Abstract: A dust collector is provided. The dust collector includes a housing, a door, and a locking assembly. The locking assembly includes a lockrod rotatably coupled to the door. The lockrod has a first end extending beyond a first side of the door and second end extending beyond a second side of the door. The locking assembly also includes a cam fixed to each end of the lockrod. The locking assembly further includes a keeper assembly to interface with each cam. The keeper assembly includes a keeper having a key and a keeper pin. A longitudinal axis of the keeper pin is offset relative to a longitudinal axis of the key. The keeper assembly further includes a keyway to accommodate the key. The keyway is fixed to the housing proximate one of the cams.

Abstract: An accumulation conveyor system for supporting and moving a plurality of objects. The conveyor system is divided into a plurality of zones wherein each zone includes a top and bottom conveying surface and wherein a space is defined between the top and bottom surfaces. Each zone also includes its own motor positioned external to the space between the conveying surfaces and coupled to the conveying surfaces via a non-slip connection. A control system is connected to the motor and controls the power to the motor so that the conveying surfaces in each zone can be moved independently. Whenever a sensor detects an empty downstream zone, it signals the control system of the upstream zone to power the motor and move the object to fill the empty zone. The control system may also be configured to allow a soft start wherein motor speed is increased gradually.
