We see from your search that you're looking for information on the term "Hydraulic Actuators",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release System reduces the dangers of drilling at sea from
Moog Controls, which we summarised at the time by saying "As the platform moves up and down with the heave of the sea surface, hydraulic oil passes backwards and forwards from actuator to accumulator, keeping the platform stationary relative to the
seabed".
A few weeks before,
we featured the news release Converting from hydraulics to an electric actuator from
Micromech: "Micromech Technical Director Stirling Morley debunks some of the myths about electric linear actuators that have slowed their adoption in many applications".
In August 2007, we covered the news from Orange Instruments
concerning its GS400, AP51 and PB90 positioners
- take a look at Company offers new actuator options
which says: "Orange Instruments positioners use analogue signal conversion, comparison of desired and actual position and the operation of the actuator drive to bring the actuator to a stable position".
Take a look also at the news release from MiniTec UK, Profiles allow easy construction,
as well as Actuators chosen for gas projects from Rotork Controls,
and Hydraulic controller sinks special effects from Moog Controls.
