20090084873 | Gaseous Fuel Injector for Internal Combustion Engines - An injector of gaseous fuels for internal combustion engines includes a valve body into which the fuel is admitted by an inlet aperture and from which it is discharged by an outlet aperture, and a seating associated with a respective shutter. The shutter includes a diaphragm and a moving armature of an electromagnet held in a centred position by the diaphragm. The electromagnet is capable of causing, in a controlled manner, movement of the shutter relative to the seating from and to a position of shutting off the seating to allow or shut off the flow of fuel through the seating. The seating has a cross-section for passage of the fuel having the form of at least one slot extending along a first direction of development predominant with respect to a second direction of transverse development of the cross-section and the cross-section has a perimeter sealing edge with a cross-section of substantially rounded shape capable of providing sealing contact against a surface of the shutter facing it. | 04-02-2009 |

20130182221 | APPARATUS FOR INSPECTING THE FUNDUS OF THE EYE - The present invention relates to an apparatus for inspecting the fundus of the eye, comprising:—lighting means configured to project a light beam for illuminating the retina of one eye; and—an optical path comprising one or more lenses configured to optically conjugate the retina with a receiving surface of acquisition means configured to acquire one or more images of the retina; and—a beam splitter device configured to divert a part of the light, which is reflected by the retina and directed towards said acquisition means, towards first photosensitive elements; and—a control unit operatively associated with said first photosensitive elements, said acquisition means and said lighting means, said control unit deactivating said lighting means when the light energy received from said first photosensitive elements overcomes a predefined threshold value; and—first LED devices configured to project light targets onto the retina, which the patient must stare to keep the eye still during the examination. The mentioned first photosensitive elements and first LED devices are arranged together in a single integrated optical unit configured to receive light from the retina and to project light onto the retina through said beam splitter device. | 07-18-2013 |
