Roderick E. Athey 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: 5343705
    Abstract: A method and apparatus for providing a required deaerating temperature differential between incoming water and sparge steam in a steam generation system having a vacuum deaerator. The present invention selectively combines raising the energy of the sparge steam with flash cooling of the incoming water to provide the required deaerating temperature differential. The energizing of the sparge steam is accomplished by a thermocompression device. The thermocompression device may also be used to reduce the pressure in a portion of the vacuum deaerator to cause the flash cooling of the incoming water.

  • Patent number: 5275091
    Abstract: An apparatus for continuously aseptically processing a food product comprising delicate food chunks of fruit, vegetables or the like immersed in a liquid. The apparatus comprises a heating enclosure into which the food product and a nonsterile gas are introduced into the food product heated to a sterilization temperature, and a holding enclosure which may be integral with or separate from the heating enclosure for holding the food product and a sterile gas introduced therein at the steriIization temperature for a predetermined time. The apparatus further preferably comprises a cooling enclosure for cooling the food product. In a preferred embodiment, a first separator is interposed between the heating and holding enclosures for separating a nonsterile gas from the food product. The food product and an added sterile gas are fed into a rotatable helical feed pump in the holding enclosure.

  • Patent number: 4830865
    Abstract: A method and apparatus are disclosed for continuously and gently aseptically processing a food product comprising delicate food chunks of fruit, vegetables or the like immersed in a liquid. The apparatus comprises a heating enclosure into which the food product and a nonsterile gas are introduced and the food product heated to a sterilization temperature, and a holding enclosure which may be integral with or separate from the heating enclosure for holding the food product and a sterile gas introduced therein at the sterilization temperature for a predetermined time. The apparatus further preferably comprises a cooling enclosure for cooling the food product.

  • Patent number: 4445537
    Abstract: An improved boiler feed water deaerator is provided which includes a plurality of spray valve assemblies therein which are shielded to effectively eliminate undesirable valve chattering and vibrations resulting from the horizontal component of incoming feed water and turbulent water flow through the valves. The valves hereof include an elongated, tubular, open ended water flow-directing shield with a shiftable valve plug adjacent the outlet end thereof. The plug is secured to an elongated stem disposed axially within the shield, and support structure is provided for the stem adjacent the upper inlet of the shield for permitting reciprocation and limited pivoting movement of the stem and plug.
