Abstract: An Air conditioning and potable water generating system in which a cooling element condenses water from atmospheric air is operable two switch between an air conditioning mode, in which cooled atmospheric air from which water has been extracted is supplied to a building's interior environment, and a water generating mode, in which communication of such supply air into the building interior is closed off. The system can thus be operated to collect water regardless of whether cooling of the building interior is required at a particular point in time. Use of the same cooling element in each mode provides and use of return air from the building to mix with incoming fresh air and cool the heat dissipating element of the cooling system make for efficient operation. Controls of the system are operable to change a mixture ratio of the fresh atmospheric air and circulating return air.

Abstract: Apparatus and method for working of a workpiece use the expansion of water in a container during the freezing process to drive a piston against a workpiece that is positioned to at least partially overlie a cross-sectional area of a hollow interior of the container. Use of a piston with a tapered working end focuses the resulting force against a small area of the workpiece in order to produce a bend in the workpiece at the point of application. In environments where conventional bending tools are not available, the apparatus can be used to perform bending or other operations on workpieces of varying materials.
