  • Apparatus and method for applying an absorptive coating to an x-ray tube
    Patent number: 7209546
    Abstract: An apparatus and method for applying an absorptive coating to a portion of the evacuated enclosure in an x-ray generating device is disclosed. The absorptive coating is applied to the inner surface of the evacuated enclosure to enhance its heat dissipation characteristics, which in turn assists in tube cooling during x-ray production. The absorptive coating is applied atop an intermediate bonding layer. Both the absorptive coating and the intermediate bonding layer are applied to the evacuated enclosure surface by electroplating processes. A plating apparatus comprising the evacuated enclosure portion, a plating fixture, and a base plate is used both to contain the electroplating solution during the plating process, as well as to facilitate its entry into and removal from the evacuated enclosure. A method of employing the plating apparatus to apply the intermediate bonding layer and the absorptive coating is also disclosed.

  • Cold water disinfection of foods
    Patent number: 6458398
    Abstract: The invention includes a method of reducing the microbial population on food in a container. The method generally involves the application of both a surfactant and ozone containing wash liquor to the food. The method includes introducing a wash liquor into the container, thus contacting the food with the wash liquor and wetting the food. A surfactant is then added to the wash liquor. This surfactant containing wash liquor is then allowed to contact the food for a period of time. Next, a combination of ozone gas, oxygen and/or air is mixed into the wash liquor to form an ozonated wash liquor. This ozonated wash liquor then remains in contact with the food for a period of time.
