Abstract: A device for manipulating data traffic related to a target connected to a data communications network whose elements communicate by means of an HTTP protocol comprises: a redirection device, which is adapted to be connected to the data communications network by means of a plurality of sniffing interfaces and a packet sending interface; a proxy, which is adapted to be connected to the data communications network by means of an HTTP connection interface, a packet receiving interface and a packet injection interface; and is characterized in that the redirection device is configured to monitor, by means of the sniffing interfaces, the network traffic in order to identify within the network traffic at least one data packet associated with the target and to redirect, by means of the packet sending interface, the at least one data packet associated with the target toward the proxy.

Abstract: A printing bridge for silk-screen printing machines has at least one mobile transversal support beam and a doctor retaining and adjusting element slidably attached to the beam. In order to deliver fluid to the doctor retaining and adjusting element, the doctor retaining and attaching element includes a fluid driven actuator connected by tubes to a duct in a section bar on the transversal support beam.

Abstract: A machine for screen-printing on a flat sheet comprises at least one first mobile frame connected to a support plane for the sheet to be printed and at least one second mobile frame that supports a screen for printing, a doctor, and the members to guide and move the doctor. Pairs of eccentric wheels are provided so as to cyclically move the first and second frames in a direction perpendicular to the support plane between an open position, corresponding to which an already printed sheet is removable and a sheet to be printed is introducible, and a closed position in which the sheet to be printed may be retained on the support plane during the printing phase.
