Edward A. Reid, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5077986
    Abstract: An improvement in an absorption refrigeration and/or heating system including apparatus (157) to convert the pressure energy and/or phase change energy in the solution and/or refrigerant of the absorption system into mechanical energy, with additional apparatus to replace or supplement the externally supplied mechanical energy motive device (152) in the system with the converted mechanical energy. The system includes a first positive displacement pump (98) for conveying the absorbent solution from the absorber to the generator with first positive displacement apparatus (98) driven by a motive device (152) that is activated by the externally supplied energy. A second pump (158) is provided that is driven by the system pressure energy. Each of the pumping apparatus is being independently driven and connected to the other only by fluid connection.

  • Patent number: 4742693
    Abstract: This invention relates to a cooling and heating system which operates on the absorption and phase change heat exchange principle. More particularly it relates to a continuous heat actuated, air cooled, double effect generator cycle, absorption system. In further aspects, this invention relates to a system constructed for use with an absorption refrigeration solution pair consisting of a nonvolatile absorbent and a highly volatile refrigerant which is highly soluble in the absorbent. A disclosed refrigerant pair are ammonia as the refrigerant and sodium thiocyanate as the absorbent. An absorption cycle is disclosed using the thermo physical properties of sodium thiocyanate/ammonia, absorption/refrigerant pair.

  • Patent number: 4067681
    Abstract: A gas cooking range of the smooth top type has four burners positioned under a single plate of heat-resistant glass/ceramic material; and a single igniter and safety control assembly is centrally positioned between the burners. The supply of gas to each of the burners flows through an ignition chamber where it is ignited, and it then flows through a combustion tube to a combustion chamber, where combustion is completed. Some air is mixed with the gas at the fuel supply control valve, and additional air is supplied through the ignition chamber. The burning gas mixture then flows through the combustion tube to the combustion chamber at the entrance of which an additional quantity of air is added to provide the remainder of air necessary for complete combustion.
