Abstract: The present invention is for a safety guard rail system having folding guard rails designed to be raised or lowered at their base by a single individual from an acceptable safe distance from the edge of a precipice, such as the edge of a building roof. A sliding sleeve hinge lock locks each folding rail in an erect position and can be remotely unlocked for folding the rail. An elongated grappling tool has a hook-like end for grabbing the sliding sleeve hinge lock handle for locking and unlocking the hinge lock from a distance when erecting or folding a guard rail.

Abstract: Synthetic fiber that are capable of spontaneously transporting water on their surface satisfy the equation(1-X cos .theta..sub.a)<0,wherein.theta..sub.a is the advancing contact angle of water measured on a flat film made from the same material as the fiber and having the same surface treatment, if any,X is a shape factor of the fiber cross-section that satisfies the following equation ##EQU1## wherein P.sub.w is the wetted perimeter of the fiber and r is the radius of the circumscribed circle circumscribing the fiber cross-section and D is the minor axis dimensionacross the fiber cross-section, and wherein the uphill flux value of said fiber is from 2 to 60 cc/g/hr when measured from a reservoir of synthetic urine test fluid along a 20 cm long ramp to an absorbant on an attached platform at 10 cm height.

Abstract: Spinnerets are used to make synthetic fibers having the unique property of spontaneously transporting water on their surface. The synthetic fibers satisfy the equation(1-X cos .theta..sub.a)<0,wherein.theta..sub.a is the advancing contact angle of water measured on a flat film made from the same material as the fiber and having the same surface treatment, if any,X is a shape factor of the fiber cross-section that satisfies the following equation ##EQU1## wherein P.sub.w is the wetted perimeter of the fiber and r is the radius of the circumscribed circle circumscribing the fiber cross-section and D is the minor axis dimension across the fiber cross-section, and wherein the uphill flux value of said fiber is from 2 to 60 cc/g/hr when measured from a reservoir of synthetic urine test fluid along a 20 cm long ramp to an absorbent on an attached platform at 10 cm height.
