An embodiment comprises a container to include a substrate during processing (e.g., centrifugal or vibratory processing) and protect the substrate from other substrates (e.g., medical implants) that are simultaneously being processed and/or from the polishing environment (e.g. vibratory tub sidewalls) during processing. Other embodiments are described herein.

A drag and/or dip finishing machine has at least one workpiece holder for the releasable fastening of the workpieces to be machined and a container, disposed beneath the workpiece holder, for accommodating the grinding and/or polishing granules, wherein the workpiece holder and the container are movable relative to each other in that at least the container is rotationally driven. The container has a chamber, which extends around the whole of the periphery thereof and is fluidically connected to the inside, accommodating the grinding and/or polishing granules, of the container, at least on a lower portion thereof, the chamber being equipped with a liquid discharge unit in order to be able to discharge the machining agent from the chamber in the event of an excess of machining agent in the container.

The present invention provides a uni-compartmental knee joint prosthesis (1) which includes a tibial component (2) and a femoral component (3). The tibial component (2) has a fixation portion (10) adapted to be fixed to an upper end of a prepared tibia (T) in a patient, and a bearing portion (30) presenting an articulation surface (32) formed from a ceramic material, wherein the bearing portion (30) is adapted for movement relative to the fixation portion (10). The femoral component (3) is adapted to be fixed to a lower end of a prepared femur (F) in a patient, and comprises a body portion (50) presenting an articulation surface (56) formed from a ceramic material for engagement with the articulation surface (32) of the tibial component (2). The articulation surfaces (32, 56) of the tibial and femoral components are adapted for essentially congruent engagement over a full range of movement of the prosthesis.

An apparatus (1) for polishing cavities in mechanical components (4), characterized in that said apparatus (1) comprises a supporting framework (2) supporting a working plane (3) thereon are housed the mechanical workpieces (4) to be subjected to the polishing process, said mechanical workpieces (4) being clamped to said working plane (3) by clamping means (5), said apparatus further comprising vibration generating means (6) cooperating with resilient components (7) adapted to transmit a vibration motion and amplify the action of said vibrating means (6), said apparatus (1) comprising furthermore a closed loop distributing system for distributing a mixture (8) containing a polishing and buffing cleansing material and a micro-abrading material, said mixture (8) being fed within said mechanical workpieces (4) together with metal bodies (9) having a ball shape and a different size and mass, adapted to move and stir said mixture (8) against the inner walls of the cavity of said mechanical workpieces (4) being processed.

A vibratory tumbler. The vibratory tumbler includes a bowl having one or more engagement hooks and a latching hook; a base; and a connection platform coupled to the base and removably coupled to the bowl. The connection platform further comprises a vibration source; one or more openings capable of engaging the one or more engagement hooks; and a locking mechanism capable of engaging the latching hook. The locking mechanism can further comprise a latching opening capable of receiving the latching hook; a spring clip substantially within the latching opening and capable of engaging the latching hook; and a locking lever rotatably coupled to the spring clip whereby the spring clip engages the latching hook when the locking lever is in a locked position and releases the latching hook when the locking lever is in an unlocked position.

Various examples are provided for hybrid tools including fixed-abrasive and loose- abrasive phases. In one example, a hybrid tool for finishing an internal surface of a workpiece includes a metallic rod and magnetic abrasive bonded to one or more defined portions of the metallic rod by an adhesive that dissolves when n contact with a lubricant used to finish the internal surface of the workpiece. In another example, a method for finishing an internal surface of a workpiece includes mounting the workpiece in a chuck of a lathe; positioning a hybrid tool inside an internal cavity of the workpiece using one or more pole-tips; providing an amount of the lubricant to the internal cavity; and rotating the workpiece with the lathe while controlling positioning of the hybrid tool inside the internal cavity using the one or more pole-types.

A fluid clean apparatus includes a container that has an opening for loading metal parts therein, and an internal loading platform system that includes a platform that is positioned inside the container, and a lift cylinder that is coupled to the platform and raises up and down the platform.

A method for manufacturing a display device includes forming a first gate metal wire on a substrate, forming a first insulation layer that covers the first gate metal wire, forming a second gate metal wire on the first insulation layer, forming a second main insulation layer that covers the second gate metal wire, forming a second auxiliary insulation layer on the second main insulation layer, forming an exposed portion of an upper surface of the second main insulation layer by polishing the second auxiliary insulation layer, and forming a first data metal wire on the second main insulation layer and the second auxiliary insulation layer.
