Abstract: A conventional chain capable of reserving lubricating oil is complex in shape and expensive since each chain plate is formed with countersunk recesses and through-openings. Since the recesses are formed in an overlap region, the chain tends to rattle, producing noise. In the present invention according to which lubricating oil is fed toward a connecting pin, the lubricating oil is transferred to the connecting pin to effect intended lubrication. Part of the lubricating oil thus fed adheres to the recessed surfaces of the recesses and is prevented from immediately flowing down by viscous friction resistance and surface tension in the recessed surfaces. Thus, the oil is held in its adhering state. The lubricating oil gradually flows down to be used for lubrication as the chain moves. Thereby, after the chain has passed by an oil feeder, the connecting pin of the chain stays in such a state that oil is fed continuously for a long time.

The inner link plates form with their bearing bushings two chain link sections (1, 2) that are easily interconnected at the junction (J) and also easily disconnected again at the junction. Both sections are made by casting or drop forging.

Abstract: A sealed chain is provided that traps lubricant and dust electrostatically. The chain includes an inner plate which is penetrated by a bushing and an outer plate which is penetrated by a pin. The inner and outer plates are connected alternatingly. Between the inner plate and the outer plate, a seal which is coaxial with the bushing and the pin, is provided in contact with the inner and outer plates. The contact area between the seal and the inner plate is smaller than the contact area between the seal and the outer plate. An annular dust hole, which is around the end of the bushing for sliding on the pin is formed on the inner part of the surface of the seal facing the inner plate. When chain bends due to, for example, winding by a sprocket, the seal slides on the inner plate thus, generating electrostatic charge. The end of the bushing 12, which slides on the pin, is encircled by the dust hole, which entraps lubricant electrostatically on sliding surfaces and dust formed by the wear of sliding surfaces.

Abstract: For the movement of work-in-process materials on a storage or manufacturing floor, a grid of computer-controlled, unmanned jib cranes is established. The cranes' operational areas overlap. A crane can place an individual part or a magazine of parts on an elevated, revolving pedestal which then automatically rotates 180 degrees so that the next crane in line can pick up these materials and move them into its own area. The hand of the crane is moved so that it can place its load directly into the position in the machine tool where it undergoes its next process. The arm of the jib crane is fully retractable and computer-controlled, using a laser integrated into the computer's system to aid in detecting the crane's hand location at each delivery position that the crane visits. The jib cranes can lift parts up to a level that places them near the ceiling of the manufacturing floor area.

Abstract: A rotor link attached to a debarking cylinder. An open link is attached to the rotor link and a chain is attached to the open link. The open link must be rotated forward in the direction of rotation of the debarking cylinder so that a flat area of the rotor link is presented adjacent the open area of the open link. This makes it less likely that the link will be disengaged by random movement of the chain during a debarking operation. Thus, individual chains can be removed without removal of the attachment rod and all the chains on the cylinder. A second chain may be attached to the open link through a similar series of translational and rotational movements.
