Abstract: An existing box-making machine is retrofitted by first removing the pull rolls and impression cylinder and other associated parts and cross-ties. However, the heavy duty side frames and drums, including the print cylinder are left intact in the box-making machine. A vacuum transfer machine is then inserted in the box-making machine and mounted to the existing frame to replace the pull rolls that were removed. The vacuum transfer machine includes a hood enclosure having an impression cylinder for printing, and transport rolls on opposite sides of the impression cylinder for conveying the corrugated boards through the impression and print cylinders and to the die cutter. The boards are held against the transport rolls and the impression cylinder by vacuum generated in a vacuum chamber in the hood which also contains the transport rolls and the impression cylinder. The vacuum chamber contains a plurality of vacuum dampers for controlling the vacuum area in accordance with the size of the boards being processed.

Abstract: The present invention involves a power circuit breaker that conditionally and temporarily enables instantaneous trip protection. A position sensor senses whether the breaker contacts are open or closed. When the breaker contacts are open, the circuit breaker enables the instantaneous trip protection. After the circuit breaker contacts are closed, the circuit breaker continues to enable the instantaneous trip protector for a predetermined period of time. After this time delay, the circuit breaker disables the instantaneous trip protection and the circuit breaker reverts to providing its ordinary protection, such as long-time or short-time protection.
