Abstract: A solid state electrolyte and method of preparation is provided. The solid state electrolyte includes a plasticized polymer matrix with non-dissolved salt crystals embedded in the polymer matrix and wherein the non-dissolved crystals are suitable for dissolving ions in the plasticized polymer. The method of preparation includes dissolving a plasticizer and a polymer matrix in an organic solvent to obtain a plasticized polymer matrix; and mixing the salt crystals with the plasticized polymer matrix, wherein the weight ratio of salt crystals versus plasticizer and polymer matrix and organic solvent is above saturation concentration such that non-dissolved salt crystals are embedded in the plasticized polymer matrix.

Abstract: A power actuated tool for driving a fastener such as a pin into a substrate such as steel or concrete comprises a driving piston (6) which is driven forwardly within the barrel (4) of the tool upon firing and is automatically reset in response to cocking of the tool prior to the subsequent firing. Resetting of the piston takes place by thrusting the piston (6) rearwardly during cocking by means of a spring-loaded gripper device (14) energized during cocking.
