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.
Abstract:
A solder form facilitates replacement of receptacle terminals that extend through blind connecting through-holes of a plurality of circuit boards. A hairpin conductor within the solder form spreads apart when the form is melted to carry solder to a replacement terminal and to the conductive surface of a throughhole.
Abstract:
A loop-shaped circuit test point formed from resilient wire held in a rigid mounting block through the combination of torsion and compression. When the top of the loop is cut, the two ends will spring apart isolating the circuit connection. When reconnection of the loop is desired the two top sections are passed by each other and crossed over and released thus allowing two section of the loop to hold each other together.
Abstract:
A terminal clip for the solderless connecting of electrical conductors to terminal posts, wherein the clip comprises a tubular body section having a flanged section formed on at least one end, and wherein the connection relies on a compressive metallic deformation in the tubular section against the conductor for clamping the conductor to the post. The clamping force provided by the clip is determined in accordance with the configuration and/or the hardness of the flange edge in combination with the configuration and/or the hardness of the strain relief point, or knee, where the flange section joins the tubular section. In response to a compressive force being applied to the clip in a direction parallel to the axis of the tubular section, the material at the knee yields before that of the flange edge, thereby reducing the internal diameter of the tube at the knee for providing the clamping connection.
Abstract:
A planar receptacle for pluggable mounting of electronic component leads therein which is formed by applying a resilient, electrically conductive material over an apertured base, and forming a pattern of planar cuts in said resilient layer over each aperture in the base such that when an electronic component lead is pressed onto the resilient layer over an aperture, the resilient layer will deform into the aperture to form at least one contact apron capable of supporting said electronic component lead and capable of making electrical contact with said lead.
Abstract:
A printed wiring card file including a support and stabilization structure to which notched card guide sections may be clamped. The card guides provide vertical alignment of the printed wiring cards and the support and stabilization structure may be arranged such as to accommodate wiring cards of any desired height.
Abstract:
A tool for the installation of flanged tubular type wire clamp terminal clips over a wire lead and post terminal includes a plurality of finger members pivotally mounted about a hollow central push rod such that they close radially toward the rod on the application of axial pressure. Means for applying axial pressure is provided whereby a flanged tubular type wire clamp terminal clip is gripped between the fingers and push rod. As pressure is increased the fingers and rod exert opposing axial forces on the terminal clip sufficient to deform the cylindrical clip wall inwardly thereby securing the wire to the terminal. In an alternative embodiment a solid central push rod is employed to effect removal of the terminal clips.
Abstract:
Woven-wire, transformer memories that are to be occasionally altered by adding conductors to their braid, have an end of each of the legs of their cores extended past a usual U-shaped portion. The end that is extended is readily moved outward momentarily in opposition to a mounting spring to form between the leg and the rest of the core a gap that is wide enough to permit passage of additional conductors for storing information. The conductors to be added are first braided on the extended portions of the legs, and their coding positions are checked before the memory is interrupted only long enough to move the added conductors a short distance along the legs through the gaps.
Abstract:
A cable clamp mounted to a printed-wiring circuit board has means for directing a cable in a chosen one of several directions. The outer face has a plurality of slots radiating from the position in which the cable is clamped, and the cable may be bent into a slot and held by a constraining device in a direction according to which slot is chosen to contain the cable.
Abstract:
An arrangement for terminating a wire to a terminal post wherein the wire is accurately located with respect to the terminal post by the configuration of the post and/or a spring clip which forces the wire against the terminal post without translation of the wire with respect to the post.
