Abstract: A method and system include a SDP controller in a SDP receiving a request from a first device for communicating with a second device. The second device is in the SDP. A firewall includes a connection table configured to map an identity of the first device and second device, and a filter table is configured to open and close ports. The SDP controller authenticates the first device, and provides the identity of the first device to the second device. The second device transmits a first packet to the first device. The firewall maps in the connection table, the identity of the first device in association with the second device. The first device transmits a second packet to the second device. The firewall determines that the identity of the first device is in the connection table for communicating with the second device and forwards the second packet to the second device.

Abstract: A machine (2) for handling partially formed containers (6) comprising an indexing conveying device (8), a feeder (4) arranged to supply to the conveying device (8), per index, a plurality of partially formed containers (6), one or more stations (18, 20) comprising a plurality of devices arranged to perform substantially identical operations on a group of containers constituted by the plurality of partially formed containers (6), the indexing conveying device (8) being arranged to advance the group through the stations (18, 20), and a controlling device arranged to cause the feeder (4) to reduce to an integer the number of partially formed containers (6) supplied, per index, to the conveying device (8). The machine (2) is operated by the controlling device via a number of servomechanisms associated with each of the operations carried out by the machine.
