    Abstract: A dental abutment or mounting head features a base of predetermined size and shape arranged for seating atop a flanged portion of a transmucosal collar that is fastened to a dental implant. An axial hole opens into the abutment/head from the underside thereof at a location arranged to align over an axial bore of the collar through which the collar is fastened to the implant. An upper portion of the abutment/head for supporting a dental prosthetic or framework is customized for the patient concerned. The predetermined base portion occupies substantially the entire face of the collar flange to provide optimal support of the abutment/head. As an interface between the implant and the abutment, the collar avoids the need to customize the base of the abutment to fit the particular brand or model of implant used, thereby reducing the amount of custom design and/or fabrication needed to fit the application.

  • Patent number: 9484610
    Abstract: Processes for forming waveguides (200) using multiple co-planar layers of LTCC substrates (212, 212a, 212b) are described. Registration holes (222) on the substrates help align layering of the substrates. Arrays of circuit patterns are printed on each substrate, with each circuit being made up of conductor pattern (213) and/or via holes (224). Cavity alignment holes (226) formed around a periphery of each circuit allow alignment marks to be printed on the substrates for vision inspection. Similarly, circuit orientation holes (227) associated with each circuit allow orientation marks to be printed on the substrates to identify orientation of circuits in each finally formed waveguide. Substrate orientation holes (225) allow marks to be printed on one side of each substrate for alignment during screen printing. These in-process vision inspections and quality assurance tests allow product quality and process yields to improve.

  • Patent number: 9302946
    Abstract: The invention relates to a process for producing a ceramic matrix composite (CMC) part by infiltration of a suspension (S) of a ceramic powder into a fibrous reinforcement (14). A suspension (S) of ceramic powder containing particles of chosen particle size, dispersed in at least one solvent, is prepared. The infiltration of the suspension is carried out in a single step in the fibrous reinforcement (14) positioned between a mold (12) and a permeable membrane (16), which makes it possible to apply a vacuum (V) and to subsequently remove the solvent from the suspension through the permeable membrane (16). The invention applies to the production of large-sized parts of complex shape, in particular in the field of aeronautics and aerospace engineering.
