Abstract:
An information processing system includes a plurality of data processing tools, an atomic information repository, and a plurality of generated translation engines. Each data processing tool processes data in accordance with an associated data model, and in the process generates access requests for accessing data in accordance with its associated data model. The atomic information repository stores data items using an organization in an atomic data model which corresponds to the combination of the data models associated with all of the tools. Each translation engine is associated with one of the tools. Each translation engine receives an access request from its associated tool in the associated tool's data model and performs a translation operation to translate the request to the repository's atomic data model, and initiates an access operation with the repository in connection with the translated access request. A system manager is provided which can, when a new tool is added to the system, update the repository's atomic data model to reflect the added tool's associated data model, generate a translation engine for the new tool, and also update the translation engines associated with the existing tools to reflect the update.
Method And Apparatus For Making Filament Wound Cylindrical Structres
An apparatus and method is disclosed for the fabrication of cylindrical structures (26) by filament winding of resin impregnated filaments around a novel cylindrical mandrel assembly (10) whereby the mandrel assembly (10) and fabricated cylindrical structure (26) are easily separated after curing of the resin impregnated materials. The invention utilizes an inner, hollow cylindrical mandrel member (11) onto which a metal cable (12) is wound over afterwhich segmented outer mandrel sections (13) are connected to the inner mandrel member by fastener devices (20) installed from the inner side of the inner mandrel member (14). The resin impregnated filament is then wound over the outer mandrel segments (13) and cured in a conventional manner. After curing, the fasteners (20) are removed from the inner side of the inner mandrel (11), and the cable (12) is removed by pulling it from one end of the mandrel assembly (10). With the cable (12) removed, clearance is provided so that the inner mandrel (11) can be removed from the outer segmented mandrel (13), and once the inner mandrel (11) is removed, the outer, segmented mandrel (13) is disassembled and removed inwardly from contact with the cured filament wound cylinder (26).

International Classification:
B05D 118 B05D 302 B05D 312 B05D 512
US Classification:
427120
Abstract:
A method of applying substantially consistent and uniform coatings of a corrosion preventive compound to metallic cable lengths is disclosed which involves the immersion of the cable into a liquid coating compound of controlled viscosity followed by wiping the cable with a compound-containing material upon withdrawal of the cable from the compound.
