  • Patent number: 5308485
    Abstract: Disclosed is a filter assembly for use in a baghouse having a cell plate provided with openings. The filter assembly includes a collar, filter bag, tubular supporting cage and locking ring. The filter bag filters particulate material and extends from below the cell plate. The collar supports the filter bag and has a longitudinally extended portion and a flange portion. The longitudinally extended portion is affixed to the filter bag below the cell plate, while the flange portion extends along the cell plate as a rim above a respective opening. The collar acts as a gasket to seal a respective opening in the cell plate. The tubular supporting cage has a longitudinally extended portion that structurally supports the filter bag. The locking ring is integrally fixed to the supporting cage and locks an arrangement of the filter bag, collar and cage in place. The locking ring also can include a venturi affixed thereto to assist in filtering and cleaning operations.

  • Patent number: 5202021
    Abstract: Disclosed is a filter assembly for use in a baghouse having a cell plate provided with openings. The filter assembly includes a molded collar, filter bag, tubular supporting cage and locking ring. The filter bag filters particulate material and extends from below the cell plate. The collar supports the filter bag and has a longitudinally extended portion and a flange portion. The longitudinally extended portion is affixed to the filter bag below the cell plate, while the flange portion extends along the cell plate as a rim above a respective opening. The collar acts as a gasket to seal a respective opening in the cell plate. The tubular supporting cage structurally supports the filter bag and has a longitudinally extended portion and a collar portion. The longitudinally extended portion supports the filter bag, while the collar portion partially overlaps the flange portion of the collar. The locking ring locks the filter bag, collar and cage in place.

  • Patent number: 4745516
    Abstract: A mobile storage system includes movable carriages that are stoppable by solenoid operated mechanical safety brakes. The solenoids are controlled by an electrical circuit that includes a safety floor and/or a safety sweep. Actuating the respective safety switches activates the circuit to energize the solenoids for operating the brakes. The safety floor portion of the circuit is designed to energize the brake as long as a safety floor switch is actuated. The safety floor circuit portion contains a timing device that holds the solenoid in the energized condition for at least 3 seconds after deactuation of the actuated safety switch, so that a person walking across the floor does not cause the solenoids to chatter. The safety sweep circuit contains first timing means for deenergizing the solenoid approximately 3 seconds after safety sweep switch actuation. If the actuated switch remains open after approximately 5 minutes, or if a safety sweep switch fails, an audio alarm sounds.

  • Patent number: 4579488
    Abstract: A boring bar assembly comprises a shank portion and a detachable head portion supported thereon for rotary movement. The head portion may carry one or more removable cutting tool inserts for machining. The head portion is pinned in a fixed position on the shank portion by a shear pin. Excessive pressure in machining causes the pin to shear and allows the head portion to rotate on the shank portion and move away from the surface being machined, thus reducing tool breakage and damage to the parts being machined. An axially offset fluid passageway extends longitudinally through both the shank and head portions to direct liquid coolant onto the cutting tool surface. The axial offset of the passageway does not weaken the boring bar in flexure as much as an axial passageway.
