Abstract: Circuits arranged to produce first and second outputs produced by first and second switch-mode converters, respectively, wherein each switch-mode converter comprises a converter input, a converter output, a converter controller, a converter controller enable input arranged to provide power to the controller, and a semiconductor power switching device coupled between the converter input and the converter controller. A first output of the first converter and a second output of the second converter are each arranged to produce a voltage of higher magnitude than the voltage at the respective converter controller enable input and converter input when the converter controller is enabled. Methods of controlling first and second outputs from first and second switch-mode converters are also disclosed.

Abstract: The invention relates to a process for preparing a rare-earth organophosphate in the form of a fluid or not very viscous solution that can be used as is for the preparation of a “preformed” catalyst system intended, in particular, for the cis-1,4 stereospecific polymerization of conjugated dienes.

Abstract: Motorized hub for an electrically powered motor vehicle comprising a wheel hub mounted to rotate about a hub axis, and an electric traction unit comprising an external stator connected to a hub carrier and an internal rotor (31) whose axis of rotation is distant from the hub axis. The motorized hub comprises reduction means acting between shaft (33) of rotor (31), friction braking means, and a braking rotor secured to the hub. The reduction means comprise a drive pinion connected to the rotor (31) and a ring gear connected to the hub. A brake shaft passes through the hub carrier to connect the braking rotor to the hub. The reduction means comprise two reduction stages and the hub is mounted so that it can rotate via rolling-contact hub bearings positioned around a stub axle of the hub carrier, the brake shaft passing axially through a cavity of the stub axle.

Abstract: During the process for production of a rubber mass the rubber mass is mixed in a mixing tank (12); then, the mixing of the rubber mass is interrupted; then, with the mixing stopped, the tank (12) is opened by displacing a door (18) for shutting of an opening (16) for discharge of the rubber mass from the tank (12), according to an opening trajectory between a position of shutting of the opening (16), towards a position of release of the opening (16); the positions of shutting and release corresponding to the ends of the opening trajectory; then, with the tank (12) open, the mixing of the rubber mass is restarted when the door (18) is in a predetermined intermediate position of its trajectory between the positions of shutting and release.

Abstract: Machine for the additive manufacture of a three-dimensional object by sintering or melting powder using a beam of energy acting on a layer of powder in a working zone, the said working zone being defined in the upper part of a build sleeve fixedly mounted in a chassis, in which sleeve the said object is manufactured, the said object being supported by a build plate which slides inside the said build sleeve when driven in vertical translation by the head of an actuating cylinder placed along the central axis of the said sleeve.

Abstract: A method for determining the aerodynamic moment of resistance Maero-EM of a wheel arranged on an axis, by measuring the value of the mechanical power Pm to be applied to the wheel in order to maintain it in rotation at a constant speed ?, the said wheel being equipped with a rotational-drive means and with a device for picking off and/or recording the numerical values of the said mechanical power and those of the rotational speed. The wheel is protected by a removable cap and is subjected to a flow of air.

Abstract: Disclosed is a tire mountable apparatus and methodology for mounting devices within a tire. In certain embodiments a signal generator may be mounted to the tire to generate signals based on changes in the radius of curvature of a tire. A piezoelectric sandwich and/or a substrate is/are provided having a length and width based at least in part on tire dimensions and positioned in the tire such that the longer length dimension is positioned laterally with respect to the width of the tire. The sandwich and/or substrate is/are sized such that the width dimension provides substantially no response to changes in the circumferential radius of curvature of the tire so that the length dimension defines the primary bending direction while the width dimension provides a strain free mount for associated devices.

Abstract: A system is provided for producing hydrogen and oxygen based on decomposition of sodium chlorate (NaClO3). In a service station, NaClO3 is produced by a sodium chloride (NaCl) electrolyser. The service station is supplied with water (H2O), NaCl, and energy in order to carry out an electrolysis reaction in the electrolyser, to produce NaClO3 and gaseous hydrogen (H2). The NaClO3 and H2 are supplied to vehicles. Each vehicle includes a reactor for decomposing the NaClO3 and producing reaction products of NaCl and oxygen, with the oxygen being supplied to a fuel cell.
