Abstract: The present invention provides a supporting hook structure, comprising a sleeve, a fixing rod, a first limit unit, a hook and a fixing device. The fixing rod is connected to the side surface of the sleeve. The hook body is connected to one end of the sleeve. The first limit unit is arranged on the side surface of the sleeve and adjacent to the hook body. The first limit unit makes the hook body rotates with the axis direction of the sleeve as a rotation axis. The fixing device is connected to the other end of the sleeve to fix the rotating position of the hook body. Through the above, the hook part enters the proximal thigh from a surgical entrance and the hook part rotates to make the hook part abut against the proximal femur to complete the positioning and fixation of the femur hook structure to the femur.

Abstract: A novel additive for recycling thermoset materials, its related recyclable thermoset composition and its application are disclosed. Specifically, the composition of the additive comprises at least one copolymer that has at least one carbamate group, at least one carbonate group and/or at least one urea group, and a number-average molecular weight of the copolymer is between 100 and 50,000 Da.

Abstract: A method to determine the shape data of a complex curve surface using reference templates from a copy of the workpiece before it was used and the undamaged portion of the used workpiece so that the damaged portion of the workpiece can be reconstructed. The reference template is scanned in layers, including the portion corresponding to that which has been damaged in the workpiece, as well as adjacent undamaged portions of the used workpiece. Offsets of the reference template and workpiece are generated, based on corresponding portions of the reference template and the used workpiece. A new set of offsets of the damaged portion of the workpiece is then calculated. This calculated set of offsets is then used to calculate further profiles until a complete profile of the damaged portion has been predicted.

Abstract: A system is provided for finishing a surface of a workpiece, for instance by abrading a brazed area or welded area to remove excess brazed or weld material during the refurbishment of the turbine blade. A real-time control system has a controlled material removal rate strategy where a computer controls the different contact or polishing forces in real-time to achieve high accuracy.

Abstract: A reference template is used to help in the reconstruction of a damaged workpiece, such as a turbine blade. The reference template is a copy of the workpiece from before it was used. The reference template is scanned in layers, including the portion corresponding to that which has been damaged in the workpiece, as well as adjacent undamaged portions. The adjacent undamaged portions of the workpiece are also scanned as layers. Profiles of the layers of the reference template and workpiece are generated, based on the scans. Sets of offsets are then determined based on corresponding points within adjacent scanned layers in the undamaged portion of the workpiece and the corresponding portion of the reference template and also within the portion of the reference template corresponding to the damaged portion of the workpiece.
