  • Patent number: 8986315
    Abstract: An aiming arm can include at least a pair of radiographic markers that define a first radiographic image characteristic when a radiographic image source is not adequately aligned with the aiming arm, and a second desired radiographic image characteristic when the radiographic image source is adequately aligned with the aiming arm. Once the radiographic image source has been aligned with the aiming arm, the position of the aiming arm relative to an underlying implant can be visually inspected to determine whether the aiming arm is aligned with the underlying implant.

  • Patent number: 8505517
    Abstract: The present invention relates to a method for reintroducing exhaust gas to the intake of an internal-combustion engine wherein, during the engine exhaust phase, part of the exhaust qas contained in combustion chamber (60) of cylinder (10) of the engine is fed, for an operating range of this engine, into a first fluid circulation circuit (C1) and the other part of said gas is discharged into an exhaust circuit. According to the invention, the method consists: during the engine intake phase, in cooling the exhaust qas fed into fluid circulation circuit (C1), in mixing the cooled recirculated exhaust qas with fresh supply air (AF) coming from engine supply circuit (44), in feeding the mixture of recirculated exhaust gas and of supply air into a second fluid circulation circuit (C2), and in cooling said mixture fed into second circuit (C2) prior to feeding it into combustion chamber (60).

  • Publication number: 20120303037
    Abstract: Provided are distal aiming assemblies useful in aiming fixation members for insertion into an intramedullary device, such as a nail. The assemblies include a spring that flexibly connects an elongate arm to a base. The spring enables deflection of the elongate arm to compensate for curvature of the intramedullary device when inserted into a bone, in turn enabling the user to accurately install fixation members into the intramedullary device through the deflected elongate arm.
