Wearable personal cooling and hydration system
InactiveUS20060191049A1Maximum comfortMinimal contaminationChemical protectionGarment special featuresHeat transfer fluidEngineering
A heat transfer fluid pathway is provided driven by a pump which feeds the heat transfer fluid through a vest and cap or other heat transfer garment, where the heat transfer fluid draws heat away from the body of the wearer. A drinkable heat sink material is located within a removable cartridge located within a heat exchange pouch. The heat transfer fluid passes from the heat transfer garment to the heat exchange pouch where heat drawn from the wearer is transferred to the heat sink material within the cartridge. A temperature control valve is provided along with a bypass line so that an adjustable amount of the heat transfer fluid is routed to the heat exchange pouch for temperature control. A supply of elevated pressure air is optionally provided to maintain optimal contact for efficient heat transfer within the heat exchange garment and the heat exchange pouch.

Shale oil and gas fracturing fluids containing additives of low environmental impact
InactiveUS20140090850A1Less harmfulLess harmful to the environmentFluid removalFlushingParticulatesFracturing fluid
The present invention relates to improved chemical additives for use in hydraulic fracturing fluids for the recovery of oil or natural gas entrained in deep-layer shale formations. Many chemical agents currently in use in such water / sand (or other proppants) mixtures could pose human and animal health risks if these chemicals migrate from the shale beds into the environment contaminating the water table, rivers, streams and lakes. The fracturing fluid chemical additives of this invention are designed to be retained or anchored in or near the deep shale layers and are prevented, or greatly delayed from upward migration. Specifically, many chemical additives required for proper fracturing fluid performance can be chemically bonded to inert particulate materials before incorporation into said fluids. The fracturing fluid chemical additives are able to perform their function in the shale fracturing process, and then become nearly permanently trapped in the shale layers protecting the environment above.

Date Apr. 24, 1997The present invention provides a method for clone-multiplication of a Paphiopedilum wherein a scape terminal bud or an axillary shoot, whose surface has been sterilized, or an aseptic shoot obtained by an aseptic cultivation, of a Paphiopedilum stock, are cut into cross-sectional pieces which are then cultivated in a medium containing a plant hormone. By cutting an aseptic shoot containing a number of axillary buds into cross-sectional pieces and cultivating, a multishoot formation is feasible. Also by employing a liquid medium containing a solid support such as a rockwool or a paper filter in the culture, the plant death due to browning of tissues can effectively be prevented. In addition, by optimizing the method for sterilizing the buds before blooming, the medium composition and the culture condition, a large scale production of Paphiopedilums by means of a clone multiplication technology becomes feasible.

Method of Gallium Nitride growth over metallic substrate using Vapor Phase Epitaxy
InactiveUS20110117376A1Advanced technologyAbsence of scratch and stepPolycrystalline material growthFrom chemically reactive gasesVapour phase epitaxyGas phase
The current invention introduces a method of crystal film's growth of Gallium Nitride and related alloys over a novel class of the substrates using Vapor Phase Epitaxy technique. This said novel class of the substrates comprises single crystal lattice matched, partially matched or mismatched metallic substrates. The use of such substrates provides exceptional thermal conductivity and application flexibility, since they can be easily removed or patterned by chemical etching for the purposes of additional contact formation, electromagnetic radiation extraction, packaging or other purposes suggested or discovered by the skilled artisan. In particular, if patterned, the remaining portions of the said substrates can be utilized as contacts to the semiconductor layers grown on them. In addition, the said metallic substrates are significantly more cost effective than most of the conventional substrates. The use of Vapor Phase Epitaxy allows growing the epitaxial layers with different and / or variable alloy composition, as well as heterostructures and superlattices.
