  • Patent number: 7165046
    Abstract: The present invention implements an auction in which multiple types of goods may be auctioned in a dynamic process. In a preferred embodiment, the present invention is a system and method for a computer implemented dynamic multi-unit auction in which the price paid or received by bidders tends to be independent of their own bids, in which participants may be provided with information concerning their competitors' bids as the auction progresses, and in which the confidentiality of high values may be maintained. Participants' quantities bid at a given time may be restricted to be less than or equal to the quantities bid at an earlier time. These features provide the advantage of improving economic efficiency of the auction design over the prior art.

  • Patent number: 7145117
    Abstract: An apparatus for heating a board product containing glued wood is disclosed. The apparatus includes a heating chamber through which the board product passes. The board product passes through a heating field in the heating chamber provided by means of microwave energy applied perpendicular to the board plane. The clearances between respective side edges of the board and side walls of the heating apparatus are filled by slide pieces made of a material that has a small loss tangent and a low dielectric factor. The slide pieces correct the form of the heating field affecting the board plane.

  • Patent number: 6772669
    Abstract: A method and arrangement for flick ramming projectile components such as shells or propellant powder charges in artillery pieces is disclosed which accelerates the projectile component to the necessary ramming velocity using an electromechanically generated energy supply in the form of starting acceleration from an electric motor. The rotating starting acceleration of the electric motor is mechanically converted into rectilinear acceleration, and the electric motor may be supplemented wit an energy supply obtained from a previously charged energy accumulator which is triggered simultaneously with the start of the electric motor.

  • Patent number: 6740687
    Abstract: Polyurethane foams formed under vacuum (below atmospheric pressure) conditions using toluene diisocyanate or a specific mixture of polyisocyanates with a specific mixture of polyether and graft polyols produces a foam with lower density and better flame retardancy than latex foam, but with equally high resiliency. The foam-forming ingredients are mixed together and foamed under controlled pressures in the range 0.6 to 0.95 bar (absolute), preferably 0.8 to 0.95 bar (absolute). The resulting foam has a ball rebound above about 65 percent.

  • Patent number: 6392338
    Abstract: An organic light emitter includes an anode and a cathode. A first layer of organic material includes a light emitting layer. The first layer extends between the anode and the cathode. A second layer has a refractive index higher than a refractive index of the light emitting layer. The second layer is optically coupled to the light emitting layer, causing an optical waveguide which propagates light generated by the light emitting layer along a direction parallel to a surface of a substrate. At least part of the optical waveguide has an effective refractive index which spatially and periodically varies in a direction parallel to the surface of the substrate.
