Publication number: 20200025636Abstract: An assembly for measuring torque and/or axial load for capping heads comprises a containing body, a torque and/or load sensor housed within the body, and an interface that connects a capping head to the body. The interface is coupled to the torque/load sensor to transfer torque applied on the interface to the torque sensor and/or to transfer load applied on the interface to the load sensor. The interface comprises a first part fixedly constrained to the capping head such that the first part is brought into rotation and/or translation by the capping head, and a second part coupled to the torque sensor for transferring a torque thereto and/or to the load sensor for transferring a load thereto. The torque and/or load are applied by the first part to the second part, and the first part transfers a torque to the second part in the absence of a reciprocal contact.Type: ApplicationFiled: January 31, 2018Publication date: January 23, 2020Inventors: Marco Caffa, Marco Cipriani, Alberto Cirio

Publication number: 20190248636Abstract: A capping head for applying caps on containers or bottles and a capping assembly are provided. The capping head comprises a gripping assembly having a hollow body longitudinally extending along a vertical axis and internally defining a seat for the cap, the seat being delimited at its lower end by an inlet mouth for the introduction of the cap. A moving assembly is connected to the gripping assembly for controlling the movements thereof and is hermetically separated therefrom, and an ejector member is housed inside the hollow body of the gripping assembly, in such a manner that it is free to axially slide. The ejector member carries first and second magnetic elements such that a relative axial approach of the second magnetic element towards the first magnetic element results in a translation of the ejector member towards the lower inlet mouth of the gripping assembly.Type: ApplicationFiled: October 18, 2017Publication date: August 15, 2019Inventors: Marco Caffa, Marco Cipriani

Patent number: 8536751Abstract: An electromagnetic device has a stator and a rotor rotating between facing surfaces of the stator and bearing a plurality of magnets distributed at regular intervals along its periphery. The magnets are so arranged that they form a sequence of alternately opposite poles on the surfaces of the rotor directed towards the stator, and the stator comprises two sets of independently supported magnetic yokes located at both sides of the rotor in front of the magnets. The magnetic yokes have two axially oriented arms, the end surfaces of which, in static conditions of the rotor, at least partly face a pair of successive magnets on a same surface of the rotor.Type: GrantFiled: January 21, 2009Date of Patent: September 17, 2013Assignee: AVIO S.p.A.Inventor: Marco Cipriani

Publication number: 20090235178Abstract: One aspect of the present invention provides a mechanism for recognizing and distinguishing between human would-be users of websites and automated agents attempting to gain unauthorized access to the website. More particularly, when a website server receives a registration request from a would-be user, a distorted image of a common object (e.g. a house, cat, etc.) is generated. The distorted image is shown to the would-be user, and the user must insert the correct name of the object depicted in the image to gain access to the website. By placing a limit on the time interval in which a user can provide a correct identification of the displayed object, this embodiment attempts to harness the conceptual and cognitive reasoning facilities of human users to distinguish them from automated agents. The challenge to the user is enhanced by restricting the correct identification to the language of the browser viewing the website.Type: ApplicationFiled: October 22, 2008Publication date: September 17, 2009Applicant: International Business machines CorporationInventors: Marco Cipriani, Filomena Ferrara, Scot Maclellan, Favio Pinzauti
