The tall flange rubber adapter attaches to the inner barrel of a rotating head assembly. A rubber attaches to the tall flange rubber adapter. The rubber secured to the rubber adapter also rotates with the inner barrel thus maintaining the seal with the drill string to divert the drilling fluid from the well to the outlet flange. Fasteners install upward into the adapter and the inner barrel to secure the rubber adapter with the inner barrel. The increased height of the rubber adapter provides additional surface for the fastener to contact. The increased contact of the fastener with the tall flange maintains the fastener within the rubber adapter and the inner barrel to limit fasteners from falling downhole into the drilling area.

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.

In a first aspect there is disclosed a load coupling (10). The load coupling (10) comprises a first coupling member (12) operatively associated with an actuator. The first coupling member has a first coupling formation (16). The load coupling (10) further comprises a second coupling member (14) adapted for operative coupling with the first coupling member (12). The second coupling member (14) includes an attachment formation (15) operatively adapted to attach the second coupling member (14) to a target component to which force generated by the actuator is to be transferred. The second coupling member (14) defines a second coupling formation (24) operatively associated with the first coupling formation (16) of the first coupling member (12). The first coupling formation (16) has (i) a secure orientation relative to the second coupling formation (24) in which the first coupling member (12) is secured to the second coupling member (14) and (ii) a release orientation relative to the second coupling formation (24) in which the first coupling member (12) is adapted to be removed from the second coupling member (14).

The present invention provides an angle changeable apparatus and an oar such that the shaft angle is easily adjustable. Disclosed is an angle changeable apparatus 1 for variably changing an angle of a shaft 110 inserted in a sleeve 10, including: a shaft-side member 20 fixed to the shaft 110; a sleeve-side member 30 fixed to the sleeve 10; and a slider 40 configured to slide between the shaft-side member 20 and the sleeve-side member 30, wherein the shaft-side member 20 has a first guiding part extending in a shaft direction, the sleeve-side member 30 has an elongated hole 31 extending in an oblique direction relative to the shaft direction, the slider 40 has a groove 41c guided by the first guiding part and a slider main body 41 guided by the elongated hole 31, and when the slider 40 slides, the shaft-side member 20 and the sleeve-side member 30 are subject to relative rotation so that the angle of the shaft 110 relative to the sleeve 10 is changeable.

The present patent discloses a device for preventing components from loosening caused by reverse travel, comprising a shell and a cylindrical pin, wherein the cylindrical pin is clamped inside the shell, is in sliding connection with the shell and is capable of retracting into or extending out of the shell. Because of the presence of track positioning, the device disclosed by the present patent can ensure the positioning of the installed components just by performing positioning while fasteners are installed, can avoid the situation of reverse rotation or slip of the components and can be assembled without using any tool or spare parts kit. The device disclosed by the present patent is a hidden device which is automatically telescopic following actions, thereby being convenient to operate and not affecting the appearance.

A connecting device (10) for connecting an article to a carrier (14) is disclosed. The connecting device comprises a securing arrangement (12) for securing the connecting device to the article, and an attaching arrangement (26) for attaching the connecting device to the carrier. The attaching arrangement comprises a first projecting formation (28) for engaging the carrier, and a second projecting formation (32) for insertion through the carrier. When the second projecting formation is inserted through the carrier, a portion of the carrier can be received between the first and second projecting formations, thereby attaching the connecting device to the carrier.
