Methods for assembling rotor blades are provided. A method includes receiving a first portion of a rotor blade at an erection site. The method further includes receiving a second portion of the rotor blade at the erection site. The method further includes aligning the first portion and the second portion at the erection site, the first portion and the second portion supported on a fixture system when aligned. The method further includes connecting a blade component of the first portion and a blade component of the second portion together at the erection site.

The invention relates to a process for bonding a silicone or silicone based material to a polyurethane and use of the bonded silicone-polyurethane in the manufacture of biomaterials, devices, articles or implants, in particular long term implantable medical devices in the fields of cardiology, orthopaedics, plastic surgery and gastroenterology. The process involves the steps of (a) flame treating a surface of the silicone or silicone based material and (b) bonding the polyurethane to the flame treated surface of the silicone or silicone based material.

Disclosed is a method of joining resin members that includes: forming a coating layer by applying a solvent to a surface of a resin member, the solvent allowing the thermoplastic resin to have a degree of swelling of 1.05 or more and 3.00 or less when the thermoplastic resin is swollen by the solvent, and having a boiling point B C. of R C. or lower where R C. is a glass transition temperature of the thermoplastic resin; laminating resin members one another via the coating layer to form a laminate; and pressing the laminate in the lamination direction while heating at a heating temperature H C. that is equal to or lower than R C.

Method of manufacturing a microfluidic device comprising an inflexible polymeric substrate, one or more flexible polymeric substrate(s) and one or more microfluidic channel(s) enclosed between the substrates comprising a) providing a master form including rim protrusions defining an enveloping shape for the microfluidic channel(s) to be produced and enclosed between the substrates, b) placing one or more flexible polymeric substrate(s) each having a layer thickness of less than 800 m onto the master form, wherein one flexible polymeric substrate is in contact with the rim protrusions of the master form, c) placing an inflexible polymeric substrate with a layer thickness of equal to or more than 800 m onto the flexible polymeric substrate(s), and d) ultrasonically welding the one or more flexible polymeric substrate(s) and the inflexible polymeric substrate at the rim protrusions. By the inventive method microfluidic devices via ultrasonic welding without using energy directors can be obtained.

A deflection member that includes a reinforcing member that includes a resin coating, and at least one tile fastened to the resin coating.

A deflection member that includes a reinforcing member that includes a resin coating, and at least one tile fastened to the resin coating.

A process for making water-soluble pouches having at least one compartment on a sealing plane is disclosed. The process is characterized by the difference in the first water-soluble film heating temperature and the second water-soluble film heating temperature being reduced substantially. The resulting water-soluble pouch comprises of almost symmetrically shaped individual compartments relative to the sealing plane respectively and optionally with different depth of each compartment enabling stereoscopic and contemporary appearance to the consumer.

The present invention is directed to a method of making at least a portion of a garment that includes at least one three-dimensional contour. The disclosed method includes providing a fiber and solvent mixture that includes fibers and a solvent capable to causing a plurality of covalent bonds to be created between the fibers. In many embodiments, the plurality of covalent bonds form when a catalyst, such as heat, is provided to the fiber and solvent mixture. The process can be performed using, for example, either a 3D printer or mold form. The fibers used can be natural, synthetic, or a blend of natural and/or synthetic fibers. The solvent preferably includes ionic salts in water.

A nasal/oral cannula for collecting a flow of exhaled gases and its method of manufacture are disclosed. The cannula comprises an elongated tubular body having a first and a second end portion, a surface and an internal volume; a wall internally disposed within said tubular body, said wall defining a first subvolume of said internal volume in the lengthwise direction of the tubular body; and an inlet through said surface, for introducing exhaled gases into said first subvolume. The first end portion defines an exit port for exhaled gases from said subvolume, and said wall is arranged directly adjacent to said inlet.
