  • Patent number: 10894930
    Abstract: A traction fluid comprising a blend of 2,3-dicyclohexyl-2,3-dimethylbutane (HAD) and 2,3-dicyclohexyl-2,3-dimethylbutane (iso-HAD) is found to have a lower viscosity at low temperatures when compared to a traction fluid having only HAD or only iso-HAD as a base fluid with no compromise to traction coefficient. The traction fluid may comprise additives. The traction fluid usually comprises HAD:isoHAD between about 8:1 to about 1:3. Further, the HAD:iso-HAD traction fluid blend is produced by a method of simultaneous co-production of hydrogenated HAD and hydrogenated iso-HAD from an alpha styrene dimer and an iso-HAD precursor with a yield of about 90% in a method that does not require a purification step.

  • Patent number: 10352011
    Abstract: A method for increasing moisture retention in a soil includes applying an effective amount of an effective humectant composition to the soil. The effective humectant composition is identified by determining the average moisture content of the soil for the humectant compositions applied at a minimum humectant concentration level, a maximum humectant concentration level, and at a first concentration level between the minimum and the maximum humectant concentration level. An average slope curve is generated by plotting the determined average moisture content of the soil for each applied humectant concentration levels from the minimum humectant concentration level to the maximum humectant concentration level. An effective humectant composition is determined when the generated average slope curve provides an increasing average moisture content along the entirety of a length of the generated average slope curve and when the generated average slope curve has a p value of 0.05 or less.

Further, the disclosed concept relates to methods of towering the internal temperature of an electrically resistive, thermally conductive electrical switching apparatus by forming the internals of the apparatus, e.g., circuit breakers, and/or the enclosure from the composition of the disclosed concept.

  • Publication number: 20150034858
    Abstract: A thermally conductive polymer composition comprising (1) a polymer material, and (2) a thermally conductive filler. The thermally conductive filler can be boron nitride. The thermally conductive polymer composition can be used in a molding operation to form a molded article and can reduce the molding cycle time of a molding process. In one embodiment, increasing the thermal conductivity of a polymer material (as compared to the thermal conductivity of the material in the absence of a thermally conductive filler) increases the thermal diffusivity and reduces the cooling time of the article. The present invention also provides methods of forming molded articles from such compositions.

The gelling agent may be a high molecular weight styrene-ethylene-butylene-styrene (SEBS) triblock copolymer with a styrene:rubber ratio of about 30:70 to 33:67% by weight. To form the gel, the phase-change material and the gelling agent may be mixed at an elevated temperature relative to room temperature to partially, but not completely, dissolve the gelling agent. The mixture may then be cooled to room temperature. Alternatively, the phase-change material and the gelling agent may be mixed at room temperature, and the mixture may then be heated to form a viscoelastic liquid, which is then cooled to room temperature. The invention is also directed at a method of preparing the gel, a thermal exchange implement including the gel, and a method of preparing the thermal exchange implement.
