Abstract: Disclosed is an iron, comprising an aluminum sole plate which is provided with a coating which is provided by means of a sol-gel process and wherein an intermediate layer is present between the aluminum sole plate and the sol-gel coating. The intermediate layer comprises a porous layer of aluminum oxide. Also described is a method of manufacturing such an iron. The method comprises the steps of providing an aluminum sole plate, applying a porous intermediate layer of aluminum oxide by electrochemical treatment of the aluminum sole plate in an electrolyte comprising a solution of phosphoric acid, and providing a sol-gel coating on the treated sole plate. Furthermore, an aluminum sole plate which is suitable for use in an iron is disclosed.

Abstract: A ripple suppressor/compensator useful in the general area of motion control and applicable to a wide range of servomechanisms exhibiting a force ripple characteristics, including the permanent magnet linear motors. An adaptive feed-forward control signal is generated which compensates for the ripple force, thus allowing for more precise tracking performance to be achieved.

Abstract: In general terms, the invention can be described as a computer system for enhancing the performance of underlying policies and execution-rules of real-world activities. The computer system includes a demand input section for providing demand information to drive the system. A real-time software application has a series of discrete steps for implementing the underlying policies and execution-rules of the activities and converts the demand information into instructions. A simulation-time operations-simulation model implements the underlying policies and execution-rules of the activities and receivers, the instructions. A control section includes a synchronization clock which synchronizes the discrete steps of the software application with the operations-simulation model by delaying the execution of some of the discrete steps and which communicates the instructions from the software application to the operations-simulation model.

Abstract: This invention presents the process of direct laser casting of copper alloys: Cu—X (where X=Ni, Fe, W;) and their composites Cu—Y and Cu—X—Y (Y=WC, TiC, Ti+C) from powders prepared using mechanical mixing and ball milling processes. Since the metallic powder is combined with a low melting point Cu metal, which has good thermal and electrical conductivity, the combination allows the powder mixture to be melted by CO2 laser and re-solidified into a part with good mechanical properties and conductivity. The laser casting process for the Cu-based in-situ formation and the material systems formed using the said method have been developed. The process can be used to fabricate complex three-dimensional objects by multi-layer overlapping and the material systems can be used to build rapid tooling due to the properties of good thermal conductivity and low wear rate.

Abstract: A method of laser marking which comprises applying a laser beam to a metal surface under the influence of an assist gas to produce durable, repeatable and striking colors on the metal surface. The method provides an easy and flexible alternative to conventional metal decorating techniques.
