摘要:
A method of repairing a composite component (1) having a damaged area including: laying a composite lay-up (7) over the damaged area; locating at least one pressure chamber (3, 4) over the damaged area, the pressure chamber including a displaceable abutment face (5, 6); circulating fluid at an elevated temperature and pressure through the pressure chamber (3, 4) to thereby compress the lay-up (7) between the abutment face of the pressure chamber and the composite and elevate the temperature thereof to effect curing of the lay-up.

A novel occlusive dressing which allows the escape of fluid and air in cases of penetrating thoracic trauma. The dressing comprises a one-way valve that lies flat on the body of the patient during use such that the fluid from the wound is able to drain away without air from the surrounding environment penetrating the wound.

An apparatus for assembling a liner from a plurality of longitudinal sections of flexible material having longitudinal edges adapted to be joined one to another to form the liner includes a path means along which the longitudinal sections of flexible material can be conveyed in a laterally reduced condition, an assembly zone at which the longitudinal edges can be joined together to form the liner, and a guide structure about which the flexible material can turn upon exiting from the path means to provide an inner section and an outer section turned back with respect to the inner section. The guide structure presents a guide, surface over which the longitudinal sections of flexible material can pass, the surface being configured to facilitate spreading of each longitudinal section from the laterally reduced condition.
摘要:
A method, system, and computer-usable medium for automatically identifying the source of copied software. A single identifying marker can be embedded in a common code base associated with different software application products. A suspected copy of a product can be fed to an automated tool, which extracts the type of object code, which is then scanned to determine the identifying marker. The automated tool can therefore identify the exact product and version of the suspected copy utilizing the identifying marker and the type of object code without the need for labor-intensive modification of the common code base and product-specific markers.
摘要:
An apparatus for producing tubes formed from fiber reinforced composite material, the apparatus including: an elongate hollow mandrel (3) having an internal mandrel cavity (5), the mandrel having an external surface (7) upon which reinforcing fiber material (9) can be wrapped to provide a composite lay-up (10) supported thereon; and fluid flow means (11) for enabling heat transfer fluid of different temperatures to be circulated through the mandrel cavity (5), such that when fluid at an elevated temperature is circulated, heat is transferred from the fluid, through the mandrel (3) to the composite lay-up (10) for curing or forming said lay-up.

摘要:
The invention relates to a slide bearing composite material which comprises a support layer from a copper alloy and a bearing coating applied to said support layer. The copper alloy may comprise 0.5 to 5% by weight of nickel, 0.2 to 2.5% by weight of silicon, ≦0.1% by weight of lead. The bearing coating can be a galvanic layer, a sputter layer or a plastic layer. The invention also relates to methods of producing such a composite material.
摘要:
A system for producing composite or bonded metal components including: first and second pressure chambers, each pressure chamber having an elastically deformable chamber wall; means for circulating fluid at an elevated temperature and pressure through each said pressure chamber; and at least one mould assembly including at least one separate mould section providing a mould cavity within which a composite or bonded metal lay-up can be located; wherein when the system is in use, the pressure chambers are held together with the elastically deformable chamber walls located in opposing relation, the at least one mould assembly containing a said lay- up being accommodated between the chamber walls while fluid at elevated temperature and pressure is circulated through each pressure chamber such that the lay-up can be compressed and cured or formed.
摘要:
Method and apparatus for the production, forming bonding, joining and repair systems composite and metal components utilising at least one pressure chamber having a displaceable abutment face, wherein fluid is circulated at an elevated temperature and pressure through the pressure chamber.
摘要:
The present invention is directed to a device for vacuum holding a dental veneer during the trial placement of a veneer on a tooth, application of adhesive to the veneer and final placement of the veneer on the tooth. The device includes a flexible suction cup with a connecting air bulb. The cup is placed on the external surface of the veneer while squeezing the air bulb. The veneer is held on the cup until the air bulb is squeezed. The instrument allows for multiple veneers to be simultaneously coated and placed,
