Abstract: A welded structure makes a relationship between one intermittent weld which fixes a long member to a base material and the other intermittent weld which fixes a plate-shaped member to the long member appropriately respond to a type of a load which dominantly acts on the long member. A lower long side edge of a beam member which serves as the long member is fixed onto a machine body frame which serves as the base material by intermittent welds. A top plate which serves as the plate-shaped member is fixed onto an upper long side edge of the beam member by the other intermittent welds.

Abstract: A fastener element for transmitting a load to a machine part. One of the fastener's longitudinal extension axial ends is fixed with the machine part. The load acts onto the fastener at the other longitudinal extension axial end in a load area. The fastener comprises a plurality of longitudinally extending base parts, including the load area. The base parts are connected to each other by corrugations. To reduce shear in the fastener, a height of the corrugations is substantially constant along a first extension in a fastener longitudinal direction, extending from the machine part to a transition region. The load area is arranged along a second extension in the fastener longitudinal direction adjoining the first extension. Along the second extension, the corrugations height is reduced from the transition region, becoming zero at a final section of the fastener in the axial end region remote from the machine part.

Abstract: A dynamic platform with extending struts has fastened thereto a bi-directional torsional power unit to selectively deliver force opposing either extension or flexion, and to provide assistance in a respective opposite direction. The power unit is threadably mounted on a hinge pin (spline) centrally located on the platform, and is latched to a catch assembly radially located thereto, the hinge pin of the platform communicating with one end of a torsion spring of the power unit and the catch assembly communicating with another end of the torsion spring, to selectively deliver the extension/flexion force. The power unit can be detached, with simple manual operation of the catch assembly, without tools, flipped over and reattached to the same platform attachment points to switch (reverse) extension torque to flexion torque and vice versa.

Abstract: Systems and methods of fencing systems are provided that incorporate tri-truss assemblies and/or self-closing gates. A tri-truss assembly may provide stability and support to a gate that is part of a portable or temporary fencing system. A tri-truss assembly may be configured to support a self-closing gate that is part of a pool fence. A tri-truss assembly may include three vertical support members. Two of the three vertical support members may include pins configured to be placed within pre-drilled holes in a surface in order to maintain the tri-truss assembly upright. A third vertical support may be a different length (shorter or longer) than the first two vertical support members and include an adjustable foot, such as a threaded bolt, configured to contact the surface and provide additional stability and/or support.

Abstract: A failsafe pin for providing a backup load path for attaching a gas turbine engine to an aircraft structure is provided with a driving element that allows a torque to be provided to the pin in order to check whether the pin has been engaged, and thus whether a primary load path has failed. The pin is provided with anti-tamper arrangements in order to ensure that the pin itself is not compromised when being tested for engagement.

Abstract: An assembly of a first and second constructional part is provided, wherein the first constructional part has a first end and an opposite second end connected by a central part extending substantially perpendicularly to a surface of the second constructional part. The first end of the first constructional part is connected to said surface of the second constructional part with an encapsulating material at least partly surrounding said first end and adhering to said surface of the second constructional part. The first constructional part between its first and second ends is provided with at least one protruding part. The first constructional part in contact the encapsulating material is provided with a flange of which the vertical projection on said surface of the second constructive part completely covers the vertical projection of the protruding part on said surface. A method for making the assembly is provided.

Abstract: A stanchion includes storage for a linkage member. The stanchion includes a hollow pole and a cap piece inserted into the top portion of the pole. Vertical movement of the cap piece may provide clearance for a linkage opening to allow the linkage member to be pulled from or pushed into the interior of the hollow pole.

Abstract: A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for land reclamation. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for land reclamation.

Abstract: A system and method to eliminate the need for a dummy run comprises a logging assembly to detect the position of one or more blow-out preventer (“BOP”) rams and a hang off location. During a logging operation, the logging assembly logs the positions of the BOP rams and wear bushing. The logged positions are then used to determine the correct placement of the subsea test tree (“SSTT”) in relation to its hanger. Thus, the need to perform a dummy run is eliminated because correct placement of the SSTT can be determined during routine logging operations.
