Abstract: A package forming unit comprises plural jaw units, each having at least one respective operative assembly for engaging the tube and for at least partially forming the advancing tube, one respective sealing element for at least partially transversally sealing the tube along a transversal sealing band and a pair of interaction tabs for interacting with the tube. Each jaw unit is controllable as a function of the tube filling level in an operative configuration in which the respective operative assembly, the respective sealing element and the respective pair of interaction tabs are controlled in respective active states while advancing along respective operative portions and a partial operative configuration in which the respective sealing element is controlled in the respective active state and the respective operative assembly and/or the respective pair of interaction tabs is/are controlled in a respective inactive state while, in use, advancing along the respective operative portion.

Abstract: A system (10) for the remote detection of substances, comprising a vehicle (20) that is mobile in space and remote-piloted using a control device (40) with a haptic interface suitable to return a force feedback to a user of the control device (40), wherein the vehicle (20) is equipped with a position sensor (22) and a sensor (21) for detecting a physical quantity whose intensity depends on the distance of at least one substance present in a detection point located in a vicinity of the position of the vehicle (20).

Abstract: A forming member for controlling the volume of packages of pourable food products formed from a tube of packaging material and sealed at a number of sections of the tube crosswise to an axis of the tube; the forming member having: a main wall which cooperates cyclically with a first portion of the tube extending between two consecutive sections; and at least one flap extending alongside the wall. The flap is movable, with respect to the wall, between a first position, in which it cooperates with a second portion of the tube, extending between the two consecutive sections, to control the volume, between the two consecutive sections, of the package being formed, and a second position, in which it is detached from the second portion.

Abstract: There is provided a method and apparatus for measuring the optical properties of bulk samples. A probe laser beam is fed into the two arms of the apparatus, a reference arm and a measurement arm, both of which contain optical fiber to conduct the laser lights. The measurement arm includes a free space area for mounting a sample to be tested. The probe beam is directed into the sample in free space. The sample also receives light in free space, rather than via the optical fiber, from a second, pump laser. The interaction of the sample and the pump laser affect the optical properties of the sample. This change in optical properties can be detected by comparing the output signals from the measurement and reference arms.
