摘要:
A method of manufacturing a de-icer assembly includes positioning a first welded-material layer and a second welded-material layer between a die and a die base of a die-based welding system, wherein at least one of the die and the die base includes a welded-portion pattern configured to weld the first welded-material layer to the second welded-material layer in the pattern such that inflatable portions are formed within the welded-portion pattern formed in the de-icer assembly between non-welded sections of the first welded-material layer and the second welded-material layer, pressing the first welded-material layer and the second welded-material layer together between the die and die base, and applying high energy to the die-based welding system using a high energy source such that the first welded-material layer and the second welded-material layer are welded together at the areas in the shape of the welded-portion pattern to form a welded de-icer assembly.

Container for foodstuffs, in particular coffee, comprising a central body (11) made of flexible material, a bottom (12) welded to a lower end (15) of said central body (11), and a lid (20, 39) welded to an upper end (21) of said central body (11) by means of an upper ring (25, 45), made of rigid plastic material, the container further comprising a lower ring (13), also made of rigid plastic material, which makes said bottom (12) solid with said central body (11), wherein the bottom (12) and/or the lid (20, 39) are welded peripherally, respectively, to the lower ring (13) and/or to the upper ring (25) and inside the central body (11), in an intermediate position between the central body (11) and, respectively, the lower ring (13) and/or upper ring (25).
摘要:
A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison.

Embodiments of the present invention relate to a UV -curable polyurethane-methacrylate (PUMA) substrate for manufacturing microfluidic devices. PUMA is optically transparent, biocompatible, and has stable surface properties. Embodiments include two production processes that are compatible with the existing methods of rapid prototyping, and characterizations of the resultant PUMA microfluidic devices are presented. Embodiments of the present invention also relate to strategies to improve the production yield of chips manufactured from PUMA resin, especially for microfluidic systems that contain dense and high-aspect-ratio features. Described is a mold-releasing procedure that minimizes motion in the shear plane of the microstructures. Also presented are simple yet scalable methods for forming seals between PUMA substrates, which avoids excessive compressive force that may crush delicate structures. Two methods for forming interconnects with PUMA microfluidic devices are detailed. These improvements produce a microfiltration device containing closely spaced and high-aspect-ratio fins, suitable for retaining and concentrating cells or beads from a highly diluted suspension.

The invention relates to a method of assembling pre-impregnated plies by local isolated polymerization of the assembly region (30) under the action of a radiation to which the resin of the prepreg is sensitive. The assembly method makes it possible in particular to produce very large sized gossamer structures (7) in the form of a concertina-folded tube which is deployed by injecting pressurized gas once into the space then stiffened by polymerization under the effect of the same radiation. The pylon concerned (7) thus comprises two structural elements (10, 20) secured end to end while at the same time maintaining its flexibility and firmness qualities.

An innerliner for tire is formed by laminating a composition containing an elastomer component onto a resin layer and then irradiating energy beams required for generating partial crosslinking between the resin layer and the elastomer component.
摘要:
A method of manufacturing a stiffened composite structure comprising the steps of: molding the structure around a mandrel tool (1); using digital camera data to record the positions of desired pad locations on the structure; bonding pads (4) to the structure at the desired locations; curing the pads and structure; forming stiffeners from composite material including forming a plurality of tabs at points on the stiffener corresponding to the pads on the structure; using a laser theodolite (3) connected to receive the stored information of the pad locations relative to a datum point on the structure to locate the stiffener tabs accurately on the pads; and, bonding the stiffeners to the structure via the tabs and pads. Preferably the location tabs and pads are machined off the final stiffened structure after autoclaving.
