Abstract: A mixing assembly includes a coupler with a temporary seal that is connected to a first container containing mix ingredients. An internally and externally threaded insert is threadedly mated with the internally threaded coupler in an initial position short of breaching the temporary seal. A second container is screwed into the internally threaded insert. Sealing relationships are formed between the coupler and the insert, and between the insert and the received second container. Once the second container is secured to the insert, the coupler is screwed downwardly toward the insert to cause the insert to threadedly advance toward and eventually breach the temporary seal to enable contents of the first container to mix with that of the second container.

Abstract: A coupling assembly (100) is provided having a first member (110) and a second member (120). The first member is able to be coupled to the second member by relative movement along a coupling axis. In use, a tension component (140) carries the axial tensile load of the coupling assembly. In order to decouple the coupling without removing the tension component (140), it is necessary to apply sufficient tensile force to fracture the tension component. Thus the tension component is designed to fracture in to two parts along a single fracture (142). Advantageously, because only a single tensile component is used, the precision in the set force necessary to decouple the two parts is improved. The coupling assembly is particularly suitable to joining two part of an oil pipeline in order to provide a safety, breakout function.

Abstract: Devices and methods for releasably securing components of a device having a sliding sleeve arrangement to prevent premature actuation due to vibration. In a currently preferred embodiment, standard elastomeric O-rings are used as shear members. The O-ring shear members reside within spaces formed between two slidable sleeve members. The O-rings are sheared cross-sectionally to allow the sleeve members to move axially with respect to one another. An exemplary coiled tubing shear release joint is described that incorporates a shear disconnect assembly which uses elastomeric O-rings as shear members. Multiple O-ring seals can be used as shear members to increase the shear value of the device. The use of O-rings as shear members helps prevent premature sliding of sleeve components in response to high vibration. Because the O-rings are resilient, they absorb vibration and do not shear during vibration, the connection between the two sleeve components will not be released prematurely.
