Patent number: 7413408Abstract: A spoiler attached to helicopter main rotor blades, tail rotor blades, propellers, aircraft wings, and machined into turbine blades, that reduces vibration and silences their operation. Also, when added to a substantial part of the trailing edges of its rotor blades, the spoiler eliminates the repetitive pop-pop sound common to current helicopter flight. Preferably, the spoiler is made from durable resilient materials that bend with resistance for high speed oscillation and it is secured on the top or bottom side, or both, of the trailing edge of a blade or wing. Further, the free edge of the spoiler exhibits a non-repeating pattern of feather-like projections that collectively break up vortex formation so that the next wing or blade traveling through the same location has clean air/fluid in which to move. In addition to noise reduction, the spoiler increases blade efficiency and wing lift.Type: GrantFiled: February 22, 2007Date of Patent: August 19, 2008Inventor: Samuel B Tafoya

Patent number: 7413435Abstract: The present invention relates to melting plate candles which employ heat conductive elements to distribute heat from a burning flame at a wick to a support plate for a solid fuel and to the body of said solid fuel, so as to more rapidly liquefy the solid fuel, such as paraffin wax, and to more uniformly and intensely heat such fuels to increase the efficiency of consumption thereof and to more rapidly release volatile materials contained within said fuels. The heat conductive support plate is configured so as to have a capillary pedestal upon the surface thereof, which cooperatively engages a wick holder comprising a preferably consumable wick and heat conductive fins which conduct heat from a flame upon said wick to said support plate. The wick holder also provides capillary fins by which liquified fuel is transported from said support plate to said flame, Said wick holder further engages said capillary pedestal in such a locking manner as to resist accidental removal from said pedestal.Type: GrantFiled: September 10, 2004Date of Patent: August 19, 2008Assignee: S. C. Johnson & Son, Inc.Inventors: Elizabeth J. Jameson, Chris A. Kubicek, Thomas J. Szymczak, Padma Prabodh Varanasi, Joel E. Adair

Patent number: 7413438Abstract: A computer program, method, and system for dynamically and interactively providing nutrition content information for consumables such that a user may monitor, tailor, plan, and review their intake thereof in light of a health-related interest or concern, such as, for example, weight-loss, food allergies, or diabetes or other nutrition affected illnesses or disabilities. Consumables are categorized and displayed in lists associated with an appropriate color to draw attention to relative nutrition content and to facilitate quicker and easier evaluation of a consumable of interest. Summaries are provided of a user's actual intake in light of a pre-established target intake for a particular day. Detailed reports may be generated showing consumption over a user-specifiable time period.Type: GrantFiled: August 1, 2005Date of Patent: August 19, 2008Inventor: Joseph J. Bisogno

Patent number: 7413439Abstract: A stomach model visual dieting aid includes a generally flexible three-dimensional model of the human stomach having at least length and width dimensions approximately equal to the dimensions of an actual average-sized human stomach and a stomach model storage container including an outer cover and a generally liquid-impervious inner liner mounted on the inner wall of the outer cover. The stomach model storage container is operative to receive and releasably retain the three-dimensional model of the human stomach therein with at least one of said three-dimensional model of the human stomach and the stomach model storage container being at least one of foldable, bendable and rollable to substantially decrease the size of the three-dimensional model of the human stomach when mounted within the stomach model storage container to facilitate transport thereof.Type: GrantFiled: July 29, 2005Date of Patent: August 19, 2008Inventor: Marsha L. Tiessen

Patent number: 7413441Abstract: A three-dimensional sarcomere muscle cell teaching model which contracts and extends. A slide mechanism and support base allows opposing rigid walls which represent sarcomere cell Z-Band structures to slide in relation to one another. A rigid wall representing the sarcomere cell M-Line structure is positioned between the Z-Band structures. A plurality of rods representing Myosin Rods extends outward on each side of the M-Line structure toward the Z-Band opposing structures. Other rods, representing Actin Rods, extend from each of the Z-Band structures toward the M-Line structure. Each Actin Rod corresponds to one or more Myosin Rods, is positioned between the M-Line and Z-Band structures, and slide past one another when the Z-Band structures are moved. Opposing tension is applied to the Myosin Rods to maintain them in position between the Z-Band structures. Filaments extend from the Actin and Myosin Rods to simulate the interaction between the Actin and Myosin Rods.Type: GrantFiled: November 22, 2005Date of Patent: August 19, 2008Inventor: Mark J. Bigelow

Patent number: 7413443Abstract: The invention discloses an electrical connector comprising an insulating housing and a plurality of terminals. The insulating housing comprises a base having at least one group of slots and at least one block portion. Each terminal is inserted into one of the slots. A first position and a second position are respectively defined according to the contact between the terminal and the slot. A base line is defined from one end of the block portion away from the base. A first distance is defined from the base line to the first position. A second distance is defined from the first position to the second position. A third distance is defined from the base line to the position where the terminal protrudes from the block portion. The first distance is larger than or equal to 1.5 times the second distance, and the third distance is smaller than the first distance.Type: GrantFiled: October 11, 2007Date of Patent: August 19, 2008Assignee: Lotes Co., Ltd.Inventor: De Siang Ju
