A protection device for preventing damage to an elongate flexible member passing through an aperture including a body portion adapted to be inserted into the aperture in a first direction and having an internal passageway for allowing movement of an elongate flexible member therethrough, and at least one latching element pivotally mounted on the body portion. The protection device can be used for protecting an elongate flexible member passing through an aperture in a support pillar of an offshore turbine generator. A method of removing the protection device from an aperture is also disclosed.

Methods, systems, and devices to enhance fracturing fluid delivery to subsurface formations to enhance hydrocarbon production from the subsurface formations may include providing a manifold coupling having a manifold coupling passage with a manifold coupling axis. The manifold coupling may include a first inlet passage positioned to provide fluid flow between a first fracturing fluid output and the manifold coupling passage, and a second inlet passage positioned opposite the first inlet passage to provide fluid flow between a second fracturing fluid output and the manifold coupling passage. The first inlet passage may have a first inlet passage cross-section at least partially defining a first inlet axis extending transverse relative to the manifold coupling axis. The second inlet passage may have a second inlet passage cross-section at least partially defining a second inlet axis extending transverse relative to the manifold coupling axis and not being co-linear with the first inlet axis.

A coupling device suitable for interconnecting two beam ends is provided, wherein the beam with the beam end has an elongate axis, where on a first beam end is arranged first interconnection units having two first parallel flange elements arranged with a mutual first distance x, wherein in each flange is designed a cut-out with a cross-section in the plane of the flange; a second beam end is arranged a second interconnection unit having a second flange, the width of the second flange across the plane of the second flange is smaller than or equal to x, and where largely perpendicular to the plane of the second flange, a connecting element protrudes on each side of the second flange, the cross-section of the connecting element in the plane of the second flange allows insertion of the connecting element into the cut-outs of the first flanges on the first beam end.

A retention system for retaining a milling drum to a driveshaft of a milling assembly. The driveshaft is powered to drive the milling drum about an axis. The retention system includes a retention member coupled to the driveshaft between a first position and a second position. In the first position, the retention member restricts a disengagement between an engagement surface of the driveshaft and a mating surface of the milling drum, inhibiting a release of the milling drum from the driveshaft along the axis. In the second position, the retention member provides clearance for the disengagement of the engagement surface and the mating surface, facilitating the release of the milling drum from the driveshaft along the axis.

Joint element for joining the side profiles of a first and a second cable ladder end-to-end with each other, preferably the side profiles being of the so-called hexagonal type, which joint element comprises on one hand a longitudinal gripping edge, which is connectable over the first longitudinal edges of the side profiles, and on the other hand a locking edge, which connects to the second, oppositely situated longitudinal edges of the side profiles, the locking edge of the joint element being provided with locking means for the fixation of the joint element against the side profile, wherein the locking means is formed as a locking tab that is formed with a free end and integrated with the locking edge. The invention also concerns a method for joining the side profiles of a first and a second cable ladder end-to-end with each other using such a joint element.

A fitting splice plate connects a cable tray fitting to a cable tray section. The fitting splice plate includes a guard extending in an outboard direction from a second longitudinal portion of a plate body adjacent a first longitudinal portion of the plate body. The guard is adjacent one of an upper side and a lower side of the second longitudinal portion. The fitting splice plate may include both upper and lower guards.

A structure for a semi-static tensile member and a method for producing the semi-static tensile member. A tensile member is prepared by attaching terminations to an assembly of synthetic filaments. The tensile member is then attached to a loading apparatus that subjects the tensile member to a pre-defined loading process. The tensile member is thereby conditioned to a stable length. A bend restricting device is attached to the cable assembly proximate the point where the synthetic strands exit the termination and enter the freely-flexing portion of the cable. The bend restricting device is configured to permit periodic inspection of the cable in the region it covers.

A folding joint and a folding bicycle frame are provided. The folding joint includes a hand lever, a first joint connected to a first connecting member, and a second joint connected to a second connecting member, where the hand lever is hinged to the first joint and/or the second joint. When the first joint and the second joint are in a closed position, the hand lever is rotated to a first position. When the first joint and the second joint are in a separated position, the hand lever is rotated to a second position. The hand lever is provided with a first engaging portion. When the hand lever is in the first position, the first engaging portion is configured to engage with a second engaging portion to restrict the first joint and the second joint to be in the closed position.
