Abstract: An exemplary embodiment includes a heated blade for cutting a synthetic line or rope as well as heated sealing cylinders for sealing the cut or raw ends against raveling. The cutter can accommodate lines of a variety of diameters. The cutter is powered by a rechargeable battery and is portable and safe for use in a marine environment. Other embodiments seal the raw ends by shrinking a heat-shrinkable tubing over the raw ends.

Abstract: A self-adjusting, self-storing rollaway inside storm window for use at conventional windows, which can be quickly put up and taken down as desired, includes a transparent flexible panel mounted on and constantly tensioned at the top end by a spring-retracting roller in the manner of a window shade and deployable over a self-adjusting spring biased extension rod securable between the sides of a window frame at the top, and at the bottom loop-affixed around a similar self-adjusting spring biased extension rod also securable between the sides of the window frame; a special shock cord deployed along each side of the panel between the upper and lower self-adjusting spring loaded rods biases the vertical edges of the panel in a direction for sealing against the window frame structure; intermediate disconnects are provided in the shock cord, and special ends on the self adjusting spring loaded rods adapt them for securance to window frame structures of different types.
