Abstract
Abstract Read only data planes for use with solenoid array memories are woven by processes which employ weaving conductive and nonconductive strands of material as both the warp and the woof (filler) of a fabric. The data planes take two basic forms, one being a woven mat of substantially the same length and width dimensions of its associated memory stack, and another being in the form of a strip which may be folded back and forth, the folded sections being co-extensive to form the data plane. Coding is effected by interrupted and/or connecting selected conductors.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
The method of making read only solenoid array memories, said method comprising the steps of: weaving an array of vertical and horizontal groups of conductors and insulating strands substantially in a single plane, said woven plane having solenoid receiving apertures therethrough at selected positions between vertical and horizontal groups of conductors, and said conductors being generally insulated from each other; establishing electrical connections between selected vertical and horizontal conductors such that an electrical circuit path is formed about and spaced apart from each said solenoid receiving aperture, thereby producing a master pattern; inserting a solenoid core in each of said solenoid receiving apertures; and interrupting the individual conductors of said master pattern at selected points such that a plurality of individual circuit paths selectively thread or bypass each said solenoid core thereby providing said memories with a selected data code.
Claim 2
Independent Claim
140 words
The method of making read only solenoid array memories, said method comprising the steps of: weaving an array of vertical and horizontal groups of conductors and insulating strands substantially in a single plane, said woven plane having solenoid receiving apertures therethrough at selected positions between vertical and horizontal groups of conductors, and said conductors being generally insulated from each other; establishing electrical connections between selected vertical and horizontal conductors such that an electrical circuit path is formed about and spaced apart from each said solenoid receiving aperture, thereby producing a master pattern; inserting a solenoid core in each of said solenoid receiving apertures; and interrupting the individual conductors of said master pattern at selected points such that a plurality of individual circuit paths selectively thread or bypass each said solenoid core thereby providing said memories with a selected data code.
Claim 3
Dependent Claim
32 words
The method of claim 1 wherein said array is woven in a continuous fabric and further including the step of cutting said fabric into desired lengths prior to producing said master pattern.
Claim 4
Dependent Claim
26 words
The method of claim 1 further including the step of cutting said array into desired lengths after said data code has been provided in said plane.
Claim 5
Dependent Claim
30 words
The method of claim 1 further including the step of coating said array with electrically insulative material to thereby bond said insulating strands to one another and to said conductors.
