Abstract: A method is disclosed of preparing an extended tonal range pre-press proof of an original subject in color using photographic color print paper. Yellow, magenta and cyan color halftone separation negatives and positives of the original subject are prepared along with a pin dot maker film positive (PDM) which is clear only in the extremely fine highlight detail areas of the color original. After exposure of photographic color print paper to combinations of the yellow, magenta and cyan halftone separation negatives and positives through respective blue, green and red filters, in each instance the yellow, magenta and cyan halftone negatives are used to again expose the undeveloped print paper to blue, green and red filtered light respectively in association with the PDM. A black separation halftone negative may also be used in the process to improve the final appearance of the product. The resulting pre-press color proof has enhanced fine highlight color detail.

Abstract: A process for manufacturing powder metallurgy (P/M) preforms which are conditioned for optimum intrinsic workability is described which comprises steps of heating a quantity of P/M material in a can to a first preselected temperature under vacuum to degas the material, compacting the canned material at a second preselected temperature under pressure to provide a compact of the material; or cold compacting the powder to about 75% density and degassing it at suitable temperature and then vacuum hot pressing the powder at about 0.

Abstract: An improved hot forming method for metals, alloys and the like, and in particular, for difficult to process high strength and high temperature metals and alloys of particular use in aerospace applications, is described, which comprises the steps of generating flow stress data as a function of strain rate and temperature on samples of the material at predetermined strain within predetermined ranges of temperature and strain rate; determining from that data the strain rate sensitivity and power dissipation efficiency of the material within the ranges of temperature and strain rate represented by the generated data; selecting values of strain rate and corresponding temperature for a selected value of the dissipation efficiency for the material; and hot forming the material at the selected strain rate and temperature values to a predetermined shape.

Abstract: A process is disclosed for preparing a pre-press proof of an original subject having highlight, midtone and shadow tone areas using a color print paper wherein the dyes of the print paper are brought into substantial color compliance with the yellow, cyan and magenta process inks to be used in producing a lithographic reproduction of the original subject. The tonal range of the proof image is also extended to closely match that of the final printed product. After determining the densitometer readings for yellow, magenta and cyan through blue, green and red filters respectively for the print paper and the process inks, the print paper is exposed to light through each filter with an appropriate color separation halftone negative over the film and with combinations of filters being used for hue correction of the yellow, magenta and cyan film dye coupling dyes.
