Принадлежит: National Chung Shan Institute of Science and Technology NCSIST

A thermo-interface material composite uses a thermo-interface material containing silver nanowires. The silver nanowires have high aspect ratios, high thermo-conductivity coefficients and good anti-oxidation capabilities. Hence, an amount of silver nanowires can be added fewer than that of a traditional metal or ceramic powder. In this way, defects on device surface can be speckled during a dispersal process for improving adhesion between devices. Thus, a thermo-interface material is fabricated to obtain a high thermo-conductivity coefficient for further forming a thermo-channel.

This invention covers a formulation providing protection against corrosion in liquid and vapor phase. Such formulations are used in applications where engine parts or fuel cell systems are subjected to a “running-in” or “hot-test” prior to final assembly or storage. The invention includes a concentrate as well as a dilute solution. The synergistic combination of inorganic ammonium derivatives in combination with monocarboxylic or dicarboxylic acids increases the period of protection. This enables storage for a longer period when the engine parts are shipped or stored prior to assembling. The use of the described invention pre-conditions the metal surface and provides protection even if afterwards the liquid is almost completely removed.

Novel, Safe and Efficient Thermal Transfer Media for Processing of Food and Drink Products

A family of novel thermal processing and transfer media has been designed for optimized food and drink processing. These media composed solely of compounds approved to contact food, are essentially free of water, do not change state at any point in the process, remain corrosion-free throughout their useable life. While in combination with novel processing apparatus and methodologies, food and drink products requiring any heating, holding or cooling can be processed within the same equipment configurations essentially with no/minimal need for additional pressurization, the use of unheated modified atmospheres, in conjunction with these novel media, can be used to change or control the atmospheres within containers, especially polymer based containers, at specific locations within the processing cycle. It further relates to using different media compositions for each processing stage modified to optimize the thermal conductivity and thermal diffusivity properties of the foodstuff being processed, minimizing costs and maximizing quality.

The chemical reactions modulation of temperature and dissipate heat through using phase change materials (PCM). Hydration of a mixture composed of encapsulated and/or non-encapsulated oxides such as calcium oxide and/or magnesium oxide and dehydrated and/or hydrated zeolite coupled with control of pH of mixture through compounds such as Citric acid, or combination exothermic mixes, such as Cao and Mg—Fe, provide sustained heat release and heat retention tailored by addition of PCMs. The modulation may include timed/controlled release from encapsulated reactants and may include particles with tailored size distribution and different burn characteristics. The phase change materials used include organics (paraffins, non paraffins and fatty acids) and inorganics (salt hydrates). The selection of PCM is based on compatibility with the reacting mix, added reacting aqueous medium, and the desired temperature the system is to be held constant or temperature range it is desired to be modulated.

Self-heating containers comprise a reaction chamber and a heating chamber. The heating chamber is sized to contain a substance to be heated. The reaction chamber contains reactants which, when contacted, exothermically react. The reaction chamber is divided into a first compartment and a second compartment with a barrier therebetween. The barrier comprises a first barrier portion and a second barrier portion. The first barrier portion is attached to a reaction chamber wall and has an opening sized to allow reactants to flow through from one compartment to the other. The second barrier portion is attached to the first barrier portion to close the opening. The barrier can be opened by moving an actuator into engagement with the second barrier portion to dislodge the second barrier portion from the first barrier portion and thereby open the barrier.

Surface treatment of beverage containers to keep the beverage cool

Номер: US20140026595A1
Автор: Barbara Hildegard Pause
Принадлежит: Individual

The invention pertains to a method suitable to reduce the heat transfer into a beverage container in order to keep the beverage cool over an extended period of time after taken from the refrigerator. The method is based on a surface treatment of the beverage container which comprises a binder in which phase change material is incorporated. By absorbing latent heat without a temperature increase, the phase change material creates a thermal barrier against heat penetration. The binder with the phase change material contained wherein is applied to the surface of the beverage container, for instance, by spray coating. The coating layer covers most of the container's surface. A second coating layer which does not contain phase change material is applied on top of the first coating layer in order to provide protection against mechanical stress during high speed filling and packaging.
