  • Solar and heat pump powered electric forced hot air hydronic furnace
    Publication number: 20090000611
    Abstract: A furnace in combination with a heat pump and solar panels for providing domestic hot water and forced hot or cooled air utilizing heat pump achieved efficiency levels in an on-demand and unlimited domestic hot water, heating and air conditioning system. In heating mode, recycled air acquires heat from the heat pump's condenser coil and transfers this heat to the on-demand hot water.

  • Composition for the detection of electrophilic gases and methods of use thereof
    Patent number: 5951909
    Abstract: There is provided a method for the detection of leaks of an electrophilic gas from a system, such as chlorodifluoromethane or carbon dioxide, which comprises applying to an exterior surface of the system a gel consisting essentially of a Lewis base capable of removing a proton from the gas or reacting therewith in a similar electrophilic manner; a dye capable of visibly indicating a color change on protonation or deprotonation; a solvent for the dye, the base and the gas; and a rheology modifier capable of producing a non-newtonian gel of all of these components which is sufficiently translucent to permit visual detection of change of color of the dye and of sufficient pseudoplasticity/thixotropy to provide adhesion to vertical and horizontal surfaces.
