Abstract: Spacing data for right-hand margin justification is graphically computed by a pair of intercooperating scales, one of which has biaxial color coded indicia, the other of which includes a uniaxial scale. The uniaxial scale is readable in conjunction with the biaxial color coding directly in terms of a justification problem solution. Also, a self-powered motion takeoff device is provided for automatically positioning one of the two scales by following motion of a typewriter letter feeding device within a predetermined proximity of the right margin.

Abstract: WALL THINNNING OF MOLDINGS MADE BY PRESSURE DEFORMATION IS AVOIDED BY LOCALLY PRECONDITIONING THE MATERIAL STRUCTURE OF A SHEET OF SUITABLE MATERIAL, FOR EXAMPLE, A SUPERPLASTIC METAL. THE PRECONDITIONING INCLUDES A HEAT TREATMENT OF THE MATERIAL STRUCTURE IN SELECTED PORTIONS OF THE SHEET TO REDUCE THE STRAIN PLASTICITY IN THESE PORTIONS DURING THE FORMING PROCESS.
