Abstract: A system and method provides for the identification and monitoring of carriers within a pneumatic carrier system. Each carrier which is to be employed within the system includes an identification device such as a radio frequency identification (RFID) chip which has stored thereon identification information for the carrier. Positioned throughout the system are communications devices such as antennas and readers which are employed to read and/or write identification information on the chip. When a carrier is put in the system, a destination location can be associated with the particular carrier ID. This associated information is then employed to, among many things, monitor and confirm identity of the carrier as it moves to its destination.

Abstract: To supply a powder lacquer sprayer, the coating powder is pressed by a pig through the supply line and, in the process, it is fluidized from the side of the pig which is turned toward the powder. The fluidization air can be led to the powder, for example, by a central passage opening of the pig or through an air permeable wall of the connection line. For the dosage of the coating powder, one uses the push medium which drives the pig.

Abstract: To equally space items along a first path, a predetermined number of items is moved towards each other to minimize distances between the items, and a gear mechanism is engaged with each item. The gear mechanism includes crossed bars, wherein pairs of the bars are coupled at middle joints so that each pair of bars forms an X-shaped structure and opposite ends of an X-shaped structure are coupled at end joints to respective ends of neighboring X-shaped structures. The gear mechanism is activated so that the gear mechanism acts upon each item and moves each item along the first path a predetermined distance to equally space the items.

Abstract: A conveyor and associated method for diverting closely spaced articles conveyed along the conveyor. The conveyor includes a conveyor belt with belt rollers oriented to rotate on axes oblique to the direction of belt travel. A series of arrays of bearing surface elements are arranged end to end along the length of the conveyor. The bearing surfaces may be static or rotational. Each array defines a roller-control zone in which the array is selectively activated with its bearing surface elements in contract with the belt rollers or deactivated with its bearing surface elements out of contact with the belt rollers. As the belt advances through an activated roller-control zone, the belt rollers rotate to propel a conveyed article toward a side of the belt. The contiguous roller-control zones are sequentially activated and deactivated to direct articles to the side and off the belt or to let them pass straight through.
