Patent number: 5915678Abstract: A novel system for kinematically positioning planar surfaces such as printed circuit board components and elements of material, where one element has precisely formed and positioned (e.g., punched) slots that fit loosely over three corresponding posts, such that when a bias force, such as gravity from a tilted plane or a combing action, or expanding bladder on the posts, is applied, the surfaces are referenced to one side of the slots to in effect form a planar kinematic coupling so the relative planar position and orientation is defined with great accuracy and repeatability; such also allowing an entire factory system to be built where each piece of precision manufacturing equipment can use this planar kinematic coupling to achieve great accuracy in the manufacture of printed circuit boards or the like to allow for the use of ever smaller electronics components.Type: GrantFiled: May 30, 1996Date of Patent: June 29, 1999Assignee: Aesop, Inc.Inventors: Alexander H.

Patent number: 5826866Abstract: Each of a plurality of thin-walled workpieces is held for machining in a machine in a respective rigid holder. Ends of unmachined workpieces are each first imbedded in a molten body of a metal alloy having a melting point between 45.degree. C. and 140.degree. C. contained in a respective one of the rigid holders in a cooling station and having a negative expansion coefficient. The holder and the alloy body are cooled in the cooling station to solidify the body around the imbedded end of the unmachined workpiece and the cooled holder is displaced with the unmachined workpiece from the cooling station into the machine. After machining of the workpiece in the holder, the holder is displaced from the machine into a heating station where it is heated to melt the alloy body. Then the machined workpiece is lifted out of the molten body in the heating station and the holder with the molten alloy body is recirculated from the heating station to the cooling station.Type: GrantFiled: February 3, 1997Date of Patent: October 27, 1998Assignee: Ernst Thielenhaus KGInventors: Manfred G. Becker, Peter C. Dinardi, Kenneth J. Sprenger, Timothy S. Guitar
