  • Patent number: 9915478
    Abstract: A system and method are provided for storing electric energy in the form of thermal energy. A thermoelectric energy storage system includes a working fluid circuit for circulating a working fluid through a heat exchanger, and a thermal storage medium circuit for circulating a thermal storage medium. The thermal storage medium circuit includes at least one hot storage tank, an intermediate temperature storage tank, and a cold storage tank connected together via the heat exchanger. A proportion of the storage medium is redirected to or from the intermediate storage tank from or to the hot or cold storage tank, joining another proportion which flows directly between the cold and hot storage tank.

  • Patent number: 9915444
    Abstract: Our invention consists of two separate and discrete families of polymers, e.g. thermosetting Fiberglass Reinforced Plastics (“FRP”) and thermoplastics. Both are used as the materials of construction to fabricate solar thermal collectors. These families have the same general configuration and are based upon the same principles. Both families are used in a form that some of the walls of the collector are translucent. Both families incorporate a passage through which the thermal fluid flows. Both families make use of dyes to absorb energy from the sun in the fluid and the collector walls. Each of the families makes use of improved collector configurations and designs and special operating approaches. Each family can serve different markets for different solar thermal collectors. In particular, FRP stands alone as an emerging new category of materials for a broad range of applications including everything from novel solar thermal collectors to exotic airplanes.

  • Patent number: 9907461
    Abstract: A system and associated method are used for warming an endoscope, laparoscope, or other such instrument to minimize fogging. A flexible pad has a length, a width and a periphery for wrapping around the instrument. An activation disc and a mixture of water and sodium acetate are used to generate heat through an exothermic reaction initiated through manual manipulation of the disc. The disc may be exposed in a flexible tab in fluid communication with the pad. A housing includes an end bore to receive the instrument such that the instrument is surrounded by the folded or rolled pad within the housing. The housing may further include a slit or narrow opening enabling the tab and activation disc to extend therethrough and outside the housing for activation.

  • Patent number: 9885226
    Abstract: In one aspect, a method of extracting heat from a downhole device is disclosed, which method, in one non-limiting embodiment, may include: providing a heat exchange fluid that includes a base fluid and core-shell nanoparticles therein; circulating the heat exchange fluid in the downhole device proximate to a heat-generating element of the downhole to cause the core of the core-shell nanoparticles to melt to extract heat from the downhole device and then enabling the heat exchange fluid to cool down to cause the core of the core shell nanoparticles to solidify for recirculation of the heat exchange fluid proximate to the heat-generating element.

  • Patent number: 9867232
    Abstract: A heating element for heating gases to high temperatures includes at least one tube arranged for the flow of gas to be heated and an electrical heating wire in the tube, which transfers heat to the gas flowing past. A process heater and a corresponding heating element are provided to permit generation of gas temperatures up to 1000° C. or above and having a lifespan 10 times longer than conventional heating coils. The heating wire is formed as a heating rod extending along the tube axis, whose maximum clear distance to the inner wall of the tube does not exceed a value of 10 mm over at least 80% of the circumference and/or at least 80% of the overlapping length of the tube and heating rod.

  • Patent number: 9813012
    Abstract: A rail-less roof mounting system for installing photovoltaic (PV) modules on a roof structure comprises a base mount assembly that engages with a clamp assembly and attaches to the roof structure. The base mount assembly comprises a base member having a waterproof means, a block slider, a top slider and a covering means. An elevated seal portion of a block slider includes a borehole to receive the waterproof means. A vertical engaging portion of the block slider is attached with a sliding seal member of the top slider. The clamp assembly includes a clamp member and a plate member and the clamp member is attached with a track of the top slider. The clamp member interlocks the PV modules to provide a corner-to-corner coupling arrangement, which enables the connection of PV module corners to adjacent PV module corners by sandwiching above and beneath frame members of the PV modules.
