摘要:
A system to place one or more rovings made from composite material on a substrate. The system includes at least a roving-laying head configured to lay at least one roving, an electricity generator and at least one plasma torch. The plasma torch mounted on the roving-laying head and powered by the electricity generator. The plasma torch being further supplied with at least one plasma-forming fluid to generate at least one plasma jet suitable for heating the one or more rovings to be laid on the substrate.

摘要:
An oven for baking a thermally curable binder in a mat of mineral fibers, including plural compartments through which the mat of fibers passes successively, the mat being compressed and transported through the compartments by gas-permeable upper conveyors and lower conveyors, each compartment having a length along a direction of movement of the mat and including a mechanism introducing a hot air flow, located either below or above the fiber mat, and a mechanism extracting the air after having passed through the mat, respectively arranged either above or below the opposite face of the mat, so that the binder is progressively brought to a temperature higher than its curing temperature. In one compartment the mechanism introducing hot air includes air inlets that open partly on openings formed on a first lateral side of the compartment and partly on openings formed on the opposite lateral side of the compartment.
摘要:
Solid or semi-solid feedstock is melted in an open bottom electric induction cold crucible furnace. Directionally solidified multi-crystalline solid purified material continuously exits the bottom of the furnace and may optionally pass through a thermal conditioning chamber before being gravity fed into a transport mold where an ingot of the purified multi-crystalline solid material is transported to a remote holding area after the transport mold is filled with the multi-crystalline material and cut from the continuous supply of material. Cool down of the ingot is accomplished remote from the open bottom of the cold crucible furnace.

摘要:
Manufactured articles and methods of producing such articles are disclosed where the article has a thermoplastic polymer component and a curable polymer component. The curable polymer may be moisture-curable polymer, or microwave, dielectric or radio frequency curable polymer. The articles may be manufactured by a variety of polymer processing methods including extrusion, co-extrusion, co-molding, injection molding and calendering. A variety of articles and shapes may be made by the method including electric wire and cable, and weatherstripping.
摘要:
An electrospinning process and apparatus for forming aligned electrospun fibers. A time-dependent (AC) voltage is applied to a multi-electrode collector in order to temporally control the location and orientation of fiber deposition.

摘要:
A system and methods for manufacturing plastic parts with textile covering. The system includes a mold (10) having at least one fixed portion (102), at least one movable portion (101), a first surface (100) facing the textile covering, a second surface (110) exterior to the first surface (100). The system is characterized in that it comprises at least one air inlet (11) connectable to a source of compressed air for providing air to heating means (12) for heating air coming from the air inlet (11) and producing hot air, at least one air outlet (14) for air coming from the heating means (12), situated in the first surface (100) of at least one of the portions (101, 102) of the mold (10), and conduction means (13) for conducting the hot air from the heating means (12) to each air outlet (14). The method comprises Injecting hot air over the part in areas of textile covering.
