated from both the closed position to the open position and vice versa, an engaging unit being arranged on the inside of the sliding sleeve for being engaged by a well running tool comprising corresponding gripping unit. The cementing valve comprises at least one shear pin designed in such a manner that a predetermined force is necessary to overcome the shear resistance of the shear pin, the sliding sleeve being arranged for moving further past the shear pin when the shear pin breaks until the actuating unit engage a groove.

Abstract: The invention relates to a pressure-driven apparatus for the sequential control of a multiphase operation, e.g. of a cementing head. A transmission arm (3) comprising a pawl (4) is supported on a cam shaft (9) connected to a pawl cylinder (1) having a built-in return force, directional control valves (8, 8?, 8?, and 8n) with a spring return member and roller (7), operated by the cam plates (6, 6?, 6?, and 6?) of the cam shaft (9), that are staggered relative to each other in a predetermined angle to a pawl disk (5) supported in bearings (10) and (10?).
