Abstract: A raster imaging device with the capability of computing a storage or retrieval address of color components (channels) of each pixel "on-the-fly" as the data is stored into a color image memory or retrieved from the memory, respectively. This computation of the address allows simultaneous image data format conversion and image reorientation.

Abstract: In order to permit a user to predict the density, color balance, and contrast of an image to be printed on a hardcopy printing device, an image on a video color display device is provided with a uniform surround of controllable luminance and chrominance levels, the uniform surround being large enough in proportion to the image to mimic the viewing conditions of the final hardcopy. The presentation of user controls for image manipulation is integrated on the same color display device, with controllable brightness as compared to the controlled, uniform surround, to minimize disruption of the user's visual system as pertains to the perception of density, color balance and contrast. The user controls on the display device are faded away into the controlled, uniform surround for critical judgment of the video image. The user controls are subsequently restored to their original, controlled brightness. The rate at which the user controls fade in and fade out on the display device is controlled.

Abstract: This invention relates to a novel cell growth-promoting material for use as a supplement to basal tissue culture media for the cultivation of animal cells in vitro and to the method for its preparation. More particularly, it relates to an infusion consisting of growth-promoting material from adult, calf or fetal bovine blood clots as a supplement to basal media for cultivation of animal cells in vitro.

Abstract: A tire cutting machine can rotatably support a wheel mounted and inflated tire with the tread thereof facing one or the other, or both, of a groove cutter, and a rotatable siping blade assembled with a lead screw. The tire can be driven by a spiked roller for cutting circumferential grooves, or can be driven by the siping cutter and a lead screw when siping. The siping cutter can be shifted axially of the tire by a motor-driven feed screw with adjustable automatic shut-off.

Abstract: The present tire cutting machine can rotatably support a wheel mounted and inflated tire with the tread thereof facing one or the other of a groove cutter, and a rotatable siping blade assembled with a feeler. The tire can be driven from the wheel for cutting circumferential grooves, or can be driven by the siping cutter and/or a lead screw when siping. When the feeler and siping blade engage the tire, the feeler maintains the siping blade in proper relation to the tire tread for said siping blade to cut and move around the tire tread to effect minute lateral cuts or sipes in a section of the tire tread.

Abstract: The present tire siping machine can rotatably support a wheel mounted and inflated tire with the tread thereof facing a driven and adjustably mounted siping blade and feeler adjustably connected to the siping blade for permitting the feeler and siping blade to engage the tire whereupon the feeler maintains the siping blade in proper relation to the tire tread for said siping blade to cut and move around the tire tread to effect minute lateral cuts or sipes in a section of the tire tread to be followed by repositioning of said blade to other sections of the tread and repetitions of the siping operation until the entire tire tread is siped.
