    Abstract: Assemblies can be disposed in a subterranean bore. An assembly can include a recessed portion in an inner wall and another recessed portion in an outer wall. The recessed portions can each be configured to have a cross-sectional thickness that is less than at least another part of the assembly. The assembly can provide a seal between an inner region defined by the assembly and an environment exterior to the assembly prior to a window being created in the recessed portion in the outer wall through which a branch wellbore can be formed. The recessed portion in the inner wall can guide a cutting tool toward the recessed portion in the outer wall.

    Abstract: A system for opening a window in a casing string (42) positioned in a wellbore (32). The system includes a hydraulic pressure intensifier (116) having a housing and a piston assembly with a differential piston area. The piston assembly is longitudinally shiftable relative to the housing and is initially secured relative thereto to prevent longitudinal movement therebetween. An anchor assembly (114) is operable to longitudinally secure the hydraulic pressure intensifier (116) within the casing string (42). A window opening tool (118) operably associated with the hydraulic pressure intensifier (116) is operably engagable with the casing string (42) such that when the anchor assembly (114) is longitudinally secured within the casing string (42) and the piston assembly is unsecured relative to the housing under hydrostatic pressure, longitudinal movement of the piston assembly transmits a force to the window opening tool (118), thereby opening the window in the casing string (42).

    Abstract translation: 一种用于打开位于井眼（32）中的套管柱（42）中的窗口的系统。 该系统包括具有壳体的液压增压器（116）和具有差动活塞面积的活塞组件。 活塞组件可以相对于壳体纵向移动并且最初相对于其固定以防止它们之间的纵向运动。 锚固组件（114）可操作以将液压增压器（116）纵向固定在套管柱（42）内。 与液压增压器（116）可操作地相关联的开窗工具（118）可与套管柱（42）可操作地接合，使得当锚固组件（114）纵向固定在套管柱（42）内时，活塞组件 在静水压力下相对于壳体不固定，活塞组件的纵向运动将力传递到窗口打开工具（118），从而打开套管柱（42）中的窗口。

    Abstract: In a telecommunications system employing modulated optical signals, a highway is formed from optical fibres and a source of coherent light or other electromagnetic radiation of an adjacent frequency band is connected to one end of the highway. One or more modulators are connected to the highway at intermediate positions along its length, the or each modulator being arranged to periodically vary the optical path length of the highway. A demodulator is connected to the other end of the highway.
