    摘要： A dual linear actuator for allowing a tool to perform multiple actions either simultaneously or independently of one another. The dual linear actuator includes an outer tubular housing having open first and second ends and also having a bore extending therethrough; and also includes an inner tubular housing being securely disposed in the bore of the outer tubular housing and having open first and second ends and also having a bore extending therethrough; and further includes a first cap being removably attached to the first ends of the outer and inner tubular housings; and also includes a second cap having a side wall and being removably attached to the second end of the inner tubular housing; and further includes a third cap having a side wall and being removably attached to the second end of the outer tubular housing; and also includes a first piston assembly including a tubular piston being movably disposed in the bore of the outer tubular housing; and further includes a second piston assembly including a piston member being movably disposed in the bore of the inner tubular housing.

    摘要： An insulating system is described that incorporates a cellulosic material which is impregnated with a nitrogen content no less than 0.2% by weight and a overall density not greater than 0.9 gm/cm.sup.3. This cellulosic material when impregnated by a dielectric liquid such as transformer oil, exhibits a more uniform electrical stress distribution than papers having a density greater than 0.9 gm/cm.sup.3. The insulating system thereformed is particularly useful for application in low stress areas such as the layer insulation in a distribution class transformer.
