    CPC classification number: B24D9/085

    Abstract: A method for repositioning an abrasive disc within a repositionable abrasive disc mounting assembly is presented. The method includes mounting the abrasive disc to a repositionable abrasive disc mounting assembly in a first position. The mounting disc assembly includes the abrasive disc coupled to the back-up pad assembly such that the abrasive disc is in contact with a pressure feature of the back-up pad assembly, a drive shaft of a grinding tool, and a fastener that maintains the position of the abrasive disc and the back-up pad coupled to the drive shaft. The method also includes conducting an abrasive operation by activating the grinding tool. The method also includes re-positioning the abrasive disc, with respect to the repositionable abrasive disc mounting assembly, in a second position. The first position includes the abrasive disc in a first position relative to the pressure feature. The second position includes the abrasive disc in a second position relative to the pressure feature assembly. Re-positioning includes an adjustment between the first and second position while the abrasive disc is still positioned on the drive shaft between the fastener and the back-up pad assembly.

    Abstract: Electronic Devices Incorporating Flexible Component Layers with Interlocking Devices At least some aspects of the present disclosure directs to an electronic device 100 comprising a rigid member 100A, 100B, a flexible component layer 130, and an interlocking device 110A, HOB disposed between the flexible component layer and the rigid member. The flexible component layer has at least two sections when the flexible component layer is flexed. The interlocking device comprises a first interlocking component attached to or integrated with the flexible component layer, and a second interlocking component attached to or integrated with the rigid member configured to engage with the first interlocking component, such that the engagement prevents the separation of the flexible component layer from the rigid member along a direction generally perpendicular to a surface of the rigid member.

    IPC: B24D9/08

    Abstract: A repositionable abrasive disc mounting assembly comprises a backup pad and a clamp assembly. The backup pad has a rotational axis of use and a major surface with projections extending outwardly therefrom. The backup pad further comprises an inwardly facing centrally disposed first fastening member, and also an outwardly facing centrally disposed second fastening member. The clamp assembly comprises inner and outer clamp members for securing an abrasive disc. The inner clamp member comprises an inwardly facing centrally disposed third fastening member adapted to repositionably engage the second fastening member in a discrete number of rotational orientations. The inner clamp member further comprises an outwardly facing centrally disposed fourth fastening member. The outer clamp member comprises an inwardly facing centrally disposed fifth fastening member adapted to securely engage the fourth fastening member. A method of abrading a workpiece using the repositionable abrasive disc is also disclosed.

    Abstract: An orthodontic palatal expander may include a first shell configured to receive at least one tooth of a first posterior segment of a dental arch of a patient; a second shell configured to receive at least one tooth of a second posterior segment of the dental arch; and a split beam connected between the first shell and the second shell. The split beam may include a first beam comprising a relatively high modulus material, a second beam comprising the high modulus material, and a region between the first beam and the second beam.
