摘要： Fibre locating apparatus to facilitate alignment of an optical fibre comprises accurately aligned silica blocks (1,2 and 3) respectively providing a fibre guiding `V` groove (4), a perpendicular facing surface (10) and a mounting (7) for a mirror or other planar signal receiving surface. The apparatus allows rapid realignment of fibre ends when optical systems (e.g. fibre lasers) require reconfiguration.

摘要： A device for locking a piston rod of a hydraulic piston and cylinder assembly in an extended condition. The locking device is placed in interposed relation to a hydraulic cylinder and an opposing bearing point to prevent retraction of the piston rod. The device has a split sleeve configuration to facilitate mounting the locking device in encircling relating to the piston rod including opposed longitudinally extending edges that are locked to one another via a locking means. The locking means of the device is partially enclosed by a lock protecting housing to protect the locking device from being removed by unauthorized persons. The device is durable, easy to install and remove, and adaptable to a variety of hydraulic piston and cylinder assemblies.

摘要： An 850 nm laser and/or amplifier comprises a single mode fluoro-zirconate optical fibre (20) doped with Er.sup.3+. CW operation of the normally self-terminating lasing transition .sup.4 S.sub.3/2 to .sup.4 I.sub.13/2 is achieved by applying excitation energy at 801 nm which both maintains a population inversion between the lasing levels and also populates the upper lasing level by a two-stage process of excitation to the .sup.4 I.sub.9/12 level from the .sup.4 I.sub.15/2 ground state and then to .sup.2 H.sub.9/2 level by ESA.

摘要： A device for locking a piston rod of a hydraulic piston and cylinder assembly in an extended condition so that mobile construction equipment or other heavy machinery cannot be driven from a job site. The locking device is placed in ensleeving relation to an extended piston rod between a proximal hydraulic cylinder and a distal bearing point to prevent retraction of the piston rod. The device has a hollow sleeve configuration formed of confronting first and second sleeve parts that are hingedly connected to one another. A first lock secures the first and second sleeve members to one another along a longitudinally extending parting line. A second lock is opposed to the first lock and prevents hinged movement of the first and second sleeve parts relative to one another even if the first lock is defeated. The device is adaptable to a variety of hydraulic piston and cylinder assemblies.
