  • Patent number: 6877250
    Abstract: In an apparatus for a treatment of a wafer at elevated temperatures, the wafer is taken out of the reactor after heat treatment with the help of a mechanical transport apparatus which preferably grips the wafer around the circumference and on the under side. The transport apparatus includes a wafer surrounding ring. The wafer is placed in a floating wafer reactor where it is cooled in a controlled manner. Transport for further action or treatment then takes place.

  • Patent number: 6834597
    Abstract: This relates to a furnace that is useful in safely detonating or demilitarizing munitions or explosives, particularly small caliber munitions. The preferred variation includes a series of chambers having a set of runners or tracks passing amongst the various chambers to allow movement of the munitions from chamber to chamber in trays. The first chamber is heated in such a way so that a tray of munitions placed on the runners in this chamber are baked and detonated. After the detonation is generally complete, the tray containing the then-detonated munition fragments is slid through an opening at the end of that heated detonation chamber into a first cooling chamber. Generally, this movement takes place by addition of another tray containing non-detonated munitions into the first chamber.

  • Patent number: 6775925
    Abstract: Apparatus and a method for the evaporative cooling of a web within a dryer in a compact manner. Excess fluid overspray is controlled, thereby avoiding problems with fluid depositing on internal surfaces of the dryer, which can cause mineral build-up and can result in web breaks or quality defects if fluid drips onto the web. More specifically, a water delivery system is used which directs a water mist to the web by appropriate design and placement of the spray nozzles. The quantity of water delivered to the web is regulated, and is preferably based upon web temperature. Excess mist is controlled by directing hot air to effectively vaporize the excess mist before it is able to contact the internal surfaces of the dryer enclosure and its internal components.

  • Patent number: 6745706
    Abstract: A system for disposing of municipal solid waste 10) provides commercially-available equipment that is modified to initially remove identifiable unwanted components from the waste (12), and then chop the waste into small pieces (16) of a size suitable for handling and combustion. The moisture content of the waste is reduced in a closed system (20) by passing dry air through the waste in a confined space (30) to absorb moisture and produce moist air, which is then dehumidified via refrigeration equipment (34). The dehumidified air is recycled (30, 40) through the waste repeatedly through the closed system (20) until the water content has reached the predetermined amount. The waste is stored in a bunker (41) for later burning, or is immediately burned in a furnace (24) to produce heat that is used to produce steam (50), which drives a generator (26) to produce electricity (52) that is partly used to power the process and partly sold commercially.

  • Patent number: 6739073
    Abstract: A method for performing multiple cleaning and vacuum drying operations in enclosed vessels uses cleaning and vacuum drying apparatus, low-dissolved-air cleaning solution, and drain-to-vacuum process to produce vacuum in a cleaning vessel, so that influence of air pressure on the operations is minimized. The method utilizes physical features that boiling points of general liquids lower with reduced pressure, that liquid saturated vapor pressure reduces with lowered temperature, and that two vacuum vessels of different working temperatures would have a pressure differential between their saturated vapor pressures, and uses heat control units and heat egress units to regulate temperature and pressure in the vacuumized cleaning vessel, so that wet clean, dry clean, vacuum heat drying, and vacuum freeze drying can be performed on the same apparatus, and low-pressure gas used in the dry clean and cleaning solution and waste solution can be recovered to achieve environment protection and energy saving.

  • Patent number: 6725569
    Abstract: The device (10) and method are used for ventilating an offset pocket space (12) located in a drying section of a papermaking machine by injecting air from a heated dry air supply inlet (11). The offset pocket space (12) is situated between a set of three axially-parallel drying cylinders (20) over which consecutively runs a paper web (14). The device (10) comprises a first air outlet (50) where a first air stream is directed into a cleft (34) defined where the felt (16) rejoins the felt roll (26), and a second air outlet (52) where a second air stream is directed in close proximity to the felt (16) at a location which is upstream of the cleft (34). In use, the device (10) and the corresponding method allow the first air stream to flow through the felt (16) and lift the paper web (14) away from the felt (16) so as to reach the offset pocket space (12). The second air stream creates an air curtain to lower the pressure in a zone between the first (50) and the second air outlet (52).
