  • Patent number: 6162392
    Abstract: A process for sterilization of a liquid in a continuous system comprising a series of steps. First the liquid is continuously pumped into a pressurized system. A process for sterilization of a liquid in a continuous system where, in the first step, the liquid is continuously pumped into a pressurized system. Second, the pressure on the liquid is increased in a first pressurization stage. Next, the liquid is increased in pressure in a second pressurization stage. Fourth, the liquid is held at an elevated pressure for a predetermined period of time to kill off microorganisms within the liquid. The liquid is then rapidly depressurized to fracture microorganisms within the liquid. The apparatus for producing this process includes a continuous liquid treatment system with a pump, a first stage intensifier, a surge drum, a second stage intensifier, a pressure receiver and a pressure reducer.

  • Patent number: 6159422
    Abstract: The invention provides methods and apparatus for treating hazardous biological wastes. According to one exemplary method, a biological waste material is placed into a chamber and a vacuum is applied to the chamber. After the pressure within the chamber is sufficiently reduced, water vapor is introduced into the chamber and electromagnetic radiation energy is applied to produce a plasma. In one particularly preferable aspect, the chamber is allowed to reach a static condition before the water vapor is introduced. In this way, the water vapor is able to equally distribute itself throughout the volume of the chamber so that an equally distributed plasma can be produced upon application of the electromagnetic radiation energy.

  • Patent number: 6149699
    Abstract: Rather than providing replaceable filter elements in fixed permanent housings which require replacement by plastic bagging techniques, easily disposable and incineratable filter modules are removed and replaced as integral units while providing complete protection against contaminants from filtered exhaust air from enclosures containing airborne or potentially airborne hazardous materials, such as biological safety cabinets, fume hoods, cages for contaminated animals, nuclear facilities, etc. The disposable filter modules are removable and replaceable by a technique in which the modules are maintained under negative pressure via a filtered vacuum source at all times while the module inlets and outlets are open. Sealing of the openings is by small sheets of polyethylene film, and no bagging such as in the known "bag in, bag out" technique is required.

  • Patent number: 6149864
    Abstract: A method is provided for sterilizing materials, particularly polymers, for drug delivery and implantation, wherein the material is treated with supercritical fluid carbon dioxide at pressures in the range of 2000 to 3000 psi (140 to 210 bar) and temperatures preferably between 30 and 45.degree. C. for periods between 20 minutes and six hours, more preferably between 0.5 and 2 hours. Agitation, pressure cycling, and the presence of water were found to enhance the sterilization method, which promotes diffusion of the supercritical fluid carbon dioxide into the cells of the microorganism to thereby alter the pH within the cells, killing them. The magnitude and frequency of the pressure cycling, as well as the process time and temperature, may vary according to the type and form of the material to be sterilized and the type of organisms to be killed.

  • Patent number: 6136267
    Abstract: A fuel ignition arrester system that has a feedback control to maintain the fuel/air mixture in the ullage of a fuel tank above the flammability range. The system uses a photoelectric detector to signal when the fuel/air mixture concentration falls or rises to a predetermined concentration value. The predetermined value is selected to be higher than the upper limit of the flammability range so that the fuel/air mixture is maintained above the range and, thus, incombustible. A fuel pump and piping system with nozzles is arranged to inject fuel into the ullage when the concentration falls to the predetermined value and to stop injecting fuel when the concentration rises to the predetermined value. A flammability detection system includes the detector and a controller that produces an annunciating signal when the fuel/air mixture concentration is equal to or between the upper and lower limits of the flammability range.

  • Patent number: 6123900
    Abstract: This invention provides for a method of sterilizing a chemical composition contained within a closed container (20). The chemical composition is initially mechanically filtered (12) and then the containers (20) are closed and hermetically sealed within a first sealing layer (24). The first sealing layer (24) and the chemical container (20) form a single layer sealed enclosure (26) which is then encased within a second sealing layer (30) and hermetically sealed to form a second layer sealed container enclosure (32). The second layer sealed container enclosure (32) is then inserted into a carton (36) having a third sealing layer (38) lining. The carton is closed and then irradiated with gamma radiation at a predetermined dosage level to sterilize the contents of the container (20). The closed cartons (36) are then transported to operational sites where the plurality of sealing layers (24, 30 and 38) provide for optimized contamination reduction.

  • Patent number: 6120737
    Abstract: An arrangement is used with a light bulb for emitting fragrance. The arrangement has a ring or other shaped member made of a first polymer. The first polymer has a first low melting point which is about a first temperature at a spaced location from the surface of the light bulb when it is lit. A volatilizable fragrance is combined with the first polymer for being volatilized from the first polymer when the ring member is exposed to the first temperature. A plurality of feet extend inwardly of the ring member for engaging the surface of a light bulb to maintain the ring member at the spaced location on the light bulb. These spacer feet are made of a second polymer having a second high melting point compared to the first low melting point. The second melting point is above a second temperature at the surface of the light bulb when it is lit.
