Abstract:
Die Erfindung bezieht sich auf einen flexibler Schüttgutbehälter mit einem von Wandungen umgrenzten Behälteraufnahmeraum, wobei die Wandungen zumindest bereichsweise aus einem mehrschichtigen Folienmaterial (Multilayer) aufgebaut sind und zumindest zwei Folienschichten aus einem Kunststoffmaterial bestehen, zwischen denen eine Schicht und/oder eine Einlage aus einem elektrostatisch ableitfähigen Material eingebettet ist und zumindest die dem Schüttgut zugewandte innere Folienschicht aus dem Kunststoffmaterial mit einer an die Schicht und/oder Einlage aus dem elektrostatisch ableitfähigen Material mündenden Perforation versehen ist. Um diesen weiter zu verbessern ist vorgesehen, dass die Perforation als Laserperforation ausgebildet ist mit einem Perforationslochmuster, bei dem sich ein jeder Lochkanal im Querschnitt von der dem Schüttgut zugewandten Innenseite der inneren Folienschicht zu der Schicht und/oder der Einlage aus dem elektrostatisch ableitfähigen Material hin verjüngt.
Abstract:
A system is disclosed for use in additively manufacturing a composite structure. The system may include a head having a nozzle configured to discharge a composite material, including a matrix and a continuous reinforcement. The system may also include a cure enhancer configured to enhance curing of the matrix, and a support configured to move the head during discharging to create a structure having a three-dimensional trajectory. The system may further include a cutting mechanism operatively mounted to at least one of the head and the support, and configured to sever the continuous reinforcement after discharge from the nozzle. The cutting mechanism may include a blade, and an ultrasonic energy source connected to the blade.
Abstract:
A method of laser processing a laminate workpiece stack (110) includes forming a contour line in a first transparent workpiece (112a) of the laminate workpiece stack (110) having a resin layer (120) disposed between the first transparent workpiece (112a) and a second transparent workpiece (112b). Forming the contour line includes focusing a pulsed laser beam (152) into a pulsed laser beam focal line directed into the first transparent workpiece (112a) to generate an induced absorption within the first transparent workpiece (112a) and translating the pulsed laser beam focal line along a first workpiece separation line, thereby laser forming the contour line having a plurality of defects. The method also includes separating the resin layer (120) along a resin separation line by focusing the pulsed laser beam (152) into the pulsed laser beam focal line directed into the resin layer (120) and translating the pulsed laser beam focal line along the resin separation line, thereby laser ablating the resin layer (120).
Abstract:
A method to join electrochemical cell members comprising an inorganic material by laser. The method includes the steps of positioning the electrochemical cell members to each other, defining the constituents of the joining process, utilizing a laser system to generate a laser beam, focusing the laser beam spot on the electrochemical cell members, and establishing the joint by producing joint segments in a defined joining sequence. The joining method allows to produce gastight, high-temperature resistant connections between electrochemical cell members.
Abstract:
This document describes techniques and apparatuses for attaching electronic components to interactive textiles. In various implementations, an interactive textile that includes conductive thread woven into the interactive textile is received. The conductive thread includes a conductive wire (e.g., a copper wire) that that is twisted, braided, or wrapped with one or more flexible threads (e.g., polyester or cotton threads). A fabric stripping process is applied to the interactive textile to strip away fabric of the interactive textile and the flexible threads to expose the conductive wire in a window of the interactive textile. After exposing the conductive wires in the window of the interactive textile, an electronic component (e.g., a flexible circuit board) is attached to the exposed conductive wire of the conductive thread in the window of the interactive textile.
Abstract:
Apparatuses and embodiments related to compensated laser cutting of labels. A computer system receives an image of a label, and rasterizes the image. The computer system determines how much of each type of printer ink of a label printer to deposit at each pixel location of the image. The computer system determines which pixels intersect a cut line, and determines the characteristics of the ink of the pixels, such as the quantity or thickness of the ink at the pixel locations. The computer system determines laser data including power, cut speed, and/or frequency of a laser that is tuned to accurately cut through the ink that forms the image, the material(s) of the label, and the adhesive that removably adheres the label to base material(s), but to not excessively damage the base material(s). A laser cutting system uses the laser data to control a laser.
