Patent number: 8720078Abstract: The automatic hair dryer with fluid dispenser is used for smoothing and drying hair. The fluid dispenser is in the form of a tank, which is built into the handle of the hair dryer. When filled with water, the dispenser is capable of discharging a water spray during the drying process and smoothing the hair as it dries, enabling the user to style the hair into any desired hairstyle. A comb is attached to the upper portion of the hair dryer housing, and a moisture sensor is positioned on the teeth of the comb for determining the wetness of the hair, adjusting the heat and intensity of the air being produced by the fan over the heating elements, which is then blown onto the hair. The wetter the hair, the faster and hotter the air will blow.Type: GrantFiled: August 7, 2013Date of Patent: May 13, 2014Inventor: Fawzi Q.M.A.O.A. Behbehani

Patent number: 8713815Abstract: The present invention relates to the vacuum drying of capillary porous bulk materials. The method involves preheating of the material, its loading into the vacuum drying chamber having heating elements followed by cycle-by-cycling heating of the material and vacuum creation in the rapid vacuum impulse action mode with stage-by-stage single or multiple reduction of pressure in the range from 0.1 MPa to 0.0001 MPa followed by the exposure to vacuum unless the material temperature is stabilized. Said cycles are repeated unless the required material moisture is achieved. Cooling of the material is performed in the same drying chamber by alternating cooling in spouted bed and vacuum impulse action. The device comprises two vacuum chambers cone-shaped at their bases with heaters mounted inside them, material loading/unloading system, one or several receivers with pumps connected in parallel to them and connected via vacuum pipeline system with quick-acting valves to the drying chamber inlet.Type: GrantFiled: August 13, 2010Date of Patent: May 6, 2014Assignee: Twin Trading CompanyInventors: Yakov Kuzmich Abramov, Vladimir Mihailovich Veselov, Viktor Mihailovich Zalevsky, Vitaly Grigorevich Tamurka, Vladimir Dmitrievich Evdokimov, Veniamin Sergeevich Volodin, Svetlana Nikolaevna Khapaeva, Anatoly Fedorovich Khanin

Patent number: 8656605Abstract: Described herein are devices and methods for reducing thermal stresses in a rotating, foraminous thin-shelled roll for drying permeable and semi-permeable webs by blocking axial flow of heated air through an axial channel formed between two corrugated layers in the shell. The axial channels extend between spaced-apart, parallel end members each having an inner face, and a plurality of alternating straight thin divider strips and bent thin strips extending axially between and evenly-spaced around the circumference of the inner faces of the end members to form an annular cylinder with radial channels therethrough. Affixing at least one impermeable insert into a radial channel so that it extends through the radial channel and across at least a portion of the faces of the two tiers of bent strips blocks the axial channel therebetween and prevents the passage of air therethrough to the end member.Type: GrantFiled: July 28, 2010Date of Patent: February 25, 2014Assignee: Metso Paper USA, Inc.Inventor: Richard A.

Patent number: 8615899Abstract: Apparatus and method for the non-contact drying of a web of material. The apparatus includes air flotation nozzles for floating the web, and direct air impingement nozzles for enhanced drying of the web. The nozzle arrangement is particularly well-suited to float and dry light weight webs under moderate to high tension. Increased cushion pressure is created to support the web preferably with the same horsepower as conventional arrangements. The increased cushion pressure pad of the nozzle arrangement allows for good flotation with reduced velocities below about 11,500 FPM. Machine direction wrinkles are removed and the result is positive flotation with no marking on the web or ink build up on the air bars. The nozzle arrangement includes pairs of flotation nozzles directly opposing pairs of direct impingement nozzles. A perforated member can be positioned between flotation nozzles within a pair of flotation nozzles to control return air.Type: GrantFiled: August 3, 2009Date of Patent: December 31, 2013Assignee: MegTec Systems, Inc.Inventor: Michael O.

Patent number: 8601718Abstract: A method which allows items, contained in a processing chamber, to be effectively and efficiently dried from an economical point of view and the energy consumption to be thus maintained as low as possible, despite a very high drying power. The method includes subjecting a medium in a container to at least one of an evaporation step and a sublimation step, whereby the medium is cooled, and absorbing via a reversibly dehydratable material in a sorber vapor produced by the medium in the container, whereby the reversibly dehydratable material is thereby heated. Air supplied from a processing chamber to the cooled medium is cooled and dehumidified. This air is then heated via contact with the reversibly dehydratable material and fed back into the processing chamber.Type: GrantFiled: December 1, 2004Date of Patent: December 10, 2013Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Egbert Classen, Bernd Müller
