    摘要： The invention relates to a method for processing an optically reactive material, comprising: providing a starting material (3), which is optically reactive and fills a working volume (2); and optically processing the starting material (3) in the working volume (2) by means of irradiation of light of a first wavelength and of a second wavelength, wherein the light of the first wavelength and of the second wavelength is provided by a lighting device and at least one material property of the starting material is changed by means of the optical processing and the optical processing comprises the following: irradiating a first partial layer volume of the working volume (2) filled with the starting material (3) using the light of the first wavelength; irradiating the first partial layer volume of the working volume (2) using the light of the second wavelength, wherein the light of the second wavelength is projected into the working volume (2) by means of a projection device (7) capturing only the first partial layer volume wholly or partially; irradiating a second partial layer volume of the working volume (2) filled with the starting material (3), which is different from the first partial layer volume, using the light of the first wavelength; irradiating the second partial layer volume of the working volume (2) using the light of the second wavelength, wherein the light of the second wavelength is projected into the working volume (2) by means of the projection device (7) capturing only the second partial layer volume wholly or partially; and repeating the preceding steps for layer-by-layer optical processing of the starting material (3) in the working volume (2) until a volume of the starting material (3) to be processed, which captures the working volume (2) wholly or partially, is optically processed. Furthermore, a device for processing an optically reactive material is provided.

    摘要： A noise and vibration attenuation panel for a structure within a propulsion system includes a first plurality of unit cells and a first plurality of mass elements disposed within the first plurality of unit cells. The first plurality of unit cells include a first periodic structure having a first unit cell, a second unit cell, a third unit cell, and a fourth unit cell, each of the first unit cell, the second unit cell, the third unit cell and the fourth unit cell including a central body interconnected via a plurality of lateral tubes extending from the central body, the first periodic structure forming a first lateral layer of unit cells. The noise attenuation panel can simultaneously control acoustic waves or energy (i.e., via noise attenuation flow paths) and vibration (i.e., via the mass elements).

    摘要： A curb former (10) includes a rotatable drive shaft (20), a gutter drum (80), and a curb profiling drum (100). The gutter drum (80) is secured to the drive shaft (20) such that the drive shaft (20) and gutter drum (80) rotate together. The curb profiling drum (100) is detachably secured relative to both the drive shaft (20) and the gutter drum (80). This configuration allows one curb profiling drum (100) to be replaced with another curb profiling drum (100) to change the profile of a curb resulting from a curbing operation using the curb former (10).
