Abstract: An absorbent element for the absorption of body fluids in sanitary articles comprises a first layer of sheet material presenting an array of hollowed formations (16) with respective mouth parts, as well as masses (18) of superabsorbent material that is able to expand as a result of the absorption of body fluid, which are set in the aforesaid hollowed formations (16). A second layer of sheet material (12) is applied on the first layer of sheet material (10) so as to cover the mouth parts of the hollowed formations (16). At least one of the layers of sheet material (10, 12) is permeable to body fluids to enable the body fluids themselves to penetrate into the hollowed formations and be absorbed by the masses of superabsorbent material (18) that expand in the hollowed formations (16), creating a first level of absorption of body fluids.

Abstract: A machine for making coffee has a cylindrical chamber in which the head walls are made up of two pistons mounted on circulating ball screw actuators. Once the coffee powder is put into the chamber, the pistons are brought together to exert pressure, after which hot water is introduced to make the infusion. A motor for one of the actuators is in a lower casing on which the chamber is directly mounted for compact construction.

Abstract: The invention is a pump for coffee machines which simultaneously carries out the functions of water measurer and heater.The pump consists of a cylinder with a piston inside which sucks the water from a tank and directs it towards the devices it serves, and in which there are electronic devices for the control of the run of the piston and the consequent measurement of the water. The piston is moved by a piston rod which is externally threaded and forms part of a circulating ball actuator.Heating takes place by way of a resistance coiled around the cylinder jacket with the whole in turn enveloped by an insulating covering.

Abstract: A softened unperforated film and a perforated die which is generally cylindrical in movement are brought into contact and exposed, in a predetermined region, to a pressure gradient oriented radially of the die. The pressure gradient causes the local penetration of the film into the holes of the die and the consequent perforation of the film itself. The movement of the die is supported in a rigid manner solely upstream and downstream of the predetermined region in the common direction of movement of the film and the die. The die itself is subjected to a pulling action, along its generatrices at least close to the predetermined region.
