  • Device and method for noise reduction of a linear damper
    Patent number: 11821488
    Abstract: During the transition from the opening to the closing movement of a glove compartment door, or vice versa, undesirable noises (“clicking”/“popping”) can be reduced by providing regions of a housing surrounding a rotation damper with a contact region made of a material having a lower modulus of elasticity than the material of the remainder of the housing.
    Type: Grant

  • Processes for preparing valve metal powders, powders prepared thereby and uses therefor
    Patent number: 9030799
    Abstract: Processes comprising: melting a mixture comprising a valve metal precursor and a diluting agent in at least one first vessel under a first set of temperature and residence time conditions; transferring the mixture to at least one second vessel; and initiating, in the at least one second vessel, a reaction of the valve metal precursor to form a valve metal under a second set of temperature and residence time conditions; valve metal powder prepared thereby and uses therefor.
