Abstract: The solar evaporator is comprised of a parabolic dish structure and the evaporator located just outside of the focal point. The refrigerant, coming from the heat pump, circulates through the evaporator. After having been heated up by the concentrated solar heat, the refrigerant is routed to the heat pump which compresses the refrigerant so as to extract the maximum amount of heat collected. The goal is to continuously maximize the temperature differential at the receiving coil by keeping the refrigerant at the lowest temperature possible in order to maximize heat gains at the evaporator. Multiple parabolic dishes can work together wherein they are connected in parallel to the header. A sun tracking mechanism ensures that the dishes are always pointing towards the sun. The extract heat can be used for multiple purposes.

Abstract: A spring for windshield wiper assemblies is comprised of a resilient rod having a plurality of sections adapted to removably attach to a windshield wiper assembly of a vehicle. The rod includes a first hook section at one end section thereof; a second hook section located at an opposite end section thereof. An intermediate coiled section attached to and located adjacent the first hook section, and a connector section defining an axis along its length and connected between the intermediate coiled section and the second hook section.

Abstract: The spring has an intermediate helical portion with a U-shaped open hook at each end. The helical portion is disposed in the region of the pivot of the wiper support arm to the base part which holds the support arm. One hook wraps around the wiper support arm, passing over and hooking underneath the same and the other hook wraps around the base part, passing underneath and hooking on the top of said base part. The spring greatly increases the wiper pressure on the windshield. The spring remains properly hooked even when the support arm is pivoted away from the windshield.

Abstract: A shell composed of semi-rigid material which covers the top, the front, the sides and the bottom of the gloved hand of a skier when clenched on a ski pole hand-grip and which has a larger volume than the gloved hand when clenched on the hand-grip, so that the gloved hand does not come in contact with the shell. This shell being metallized inside with reflective material. The top part rises above the top of the hand-grip and is kept spaced from it through a spacer and is attached by way of a screw. The bottom part has a slanted surface toward the rear and the bottom and has a hole in it, which receives the ski pole, in order to attach the bottom part of the shell to the ski pole.
