  • Device for burning off propellants or explosive substances
    Patent number: 9803588
    Abstract: The invention relates to a device for burning off propellants or explosive substances, which has an activation temperature that lies below the spontaneous ignition temperature of the propellant or explosive substance. The device (1) comprises at least two substances (5, 6) reacting exothermically with one another, wherein at least one first substance (5) is present in a liquid aggregate state below the activation temperature of the device and is separated from at least one second substance (6) by at least one pressure-tight barrier (7).
    Type: Grant
    Filed: July 7, 2011
    Date of Patent: October 31, 2017

  • Bearing-race ring with lubricant and cooling channels
    Patent number: 4194797
    Abstract: A bearing race ring, especially for high-speed applications, e.g. in jet engines, turbines and high-speed power plants, comprises an annular metallic body formed along one of its inner or outer surfaces with axially extending grooves which are inclined to the axis of the ring. Preferably each groove begins at a level at which an adjacent groove terminates and the angle which the groove makes with the longitudinal axis is defined by the formulatan .alpha.=d.multidot..pi./n.multidot.bwherein .alpha. is the aforementioned angle, d is the diameter of the surface provided with the groove, n is the number of grooves and b is the width of the ring.
