  • Method and apparatus for cooling strip and wire material
    Patent number: 7550050
    Abstract: A method of cooling strip or wire products in which, subsequent to being annealed, the product is cooled to a temperature of about 20-50° C. below its oxidation temperature. The product is wound around a drum immediately downstream of an annealing path so that the product lies in mutually juxtaposed turns on the drum. It is thereafter unwound from the drum after a number of turns. The number of turns is such that the product is cooled to a desired temperature. The drum has a diameter that exceeds the diameter at which the product will be influenced mechanically by plastic deformation.

  • Conical disk pair for a belt-driven conical-pulley transmission
    Patent number: 7517295
    Abstract: A conical disk pair for a belt-driven conical-pulley transmission includes a fixed disk, and a movable disk that is axially movable and rotationally fixed to an input shaft. A torque sensor is associated with the movable disk on a side opposite from the axially fixed disk and includes a sensing piston having axially-directed arms that are circumferentially spaced on a side of the sensing piston that faces away from the movable disk. The arms have outer axially—extending teeth that mesh with inner axial teeth of an input wheel. An inner support ring contacts the arms on an inner side radially opposite the outer teeth of the arms and forces the outer teeth of the arms into meshing engagement with circumferentially-positioned axial teeth of the input wheel.

  • Methods for regulating the gear ratio of an automatic power-branched transmission, and automatic power-branched transmission
    Patent number: 7493203
    Abstract: A method for regulating or controlling the transmission ratio of an automatic power-branched transmission. Power is transmitted through a shaft driven by an engine, a variable speed drive, a gear transmission, a driven shaft, and at least two control clutches. The variable speed drive and the gear transmission are connected to each other in such a way that the regulating range of the variable speed drive is traversed in one direction within a first range of transmission ratios, and is traversed in the opposite direction within a second range of transmission ratios during traversing of the entire range of transmission ratios. The shifting strategies result in reduced wear of the endless belt device and allow for comfortable changing between the transmission ratio ranges.

  • Firearm apparatus and method
    Patent number: 7398614
    Abstract: A firearm apparatus and a method of firing ammunition therefrom, where the method utilizes a barrel (12) having a breech end surface (40) and immovably affixed to frame (10), a stand pressure surface (32), and a cartridge container (16) with a cartridge case (26) therein and countermass main body (18) movable in opposite directions. Gas from a deflagrating propellant moves the movable members and applies directionally opposite forces upon the breech end surface (40) and the stand pressure surface (32), which results in the force cancellation and ensures that the barrel (12) remains stable during firing. This solves the problem of the angle of departure and contributes to a high accuracy of shooting.
