Abstract:
A microwavable thermal energy storage material is provided which includes a mixture of a phase change material and silica, and a carbon black additive in the form of a conformable dry powder of phase change material/silica/carbon black, or solid pellets, films, fibers, moldings or strands of phase change material/high density polyethylene/ethylene-vinyl acetate/silica/carbon black which allows the phase change material to be rapidly heated in a microwave oven. The carbon black additive, which is preferably an electrically conductive carbon black, may be added in low concentrations of from 0.5 to 15% by weight, and may be used to tailor the heating times of the phase change material as desired. The microwavable thermal energy storage material can be used in food serving applications such as tableware items or pizza warmers, and in medical wraps and garments.
Abstract:
A method and apparatus is disclosed for the complete analysis of used oils, lubricants, and fluids. The method can monitor antioxidant depletion, oxidation initiators buildup, product buildup, or liquid contamination or combinations thereof. The method can be performed either on-line or off-line but is preferably an on-line system, either a built-in system or a dip-stick type system, having a working microelectrode, a reference electrode, and an auxiliary electrode. A sample is contacted by the electrodes and subjected to cyclic voltammetric analysis, whereby a varying electric current is produced within the sample. The current is measured and recorded, and the conductance is measured. The remaining useful life of the oil, lubricant, or fluid is then determined from the wave heights of the oxidation and reduction peaks, and the contamination is determined from the conductance.
Abstract:
A composite useful in thermal energy storage, said composite being formed of a polyethylene matrix having a straight chain alkyl hydrocarbon incorporated therein, said polyethylene being crosslinked to such a degree that said polyethylene matrix is form stable and said polyethylene matrix is capable of absorbing at least 10% by weight of said straight chain alkyl hydrocarbon; the composite is useful in forming pellets or sheets having thermal energy storage characteristics.
