A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

The present invention relates to pharmaceutical dosage forms, for example to a tamper resistant dosage form including an opioid analgesic, and processes of manufacture, uses, and methods of treatment thereof.

A method is provided for forming connections from reinforcing fibers between faces of a wall for a pressure container. The reinforcing fibers are gripped by tufting needles and are pushed through the faces, and loops are formed through which support elements are introduced. A corresponding method produces a pressure container.

A method of forming a three-dimensional object includes providing a carrier and an optically transparent member having a build surface. The carrier and the build surface define a build region therebetween. The method further includes filling said build region with a polymerizable liquid; continuously or intermittently irradiating said build region with light through said optically transparent member to form a solid polymer from said polymerizable liquid; applying a reduced pressure and/or polymer inhibitor-enriched gas to the polymerizable liquid through the optically transparent member to thereby reduce a gas content of the polymerizable liquid; and continuously or intermittently advancing (e.g., sequentially or concurrently with said irradiating step) said carrier away from said build surface to form said three-dimensional object from said solid polymer.

A mold for casting a micro-scale dry adhesive structure includes an upper surface including a first cavity having a first depth, a negative pattern for an array of micro-scale structures defined in a surface of the first cavity, and at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures, the at least one second cavity defining a negative pattern for a standoff of the micro-scale dry adhesive structure.

The invention relates to a production mold for a rotor blade of a wind turbine plant, having two mold half-shells (3, 4) which during a production method of the rotor blade are disposed so as to be at least temporarily beside one another, and having at least one inner walkway (2c, 2d) that runs along so as to be between the two mold half-shells (3, 4), characterized by at least one escape path (40) which runs along below at least one of the two mold half-shells (3, 4).

A composite rotatable assembly for an axial flow compressor comprises a spool having a plurality of blade assemblies arranged in stages on the spool and attached thereto by a wound band. Each blade assembly comprises a blade and a base, with the base having a forward tang extending axially forward of a leading edge of the blade and an aft tang extending axially aft of a trailing edge of the blade. The band is wound over at least a portion of the forward and aft tangs of the plurality of blade assemblies to hold the blade assemblies to the spool under centrifugal loading. An abradable layer may be added over the wound band.

A container manufacturing plant (10) includes an air circuit (78) employing a recycling method that includes at least the successive steps of: extracting filtered air from an oven (26), after the air has been used in the latter, for the purpose of cooling at least one part of the preforms; treating the sterilizing agent present in the extracted air resulting from the sterilization of the preforms; and recycling the extracted and treated air to the industrial area (16) where the plant (10) is installed. An air recycling method is also described.
