Disclosed is an optical fiber cable that includes optical fibers and a deformable coupling element enclosed within a buffer tube. The coupling element is formed from a deformable yet substantially incompressible material and features a number of raised members projecting toward the optical fibers. The design of the coupling element layer permits coupling of the optical fibers to the buffer tube without the use of a compressive cushioning layer. This arrangement distributes the compressive force applied to discrete points along the outer perimeter of the optical fiber element.

An apparatus to protect the mounting area of casing when subsequently attaching a tubular is disclosed. A sleeve that defines a sealed cavity having a loose incompressible material inside covers the mounting location on the casing. The cementing of the casing takes place through the sleeve. After the cementing, the sleeve is drilled out and the incompressible material is removed to the surface with the drill cuttings. A tubular is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. At the end of expansion, the run in shoe on the tubular is retrieved.

An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. After expansion a cement retainer positioned at the bottom of the expanded liner and the sliding sleeve located either above the mounting location of the liner in the casing shoe or in the liner below the mounted top section allow cement to be delivered outside the expanded liner and the displaced wellbore fluid to return into the casing through so that the liner can be cemented. The cement retainer can be delivered with either the liner or the expansion tools to allow expansion and cementing in a single trip. A shifting tool can be run on the expansion string to actuate the sliding sleeve and if necessary to allow for cement to be pumped from the drill string into the annulus through the sliding sleeve. The cement retainer can be milled out in a separate trip.

The invention relates to a direct tensile test jig of an incompressible material, and belongs to the field of building material test devices. The direct tensile test jig is composed of fixed joints, switch chucks, connection boards, bolts and metal rods, solves a problem of test incompletion caused by data distortion even shedding because of the sliding of a test piece at the clamping end in the direct tensile test process of a present incompressible material, can reliably realize the direct tensile test of the incompressible material to accurately obtain the mechanical property parameters of the material, and has a certain application prospect.

The invention relates to a pressure-measuring member (12) comprising: a pressure-measuring surface (106) functionally connected to a test body (96); a sealed pressure-measuring housing (100) in which the test body (96) is placed, whereby the pressure-measuring surface (106) is borne by a deformable wall (104) of the sealed pressure-measuring housing (100) that extends at a distance from the test body and the housing (100) defines an internal space (E); means (110) for transmitting the pressure between the pressure-measuring surface (106) and the test body (96), comprising a substantially incompressible material (136) that occupies all of the internal space (E); and energy storage means (101) and means (99) for processing the pressure detected by the test body (96), provided in the sealed housing (100).

A vibration isolator suitable for isolating and / or dampening vibrations generated in a vibrating machinery component such as a motor or pump so as to minimise the unwanted effects (such as audible secondary sounds) of those vibrations. The isolator may be installed in a home appliance such as a laundry washing machine and may be a separate, unitary component installed between a motor / pump and the structure of the laundry machine or may be installed between a mounting bracket of the motor / pump and the laundry machine. Alternatively, the isolator may be integrally formed with a pump / motor mounting bracket, on upper and / or lower surfaces of a mounting flange. The isolator is preferably formed from a substantially incompressible material and in one preferred embodiment has a washer-like form with a central opening at least partially surrounded by a tubular ridge with a plurality of radial projections extending outwardly and / or inwardly from outer / inner surface(s) of the tubular ridge.
