摘要： A display is disclosed for indicating in the peripheral vision of a viewer the deviation between the actual position of a target and a reference position such as an aiming point. Light sources are arranged around a common circle which is of a particular size such that when viewed from a particular distance, the viewer sees the display by peripheral vision. There are two sets of light sources, one of which indicates the azimuth and elevation deviations of the target from the aiming point and the other of which may be used to indicate range. The direction of azimuth and elevation deviation is indicated by flashing selected light sources around the circle and the magnitude of deviation is indicated by flashing those light sources at a flash rate indicative of the magnitude. Range is indicated by causing the second set of light sources around the circle to illuminate upon attainment by the target of a certain range.

摘要： A laminated veneer hammerboard for a drop forge press comprised of a series of plies of hard, high density wood preferably of the order of a peeled hard maple veneer with the grain of at least most of said veneer plies running along its length, each of said plies of the hammerboard having a thickness in the range of 1/32" to 3/16", and glue deposited between the plies securing the plies together and providing a relatively large number of hard glue surfaces enhancing the wearability of the board, said plies having opposite vertical edges positioned for edgewise engagement with lift rollers on a drop forge press.

Vertical edges of each ply being disposed at opposite ends of the hammerboard rather than along the width thereof, thus enabling each roller to engage an outer side surface of the outermost ply on each side of the hammerboard rather than directly against opposite vertical edges of each ply.
