Abstract: System for processing technical surfaces, in particular surfaces of essentially rotationally symmetrical work pieces (3), comprising at least one processing unit (4) and one motor-driven work-piece carrier (1) and, mounted thereon in rotatable fashion, at least two or more holders (5) that feed work pieces (3) to the processing unit (4), characterized in that the processing unit (4) includes means (6) serving to exert an essentially constant hold-down pressure on the surface of the respective work piece (3), while the motor drive is so designed as to control the feed-in-timing sequence of the work pieces (3) and the duration of their processing cycle in the processing unit (4).

Abstract: Heat exchanger panel and process of making such panel comprised of selectively clad or bonded metal plates made of a material which cannot be cold roll bonded without great difficulty, if at all, with at least one channel disposed therebetween. An adhesive layer of an amorphous metal is provided between the plates for permanently joining the plates together by cold roll bonding in the area of the adhesive layer.

Abstract: A method of laminating first and second metal sheets to one another, comprises the steps of superposing the metal sheets and including therebetween a layer of amorphous metal and laminating the sheets to one another. During the lamination a pressure is applied by cold rolling for bonding the first and second sheets together.
