  • Method and apparatus for removing material from the ends of a rotary air lock
    Patent number: 4268205
    Abstract: A rotary vane type air lock for feeding granular abrasive materials into a pressurized chamber having means to prevent the abrasive material from coming between ends of the vanes and the air lock housing. A baffle prevents impingement of the material on the vane ends just before they reach an edge of the inlet opening. A thin sheet of high velocity air directed across the vane ends blasts off any material clinging to the end before the vane end comes into pressure sealing relationship with the housing.
