Abstract: A static sealing device for a wheel hub comprising an inner ring associated with an outer ring of a constant velocity joint coupled with the wheel hub. A first sealing assembly is integrated between the inner ring and an outer ring of the wheel hub to protect respective rolling bodies. A second sealing assembly is integrated between the wheel hub and the outer ring of the joint. The first sealing assembly includes a shield fitted to the inner ring with a sleeve portion thereof and a flange portion extending towards the joint carrying an annular signal generating element and a tubular support element which projects axially from the flange portion. The second sealing assembly includes a tubular core having opposite ends embedded in an elastomeric material forming a sealing lip towards the joint and an elastically deformable annular tooth for engaging with a complimentary feature of the tubular support element.

Abstract: A static sealing device for a wheel hub assembly, an inner ring of which is operatively associated with a constant velocity joint, an outer ring coupled with the wheel hub, including a first sealing assembly arranged between the inner ring and an outer ring of the wheel hub for protecting respective rolling bodies, and a second sealing assembly supported by the inner ring, arranged straddling the wheel hub and the outer ring; wherein the first sealing assembly includes a shield anchored to the inner ring of the bearing and provided, on a first side of the joint, with a flange portion carrying an annular signal generating element towards the joint which leaves an annular radially inner area of the flange portion uncovered, defining an annular seat between it and the inner ring in which an edge radially folded on the outside of a tubular core of the second sealing assembly.

Abstract: This system, valid for any type of lamp (both those with a filament and those with a gas discharge), permits the continuous control and regulation, on a distribution network, of the luminous flow of each single lamp that is connected to it in parallel. The system, as can be seen in FIG. 1, is characterised by two sections, one inserted at the beginning of the branching of the distribution network, the “General Control Module”, and one inserted on each single lamp, the “Module of Control and Regulation of the Luminous Flow”, whose functions can be synthesised thus: 1. The “MODULE OF CONTROL AND REGULATION OF THE LUMINOUS FLOW” is a regulator of partialisation of phase that, thanks to a specific electronics of elaboration, runs the lamp connected to it, so that this operates with the programmed functional parameters. 2.

Abstract: An electric control system for a pulse width modulated inverter connected in parallel to an electricity distribution network for correcting or minimizing a voltage total harmonic distortion of the distribution network includes a sampler of the voltage of the electricity distribution network for obtaining samplings of the distribution network. The sampler preferably is an analog-to-digital converter. The system also includes a phase locked loop circuit that supplies a phase value of a period under examination, and a storage system for coupling the various samplings with the phase value obtained by the phase locked loop circuit.

Abstract: A wide range of electric loads, has functional concepts hat lie outside the common standards (resistive, inductive, capacitive), as, for instance: gas-discharge lamps, or electronic loads; in fact, for their own functional features, these loads, introduce some harmonic distortions on the absorbed current, that cannot be solved with normal compensating systems (as, for example, phase advancers). A disadvantage which affects the feeders and their respective generators, therefore reducing: their efficiency, the power capacitance that can be supplied, and the qualitative level of energy distribution. Our system succeeds in evaluating and compensating (for the part of energy that its power section allows), the harmonic distortion on the network, therefore improving the various parameters which characterize it.
