Patent CA-2218963-A1 (CA)
Title: Electrically driven actuator with failsafe feature
Inventor: TROTT DOUG
IPC: F16K31/04
Filed: 1997-10-15
Abstract: A valve actuator preferably driven by an electric motor is disclosed.  The valve actuator is useful with surface safety valves and uses power input from an electric motor to position the valve in its normal position.  A mechanism is provided to allow the valve to shift positions to a fallsafe position upon failure of electrical power to the motor connected to the actuator.  A screw drive is provided with the motor, with a latch mechanism holding a nut against rotation.  The nut can advance longitudinally upon rotation of the drive to move a valve stem.  Upon failure of electrical power, the latch mechanism releases the nut form a coupling in the actuator which is connected to the valve stem, and the main return springs in the actuator allow the nut to rotate with respect to the screw drive so that the valve can assume its failed position.  Normal applications allow the valve to fail closed; however, the valve can be configured so that failure results in opening of the valve if the application requires it.

Title: Sliding gate valve for a vessel containing molten metal
Inventor: WALTENSPUEHL ROLF
IPC: B22D41/38
Filed: 1998-04-23
Abstract: A sliding gate valve for a vessel containing molten metal has a push rod (27), which is associated with a slider unit longitudinally guided in a slider housing, which slider unit may be connected by means of a coupling (40) with a drive rod (32) of a linear actuator (30), a mounting (28) for receiving the linear actuator (30) being provided on the slider housing. The coupling (40) is so constructed that it automatically couples, when the linear actuator (30) is slidinto the mounting (28), by virtue of movement of the drive rod (32) towards the slider unit (25) and this coupling (40) automatically decouples when the linear actuator (30) is removed from the mounting (28) transversely to the direction ofmovement of the drive rod (32). The one coupling portion of the coupling (40) has claw elements (41,42) which are spread outwardly during the coupling process along guide surfaces (43') on the other coupling portion (43) until theyautomatically snap in at it and engage around it in a form-locking manner.

Title: Optically amplified wdm transmission system
Inventor: EPWORTH RICHARD EDWARD
IPC: H04B10/17
Filed: 1998-05-26
Abstract: The problem of gain tilt in an optically amplified WDM system is avoided by using SBS (Stimulated Brillouin Scattering) to limit the power levels of the individual WDM channels at the outputs of at least selected amplifiers in the transmission path. The SBS limits the power by the creation of a dynamic amplitude Bragg reflective grating. Alternative mode of creating such gratings are also described, one relying upon the Kerr effect, and another relying on creating a thermal grating in a medium, such as a liquid crystal that exhibits a refractive index that is strongly temperature sensitive.
