摘要： An optical unit has an optical element reflecting light between intersecting first and second directions, and a holder. The holder includes a holder body extending in a third direction intersecting the first and second directions, and a pair of surface portions extending from the holder body in an intersection direction intersecting the third direction. The optical element is arranged between the surface portions. At least one surface portion has an inner surface facing the optical element, an end surface connected to an edge of the inner surface in an intersection direction, and a concave portion arranged astride the inner and end surfaces and recessed in the intersection direction from the end surface. The concave portion accommodates an adhesive member bonding the optical element with the holder. The length of the concave portion along the end surface is greater than the depth of the concave portion in the intersection direction.

摘要： A method of fastening a second object to a fiber composite part including a structure of fibers embedded in a matrix material includes: providing the fiber composite part including an attachment surface, with a portion of the structure of fibers being exposed at the attachment surface; providing the second object; placing the second object relative to the fiber composite part, with a resin in a flowable state between the attachment surface and the connector; pressing the second object and the fiber composite part against each other and causing mechanical vibration to act on the second object or the fiber composite part or both, thereby causing the resin to infiltrate the exposed structure of fibers and activating the resin to cross-link; whereby the resin, after cross-linking, secures the second object to the fiber composite part.

摘要： Disclosed is a method of curing a composite article and associated curing apparatus. A heat source is provided for heating the composite article. A temperature related property is detected proximal to the heat source and the heat output is regulated to a predetermined temperature vs. time profile. Heat output vs time data is acquired and functionalised and the curing completion time is determined based on the functionalised heat output vs time data.
The method provides for heating a composite article so as to follow a predetermined temperature vs. time profile (i.e. a cure profile) and avoid excessively high temperatures. The required heat output vs time has also been found to be broadly reproducible, and the curing completion time can be more readily determined from functionalised heat output vs time data, for example by identifying reproducible characteristics of the functionalised data.-

摘要： This disclosure provides a method of recycling heat during operation of a plant in which equipment for processing at least two different materials is co-located. The method comprises a first process for processing a first material and a second process for processing a second material. The second material has a melting point that is less than a melting point of the first material. During the first process, the first material is subjected to a first melting process and then subjected to a first cooling process that includes solidification of the first material. During the second process, the second material is subjected to a second melting process and then subjected to a second cooling process that includes solidification of the second material. The method comprises recovering heat from the first cooling process and using at least some of the heat as a heat source for the second melting process.

摘要： Non-destructive evaluation (NDE) systems and methods are provided for monitoring objects being manufactured during a cure or consolidation process and for detecting defects that occur during the cure or consolidation process or to detect conditions of the process that can lead to the occurrence of defects. Information acquired by the NDE system during the cure or consolidation process can be used to adjust one or more parameters of the process in real-time to prevent defects from occurring or to reduce the number and/or severity of defects that occur during the cure or consolidation process.

摘要： A sealable container comprising: a base having a geometric shape; sides extending from the base and defining a mouth opposite the base, wherein cross-sections of the sides parallel to the base have a geometric shape; and a seal of the mouth comprising: a first zipper member and a second zipper member, wherein when the seal is closed to seal the mouth the first and second zipper members engage each other to make the seal and when the seal is open the first and second zipper members disengage to break the seal, wherein the base, sides and seal comprise silicone, wherein the base and at least a portion of the sides adjacent the base are of sufficient thickness and rigidity for the container to freely stand vertically on its base with the mouth at the top, and wherein the seal and at least a portion of the sides defining the mouth are sufficiently flexible to allow the seal and side portion to be deformed between open and closed mouth configurations.
