This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

The present invention provides for concentrated aqueous silk fibroin solutions and an all-aqueous mode for preparation of concentrated aqueous fibroin solutions that avoids the use of organic solvents, direct additives, or harsh chemicals. The invention further provides for the use of these solutions in production of materials, e.g., fibers, films, foams, meshes, scaffolds and hydrogels.

Described are polymer compositions that include a blend of copolyester polymers based on monomers that include on terephthalic acid (TPA), isophthalic acid (IPA) and 1,4-cyclohexanedimethanol (CHDM), wherein the blend includes a first copolyester that is semi-crystalline and a second copolyester that is amorphous; and films made from the polymer compositions useful for transparent high temperature conductive film applications.

An absorbent body forming satisfactory connections while webs are conveyed at a high speed includes at least two sheets of nonwoven fabric overlapping each other; connections at which the nonwoven fabric sheets are connected together; and an absorbent material disposed between the nonwoven fabric sheets at a small region encircled by the connections. When seen in a direction perpendicular to a main surface of the nonwoven fabric sheets, a plurality of the connections is formed with spaces therebetween on each side of imaginary polygons compartmentalizing the nonwoven fabric sheets and neighboring each other, and the connection is formed at least on a middle part of the sides common to the imaginary polygons neighboring each other. The connections are formed sequentially, and simultaneously arranged in a row parallel to each other, and the minimum number of connections per row is at least 45% of the maximum number of connections per row.

A polymer board with a cut edge is automatically advanced through a stationary, non-spinning sealing element that contacts and compresses the cut edge and provides a sealed and smooth surface to the cut edge.

An additively manufactured component includes a planar sheet and a coating applied to the planar sheet to form the component. The component is configured for attachment to a non-planar surface of a workpiece.

One aspect of the present disclosure relates to devices for sealing gaps in an extrusion assembly to provide for a consistent extrusion. In one embodiment, a barrel-shaped sealing device with a resilient protruding edge is used to prevent extrusion material from entering gaps between the piston and the inner surface of the barrel. The sealing device includes a fastener to releasably attach the sealing device to the piston. Sealing rings are inserted into a bottom gap formed between the bottom edge of the barrel and the bottom surface of the die.

Disclosed is a method for connecting a connecting face of an edge material to a connecting face of a workpiece by a synthesis element, including the steps: of making available the workpiece, feeding the synthesis element, which is made available by at least one function film composed of an adhesive, activating the adhesive function film, applying the synthesis element to one of the connecting faces, connecting the synthesis element to the other of the connecting faces, wherein the workpiece and the edge material are connected by the synthesis element located between them. Furthermore, there is disclosed a synthesis element and a device for connecting a connecting face of an edge material to a connecting face of a workpiece.

The present application provides a calender, a floor production line and a production method using the calender, wherein the calender comprises a calendering roller rack and a set of calendering rollers arranged on the calendering roller rack. The set of calendering rollers comprises a plurality of calendering rollers arranged in a line and not vertically. The present application changes the arrangement of the calendering rollers. The calendering rollers are arranged in a line, not vertically. This arrangement reduces the overall height of the calender, decreases the requirements of the calender on the height of the factory building and facilitates long-distance transportation by containers. Using the calender to assemble the floor production line, the height space of the factory building occupied by the production line can be saved.

A blister packaging machine includes: a pocket portion forming unit that forms a pocket portion having a bottom portion and a side portion, in a belt-like container film, and adjusts balance between a thickness of the bottom portion and a thickness of the side portion; an illumination device that is disposed on a downstream side of the pocket portion forming unit, and irradiates the pocket portion with an electromagnetic radiation; an imaging device that is disposed on a side opposite to the illumination device across the container film, and obtains transmitted image data based on the electromagnetic radiation transmitted through the pocket portion; a side portion state detector that detects a state of the thickness of the side portion based on the transmitted image data; and a controller that controls an operation of the pocket portion forming unit.
