Abstract:

A method of manufacturing a staircase handrail volute, comprising the steps of: (a) cutting a workpiece from wood with a bandsaw such that the workpiece has an approximation of a shape of the volute, wherein the approximation dimensions are larger than the shape dimensions; (b) mounting the workpiece so that the workpiece may be operated on by a numerically controlled machine tool; (c) cutting a bottom surface of the workpiece to the shape dimensions with the machine tool; (d) cutting lower side surfaces of the workpiece with the machine tool to a first dimension between the approximation dimensions and the shape dimensions; (e) cutting the lower side surfaces of the workpiece with the machine tool to the shape dimensions; (f) drilling at least one mounting hole in the bottom surface with the machine tool, the at least one mounting hole for holding the workpiece in steps (g) through (j); (g) turning the workpiece over and mounting the workpiece so that the workpiece may be operated on by a numerically controlled machine tool; (h) cutting an upper surface of the workpiece with the machine tool to a second dimension between the approximation dimension and the shape dimension; (i) cutting upper side surfaces of the workpiece with the machine tool to the shape dimensions; and (j) cutting the upper surface of the workpiece to the shape dimensions with the machine tool. Other systems, devices and methods are disclosed.

Abstract:

A furan-based polyamide is prepared by the following steps: (1) preparing a furan-based oligomer of formula (1) HN—R—(NH—CO—F—CO—NH—R)—NH(1) where R is a hydrocarbon moiety and F is a furan (cyclo-CHO) moiety and n represents the average degree of oligomerization, and where n is within the range of 1 to 10 by reacting 2,5-furandicarboxylic acid or its derivative with a diamine at a temperature of at most 100 C.; (2) contacting the oligomer of step (1) with a bifunctional linker selected from an acid or a derivative thereof where the acid is furandicarboxylic acid or a non-aromatic dicarboxylic acid; provided that if the hydrocarbon moiety R is aromatic, then the bifunctional linker is an aromatic dicarboxylic acid or a derivative thereof, at a mole ratio of the oligomer to the difunctional linker within the range of 0.8 to 1.5 at polycondensation conditions, and (3) isolating the resulting polyamide.
