Abstract: A paint spraying machine includes an apparatus for containing and removing the leakage of paint drops from a rotating joint, without the risk of damaging the article being sprayed, and thus without the need for downtime to replace sealing elements. The rotating joint includes a hollow shaft for distributing paint, a drum including a plurality of flanges that define separate chambers for different paints, a plurality of seals for separating the different paints in the different chambers which together form a high-pressure circuit, a low-pressure circuit to refrigerate the seals, improve their sealing and possibly intercept leaking paint, and a plurality of centering rings provide for correct assembly of the seals and the correct alignment of different flanges. The rings are hollow, and allow for the passage of the refrigerating/cleaning liquid under low pressure.

Abstract: Method and apparatus for acquiring volumetric CBCT radiographies in an apparatus having a rotary supporting arm, at the ends of which at least an X-ray source and at least an X-ray sensor are positioned, the supporting arm rotating the at least one source and the at least one sensor around a patient. The method includes the steps of positioning a patient on the positioning device, and acquiring a CBCT image through a trajectory having an angular extension lower than 360°, wherein the rotation center of the trajectory of the X-ray sensor is never on the median sagittal plane defined by the patient positioned inside the apparatus and the trajectory is not symmetric to any of the possible sagittal planes of the patient.

Abstract: A method and apparatus for acquiring a radiographic image of a patient includes using an X-ray source and at least a X-ray detector supported in opposed positions, the area under investigation being positioned between the X-ray source and detector in the propagation bundle of the radiation emitted by the X-ray source, the X-ray source and detector being movable along a pre-set trajectory due to at least two movements. The X-ray dose administered to a patient can be adjusted automatically, dispensing the minimum dose necessary to achieve a radiographic image of good quality. The method and apparatus provide for performing a scout acquisition, preceding the acquisition of a real panoramic image, in a particularly efficient way. During the scout acquisition, data are collected for adjusting the X-ray dose for the following radiographic image acquisition.

Abstract: A painting apparatus for painting objects having three comparable dimensions includes a paint delivery system delivering paint supplied by an external system. The paint delivery system is supported by a carriage which, through an axle, moves on a guidance system having a shape that mimicks the shape of the object to be painted. The carriage is displaced along the guiding system by a controlled actuating system and the guidance system is optionally a hollow guide. A method for painting objects having three comparable dimensions is also disclosed.

Abstract: A method and apparatus for Cone-Beam Computerized Tomography, (CBCT) is configured to increase the maximum Field-Of-View (FOV) through a composite scanning protocol and includes acquisition and reconstruction of multiple volumes related to partially overlapping different anatomic areas, and the subsequent stitching of those volumes, thereby obtaining, as a final result, a single final volume having dimensions larger than those otherwise provided by the geometry of the acquisition system.

Abstract: A craniostat for an extraoral dental radiographic apparatus includes an upper portion connected to a lower portion by two rods. The upper portion includes a rest for a patient's forehead, wherein the rest for the patient's forehead rest has an arched shape vertically sliding in a suitable seat inside a crossbeam supported by the rods. A method of use of a craniostat according to the invention is also described.

Abstract: A camera hand-piece for medical use includes a lighting system, an optical window, a fixed part in turn having an optical system for acquiring images through an optical window, an image sensor, electronic circuits for image processing, and optionally a prism. The hand-piece has an external part, which is mobile with respect to the internal fixed part, and rotatably commutable between at least two different working positions having different optical or lighting features, which are freely selectable by an operator. In one embodiment, the lighting system for lighting the framed field is positioned in the internal fixed part of the camera hand-piece, and the mobile distal part, non comprising electronic parts, can be sterilized in an autoclave.

Abstract: A craniostat for an extraoral dental radiographic apparatus includes an upper portion connected to a lower portion by rods. The upper portion includes a crossbeam and rests for a patient's temples, the rests being formed by two arches articulated with the crossbeam. The arches lean on the patient's temples, and are blocked by a control system, which, in one embodiment, is configured as oscillating levers. The blocking action is caused by shape friction generated at the time of activation via the control levers. A method of use of a craniostat is also described.

Abstract: A craniostat for an extraoral dental radiographic apparatus includes a chin rest and a bite, which are optionally removable. The bite has centering surfaces of pre-defined orientation with respect to a centering position of the bite and is blocked in a blocking position by tightening the centering surfaces against tightening surfaces also having a pre-defined orientation with respect to the bite centering position, so that in tightened condition the bite is also automatically brought in correct centering position on the sagittal plane. A method of use of a craniostat is also described.

Abstract: A dental treatment unit includes n image-generating device, which is connected to a wearable electronic device having an image processor that receives images and displays them on a screen associated to the wearable electronic device. The wearable electronic device enables a visualization of diagnostic images or information of other kind coming from the image-generating device and/or from an operating unit on the screen of the wearable electronic device.

Abstract: An electrified rail for metal shelving units, the rail comprising a body of electrically insulating material, provided with longitudinal slots. Each slot having a wire of electrically conducting metal surrounded for more than 180° of its cross section by the walls of the respective slot, the remaining section of the wires being exposed for electric contact. The body of the rail being formed to allow transversal elastic deformation of the rail itself after the surrounding and holding of the wires the slots are open on a visible planar side of the rail body with longitudinal mouths having a width always inferior to the diameter of wires, the wires being held in slots by the monolithic body of the rail itself, while through the narrow mouths of said slots every electric wire can be reached by the devices mounted on the rail.

Abstract: Reinforced shelf for metal shelving unit, particularly for the shelving units whose shelves (B1, Bn) are provided, on the side facing the public, with electronic labels and/or other peripherals, and wherein the shelf on its bottom side has plate reinforcement (T1, Tn), parallel to each other and to the front and rear side (LA, LP) of the shelf itself, characterized in that in correspondence or at the ends of the reinforcements (T1, Tn) there are provided at least a pair of apertures (1, 10) for the passage and support of wiring (D), necessary to connect means (P1) on the rear side of the shelves, to means (P2) on the front side of the shelf (B1, Bn) for supporting and displaying goods. The apertures (1, 10) are sufficiently distant from the angular bent and ribbed areas of the reinforcements (T1, Tn) so as not substantially modify the characteristics of bend strength and torsion resistance of the reinforcements.
