  • Patent number: 7122150
    Abstract: A system for determining the efficacy of a sterilization process and communicating that determination to a remote device. The system includes a sterilization sensor and a reader adapted to receive that sterilization sensor. The sterilization sensor has an indicator that undergoes a predetermined optical change when exposed to a sterilization process. The reader has an illumination source for illuminating the sterilization sensor, a color sensor for evaluating the condition of the illuminated sterilization sensor, and an interpretation circuit for interpreting the output of the color sensor to determine whether the optical change has taken place. The reader also has a communication circuit for communicating data from the interpretation circuit to the remote device. In the preferred embodiments, the sterilization sensor is disposable and the reader is reusable.

  • Patent number: 7077995
    Abstract: The present invention provides a new method for the in situ generation of chlorine dioxide from a solution of sodium chlorite and carbon dioxide. The present invention produces effective levels of chlorine dioxide without having to resort to the use of hydrochloric acid, sulfuric acid, hydrogen peroxide, chlorine, sulfur dioxide, or methanol. By eliminating the use of toxic and/or hazardous compounds, the present invention provides a safer means for generating and using chlorine dioxide in a wider variety of applications than previously possible. For instance, the present invention can easily be adapted for the treatment of combustion exhaust gases, flue gases, cooling towers, chilled water systems, contaminated groundwater, and agricultural produce or products.

  • Patent number: 7052649
    Abstract: A dispenser (10) for a volatilizable material has a first member (14) that is substantially cup-shaped with a given diameter (X) and with a given depth (Z) and having a first peripheral flange (16) having a first diameter (D). A second member (18) has a second peripheral flange (20) with a second diameter (D2) greater than the given diameter (X). The first peripheral flange (16) and the second peripheral flange (20) are in intimate contact thereby defining a volatilizable material chamber (22) between the bottom (24) of the second member (18) and the bottom (26) of the first cup-shaped member (14). A volatilizable material (12) such as liquid mercury is placed in the chamber; and a hermetic seal (28) is formed between the first and second flanges. When installed in a fluorescent lamp the volatilizable material is released by heating the dispenser with RF current. The material is released when the vapor pressure within the dispenser reaches about 20 atmospheres.

  • Patent number: 7014819
    Abstract: A device which uses a heat source for heating and diffusing fragrant oils or insecticidal oils. The oil is contained in a reservoir remote from the heat source and the device comprises means for transferring the oil from a reservoir to a surface of a heat-absorbing means wherein heat from the heat source is transferred by conduction to said surface to volatilize the oil.

  • Patent number: 6991761
    Abstract: An automated system for management of information and distribution of materials associated with sterilization procedures includes a network server and client computers that communicate via a computer network. The client computers are distributed among sterilization facilities that require sterilization services. The network server exchanges a variety of information with the sterilization facilities. In response to information from client computers, the network server may trigger distribution of materials to sterilization facilities, and generates reports for record-keeping or cost-accounting purposes. The information distributed by the network server may pertain to the operation, maintenance and control of sterilization equipment, characteristics and capabilities of sterilization materials, and expert technical advice.

  • Patent number: 6984360
    Abstract: The invention concerns a method and a device for sterilising hollow bodies, such as containers, container preforms, tubes and various conduits. The invention is characterised in that it consists in guiding (15) a vaporisable sterilising agent over the walls of the hollow body (9), using guide means (7; 13) enabling the agent to be entirely deposited over the surfaces to be sterilised.

  • Patent number: 6982061
    Abstract: A closed system odorant chamber or wick-style odorizer and method for transferring odorant to an odorant chamber is described. Two cylinders are connected to the odorant chamber, which in turn may be connected to a gas line. The pressure differential between the two cylinders causes odorant to flow into the odorant chamber until an appropriate odorant level is reached. After filling up the odorant chamber, the two cylinders are disconnected from the odorant chamber. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure; and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims under 37 C.F.R. § 1.72.

  • Patent number: 6969497
    Abstract: The system includes an enclosure for providing a closed volume for bactericide vapor. The enclosure has a container access opening formed therein for providing vapor communication between a container and the closed volume. A container interface assembly at the container access opening positions, locks and seals the container to the enclosure. A container door removal system is partially contained within the enclosure and is operably engaged with the enclosure and attachable to a container door of the container for separating the container door from the container. The container door removal system includes an actuator element located external to the enclosure. A vapor injection system is included having an inlet and an outlet for the bactericide vapor.

  • Patent number: 6960320
    Abstract: An exemplary oil burning lamp comprises a reservoir configured for storing a supply of oil, a base, a burner tube and a wick. The base is being sized and shaped to receive the reservoir. The burner tube is movably mounted to the reservoir between a retracted position and an extended position. The burner tube has a first end, an opposing second end and at least one opening. In the retracted position, the both ends are located within the reservoir. In the extended position, the first end is located within the reservoir, the second end is located outside the reservoir, and the opening is located such that fragranced components of oil stored in the reservoir can be entrained by air and emanated from the base. The wick is mounted to the burner tube, extends into the reservoir, and extends outwardly from the second end of the burner tube.
