  • Patent number: 6922909
    Abstract: By providing a plurality of portals in a housing which forms a hair dryer attachment which is merely fixed to the exist portal of any conventional hair dryer, a hair dryer attachment is realized which is capable of substantially reducing the drying time required for drying the hair of any individual, while also being easily employed and comfortable. In the preferred embodiment, at least one raised, sloping panel is formed adjacent the inlet portal of the attachment with the panel sloping outwardly from the generally circular shaped inlet portal. In addition, a plurality of apertures or portals are formed in the panel for enabling ambient air to freely flow therethrough. In this way, the heated air flowing through the central portion of the attachment creates a low-pressure zone on the inside surface of the portals, drawing ambient air through the portals into the interior of the hair dryer attachment, thereby enabling the quantity of the air reaching the hair of the user is substantially increased.

  • Patent number: 6918195
    Abstract: It is known from the art to mount a wire gauze (10) onto a drum (1) with a permeable drum jacket (8) under pretension, for example, for allowing air to flow through a web of material placed on said drum, said wire gauze optionally being disposed even at a distance to the drum jacket surface. The air thus flows more evenly across the surface of the web of material and no visible marks on the web of material, caused by the contact of the web with the intermediate space between the holes of the drum, occur. The wire gauze has to be elastically fastened on the front faces of the drum to compensate also for thermal stresses. According to the invention, preferably U-shaped spring elements (11) extending radially to the axis of the drum are fastened on the front face of the drum and on a tensioning ring (13) for the gauze provided on the level of the drum outer diameter.

  • Patent number: 6910284
    Abstract: The objective of the present invention is an accelerated drying process for wood, capable of use with all species and of maintaining the quality of the dried wood intact, in which the temperature of the system is kept within the glass transition temperature range, for an appropriate period so as to attain the intended humidity ratio of the wood. It relates to an accelerated drying process for wood based on the rheological properties (hygro-thermalviscoelastic) of the latter, where the glass transition temperature of lignin is used as a relaxant or neutralization agent for the residual growth stress of trees, as well as those from the drying process. The process is controlled by monitoring the temperatures of the wood through the use of thermocouples placed along the length of the pieces. Furthermore, the use of the process of the present invention provides a significant reduction in the drying time and a reduction of the defects because molecular fluidity is maintained.

  • Patent number: 6892472
    Abstract: A method and apparatus for rinsing and spin-drying a hydrophobic material such as a hydrophobic semiconductor wafer improves wafer drying while at the same time reduces the formation of residual contaminants on the dried surface of the wafer. This is accomplished by first establishing a safe-zone between a minimum rotational speed above which drying proceeds satisfactorily and a maximum rotational speed above which contaminants dry on the wafer's surface. A spin-rate profile can then be adopted such that the rinse/dry process proceeds within the safe zone.
