Abstract
Abstract A device for making memory storage matrices comprising a wire tensioning means for Y drive wires provided with individual weights for each pair of the Y axis drive wires, each weight taking the form of a plate and having a recess disposed in the proximity to the upper edge of the weight which accommodates a pulley gripping the middle of a Y axis drive wire with cores strung at both of its ends, making it possible to increase the supply of core-stringing the wires, which considerably improves the uniformity of wire tensioning and provides for a more reliable checking of the electrical characteristics of the cores during the threading thereof.

Claim 1
Independent Claim
188 words
A device for making memory storage matrices of the type wherein a plurality of Y axis drive wires are disposed in spaced apart relationship and include memory cores strung thereon, and wherein a plurality of X axis drive wires are threaded through said cores in a direction generally perpendicular to the Y axis drive wires, said device comprising; an upper terminal plate incorporating a plurality of spaced terminal means to which the respective ends of the plurality of Y axis drive wires are adapted to be connected; a plurality of weights disposed beneath said upper terminal plate, each weight having upper and lower edges and a thickness equal to twice the spacing of said terminal means on said terminal plate, a recess being provided in proximity to said upper edge of each weight, and a pully being disposed in each recess, whereby each Y axis drive wire can be looped around the pully in a respective weight to form an adjacent pair of wires in the matrix and thereby pulled taut by the weight; and a means for threading the memory storage matrix with X axis drive wires.
