  • Patent number: 7964105
    Abstract: A method for increasing the removal of a higher fraction of liquid from the press cake in any belt press is described. Specifically, the invention incorporates a series of rollers that create multiple pinch points to compress the solid fraction while removing liquid. After each pinch point, the solid material is allowed to separate from the belt, fall by gravity, and repack so that more liquid can be released at each successive pinch point than is possible if the material is fed to multiple rollers and pinch points in series without decompressing as is done is prior art.

    Abstract: A laundry drier control method reads a temperature variation rate per unit time, to enable drying according to the amount and type of an object being dried. The method includes steps of initiating a drying procedure; measuring a temperature variation rate per unit time over the drying procedure; calculating an overall drying time based on the measured temperature variation rate per unit time; and performing the drying procedure for the calculated overall drying time. The drying time determining step is repeated if a substantial increase in the temperature variation rate is detected.

  • Patent number: 7897213
    Abstract: An apparatus, system and method for preparing a surface of a substrate using a proximity head includes applying a non-Newtonian fluid between the surface of the substrate and a head surface of the proximity head. The non-Newtonian fluid defines a containment wall along one or more sides between the head surface and the surface of the substrate. The one or more sides provided with the non-Newtonian fluid define a treatment region on the substrate between the head surface and the surface of the substrate. A Newtonian fluid is applied to the surface of the substrate through the proximity head, such that the applied Newtonian fluid is substantially contained in the treatment region defined by the containment wall. The contained Newtonian fluid aids in the removal of one or more contaminants from the surface of the substrate. In one example, the non-Newtonian fluid can also be used to create ambient controlled isolated regions, which can assist in controlled processing of surfaces within the regions.

    Abstract: A method of estimating the displaced size of a knot in a lumber piece includes the steps of: translating the lumber piece downstream along a flow path between a radiation source and sensor while simultaneously irradiating the lumber piece with radiation from the first radiation source whereby the radiation is attenuated by the lumber piece; collecting a set of radiation intensity data from the radiation sensor as the lumber piece is irradiated; processing the set of radiation intensity data to sum the radiation intensity data and to provide radiation intensity profiles transversely of the flow path direction and corresponding density profiles transversely of the flow path direction; mapping the density profiles to model a set of three dimensional density profiles of the lumber piece; processing the radiation intensity data to determine a clear wood density threshold value for the lumber piece and a maximum density value of the density profiles; and, computing a ratio of the summed density profile values to th

  • Patent number: 7137211
    Abstract: A clothes drying cabinet is provided with a shaker assembly including a bar suspended in the cabinet for supporting clothes hangers. A motor is mounted adjacent the bar and has a drive shaft. A drive weight is eccentrically mounted to the drive shaft of the motor so that upon actuation of the motor, the drive weight imparts a shaking motion to the bar so as to facilitate removal of wrinkles from the clothing on the hangers. A ballast weight may also be provided in the shaker assembly so as to evenly distribute the energy from the eccentric weight regardless of the weight of the clothes hanging on the bar.

  • Patent number: 7134221
    Abstract: A method of detecting lint in a clothes dryer is disclosed. Light is directed through a surface within the clothes dryer, the light being emitted by a light source. The light is received at a photocell if the light is reflected off the surface when lint covers the surface. An indication is provided that lint is present within the clothes dryer if light is received at the photocell. Furthermore, a voltage level detector is positioned within the lint detector and determined if a threshold amount of light is received. In another aspect, if the threshold amount of light is received a warning light, an audio speaker, or an electrical output can be activated. Likewise, the clothes dryer can be automatically shut down. In another aspect, the photocell is a phototransistor. In another aspect, the photocell is a photoresistor.

  • Patent number: 7127830
    Abstract: A method and apparatus for cleaning, rinsing and drying a reticle used in semiconductor device manufacturing, tilts the reticle during the drying process to prevent water from the rinsing process from collecting and remaining on the reticle. The rectangularly shaped reticle is held in a carrier and the top and bottom edges of the reticle may form an angle of at least about 8° with the horizontal to maximize drying efficiency, when the carrier is placed on a horizontal surface or suspended from above.

  • Patent number: 7051453
    Abstract: A system for cleaning a particulate trap comprises locating the trap in a chamber and forcing cleaning air through the trap. The air and removed particulates is extracted from the trap towards a filter. The expelled air essentially without the removed particulates from the chamber, the removed particulates being essentially trapped in the filter. The trap is locatable about a longitudinal axis such that air is urged in a longitudinal direction through the trap. The trap is supportable on at least one rotatable roller to affect rotation about the axis. A motor and blower draws air from the chamber and an air pressure differential about the filter causes the particulate to be directed through the filter and excess air is pumped out of the blower by the motor operating the blower.

  • Patent number: 7044998
    Abstract: When separating steam and gas from a stream containing, possibly glue-coated, fibre pulp produced by a refiner, the hot fibre pulp is directly fed from the refiner to a separation cyclone (4) placed in a drying channel (2) for drying the fibre pulp. A hot drying air flow having substantially higher temperature, about 160° C., than the fibre pulp is blown through the drying channel so that the separation cyclone is surrounded by the hot drying air flow. The light steam containing fraction separated by the separation cyclone is conducted out of the separation cyclone via an outlet conduit (9) away from the hot drying air flow, whereas the separated heavy fibre containing fraction is conducted out of the separation cyclone directly into the hot drying air flow that entrains the heady fraction to a drying plant. Energy is recovered from the light steam containing fraction and ecologically harmful substances are separated from the latter.
