Abstract: A superplastic forming machine comprising first and second parallel spaced apart platens, each arranged in a plane normal to a displacement axis; a first displacement mechanism connected to the first platen and configured to displace the first platen along the displacement axis; a locking mechanism which can be configured in a locked configuration in which the first locking mechanism prevents displacement of the first platen along the displacement axis and an unlocked configuration in which the locking mechanism does not prevent displacement of the first platen along the displacement axis; and, a second displacement mechanism connected to the second platen and configured to displace the second platen along the displacement axis towards the first platen the second displacement mechanism being a self-locking displacement mechanism.

Abstract: A sealing assembly comprising a plurality of components including an upper sealing element and a lower sealing element, the sealing assembly configured to encircle a tubular string positioned within a casing of a wellbore. The sealing assembly is configured to be actuatable to extend sealing elements between the tubular string and an inner surface of the casing to form a fluid seal between the tubular element and the inner surface of the casing.

Abstract: A sealing assembly is disclosed, the sealing assembly comprising a plurality of components including an upper sealing element and a lower sealing element, the sealing assembly configured to encircle a tubular string positioned within a casing of a wellbore.

Abstract: A lower packer, seal stinger, upper packer, running tool, and setting tool is positioned into the wellbore. A force is applied by the setting tool, which causes the seal stinger to be pushed into a seal receptacle of the lower packer. The seal stinger is pushed by pushing the running tool which causes the upper packer to be pushed which causes the seal stinger to be pushed. A force is also applied by an internal rod of the setting tool to pull the running tool which causes the running tool to hold the lower packer in place as the seal stinger is pushed into the seal receptacle. The running tool and setting tool is then removed from the wellbore, wherein the lower packer, seal stinger, and upper packer comprise the straddle assembly.

Abstract: An apparatus (100) for forming a laminate of pre-preg composite material comprises supply means (200) to supply pre-preg strip (400) to a stationary mandrel (300). The pre-preg strip (400) is formed into a tube (410) on the mandrel (300), and is driven to both rotate relative to the mandrel and to move axially along the mandrel. In this way it can be dispensed from an end of the mandrel (300) and formed in to a further pre-preg strip (420) with off-axis fibres.

Abstract: A mattress lift for elevating a bed mattress and tucking in sheets or bed covers beneath or under the bed mattress between the bed mattress and a box spring or other supporting surface comprising a lift device including a base or body having a longitudinally disposed substantially oblong recess formed in the upper surface thereof with a longitudinally disposed oblong slot formed in the base or body symmetrically disposed within the longitudinally disposed substantially oblong recess, a lift handle formed or coupled to a proximal portion of the base or body configured to be grasped by the user, a lift ramp including an inclined surface formed or coupled to a distal portion of the base or body configured to slide between the bed mattress and box spring to tuck the sheets or bed covers therebetween and a lift support device including an upper lift coupler movably or slidably disposed within the longitudinally disposed substantially oblong recess interconnected or coupled to a lower lift support member disposed b
