  • Patent number: 9732735
    Abstract: An apparatus, system, and method for raising water is provided. The apparatus includes at least one container movable between at least a descended position and a ascended position within a body of water. A non-water-permeable membrane is positioned within the at least one container, wherein the membrane is movable within an interior compartment of the at least one container to separate the interior compartment into at least a first and a second portion. At least one vent structure is within a wall of the at least one container, wherein movement of the membrane controls a flow of water through the at least one vent structure and into at least one of the first and second portions.

  • Patent number: 9132412
    Abstract: An adsorption structure is described that includes at least one adsorbent member formed of an adsorbent material and at least one porous member provided in contact with a portion of the adsorbent member to allow gas to enter and exit the portion of the adsorbent member. Such adsorption structure is usefully employed in adsorbent-based refrigeration systems. A method also is described for producing an adsorbent material, in which a first polymeric material provided having a first density and a second polymeric material is provided having a second density, in which the second polymeric material is in contact with the first polymeric material to form a structure. The structure is pyrolyzed to form a porous adsorbent material including a first region corresponding to the first polymeric material and a second region corresponding to the second polymeric material, in which at least one of the pore sizes and the pore distribution differs between the first region and the second region.

  • Publication number: 20140174010
    Abstract: A building has walls built from blocks with cavities. Roofs and floors are formed from joists extending between walls. Each joist has a vertical plate, an angle piece located on each side of the vertical plate and end plates. The end plates bear on the wall blocks. Pins extend from the end plates into cavities of the wall blocks. Bond beams can be positioned on walls parallel to the joist. Horizontal blocks are laid across the joists to form a roof or floor.

  • Publication number: 20140059965
    Abstract: The invention is to make a rectangular block that will be used in a construction system based on the combined use of a double locking mortar-less block designed that locks together. The double locking mortar-less block of rectangular configuration with two end cavities of equal size and ears on the middle web. Each ear is the same dimension as the grooves in the internal faces of the end and sidewalls of each cavity. Each groove being positioned, shaped and dimensioned so that an ear and groove of adjacent blocks can be interlocked. The contour face of the block is contoured along axes perpendicular to the top and bottom faces of the block and the block face has protruding and receding portions. The respective protruding and receding portions interlock so that the block is adapted to form a rigid structure.
