摘要： A hermetically sealed filtered feedthrough assembly attachable to an AIMD includes an insulator hermetically sealing a ferrule opening of an electrically conductive ferrule with a gold braze. A co-fired and electrically conductive sintered paste is disposed within and hermetically seals at least one via hole extending in the insulator. At least one capacitor is disposed on the device side. An active electrical connection electrically connects a capacitor active metallization and the sintered paste. A ground electrical connection electrically connects the gold braze to a capacitor ground metallization, wherein at least a portion of the ground electrical connection physically contacts the gold braze. The dielectric of the capacitor may be less than 1000 k. The ferrule may include an integrally formed peninsula portion extending into the ferrule opening spatially aligned with a ground passageway and metallization of an internally grounded feedthrough capacitor. The sintered paste may be of substantially pure platinum.

摘要： The present invention relates to a method of producing a composite rod from a braze material and a sheet of material comprising cermet. The method comprises scoring a surface of the sheet to produce at least one line of localised stress and subsequently causing the sheet to break along the line of localised stress, thereby to produce a plurality of cermet chunks. The cermet chunks can be combined with the braze material to produce the composite rod. In a particular embodiment, the sheet of material may be a used cermet cutting tip.

摘要： The present invention relates to a method of manufacturing a component 1 by additive manufacturing. The method comprises providing a work surface 2 on which the component 1 is to be manufactured, and providing at least one deposition material 3 from which the component 1 is to be composed. The deposition material, typically in the form of wire, is advanced to a localized deposition area 4 where it is added to the component 1 being manufactured. The method further comprises focusing at least one light beam 5 of incoherent light emitted from at least one heating source 6 in the deposition area 4 so that the deposition material 3 is deposited for building up the component 1. At least one light focusing mirror 7 and/or lens 11 is used to focus the incoherent light in the deposition area 4. The invention further relates to the use of such a method in space, such as on a space station, on a space craft or on parabolic flights for testing.
