摘要:
A method of producing a multi-lumen elongate body for a medical device. Unlike known methods requiring a solid core of material inserted into each lumen to maintain patency of the lumens during manufacture, the present method obviates the need for a solid core within one or more minor lumens, which saves cost and production complexity. One or more material overlay and mesh overlay steps may be used to produce the multi-lumen elongate body, but only the main lumen may include a solid core therein during all manufacturing steps. The one or more minor lumens may each be defined by a lumen tube having a sufficient stiffness to withstand external pressure during all manufacturing steps without the need for a solid core within.

A repair solution for a wind turbine blade is described. The repair solution includes the application of a layer of viscous coating material to the section of the blade to be repaired, which is cured to form a repaired surface. The layer of viscous coating material may be temporarily covered during the curing process using a film of Low Surface Energy material, to prevent defects in the repaired surface from dust, insects, etc. Additionally or alternatively, a temporary shield may be erected adjacent the curing layer of coating material, to allow for the control of the temperature and/or humidity levels of the region adjacent the curing material, to provide for more effective control of the curing process and to allow for repairs to be carried out for a wider process window.

A gas-permeable porous fluororesin membrane (4) made of a fluororesin is welded to a resin component (2) made of a thermoplastic resin using a welding horn (62) having a working surface (62p) adapted to be brought into contact with a work object and provided with a projection (62t). The working surface (62p) of the welding horn (62) is provided with, for example, a plurality of projections (62t). The plurality of projections (62t) may be arranged in a grid pattern on the working surface (62p).
摘要:
A thermal interface device comprises a film of thermal grease intended to be inserted between a first object and a second object, and a microporous seal encircling the periphery of the film of thermal grease. A manufacturing method comprises steps of: deposition of the microporous seal on the first object in such a way as to form a closed frame on the first object; deposition of the thermal grease on the first object, inside the closed frame; smoothing of the thermal grease bearing on the frame of microporous seal, making it possible to form the film of thermal grease encircled by the microporous seal; and deposition of the second object on the film of thermal grease.
摘要:
A method of increasing the tensile strength of polymer films is provided. The creation of the load distribution elements in polymer films necessary to achieve this result is described. Application of the present invention to increase suture retention in a surgical polymer film is also provided.
摘要:
This invention relates to methods for manufacturing large PTFE parts by compression molding followed by sintering. The method comprises layering modified and unmodified PTFE in a mold, and compressing the layers to form a preform part. Once the preform parts are formed, they are assembled such that the areas of preform parts which are to be bonded together are the modified PTFE sections. The parts are then sintered and the modified PTFE sections bond together creating a strong, durable, bond.
摘要:
Molded preformed polytetrafluoroethylene structures are comprised of at least one preformed section. The homogeneous PTFE section yields a unitary non-homogeneous polytetrafluoroethylene structure when isostatically molded together with either polytetrafluoroethylene powders or polytetrafluoroethylene preformed sections.
摘要:
A method of manufacturing a fibre comprising a lined channel, using a draw apparatus, the method comprising: providing a preform, comprising a channel extending through the preform, to the draw apparatus; feeding a liner into the channel; heating a portion of the preform; and drawing the heated portion of the preform in order to form a fibre, wherein the liner is held within the channel of the fibre to provide a lined channel within the fibre.
摘要:
The present invention provides a process for preparing a functionalised polymeric chromatography medium, which process comprises (I) providing two or more non-woven sheets stacked one on top of the other, each said sheet comprising one or more polymer nanofibres, (II) simultaneously heating and pressing the stack of sheets to fuse points of contact between the nanofibres of adjacent sheets, and (III) contacting the pressed and heated product with a reagent which functionalises the product of step (II) as a chromatography medium.
