  • Patent number: 10266741
    Abstract: An apparatus and method for the addition of alcohol dehydrogenase (ADH) enzyme inhibitors to existing engine cooling systems to reduce or eliminate the coolant toxicity without the need to completely drain and replace the entire engine coolant. In addition, the present invention provides an apparatus and method for treatment of otherwise toxic coolants removed from engine cooling systems that are targeted for disposal and release into the environment and thereby reduce or eliminate the condition of creating relatively large amounts of toxic waste during routine maintenance and repairs.

  • Patent number: 8394287
    Abstract: A non-aqueous, reduced toxicity polyhydric alcohol based heat transfer fluid is provided comprised of at least one polyhydric alcohol that acts as an ADH enzyme inhibitor, such as for example propylene glycol, thereby reducing the toxicity of ethylene glycol if ethylene glycol. The heat transfer fluid may also include corrosion inhibitors that are soluble in the polyhydric alcohols used for the heat transfer fluid. The heat transfer fluid may be used as a coolant in internal combustion engines such as automobile engines, a coolant for cooling electrical or electronic components, as a heat transfer fluid for solar energy heating systems, or a heat transfer fluid for maintaining temperatures in industrial processes. A low toxicity preparation fluid for absorbing water from heat exchange systems prior to installation of the heat transfer fluid is also provided that is comprised of ethylene glycol and at least one polyhydric alcohol, preferably propylene glycol, that acts as an ADH enzyme inhibitor.

  • Patent number: 8206607
    Abstract: A method for cooling an internal combustion engine using a reduced toxicity, ethylene glycol and water based heat transfer fluid is provided. A heat transfer fluid is formulated comprising water and a glycol component consisting of ethylene glycol and either propylene glycol or glycerol. Propylene glycol may be provided in an amount between 5% to less than 30% of the total weight of the glycol component. Glycerol may be provided in an amount between 5% to 20% of the total weight of the glycol component. The glycol component is less toxic than 10,000 mg/kg on an acute LD50(rat) oral toxicity basis. The water comprises between 40% and 70% by weight of the total weight of the heat transfer fluid. The cooling system of the internal combustion engine is substantially filled with the heat transfer fluid such that the heat transfer fluid absorbs heat that is produced by the internal combustion engine and releases the absorbed heat to the atmosphere.

  • Patent number: 7957314
    Abstract: A method is provided in one example embodiment and includes requesting real-time transfer protocol (RTP) quality metrics to be generated by a network for a specific flow in the network. The method also includes recording the RTP quality metrics and reporting the metrics as accounting data associated with the flow. In more specific embodiments, the accounting data includes a correlator with application level accounting and the accounting data is used for quality monitoring and troubleshooting on a per-subscriber basis, on a per-flow basis, or on a per-call basis. An application function can request RTP quality monitoring with a trigger that identifies if a quality parameter reaches a certain threshold.
