| 20100115768 | METHOD FOR ADAPTING AN ELECTRONIC COMPONENT FOR SURFACE MOUNTING - The invention relates to a method for adapting an electronic component with leads that are not suited to surface mounting on an electrical circuit. The method includes a step of bending said leads. The bending step shapes the leads of said component so that they are suitable for mounting on the surface of the electrical circuit. In particular, the invention applies to electronic components such as radio frequency and microwave power transistors, marketed notably in a straight-lead version. | 05-13-2010 |
| 20100194490 | Microstrip Technology Hyperfrequency Signal Coupler - The present invention relates to a power coupler for hyperfrequency signals. The single-section coupler with microstrip lines comprises a dielectric substrate, a main line and a secondary line comprising a coupling section, the lines being deposited on the substrate, the main line being substantially rectilinear and uniform over its entire length, the coupling section comprising a protuberance at each of its ends, the protuberances being interlinked by a portion of conductive line of which the section, the shape and the disposition are adapted to minimize the coupling between said portion and the main line relative to the coupling made between the protuberances and the main line. The invention applies notably to the measurement of the power of a signal passing through a transmission line. | 08-05-2010 |
| 20110109417 | POWER TRANSFORMER FOR RADIOFREQUENCY SIGNALS - The present invention relates to a power transformer for radiofrequency signals. The transformer is made in a low-cost, multilayer printed circuit board comprising at least the following stacked layers in succession: a first conductive layer, a first layer of dielectric substrate, a second conductive layer, a second layer of dielectric substrate, and a third conductive layer, the primary winding being formed by a turn printed in the second conductive layer, the secondary winding being formed by a first turn printed in the first conductive layer, this first turn being connected to a second turn printed in the third conductive layer, the turns of the secondary winding being placed opposite to the turn of the primary winding, the board being tightly held above and below by two plates of ferromagnetic material. Capacitive components connected between winding(s) on the one hand and ground on the other hand can improve the behavior of the proposed transformer. The invention applies notably to the production of HF transmitting radioelectric terminals. | 05-12-2011 |

| 20120034829 | MARINE ENGINE LUBRICATION - Trunk piston marine engine lubrication, when the engine is fueled by heavy fuel oil, is effected by a composition comprising a major amount of an oil of lubricating viscosity containing at least 50 mass % of a Group II basestock, and respective minor amounts of an overbased metal hydrocarbyl-substituted hydroxybenzoate detergent other than such a detergent having a basicity index of less than two and a degree of carbonation of 80% or greater and 5 to 500 mass %, based on the mass of the detergent, of an oil-soluble alkyl-substituted phenol other than a hindered phenol. Asphaltene precipitation in the lubricant, caused by the presence of contaminant heavy fuel oil, is prevented or inhibited. | 02-09-2012 |

| 20090093387 | Lubricating Oil Composition - A lubricating oil composition comprising a Group II basestock and a neutral or overbased metal hydrocarbyl-substituted hydroxybenzoate detergent having a basicity index of less than 2. | 04-09-2009 |
| 20100062957 | Method of Reducing Asphaltene Precipitation in an Engine - A method of reducing asphaltene precipitation or ‘black paint’ in an engine is disclosed. The method includes the step of lubricating the engine with a lubricating oil composition comprising: an oil of lubricating viscosity in a major amount; and, a salicylate detergent system in a minor amount comprising one or more neutral or overbased alkaline earth metal C | 03-11-2010 |
| 20100062958 | Detergent - A detergent including one or more neutral or overbased alkaline earth metal C | 03-11-2010 |
| 20110245120 | Lubricating Oil Composition - A lubricating oil composition having a phosphorus content of up to 0.12 wt %, a sulfated ash content of up to 1.2 wt % comprising (a) a major amount of an oil of lubricating viscosity; (b) an alkali metal or alkaline earth metal alkyl salicylate lubricating oil detergent providing from 7-15 mmol salicylate soap per kilogram of lubricating oil composition; (c) one or more dispersants providing the lubricating oil composition with from at least 0.12 wt % to 0.20 wt % atomic nitrogen, based on the weight of the lubricating oil composition, and (d) a dispersant-viscosity modifier. | 10-06-2011 |

| 20110100640 | DRIVE MECHANISM - A drive mechanism is described for moving/controlling objects/mechanisms/systems coupled with a drillstring and/or pipe. The drive mechanism may be axially arranged on a drillstring or pipe, compact, capable of fine control and delivering high torque or the like and may be electrically and/or hydraulically powered. The drive mechanism may comprising a driving member comprising a plurality of drivers linearly translatable with respect to the driving member, each driving member having at their ends a male engaging portion and an associated driven member, comprising a plurality of female receiving portions adapted to receive a male engaging portion, the arrangement being such that linear translation of a driver causes its engaging portion to engage with a female receiving portion and the action of the engaging portion produces a reaction in the receiving portion causing displacement of the driven member in a direction other than that of the translatable driver. | 05-05-2011 |
